             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") 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, 1998.


2. Contingencies

  The Company is involved regularly, directly or indirectly, in litigation in
the ordinary course of conducting its insurance and reinsurance business.  In
some cases, plaintiffs seek to establish coverage for liability under
environmental protection laws.  While the nature and extent of insurance and
reinsurance coverage for environmental liability has widened since 1980, in
management's judgment, none of these cases, individually or collectively, is
likely to result in judgments for amounts which, net of losses and loss
adjustment expense liabilities previously established and reinsurance
recoverables which management believes are probable of realization, would have a
material effect on the financial position of the Company, although there is no
assurance as to whether or not such losses will materially affect the Company's
results of operations for any period.

4. 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 September 30, 1999, the aggregate exposure on
reinsurance ceded to Lloyd's syndicates for continuing operations, including
estimated reinsurance recoveries for losses incurred but not reported, was about
$75.0 million.  The majority was ceded into Equitas with effect from September
4, 1996.  Equitas is a company with limited liability established by the Lloyd's
syndicates.  Therefore, ultimate recoveries under the reinsurance contracts
ceded into Equitas will be dependent on Equitas being able to fulfil its
commitment to the syndicates.

  Segment profit or loss is measured by income from operations before income
tax.  All inter-segment revenues have been eliminated on consolidation.

  The Company has changed its basis of segmentation from that used in the 1998
Annual Report on Form 10-K.  The four segments reported in the 1998 Form 10-K
were as follows:

    a)  Marine & Aviation;
    b)  Non-Marine;
    c)  Agency; and
    d)  Corporate.

               Management's discussion and analysis of Financial
                      Condition and Results of Operations

  The Company has changed its basis of segmentation from that used last year.
The four reportable segments are Terra Nova, Terra Nova (Bermuda), Terra Nova
Capital and Corifrance.  The segments are strategic business units that operate
in different markets.  Terra Nova and the Lloyd's syndicates in which Terra Nova
Capital participates are based in the London Market.  The London Market is
comprised of Lloyd's and companies with underwriting offices close to Lloyd's.
Terra Nova (Bermuda) operates in the Bermuda Market which consists of both
captive and independent companies.  Corifrance is a French reinsurer
specializing in property reinsurance in the European Market.

  The Company's premiums by segment for the three and nine months ended
September 30, 1999, and 1998, and the combined ratio are set out in the
following table:

Results of Operations

  Gross written premiums increased 24.4% to $156.2 million in the third quarter
of 1999, up from $125.6 million written in the third quarter of 1998.  Gross
written premiums for the nine months were $710.3 million, up 19.7% from $593.4
million written in the same period a year ago.

  Terra Nova's gross written premiums were $32.9 million in the third quarter
compared to $49.1 million in the third quarter of 1998.  Gross written premiums
for the nine months were $240.3 million compared to $271.0 million in the same
period last year.  Terra Nova's premium writings reflect lower premium rates on
most classes of business in which it participates and its exit from marine hull
and energy business in December 1998.

  Terra Nova (Bermuda)'s gross written premiums increased 18.2% to $5.2 million
in the third quarter from $4.4 million last year.  Gross written premiums for
the nine months were $39.7 million compared to $46.6 million in 1998.  The prior
year figure includes $11.9 million of orphan syndicate business.  No orphan
syndicate business has been written during the current year.  Excluding orphan
syndicate business, Terra Nova (Bermuda)'s gross written premiums are up

14.4% on last year. The segment traditionally writes little business in the
third quarter as it writes mainly property reinsurance in the first quarter of
the year.

  Terra Nova Capital's gross written premiums increased by 66.9% to $115.5
million from $69.2 million in the third quarter and by 61.2% to $409.7 million
from $254.2 million in the first nine months.  The rise is due to an increased
participation in the Octavian syndicates from about 60% of capacity in 1998 to
about 77% in 1999 and an increase in premium writings at the Octavian
syndicates.  The increase also reflects higher writings at syndicates 702
(benefiting from the newly opened Australian office and other initiatives put in
place last year), 1227 (expansion of property writings) and 1228 (more overseas
auto business).  The segment has written no orphan syndicate business in the
year so far compared to $16.0 million last year.

  Corifrance writes a large part of its business in the first quarter of each
year.  Gross written premiums in the first nine months of 1999 were $20.6
million compared to $21.5 million in 1998.

  The Company's combined ratio was 109.2% in the first nine months against 98.5%
in the same period of 1998.  Excluding the charge in the second quarter of 1999
associated with the Company's withdrawal from UK private passenger auto, light
aircraft and general aviation businesses, the combined ratio was 101.3%.

  The Company's underwriting results reflect the ongoing effects of price
erosion over the past several years, the late reporting of losses from last
year's hurricanes Georges and Mitch and a significant number of large
catastrophe losses in the United States and the rest of the world.  The third
quarter results included $9.0 million of property losses associated with the
various catastrophes, most significantly, Hurricane Floyd and the earthquakes in
Turkey.

  Net investment income was $23.3 million for the third quarter of 1999 in line
with the same period a year ago.  Net investment income increased to $69.7
million for the first nine months compared to $69.5 million in 1998.  This
reflects the decision taken last year to increase the equity component of the
investment portfolio by $20.0 million consistent with the Company's longer term
focus on growing the book value of the Company.  The average annualized
investment yield was 6.0% and 6.2% in the first nine months of 1999 and 1998,
respectively.

  Realized net capital gains on sales of investments were $22.9 million in the
first nine months of 1999, up from  $12.5 million last year.  The majority of
gains in each period arose from sales of equity securities.

  The net contribution from agency income was $1.6 million for the nine months
compared to $3.1 million last year.  The movement is due to lower profit
commission from the syndicates managed by Octavian and to a change in the stock
option compensation expense estimate for the Octavian Stock Option Plan.  The
Plan provides for the grant of options based on profit commissions received by
Octavian for the 1996 to 2000 Lloyd's underwriting years.  The compensation
expense is calculated using APB No.25 and is dependent on both the share price
at the grant date for each underwriting year and the projected number of options
to be granted.  Any change in these variables gives rise to a change in the
compensation expense.

  Interest expense in 1999 relates to interest on the $100 million 7.0% Senior
Notes issued on May 18, 1998 and interest on the $75 million 7.2% Senior
Notes issued on August 26, 1997.  The interest expense in 1998 related to the
$100 million and $75 million Senior Notes issues and the $100 million 10.75%
Senior Notes extinguished in the second quarter of that year.

  Other expenses increased in 1999 because of a higher level of corporate
activity.

Liquidity and Capital Resources

  The Company's assets consist mainly of the capital stock of UK Holdings and
Terra Nova (Bermuda).  UK Holdings' assets consist mostly of the capital stock
of Terra Nova, Terra Nova Capital and Octavian.  The Company's ability to pay
dividends on its capital stock and to meet its obligations depends on dividends
or other payments from Terra Nova, Terra Nova (Bermuda), Terra Nova Capital,
Octavian and Corifrance.  Dividend and other payments by Terra Nova, Terra Nova
Capital and Octavian are subject to restrictions under UK law.  Similarly,
dividend and other payments by Terra Nova (Bermuda) and Corifrance are subject
to restrictions under Bermudian law and French law, respectively.

  The sources of funds for the Company's subsidiaries consist mostly of net
premiums, investment income and proceeds from sales and redemptions of
investments.  The funds are used to pay claims and operating expenses and to buy
investments, largely fixed income securities.

  For the nine months ended September 30, 1999, the cashflow provided by
operating activities of the Company was $10.8 million compared to $11.7 million
in 1998.

  Shareholders' equity of the Company declined to $526.0 million at September
30, 1999, from $570.9 million at year end 1998 reflecting the decline in market
value of the Company's investment portfolio and share repurchases, partly offset
by growth in retained earnings.  Book value per share was $20.74 at September
30, 1999, compared to $22.51 at year end 1998.

  Total investments and cash were $1,497.3 million at September 30, 1999.  At
September 30, 1999, 87.8%, 6.4% and 5.8% of total investments and cash were held
in fixed maturities, common stocks and cash and cash equivalents, respectively.
At September 30, 1999, around 93% of the Company's fixed income investments were
rated "A" or better by Moody's or S&P.  The Company's investment portfolio
earned interest and dividend income, net of investment management fees, of 6.0%
and 6.2% in the nine months ended September 30, 1999, and 1998, respectively.
The Company's realized investment gains were $29.6 million and $15.9 million in
the nine months ended September 30, 1999, and 1998, respectively.

  On August 5, 1999, the Company announced that it had received an unsolicited
merger proposal and that the Board of Directors had engaged Donaldson, Lufkin
and Jenrette to assist the Company in conducting a review of its strategic
alternatives, including a possible business combination.

  On August 16, 1999, Markel Corporation ("Markel") and the Company announced
that they had signed  an agreement providing for Markel's acquisition of the
Company for cash and stock valued at $905 million, or $34.00 per share, based on
the closing price of Markel's stock on August 13, 1999.  In addition, Markel
would assume $175 million of the Company's debt.  The transaction, which is
subject to approval by the shareholders of both companies, the receipt of
necessary regulatory approvals and other customary closing conditions, is
expected to be completed early in 2000.

  Terra Nova Capital's participation in the Lloyd's Capacity Auctions for the
2000 underwriting year resulted in the acquisition of additional capacity in the
syndicates managed by Octavian.  This will bring the Company's share of
aggregate capacity on the Octavian syndicates to about 90% for the 2000
underwriting year, up from about 77% for the 1999 underwriting year.

  Certain information included here is based on management's estimates,
assumptions and projections.  Important factors that could cause actual results
to differ materially from those estimated by management include, among other
things, an unexpected increase in competition, unfavorable government
regulation, the pricing environment and other industry developments.

Foreign Currency

  The Company's assets, liabilities, revenues and expenses, except for most
corporate overheads which are paid in British pounds, are chiefly in U.S.
dollars.  Therefore, the Company's principal functional currency is the U.S.
dollar.  Certain other net translation adjustments are shown as a separate item
of accumulated other comprehensive income.


The Euro

  On January 1, 1999, the Economic and Monetary Union ("EMU") and a new
currency, the "euro", were adopted by eleven of the fifteen member states of the
European Union ("EU").  Other member states, including the United Kingdom,
currently remain outside the EMU, but may join in the future.  Today, Corifrance
and the Brussels branch of Terra Nova are the Company's only operations in EMU
countries.

  When the eleven participating EMU countries adopted the euro as their national
currency, the European Central Bank (ECB) established a fixed conversion rate
between each participant's existing currency and the euro as from that date.
The euro is now traded on foreign currency exchanges and fluctuates in value
against currencies of non-participating countries.  The euro can be used for
non-cash transactions throughout the three year transition period which ends on
December 31, 2001.  On January 1, 2002, the ECB will begin to issue bills and
coins denominated in euro for use in cash transactions.

  The Company identified relevant issues and established a strategy to deal with
each phase of the euro's implementation.  The Company has the capability to
process and account for current transactions in the euro, and as needs are
identified, will modify its information technology and other systems in response
to changed or expanded exposures to euro transactions.

  The competitive impact of the euro is not expected to be significant because
less than 10% of the Company's business is conducted within EMU member states.
Management believes that future costs of modifying information systems software
will not be material to the Company's results, operations, financial condition
or liquidity.


Year 2000

General

  The Year 2000 issue arises from the fact that historically many computers and
computer programs used two digits rather than four to represent the year portion
of a date.  The faulty interpretation or the misinterpretation of these two
digits could result in system failure or miscalculation causing disruption to
business processes.

  The Year 2000 date change problem is widely recognized as the biggest single
issue to have faced the information technology ("IT") industry.  Its impact is
likely to extend into all areas of business and commerce.  Therefore, the
Company is addressing Year 2000 as both an IT issue and a business issue.  The
Company has established a Year 2000 Project team composed of representatives
from all IT and business areas in order to ensure a co-ordinated approach.  The
Project team reports directly to senior management who, in turn, report
regularly to the Board of Directors on the status of the Company's Year 2000
compliance.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

The Company's State of Readiness

  The Company has divided the Year 2000 Project into three major areas of focus:
IT, underwriting and third parties.  Each section addresses unique risks, but
shares a common approach to the Project, which includes five phases: (1)
assessing the nature and scope of the Company's exposure to the Year 2000 issue;
(2) identifying the business critical areas of exposure; (3) developing
solutions for Year 2000-related problems; (4) testing the solutions; and (5)
implementing the solutions.  Business critical systems were defined as those
that could have a material impact on the financial condition and results of
operations of the Company should they malfunction or fail.

  IT
  --
  The Company initiated the IT section of the Year 2000 Project in March 1997
with the objective of bringing all business critical systems into Year 2000
compliance by September 30, 1998 and all other systems into compliance by
December 31, 1998.  These key milestones have been met.  Market testing with the
main processing bureaus, the London Processing Centre, the Lloyd's Policy
Signing Office and the Lloyd's Claims Office, has also been completed
successfully.  Internal certification on compliance has been received from
Lloyd's.

  The assessment phase for the IT section of the Project consisted of an
inventory and high level analysis of all hardware, software and embedded
systems.  Embedded systems include non-IT items such as facsimile machines,
photocopiers and elevators.  As a result of the assessment phase, the Company
identified five business critical systems.  All five were judged compliant by
December 31, 1998, following completion of testing and implementation work.

  Compliance statements for the Company's telephone systems have been received
and the necessary upgrades have been implemented.  In addition, a testing
program has been commissioned to validate the manufacturers' statements.

  Other internally-supported software not identified as business critical was
judged compliant by December 31, 1998, after testing and implementation work.
Externally supported packages and services were assessed.  All suppliers and
manufacturers were contacted for their compliance status.  Where possible, all
essential packages have been tested and judged compliant.

  Remediation of non-business critical systems with embedded chips has been
challenging.  Work has targeted systems within the Company's control.
Developers of old systems have been reluctant to reply to questions concerning
their Year 2000 compliance status, or are no longer trading.  After assessing
this area of the Project for criticality, the Project team determined that only
a few systems were at risk.  Most of these are now considered to be compliant.
There are no outstanding systems that would result in a significant negative
impact on the Company's operations in the event of failure.

  An IT contingency plan, covering all aspects of IT, has been developed in line
with the Lloyd's timescale of  June 30, 1999.  This plan has been designed to
offer a workable alternative in event of failure of a business critical system.
The IT contingency plan has been incorporated into the Company's Year 2000
contingency plan discussed below.

  Underwriting
  ------------
  The Underwriting section of the Project is managed by a committee comprised of
senior representatives from the Company's major underwriting units and support
units, covering a broad spectrum of business classes.  The committee is: (1) co-
ordinating and reviewing the evaluation of the Company's current and ongoing
underwriting exposure to the Year 2000 and other date-related issues; (2)
developing and producing relevant Company underwriting guidelines and monitoring
procedures, where practicable; (3) identifying business opportunities; and

                      CONDITION AND RESULTS OF OPERATIONS

(4) communicating and raising awareness of date-related underwriting issues
within the Company.  Among its responsibilities, the committee discusses and
disseminates information, research and policy language about the Year 2000
issue.  A central database for this information has been established and made
accessible by all Company employees.

  By June 30, 1999, the Company had completed an initial assessment of risks
already written.  This initial assessment has formed the basis for more detailed
ongoing reviews.  At Terra Nova, the in-force portfolio of insurance and
reinsurance contracts was broken down into those risks that currently provide no
cover beyond December 31, 1999, those that might provide cover beyond December
31, 1999 (by virtue of run-off provisions or extended reporting clauses) and
those risks that run beyond the millennium.  A matrix coding system was
developed to numerically quantify the class exposure and effect of the
underwriting action taken at the insurance or reinsurance level.  The matrix is
applied on a risk by risk basis.  The matrix multiplies a "class exposure"
coding by an "underwriting action" coding to give a geometric weighting.  This
geometric weighting, combined with the potential in-force analysis, and overlaid
by "likelihood of loss factors", enables a calculation to be made of Terra
Nova's probable maximum loss ("PML").  To support the matrix, a detailed
commentary was prepared by each class underwriter of the potential exposure on a
class by class basis, together with the current underwriting approach, based on
individual judgment and experience.  This work was reviewed by the underwriting
committee and the senior underwriter of each underwriting unit for commonality
of approach.  Terra Nova (Bermuda) is applying the matrix coding system in the
same way as Terra Nova.

  Remediation work within the Underwriting section of the Project is ongoing.
The described underwriting approach is regularly monitored and re-evaluated with
reference to external factors and market position.  Exclusionary contract
language is being used where it is considered appropriate.  Equally, the method
of calculating the PML, the weightings applied for the individual factors and
likelihood of loss factors, are subject to review and revision, as considered
necessary.  At September 30, 1999,  management believes the PML reflects a
reasonable level of risk for contracts currently in force.  All new business
opportunities are assessed using the PML calculation.  No new contracts are
written where the Year 2000 exposure is unsatisfactory.

  The Octavian syndicates are also represented on the underwriting committee.
However, the senior underwriters on the Octavian syndicates have adopted a
different approach from that of their colleagues at Terra Nova, reflecting the
different regulatory environment in which they operate.  The syndicate
underwriters have analyzed the Year 2000 exposure on each class of business that
they write.  They have then drawn up a course of action for dealing with the
exposure, using the results of their analysis.  The regulatory department at
Lloyd's requests detailed Year 2000 returns from each syndicate.  This is to aid
the Corporation of Lloyd's' analysis of whether each syndicate is taking
appropriate action to address the issue.

  Overall, management believes reliance on the combined experience of the
Company's underwriters who contribute to the ongoing assessment has enabled the
Company to make prudent judgments about exposures and to react accordingly.

  Third Parties
  -------------
  The Third Parties section of the Year 2000 Project includes identifying
critical suppliers, customers and trading partners who deal directly with the
Company and discovering their plans and progress in addressing Year 2000 issues.
The Company receives most of its underwriting data from bureaus, most notably,
the London Processing Centre and Lloyd's.  Market testing has been performed to
insure continuous and reliable connectivity to, and the ongoing provision of
effective services from, these organizations and has been successfully
completed.

  The Company provides IT services to third party customers.  The related IT
systems have been assessed, remedied, tested and re-implemented.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

  Material trading partners at all business levels have been contacted and asked
to respond with an assessment of the Year 2000 compliance status of their own
businesses.  The responses from trading partners have been considered when
developing the Year 2000 contingency plan.

Year 2000 Contingency Plan

  The Company has developed a contingency plan to mitigate the effect of
business disruption caused by Year 2000 problems.  Each of the Company's
individual business units has reviewed the risk they face and completed a year
2000 risk register.  The register records material risks, their impact and
importance.  An action plan has also been developed by the business units to
respond to the occurrence of each risk event.

  These registers have been reviewed centrally and compiled into a single
Company-wide risk register.  The register documents responsibility for ensuring
that adequate plans are in place and, if necessary, acted on.

Costs

  The total cost of the Year 2000 Project is not expected to be material to the
Company's financial position.  The estimated total cost of analyzing and
implementing required modifications to bring the Company to Year 2000 compliance
is $3.0 million, which is being funded from operating cash flows.  The Company
chiefly used internal human resources for work on the Year 2000 Project. The
total amount spent on the Project through September 30, 1999, was $2.9 million
of which $2.7 million related to the cost to repair or replace software and
resolve related hardware problems and $0.2 million related to the cost of
identifying and communicating with third parties. The estimated future cost of
completing the Year 2000 Project is $0.1 million.

Risks

  From an IT perspective, the Year 2000 risks have been reduced significantly by
bringing business critical systems into compliance.  Therefore, the ability of
the Company to trade through the Year 2000 should not be materially impaired.
The Company's reliance on compliance adequacy of outside suppliers and trading
partners can only be addressed through questionnaires and compliance statements.
Even with seemingly thorough third parties' responses, the Company cannot
guarantee their Year 2000 readiness.  The inability of such third parties to
complete their Year 2000 remediation could materially affect the Company.

  From an underwriting perspective, the Company has conducted a comprehensive
review of its underwriting guidelines with particular emphasis on the Year 2000
exposures. It is the Company's position that Year 2000 exposures are not
fortuitous losses and thus are not covered under insurance policies even without
specific exclusions. However, in certain sectors of the Company where there may
be a perceived exposure to the Year 2000 claims, the Company has bought
reinsurance to protect itself. For these reasons,the Company believes that its
exposure to Year 2000 claims will not be material. However, as was the case with
environmental exposures, changing social and legal trends may create unintended
coverage for exposures by reinterpreting insurance contracts and exclusions. It
is impossible to predict what, if any, exposure insurance companies may
ultimately have for Year 2000 claims whether coverage for the issue is
specifically excluded or included.

  While there remains a degree of uncertainty about the Year 2000 readiness of
third party suppliers, customers and trading partners, the Company believes it
has taken all reasonable steps to ensure the consequences of Year 2000 failure
will not have a material impact on its future results of operations, liquidity
or financial condition.


Dividend Policy

  On February 10, 1999, the Company declared a dividend of $0.06 per share
payable on March 26, 1999 to shareholders of record as of March 5, 1999.

  On May 5, 1999, the Company declared a dividend of $0.06 per share payable on
June 25, 1999, to shareholders of record as of June 4, 1999.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

  On August 5, 1999, the Company declared a dividend of $0.06 per share payable
on September 27, 1999, to shareholders of record as of September 3, 1999.

  On November 3, 1999, the Company declared a dividend of $0.06 per share
payable on December 27, 1999, to shareholders of record as of December 3, 1999.

  The declaration and payment of dividends is at the discretion of the Board of
Directors of the Company and will depend on the Company's results of operations,
the financial position and capital requirements of the Company's operating
subsidiaries, general business conditions, legal, tax and regulatory
restrictions on the payment of dividends and other factors the Board of
Directors of the Company views relevant.  While the Company is not itself
subject to any contractual restrictions or significant legal prohibitions on
dividend payments, the Company's subsidiaries are subject to regulatory and
legal constraints on their respective abilities to pay dividends.  Therefore,
there is no assurance that dividends will be declared or paid in the future.


Quantitative and Qualitative Disclosure about Market Risk

  The Company presented a discussion about its risk management activities in its
Form 10-K for the year ended December 31, 1998.  The Company believes there have
been no material changes regarding its market risks during the nine months ended
September 30, 1999.
