      business and operations (including those affected by material suppliers,
      vendors and customers) that could be adversely affected by the risk that

      customers that may give rise to claims under insurance policies issued by
      XL Capital or any Subsidiary of XL Capital) may be unable to recognize and

      developed a plan and timetable for addressing the Year 2000 Problem on a
      timely basis. Based on the foregoing, XL Capital believes that all
      computer applications of XL Capital and its Subsidiaries that are material
      to its or any of its Subsidiaries' business and operations are reasonably
      expected on a timely basis to be able to perform properly date-sensitive
      functions for all dates before and after January 1, 2000 ("Year 2000
      Compliant"), except to the extent that a failure to do so could not
      reasonably be expected to have a Material Adverse Effect."

            2.16. Section 11.06 of the Credit Agreement is hereby amended by
adding thereto a new paragraph (j) as follows:

            "(j) Designated Lenders. Notwithstanding anything to the contrary
      contained herein, any Bank (a "Designating Lender") may grant to an
      Eligible Designee identified as such (and as a Designated Lender) in
      writing from time to time by such Designating Lender to the Administrative
      Agent and the Borrowers, the option to provide to the Borrowers all or any
      part of any Loan that such Designating Lender would otherwise be obligated
      to make to any Borrower pursuant to this Agreement; provided that nothing
      herein shall constitute a commitment by such Designated Lender to make any
      Loan, (ii) if a Designated Lender elects not to exercise such option or
      otherwise fails to provide all or any part of such Loan, the Designating
      Lender shall be obligated to make such Loan pursuant to the terms hereof.
      The making of a Loan by a Designated Lender hereunder shall utilize the
      Commitment of the Designating Lender to the same extent, and as if, such
      Loan were made by such Designating Lender. Each party hereto hereby agrees
      that no Designated Lender shall be liable for any indemnity or similar
      payment obligation under this Agreement (all liability for which shall
      remain with the Designating Lender). In furtherance of the foregoing, each
      party hereto hereby agrees (which agreement shall

      one year and one day after the payment in full of all outstanding
      commercial paper or other senior indebtedness of any Designated Lender, it
      will not institute against, or join any other Person in instituting
      against, such Designated Lender any bankruptcy, reorganization,
      arrangement, insolvency or liquidation proceedings under the laws of the
      United States or any State thereof. As to any Loans or portion thereof
      made by it, each Designated Lender shall have all the rights that a Bank
      making such Loans or portion thereof would have had under this Agreement
      and otherwise; provided that (i) its voting rights under this Agreement
      shall be exercised solely by its Designating Lender, (ii) its Designating
      Lender shall be deemed to hold its relevant Note as agent for such
      Designated Lender to the extent of the Loans or portion thereof funded by
      such Designated Lender and (iii) the designation of a Designated Lender
      and the funding of Loans by a Designated Lender shall in no event (x)
      subject any of the Borrowers to any delay in the making of a Loan, (y)
      cause or give rise to any obligation of any of the Borrowers to indemnify
      or hold harmless such Designated Lender or any other Person (including
      without limitation pursuant to Sections 5.05 and 11.03 hereof) except to
      the extent such obligation would have arisen in favor of the Designating
      Lender or another Person if the Designating Lender (rather than such
      Designated Lender) had made all of such Designated Lender's Loans and such
      Designated Lender had not been designated as such hereunder, or (z) render
      the performance of any provisions of the Agreement illegal, void or
      unenforceable under any provision of law. Each Designating Lender shall
      act as administrative agent for its Designated Lender and give and receive
      notices and other communications on behalf of its Designated Lender. Any
      payments for the account of any Designated Lender shall be paid to its
      Designating Lender as administrative agent for such Designated Lender and
      neither the Borrowers nor the Administrative Agent shall be responsible
      for any Designating Lender's application of such payments. In addition,
      any Designated Lender may (i) with notice to, but without the prior
      written consent of, XL Capital and the Administrative Agent and without
      paying any processing fee therefor, assign all or a portion of its
      interests in any Loans to the Designating Lender or to any financial
      institutions (consented to by XL Capital and the Administrative Agent)
      providing liquidity and/or credit support to or for the account of such
      Designated Lender to support the funding or maintenance of Loans and (ii)
      disclose on a confidential basis any non-public information relating to
      its Loans or portions thereof to any rating agency, commercial paper
      dealer or provider of any surety, guarantee or credit or liquidity
      enhancement to such Designated Lender. This Section 11.06(j) may not be
      amended without the written consent of each Designating Lender which has
      designated a Designated Lender."

            2.17. The Credit Agreement is hereby amended by adding a new Section
12 to read as follows:

                  Amendment No. 2 to Credit Agreement (5-Year)



                                      -12-


            "Section 12. Guarantee.

            12.01. The Guarantee. Each Guarantor hereby jointly and severally
      guarantees to each Bank and the Administrative Agent and their respective
      successors and assigns the prompt payment in full when due (whether at
      stated maturity, by acceleration or otherwise) of the principal of and
      interest on the Loans made by the Banks to each of the Borrowers (other
      than such Guarantor in its capacity as a Borrower hereunder) and all other
      amounts from time to time owing to the Banks or the Administrative Agent
      by such Borrowers under this Agreement, in each case strictly in
      accordance with the terms thereof (such obligations being herein
      collectively called the "Guaranteed Obligations"). Each Guarantor hereby
      further jointly and severally agrees that if any such Borrower shall fail
      to pay in full when due (whether at stated maturity, by acceleration or
      otherwise) any of the Guaranteed Obligations, such Guarantor will promptly
      pay the same, without any demand or notice whatsoever, and that in the
      case of any extension of time of payment or renewal of any of the
      Guaranteed Obligations, the same will be promptly paid in full when due
      (whether at extended maturity, by acceleration or otherwise) in accordance
      with the terms of such extension or renewal.

            12.02. Obligations Unconditional. The obligations of the Guarantors
      under Section 12.01 hereof are absolute and unconditional, joint and
      several, irrespective of the value, genuineness, validity, regularity or
      enforceability of the obligations of the Borrowers under this Agreement or
      any other agreement or instrument referred to herein or therein, or any
      substitution, release or exchange of any other guarantee of or security
      for any of the Guaranteed Obligations, and, to the fullest extent
      permitted by applicable law, irrespective of any other circumstance
      whatsoever that might otherwise constitute a legal or equitable discharge
      or defense of a surety or guarantor, it being the intent of this Section
      12 that the obligations of the Guarantors hereunder shall be absolute and
      unconditional, joint and several, under any and all circumstances. Without
      limiting the generality of the foregoing, it is agreed that the occurrence
      of any one or more of the following shall not alter or impair the
      liability of the Guarantors hereunder, which shall remain absolute and
      unconditional as described above:

                  (i) at any time or from time to time, without notice to the
      Guarantors, the time for any performance of or compliance with any of the
      Guaranteed Obligations shall be extended, or such performance or
      compliance shall be waived;

                  (ii) any of the acts mentioned in any of the provisions of
      this Agreement or any other agreement or instrument referred to herein
      shall be done or omitted; or

                  Amendment No. 2 to Credit Agreement (5-Year)



                                      -13-


                  (iii) the maturity of any of the Guaranteed Obligations shall
      be accelerated, or any of the Guaranteed Obligations shall be modified,
      supplemented or amended in any respect, or any right under this Agreement
      or any other agreement or instrument referred to herein shall be waived or
      any other guarantee of any of the Guaranteed Obligations or any security
      therefor shall be released or exchanged in whole or in part or otherwise
      dealt with.

            The Guarantors hereby expressly waive diligence, presentment, demand
      of payment, protest and all notices whatsoever, and any requirement that
      the Administrative Agent or any Bank exhaust any right, power or remedy or
      proceed against any Borrower under this Agreement or any other agreement
      or instrument referred to herein, or against any other Person under any
      other guarantee of, or security for, any of the Guaranteed Obligations.

            12.03. Reinstatement. The obligations of the Guarantors under this
      Section 12 shall be automatically reinstated if and to the extent that for
      any reason any payment by or on behalf of any Borrower in respect of the
      Guaranteed Obligations is rescinded or must be otherwise restored by any
      holder of any of the Guaranteed Obligations, whether as a result of any
      proceedings in bankruptcy or reorganization or otherwise, and the
      Guarantors jointly and severally agree that they will indemnify the
      Administrative Agent and each Bank on demand for all reasonable costs and
      expenses (including fees of counsel) incurred by the Administrative Agent
      or such Bank in connection with such rescission or restoration, including
      any such costs and expenses incurred in defending against any claim
      alleging that such payment constituted a preference, fraudulent transfer
      or similar payment under any bankruptcy, insolvency or similar law.

            12.04. Subrogation. The Guarantors hereby jointly and severally
      agree that until the payment and satisfaction in full of all Guaranteed
      Obligations and the expiration and termination of the Commitments of the
      Banks under this Agreement they shall not exercise any right or remedy
      arising by reason of any performance by them of their guarantee in Section
      12.01 hereof, whether by subrogation or otherwise, against any Borrower or
      any other guarantor of any of the Guaranteed Obligations or any security
      for any of the Guaranteed Obligations.

            12.05. Remedies. The Guarantors jointly and severally agree that, as
      between the Guarantors and the Banks, the obligations of the Borrowers
      under this Agreement may be declared to be forthwith due and payable as
      provided in Section 9 hereof (and shall be deemed to have become
      automatically due and payable in the circumstances provided in Section 9
      hereof) for purposes of Section 12.01 hereof notwithstanding any stay,
      injunction or other prohibition preventing such declaration (or such
      obligations from


                                      -14-


      becoming automatically due and payable) as against any Borrower and that,
      in the event of such declaration (or such obligations being deemed to have
      become automatically due and payable), such obligations (whether or not
      due and payable by any Borrower) shall forthwith become due and payable by
      the Guarantors for purposes of Section 12.01 hereof.

            12.06. Instrument for the Payment of Money. Each Guarantor hereby
      acknowledges that the guarantee in this Section 12 constitutes an
      instrument for the payment of money, and consents and agrees that any Bank
      or the Administrative Agent, at its sole option, in the event of a dispute
      by such Guarantor in the payment of any moneys due hereunder, shall have
      the right to bring motion-action under New York CPLR Section 3213.

            12.07. Continuing Guarantee. The guarantee in this Section 12 is a
      continuing guarantee, and shall apply to all Guaranteed Obligations
      whenever arising.

            12.08. Rights of Contribution. The Guarantors hereby agree, as
      between themselves, that if any Guarantor shall become an Excess Funding
      Guarantor (as defined below) by reason of the payment by such Guarantor of
      any Guaranteed Obligations, each other Guarantor shall, on demand of such
      Excess Funding Guarantor (but subject to the next sentence), pay to such
      Excess Funding Guarantor an amount equal to such Guarantor's Pro Rata
      Share (as defined below and determined, for this purpose, without
      reference to the properties, debts and liabilities of such Excess Funding
      Guarantor) of the Excess Payment (as defined below) in respect of such
      Guaranteed Obligations. The payment obligation of a Guarantor to any
      Excess Funding Guarantor under this Section 12.08 shall be subordinate and
      subject in right of payment to the prior payment in full of the
      obligations of such Guarantor under the other provisions of this Article
      and such Excess Funding Guarantor shall not exercise any right or remedy
      with respect to such excess until payment and satisfaction in full of all
      of such obligations.

                  For purposes of this Section 12.08, (i) "Excess Funding
      Guarantor" means, in respect of any Guaranteed Obligations, a Guarantor
      that has paid an amount in excess of its Pro Rata Share of such Guaranteed
      Obligations, (ii) "Excess Payment" means, in respect of any Guaranteed
      Obligations, the amount paid by an Excess Funding Guarantor in excess of
      its Pro Rata Share of such Guaranteed Obligations and (iii) "Pro Rata
      Share" means, for any Guarantor, the ratio (expressed as a percentage) of
      (x) the amount by which the aggregate present fair saleable value of all
      properties of such Guarantor (excluding any shares of stock of any other
      Guarantor) exceeds the amount of all the debts and liabilities of such
      Guarantor (including contingent, subordinated, unmatured


                                      -15-


      and unliquidated liabilities, but excluding the obligations of such
      Guarantor hereunder and any obligations of any other Guarantor that have
      been Guaranteed by such Guarantor) to (y) the amount by which the
      aggregate fair saleable value of all properties of all of the Guarantors
      exceeds the amount of all the debts and liabilities (including contingent,
      subordinated, unmatured and unliquidated liabilities, but excluding the
      obligations of the Guarantors under this Section 12) of all of the
      Guarantors, determined (A) with respect to any Guarantor that is a party
      hereto on the date hereof, as of the date hereof, and (B) with respect to
      any other Guarantor, as of the date such Guarantor becomes a Guarantor
      hereunder.

            12.09. General Limitation on Guarantee Obligations. In any action or
      proceeding involving any state corporate law, or any state or Federal
      bankruptcy, insolvency, reorganization or other law affecting the rights
      of creditors generally, if the obligations of any Guarantor under Section
      12.01 hereof would otherwise, taking into account the provisions of
      Section 12.08 hereof, be held or determined to be void, invalid or
      unenforceable, or subordinated to the claims of any other creditors, on
      account of the amount of its liability under Section 12.01 hereof, then,
      notwithstanding any other provision hereof to the contrary, the amount of
      such liability shall, without any further action by such Guarantor, any
      Bank, the Administrative Agent or any other Person, be automatically
      limited and reduced to the highest amount that is valid and enforceable
      and not subordinated to the claims of other creditors as determined in
      such action or proceeding."

            2.18. Exhibits and Schedules.

            (i) Exhibit E to the Credit Agreement is hereby replaced in its
entirety with Exhibit E attached to this Amendment No. 2, and each reference in
the Credit Agreement to such Exhibit E shall be deemed to refer to the Exhibit E
attached to this Amendment No. 2.

            (ii) Schedule 8.05(j) attached to this Amendment No. 2 shall be
deemed attached to and made a part of the Credit Agreement.

            Section 3. Addition of Borrowers and Guarantors. Mid Ocean Limited
hereby agrees to become and be a Guarantor under, and each of XL Capital, XL
Insurance and XL Mid Ocean hereby agrees to become and be a Borrower and a
Guarantor under, and as defined, in the Credit Agreement (as amended hereby) and
agrees to be bound by the terms of the Credit Agreement (as so amended) as a
Guarantor and/or Borrower, as the case may be.
