                       TERRA NOVA (BERMUDA) HOLDINGS LTD.
                                AND SUBSIDIARIES

             Notes to the Interim Consolidated Financial Statements
                                  (Unaudited)

1. Basis of Presentation

  The accompanying interim consolidated financial statements ("Statements")
present information about Terra Nova (Bermuda) Holdings Ltd. (the "Company"), a
wholly owned subsidiary of Markel Corporation, and have been prepared on the
basis of United States generally accepted accounting principles.  All material
intercompany transactions and balances have been eliminated.  In the opinion of
management, these unaudited Statements reflect all adjustments (consisting of
normal recurring accruals) necessary for a fair presentation of the financial
position, results of operations and cash flows of the Company.  The results of
operations for interim periods do not necessarily indicate the results to be
expected for the full year.

  These Statements should be read with the audited consolidated financial
statements as of December 31, 2000.


2. Contingencies

  On January 31, 2001, the Company received notice of a lawsuit filed in the
United States District Court for the Southern District of New York against Terra
Nova by Palladium Insurance Limited and Bank of America, N.A. seeking
approximately $27 million plus exemplary damages in connection with alleged
reinsurance agreements.  The Company believes it has numerous defenses to these
claims, including the defense that the alleged reinsurance agreements were not
valid.  The Company intends to vigorously defend this matter, however, it cannot
predict the outcome at this time.

  The Company has other contingencies that arise in the normal conduct of its
operations.  In the opinion of management, the resolution of these contingencies
are not expected to have a material impact on the Company's financial condition
or results of operations.


3. Reinsurance

  In the ordinary course of business,  the Company cedes reinsurance to other
insurance companies.  Ceded reinsurance arrangements provide greater
diversification of business and limit the net loss potential arising from large
risks.  Certain of these arrangements consist of excess of loss contracts which
protect against losses over stipulated amounts.  Reinsurance is effected under
reinsurance treaties and by negotiation on individual risks.

  The Company cedes reinsurance to and assumes reinsurance from Lloyd's of
London ("Lloyd's") syndicates.  At March 31, 2001, the aggregate exposure on
reinsurance ceded to Lloyd's syndicates for continuing operations, including
estimated reinsurance recoveries for losses incurred but not reported, was
approximately $177 million.

  On January 29, 2001, Reliance Insurance Company entered into an order of
supervision with the Pennsylvania Insurance Department under which its business
and operations will be monitored and reviewed by the Department.  At March 31,
2001, and December 31, 2000, Reliance Insurance Company and its affiliates
(Reliance Insurance Group) owed the Company approximately $33.4 million in
reinsurance recoverables for paid and unpaid losses.  These balances were
considered in the normal course of assessing the collectability of reinsurance
recoverables.  The Company believes this matter will not have a material impact
on its financial condition or result of operations.

4.  Business Segments

  The Company has three operating segments: the London Company Market, the
Lloyd's Market and Investing.  All investing activities are included in the
Investing operating segment.  Discontinued programs and non-strategic insurance
subsidiaries are included in Other for purposes of segment reporting.

  The Company considers many factors including the nature of the underwriting
units' insurance products, production sources, distribution strategies and
regulatory environment in determining how to aggregate operating segments.

profit for the Investing operating segment is measured by net investment income
and realized net gains or losses.

  The Company does not allocate assets to the operating divisions for management
reporting purposes.  The total investment portfolio and cash and cash
equivalents are allocated to the Investing operating segment.  The Company does
not allocate capital expenditure for long-lived assets to any of its operating
segments for management reporting purposes.

6.  Derivatives

  The Company adopted Financial Accounting Standards Board Statement of
Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative
Instruments and Hedging Activities, as amended by SFAS No. 137 and 138,
effective January 1, 2001.  The standard requires that all derivatives be
recorded as an asset or liability, at estimated fair value, regardless of the
purpose or intent for holding the derivative.  If a derivative does not qualify
as a hedge under SFAS No. 133, all gains or losses from the change in the
derivative's estimated fair value are recognized in earnings.  The gains or
losses from the change in estimated fair value of derivatives that qualify as
hedges under SFAS No. 133 are recognized in earnings or other comprehensive
income depending on the type of hedge relationship.

  The Company has entered into forward foreign exchange contracts which have
been designated as hedges of net investments in foreign operations.  The
contracts are recorded at fair value, with the change in fair value recorded in
cumulative translation adjustments (CTA) to the extent the change is equal to or
less than the offsetting adjustment recorded in CTA that arose by translating
the hedged foreign operation's financial statements to the Company's reporting
currency.   To the extent the change in the fair value of the forward contracts
is greater than the adjustment of the net investment, it would be included in
earnings.

  At March 31, 2001, the Company had entered into forward foreign exchange
contracts with an aggregate notional amount of $81.5 million to buy United

Safe Harbor Statement

  This is a Safe Harbor Statement under the Private Securities Litigation Reform
Act of 1995.  Any written or oral statements made by or on behalf of the Company
reflect the Company's current views with respect to future events and financial
performance.  These forward-looking statements are subject to uncertainties and
inherent risks that could cause actual results to differ materially from those
contained in any forward-looking statement.

  The Company has identified certain factors that could cause actual plans or
results to differ substantially from those included in any forward-looking
statements.  These risk factors include, but are not limited to, the following:
(i) uncertainties and changes in government policy and law (both statute and
case law) with respect to the Company, its brokers or customers (for example,
the Company is subjected to taxation in an additional jurisdiction, there is a
change in the way insurance contracts are interpreted by a court of law, etc.);
(ii) uncertainties and changes in regulatory policy and law (for example, the
Company is subjected to insurance regulation in an additional jurisdiction);
(iii) the occurrence of man-made or natural catastrophic events with a frequency
or severity exceeding the estimates of the Company; (iv) the uncertainties of
the reserving process; (v) changing rates of inflation and other economic
conditions; (vi) losses due to foreign currency exchange rate fluctuations;
(vii) ability to collect reinsurance recoverables; (viii) changes in the
availability, cost or quality of reinsurance; (ix) developments in global
financial markets that could affect the Company's investment portfolio; (x)
risks associated with the introduction of new products and services; (xi)
increased competition on the basis of pricing, capacity, coverage terms or other
factors; (xii) changes in the distribution or placement of risks due to
increased consolidation of insurance and reinsurance brokers; (xiii) the impact
of Year 2000 related issues on the Company's underwriting exposures;  (xiv) the
effects of mergers, acquisitions and divestitures; (xv) ineffectiveness or
obsolescence of the Company's business strategy due to changes in present or
future market conditions; (xvi) the legal environment and social trends; and
(xvii) the loss of the services of any of the  Company's executive officers and
significant changes in personnel.

  The Company undertakes no obligation to publicly update or revise any forward-
looking statement, whether as a result of new information, future events or
otherwise.  Readers are cautioned not to place undue reliance on any forward-
looking statements, which speak only as at their dates.

  The Company is currently working to increase its focus on underwriting
profitability in continuing programs.  These initiatives may lead to the
repricing or discontinuance of poor performing lines of business, reorganization
of business units to achieve operating efficiencies and a review of reinsurance
programs and exposures. These initiatives could lead to further charges and
expense for the Company.  The Company's premium growth, underwriting and
investment results have been and will continue to be potentially and materially
affected by the above factors.

                MANAGEMENT'S DISCUSSION OF RESULTS OF OPERATIONS

Business Operations

  The London Company Market consists of the operations of Terra Nova.  The
Lloyd's Market includes Markel Capital, which is the corporate capital provider
for four Lloyd's syndicates for the 2001 year of account managed by Markel
Syndicate Management. Non-Marine Syndicate 702, Marine Syndicate 1009, the
continuing lines of Motor Syndicate 1228 and Non-Marine Syndicate 1239 are
included in the Lloyd's Market segment.  Discontinued syndicates, the
discontinued lines of Motor Syndicate 1228, Terra Nova (Bermuda) and Corifrance
are included in Other for segment reporting purposes as they are either
discontinued lines of business or non-strategic businesses.  Markel
International's operating units write specialty property, casualty, marine and
aviation insurance and reinsurance on a worldwide basis.  The majority of Markel
International's business comes from the United Kingdom and the United States.

  Following, is a comparison of gross premium volume by significant underwriting
area:



       Gross Premium Volume                    Three months ended March 31,
                                                  2001                2000

London Company Market                           $ 55,762            $103,712
Lloyd's Market                                   178,963             112,897
Other                                             15,902              73,258
- ----------------------------------------------------------------------------
Total                                           $250,627            $289,867
- ----------------------------------------------------------------------------



  Gross written premiums decreased 13.5% to $250.6 million in the first quarter
of 2001 from $289.9 million written in the first quarter of 2000.  The decrease
is primarily a result of:

(a)  A 46.2% decrease in gross written premiums at the London Company Market to
     $55.8 million in the first quarter of 2001 from $103.7 million in the first
     quarter of 2000.  The decrease was predominantly the result of Terra Nova
     reducing its property writings by 55.8% in the three months to March 31,
     2001, compared to 2000.  The decrease on the property account arose
     primarily on the property catastrophe, risk excess and pro rata business
     due to the non-renewal of unprofitable accounts. In addition, in line with
     the Company's philosophy to focus on underwriting profitability, writings
     on the casualty account (professional indemnity business) and marine
     account have also reduced in 2001 compared to 2000.

(b)  Significant decreases in gross written premiums in discontinued lines due
     to the closure of Terra Nova (Bermuda) on April 2, 2000, and the decision
     to cease underwriting at Marine Syndicate 329, Non Marine Syndicate 1227
     and the discontinued lines of Motor Syndicate 1228 in the third quarter of
     2000. The majority of discontinued premium income in the first quarter of
     2001 arose at Corifrance which is considered as non-strategic and is
     therefore included within Other for segment reporting purposes.

                MANAGEMENT'S DISCUSSION OF RESULTS OF OPERATIONS

Business Operations (Continued)

(c)  These decreases have been partially offset by a 58.5% increase in gross
     written premiums at the Lloyd's Market for the three months to March 31,
     2001.  The increase is primarily due to Markel Capital increasing its
     participation on the continuing syndicates to 100% in 2001 compared to
     approximately 87% in 2000 and increased writings at Non Marine Syndicate
     702, Marine and Aviation Syndicate 1009 and Non Marine Syndicate 1239.
     This increase is partially offset by lower writings at Motor Syndicate
     1228.

   Net written premiums decreased 23.7% to $184.3 million in the first quarter
of 2001 from $241.4 million in the first quarter of 2000.  This reflects the
fall in gross written premiums as well as a decrease in retention rates to 74%
in the first quarter of 2001 compared to 83% in the first quarter of 2000. In
2000, a large proportion of reinsurance was purchased in the second quarter so
as to avoid coverage disputes with respect to Year 2000 issues. In 2001, the
majority of these policies incepted in the first quarter.

   Net earned premiums decreased by 11.5% in the first quarter of 2001 to $137.0
million from $154.7 million in 2000. The decrease reflects the decreased
writings in 2001.

   Following, is a comparison of selected data from the Company's operations:



                                                        Three months ended March 31,

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


   The underwriting loss was $22.3 million in the first quarter of 2001 compared
to $100.6 million in 2000 resulting in an improvement in the combined ratio to
116% in 2001 from 165% in 2000.

   The improvement in 2001 reflects the underwriting discipline adopted since
the acquisition by Markel Corporation on March 24, 2000 and the impact as
premiums written since acquisition are earned.  In addition, the underwriting
loss from discontinued and non-strategic lines decreased to $9.2 million in the
first quarter of 2001 compared to a loss of $27.0 million in 2000 due to lower
unfavorable prior year reserve development.

   The underwriting loss in the first quarter of 2000 was primarily the result
of inadequate pricing, poor underwriting controls on the discontinued lines and
portions of the continuing programs and included non-recurring transaction
related expenses of $58.6 million.

   The Company will continue to review claims and reinsurance experience, and
although loss and bad debt reserves are believed to be adequate, adverse
experience is possible and could result in reserve increases in the future.

                MANAGEMENT'S DISCUSSION OF RESULTS OF OPERATIONS

Business Operations (Continued)

  The Company had a pre-tax loss of $2.7 million in the first three months of
2001 compared to a pre-tax loss of $105.1 million in 2000. The pre-tax loss of
$2.7 million in 2001 was primarily a result of the underwriting loss, being
partially offset by investment income and realized investment gains.  The pre-
tax loss of $105.1 million in 2000 was primarily a result of the $100.6 million
underwriting loss and merger expenses of $18.4 million being partially offset by
investment income.

  The post-tax income was $0.4 million in the first quarter of 2001 compared to
a post-tax loss of $82.9 million in 2000.  The tax benefit as a percentage of
loss from operations before tax was 115.9% in the first quarter of 2001 compared
to 21.1% in 2000.  This was due to losses generated from the Company's UK
operations which give rise to tax credits, off-set by income generated in
Bermuda which is not subject to tax.

  Shareholder's equity increased by 0.8% to $281.0 million at March 31, 2001,
compared to $278.7 million at December 31, 2000.  The increase of $2.3 million
was primarily due to the net profit of $0.4 million and unrealized appreciation
of investments after tax of $8.4 million, partially offset by currency
translation adjustments of $6.6 million.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

   Market risk is the risk of economic losses due to adverse changes in the
estimated fair value of a financial instrument as the result of changes in
equity prices, interest rates, foreign exchange rates and commodity prices.  The
Company's consolidated balance sheets include assets and liabilities whose
estimated fair values are subject to market risk.  The primary market risks to
the Company are equity price risk associated with investments in equity
securities, interest rate risk associated with investments in fixed maturities
and foreign exchange risk.   The Company has no material commodity risk.

   The Company's market risks at March 31, 2001 have not materially changed from
those identified at December 31, 2000.
