                MARKEL REPORTS RECORD INCOME FROM CORE OPERATIONS

FOR IMMEDIATE RELEASE                                CONTACT:  DARRELL D. MARTIN
                                                     DIRECT LINE:  804-965-1635

         Richmond,  VA,  February  1, 2000 --- (NYSE - MKL)  Markel  Corporation
announced  record  earnings from core operations for the year ended December 31,
1999,  while net income  decreased  to $7.20 per  diluted  share from $10.17 per
diluted share in 1998.  The decrease in 1999 net income was primarily the result
of realized  investment losses.  Alan I. Kirshner,  Chairman and Chief Executive
Officer,  commented,  "We wish to thank our  associates  for their hard work and
outstanding  accomplishments  in 1999.  Our  core  underwriting  units  produced
exceptional  underwriting  results which  exceeded  their 1999  business  plans,
however  the year  presented  a  difficult  environment  for our  value-oriented
investment  philosophy.  We have  completed the  integration of Gryphon into our
organization,  and we believe the pending  Terra Nova  acquisition  will provide
additional opportunities to enhance shareholder value."

         In evaluating its operating  performance,  the Company  focuses on core
underwriting and investing results before  consideration of realized  investment
gains or  losses  and  amortization  expenses  (these  measures  do not  replace
operating  income or net income computed in accordance  with generally  accepted
accounting  principles  as a measure of  profitability).  The  Company  acquired
Gryphon on  January  15,  1999,  and the  Company's  results  reflect  Gryphon's
operating  results  since that date.  Following is a comparison of 1999 and 1998
results on a per diluted share basis.

         Fourth quarter income from core operations increased 8 percent to $2.29
per  diluted  share from $2.12 per  diluted  share in 1998.  For the year,  core
operating income was $8.17 per diluted share compared to $8.10 per diluted share
a year ago. The growth in both periods resulted from underwriting profits in the
Company's core  underwriting  units partially  offset by Gryphon's  losses.  The
Company has completed the transfer of Gryphon's continuing programs to its three
excess and surplus lines  underwriting  units,  and a dedicated  runoff unit has
been established to aggressively manage Gryphon's discontinued programs.

         Fourth  quarter  1999 gross  premium  volume  rose 41 percent to $143.8
million  from $101.7  million  last year.  For the year,  gross  premium  volume
increased 36 percent to $594.9  million from $437.5  million in 1998.  Excluding
Gryphon,  gross  premium  volume  increased  26 percent  and 12 percent  for the
quarter and year ended  December 31, 1999,  respectively.  The increase in gross
premium volume,  excluding Gryphon, was due to increased submission activity and
stable pricing.

         Fourth  quarter  1999 earned  premium  volume rose 29 percent to $110.1
million from $85.2 million last year. For the year, earned premiums increased 31
percent  to $437.2  million  in 1999 from  $333.3  million  last  year.  Gryphon
contributed earned premiums,  including earned premiums from discontinued lines,
of $10.3 million and $67.3  million for the quarter and year ended  December 31,
1999, respectively.

         Underwriting  performance  is measured by the combined  ratio of losses
and expenses to earned  premiums.  The Company  reported a combined ratio of 101
percent in 1999  compared  to a combined  ratio of 98 percent in 1998.  The 1999
underwriting loss was the result of the Gryphon acquisition.  Excluding Gryphon,
the  Company's  combined  ratio was 96  percent  in 1999.  The  Company  remains
committed  to  underwriting  profits  as the  key  component  of  its  financial
strategy.

         Net  investment  income  rose 23  percent to $87.7  million  from $71.0
million  in  1998.  The  increase  was  primarily  the  result  of  the  Gryphon
acquisition.  The Company  recognized  $0.9 million of net realized  losses from
investment  sales in 1999  compared to $20.6  million of net  realized  gains in
1998. As part of its tax planning strategy, the Company made the decision in the
fourth quarter of 1999 to sell fixed income  securities with  unrealized  losses
and realize the  associated  tax  savings.  Primarily  as a result,  the Company
recognized $10.2 million of net realized investment losses in the fourth quarter
of 1999.  Proceeds were  reinvested  in high quality fixed income  securities at
higher yields.  Variability in the timing of realized and unrealized  investment
gains and losses is to be expected.

         Book value per common share was $68.59 at December  31, 1999,  compared
to $77.02 at December 31, 1998. All of the Company's  investments are considered
available-for-sale  and are  recorded  at  estimated  fair  value.  The  Company
reported net unrealized  gains,  net of taxes,  on its fixed maturity and equity
investments  of $15.4 million at December 31, 1999,  compared to net  unrealized
gains,  net of taxes,  of $96.0 million at December 31, 1998. The fixed maturity
portfolio's  market value declined $43.7 million,  net of taxes,  primarily as a
result of higher interest rates.  The equity  portfolio's  market value declined
$36.9 million,  net of taxes,  primarily as a result of a  concentration  in the
financial services sector. The Company's  disciplined,  value-oriented  approach
has  generated  solid  results  over a long  period of time.  Over the past five
years, the Company has grown book value at a compound annual rate of 22 percent.

         On January  26,  2000,  the  Company  announced  revised  terms for its
acquisition of Terra Nova (Bermuda) Holdings Ltd. (NYSE: TNA). The new agreement
was reached after preliminary  information indicated that Terra Nova will report
a loss for the  fourth  quarter  and for the full year of 1999 and after  taking
into account the decline in the market  price of Markel  shares since the merger
agreement  was signed in August 1999.  Under the revised  agreement,  Terra Nova
shareholders will receive for each ordinary share,  $13.00 in cash, 0.07027 of a
Markel common share and 0.07027 of a Markel  contingent  value right (CVR).  The
CVR is intended to increase the likelihood that a Terra Nova shareholder will be
able to realize a minimum value of $185 for each Markel share received.


         Pursuant  to  the   revised   terms  of  the  merger   agreement,   the
consideration  will consist of approximately  $325 million in cash, 1.76 million
Markel common shares and 1.76 million Markel CVR's. In addition, $175 million of
Terra Nova debt will remain  outstanding.  The acquisition will be accounted for
as a  purchase  transaction.  The  transaction  is subject  to  approval  by the
shareholders of both Markel and Terra Nova, the receipt of necessary  regulatory
approvals and other customary closing conditions.

         The Company has arranged for a five year $500 million  revolving credit
facility which is expected to replace its existing $250 million revolving credit
facility upon closing of the Terra Nova acquisition. Due to the revised terms of
the Terra Nova merger agreement,  the Company is seeking  amendments to the $500
million revolving credit facility. Alternatively, the Company has the ability to
finance the  transaction  through the use of its  existing  credit  facility and
internal funding.

         Markel Corporation markets and underwrites specialty insurance products
and  programs  to a variety  of niche  markets.  In each of these  markets,  the
Company seeks to provide quality products and excellent customer service so that
it can be a  market  leader.  The  financial  goals of the  Company  are to earn
consistent  underwriting  profits  and  superior  investment  returns  to  build
shareholder value.

         This  is  a  "Safe  Harbor"  statement  under  the  Private  Securities
Litigation  Reform  Act  of  1995.  Certain  statements   contained  herein  are
forward-looking  statements that involve risks and uncertainties.  Future actual
results may  materially  differ from those in these  statements  because of many
factors.  The completion of the Terra Nova transaction is subject to the absence
of material adverse changes in the buyer's or seller's  financial  condition and
receipt  of  all  necessary  regulatory  and  shareholder  approvals.  Insurance
industry  price  competition  has made it more  difficult  to attract and retain
adequately  priced  business.  Changing  legal and social  trends  and  inherent
uncertainties  in the loss estimation  process can adversely impact the adequacy
of loss reserves.  The Company's  potential  underwriting  exposure to Year 2000
claims are difficult to predict with any certainty. State regulatory actions can
impede the Company's  ability to charge adequate rates and efficiently  allocate
capital. The frequency and severity of natural catastrophes are highly variable.
Economic conditions and interest rate volatility can have significant impacts on
the market value of fixed  maturity  and equity  investments.  Accordingly,  the
Company's premium growth, underwriting and investment results have been and will
continue to be potentially materially affected by these factors.
