Second quarter highlights include:

o    Net operating return on equity was 20.2% annualized, or 5.1% for the
     quarter

o    Net premiums written were $875.5 million, an increase of 46% from the
     second quarter of 2002

o    GAAP combined ratio improved by 5.0 percentage points to 91.6% from 96.6%
     in the prior year period

o    Cash flow from operations increased 121% to $320.6 million compared with
     $145.3 million in the year-earlier period

o    The paid loss ratio decreased to 37.0% from 56.5% in the prior year quarter

o    Realized investment gains were $43.7 million compared with realized losses
     of $8.4 million in the second quarter of 2002


     Commenting on the Company's performance, William R. Berkley, chairman and
chief executive officer, said: "We are very pleased with our second quarter
results. The net operating return on equity exceeded 20% on an annualized basis.
Net premiums written grew 46% over last year's second quarter due to price
increases, which averaged over 25% on renewed business, and to growth in policy
counts.

     "We continue to have the ability to raise prices. Given the low inflation
environment, even modest price increases can significantly increase our return
on equity. We do not foresee a return to the intense price competition of the
late 1990's any time soon, given the current low interest rate environment and
the challenges faced by many companies in the industry.

     "We have continued to shorten the duration of our investment portfolio and
have accumulated more than a billion dollars of cash. As a consequence of this
strategy, our investment income has been adversely impacted in the short run. We
believe that our willingness to forgo the slightly higher yields available by
extending the duration of our portfolio will be rewarded by better investment
opportunities in the future.

     "We have strengthened our capital position and are taking advantage of
opportunities to expand our business with a continued focus on casualty lines.
We remain confident in our prospects and expect that quarterly results will
continue to improve," Mr. Berkley concluded.

(1)  Underwriting ratios represent losses, loss expenses and underwriting
     expenses expressed as a percentage of premiums earned. Underwriting
     expenses do not include expenses related to insurance services or
     unallocated corporate expenses.

(2)  Segment operating results for the prior periods have been restated to
     reflect two changes in the accounting presentation. First, operating
     results for Vela Insurance Services, Inc., an excess and surplus lines
     underwriting manager, were transferred from the reinsurance segment to the
     specialty segment as a result of a change in management responsibility for
     this business. Second, in the fourth quarter of 2002, the Company modified
     the presentation of reinsurance assumed from Lloyd's syndicates to reflect
     the Company's share of the reinsurance and brokerage costs paid by the
     syndicates. Previously, these amounts were netted against assumed premiums.

(1) For the second quarter of 2003 catastrophe losses were $21 million
    pre-tax, or 24 cents per share after-tax, compared with $21
    million pre-tax, or 26 cents per share after-tax, in the year
    earlier period.  For the first six months of 2003, catastrophe
    losses were $28 million pre-tax, or 32 cents per share
    after-tax, compared with $27 million pre-tax, or 35 cents per
    share after-tax, in the year earlier period.

(2) Net operating income is a non-GAAP financial measure defined by the
    Company as net income excluding gains and losses on
    investments, foreign currencies and discontinued business.
    Management believes that excluding investment and foreign
    currency gains, which result primarily from changes in general
    economic conditions, and excluding results of businesses that
    have been discontinued provides a useful indicator of trends in
    the Company's underlying and on-going operations. Net operating
    return on equity represents net operating income expressed as a
    percentage of beginning of year stockholders' equity, adjusted
    for stock transactions.

(3) Investments include trading account receivable from brokers and
    clearing organizations and trading securities sold but not yet
    purchased.

(4) Stockholders' equity includes after-tax unrealized gains from
    investments and foreign exchange of $132 million and $105
    million as of June 30, 2003 and December 31, 2002,
    respectively.
