                   W. R. BERKLEY CORPORATION ISSUES STATEMENT

                          ON WORLD TRADE CENTER TRAGEDY


                   Company Estimates Potential Pre-Tax Losses


     GREENWICH, CT., September 14, 2001 - W. R. Berkley Corporation (NYSE: BER)
Chairman William R. Berkley issued the following statement today, "The events of
the past several days have created much sadness in America as well as a sense of
deep personal concern within our organization. This has not altered our
confidence in our institutions or the importance of individual freedom. We have
many friends who lost their lives in this abominable terrorist act and to all
the families that suffered we offer our condolences."

     In addressing the business issue, Mr. Berkley commented, "Although it is
too early to make a precise assessment of the financial impact to the company of
these events, based on our preliminary analysis and our examination of all known
exposures, we do not expect our pre-tax losses to exceed $10 million. In the
unlikely event all reinsurance retentions are exhausted, our company's net
pre-tax losses would be less than $25 million. We do not currently believe that
we have any significant liability exposures."

     Founded in 1967, W. R. Berkley Corporation is an insurance holding company,
which operates in five segments of the property casualty insurance business:
specialty insurance, alternative markets, reinsurance, regional property
casualty insurance and international.
