     Accounting Standards No. 115 ("Accounting for Certain Investments in Debt
     and Equity Securities") and (b) any Exempt Indebtedness (and the assets

     United States of America, or by any jurisdiction under the laws of which
     such recipient is organized or resident, in which such recipient has an

     Parties with respect to such Tax under Sections 2.19(a) or 2.19(c) and (d)
     any Tax that is attributable to such Lender's failure or inability (other

     (a) at the time of the incurrence of such Indebtedness by such Person, the
     cash flows from the assets of such Person shall reasonably be expected by
     such Person to liquidate such Indebtedness and all other liabilities
     (contingent or otherwise) of such Person and (b) no portion of such
     Indebtedness of such Person shall be Guaranteed (other than guarantees of
     the type referred to in clause (a) or (b) of the definition of
     Indebtedness) by, or shall be secured by a Lien on any assets owned by, XL
     Capital or any of its Subsidiaries and neither such Person nor any of the
     holders of such Indebtedness shall have any direct or indirect recourse to
     XL Capital or

     limitation of the rights and remedies of the holder of such Lien or the
     lessor under such capital lease to repossession or sale of such property);
     (v) the maximum available amount of all standby letters of credit issued
     for the account of such Person and, without duplication, all drafts drawn

     including any renewals, extensions, restatements or replacements thereof).

          "RC Sublimit" means $1,000,000,000, as such amount may be reduced from

     GAAP (it being understood for avoidance of doubt that any liability or
     obligation excluded from the definition of Indebtedness shall not
     constitute Indebtedness for purposes of this definition).

     (a) Section 2.19(e) of the Credit Agreement is hereby amended and restated
in its entirety as follows:

          "(e) Exemptions. Each Lender and the Administrative Agent shall, at
     the written request of XL Capital, provide to any Account Party such form,
     certification or similar documentation, if any (each duly completed,
     accurate and signed) as is currently required by any Account Party
     Jurisdiction or any other jurisdiction, or comply with such other
     requirements, if any, as is currently applicable in such Account Party
     Jurisdiction or any other jurisdiction, in order to obtain an exemption
     from, or reduced rate of, deduction, payment or withholding of Indemnified
     Taxes or Other Taxes to which such Lender or the Administrative Agent is
     entitled pursuant to an applicable tax treaty or the law of such Account
     Party Jurisdiction or any other jurisdiction; provided that XL Capital
     shall have furnished to such Lender or the Administrative Agent in a
     reasonably timely manner copies of such documentation and notice of such
     requirements together with applicable instructions. Upon the reasonable
     request of XL Capital in writing, each Lender and the Administrative Agent
     will provide to XL Capital such form, certification or similar
     documentation (each duly completed, accurate and signed) as may in the
     future be required by any Account Party Jurisdiction or any other
     jurisdiction, or comply with such other requirements, if any, as may be
     applicable in such Account Party Jurisdiction or any other jurisdiction in
     order to obtain an exemption from, or reduced rate of, deduction, payment
     or withholding of Indemnified Taxes or Other Taxes to which such Lender or
     the Administrative Agent is entitled pursuant to an applicable tax treaty
     or the law of the relevant jurisdiction. In addition, each Lender agrees
     from time to time when a lapse in time or change in circumstances renders
     the previous documentation obsolete or inaccurate in any material respect,
     it will deliver to the Account Parties such properly completed and executed
     documentation as will permit such payments to continue to be made without
     withholding or at a reduced rate, or notify the Account Parties that it is
     unable to do so."

     (b) Section 2.19(f) of the Credit Agreement is hereby amended and restated
in its entirety as follows:

          "(f) If the Administrative Agent or a Lender determines, in its
     reasonable discretion, that it has received a refund from the relevant
     Governmental Authority (in cash or as an offset against another tax
     liability owing to such Governmental Authority) of any Taxes or Other Taxes
     as to which it has been indemnified by an Account Party or with respect to
     which an Account Party has paid additional amounts pursuant to this
     Section, it shall pay over such refund to such Account Party (but only to
     the extent of indemnity payments made, or additional amounts paid, by such
     Account Party under this Section with respect to the Taxes or Other Taxes
     giving rise to such refund), net of all out-of-pocket expenses of the
     Administrative Agent or such Lender and without interest (other than any
     interest paid by the relevant Governmental Authority with respect to such
     refund); provided that such Account Party, upon the request of the
     Administrative Agent or such Lender, agrees to repay the amount paid over
     to such Account Party (plus any penalties, interest or other charges
     imposed by the relevant Governmental Authority) to the Administrative Agent
     or such Lender in the event the Administrative Agent or such


                 Amendment No. 1 to Three-Year Credit Agreement


                                      -5-


     Lender is required to repay such refund to such Governmental Authority.
     This Section shall not be construed to require the Administrative Agent or
     any Lender to make available its tax returns (or any other information
     relating to its taxes not expressly required to be made available hereunder
     which it reasonably deems confidential) to any Account Party or any other
     Person."

     income on such assets received incurred as part of its business including
     activities utilizing ISDA documentation or any Specified Transaction
     Agreement relating and identified to specific insurance payment liabilities
     or to liabilities arising in the ordinary course of any Account Parties' or
     any of their Subsidiary's business as an insurance or reinsurance company
     (including GICs and Stable Value Instruments) or corporate member of The
     Council of Lloyd's or as a provider of financial or investment services or
     contracts, or the proceeds thereof (including GICs and Stable Value
     Instruments), in each case held in a segregated trust, trust or other
     account and securing such liabilities, (ii) assets securing Exempt
     Indebtedness of any Person (other than XL Capital or any of its Affiliates)
     in the event such Exempt Indebtedness is consolidated on the consolidated
     balance sheet of XL Capital and its consolidated Subsidiaries in accordance
     with GAAP or (iii) any other assets subject to any trust or other account
     arising out of or as a result of contractual, regulatory or any other
     requirements; provided that in no case shall any such Lien secure
     Indebtedness and any Lien which secures Indebtedness shall not be permitted
     under this clause (h);".

     2.06. Section 7.06 of the Credit Agreement is hereby amended and restated
in its entirety as follows:

          "Consolidated Net Worth. XL Capital will not permit its Consolidated
