*Operating income (loss) represents net earnings (loss) per share on a GAAP
(generally accepted accounting principles) basis less the net gain or loss on
investment transactions taxed at the federal income tax rate.

      AIHL recorded pre-tax earnings of $75.2 million on revenues of $217.0
million in the 2004 second quarter, compared with pre-tax earnings of $2.7
million on revenues of $38.3 million in the second quarter of 2003, and pre-tax
earnings of $165.9 million on revenues of $448.3 million in the first six months
of 2004, compared with pre-tax earnings of $7.6 million on revenues of $77.0
million in the first six months of 2003. AIHL's 2004 second quarter net earnings
include after-tax investment income of $6.5 million and a realized after-tax net
gain on investment transactions of $2.8 million, compared with after-tax
investment income of $3.3 million and no realized after-tax net gain on
investment transactions in the corresponding 2003 period. AIHL's 2004 second
quarter after-tax investment income reflects a larger invested asset base,
principally due to capital contributions by Alleghany and the acquisition of
RSUI in July 2003.

      The comparative pre-tax contributions to AIHL's results made by its
operating units RSUI, CATA and Darwin were as follows (in thousands, except
ratios):

(1)   Since July 1, 2003.

(2)   Includes the results of Platte River Insurance Company, which was acquired
      contemporaneously with CATA in January 2002 and operates in conjunction
      with CATA.

(3)   Although Darwin is an underwriting manager for Platte River and certain
      subsidiaries of CATA, the results of business generated by Darwin have
      been separated from CATA's results for purposes of this table. Since
      Darwin commenced operations in May 2003, it generated minimal business
      during the second quarter and first six months of 2003. Therefore, ratios
      for such periods are not separately presented.

(4)   Represents net premiums earned less loss and loss adjustment expenses and
      underwriting expenses, all as determined in accordance with generally
      accepted accounting principles in the United States of America ("GAAP"),
      and does not include income derived from



      investments. Underwriting profit (loss) does not replace net income (loss)
      determined in accordance with GAAP as a measure of profitability; rather,
      it provides a basis for management to evaluate the underwriting
      performance of its insurance operating units.

(5)   Loss and loss adjustment expenses divided by net premiums earned, all as
      determined in accordance with GAAP.

(6)   Underwriting expenses divided by net premiums earned, all as determined in
      accordance with GAAP.

(7)   The sum of the Loss Ratio and Expense Ratio, all as determined in
      accordance with GAAP, representing the percentage of each premium dollar
      an insurance company has to spend on losses (including loss adjustment
      expenses) and underwriting expenses.

      RSUI's favorable underwriting results in the first six months of 2004,
particularly with respect to its commercial property line, reflect the absence
of any significant catastrophe losses and lower than expected commercial
property non-catastrophe losses during the 2004 second quarter. RSUI's
commercial property business is exposed to catastrophe losses which have
historically occurred more frequently during the second and third quarters.

      The increase in CATA's gross premiums written in the second quarter and
first six months of 2004 compared with the corresponding 2003 periods primarily
reflects premiums generated from an expansion of its business into the excess
and surplus markets. CATA's 2004 second quarter underwriting results reflect
better underwriting margins on the current accident year, offset by a resulting
increase in profit commissions and a $2.9 million pre-tax charge related to loss
reserve development on contract surety and commercial multi-peril liability
business written by CATA in the 2003 and prior accident years.

      Darwin's results in the second quarter and first six months of 2004
continue to reflect start-up expenses incurred to support expected future
premium levels, as well as increased competition across all of its lines of
business.

      World Minerals recorded pre-tax earnings of $5.6 million on revenues of
$71.3 million in the second quarter of 2004, compared with pre-tax earnings of
$6.5 million on revenues of $69.0 million in the corresponding period in 2003,
and pre-tax earnings of $10.8 million on revenues of $138.3 million in the first
six months of 2004, compared with pre-tax earnings of $11.4 million on revenues
of $131.1 million in the first six months of 2003. The 2004 first half results
reflect lower margins due to competitive pricing pressures and increased energy,
labor and benefit costs, partially offset by the continuing favorable impact of
the strong euro versus the U.S. dollar and an increase in net shipments.

      Corporate activities recorded a pre-tax loss of $6.4 million on revenues
of $45.8 million in the second quarter of 2004, compared with a pre-tax loss of
$0.5 million on revenues of $37.1 million in the corresponding period in 2003,
and a pre-tax loss of $6.5 million on revenues of $91.5 million in the first six
months of 2004, compared with pre-tax earnings of $1.3 million on revenues of
$74.9 million in the corresponding 2003 period. Corporate activities includes
parent company results and the results of miscellaneous subsidiaries, including
Heads & Threads International LLC and Alleghany Properties, Inc. The 2004
results for corporate activities reflect increased expense for stock-based
incentive compensation due to a significant increase in the market price of
Alleghany common stock from June 30, 2003 to June 30, 2004.

      As of June 30, 2004 Alleghany beneficially owned approximately 8.0 million
shares, or 2.1 percent, of the outstanding common stock of Burlington Northern
Santa Fe Corporation, which had an aggregate market value on that date of
approximately $280.6 million, or $35.07 per



share, compared with a market value on June 30, 2003 of $227.5 million, or
$28.44 per share. The aggregate cost of such shares is approximately $96.6
million, or $12.07 per share.

      Alleghany has previously announced that it may purchase shares of its
common stock in open market transactions from time to time. In the second
quarter of 2004, Alleghany did not purchase any shares of its common stock. As
of June 30, 2004, Alleghany had 7,675,313 shares of common stock outstanding
(which includes the stock dividend declared in March 2004).

      Additional information regarding the 2004 second quarter results of
Alleghany and its operating units is contained in Alleghany's Report on Form
10-Q for the quarter ended June 30, 2004, which was filed with the U.S.
Securities and Exchange Commission on August 3, 2004.
