                 W. R. BERKLEY CORPORATION ANNOUNCES RESULTS OF
                 OPERATIONS FOR THE FOURTH QUARTER AND FULL YEAR

     Greenwich, CT, February 5, 2001 -- W.R. Berkley Corporation (NASDAQ: BKLY)
today reported revenues for the fourth quarter ended December 31, 2000 increased
14 percent to $480 million from $422 million for the same period in 1999.

     Revenues for the year increased six percent to $1,781 million from $1,674
million in 1999.

     Operating income for the fourth quarter was $14 million, or 53 cents per
diluted share, compared with an operating loss of $38 million, or $1.50 per
diluted share, for the fourth quarter of 1999. Operating income for the year was
$32 million, or $1.23 per diluted share, compared with an operating loss of $23
million, or 91 cents per diluted share, for 1999. In the 1999 fourth quarter,
the Company established additional loss reserves for the regional insurance
group of approximately $55 million (before tax). There was no comparable reserve
adjustment in 2000.

     Net income for the fourth quarter was $18 million, or 68 cents per diluted
share, compared with a net loss of $41 million, or $1.59 per diluted share, for
the 1999 period. Net income for the year was

$36 million, or $1.39 per diluted share, compared with a net loss of $37
million, or $1.43 per diluted share, for 1999. Net income includes realized
investment gains and losses, restructuring charges, extraordinary items and
changes in accounting principles, which are not part of operating income.

     Commenting on the Company's results, William R. Berkley, chairman and chief
executive officer, said: "We are very pleased with our fourth quarter results
and believe they reflect a clear sign of the improving environment and the
actions we have taken to date. Our annualized return approached double digits in
the fourth quarter, while for the year our reserves increased at a greater rate
than the increase in our premium volume. We continue to implement further
substantial price increases, in addition to those previously put in place.

     "Book value increased by approximately 15 percent for the year. We
anticipate improved returns for 2001 and are enthusiastic about prospects for
2002. We expect that pricing will continue to tighten in commercial lines for
the next several years."

Broadcasting Network Vcall website. Those who want to hear the conference call
