        NOTES TO THE UNAUDITED PRO FORMA CONDENSED FINANCIAL INFORMATION


                      Expressed in thousands of U.S dollars
                                   (Unaudited)

1.   Basis of presentation

     The unaudited pro forma condensed financial information is based upon the
historical financial statements of XL Capital Ltd ("XL Capital") included in its
annual report on Form 10-K for the year ended December 31, 2000 and the
historical financial statements of Winterthur International as at and for the
year ended December 31, 2000 included under exhibit 99(b) of this Form 8-K.

     The unaudited pro forma condensed income statement has been prepared to
reflect the acquisition of Winterthur International as if the acquisition had
occurred as of January 1, 2000. The unaudited pro forma condensed balance sheet
has been prepared as if the acquisition had occurred as at December 31, 2000.
The combination of XL Capital Ltd and Winterthur International is being
accounted for under purchase accounting rules, in accordance with generally
accepted accounting principles in the United States, whereby the total purchase
price is allocated to the fair values of the assets and liabilities acquired,
and the excess of the total purchase price over the fair values is recorded as
goodwill. The fair values ascribed to the individual assets and liabilities are
based upon management estimates and appraisals. The pro forma adjustments have
been made solely for the purposes of developing such pro forma information. The
final allocation may be different from these estimates and there can be no
assurances that such differences, if any, will not be material. On July 20, 2001
the Financial Accounting Standards Board issued Statements of Financial
Accounting Standards No. 142, Goodwill and Other Intangible Assets ("SFAS No.
142"). Since the transaction closed after June 30, 2001, goodwill amortization
has not been recorded in the pro forma adjustments in accordance with SFAS No.
142.

     The pro forma financial information does not purport to be indicative of
the results of operations that would have occurred had the transaction been
consummated on the assumed dates, nor is the information intended to be a
projection for any future period.

3.   Pro forma Financial Information

The following adjustments have been made to present the financial information
for the combined entities on a pro forma basis :

     (a)  Restatement of Winterthur International real estate held for
          investment to fair value.

     (b)  Restatement of other fixed assets to fair value.

     (c)  Management has estimated the fair value adjustment of approximately
          $52.8 million on net loss reserves and net unearned premium reserves
          of Winterthur International as at December 31, 2000. The gross loss
          reserves and the associated reinsurance recoverable amounts are
          approximately $96.9 million and $44.1 million, respectively.
          Management estimates that approximately 65% or $34.6 million of the
          fair value adjustment will be charged to earnings over the next five
          years.

          The fair value adjustment estimate consists of two components; 1)
          discounting the net loss reserves and unearned premium reserves to
          present value using a risk free rate of return, net of deferred taxes,
          and 2) developing an expense, profit and risk margin for the acquired
          reserves based on managements' estimate of current market pricing and
          the terms in the Sale and Purchase Agreement.

          The expected payment patterns for the gross loss reserves and the
          associated reinsurance recoverable amounts are derived by developing
          separate payment patterns for the gross loss reserves using historical
          Winterthur International data by line of business and for the
          associated reinsurance recoverable amounts by lagging the gross payout
          patterns. In addition, management has estimated a 5% risk and profit
          margin within these reserves. This margin is based on current pricing
          quotes expected from a prospective reinsurer or other third party
          assuming the same risk and takes into account the reserve seasoning
          protection provided by the seller to the Registrant. Determination of
          a fair value for the net unearned premium reserve follows a similar
          approach to that applied to the loss reserves but with some minor
          adjustments.

     (d)  Elimination of deferred tax assets included in book value.

     (e)  Establishment of net deferred tax liability.

     (f)  The recognition of the fair value of goodwill, insurance licenses and
          other intangibles on acquisition, being the excess of the purchase
          price over the fair value of the net tangible assets of Winterthur
          International as shown in note 2. The allocation of this amount
          between goodwill, insurance licenses and other intangible assets will
          be performed by the Registrant shortly after the acquisition date,
          based upon independent appraisals. No estimate is currently available.

     (g)  XL Capital raised $600 million of zero coupon convertible debt in June
          2001 used in part to finance the acquisition of Winterthur
          International. For the purposes of this pro forma information, it has
          been assumed that debt was raised to finance the

                                      -5-


          purchase price in the amount of $405,593 (excluding estimated
          acquisition related costs of $22,500) under the same terms and
          conditions as the issue of the convertible debt and that there was no
          dilution effect on the weighted average number of shares outstanding
          for the year ended December 31, 2000.

     (h)  Recording of the liability for certain legal, audit, consulting and
          other costs in connection with the acquisition.

     (i)  Amortization of the fair value adjustment to the net loss reserves and
          unearned premium reserves for the year ended December 31, 2000 as
          described in note 3(c).

     (j)  Adjustment to depreciation charge for the year ended December 31, 2000
          relating to the fair value adjustment of the fixed assets as described
          in note 3(b).

     (k)  Interest expense on the convertible debt of $405,593 as described in
          note 3(g) above.

     (l)  Current year tax effect of pro forma adjustments to the income
          statement for the year ended December 31, 2000.

4.   The Sale and Purchase Agreement defines certain portfolios of business of
     Winterthur International which are included in this transaction as well as
     certain lines of business which are excluded from this transaction. The net
     reserves and liabilities relating to these portfolios and excluded lines of
     business are included in the relevant balance sheet captions in this pro
     forma financial information, consistent with the audited financial
     statements of Winterthur International as at and for the year ended
     December 31, 2000. Included in investment assets and cash of Winterthur
     International, for the purposes of this pro forma information is a net
     amount of $345,023 representing an amount equivalent to those net reserves
     and liabilities.

5.   Future cost savings and non-recurring exit costs relating to duplicate
     business areas are not anticipated to be significant and have therefore
     been excluded from the pro forma adjustments. The pro forma adjustments
     also do not give effect to any integration of the Winterthur International
     operations with certain operations of the Registrant or for the
     Registrant's share of any adverse or positive reserve development that may
     occur during the seasoning period.
