                        REPORTS FOURTH QUARTER RESULTS
                        ------------------------------


Hamilton, Bermuda, February 18, 2000 - Terra Nova (Bermuda) Holdings Ltd. (NYSE-
TNA) today reported unaudited operating losses for the fourth quarter and full
year ended December 31, 1999.  The operating losses reflect substantial
insurance losses from natural catastrophes and the losses and costs associated
with closing and merging certain business units. As a result of these losses and
the decline in investment valuations in the first three quarters of the year,
Terra Nova's book value per share declined to $17.50 from $22.51 at December 31,
1998.

In focusing on the year to date results, John J. Dwyer, Terra Nova's Chairman,
commented, "In reviewing the year as a whole our underwriting results have been
determined by two significant events.  First, 1999 was the worst year for
international catastrophe losses in recent history.  Terra Nova's share of these
catastrophes and large losses for the year was $59 million, including $42
million of catastrophe losses in the fourth quarter.   Secondly, we were active
in closing certain businesses, such as our decisions to exit company market
marine hull and energy business at the beginning of the year and to exit high
street motor business in the second quarter, and in re-structuring and combining
others, such as the merger of our aviation syndicate 959 into our marine
syndicate 1009.  Underwriting losses in 1999 from businesses we are not
continuing in 2000, together with associated closure costs, totaled $122 million
in the year.  Notwithstanding a very disappointing year, with the restructuring
behind us and assuming a more normal level of catastrophes, the Company is well
positioned to take advantage of improvements in pricing that we expect to see
continuing throughout 2000.

"Turning to the quarter, our underwriting loss is the result of three key
factors: significant catastrophe losses; additional reinsurance costs incurred
in protecting the aviation and satellite business written by our Lloyd's
Syndicate 959; and late reporting of claims relating to certain property loss
events.   In the final week of the year, two intense windstorms caused severe
damage to heavily industrialized and populated areas of Western Europe.  These
storms, Lothar and


Martin, have been described as the worst in 400 years and are expected to
generate heavy losses for the insurance industry. Current industry estimates are
in the range of $5 billion to $6 billion. The storms produced the most severe
damage in France, Switzerland and Germany, countries in which Terra Nova has
important client relationships and provides related insurance and reinsurance
coverage. We expect net claims from these two storms to be approximately $30
million. Earlier in December, another severe, but unrelated storm, Anatol, hit
Denmark causing substantial property damage. We expect Terra Nova's net claims
from Anatol and from hurricanes Jose and Lenny in the Caribbean to be
approximately $12 million.

"Secondly, we took a charge in the quarter to recognize the cost of buying
additional reinsurance protection for the aviation and satellite business
written by our Lloyd's Syndicate 959, which was merged into Syndicate 1009 for
the 2000 underwriting year.  Lastly, we experienced adverse development on
claims relating to certain 1999 property loss events, in large part because of
late reported losses on international proportional treaties.

"Our operational transition in contemplation of the Markel merger is proceeding
very well as we prepare for the special shareholder meetings on March 16, and
the closing scheduled for March 24, 2000," Dwyer concluded.

Fourth quarter operating losses per diluted share were $3.01 compared to
earnings of $0.72 in 1998.  For the full year, operating losses were $2.13 per
diluted share compared to earnings of $2.72 per diluted share in 1998.

The net loss, which includes net realized investment gains, was $81.2 million in
the fourth quarter compared to net income of $19.2 million in the same period a
year ago.  The net loss per diluted share was $3.09 in the quarter compared to
net income of $0.74 per diluted share in 1998.  The net loss for the full year
was $35.0 million, or $1.34 per diluted share, compared to net income of $72.4
million, or $2.77 per diluted share, in the same period a year ago.  Net
realized after-tax investment losses in the fourth quarter were $2.2 million,
compared to gains of $0.6 million in the same quarter last year.  Net realized
after-tax investment gains for the full year were $20.7 million, up from $13.1
million in 1998.

                                       2


Gross written premiums were $154.7 million in the fourth quarter, compared to
$166.0 million written in the fourth quarter of 1998.  The decline in gross
written premiums arises primarily from the Company writing no Lloyd's orphan
syndicate business in the fourth quarter of 1999 compared to $39.7 million in
the fourth quarter of 1998.  Gross written premiums for the full year were
$864.9 million, up 13.9% from $759.4 million written a year ago.  The increase
in gross written premiums in 1999 is largely attributable to Terra Nova's
increased participation in the Octavian syndicates from 60% in 1998 to
approximately 77% in 1999.

Net written premiums in the fourth quarter were $62.3 million, compared to
$139.4 million in last year's fourth quarter.  The decline in net written
premiums reflects the absence of orphan syndicate business in 1999 compared to
1998, additional aviation and satellite reinsurance costs in 1999 and additional
reinsurance costs arising from the high level of catastrophe losses in the
quarter.  Net written premiums for the full year were $618.4 million in 1999,
compared to $646.2 million a year ago.

The combined ratio for the fourth quarter and full year ended December 31, 1999,
was 203.2% and 129.4%, respectively, compared to a combined ratio of 99.3% and
98.8% in the same periods of 1998.

Net investment income was up 1.7% to $24.1 million for the fourth quarter of
1999 from $23.7 million in the same period a year ago.  Net investment income
increased to $93.8 million for the full year compared to $93.3 million in 1998.

Total assets at December 31, 1999, were $2.6 billion compared to $2.5 billion at
year end 1998.  Shareholders' equity was $444.0 million at December 31, 1999,
compared to $570.9 million at year end 1998, reflecting the operating loss and
an after tax decline of $63.6 million in the market value of the Company's
investment portfolio.  Book value per share was $17.50 at December 31, 1999,
compared to $22.51 at year end 1998.
