During the first six months of 2001, the Company repurchased 0.2 million of its
shares at an average price of $69.72 per share. XL has approximately $236.3
million remaining in its current share repurchase authorization.

Commenting on the second quarter results, Brian M. O'Hara, President and Chief
Executive Officer of XL, stated "Our results for the second quarter were
satisfactory given the loss activity experienced during the quarter by most
companies and were generally in line with expectations. Overall market
conditions continue to improve as evidenced by the very strong growth in
premiums written during both the second quarter and for the first six months of
2001."

"We were also very pleased to announce the completion of our acquisition of
Winterthur International in late July. This acquisition gives XIL the platform
it needs for significant international expansion," Mr. O'Hara noted.

The all-cash transaction, announced by XL on February 16, 2001, is valued at
approximately $405 million. This value is based on financial statements for the
Winterthur International ("WI") business being acquired as at and for the period
ending December 31, 2000 delivered to XL (the "December WI Financial
State-



                                      -3-

ments"), and is subject to adjustment based on the completion of audited
financial statements for WI as at and for the period ending June 30, 2001. These
June 30, 2001 financial statements are subject to review and agreement by XL and
its auditors.

The acquisition of WI will be given effect in XL's financial statements from and
after July 1. Based upon the December WI Financial Statements, WI recorded gross
written premium and net written premium of $1.2 billion and $493 million,
respectively, for the year ended December 31, 2000. In addition, WI had total
assets, total investment assets and total gross reserves of $4.4 billion, $1.0
billion and $2.4 billion, respectively, at December 31, 2000.

Jerry M. de St. Paer, Executive Vice President and Chief Financial Officer of XL
stated, "Under current accounting rules, we expect to record at fair value
Winterthur International's loss reserves based on the present value of their
cash flows. In such estimate, we utilized a blended discount rate based upon the
expected pay out patterns of the reserves, resulting in an aggregate adjustment
of approximately $55 million (pre-tax) to Winterthur International's reserves,
which discount will be charged through the income statement over the period that
claims are settled. In addition, we expect to record a special charge of
approximately $80 million in our third quarter with respect to the acquisition,
of which $61 million relates to our estimate of that portion of adverse loss
development for which XL does not have indemnification from the seller."

"Including the reserve discount charges, we expect the acquisition to be
slightly dilutive to our GAAP operating income per share for fiscal 2001,"
commented Mr. de St. Paer. "We expect the acquisition to be modestly accretive
to both operating income and net income per share for fiscal 2002."

XL expects to file the December WI Financial Statements and pro forma financial
information giving effect to the WI acquisition with the SEC on a Form 8-K later
this week. This filing will contain a description of the assumptions and bases
upon which these financial statements and pro forma information were based. The
December WI Financial Statements were delivered to XL by Winterthur Swiss
Insurance pursuant to the sale and purchase agreement and have not been
independently reviewed by XL or its auditors. The December WI Financial
Statements and the pro forma financial information are not the basis upon which
the final purchase price for WI will be determined and are not indicative of
future performance of the WI operations. The December WI Financial Statements
and pro forma financial information should be reviewed with caution and undue
reliance should not be placed upon them or any of the financial or other
information contained in them.

2.   The underwriting expense ratio excludes exchange gains and losses.
3.   The combined ratio for the financial services segment would have been 65.4%
     if fee income was included with net premiums earned for purposes of
     calculating the expense ratio.
4.   The Company's Lloyd's syndicates are included in the insurance segment but
     are disclosed separately since the nature of the business written and the
     market in which the syndicates underwrite are significantly different from
     the Company's other insurance subsidiaries.

5.   Net losses incurred for the insurance segment include, and the reinsurance
     segment exclude, $11.2 million relating to an intercompany stop loss
     agreement. Consolidated results are not affected. The loss and loss expense
     ratio would have been 53.4% and 73.1% and the $(19.6) million in the
     insurance and reinsurance segments, respectively, had this stop loss
     agreement not been in place.

NOTES:
1.   Ratios are based upon net premiums earned, excluding fee income and other.
2.   The underwriting expense ratio excludes exchange gains and losses.
3.   The combined ratio for the financial services segment would have been 94.4%
     if credit default swap fee income was included with net premiums earned for
     purposes of calculating the expense ratio.
4.   The Company's Lloyd's syndicates are included in the insurance segment but
     are disclosed separately since the nature of the business written and the
     market in which the syndicates underwrite are significantly different from
     the Company's other insurance subsidiaries.

[?] reinsurance segment exclude, $11.2 million relating to an intercompany stop
loss agreement. Consolidated results are not affected. The loss and loss expense
ratio would have been 55.9% and 65.0% and the underwriting profit would have
been $55.1 million and $0.2 million in the insurance and reinsurance segments,
respectively, had this stop loss agreement not been in place.
