XL CAPITAL LTD EXPECTS THIRD-QUARTER 2008
BOOK VALUE TO RANGE FROM $21.00 TO $22.50 PER ORDINARY SHARE

HAMILTON, BERMUDA, October 10, 2008 – XL Capital Ltd (“XL” or the “Company”) (NYSE: XL) provided the following preliminary metrics on its expected third quarter 2008 results. The results for the quarter are currently being reviewed by the Company’s independent auditors and accordingly the estimates below are subject to change.

• Book value, as of September 30, 2008, is expected to be in the range of $21.00 to $22.50 per ordinary share on a fully diluted basis. On that date, the Company’s total common share count was approximately 330.8 million.

• The Company estimates that during the third quarter of 2008, the decline in value of its investment portfolio (comprised of changes in unrealized losses, other than temporary impairments and realized losses on securities sales) due to movements in market prices was in a range of $1.0 billion to $1.2 billion.

• XL’s estimated book value per ordinary share as of September 30, 2008 (as estimated above) was also negatively impacted, although to a lesser extent, by the strengthening of the US Dollar versus other leading currencies during the period.

XL also announced that it intends to hold a conference call to discuss this announcement and the quarter’s preliminary results at 8:30 a.m. Eastern Time on Tuesday, October 14, 2008.

I believe that the preliminary estimates we have provided today will assist in these efforts. The next time that we expect to be able to provide further meaningful financial information is early next week and I look forward to doing so on our call on Tuesday.”
