            W. R. BERKLEY CORPORATION ANNOUNCES THIRD QUARTER RESULTS

     Greenwich, CT, October 25, 2001 -- W. R. Berkley Corporation (NYSE: BER)
today reported that operating income, excluding losses related to the September
11th event, was $11 million, or 36 cents per diluted share, for the third
quarter ended September 30, 2001 compared with $9 million, or 34 cents per
diluted share, for the same period in 2000. For the first nine months, operating
income, excluding losses related to the September 11th event, was $38 million,
or $1.35 per diluted share, in 2001, compared with operating income of $25
million, or 96 cents per diluted share, in 2000. Operating income represents net
income excluding discontinued businesses, realized investment gains and
restructuring charges.

     After-tax losses related to the September 11th event were $23 million, or
78 cents per diluted share. Pretax losses from the September 11th event are
estimated to be $35 million, net of reinsurance recoveries. This represents the
company's maximum retention for property and business interruption coverages and
its estimated policy limits on risks exposed to casualty losses.

     The company also announced plans to discontinue two lines of business that
are not likely to achieve a satisfactory return on capital. The company is
withdrawing from the personal lines business, both homeowners and private
passenger automobile. The company will stop writing new personal

lines policies immediately and will not renew existing policies, subject to all
regulatory requirements. In addition, the company is discontinuing the
alternative market division of its reinsurance business. The after-tax loss
related to the discontinued businesses was $40 million, or $1.37 per diluted
share, in the third quarter of 2001.

     The net loss for the third quarter of 2001 was $47 million, or $1.63 per
diluted share, compared with net income of $7 million, or 27 cents per diluted
share, for the third quarter of 2000. The company reported a net loss of $27
million, or 97 cents per diluted share, for the first nine months of 2001,
compared with net income of $18 million, or 70 cents per diluted share, in the
first nine months of 2000.

     Net premiums written for on-going business increased 31 percent to $418
million for the third quarter of 2001 from $319 million for the year-earlier
period. The premium growth was led by the company's specialty business, which
reported a 92 percent increase in net premiums written for the quarter. Net
premiums written for on-going business increased 25 percent in the first nine
months of 2001 to $1,187 million.

     Due to lower returns available for the merger arbitrage business as well as
lower returns on investment of new cash flow, net investment income decreased by
$10 million to $47 million in the third quarter of 2001. For the first nine
months net investment income was $148 million in 2001 compared with $153 million
in the year-earlier period.

     Commenting on the company's results, William R. Berkley, chairman and chief
executive officer, said: "We continue to examine each area of our business as we
seek to achieve a 15 percent rate of return on capital. As part of this
strategy, we have decided to eliminate our personal lines business and the
alternative markets division of our reinsurance business. As a result, we expect
our regional and reinsurance segments to be in a better position to achieve our
targeted returns as well as to substantially reduce our weather-related
volatility.

     "These changes should substantially improve our returns in 2002 and beyond.
Our specialty and facultative reinsurance businesses are generating price
increases in excess of 30 percent. Our regional business continues to generate
price increases for commercial lines in the low double digits, and we are
finally seeing significant price increases in the treaty reinsurance
marketplace. Our alternative markets segment continues to deliver exceptional
results, and our international unit is still delivering solid returns, in spite
of local economic conditions. We expect to show an underwriting profit next
year.

     "We expect 2002 to be the first year in many that we approach our targeted
15 percent after tax return while at the same time producing substantial premium
growth. Based on the current marketplace, we would expect 2003 to be
substantially better," Mr. Berkley concluded.
