First quarter highlights include:

     o    Net operating return on equity was 18.8% annualized, or 4.7% for the
          quarter

     o    Net premiums written grew 41% to $892 million

     o    Net premiums written for specialty insurance and facultative
          reinsurance grew by 49% and 118%, respectively

     o    GAAP combined ratio improved by 4.3 percentage points to 91.8%

     o    Cash flow from operations increased to $276 million

     o    The paid loss ratio decreased to 39% in the first quarter from 59% in
          the prior year quarter

     Commenting on the Company's performance, William R. Berkley, chairman and
chief executive officer, said: "The results for the first quarter continue the
positive trends we've seen the past twelve months. All units of the property
casualty business generated underwriting profits except for treaty reinsurance,
where we are still seeing loss development from prior years. Our cash flow from
operations was over $275 million for the quarter. Investment income also
increased substantially, reflecting increased cash flow and greater invested
assets. The Company's portfolio duration declined slightly during the period.

     "Our accident year results continue to be exceptional. Prices are still
moving up, although the pace of those increases has moderated somewhat.
Increases this year were over 12% for regional business, more than 25% for
specialty business and in excess of 30% for reinsurance business. We expect
continued improvement in underwriting profitability.

     "Our expectation for ongoing growth and improved profitability has not
changed. We remain confident and enthusiastic about our opportunities for
increased profits and growth for the next several years," Mr. Berkley concluded.

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

(2)  Segment operating results for the prior period 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.
     Restated operating results by segment for each of the five years ended
     December 31, 2002 are presented in a separate table below.

(1)  Catastrophe losses were $7 million pre-tax, or 8 cents per share after-tax, in the
     first quarter of each of 2003 and 2002.

(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 $97 million and $105 million as of March 31, 2003 and December 31, 2002,
     respectively.

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

(2)  Segment operating results 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.
