                                 PROXY STATEMENT

     This Proxy Statement is being furnished in connection with the solicitation
of proxies on behalf of the Company's Board of Directors (the "Board") for the
2002 Annual General Meeting of Members (the "2002 Annual Meeting"), to be held
on May 20, 2002 at the Princess Hotel, Hamilton, Bermuda. The solicitation of

proxy materials will be distributed to registered Members on or about April 1,
2002.

     Holders of the Company's common shares ("Members"), par value $1.00 per
share ("Common Shares"), as of the close of business on Friday, March 22, 2002,
the record date, are entitled to vote at the meeting.

     You can ensure that your Common Shares are properly voted at the meeting by
completing, signing, dating and returning the enclosed proxy card in the
envelope provided. Members who hold their Common Shares in a brokerage account,
an employee benefit plan or through a nominee will likely have the added
flexibility of voting their Common Shares by telephone or over the internet. A
Member has the right to appoint another person (who need not be a Member) to
represent the Member at the meeting by completing an alternative form of proxy
which can be obtained from the Corporate Secretary or by notifying the
Inspectors of Election (see page 19). Every Member entitled to vote has the
right to do so either in person or by one or more persons authorised by a
written proxy executed by such Member and filed with the Corporate Secretary.
Any proxy duly executed will continue in full force and effect unless revoked by
the person executing it in writing or by the filing of a subsequent proxy.

     Sending in a signed proxy will not affect your right to attend the meeting
and vote. If a Member attends the meeting and votes in person, his or her proxy
is considered revoked.

                 VOTING SECURITIES AND PRINCIPAL HOLDERS THEREOF

                            VOTING RIGHTS OF MEMBERS

     As of March 22, 2002, there were 8,284,181 Common Shares outstanding.
Members of record of Common Shares shall be entitled to one vote per Common
Share, provided that if and so long as the votes conferred by "Controlled Common
Shares" (as defined below) of any person constitute ten percent (10%) or more of
the votes conferred by the outstanding Common Shares of the Company, each
outstanding Common Share comprised in such Controlled Common Shares shall confer
only a fraction of a vote that would otherwise be applicable according to the
following formula:

                       [(T divided by 10)-1] divided by C

     Where: "T" is the aggregate number of votes conferred by all the
outstanding Common Shares; and "C" is the number of votes conferred by the
Controlled Common Shares of such person.

     "Controlled Common Shares" in reference to any person means:

                  (i)   all Common Shares directly, indirectly or
                        constructively owned by such person within the meaning
                        of Section 958 of the Internal Revenue Code of 1986, as
                        amended, of the United States of America; and

                  (ii)  all Common Shares directly, indirectly or constructively
                        owned by any person or "group" of persons within the
                        meaning of Section 13(d)(3) of the Securities Exchange
                        Act of 1934, as amended, and the rules and regulations
                        promulgated thereunder; provided that this clause
                        (ii) shall not apply to (a) any person (or any group
                        that includes any person) that has been exempted from
                        the provisions of this clause or (b) any person or group
                        that the Board, by the affirmative vote of at least
                        seventy-five percent (75%) of the entire Board, may
                        exempt from the provisions of this clause.

     The limitations set forth above do not apply to any Member which is a
"Byrne Entity" (as defined below) for any matter submitted to the vote of
Members, except with respect to the election of directors. "Byrne Entity" means
any of Mr. Jack Byrne, any foundation or trust established by Messrs.
Jack Byrne, Mark Byrne, Patrick Byrne, and any associate or affiliate of any of
them (or any group of which any of them is a part), as defined under Section
13(d) of the United States Securities Exchange Act of 1934, as amended.

     If, as a result of giving effect to the forgoing provisions or otherwise,
the votes conferred by the Controlled Common Shares of any person would
otherwise represent 10% or more of the votes conferred by all the outstanding
Common Shares, the votes conferred by the Controlled Common Shares of such
person shall be reduced in accordance with the foregoing provisions. Such
process shall be repeated until the votes conferred by the Controlled Common
Shares of each person represent less than 10% of the votes conferred by all
Common Shares.

(a)  Performance shares are payable upon completion of pre-defined business
     goals and are valued based on the market value of Common Shares at the time
     awards are earned. With respect to all of the 2001 performance shares
     awarded to Messrs. Kemp, Staples and Campbell and 50% of the 2001
     performance shares awarded to Messrs. Byrne, Barrette, Gillespie and
     Ritchie, "Target" performance is the attainment of a corporate annualized
     return on equity ("ROE") of 12.1% after tax as measured by the Company's
     growth in its intrinsic business value. With respect to 50% of the 2001
     performance shares awarded to Messrs. Byrne, Barrette and Ritchie, "Target"
     performance is the attainment of an insurance operations trade ratio of
     105% (the "Trade Ratio") on OneBeacon's core insurance operations. With
     respect to 50% of the 2001 performance shares awarded to Mr. Gillespie,
     "Target" performance is the attainment of a return on invested assets of
     100 basis points over the applicable return on the two-year United States
     treasury bill. See "Reports of the Compensation Committees on Executive
     Compensation-Compensation Committee" for additional information concerning
     the 2001 awards of performance shares to the Named Executive Officers which
     includes a discussion of the criteria for "Threshold" and "Maximum"
     determinations.

                               COMPENSATION PLANS

PENSION PLANS. Employees of OneBeacon are eligible to receive retirement
benefits under a qualified defined benefit pension plan sponsored by OneBeacon
(the "Pension Plan"). The Pension Plan provides OneBeacon's employees with
annual retirement income beginning at age 65 equal to the product of (x) the
total number of years of participation in the Pension Plan (but not more than 40
years) and (y) 1.3% of the average annual compensation for the highest
consecutive 60 month period in the 120 month period prior to retirement ("Final
Average Compensation") plus .45% of such Final Average Compensation in excess of
Social Security Covered Compensation as defined by the Internal Revenue Service.

     The Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
and the United States Internal Revenue Code, impose maximum limitations on the
annual amount of pension benefits which may be paid under the Pension Plan. As a
result, OneBeacon also sponsors a non-qualified supplemental retirement plan
(the "Supplemental Pension Plan") which provides additional retirement benefits
to highly-paid employees and their beneficiaries. Retirement benefits provided
under the Supplemental Pension Plan represent the difference between (a) the
benefits which would be payable to such persons under the Pension Plan without
taking into consideration the limitations imposed by ERISA and the Internal
Revenue Code and (b) the maximum annual benefits to which such persons are
entitled under the Pension Plan by reason of such limitations.

     Remuneration covered by the Pension Plan and the Supplemental Pension Plan
includes salary and, to a lesser extent annual bonus. Long-term incentive awards
under the Incentive Plan are excluded from all pension benefits provided by
OneBeacon. Due to the timing of the OneBeacon acquisition, at December 31, 2001,
Messrs. Gillespie, Byrne, Barrette, Ritchie, Staples and Campbell each had only
..6 years of credited service with OneBeacon for purposes of accruing pension
benefits, therefore, their respective accrued pension benefits were
insignificant. Mr. Kemp, as an employee of the Company, is not eligible to
receive pension benefits.

DEFERRED COMPENSATION PLANS. The Named Executive Officers are eligible to
participate in various unfunded, nonqualified plans for the purpose of deferring
current compensation for retirement savings (the "Deferred Compensation Plans").
Pursuant to the Deferred Compensation Plans, participants may defer all or a
portion of qualifying remuneration payable by the Company or OneBeacon which can
be invested in various investment options generally available to the investment
community. Amounts credited to the deferred compensation accounts of such
individuals have been included in the Summary Compensation Table.

OTHER COMPENSATION ARRANGEMENTS

     Pursuant to the Incentive Plan, under some circumstances Options may become
fully exercisable, Restricted Shares may immediately vest and performance shares
may become partially or fully payable. Such circumstances are more fully
described in the Incentive Plan.

     Pursuant to an employment agreement dated December 6, 2000, Mr. Ritchie is
entitled to receive his annual base salary of $300,000 should OneBeacon end his
employment for any reason prior to December 31, 2002.

     Pursuant to an employment agreement dated January 1, 2001, Mr. John
Gillespie is entitled to receive an annual base salary of $400,000, an annual
bonus of up to 200% of his base salary, minimum grants of performance shares,
participation in employee benefit and fringe benefit plans and an indemnity.
Under this agreement, Mr. Gillespie may continue his active involvement with his
investment management business, Prospector, so long as Mr. Gillespie devotes the
requisite time required to fulfill his responsibilities to OneBeacon. The
agreement specifies procedures pursuant to which Prospector's funds have the
ability to invest first in opportunities appropriate for both White Mountains
and such funds. Either party can terminate the employment agreement upon 30 days
notice, and upon termination Mr. Gillespie is entitled to accrued compensation
and a cash payment equal to a pro rated value of his unearned performance share
awards.


                                        12




     Pursuant to revenue sharing agreements, Mr. Gillespie has agreed to pay
White Mountains a portion of the revenues and distributions allocable to him in
connection with his investment management business, in return for White
Mountains agreeing to pay the operational expenses of his investment management
companies. During 2001, White Mountains received a net payment of $504,600 from
Mr. Gillespie under such revenue sharing agreements. In addition, in September
2001, White Mountains entered into a five-year lease at a market-based rate for
a building owned by Mr. Gillespie and trusts for the benefit of members of his
family. At December 31, 2001, White Mountains had $82 million invested in funds
managed by Prospector.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Mr. Clark is Vice Chairman of Lehman. Lehman has, for a number of years,
provided investment banking services to White Mountains. Lehman was the
arranger, the administrative agent and a lender under the $875.0 million credit
facility used to acquire OneBeacon.

     Mr. George Gillespie is a partner at CS&M. CS&M has, for many years,
provided legal services to White Mountains.

     White Mountains owns limited partnership investment interests which are
managed by Mr. John Gillespie. See "Other Compensation Agreements."

     At December 31, 2001, White Mountains had limited partnership investment
interests in High Rise Partners, L.P. White Mountains also owns investments that
are managed by High Rise Capital Management L.P., of which Mr. Zankel is the
senior Managing Member.

     White Mountains believes that the above transactions were on terms that
were reasonable and competitive and, in the case of Lehman, were obtained
through a competitive bid process. White Mountains believes that such
transactions did not serve to impair the independence of any of the parties
involved. Additional transactions of this nature may be expected to take place
in the ordinary course of business in the future.

               REPORTS OF THE COMMITTEES ON EXECUTIVE COMPENSATION

     The Human Resources Committee and the Compensation Committee (collectively,
the "Committees") are comprised entirely of non-employee directors. The
Committees are responsible for developing, administering and monitoring the
executive compensation policies of the Company and OneBeacon. Salary and bonus
compensation for the Named executive Officers is established by the Human
Resources Committee. Share-based compensation (performance shares, Options and
Restricted Shares) is established by the Compensation Committee.

     White Mountains' executive compensation policies are designed with one goal
in mind - maximization of Member value over long periods of time. The Committees
believe that this goal is best pursued by utilising a pay-for-performance
program which serves to attract and retain superior executive talent and provide
management with performance-based incentives to maximize Member value. Through
this compensation program, the Committees seek to maximize Member value by
aligning closely the financial interests of White Mountains' management with
those of its Members.

     The Committees believe that the most appropriate measure of Member value
created (or lost) is the Company's ROE as measured by growth in its intrinsic
value. In determining intrinsic value, the Committees will consider growth in
economic value per share with some attention to growth in tangible book value
per share, market value per share and such other relevant values, as the
Committees may determine, in reaching a balanced conclusion about performance.
This proprietary measure is viewed by management and the directors as being a
conservative measure of the economic value of White Mountains and includes the
cost of all projected compensation awards. The Committees believe that, over
long periods of time, maximizing the Company's ROE will optimize Member returns.


                                        13




     The Committees believe that the performance-based compensation for key
employees should be payable only if the Company achieves truly superior returns
for its Members. Therefore, the target of many of White Mountains'
performance-based compensation programs are directly linked to achievement of an
annualized ROE at least equal to the market yield available from a ten- year
United States Treasury note plus 700 basis points, or currently 12%. The
Committees believe that this return is a challenging target for the Company in
its current form.

     Compensation of White Mountains' management team, including the Named
Executive Officers, consists primarily of three components: base salary, annual
bonus and long-term incentive awards.

HUMAN RESOURCES COMMITTEE

BASE SALARY. Base salary for each Named Executive Officer is established
annually, on or about March 1. When establishing base salaries of the Named
Executive Officers, the Human Resources Committee considers numerous factors
including each Named Executive Officer's qualifications, corporate
responsibilities, performance since their last salary adjustment and, except for
the CEO, the recommendations of the CEO.

ANNUAL BONUS. For 2001 the target annual bonus pool for the Named Executive
Officers was equal to 50% of eligible base salary at a 12.1% annual ROE with no
bonus pool resulting from a ROE of 5.1% or less. When establishing the aggregate
size of the annual bonus pool, the Human Resources Committee considers numerous
factors including performance versus the objectives set forth in the Company's
Annual Business Plan, in particular the Company's financial performance for the
latest fiscal year as measured by ROE, and the recommendations of the CEO

     After establishing the aggregate size of the annual bonus pool, the Human
Resources Committee then considers the distribution of the bonus pool among the
key employees. Each participant's allocation of the pool is determined after
considering numerous factors including individual achievements as compared to
objectives included in the Annual Business Plan, the contribution of such
achievements to the Company's overall financial performance and the
recommendations of the CEO.

     The CEO typically receives an annual bonus equal to the average bonus
percentage received by all officers eligible to participate in the bonus pool.

     For 2001 the Human Resources Committee determined that the financial
results of the Company did not warrant a bonus pool. The principal factor
considered by the Human Resources Committee in making this determination was the
Company's 2001 ROE performance which was determined to be below the threshold of
5.1%, as measured by its change in economic value per Common Share, versus a
12.1% target ROE.

     In light of the completion of the OneBeacon transaction and favorable
investment results attained during 2001, the Human Resources Committee created a
modest special purpose bonus pool for a select group of employees pursuant to
which Messrs. John Gillespie, Staples and Campbell received $110,000, $13,200
and $15,000, respectively. No other Named Executive Officers received a bonus
for 2001.

COMPENSATION COMMITTEE

LONG-TERM INCENTIVE AWARDS. The Incentive Plan provides for granting various
types of share-based incentive awards including Restricted Shares, Options and
performance shares to the Named Executive Officers and certain other key
employees of the Company and its subsidiaries.

     Over the past several years the Company has consistently used performance
shares in its long-term compensation plans. Performance shares are payable only
upon completion of pre-defined business goals and are valued based on the market
value of Common Shares at the time awards are earned.


                                        14




     For 2001, the Compensation Committee determined that awards of Restricted
Shares would be an effective supplement to performance share grants and would
provide an effective means of retention in the form of long-term incentive
compensation to certain key employees.

     The Compensation Committee believes that awards of performance shares are
an attractive method of providing incentives for management to strive to
maximize Member value over the long term. This belief is predicated on the
following factors: (i) such awards are earned over multi-year periods; (ii) such
awards are generally made in the form of Common Shares or derivatives thereof,
which helps to align the interests of management with those of the Company's
Members; and (iii) performance shares are contingent upon the achievement of a
12.1% ROE over the applicable performance period which further aligns the
interests of management and the Company's Members.

     In 2001 Messrs. Kemp, Gillespie, Byrne, Barrette, Ritchie, Staples and
Campbell were granted 2,000; 15,000; 15,000; 15,000; 8,600; 3,000 and 2,500
performance shares, respectively, by the Compensation Committee. The performance
period for such awards began on January 1, 2001 and will continue through
December 31, 2003. With respect to the 2001 performance shares awarded to
Messrs. Kemp, Staples and Campbell, performance is the attainment of a ROE of
12.1% after tax which would result in such performance shares being fully earned
("Target"). At a ROE of 5.1% or less, no such performance shares would be earned
("Threshold") and at a ROE at or above 23%, 200% of such performance shares
would be earned ("Maximum"). With respect to 50% of the 2001 performance shares
awarded to Messrs. Byrne, Barrette and Ritchie, performance is the attainment of
a ROE of 12.1% after tax as defined above. With respect to the remaining 50% of
the 2001 performance shares awarded to these individuals, performance is the
attainment of a OneBeacon core insurance operations Trade Ratio of 105%.
OneBeacon's Trade Ratio is similar to an insurance company's combined ratio but
has been modified to divide general operating expenses by earned premiums rather
than written premiums. With respect to the Trade Ratio aspect of the attainment
goals, at a Trade Ratio of 107% or more, no such performance shares would be
earned ("Threshold") and at a Trade Ratio of 101% or less, 200% of such
performance shares would be earned ("Maximum").

     With respect to 50% of the 2001 performance shares awarded to Mr.
Gillespie, performance is the attainment of a ROE of 12.1% after tax as defined
above. With respect to the remaining 50% of the 2001 performance shares awarded
to Mr. Gillespie, "Target" performance is the attainment of a return on invested
assets of 100 basis points over the applicable return on the applicable two-year
United States treasury bill. With respect to the investment return aspect of the
attainment goals, at an investment return equal to or less than the two-year
treasury, no such performance shares would be earned ("Threshold") and at an
investment return equal to or greater than 200 basis points over the two-year
treasury, 200% of such performance shares would be earned ("Maximum").

     In 2001 the Named Executive Officers received Restricted Shares which vest
approximately two years from the date of grant based on continuous service
throughout such period. Restricted Shares awarded in February 2001 (vesting
December 2002) to Messrs. Kemp, Gillespie, Byrne, Barrette, Ritchie, Staples and
Campbell were 5,000; 0; 0; 3,750; 0; 1,000 and 1,000 shares, respectively.
Restricted Shares awarded in June 2001 (vesting June 2003) to Messrs. Kemp,
Gillespie, Byrne, Barrette, Ritchie, Staples and Campbell were 1,000; 4,000;
25,000; 17,000; 1,000; 3,000 and 3,000 shares, respectively.

     Messrs. Kemp, Gillespie, Byrne, Barrette, Ritchie, Staples and Campbell
had, pursuant to a 1999 grant, 9,000; 0; 0; 6,000; 0; 2,000 and 2,000
performance shares eligible for payout, respectively, subject to the attainment
of a 13% target ROE. During the 1999 to 2001 performance period, the Company
attained a ROE of 28.2% calculated in accordance with the Incentive Plan. In
light of the excellent ROE attained during the performance period, the
Compensation Committee determined that 200% of such performance shares were
fully earned on February 27, 2002. The dollar value of such performance shares
earned are included in the Summary Compensation Table.

                               MEMBER RETURN GRAPH

     The following graph shows the five-year cumulative total return for a
Member who invested $100 in Common Shares (NYSE symbol "WTM") as of the close of
business on December 31, 1996, assuming re-investment of dividends. Cumulative
returns for the five-year period ended December 31, 2001 are also shown for the
Standard & Poor's 500 Stocks (Property & Casualty) Capitalization Weighted Index
("S&P P&C") and the Standard & Poor's 500 Stocks Capitalization Weighted Index
("S&P 500") for comparison.

     As stated herein, White Mountains' various compensation plans are based on
its growth in its economic value which is believed to be a conservative proxy
for its intrinsic business value. The Company's long-term goal is to maximize
its intrinsic business value per Common Share which will, in turn, affect its
market value per Common Share.
