           W. R. BERKLEY CORPORATION ANNOUNCES SECOND QUARTER RESULTS

     Greenwich, CT, July 26, 2001 -- W. R. Berkley Corporation (NYSE: BER) today
reported net premiums written increased 30 percent to $454 million for the
second quarter ended June 30, 2001 from $350 million in the year-earlier period.
The premium growth was led by the company's specialty business, which reported
an 81 percent increase in net premiums written for the quarter. For the first
six months of 2001, total net premiums written for the company increased 20
percent to $886 million.

     Operating income was $8 million, or 26 cents per diluted share, for the
second quarter of 2001 compared with $6 million, or 25 cents per diluted share,
for the same period in 2000. For the first six months, the company reported
operating income of $17 million, or 58 cents per diluted share, in 2001 compared
with $12 million, or 45 cents per diluted share, in 2000.

     Net income for the second quarter of 2001 was $10 million, or 32 cents per
diluted share, compared with $7 million, or 26 cents per diluted share, for the
second quarter of 2000. For the first six months of 2001, net income was $20
million, or 68 cents per diluted share, compared with $11 million, or 43 cents
per diluted share, in 2000.

     Commenting on the company's results, William R. Berkley, chairman and chief
executive officer, said: "It has been an exciting quarter. While our results
were severely impacted by storm activity, more than half of which related to our
personal lines business, the overall direction of our key operating divisions
continues to show excellent progress.

     "Gross premiums written for specialty, alternative markets and facultative
reinsurance grew by approximately 50 percent over the second quarter last year.
These gains in premium volume primarily reflect price increases, although there
was slight growth in policy count. Our pre-tax operating income in the second
quarter increased by more than 80 percent over the comparable quarter a year
ago."

     Mr. Berkley continued, "We made several changes which will generate a
marked increase in our premium volume over the next five quarters, including
purchasing less reinsurance. This is not likely, however, to have a
consequential impact on our overall profitability during the balance of the
year, but should substantially increase our investable assets in the long term
and create additional future investment income. In addition, we continue to
raise prices in all areas of the business and anticipate price improvements to
continue in the foreseeable future.

     "We expect improvement in operating results and substantial growth in our
gross and net premiums. We are continuing to focus our efforts on the specialty
and alternative markets segments, which offer extraordinary opportunities in the
current marketplace. We also are benefiting from the improving operating results
at our regional businesses. Our international business is delivering
double-digit returns, and we are generating outstanding results from our
facultative reinsurance business. The current underwriting year results for the
balance

of our reinsurance business are slowly showing signs of improvement, although we
continue to be adversely impacted by the underpriced business written in prior
years.

     "The direction of our company continues to be extremely positive, and we
remain optimistic," Mr. Berkley concluded.

(1)  Pre-tax operating income represents segment earnings before realized investment gains,
     restructuring charges and minority interest.
(2)  In 2001, the company realigned the operating segments to reflect changes in the
     organizational structure of the business. Segment information for the prior period has been
     restated to reflect the change.
(3)  The decrease in reinsurance operating income for the second quarter reflects unfavorable
     prior year loss development. The increase in the expense ratio and decrease in the loss
     ratio reflects the effects of a new group-wide reinsurance treaty.
