Second Amended and Restated Agreement for the Sale and Purchase of Winterthur
International

This second amended and restated Agreement is made as of 15 February 2001

Between:

(1)  WINTERTHUR SWISS INSURANCE COMPANY a joint-stock company incorporated under
     the laws of Switzerland (registered number CH-020.3.928.827-5) whose
     registered office is at General Guisan-Strasse 40, PO Box 357, CH-8401
     Winterthur, Switzerland ("Winterthur"); and

(2)  XL INSURANCE LTD a company incorporated under the laws of Bermuda whose
     registered office is at XL House, One Bermudiana Street, Hamilton HM 11,
     Bermuda ("XL Insurance").

Whereas:

(A)  Winterthur and the other Sellers carry on amongst other things the
     Operations.

(B)  Winterthur has agreed to sell and to procure that the other Sellers sell
     and XL Insurance has agreed to purchase and to procure that the other
     Purchasers purchase the Operations as a going concern at Completion.

(C)  The parties intend to transfer the Operations at Completion with economic
     effect as from the Effective Time of 1 July 2001. The Purchase Price is the
     Pro-forma Net Asset Value at 30 June 2001 as determined in accordance with
     US GAAP plus the Premium. The transfer will be by share transfer, by
     portfolio transfer and/or by reinsurance arrangements. In certain
     circumstances the parties may agree before Completion to adjust the method
     of transfer.

(D)  If all the conditions precedent to the transfer of the Key Operations are
     satisfied, but not to the transfer of the other Operations, the parties
     intend Completion to occur, the Key Operations to transfer legally and
     beneficially, the economic value and management control and beneficial
     interest in the other Operations to transfer to the maximum extent
     permitted under Applicable Laws or as otherwise provided herein, and the
     whole Purchase Price to be paid.

(E)  The Pro-forma Net Asset Value at 30 June 2001 will be calculated, inter
     alia, by reference to an Initial Net Reserves Amount. On the End Date of 30
     June 2004 the Seasoned Net Reserves Amount shall be calculated, and a
     balancing payment determined in accordance with the provisions of this
     Agreement shall be made to Winterthur or XL Insurance as appropriate to
     reflect the Seasoned Net Reserves Amount compared to the Initial Net
     Reserves Amount (which balancing payment is intended to have the economic
     effect (ignoring the time value of money) of the parties sharing in any
     redundancy or deficiency in accordance with this Agreement).

(F)  This second amended and restated Agreement amends, restates and supersedes
     an agreement relating to the sale and purchase of Winterthur International

          follows: (xxix) in relation to any Leasehold Property in accordance
          with the terms and provisions contained in the relevant Lease
          Agreement and in accordance with any matter affecting any reversionary
          interest (notwithstanding any prohibition on granting such a licence
          in any Lease Agreement); and

          (xxx) and in relation to any Freehold Property all parties shall act
               reasonably in co-operating with the others in relation to that
               occupation.


     2.4.16 Where any Third Party Consent is required to vest any Freehold
          Property or Leasehold Property in the relevant Purchaser and such
          consent is not to be unreasonably withheld by the third party from
          whom consent is required and such consent has not been obtained within
          six (6) months after Completion (subject to extension as agreed by the
          parties) Winterthur shall or shall procure that the relevant Seller
          (or any other relevant party) shall apply to court (or other relevant
          tribunal) for a declaration that the relevant third party is
          unreasonably withholding consent and if and when such declaration is
          obtained the relevant parties shall enter into such documents in
          accordance with Schedule 10 to vest the relevant Freehold Property or
          Leasehold Property in the relevant Purchaser.

     2.4.17 If the relevant Third Party Consent in relation to any Freehold
          Property or Leasehold Property has not been obtained within nine (9)
          months after Completion (subject to extension as agreed by the
          parties) or the Freehold Property or Leasehold Property has not vested
          in the relevant Purchaser for any other reason (other than as provided
          for in Clause 2.1.16) XL Insurance may by 10 Business Days' notice in
          writing to Winterthur: (xxxi) require the Sellers to complete (or
          procure the completion of and Winterthur shall procure the completion
          of) any documents or do any thing or act necessary (save to the extent
          that such thing or act would give rise to a breach of contract or a
          contravention of law) to vest the relevant Freehold Property or
          Leasehold Property in the relevant Purchaser in accordance with
          Schedule 10 notwithstanding that the requisite Third Party Consent has
          not been obtained and the parties shall complete (or procure the
          completion of) all arrangements necessary to vest the Freehold
          Property or Leasehold Property in the relevant Purchaser within 30
          Business Days of the date of such notice failing which the relevant
          Purchaser may at any time thereafter terminate the relevant
          Purchaser's licence to occupy any Freehold Property or Leasehold
          Property contemplated by Clause 2.1.15 by notice in writing to the
          relevant Seller and the Purchasers shall have no further Liabilities
          hereunder (including, without limitation, under Clause 2.1.14 and
          Clause 2.2.2) with respect to such Freehold Property or Leasehold
          Property; or

          (xxxii) at any time thereafter terminate any licence to occupy any
               Freehold Property or Leasehold Property implied by Clause 2.1.15
               on 30 Business Days' notice

                                      -20-

               to the relevant Seller and the Purchasers shall have no further
               Liabilities hereunder (including, without limitation, under
               Clause 2.1.14 and Clause 2.2.2) with respect to such Freehold
               Property or Leasehold Property.


     2.4.18 Where at Completion any Property or Additional Property vests in any
          Purchaser pursuant to the sale of Shares under this Agreement and any
          member of the Winterthur Group is still in occupation of part of that
          Property or Additional Property but a Licence to Occupy or Consent has
          not been obtained in accordance with Part 1C of Schedule 10, then:
          (xxxiii) Clause 2.1.10 shall continue to apply (and for the avoidance
          of doubt all other Clauses of this Agreement relating to
          post-Completion obligations shall continue to apply mutatis mutandis
          in relation to the Property and Additional Property); and

          (xxxiv) Clauses 2.1.19, 2.1.20, 2.1.21 and 2.1.22 shall apply.


     2.4.19 Where Clause 2.1.18 applies to any Property or Additional Property,
          then this Clause and Clauses 2.1.20 to 2.1.22 (inclusive) shall apply
          to that Property or Additional Property and the definitions of
          "Leasehold Property" and "Freehold Property" shall for those purposes
          include any leasehold property or freehold property respectively
          comprising any Property or Additional Property and any reference to
          "Licence to Occupy" or "Consent" means a Licence to Occupy or Consent
          as those terms are defined in Part 1C of Schedule 10 of this
          Agreement.

     2.4.20 From Completion until such time as any Consent is obtained and any
          Licence to Occupy is entered into in favour of any member of the
          Winterthur Group such member shall be entitled to occupy the Property
          or Additional Property as a licensee on such reasonable terms as the
          relevant parties shall agree and such member shall pay (and Winterthur
          shall procure that such member pays) on and from Completion until such
          time as any Licence to Occupy is completed or any licence contemplated
          by this clause is terminated in accordance with Clause 2.1.21 a fee
          equal to the proper and reasonable proportion attributable to the
          relevant member of the Winterthur Group's use and occupation of any
          Property or Additional Property as determined by the relevant
          Purchaser (acting reasonably) of: (xxxv) all rents, insurance premiums
          and service charges and other amounts properly payable in respect of
          any Leasehold Property under the relevant Lease Agreements; and

          (xxxvi) all rates, electricity, phone charges and other general
               outgoings (excluding taxes of any nature other than VAT properly
               payable on any such outgoings) in respect of any Freehold
               Property.


     2.4.21 (Subject to Clause 2.1.22) following the parties' using all
          reasonable endeavours to procure any Consent in accordance with Clause
          2.1.10 if any third party refuses to grant any Consent for any
          Leasehold Property or Freehold Property in relation to any Licence to
          Occupy or at any time serves notice on the relevant Purchaser
          requiring the relevant Purchaser to cease all sharing of occupation
          and possession of any Leasehold Property or Freehold Property with any
          member of the Winterthur Group then: (xxxvii) the relevant Purchaser
          shall be entitled to serve notice on any member of the Winterthur
          Group terminating the licence contemplated by Clause 2.1.20; and

          (xxxviii) any such member of the Winterthur Group shall (and
               Winterthur shall procure that such member shall) upon the service
               of any notice under Clause 2.1.21 forthwith vacate the relevant
               Leasehold Property or Freehold Property causing as little
               inconvenience as possible to the relevant Purchaser and making
               good any damage thereby caused.

                                      -21-

     2.4.22 If any Consent is required pursuant to Clause 2.1.18 and such
          consent is not to be unreasonably withheld, then upon receiving
          written notice from the Winterthur Group the Purchaser shall or shall
          procure that (at the cost of the Winterthur Group) an application to
          court or other relevant tribunal is made for a declaration that the
          relevant third party is unreasonably withholding consent.

               Time;

          (xlv) any Taxation liability of any Business Seller; and

          (xlvi) all Liabilities relating to each Freehold Property and

               pursuant to the provisions of Clause 2.1.17,

     and shall promptly pay the Liabilities and settle the claims referred to in
     Clauses 2.2.1(i), (ii), (iii), (iv), (v), (vi), (vii) and/or (viii) as
     appropriate.


     2.5.2 Subject as expressly provided elsewhere in this Agreement, the
          relevant Purchaser shall be responsible after the Effective Time for:
          (xlvii) all Liabilities arising under the Policies which have been

          (li) any Liabilities which relate to the Business Assets which are
               disclosed to XL Insurance before Completion, are readily
               quantifiable and are stated as Liabilities in the Completion
               Balance Sheet,

     (together the "Assumed Liabilities") and shall promptly pay the Liabilities
     and settle the claims referred to in Clauses 2.2.2(i), (ii), (iii), (iv)
     and/or (v) as appropriate.


     2.5.3 The Assumed Liabilities are assumed by the relevant Purchaser subject
          to and so that such Purchaser to the extent permitted by Applicable
          Laws shall have and be entitled to the benefit of the same rights,
          powers, remedies, claims, defences, obligations, conditions and
          incidents (including without limitation rights of set-off and
          counterclaim) as the relevant Business Seller enjoyed. The Purchasers'
          sole responsibility in respect of any Policies or Retrocession
          Contracts relating to any Business to which Clause 2.7 applies shall
          be to perform their obligations under the relevant Reinsurance
          Agreement as provided in Clause 2.

2.6  Indemnities

     2.6.1 XL Insurance agrees with Winterthur (for itself and in trust for each
          member of the Winterthur Group) that, subject as expressly provided
          elsewhere in this Agreement, XL Insurance shall and shall procure that
          any other Purchaser shall indemnify and hold harmless and keep
          indemnified and held harmless the Sellers and each member of the
          Winterthur Group and their respective directors, officers, agents,
          employees and Associated Companies against:

          (lii) all Assumed Liabilities including for the avoidance of doubt any
               such Assumed Liability which is or is deemed to be or becomes a
               Liability of Winterthur and/or any other Seller by virtue of any
               Applicable Laws; and

          (liii) any Losses which Winterthur and/or any other Seller may suffer
               by reason of any Purchaser's failure to comply with its
               obligations under Clause 2.2.2 or otherwise by reason of
               Winterthur and/or any other Seller taking any reasonable action
               to avoid, resist or defend against any Assumed Liability.


     2.6.2 Winterthur agrees with XL Insurance (for itself and in trust for each

          and

          (lv) any Losses which XL Insurance and/or any other Purchaser may
               suffer by reason of any Seller's failure to comply with its
               obligations under Clause 2.2.1 or otherwise by reason of XL
               Insurance and/or any other Purchaser taking any reasonable action
               to avoid, resist or defend against any Liability.


2.7  Pre-emption rights Winterthur shall procure that on or prior to Completion
     any and all rights of pre-emption over or other restrictions on transfer
     applying in relation to the Shares are waived irrevocably by the persons
     entitled thereto.


2.8  Identity of Purchasers and Sellers

     2.8.1 XL Insurance has proposed that those companies or details of types of
          companies (such details to include jurisdiction of incorporation and
          such other details as Winterthur may reasonably request) referred to
          in paragraph 6 of Part 1 of Schedule 2 will purchase the Shares and/or
          Business Assets and to assume the Assumed Liabilities or any part
          thereof.

     2.8.2 Notwithstanding Clause 2.5.1 XL Insurance shall be entitled to change
          its proposals referred to in Schedule 2 and nominate by notice in
          writing to Winterthur at any time up to 10 Business Days prior to the
          expected Completion Date one or more Purchasers (being in each case a
          subsidiary of XL Insurance whose obligations to any Seller under this
          Agreement or any Local

                                      -23-

          Agreement shall be guaranteed by XL Insurance in the terms set out in
          Clause 17) to purchase any of the Shares and/or Business Assets and to
          assume the Assumed Liabilities or any part thereof subject to
          obtaining Winterthur's prior consent to such nomination (such consent
          not to be unreasonably withheld or delayed and the reasons for the
          withholding of such consent having been provided in writing to XL
          Insurance along with any withholding of consent). For the purpose of
          this Clause 2.5.2 consent shall only be considered to have been
          reasonably withheld if it has been withheld for a material financial,
          regulatory or other bona fide reason of the Sellers.

     2.8.3 The parties shall procure that any Purchaser referred to in Schedule
          2 or nominated (Winterthur having consented to such nomination under
          Clause 2.5.2) under this Clause 2.5 and any Seller shall become a
          party to this Agreement by entering into a Deed of Adherence.

2.9  Local Agreements

     2.9.1 Winterthur shall or shall procure that the relevant Sellers shall and
          XL Insurance shall or shall procure that the relevant Purchasers shall
          enter into such Local Agreements in individual jurisdictions as may be
          necessary or deemed (by both Winterthur and XL Insurance) to be
          desirable to give effect to the transfer of the Operations in such
          jurisdictions on Completion or such earlier date as may be agreed
          between Winterthur and XL Insurance. To the extent that the provisions
          of this Agreement are inconsistent with or additional to the
          provisions of a Local Agreement, the provisions of this Agreement
          shall prevail and Winterthur and XL Insurance shall procure that the
          provisions of the relevant Local Agreement are adjusted so far as
          permissible under the laws of the relevant jurisdiction to the extent
          necessary to give effect to the provisions of this Agreement and/or
          that the relevant Seller and the relevant Purchaser comply with the
          provisions of this Agreement as though they were bound by such
          provisions in place of the provisions of the relevant Local Agreement,
          save in relation to any Local Agreement to which the US Business
          Seller is a party or where Winterthur and XL Insurance otherwise agree
          in writing that such Local Agreement shall expressly override the
          provisions of this Agreement. For the avoidance of doubt, to the
          extent that any Local Agreement is otherwise terminated or would not
          otherwise apply, the rights and the obligations of the parties to such
          Local Agreement, as contemplated by this Agreement, shall in no way be
          amended, modified, waived or otherwise affected. 2.9.2 For the
          avoidance of doubt in relation to the US Business Seller the
          provisions of any Local Agreement to which it is a party shall in no
          way amend, modify, waive or otherwise affect any of the rights or
          obligations of the parties to this Agreement, as between the parties
          to this Agreement.

     2.9.3 Notwithstanding the above, any provision in the Service Level
          Agreement in relation to Supply Tax (as defined in the Service Level
          Agreement) shall apply in accordance with its terms whether or not
          such provision is consistent with the terms of this Agreement.


2.10 Portfolio Transfers

     To the extent that paragraph 2 of Part 1 of Schedule 2 envisages the
     transfer of a Portfolio (comprising Policies and related Retrocession
     Contracts) to a Purchaser and it is not practicable for whatever reason to
     effect such transfer at Completion Winterthur and XL Insurance shall or
     shall procure that the relevant Seller and relevant Purchaser enter into
     the Interim Arrangements. XL Insurance may propose changes to the Interim
     Arrangements at any time up to 5 Business Days prior to the expected
     Completion Date subject to obtaining Winterthur's prior consent to such
     change (such consent not to be unreasonably withheld or delayed). The
     Sellers shall provide to the relevant Purchaser such information as it may
     reasonably request at any time after the date of this Agreement in relation
     to the Policies and the Retrocession Contracts comprised in any Portfolio
     (including as to whether or not the other parties to such Policies or
     Retrocession Contracts have consented or have the right to object to a
     transfer of the same to the Purchaser).


2.11 Service Level Agreements and Other Agreements The parties shall use
     reasonable endeavours to negotiate in good faith and enter into the
     following agreements at Completion namely:


     2.11.1 Service Level Agreements similar to those service level agreements
          currently existing (unless the same are to be continued after
          Completion by agreement between the parties) or such

                                      -24-

          further agreements as may be required between any member of the
          Winterthur Group and any of the Operations after Completion in
          relation to those inter-dependencies which are referred to in the
          Disclosure Letter and in accordance with the principles set out in
          paragraph 4 of Part 1 of Schedule 2 and any additional Service Level
          Agreements which may be required pursuant to the provisions of Clauses
          2.1.5 and 2.1.6;

     2.11.2 the Life and Pensions Distribution Agreement in accordance with the
          principles set out in paragraph 4.2 of Part 1 of Schedule 2;

     2.11.3 quota share reinsurance agreements in accordance with the principles
          set out in paragraph 2.2.1 of Part 1 of Schedule 2;

     2.11.4 fronting or other similar agreements or arrangements in accordance
          with the principles set out in Part 1 of Schedule 2;

          arrangements in accordance with the principles set out in Part 1 of
          Schedule 2;

     2.11.6 the Trade Mark Licence Agreement in accordance with the principles
          set out in Clause 15.6; and

     2.11.7 such other types of agreements as may be necessary or appropriate to
          give effect to any of the principles set out in this Agreement.

     2.12 Structural Changes Winterthur and XL Insurance shall give appropriate
          and due consideration to each other's requests to optimise the
          structure of the reorganisations referred to in Clause 5.1.4 or the
          Transfer of Operations.

3.   Purchase Price

     3.4  Calculation of Purchase Price

     3.4.1 The aggregate consideration for the purchase of the Operations shall
          be an amount equal to the sum (such sum being hereinafter referred to
          as the "Purchase Price") of: (lvi) the Pro-forma Net Asset Value of
          the Operations as at 30 June 2001 (as determined and adjusted pursuant
          to Schedule 5); and

          (lvii) USD53 million (the "Premium") subject to adjustment pursuant to
               Clause 3.1.5.

     3.4.2 At Completion XL Insurance shall or shall procure that other
          Purchasers as appropriate pay to Winterthur or other Sellers as
          appropriate an aggregate amount which is equal to the sum (such sum
          being hereinafter referred to as the "Preliminary Purchase Price") of:
          (lviii) the Pro-forma Net Asset Value of the Operations as at 31
          December 2000 (as determined pursuant to Schedule 5); and

          (lix) the Premium.

     3.4.3 The Preliminary Purchase Price and the Purchase Price shall be paid
          in accordance with the Payment Agreement.

     3.4.4 Following Completion the Pro-forma Net Asset Value of the Operations
          as at 30 June 2001 shall be determined in accordance with Schedule 5.

     3.4.5 If the Purchase Price as so finally determined exceeds the
          Preliminary Purchase Price, XL Insurance shall or shall procure that
          other Purchasers as appropriate shall pay to Winterthur or any other
          Seller an amount equal to such excess. If the Preliminary Purchase
          Price exceeds the Purchase Price as so finally determined, Winterthur
          shall or shall procure that other Sellers as appropriate shall refund
          to XL Insurance or any other Purchaser a portion of the Preliminary
          Purchase Price being an amount equal to such excess (and, if relevant,
          together with an additional amount equal to the amount by which the
          Pro-forma Net Asset Value is less than zero). If the Pro-forma Net
          Asset Value as at 30 June 2001 ("Closing NAV") is less than 80% of the
          Pro-forma Net Asset Value as at 30 September 2000

                                      -25-

          ("Opening NAV"), the Premium shall be adjusted as follows and
          Winterthur shall pay to XL Insurance the difference between the
          Preimium under Clause 3.1.1 and the adjusted Premium calculated in
          accordance with the table below:

          Closing NAV                                  Premium (USD million)

          1.  Greater than or equal to 80% of          50 + 3 = 53
              Opening NAV

          2.  Greater than zero and less than          {50 x Closing NAV} + 3
                                                             ------------
              80% of Opening NAV                             Opening NAV

          3.  Less than or equal to zero               0 + 3 = 3

          The Closing NAV and Opening NAV shall be calculated on a like-for-like
          basis (including that the Closing NAV shall be calculated without
          reference to any capital contribution made by Winterthur (or any
          Associated Company other than a Group Company) to any Group Company
          after 30 September 2000).


          The payment of any amounts due under this Clause 3.1.5 shall be made
          within five Business Days of the date on which the Purchase Price is
          so finally determined and all amounts due under this Clause 3.1.5
          shall include interest thereon (from and including the Completion Date
          until the date such payment is made) at a non-compounding rate per
          annum of 0.5 per cent above the Base Rate.

     3.4.6 Without otherwise affecting any provision of this Agreement, the
          parties acknowledge that XL Insurance and the other Purchasers may
          credit, against the cash payment for the Purchase Price and
          Preliminary Purchase Price, any purchase price paid under any Local
          Agreement.

3.5  Method of Payment

     Wherever in this Agreement provision is made for payment by one party to
     another such payment shall be made in US Dollars and subject to the terms
     of the Payment Agreement be effected by crediting the account specified in
     the Payment Accounts Details of the party entitled to payment by wire
     transfer of immediately available funds on or before the due date for
     payment unless the payee by notice in writing to the payer not later than
     three Business Days prior to the due date for payment elects to be paid by
     banker's draft drawn on any international bank reasonably acceptable to the
     payer and having an office in London, Zurich, the United States or Bermuda.
     Payment of such sum shall be a good discharge to the payer (and those on
     whose behalf such payment is made) of its (and their) obligation to make
     such payment and the payer (and those on whose behalf such payment is made)
     shall not be obliged to see to the application of the consideration as
     between the relevant Sellers in the case of a payment to Winterthur or as
     between the relevant Purchasers in the case of a payment to XL Insurance.

                                      -26-

3.6  Allocation of Purchase Price

     3.6.1 The Purchase Price shall be allocated to the Operations in accordance
          with the principles set out in this Clause 3.3 as the parties shall
          mutually agree. Unless otherwise agreed in writing by the parties, the
          parties shall as soon as practicable after the date of this Agreement
          instruct their financial advisors Morgan Stanley in the case of the
          Purchasers and Credit Suisse First Boston in the case of the Sellers
          to provide (by the time contemplated by the Payment Agreement) their
          opinion and study as to the appropriate allocation of the Purchase
          Price and shall include in such opinions and study their opinion as to
          what portion of the Purchase Price shall be allotted to the benefit of
          the use of the name "Winterthur International" pursuant to Clause 15
          and to the restrictive covenants referred to in Clause 16 as they
          should deem appropriate. Notwithstanding the above in the event that
          the above financial advisors are unable to agree and recommend the
          appropriate allocation of the Purchase Price then the parties shall
          jointly instruct such internationally renowned financial and
          investment banking firm as may be selected by the parties or failing
          agreement between them by the President of the Institute of Chartered
          Accountants of England and Wales to provide their own independent
          opinion and study as to the appropriate allocation of the Purchase
          Price.

     3.6.2 All parties agree to the extent permitted by Applicable Laws to adopt
          the final allocation reached in accordance with Clause 3.3.1 (as may
          be further adjusted) for all purposes, including Tax purposes.

3.7  VAT

     3.7.1 General

          (lx) The parties agree that any VAT chargeable on the supply or
               supplies for which any sums payable (or other consideration
               provided) by any Purchaser to any Seller pursuant to this
               Agreement or any Local Agreement or any document pursuant to
               which any estate or interest or title is transferred to or
               otherwise vested in XL Insurance or any other Purchaser are the
               whole or part of the consideration for VAT purposes shall be
               borne by Winterthur or the relevant Seller and (without prejudice
               to the generality of the foregoing) any such sums payable (or
               other consideration provided) shall be inclusive of any VAT which
               may be chargeable on the supply or supplies for which such sum or
               other consideration (or any part thereof) is the whole or part of
               the consideration for VAT purposes and s.89 of the VATA shall not
               apply to affect the amount of such sum or other consideration.
               For the avoidance of doubt, this paragraph shall not apply to VAT
               due on services provided under the Service Level Agreement in
               respect of which Clause 7 of that Agreement shall apply.

          (lxi) The parties intend that the Businesses shall be sold as a going
               concern for VAT purposes and shall procure that in each relevant
               jurisdiction Winterthur (which in this Clause 3.4 shall include
               any relevant Seller) and XL Insurance shall give notice of such
               sale to the relevant Tax authorities as required by Applicable
               Laws.


     3.7.2 Records: Each Seller may so far as it is able prior to Completion in
          respect of a Relevant Transfer of Operations obtain a direction from
          the relevant Taxation authority detailing provisions for the retention
          and preservation by it of any VAT records relating to the Businesses
          and where such directions are obtained each Seller undertakes to
          preserve any such records in such a manner and for such period as may
          be required by Applicable Laws and will produce on demand information
          from these records to the relevant Purchaser and/or any relevant
          Taxation authority and afford the relevant Purchaser access to such
          records for the purpose of inspecting and making copies of the same if
          the relevant Purchaser demonstrates that such production or access is
          necessary for its VAT affairs.

     3.7.3 Going Concern: To the extent that any jurisdiction in which any of
          the Businesses is carried on provides for relief or exemption from VAT
          on the transfer of a business or treats such a transaction as being
          non-taxable or giving rise to no supply for VAT purposes XL Insurance
          and Winterthur shall use all reasonable endeavours (including for the
          avoidance of doubt the making of an election or application in respect
          of VAT to any Taxation authority) to secure such treatment.

                                      -27-

3.8  Adjustments to Purchase Price

     If any payment is made by any party to another party in respect of any
     claim against any party for any breach of or otherwise under the terms of
     this Agreement, Tax Deed or any Local Agreement the payment shall be made
     by way of adjustment of the Purchase Price paid by XL Insurance or other
     Purchasers as appropriate for the Operations pursuant to Clause 3.1 and the
     Purchase Price shall be deemed to have been reduced or increased as
     appropriate by the amount of such payment.

3.9  Breach of Agreement known prior to determination of Completion Balance
     Sheet

     In the event that there has been a breach of this Agreement by any Seller
     including without limitation a breach of any of the Warranties under Clause
     8 (at whatever date given) then to the extent that such breach is known
     prior to the date on which the Completion Balance Sheet is finally
     determined the parties shall use their reasonable efforts to agree an
     appropriate adjustment to the Net Asset Value of the relevant Operations to
     be set out in the Completion Balance Sheet to ensure that the financial and
     other conditions of the relevant Operations are fairly reflected in such
     Completion Balance Sheet in the light of such breach (whether or not such
     circumstance needs to be reflected in such Completion Balance Sheet for the
     purpose of US GAAP). In the event that the parties do not agree any such
     adjustment the Reporting Accountants shall make whatever adjustment they
     consider to be appropriate thereto on the basis of the above criteria and
     in accordance with the timetable set out in Schedule 5.

3.10 Adjustment to amounts paid under Clause 3.6

     3.10.1 In the event that there has been a breach of this Agreement by any
          Seller including without limitation a breach of any of the Warranties
          under Clause 8 (at whatever date given) then to the extent that such
          breach is known prior to the date on which the Completion Balance
          Sheet is finally determined then Winterthur shall or shall procure
          that other Sellers as appropriate subject as below pay to XL Insurance
          or other Purchasers as appropriate on demand an amount equal to all
          Losses incurred by any Purchaser or any Group Company in respect of
          any Business or Operation (including without limitation each Loss
          incurred as a result of defending or settling a claim alleging such
          liability) in respect of such breach to the extent that such Losses
          exceed the amount of any adjustment to the Net Asset Value of the
          Operations in relation to such breach made pursuant to Clause 3.6.

     3.10.2 In the event that there has been a breach of this Agreement by any
          Seller including without limitation a breach of any of the Warranties
          under Clause 8 (at whatever date given) then to the extent that such
          breach is known prior to the date on which the Completion Balance
          Sheet is finally determined but the level of any adjustment made in
          the Net Asset Value of the Operations made in the Completion Balance
          Sheet pursuant to Clause 3.6 exceeds the aggregate amount of all
          Losses incurred by any Purchaser or any Group Company in respect of
          any Business or Operation (including without limitation each Loss
          incurred as a result of defending or settling a claim alleging such
          Liability) in respect of such breach, XL Insurance shall or shall
          procure that other Purchasers as appropriate pay to Winterthur or
          other Sellers as appropriate on demand an amount equal to such excess.

4.   Net Reserves

     4.4  Review of calculation of Net Reserves at 31 December 2000 In
          connection with the preparation of the 31.12.2000 Financial Statements
          including the calculation of the net reserves of the Operations
          Winterthur shall and shall procure that each of the other Sellers
          (both before and after Completion) and each of the Group Companies
          (before Completion) shall:

          4.4.1 keep up-to-date and make available to XL Insurance, XL
               Insurance's Accountants and XL Insurance's Actuary their books,
               records, contracts and agreements relating to the Operations
               during normal business hours; and

          4.4.2 co-operate with them with regard to their review thereof and
               give them the opportunity to consult with Winterthur and
               Winterthur's Accountants and Winterthur's Actuary.

     Winterthur agrees insofar as it is reasonable to do so to make available
     the services of the relevant Associated Companies of Winterthur and
     Winterthur's Accountants and Winterthur's Actuary to assist XL Insurance,
     XL Insurance's Accountants and XL Insurance's Actuary to undertake the
     review
                                      -28-

     contemplated by this Clause 4.1. For the avoidance of doubt the fees and
     expenses of XL Insurance's Accountants and XL Insurance's Actuary in
     connection with their review contemplated by this Clause 4.1 shall be for
     the account of XL Insurance.


4.5  Determination of Seasoned Net Reserves Amount

        4.5.1     Subject to Clause 18.4 from and after Completion and until the
                  End Date XL Insurance shall make available to Winterthur,
                  Winterthur's Accountants and Winterthur's Actuary during
                  normal business hours:

          (lxii) all reserves studies prepared by or on behalf of XL Insurance
               to the extent relating to Relevant Operations; and

          (lxiii) all auditor's letters to management to the extent relating to
               net claims subject to the Initial Net Reserves Amount which have
               been completed by or on behalf of XL Insurance during such
               period.


     4.5.2 Within 30 Business Days following the End Date XL Insurance shall
          deliver to Winterthur a written statement setting forth in reasonable
          detail its calculation of the Seasoned Net Reserves Amount (the
          "Seasoned Net Reserves Statement").

     4.5.3 In order to enable Winterthur, Winterthur's Accountants and
          Winterthur's Actuary to review the Seasoned Net Reserves Statement, XL
          Insurance shall keep up-to-date and make available to Winterthur,
          Winterthur's Accountants and Winterthur's Actuary its books, records,
          contracts and agreements relating to the Relevant Operations during
          normal business hours and co-operate with them with regard to their
          review of the Seasoned Net Reserves Statement. XL Insurance agrees
          insofar as it is reasonable to do so to make available the services of
          the employees of the relevant Associated Companies of XL Insurance to
          assist Winterthur, Winterthur's Accountants and Winterthur's Actuary
          to undertake the matters contemplated by this Clause 4.2. XL Insurance
          shall procure that after the preparation of the Seasoned Net Reserves
          Statement, XL Insurance's Accountants and XL Insurance's Actuary shall
          give Winterthur, Winterthur's Accountants and Winterthur's Actuary
          access to XL Insurance's Accountants' and XL Insurance's Actuary's
          working papers and files (with the right to take copies at
          Winterthur's expense, subject to Winterthur entering into an
          acceptable confidentiality undertaking) and personnel which or who are
          (and only to the extent) relevant to the review of the Seasoned Net
          Reserves Statement by Winterthur, Winterthur's Accountants and
          Winterthur's Actuary subject to Winterthur providing or procuring the
          provision of a hold harmless undertaking to XL Insurance's Accountants
          and XL Insurance's Actuary.

     4.5.4 Within 30 Business Days of receipt by Winterthur of the Seasoned Net
          Reserves Statement Winterthur may give written notice to XL Insurance
          stating that it disagrees with the Seasoned Net Reserves Statement,
          together with reasons for the disagreement in reasonable detail and
          quantifying the amount of such disagreement (for the purpose of this
          Clause 4.2 the "Winterthur Disagreement Notice"). In the absence of
          such notice within such period, the Seasoned Net Reserves Statement
          shall be final and binding on the parties for all purposes.

     4.5.5 If Winterthur gives a valid Winterthur Disagreement Notice within
          such 30 Business Days Winterthur and XL Insurance shall attempt in
          good faith to reach agreement in respect thereto. If they reach
          agreement then the agreed amount shall be fully and conclusively the
          Seasoned Net Reserves Amount for the purpose of this Agreement and if
          they are unable to do so within 10 Business Days of receipt by XL
          Insurance of the Winterthur Disagreement Notice then either Winterthur
          or XL Insurance may by notice in writing to the other require that the
          calculation of the Seasoned Net Reserves Amount be referred to the
          Independent Actuary (an "Actuary Appointment Notice"). Within 10
          Business Days of receipt by a party of the Actuary Appointment Notice
          each of Winterthur and XL Insurance shall give written notice to the
          other and to the Independent Actuary of its proposed Seasoned Net
          Reserves Amount.

     4.5.6 The Independent Actuary shall be a member of the Casualty Actuarial
          Society ("CAS") or a Fellow of the Institute of Actuaries ("FIA") and
          shall be instructed to independently determine the Seasoned Net
          Reserves Amount in accordance with the principles and standards of
          practice of the CAS or the FIA as the case may be and the American
          Academy of Actuaries

                                      -29-

          and to make its determination as soon as is reasonably practicable.
          The procedures of the Independent Actuary shall be determined by the
          Independent Actuary, but shall:

          (lxiv) give the parties a reasonable opportunity to make written and
               oral representations to them;

          (lxv) require that the parties supply each other with a copy of any
               written representations at the same time as they are made to the
               Independent Actuary; and

          (lxvi) permit each party to be present while oral submissions are
               being made by any other party.

     4.5.7 The determination of the Independent Actuary shall be made in writing
          and sent to the parties at such time as it shall determine. The
          Independent Actuary shall act as an expert and not as an arbitrator
          and his or her determination shall be final and binding on the parties
          as provided in Clause 4.2.8.

     4.5.8 If the Seasoned Net Reserves Amount as determined by the Independent
          Actuary is closer to the amount proposed by XL Insurance than the
          amount proposed by Winterthur (in each case pursuant to the last
          sentence of Clause 4.2.5) then for the purpose of this Agreement the
          Seasoned Net Reserves Amount shall be finally and conclusively deemed
          to be the amount so proposed by XL Insurance. If the Seasoned Net
          Reserves Amount as determined by the Independent Actuary is closer to
          the amount proposed by Winterthur than the amount proposed by XL
          Insurance (in each case pursuant to the last sentence of Clause 4.2.5)
          then for the purpose of this Agreement the Seasoned Net Reserves
          Amount shall be finally and conclusively deemed to be the amount so
          proposed by Winterthur.

     4.5.9 The parties shall co-operate with the Independent Actuary and comply
          with its reasonable requests made in connection with the carrying out
          of its duties under this Agreement. In particular without limitation
          XL Insurance shall keep up-to-date and subject to reasonable notice
          make available to Winterthur, Winterthur's Accountants, Winterthur's
          Actuary and the Independent Actuary its books, records, contracts and
          agreements relating to the Relevant Operations during normal business
          hours during the period from the appointment of the Independent
          Actuary down to the making of the determination by the Independent
          Actuary.

     4.5.10 Subject to Clause 4.2.11 nothing in this Clause 4.2 shall entitle a
          party or the Independent Actuary access to any information or document
          which is protected by legal professional privilege or any other legal
          obligation of confidentiality or which has been prepared by the other
          party or its accountants, actuaries and other professional advisers
          with a view to assessing the merits of any claim or argument.

     4.5.11 A party shall not be entitled by reason of Clause 4.2.10 to refuse
          to supply such part or parts of documents as contain only the facts on
          which the relevant claim or argument is based.

     4.5.12 Each party shall and shall procure that its accountants, actuaries
          and other advisers shall and shall instruct the Independent Actuary to
          keep all information and documents provided to them pursuant to this
          Clause 4.2 confidential and shall not use the same for any purpose
          except for use in connection with the matters contemplated by this
          Clause 4.

     4.5.13 The methodology for determining unallocated loss adjustment expenses
          for both the Initial Net Reserves Amount and the Seasoned Net Reserves
          Amount shall be as set out in Part 4 of Schedule 5.

4.6  Seasoned Net Reserves Payment

     4.6.1 If the Seasoned Net Reserves Amount as finally agreed or determined
          pursuant to Clause 4.2 is greater than 105 per cent of the Initial Net
          Reserves Amount Winterthur shall or shall procure that other Sellers
          as appropriate pay to XL Insurance or other Purchasers as appropriate
          within five Business Days of such agreement or determination an amount
          in US Dollars equal to 90 per cent of the difference between:

          (lxvii) the Seasoned Net Reserves Amount; and

          (lxviii) 105 per cent of the Initial Net Reserves Amount, plus
               interest thereon (from and including the End Date, to but
               excluding the date such payment is made) at a non-compounding
               rate per annum of 0.5 per cent above the Base Rate.

                                      -30-

     4.6.2 In addition to any payment required pursuant to Clause 4.3.1 if the
          Seasoned Net Reserves Amount as finally agreed or determined pursuant
          to Clause 4.2 exceeds the sum of: (lxix) the Initial Net Reserves
          Amount;

          (lxx) USD61 million; and

          (lxxi) the amount of the payment (if any) required to be made by
               Winterthur pursuant to Clause 4.3.1,

     Winterthur shall or shall procure that other Sellers as appropriate pay to
     XL Insurance or other Purchasers as appropriate within five Business Days
     of such agreement or determination an amount in US Dollars equal to such
     excess plus interest thereon (from and including the End Date to but
     excluding the date such payment is made) at a non-compounding rate per
     annum of 0.5 per cent above the Base Rate. The parties agree that the
     intention of this Clause 4.3.2 is to ensure that the Purchasers themselves
     bear no more than USD61 million of the amount by which the Seasoned Net
     Reserves Amount exceeds the Initial Net Reserves Amount.

     4.6.3 If the Seasoned Net Reserves Amount as finally agreed or determined
          pursuant to Clause 4.2 is less than 95 per cent of the Initial Net
          Reserves Amount XL Insurance shall or shall procure that other
          Purchasers as appropriate pay to Winterthur or other Sellers as
          appropriate within five Business Days of such agreement or
          determination an amount in US Dollars equal to 90 per cent of the
          difference between:

          (a)  95 per cent of the Initial Net Reserves Amount; and

          (b)  the Seasoned Net Reserves Amount,

          plus interest thereon (from and including the End Date to but
          excluding the date such payment is made) at a non-compounding rate per
          annum of 0.5 per cent above the Base Rate.

     4.6.4 To the extent that the Seasoned Net Reserves Amount is greater than
          the Initial Net Reserves Amount, XL Insurance shall also be entitled
          to receive from Winterthur an additional amount such that Winterthur
          and XL Insurance share 70:30 (Winterthur:XL Insurance) the reserves
          deterioration to the extent that: (a) it is caused by reinsurance
          being unrecoverable from a reinsurer (other than as a result of that
          reinsurer being subject to insolvency or receivership proceedings
          arising after Completion); and (b) this non-recoverability causes
          deterioration (ie Seasoned Net Reserves Amount exceeds the Initial Net
          Reserves Amount); and (c) the deterioration would otherwise be borne
          by XL Insurance under either the 5% deductible (between 100% and 105%)
          or the 10% sharing mechanism (above 105%) referred to in Clause 4.3.1
          above.

     4.6.5 If, for any reason, the Completion Financial Statements are not
          agreed by 31 December 2003, the Independent Actuary shall forthwith be
          instructed to determine the Initial Net Reserves Amount by the End
          Date, which determination shall be final and binding on the parties,
          and the parties shall cooperate with the Reporting Accountants in all
          respects in relation to such determination.

                    5.2) or prior to that date the Commission adopts a decision
                    declaring that the proposed acquisition of the Operations or

          For the purpose of this paragraph:

          (lxxv) a filing shall be deemed to be necessary if it is required by
               Applicable Laws or if XL Insurance and Winterthur agree that it
               is necessary (neither party to withhold unreasonably its
               agreement in this respect); and

          (lxxvi) a jurisdiction shall be material if it is material in the

               complete expeditiously the proposed acquisition of the Operations
               provided that XL Insurance shall not be obliged to negotiate,
               commit to and/or effect, by consent decree, hold separate order

               order or other order in any suit or proceeding that would
               otherwise have the effect of materially delaying or preventing
               the consummation of XL Insurance's acquisition of the Operations.

          own respective fees and other costs incurred in relation to any such

          obtained if conditions are accepted or undertakings given by XL
          Insurance the parties shall promptly consult each other to determine
          whether such conditions or undertakings are acceptable and consistent
          with the terms of the Transaction. For the avoidance of doubt, XL
          Insurance shall acting reasonably at all times be entitled not to
          accept any relevant condition and shall be entitled to refuse to give
          any relevant undertaking.

     5.5.3 XL Insurance hereby undertakes that it will not withdraw the

          promptly give notice to the other of the satisfaction of each
          condition as specified in Clause 5.1 and in any event within two

          Clause 5.1 are not satisfied or not deemed to have been satisfied on
          or before the date which is 12 months from

                                      -34-

          the date of this Agreement then save as expressly provided this
          Agreement shall lapse and no party shall have any claim against any
          other under it save for any claim arising from breach of the
          undertaking contained in Clause 5.2.

     5.6.2 XL Insurance may waive on its own behalf and on behalf of the other
          Purchasers in whole or in part and conditionally or unconditionally

          in writing to Winterthur.

     5.6.3 If all conditions precedent to Completion set out in this Clause 5
          shall be satisfied (or waived as provided herein) except for
          conditions applicable to Winterthur Administracao e Participacoes Ltda
          or Winterthur International Brasil Seguradora S/A (together the
          "Brazil Operations") the Purchaser agrees to waive any such
          outstanding conditions provided that it is satisfied (acting
          reasonably) that the Seller will put in place as at Completion a
          mechanism and documentation reasonably satisfactory to the Purchaser
          to ensure that: (lxxxv) the Purchaser receives the entire economic
          benefit of the relevant Group Company from the Effective Time;

          (lxxxvi) the Purchaser is given adequate management control over the
               operations of the relevant Group Company;

          (lxxxvii) the Purchaser will be indemnified in respect of any Losses
               incurred by the relevant Group Company after Completion which
               result from any failure by the Group Company to comply with the
               Purchaser's instructions pursuant to the management control
               arrangements referred to in sub-paragraph (ii) above; and

          (lxxxviii) upon satisfaction of the relevant conditions the shares in
               the relevant Group Company will be transferred to the Purchaser
               for no additional consideration,

          provided that if the Purchaser does not grant a waiver in accordance
          with this Clause 5.3.3 within 15 Business Days (or such longer time as
          the parties may agree) of receiving a reasonable proposal from the
          Seller satisfying sub-paragraphs (i) to (iv) above the Brazil
          Operations will (unless the parties otherwise agree) be deemed to be
          excluded from the Operations (and accordingly all conditions precedent
          shall be deemed to be satisfied) and the definition of Excluded
          Operations shall be extended to include the Brazil Operations.

               or Purchaser; and

          6.4.14 not do or omit to do anything which would render any of the

          for Completion ) XL Insurance shall be entitled by notice to
          Winterthur delivered prior to Completion to terminate this Agreement.
          For the above purposes a change, event, condition or development shall
          be materially adverse in the above context if either alone or together
          with any other such change, event, condition or development it has led
          or is reasonably expected to lead over a period of two years from the
          date the notice under this Clause 7.5.1 is delivered to a reduction in
          the Net Asset Value of the Operations taken as a whole of USD110
          million (being approximately 20 per cent of the Net Asset Value of the
          Operations as stated in the 30.09.2000 Financial Statements).

     7.8.2 If after the date of this Agreement and prior to Completion any
          Seller breaches the terms of paragraphs (i), (ii) or (iii) of Clause
          6.5.1 XL Insurance shall be entitled by notice to Winterthur delivered
          prior to Completion to terminate this Agreement.

     7.8.3 Any failure to exercise any right of termination under this Clause
          7.5 shall not constitute a waiver of or otherwise prejudice any other
          rights of the Purchaser or its successors in title hereunder or under
          Applicable Laws. Notwithstanding the above in the event that XL
          Insurance has exercised its right of termination under Clauses 7.5.1
          or 7.5.2 and such termination occurs as a result amongst other things
          of any breach of this Agreement by the Sellers and/or any breach of
          Warranty as given at the date of this Agreement and/or any breach of a
          Core Warranty as at Completion which breach of Core Warranty results
          from the act or default of any of the Sellers or Business Sellers or
          any Group Company then in addition to exercising its right of
          termination and being indemnified as provided in the next sentence of
          this Clause 7.5.3 the Purchaser shall be entitled to exercise any
          other right or remedy hereunder or under Applicable Laws. If the
          Purchaser terminates the Agreement pursuant to this Clause 7.5 then
          Winterthur shall indemnify the Purchaser against all its costs and
          expenses relating to the negotiation, preparation, execution or
          termination of this Agreement. Except as provided in this Clause 7.5.3
          in the event that XL Insurance exercises its right of termination
          under this Clause 7.5 Winterthur and its Associated Companies and all
          other persons referred to in this Clause 7.5 shall have no further
          liability to the Purchasers or any other person in respect of this
          Agreement.
                                      -41-

7.9  Specific Performance

     The parties agree that they shall proceed to Completion in the terms set
     out in this Agreement and they further agree that damages are not an
     adequate remedy for failure of either party to fulfil any of its
     obligations under this Agreement and that the parties shall be entitled to
     seek an injunction or injunctions to prevent or cure breaches of the
     provisions of this Agreement and to enforce specifically the terms and
     provisions of this Agreement (including, without limitation, such party's
     obligations prior to and at Completion , and including, to sell the
     Operations), this being in addition to any other remedy to which they may
     be entitled by law or equity, and any party sued for breach of this
     Agreement expressly waives any defence that a remedy in damages would be
     adequate.

7.10 Transfer Taxes

     7.7.1 To the extent that any stamp duty, transfer, notarial or registration
          taxes (not being VAT) are payable in respect of this Agreement or any
          Local Agreement or any document pursuant to which any estate or
          interest or title is transferred to or otherwise vested in XL
          Insurance or any other Purchaser, XL Insurance shall pay such taxes or
          procure that such taxes are paid provided that, to the extent that
          payment of such taxes can be lawfully deferred or avoided (or
          otherwise mitigated), Winterthur and the Sellers shall use all
          reasonable endeavours to co-operate with XL Insurance with a view to
          deferring or avoiding (or otherwise mitigating) such payment.

     7.7.2 Notwithstanding the above, clause 7 of the Service Level Agreement
          shall apply in accordance with its terms in relation to that agreement
          and the services provided thereunder.

7.11 Consolidated Tax Groups

     Subject to anything to the contrary in the Tax Matters Agreement:

     7.11.1 Wintherthur and XL Insurance agree that where a Group Company is a
          member of a group which makes a consolidated return for any Taxation
          purpose arrangements shall be made before Completion to terminate any
          existing arrangements between members of the Winterthur Group and that
          Group Company for sharing tax payments and tax refunds so that the
          Group Company shall not on or after the Completion Date be required to
          make any payment to or be entitled to receive any payment from a
          member of the Winterthur Group in respect of any period ended prior to
          Completion other than amounts which have been taken into account in
          computing the Completion Balance Sheet; and

     7.11.2 if it does not prove possible to terminate the existing arrangements
          on the above basis referred to in Clause 7.8.1 or doing so would have
          adverse Tax consequences in the relevant jurisdiction, Winterthur and
          XL Insurance shall agree appropriate arrangements which achieve the
          same economic result for XL Insurance Group.

8.   Warranties

     8.4  Incorporation of Schedule 7

          8.4.1 As at the date of this Agreement Winterthur and each Seller
               warrants to XL Insurance (for itself and as trustee for each
               Purchaser) in relation to the Operations including as applicable
               the Businesses and the Shares that each Warranty in Schedule 7 is
               true, accurate and not misleading subject to any matter which is
               fully, fairly and specifically disclosed in or pursuant to the
               Disclosure Letter or expressly provided for under the terms of
               this Agreement.

          8.4.2 Immediately before Completion Winterthur and each Seller is
               deemed to warrant to XL Insurance (for itself and as trustee for
               each Purchaser) in relation to the Operations including as
               appropriate the Businesses and the Shares sold by any Seller to
               any Purchaser at the Completion Date that each Core Warranty
               remains true, accurate and not misleading subject to any matter
               which is fully, fairly and specifically disclosed in or pursuant
               to the Disclosure Letter or expressly provided for under the
               terms of this Agreement. For this purpose only where there is an
               express or implied reference in a Core Warranty to the "date of
               this Agreement" or similar references that reference is to be
               construed as also a reference to the Completion Date. For the
               avoidance of doubt except as otherwise expressly agreed by the
               Purchaser in the event that any matter is disclosed after the
               date of this Agreement in relation to any of the Core Warranties
               as reaffirmed under this Clause 8.1.2 pursuant to Clause

                                      -42-

               6.1.10 or otherwise such disclosure shall not prejudice any right
               of XL Insurance or other Purchasers hereunder including without
               limitation to make a claim in respect of breach of Warranty under
               this Clause 8 or any right under Clause 7.5 or Clause 9.

          8.4.3 The Sellers acknowledge that XL Insurance and each other
               Purchaser has entered into this Agreement in reliance upon each
               Warranty which has also been given as a representation and with
               the intention of inducing such Purchaser to enter into this
               Agreement. Save as expressly otherwise provided each Warranty
               shall be separate and independent and shall not be limited by
               reference to any other paragraphs of the said Schedule 7.

          8.4.4 The Sellers shall not invoke knowledge of XL Insurance or any of
               the other Purchasers (actual, constructive or imputed) of a fact
               or circumstance which might make a Warranty untrue, inaccurate or
               misleading as a defence to a claim for breach of this Clause 8.

          8.4.5 Any statement qualified by the expression "so far as the Sellers
               are aware" or words to that effect shall be deemed to refer only
               to matters within the actual knowledge of those persons named
               and/or holding the positions listed in Part 2 of Schedule 3 in
               each case as to their actual knowledge of the area of their
               expertise indicated opposite their names after making due and
               careful enquiry.

          8.4.6 For the avoidance of doubt each of the Warranties which is given
               in relation to the Group Companies is also true, accurate and not
               misleading in relation to each of the relevant branches of such
               Group Companies.

          8.4.7 As at the date this Second Amended and Restated Amendment
               Agreement was signed (the "Amendment Date") Winterthur warrants
               to XL Insurance (for itself and as trustee for each purchaser)
               and in relation to each Core Warranty is deemed to warrant to XL
               Insurance (for itself and as trustee for each Purchaser) as at
               Completion that each Warranty in Schedule 7 hereof shall apply to
               the business of the Operations (which for the purposes of this
               clause has the same meaning as is set out in Clause 5.1.4(ii) in
               so far as it relates to Germany), owned as at the date of the
               Agreement by Winterthur International (Deutschland) AG but
               excluding any and all motor insurance business, and that each
               Warranty is true, accurate and not misleading with respect to
               such business and in relation to the Core Warranties that each
               Core Warranty remains true, accurate and not misleading with
               respect to such business as at Completion . For the purposes of
               this paragraph 8.1.7 and Clause 2.6 only: (xcvi) the definition
               of "Business Seller" or "Business Sellers" and "Seller" and
               "Sellers" in Schedule 7 or in the definition referred to
               expressly or implied in this Clause 8.1.7 shall include
               Winterthur International (Deutschland) AG;

               (xcvii) any reference to "Agreement" or "Agreements" and "Local
                    Agreement" or "Local Agreements" in Schedule 7 or in the
                    definitions referred to expressly or implied in this Clause
                    8.1.7 shall be deemed to be a reference to the agreement
                    between Winterthur International (Deutschland) AG and
                    Winterthur International Insurance Company Limited dated 11
                    April 2001 relating to the transfer referred to in Clause
                    5.1.4 (the "German Transfer Agreement");

               (xcviii) the definition of "Operations" or "Operation" and
                    "Business" or "Businesses" in Schedule 7 or in the
                    definitions referred to expressly or implied in this Clause
                    8.1.7 shall for the avoidance of doubt include all of the
                    business, in so far as it relates to Germany, owned as at
                    the date of the Agreement by Winterthur International
                    (Deutschland) AG but excluding any and all motor insurance
                    business;

               (xcix) where there is any express or implied reference in any
                    Warranty in Schedule 7 or in the definitions referred to
                    expressly or implied in this Clause 8.1.7 to the "date of
                    this Agreement" or "date hereof" or "currently" or
                    "presently" or similar references that reference is to be
                    construed as a reference to the Amendment Date;

               (ci) any reference to "since 30 September 2000" or to "since 31
                    December 1999" in Schedule 7 shall be deemed to be a
                    reference to since 31 December 2000;

                                      -43-

               (cii) any reference to "Schedule 11" in Schedule 7 or in the
                    definitions referred to expressly or implied in this Clause
                    8.1.7 shall be deemed to be a reference to "Schedule 11 and
                    Schedule 15" (and Winterthur hereby warrants the accuracy of
                    such Schedule 15); and

               (ciii) any reference to "Relevant Employees" or "Business
                    Employees" shall include directors, agents or any other
                    person performing a role equivalent to that of an employee.

          8.4.8 As at the Completion Date Winterthur warrants to XL Insurance
               (for itself and as trustee for each Purchaser) that the transfer
               referred to in Clause 5.1.4(ii) has been completed and that the
               agreement dated 11 April 2001 between the parties thereto
               operates to transfer the Operations, other than the Excluded
               Operations, as referred to in Clause 5.1.4(ii).

          8.4.9 As at the Completion Date Winterthur Warrants to XL Insurance
               (for itself and as trustee for each Purchaser) that Schedule 16
               is an accurate summary of the reinsurance of the Operations by
               Winterthur International (Re) in Hungary, Czech Republic, Poland,
               Singapore and Japan.

8.5  Limitation of Liability Notwithstanding the provisions of Clause 8.1:

     8.5.1 Time Limits

          (civ) The Sellers shall not be liable in respect of any Specified
               Claim unless notice of such Specified Claim is given in writing
               by XL Insurance to Winterthur on behalf of the Sellers (setting
               out reasonably comprehensive details in respect of which the
               Specified Claim is made including an estimate of the amount of
               such Specified Claim if practicable) on or before 30 April 2003
               except that the limit shall be six years and one month from the
               end of the accounting period of the relevant Group Company
               current at Completion in the case of any Specified Claims
               relating to Taxation in the United Kingdom or one month after the
               expiry of the relevant local statutory limitation period after
               which the relevant Tax authority cannot bring a claim or make an
               assessment in relation to Specified Claims relating to Taxation
               in any jurisdiction other than the United Kingdom or where there
               is no such period six years from Completion , provided that the
               limitations set out in this Clause 8.2.1(i) shall not apply to
               Warranties in paragraphs 3 (The Shares) or 12.1 (Ownership of the
               Subsidiaries) of Schedule 7.

          (cv) Any such Specified Claim (other than a Specified Claim under
               paragraph 11 (Tax) of Schedule 7) or under the Tax Matters
               Agreement) shall (if it has not been previously satisfied,
               settled or withdrawn) be deemed to be withdrawn nine months after
               the relevant time limit set out above unless legal proceedings in
               respect of it have been commenced by being both issued and served
               provided that:

               (c)  in respect of claims in respect of Losses which remain
                    contingent the relevant time limit will if later be nine
                    months after such contingency crystallises; and

               (d)  where due to lack of information it is not practicable for
                    XL Insurance properly to pursue a litigated claim the
                    relevant time limit shall if later be nine months after it
                    does so become practicable.

     8.5.2 Minimum Claims

          The Sellers shall not be liable in respect of any Specified Claim
          (other than a Specified Claim under paragraphs 3 (The Shares) or 12.1
          (Ownership of the Subsidiaries) of Schedule 7) arising from any single
          circumstance if the amount of such Specified Claim does not exceed
          USD100,000 (and claims relating to connected matters shall be treated
          as arising from a single circumstance and aggregated for this purpose)
          but the Sellers shall not be liable for a Specified Claim in excess of
          that amount unless the liability determined in respect of any such
          Specified Claim (excluding interest, costs and expenses) also exceeds
          that amount. For the avoidance of doubt the Seller shall subject to
          the terms of Clause 8.2.3 be liable for the whole of any such claim
          and not merely the excess over USD100,000.

                                      -44-

     8.5.3 Aggregate Minimum Claims The Sellers shall not be liable in respect
          of any Specified Claim (other than a Specified Claim under paragraphs
          3 (The Shares) or 12.1 (Ownership of the Subsidiaries) of Schedule 7)
          unless and to the extent that the aggregate amount of all Specified
          Claims for which the Sellers would otherwise be liable under this
          Agreement exceeds USD8 million in which case the Sellers shall be
          liable for the whole of such claims and not merely the excess over
          USD8 million.

     8.5.4 Maximum Claims The Sellers shall not be liable in respect of any
          Specified Claim to the extent that the aggregate amount of the
          liability of the Sellers would exceed:

          (cvi) the aggregate amount of the Purchase Price in the case of any
               Specified Claim under any Core Warranty; or

          (cvii) 60 per cent of the aggregate amount of the Purchase Price in
               all other cases,

          provided that for the avoidance of doubt in no circumstances shall
          such aggregate liability of the Sellers exceed the aggregate amount of
          the Purchase Price.

     8.5.5 Specified Indemnities, Fraud and Dishonesty Notwithstanding the
          above, the restrictions and limitations set out in Clauses 8.2.1 to
          8.2.4 or elsewhere in the Agreement shall not apply:

          (cviii) to Clause 9.1; or

          (cix) to the extent that the matter giving rise to a Specified Claim
               is a result of any fraud, dishonesty or wilful misconduct, wilful
               concealment or wilful default on the part of any Seller.

     8.5.6 Contingent Liabilities The Sellers shall not be liable in respect of
          any Specified Claim where a liability is contingent unless and until
          such contingent liability becomes an actual liability and is due and
          payable but this Clause 8.2.6 shall not operate to avoid a Specified
          Claim made in respect of a contingent liability within the applicable
          time limit specified in Clause 8.2.1 if the requisite details of such
          claim, such as they are known by the Purchaser have been delivered
          before expiry of such period (even if such liability does not become
          an actual liability until after the expiry of the relevant period).

     8.5.7 Provisions in the Completion Balance Sheet The Sellers shall not be
          liable in respect of any Specified Claim if and to the extent that
          provision or reserve is made for the matter giving rise to the claim
          in the Completion Balance Sheet or such matter is written off as
          irrecoverable in the Completion Balance Sheet or is otherwise
          specifically taken into account in calculating the Purchase Price
          (including as a result of Clause 3.6).

     8.5.8 Events Beyond the Control of the Sellers The Sellers shall not be
          liable in respect of any Specified Claim to the extent that such
          Specified Claim would not have occurred but for:

          (a)  the passing of or any change after Completion in any law, rule,
               or regulation including without limitation to the generality of
               the foregoing any increase in the rates of Taxation or any
               imposition of Taxation or any withdrawal of relief from Taxation
               not actually in effect at the date of this Agreement; or

          (b)  any change in accounting policy, bases or practice of XL
               Insurance or any member of XL Insurance Group or any Group
               Company introduced or having effect after Completion other than

     8.5.9 Insurance

          The Sellers shall not be liable in respect of any Specified Claim to
          the extent that any liability arising from such Specified Claim is
          recovered by the XL Insurance Group after Completion under a policy of
          insurance in force immediately prior to Completion.

8.6  Mitigation of Loss

     XL Insurance shall procure that all reasonable steps are taken and all
     reasonable assistance is given to avoid or mitigate any Losses which in the
     absence of mitigation might give rise to a liability on the part of the
     Sellers in respect of any Specified Claim provided always that:

     8.6.1 the Purchasers shall not be required hereunder to exercise any right
          or remedy hereunder or make any claim which they may have in respect
          of any misrepresentation in or omission from any information or advice
          supplied or given by any Group Company or Relevant Employee;

     8.6.2 for the avoidance of doubt the Purchasers shall not hereby be
          precluded from making any claim against any Seller; and

     8.6.3 the Purchasers shall be entitled to receive all reasonable assistance
          and co-operation from the Sellers in relation to its obligations
          hereunder.

8.7  Conduct of Claims

     Save in respect of a Specified Claim relating to Taxation (to which the
     provisions of the Tax Deed shall apply) or in respect of any claim, payment
     or adjustment to be made pursuant to Clause 4 or Schedule 5 or in respect
     of Specified Claims under Clause 9.1.7 which relate to claims under or in
     connection with insurance or reinsurance policies issued by the Operations:

     8.7.1 If any party to this Agreement (the "Claimant") becomes aware of any
          matter that is likely in the reasonable opinion of the Claimant to
          give rise to a Specified Claim against another party to this Agreement
          (the "Recipient") under this Agreement notice of that fact shall be
          given to the Recipient as soon as and in any case within seven
          Business Days thereafter but failure to give such timely notice shall
          not affect the rights of the Claimant except to the extent that the
          Recipient is prejudiced by such failure.

     8.7.2 Without prejudice to the validity of the claim or alleged claim in
          question the Claimant shall on reasonable terms allow and shall
          procure that the relevant Associated Companies of the Claimant allow
          the Recipient and its accountants and professional advisers to
          investigate the matter or circumstance alleged to give rise to such
          claim and whether and to what extent any amount is payable in respect
          of such claim and for such purpose the Claimant shall give and shall
          procure that the relevant Associated Companies of the Claimant give
          subject to the Recipient providing an indemnity in terms reasonably
          satisfactory to the Claimant in respect of all reasonable
          out-of-pocket costs and expenses, all such reasonable information and
          assistance including access to premises and personnel and the right to
          examine and copy or photograph any assets, accounts, documents and
          records as the Recipient or its accountants or professional advisers
          may reasonably request provided that subject to Clause 8.4.3(iii) the
          Claimant shall not be required to provide access to or copies of any
          information which is of a legally privileged nature.

     8.7.3 If the Specified Claim in question is a result of or in connection
          with a claim by or liability to a third party then:

          (cx) no admission of liability shall be made by or on behalf of the
               Claimant or any Associated Company of the Claimant and the claim
               shall not be compromised, disposed of or settled within 30
               Business Days of the relevant notice served pursuant to Clause
               8.4.1 (the "Recipient's Assessment Period") without the consent
               of the Recipient such consent not to be unreasonably withheld or
               delayed;

          (cxi) the Claimant shall keep the Recipient informed of the progress
               of the relevant claim including by way of the provision of all
               such documentation as may be reasonably necessary or desirable as
               often as is reasonable and in any event at no less than monthly
               intervals after giving notice of the matter pursuant to Clause
               8.4.1 provided that the Recipient shall treat and shall procure
               that its professional advisers shall treat all information and
               documents which it has been provided with as

                                      -46-

               confidential and shall not disclose such information and document
               to any third party (other than professional advisers) and shall
               use it only for the purpose of dealing with the relevant claim
               (unless the Recipient has obtained the prior written consent of
               the Claimant or the information was already known to the
               Recipient or the information comes into the public domain
               otherwise than a breach by the Recipient) and provided that
               nothing in this Clause 8.4.3 shall (unless the Claimant has taken
               control of the litigation following an appropriate indemnity in
               accordance with Clause 8.4.3(iii)) require the Claimant to
               provide the Recipient with a copy of any document which it in
               good faith considers and acting reasonably believes to be
               privileged as against the Recipient in the context of any actual
               or threatened litigation connected with the Specified Claim in
               which case the Claimant shall promptly notify the Recipient of
               that fact and as much other information about the document as can
               be disclosed to the Recipient without losing that privilege; and

          (cxii) (subject to the Claimant being indemnified to its reasonable
               satisfaction by the Recipient for any reasonably incurred costs,
               charges, losses, expenses and other liabilities incurred by it as
               a result of taking such action and the Claimant being reasonably
               satisfied that such action would not otherwise have an unduly
               adverse effect on the Operations) the Claimant shall (provided
               that the Recipient shall have notified the Claimant that it
               wishes to control such action within 10 Business Days of the
               relevant notice served pursuant to Clause 8.4.1 or such later
               date as the parties may expressly agree) take all such action as
               the Recipient may reasonably request, including the institution
               of proceedings and the instruction of professional advisers
               nominated by the Recipient to act on behalf of the Claimant to
               avoid, dispute, resist, compromise, defend or appeal against any
               such claim against the Claimant, or to make such recovery by the
               Claimant, as the case may be, in accordance with the reasonable
               instructions of the Recipient. The Recipient shall ensure that
               the Claimant is kept fully informed of the progress of any such
               action.

                                      -47-

     8.7.4 XL Insurance agrees that after the Completion Date XL Insurance shall
          or shall procure that another Purchaser or a Group Company shall
          retain and exert reasonable efforts to preserve the condition of the
          relevant Books and Records and the books and records of the Group
          Companies. The Sellers will use reasonable efforts to preserve the
          condition of all books and records of or relating to the Sellers and
          the Businesses which are or may be relevant in connection with any
          claim brought by XL Insurance or any Purchaser against the Sellers
          under this Agreement or the operations of the Businesses by the
          Purchaser after Completion for a seven year period or if longer for so
          long as any actual or anticipated claims remain outstanding.

     8.7.5 XL Insurance agrees that if Winterthur or any member of Winterthur
          Group is in receipt of a claim in relation to a Liability other than
          an Assumed Liability the provisions of Clauses 8.4.2 to 8.4.4 shall at
          the request of Winterthur apply mutatis mutandis to such claim as if
          references to the Recipient were to Winterthur or the relevant member
          of Winterthur Group and references to the Claimant were to XL
          Insurance or the relevant Purchaser or Group Company.

     8.7.6 Winterthur agrees that if XL Insurance or any member of XL
          Insurance's Group is in receipt of a claim in relation to an Assumed
          Liability the provisions of Clauses 8.4.2 to 8.4.4 shall at the
          request of XL Insurance apply mutatis mutandis to such claim as if
          references to the Recipient were to XL Insurance or the relevant
          member of XL Insurance's Group and references to the Claimant were to
          Winterthur or the relevant member of Winterthur Group.

8.8  Third Party Claims and Prior Receipt

     8.8.1 Where XL Insurance or any Purchaser or any Group Company is entitled
          as a matter of law or pursuant to any contractual arrangement of the
          Group Companies existing prior to Completion to recover (due to
          circumstances or arrangements of any of the Group Companies existing
          prior to Completion) from some other person Losses which could give
          rise to a claim against the Sellers for breach of Warranty the person
          so entitled shall not be obliged to pursue such claim against such
          third party before pursuing a claim against the Sellers provided that
          this Clause 8.5.1 shall not negate the Purchasers' duty to mitigate
          under Clause 8.3.

     8.8.2 If any party pays an amount in discharge of any Specified Claim under
          this Agreement and the other party subsequently recovers (whether by
          payment, discount, credit, relief or otherwise) from a third party a
          sum which is referable to the subject matter of the claim and which
          would not before the matter giving rise to the Specified Claim have
          been received by such other party that party shall pay on behalf of
          itself or the relevant Purchasers or Sellers as the case may be to the
          other party an amount equal to: (cxiii) the sum recovered from the
          third party minus any out of pocket costs and expenses reasonably
          incurred in obtaining such recovery and minus also any Taxation costs,
          charges or other deductions chargeable or suffered in respect of such
          sum; or

          (cxiv) if less the amount previously paid by the party to the other
               party.

8.9  Double Claims

     8.6.1 XL Insurance and any Purchasers taken together shall not be entitled
          to recover from the Sellers under this Agreement or any Local
          Agreement or the Tax Deed or the Sellers' Retrocession Agreement or
          otherwise in connection with the subject matter of this Agreement more
          than once in respect of the same Losses and accordingly the Sellers
          shall not be liable in respect of any Specified Claim under any one
          such document if and to the extent that the Losses have been paid in a
          claim under another such agreement. Without limitation to the
          generality of the foregoing to the extent that any Losses have been
          recovered in full by the Purchaser through the Net Asset Value
          calculation or the provisions of Clause 4 the Seller shall not be
          liable to the Purchaser for the same Losses under any other provision
          of this Agreement or any Local Agreement or the Tax Deed or the
          Sellers Retrocession Agreement or otherwise in connection with the
          subject matter of this Agreement.

     8.6.2 The parties acknowledge that the purchase price adjustment, the
          Sellers Retrocession Agreement and the seasoning of reserves under
          this Agreement interact. The double claims

                                      -48-

          provision in this Clause 8.6 should be interpreted so that the net
          economic effect (ignoring the time value of money) of the above
          referenced agreements should be the same as if the Sellers
          Retrocession Agreement did not exist.

8.10 Effect of Completion

     The Warranties and all other provisions of this Agreement and each Local
     Agreement in so far as the same shall not have been performed at Completion
     shall not be extinguished or affected by Completion or by any other event
     or matter whatsoever (including without limitation any satisfaction and/or
     waiver of any condition contained in Clause 5.1) except by a specific and
     duly authorised written waiver or release by XL Insurance.

8.11 Information Supplied to the Sellers

     Winterthur agrees with XL Insurance for itself and as trustee for each
     Purchaser and each relevant Group Company and each Relevant Employee to
     assign and to procure that any other relevant member of the Winterthur
     Group assigns to XL Insurance, any rights, remedies or claims which any of
     them may have in respect of any misrepresentation in or omission from any
     information or advice supplied or given by any Relevant Employee and on
     which the Sellers have relied in giving the Warranties, preparing the
     Disclosure Letter or entering into this Agreement or any Local Agreement
     other than to the extent that that Relevant Employee has acted with fraud,
     dishonesty or wilful misconduct, wilful concealment or wilful default.

8.12 Remedial Action

     If a breach of any of the Warranties occurs prior to Completion then
     without prejudice to the right of XL Insurance to claim damages to the
     extent that a breach of any of the Warranties is capable of being remedied
     the Sellers shall be afforded a reasonable opportunity to remedy the matter
     the subject of the breach which remedy may include the payment by
     Winterthur on behalf of the Sellers to XL Insurance or another Purchaser of
     such compensation as shall place XL Insurance or such other relevant
     Purchaser (after taking account of any taxation to which such compensation
     may be subject) in an equivalent position to that in which it would have
     been had such breach of Warranty not occurred.

8.13 Warranties from XL Insurance

     XL Insurance and each relevant Purchaser warrants to each of the Sellers in
     the terms set out in Schedule 13 subject only to any exception fairly
     disclosed to Winterthur on or prior to the date of this Agreement.

8.14 Entire Agreement

          induced to enter this Agreement by and (so far as is permitted by law
          and except in the case of fraud) hereby waives any remedy in respect
          of any warranties, representations and undertakings not incorporated
          into this Agreement.

     8.14.2 Each party to this Agreement confirms it has received independent
          legal advice relating to all the matters provided for in this

          having considered the terms of this Clause 8.11 and this Agreement as
          a whole that the provisions of this Clause 8.11 are fair and

     8.15.1 The remedies available to the parties for breach of any of the
          provisions of this Agreement consist of any one or any combination

                                      -49-

          Agreement) of the following subject where relevant to the limitations
          on liability expressly set out in this Clause 8: (cxv) the right to
          terminate the Agreement in the circumstances and in the manner set out
          in Clause 7.5;

          (cxvi) the equitable remedies of injunction, rectification, or

               7.6);

          (cxvii) the right to seek damages in tort for negligent mis-statement,

          or partial exercise of a right or remedy provided by this Agreement or
          by law prevents further exercise of the right or remedy or the

          in this Agreement, to the extent permitted by law all rights and

     Business or Operations which arise directly or indirectly out of or in
     connection therewith (including without limitation each Loss incurred as
     result of defending or settling a claim alleging such liability).
     Notwithstanding the above neither Winterthur nor any of the other Sellers
     shall be liable for any such Loss:

     9.5.1 to the extent that the relevant matter is accounted for in the
          mechanism for adjusting the Purchase Price contained in Clauses 3.1 or
          3.6; or

     9.5.2 if the parties agree another adjustment to the Purchase Price to take
          account of such matter.

9.6  Property Indemnity

     9.6.1 Winterthur shall and shall procure that the Sellers shall indemnify

          Parties") against any Losses incurred or suffered by any relevant
          Indemnified Party (as the case may be) in relation to any matter,
          state of affairs or circumstances which exist prior to or on the date
          on which the legal and beneficial title in the

                                      -53-

          Property vests in the relevant Indemnified Party ("Property
          Completion") and affect the Properties (each such instance of Loss
          being referred to as a "Property Claim") other than: (cxxi) any such
          matter, state of affairs or circumstances which arises directly and
          solely as a result of a change in market value of any property brought
          about by economic, financial, regulatory or political conditions or
          the state of the property market generally but this shall not apply
          where the change in market value has been brought about solely by a
          direct act or omission of Winterthur or its Associated Companies; and

          (cxxii) any such matter which is shown in the Completion Balance
               Sheet.

     9.6.2 Minimum Claims

          Property Claim arising from any single circumstance if the amount of
          such Property Claim does not exceed USD100,000 (and claims relating to
          connected matters shall be treated as arising from a single
          circumstance and aggregated for this purpose) provided that the
          Indemnifying Parties shall not be liable for a Property Claim in
          excess of that amount unless the liability determined in respect of
          any such Property Claim (excluding interest, costs and expenses) also
          exceeds that amount. For the avoidance of doubt the Indemnifying
          Parties shall subject to the terms of Clause 9.3.3 be liable for the
          whole of any such claim and not merely the excess over USD100,000.

     9.6.3 Aggregate Minimum Property Claims

          The Indemnifying Parties shall not be liable in respect of any
          Property Claim unless and to the extent that the aggregate amount of
          all Property Claims for which the Indemnifying Parties would otherwise
          be liable under this Agreement exceeds USD5 million in which case the
          Indemnifying Parties shall not be liable for the whole of such claims
          but merely the excess over USD5 million.

     9.6.4 Incorporation of Clause 8

          The following clauses shall apply where applicable mutatis mutandis to
          each Property Claim under Clause 9.3.1 as if references to "Specified

          "Indemnifying Parties" and "XL Insurance", "XL Insurance Group",

          "Indemnified Parties" and "Completion" were to "Property Completion":

          the occupation and use of the Property and/or Additional Property
          pursuant to the provisions of Schedule 10 then, if not in place at
          Completion the indemnity contained in Clause 9.3.1 shall continue
          after Completion to relate to any matter, state of affairs or
          circumstances in existence until the date when such document has been
          completed.

     9.6.6 Additional Properties

          In relation to the Additional Properties the Indemnifying Parties
          shall indemnify the relevant Indemnified Party against any Losses
          incurred or suffered by the relevant Indemnified Party in relation to
          any matter, state of affairs or circumstances which exists prior to or
          at the date on which the legal and beneficial title in the Additional
          Property vests in the relevant Indemnified Party as at the date on
          which the legal and beneficial title in the Additional Property vests
          in the relevant Indemnified Party and affecting the Additional
          Properties other than any such matter, state of affairs or
          circumstances which arise directly and solely as a result of a change
          in market value of any Additional Property brought about by economic,
          financial, regulatory or political conditions or the state of the
          property market generally but this shall not apply where brought about
          solely by a direct act or omission of Winterthur or its Associated
          Companies.

     9.6.7 Winterthur shall and shall procure that the Sellers shall indemnify
          the Indemnified Parties (as defined in Clause 9.3.1) against any
          Losses incurred or suffered by any relevant Indemnified Party arising
          as a result of any action taken by any landlord under any Leasehold
          Agreement terminating any Leasehold Agreement as a result of the
          occupation of any Leasehold Property by any Purchaser where such
          occupation arose as a result of any licence contemplated by Clause
          2.1.15 of this Agreement unless such action is caused by the
          Purchaser's non-compliance with the terms of the Leasehold Agreements
          or any matter affecting the reversionary interest to any Leasehold
          Property or the breach or non-compliance by any Purchaser of any
          Applicable Laws or legal code.

     9.6.8 The Purchaser shall indemnify Winterthur against any Losses incurred
          or suffered by Winterthur or any Seller as a result of any Purchaser's
          non-compliance with the terms of any Leasehold Agreement or Licence to
          Occupy or any matter affecting the reversionary interest to any
          Leasehold Property or the breach or non-compliance by any Purchaser of
          any Applicable Laws or legal code excluding any Losses arising merely
          by virtue of the Purchaser's occupation or possession of any Leasehold
          Property.

     9.6.9 From the Completion Date Winterthur shall indemnify XL Insurance
          against any Losses incurred or suffered by XL Insurance or any

          any Leasehold Agreement or Licence to Occupy or any matter affecting
          the reversionary interest to any Leasehold Property or the breach or
          non-compliance by any Seller of any Applicable Laws or legal code.

     against any liability which may be incurred by each relevant Purchaser in

     which may arise in respect of any award or benefit made to Relevant

     Subject to Clause 10.2 if and to the extent that any Business Seller has
     prior to Completion made any payment in respect of any Contract or
     Retrocession Contract which payment relates solely to a period after the
     Effective Time or any Purchaser has after the Effective Time received any
     payment in respect of any Contract which payment relates solely to a period
     prior to the Effective Time XL Insurance shall or shall procure that other
     Purchasers as appropriate shall unless the same has been taken into account

     Contract or Retrocession Contract which payment relates solely to a period
     before the Effective Time or any Business Seller receives a payment in
     respect of any Contract which payment relates solely to a period after such
     Effective Time or any Business Seller receives any payment in respect of
     any Policy or Retrocession Contract which has been transferred to a

     obtain credit or repayment of input tax for VAT purposes in respect of
     supplies of goods and/or services (made under a Contract, Retrocession
     Contract or Policy) to which such amounts relate and the liability of XL
     Insurance or Winterthur as applicable under Clause 10.1 shall be reduced
     accordingly.

11.  Third Party Consents

11.4 Consents

     Nothing in this Agreement shall be construed as an attempt to assign any
     Business Asset (including any Contract, Retrocession Contract or Policy)
     which by its terms or by law is not assignable without a Third Party
     Consent unless such consent shall have been given.

11.5 Failure to Obtain Consents

     11.5.1 If any Business Asset cannot be vested in XL Insurance except by way
          of conveyance, novation, transfer or assignment in each case requiring
          a Third Party Consent then where the relevant Third Party Consent has
          not been obtained on or prior to Completion in respect of any such
          Business Asset such Business Asset shall not be conveyed, transferred
          or assigned by this Agreement or any local Agreement or otherwise on
          Completion but: (a) shall (except in the case of Policies and
          Retrocession Contracts to which the provisions of paragraph 2.2 of
          Part 1 of Schedule 2 shall apply) be held in trust for XL Insurance
          absolutely from Completion until the relevant Third Party Consent is
          obtained and the relevant Business Asset is so conveyed, transferred
          or assigned. Until such conveyance, transfer or assignment or until
          the license with respect to the relevant Business Asset is terminated
          pursuant to the provisions of Clause 2.1.17 XL Insurance shall (to the
          extent that it may lawfully do so) perform all the obligations of the
          relevant Business Seller thereunder and shall indemnify the Business
          Seller against all Losses incurred by the Business Seller by reason of
          or in connection with the non-performance or the negligent or
          defective performance by XL Insurance or any Purchaser of such
          obligations (except to the extent that such obligations have not been
          performed as a result of a failure by any Seller to follow the
          directions of the relevant Purchaser) and the Business Seller shall
          otherwise co-operate in any reasonable arrangements proposed by XL
          Insurance designed to procure for XL Insurance the benefits of the
          relevant Business Asset. If in the case of any Contract any such Third
          Party Consent is not obtained within six months after Completion (or
          any reasonable longer period as Winterthur and XL Insurance may agree)
          Winterthur shall procure that the relevant Business Seller shall if XL
          Insurance reasonably requests in writing and subject to XL Insurance
          providing an indemnity in terms reasonably satisfactory to the
          relevant Business Seller in respect of all reasonable out of pocket
          costs and expenses and subject further to such Business Seller being
          indemnified for any Losses (including any Taxation) it may incur in
          connection therewith use reasonable endeavours to procure the lawful
          termination of the relevant Contract, any Losses being incurred on
          termination being for the account of XL Insurance or the relevant
          Purchaser;

          (b)  Winterthur shall procure that the relevant Business Seller shall
               at its cost make or assist XL Insurance in making application for
               any such Third Party Consent and together with XL Insurance
               endeavour to obtain such conveyance, transfer or assignment as
               aforesaid such that the relevant conveyance, transfer or
               assignment is effective from Completion . XL Insurance shall
               supply to Winterthur such information and references regarding
               the financial position of XL Insurance as may reasonably be
               requested by Winterthur and shall enter into such direct
               covenants in favour of any relevant third party as may reasonably
               be requested in respect of any rent charges, rents, royalties,
               fees or other outgoings or liabilities for which XL Insurance or
               any Purchaser will from Completion become liable. If required by
               any third party XL Insurance shall give such reasonable
               additional covenants requested by any third party as a condition
               of giving their consent (provided that such covenants shall be no
               more extensive than those

                                      -56-

               given by the relevant Business Seller) and shall generally use
               reasonable endeavours to secure such consent; and

          (c)  when and until any relevant Business Assets are conveyed,
               transferred or assigned Winterthur shall (so far as it lawfully
               may) and shall procure that the relevant Business Seller shall
               give reasonable assistance to XL Insurance to enable XL Insurance
               to enforce its rights in relation to the Business Asset.

          References to XL Insurance in this Clause 11.2 shall be deemed to
          include references to each Purchaser.


11.6 Right of Exclusion

     In any case where the relevant Third Party Consents are not obtained within
     12 months after the Completion Date the relevant Business Seller, by notice
     to XL Insurance or the relevant Purchaser, by notice to Winterthur, shall
     be entitled to exclude the relevant Business Assets concerned or any of
     them from the sale under this Agreement and references in this Agreement to
     the Business Assets (or any assets comprised therein), the Properties and
     the Businesses (other than in this Clause 11.3) shall thereafter be
     construed as excluding the Business Asset concerned and the amount of the
     Purchase Price referable to that Business Asset shall be refunded without
     interest.

11.7 Purchasers' rights not affected

     Nothing in this Clause 11 affects the Purchasers' rights and remedies

     15.4.1 If any Business Seller becomes aware after Completion of any claim
          of which it believes that XL Insurance is not aware which constitutes
          or may constitute an Assumed Liability the relevant Business Seller
          shall as soon as reasonably practicable give written notice thereof to
          XL Insurance and shall not admit, compromise, settle, discharge or
          otherwise deal with such claim without prior consultation with and the
          prior agreement of XL Insurance.

     15.4.2 The relevant Business Seller shall take such action as XL Insurance
          may reasonably request to avoid, dispute, resist, appeal, compromise,
          defend or mitigate any claim which constitutes or may constitute an
          Assumed Liability but subject to the relevant Business Seller (and if
          Winterthur reasonably requests other members of Winterthur Group)
          being indemnified and secured to its reasonable satisfaction by XL
          Insurance against all Losses which may thereby be incurred. In
          connection therewith the relevant Business Seller shall and (if such
          Business Seller is not Winterthur) Winterthur shall procure that it
          shall make or procure to be made available to XL Insurance or its duly
          authorised agents on reasonable notice during normal business hours
          all relevant books of account, records and correspondence relating to
          the Operations which have been retained by the relevant Business
          Seller (and shall permit XL Insurance to take copies thereof) for the
          purpose of enabling XL Insurance to ascertain or extract any
          information relevant to the claim except to the extent that such
          information is the subject of legal privilege.

          Sellers in relation to any debt or obligation of any Group Company
          which are referred to in the Disclosure Letter and such others as the
          parties may agree prior to Completion . Pending such release XL
          Insurance shall indemnify and keep indemnified the Sellers from and

          with such securities, guarantees and indemnities and any other
          securities, guarantees and indemnities binding upon any of the Sellers
          in relation to any debt or obligation of any Group Company to the
          extent that such obligations are otherwise Assumed Liabilities or
          otherwise obligations of the Group Companies (subject to XL
          Insurance's right to control any Claim thereunder).

     15.5.2 Save as set out below at Completion the Sellers shall procure the
          release of all security, guarantees and indemnities (for the avoidance
          of doubt not including indemnities under those insurance or
          re-insurance contracts which the parties have agreed will remain in
          place after Completion) given by or binding on any Group Company in
          relation to any debt or obligation of any of the Sellers or other
          persons as aforesaid. Pending such release the Sellers shall indemnify
          and keep indemnified XL Insurance as trustee for itself and the Group
          Companies concerned from and against all costs, claims and demands
          arising out of or in connection with any such securities, guarantees
          and indemnities.

          that:

          (a)  Winterthur International shall continue to have access to the
               Winterthur cash pool facility for a period of two years following
               Completion on the terms set out in the Limited Recourse
               Receivables Financing Facility Agreement;

          (b)  any letters of credit given or supported by members of the CS
               Group in relation to the Operations shall remain in place
               notwithstanding Completion for so long as the Purchaser requires
               up to 1 July 2002 on the terms set out in the LOC Facility
               Agreement; and

          (c)  XL Insurance and Winterthur will co-ordinate with each other with
               respect to any replacement or termination of any "comfort"
               letters provided by or on behalf of Winterthur to customers or
               clients of the Operations so as to minimise any disruption of the
               relevant Operations.

     pay to XL Insurance as soon as reasonably practicable and in any event
     within five Business Days of receipt thereof the amount recovered minus any
     cost of recovery and minus any Taxation payable by Winterthur or the
     relevant Business Seller which would not have arisen but for the receipt of

     to account to a Taxation authority for such VAT.

15.7 Sellers' Continuing Obligations

     Notwithstanding Completion the Sellers shall at their own expense:

     15.7.1 procure that if any property, rights or assets forming part of the
          Operations which ought to have been transferred or licensed to any
          Purchaser (other than any property, rights or assets expressly
          excluded from the sale under this Agreement or any Local Agreement)
          and which are capable of being so transferred or licensed are not
          transferred or licensed by a Seller at Completion the relevant Seller
          transfers or licenses such property, rights or assets to XL Insurance
          or any other relevant Purchaser as soon as practicable after it is
          discovered that such property, rights or assets should have been
          transferred or licensed to XL Insurance or any other relevant
          Purchaser at Completion and without limitation to the generality of
          Clause 18.4.2 to the extent that such property, right or asset

          for any purpose at any time (including but not limited to after it is
          transferred or licensed to XL Insurance). If any such property, rights
          or assets are not included in the calculation of the Purchase Price
          Winterthur and XL Insurance shall agree the amount of consideration to
          be paid by XL Insurance in respect of such property, rights or assets
          failing which the Reporting Accountants shall determine the amount of
          such consideration;

          suppliers, their current contracts and engagements and their trade
          debtors and trade creditors and pass on any trade enquiry which the
          Sellers receive provided that nothing in this Clause 15.4.2 shall
          require the Sellers to do anything which may breach any Applicable
          Laws or regulation including without limitation to the generality of
          the foregoing the Data Protection Act 1998;

     15.7.3 without prejudice to the provisions of Clause 11 from time to time
          execute and perform all such acts, deeds and documents and afford to
          XL Insurance or any other relevant Purchaser such assistance as XL
          Insurance may reasonably require including commencing or defending any
          litigation: (a) for the purpose of vesting in XL Insurance or the

          and the Shares and implementing all the relevant provisions of this
          Agreement;

          (b)  for the purpose of vesting in XL Insurance or the relevant
               Purchaser the full benefit of any rights, powers, remedies,

               and counterclaim which any of the Business Sellers may have in
               relation to any Claim or Assumed Liability or otherwise ensuring
               that the same ensure for the benefit of XL Insurance or the
               relevant Purchaser;

          (c)  to enable any claim, action, suit, prosecution, litigation,
               proceedings, dispute or arbitration to which any of the Business
               Sellers was a party and which relates to any Claim or Assumed
               Liability to be continued by or against XL Insurance or the
               relevant Purchaser; and

          (d)  to enable any judgment or award obtained by any of the Business
               Sellers and not fully satisfied as at Completion to the extent to
               which it is a Claim enforceable by the relevant Business Sellers
               to be enforced by XL Insurance or the relevant Purchaser whether
               by XL Insurance or the relevant Purchaser joining itself as a
               defendant or by

                                      -59-


               XL Insurance or the relevant Purchaser consenting to any

     15.7.6 procure (subject to the relevant member of the XL Insurance Group
          executing an appropriate transfer agreement on terms reasonably
          satisfactory to it and otherwise complying with Clause 18.16) that any
          Excluded Operations not transferred to a member of the Winterthur

          practicable after Completion and in any event within 6 months of
          Completion ;

          Company at Completion all steps required to be taken by the relevant

          promptly after XL Insurance serves notice requiring such transfer as
          provided in Schedule 2, Part 1;

     15.7.8 cause each Business Seller that retains a Portfolio after Completion

          similar rights provided to XL Insurance or the Operations under the
          Local Agreements and the other agreements referred to in Schedule 2;

          a statement of net assets, income statements and statement of cash
          flows and related summary footnotes), for the six month period ending
          30 June 2001 together with a letter from Winterthur's Accountants that
          they have performed the procedures specified by the American Institute
          of Certified Public Accountants for a review of interim financial
          information as described in SAS No. 71, Interim Financial Information.
          Winterthur and XL Insurance will cooperate with one another in the

          trade marks shall be removed from all business stationery, all other

          Completion Date. The Business Sellers shall execute and deliver such
          other instruments of transfer, conveyance, and assignment as XL

          Completion no member of Winterthur Group shall have any obligation to
          maintain or prosecute any of the Business Intellectual Property.
          However if any member of Winterthur Group is involved in the

          Property XL Insurance shall reimburse such member for all fees
          incurred in the maintenance or prosecution of such Business
          Intellectual Property including but not limited to maintenance fees,
          renewal fees and agents' fees, subject to advance approval by XL

          in connection with the Operations.

          information technology and telecommunications systems including but
          not limited to hardware and software required under the terms of this
          Agreement ("IT Separation") (for which a work schedule which will be
          regularly updated by Winterthur up to Completion will promptly be
          provided to XL Insurance) not be finished by Completion the parties
          shall co-operate and use all reasonable endeavours to finalise the IT
          Separation as soon as is practicable after Completion.

     15.11.2 Subject to Clause 15.8.3 Winterthur will be responsible for all
          reasonable costs incurred in relation to the IT Separation including
          all reasonable costs incurred by XL Insurance and approved by
          Winterthur in advance in writing after Completion . In respect of sums
          claimed under this Clause 15.8.2 XL Insurance will provide Winterthur
          with an invoice setting out clearly that to which the costs relate.

     15.11.3 In order to minimise the security risks to Winterthur Group and XL
          Insurance's Group after Completion resulting from there being shared
          IT infrastructure between members of the

                                      -61-


          Winterthur Group and the Operations Winterthur and XL Insurance agree
          to act in good faith and co-operate with each other and until IT
          Separation is finalised agree that:

          (a)  XL Insurance shall not create additional electronic or physical
               links between the Operations' IT infrastructure and that of any
               third parties (including XL Insurance) without the prior written
               consent of Winterthur (such consent not to be unreasonably
               withheld);

          (b)  both parties shall comply with Winterthur's IT security standards
               as amended from time to time;

          (c)  where it is possible to do so without loss of confidentiality XL
               Insurance shall allow Winterthur or its representatives to
               monitor the Operations' IT infrastructure to ensure compliance
               with this Clause 15.8.3 and to do all that is reasonably
               necessary to rectify any non-compliance discovered;

          (d)  both parties shall co-operate in promptly identifying any
               security breaches and resolving such breaches forthwith; and

          (e)  Winterthur shall immediately sever the link between its IT
               infrastructure and that of the Operations should serious security
               breaches be identified which are not able to be or have not been
               resolved within a reasonable time.

15.12 Administration of Winterthur International (Re)

     XL Insurance shall, after Completion, manage and administer the run-off of
     all reinsurance written or ceded by Winterthur International (Re) prior to
     the Effective Time. XL Insurance shall consult with Winterthur on a regular
     basis in respect of such management and administration, up to and including
     the Final Date (as defined below) but, for the avoidance of doubt, not
     thereafter. Winterthur shall second such employees of Winterthur at actual
     cost as XL Insurance may reasonably require to XL Insurance or any Group
     Company in order for XL Insurance to conduct effectively such management
     and administration. Winterthur shall pay to XL Insurance within 15 Business
     Days of submission of an invoice by XL Insurance in relation thereto (such
     invoice to be submitted on a quarterly basis and to contain reasonable
     detail to support the amount being invoiced) an amount equal to all
     interest expenses paid and foregone (including in respect of deposits with
     reinsurers) and 90 per cent of each non-insurance liability, expense or
     cost including reasonable internal management time spent by employees of
     any member of the XL Insurance Group arising directly or indirectly in
     respect of the above management and administration and incurred by XL
     Insurance or any Group Company on or before the Final Date. However for the
     avoidance of doubt Winterthur shall remain liable for all liabilities,
     expenses and costs arising directly or indirectly from the employment of or
     the termination of the employment of any individual seconded to XL
     Insurance or any Group Company. For the purposes of this clause the "Final
     Date" shall mean the date on which XL Insurance's Accountants have
     determined that all accounting and administrative records are, in all
     material respects, up to date in respect of all such Policies. Interest in
     relation to amounts due under this clause shall run from the date on which
     payment is due hereunder until the date such payment is made at a
     non-compounding rate per annum of 0.5 per cent above the Base Rate.

15.13 Settlement of Inter-Company Accounts

     15.10.1 Winterthur shall procure that Winterthur's Accountants shall, on or
          before 31 August 2001, calculate: (i) the aggregate amounts in the
          Inter-Company Accounts which are receivable by any Group Company from
          any member of the CS Group; and (ii) the aggregate amounts in the
          Inter-Company Accounts which are receivable by any member of the CS
          Group from any Group Company, and Winterthur shall provide a
          certificate to XL Insurance detailing each of the aggregate amounts
          referred to in (i) and (ii) above.

     15.10.2 XL Insurance and XL Insurance's Accountants shall be entitled to
          review and verify the accuracy of the amounts referred to in such
          certificate and XL Insurance shall notify Winterthur in writing within
          45 days of receipt of such certificate as to whether it agrees with
          the amounts detailed in the certificate. In the event that XL
          Insurance does not so agree with the amounts contained in such
          certificate, then the parties shall use their best endeavours acting
          in good faith to reach agreement as to the relevant amounts, and if
          they fail to reach agreement within 14 days thereof, shall together,
          immediately thereafter, appoint the

                                      -62-


          Reporting Accountants who shall determine such amounts and issue a
          certificate in relation thereto to the parties, such certificate being
          final and binding.

     15.10.3 In the event that XL Insurance agrees that the amounts referred to
          in the above certificate are accurate, or, failing such agreement, if
          the Reporting Accountants have issued a certificate, then if the
          aggregate amount in (i) above exceeds the aggregate amount in (ii)
          above as referred to in the relevant certificate, Winterthur shall pay
          to XL Insurance the amount of the excess in US Dollars thereafter, and
          if the aggregate amount in (ii) above exceeds the aggregate amount in
          (i) above as referred to in the relevant certificate, XL Insurance
          shall pay to Winterthur the amount of such excess in US Dollars, in
          each case either such payment being made within 15 Business Days
          following the date on which XL Insurance agrees to the certificate
          issued by Winterthur's Accountants, or the date of issue of the
          Reporting Accountants' certificate.

     15.10.4 Interest in relation to amounts due under this Clause 15.10 shall
          run from the date on which payment is due hereunder until the date
          such payment is made at a non-compounding rate per annum of 0.5 per
          cent above the Base Rate.

15.11 German Reorganization

     Winterthur shall not account for goodwill in relation to the German
     reorganisation in a way which might reasonably be expected to have any
     adverse effect on Winterthur International Insurance Company Limited
     without the prior written approval of XL Insurance.

15.12 Interim Reinsurance Agreements

     All executed Interim Reinsurance Agreements shall be held in escrow to the
     order of the relevant party (by its legal advisers) for a maximum of 5
     Business Days after execution and during such time the parties shall use
     reasonable endeavours, and procure that the other Sellers or Purchasers as
     appropriate use reasonable endeavours to agree any amendments to such
     agreements as may be necessary solely to ensure the enforceability of such
     agreements and their compliance with Applicable Laws. Whether or not any
     such amendments have been agreed by 31 July 2001, the Interim Reinsurance
     Agreements (or amended versions thereof as the case may be) shall be
     released from escrow at the close of business on such date.

16.  Restrictions

                                      -63-

          Group Company or a Business at any time during the 12 months prior to
          the date of this Agreement to cease to deal with a Group Company or a
          Business on substantially equivalent terms to those previously offered
          or at all.

16.5 Exceptions Notwithstanding Clause 16.1 nothing shall prevent the Sellers or
     any other member of the Winterthur Group from time to time from:


     16.5.1 being interested for passive investment purposes only in any class
          of securities in any company provided that such securities are traded
          on a recognised investment exchange, such interest is of a financial
          or investment (and not operational or trading) interest only and not
          more than 10 per cent of such securities are acquired or otherwise
          held in aggregate by all members of the Winterthur Group;

     16.5.2 fulfilling their obligations under the Service Level Agreement; and

     16.5.3 continuing to conduct any of the Operations on behalf of the
          Purchaser after Completion as contemplated by this Agreement.

16.6 Restrictions on the Purchasers

     XL Insurance and the other Purchasers undertake with the Sellers and their
     successors in title that the Purchasers will not and will procure that no
     other member of the XL Insurance Segment (as defined by XL Insurance for US
     Securities Exchange Act reporting purposes) will directly or indirectly or
     in any Relevant Capacity during the Restricted Period induce or solicit or
     seek to induce or solicit any present employee of any of the SRS or motor
     insurance units of any member of the Winterthur Group who would be a Senior
     Employee to become employed or engaged whether as employee, consultant,
     agent, advisor or otherwise by any of the Group Companies or the Businesses
     or XL Insurance or any member of the XL Insurance Segment provided that
     this shall not prevent any of the Purchasers or any other such member of
     the XL Insurance Segment from advertising in general solicitation for
     employees or consultants not targeted at employees of such units provided
     that none of XL Insurance or any of the other Purchasers or any other such
     member of the XL Insurance Segment approaches or encourages any third party
     to approach any such person. For the avoidance of doubt this Clause 16.3
     shall not apply in relation to Relevant Employees.

16.7 Restrictions and Undertakings from CS Group

     16.7.1 No member of the CS Group will after Completion use for any purpose
          whatsoever any of the Business Assets or assets of the Group Companies

          disclose any Confidential Information.

          general insurance business or in the case of the CS Group only use the
          name Winterthur in relation to any Restricted Activity.

16.8 Restrictions Cease to Apply

     The restrictions in Clause 16.4 above shall cease to apply to each and
     every member of the CS Group upon it ceasing to be a member of the CS
     Group.

16.9 Reasonableness of Restrictions

     Winterthur and the other Sellers agree that they consider that the
     restrictions contained in this Clause 16 are no greater than is reasonable
     and necessary for the protection of the interest of XL Insurance and any
     other Purchaser or the Sellers as the case may be but if any such
     restriction shall be held to

                                      -64-

     be void but would be valid if deleted in part or reduced in application
     such restriction shall apply with such deletion or modification as may be
     necessary to make it valid and enforceable.

     consideration of XL Insurance entering into this Agreement Winterthur
     hereby unconditionally and irrevocably guarantees to XL Insurance and the
     Purchasers due and punctual performance and observance by the Sellers and
     any member of the Winterthur Group (whether or not such person ceases to be

     any granting of time for such performance or by any assignment by
     Winterthur of the benefit of the Guaranteed Purchaser Obligations or the
     Guaranteed Seller Obligations as applicable in accordance with Clause 17.5.

17.5 Default by a Party to this Agreement

     If and whenever a Purchaser or a Seller defaults for any reason whatsoever

     unremedied) in the performance of any of the Guaranteed Purchaser
     Obligations or the Guaranteed Seller Obligations as applicable XL Insurance
     or Winterthur as applicable shall forthwith upon demand unconditionally and
     irrevocably perform or procure performance of and satisfy or procure the
     satisfaction of the Guaranteed Purchaser Obligations or the Guaranteed
     Seller Obligations as applicable in regard to which such default has been
     made in the manner prescribed by this Agreement or any agreement entered
     into pursuant to this Agreement (insofar as applicable) and so that the
     same benefits shall be conferred on Winterthur or XL Insurance as
     applicable as it would have received if the Guaranteed Purchaser
     Obligations or the Guaranteed Seller Obligations as applicable had been
     duly performed and satisfied by the relevant Purchaser.

17.6 Continuing Guarantee

     This guarantee is to be a continuing guarantee and accordingly is to remain

     satisfied. This guarantee is in addition to and without prejudice to and
     not in substitution for any rights or security which Winterthur or XL

     observance of the Guaranteed Purchaser Obligations or the Guaranteed Seller
     Obligations as applicable.

     Winterthur agrees that any of the Guaranteed Purchaser Obligations or the
     Guaranteed Seller Obligations as applicable including without limitation
     any monies payable which may not be enforceable against or recoverable from
     any Purchaser or Seller as applicable by reason of any legal limitation,
     disability or incapacity on or of the Purchaser or Seller as applicable or
     any other fact or circumstance other than any limitation imposed

                                      -65-

     by this Agreement or any agreement entered into pursuant to this Agreement
     shall nevertheless be enforceable against and recoverable from XL Insurance
     or Winterthur as applicable as though the same had been incurred by XL
     Insurance and XL Insurance or Winterthur as applicable were the sole or
     principal obligor in respect thereof and shall be performed or paid by XL
     Insurance or Winterthur as applicable on demand.

17.8 Other restrictions, etc.

     This guarantee shall not be affected or impaired by reason of any other
     fact or event which in the absence of this provision would or might
     constitute or afford a legal or equitable discharge or release or a defence
     to a guarantor.

          Agreement or Clause 18.4 in respect thereof) by XL Insurance otherwise

          information to its counsel or other legal advisers in contemplation of
          proceedings being brought in relation to or arising out of this
          Agreement, prior to disclosure of any information pursuant to
          paragraphs (i), (ii) or (iii) of this Clause 18.4.3 the party
          concerned shall promptly notify the other party of such requirement
          with a view to providing the other party with the opportunity to
          contest such disclosure or otherwise to agree the timing and content
          of such disclosure.

     18.7.6 In the event that Winterthur proposes that any member of the
          Winterthur Group (other than Winterthur itself) which may owe
          obligations to any member of the XL Group under this Agreement or
          agreements made pursuant to this Agreement should cease to be such a
          member (the "Departing Member"):

          (i)  provided the guarantee in Clause 17 continues to apply to the
               Departing Member, Winterthur shall have no obligation to consult
               with or seek the approval of XL Insurance in connection
               therewith; and

          (ii) the provisions of Clause 18.4.2 shall not prohibit disclosure or
               use if and to the extent that Winterthur, acting reasonably,
               discloses to potential purchasers (and members, advisers and
               agents of the selling and potential purchasing groups)
               information in relation to the express obligations and rights of
               the Departing Member under the Local Agreements for the purposes
               of the proposed sale, provided that (a) Winterthur shall ensure
               that all such persons are bound by confidentiality obligations at
               least as wide as Winterthur's obligations under this Clause 18
               (but such obligations need not be owed to XL Insurance or any
               Group Company) and provided that Winterthur remains liable for
               any breach of this Clause 18 as a result of disclosure by any
               such person; and (b) Winterthur shall, before entering into
               detailed negotiations with any potential purchaser (which
               expression shall not include exploratory negotiations to

                                      -68-

               ascertain expressions of interest from potential purchasers),
               inform XL Insurance (which shall keep such information
               confidential) of the fact of the proposed sale and the identity
               of the Departing Member (but for the avoidance of doubt
               Winterthur shall not be obliged to give any information about
               potential purchasers).

     18.7.7 In the event that XL Insurance proposes that any member of the XL
          Insurance Group (other than XL Insurance itself) which may owe
          obligations to any member of the Winterthur Group under this Agreement
          or agreements made pursuant to this Agreement should cease to be such
          a member (the "Departing Member"):

          (i)  provided the guarantee in Clause 17 continues to apply to the
               Departing Member, XL Insurance shall have no obligation to
               consult with or seek the approval of Winterthur in connection
               therewith; and

          (ii) the provisions of Clause 18.4.2 shall not prohibit disclosure or
               use if and to the extent that XL Insurance, acting reasonably,
               discloses to potential purchasers (and members, advisers and
               agents of the selling and potential purchasing groups)
               information in relation to the express obligations and rights of
               the Departing Member under the Local Agreements for the purposes
               of the proposed sale, provided that (a) XL Insurance shall ensure
               that all such persons are bound by confidentiality obligations at
               least as wide as XL Insurance's obligations under this Clause 18
               (but such obligations need not be owed to Winterthur) and
               provided that XL Insurance remains liable for any breach of this
               Clause 18 as a result of disclosure by any such person; and (b)
               XL Insurance shall, before entering into detailed negotiations
               with any potential purchaser (which expression shall not include
               exploratory negotiations to ascertain expressions of interest
               from potential purchasers), inform Winterthur (which shall keep
               such information confidential) of the fact of the proposed sale
               and the identity of the Departing Member (but for the avoidance
               of doubt XL Insurance shall not be obliged to give any
               information about potential purchasers).

18.8 Successors and Assigns

     18.8.1 Subject to Clause 18.5.2 save as expressly provided elsewhere in
          this Agreement this Agreement is personal to the parties to it.
          Accordingly neither the Purchasers nor the Sellers may without the
          prior written consent of Winterthur or XL Insurance respectively
          assign the benefit of all or any of the obligations of any other party
          under this Agreement nor any benefit arising under or out of this
          Agreement or any Local Agreement.

     18.8.2 Except as otherwise expressly provided in this Agreement either the
          Sellers or a Purchaser may without the consent of the other parties
          assign to an Associated Company the benefit of all or any of any other
          party's obligations under this Agreement or any Local Agreement
          provided that if the assignee ceases to be an Associated Company of
          Winterthur or as the case may be XL Insurance then Winterthur or as
          the case may be XL Insurance shall procure that the assignee
          re-assigns the benefit of the assigned obligations to an Associated
          Company before the assignee ceases to be such an Associated Company
          and provided further that the maximum liability of any party for
          breach of this Agreement or under any indemnity contained in or
          entered into pursuant to this Agreement shall be limited to the
          liability which would have arisen in the absence of any such
          assignment by the Sellers or XL Insurance.

                                      -69-

          Agreement, except that the various persons identified in Clauses
          2.3.1, 2.3.2, 4.3 and 9 (including any Group Company) shall be express
          third party beneficiaries of the provisions contained in such clauses.

          case of a Seller) and XL Insurance (in the case of any Purchaser or
          Group Company) to act as its trustee or agent to enforce such
          provisions on its behalf (and may not enforce such provisions save
          through such trustee or agent) and each of Winterthur and XL Insurance
          accept the above appointments.

     18.9.2 Winterthur (on behalf of any Seller) and XL Insurance (on behalf of
          any Purchaser and, following Completion, any Group Company) may amend,
          modify, waive or otherwise affect any rights or obligations of any

          respectively, under this Agreement.

     it. The costs of the Reporting Accountants and the Independent Actuary
     shall be borne by the parties equally.

     XL Insurance default in the payment when due of any sum payable under this
     Agreement or any Local Agreement (whether determined by agreement or

     or XL Insurance (as the case may be) shall unless otherwise provided be
     increased to include interest on such sum from the date when such payment
     is due until the date of actual payment (as well after as before judgment)
     at a non-compounding rate per annum of 4 per cent above the Base Rate. Such

18.16 Withholding and Deductions/VAT

     18.16.1 All sums payable by any party to another party under this Agreement
          (including for the avoidance of doubt payments under Clause 4.3) shall
          be paid free and clear of all deductions, withholdings, set-offs or
          counter-claims whatsoever save only as may be required by law. If any
          deductions or withholdings are required by law the payer shall (except
          to the extent the same has been taken into account in calculating the
          amount due under any other provision of this Agreement) be obliged to
          pay to the payee such sum as will after such deduction or withholding
          has been made leave the payee with the same amount as it would have
          been entitled to receive in the absence of any such requirement to
          make a deduction or withholding.

     18.16.2 If any Taxation authority charges to Taxation any sum paid to any
          party by another party under any indemnity contained in this Agreement
          (except to the extent the same has been taken into account in
          calculating any amount due under any other provision of this
          Agreement) then the amount so payable shall be grossed up by such
          amount as will ensure that after payment of the Taxation so charged
          there shall be left a sum equal to the amount that would otherwise be
          payable under this Agreement provided that in determining the amount
          payable under this Clause 18.13.2 there shall be taken into account
          any deduction arising no later than the end of the period in which the
          charge to tax arises which is or will be available for Taxation
          purposes to the payee or any group of companies of which the payee is
          a member in respect of the matter in relation to which such sum is
          paid.

     18.16.3 To the extent that the payee is satisfied (acting in good faith) it
          can so do without prejudice to the retention of any credit refund or
          similar benefit it receives if the payee receives a credit for or
          refund of any Taxation payable by it or similar benefit by reason of
          any deduction or withholding for or on account of Taxation it shall
          reimburse to the payer such part of such additional amounts paid to it
          pursuant to Clause 18.13.1 as the payee certifies to the payer will
          leave it (after such reimbursement) in no better and no worse position
          than it would have been if the payer had not been required to make
          such deduction or withholding. The payee shall use all reasonable
          endeavours to obtain any available credit, refund or similar benefit.

     18.16.4 If any deduction or withholding is made from any payment as
          contemplated in Clause 18.13.1 the payer shall supply to the payee
          such official receipt if any or other evidence of payment to

                                      -71-

          the relevant authority of the amount deducted or withheld and shall
          give all reasonable assistance to enable the payee to receive a credit
          or refund or similar benefit by reason of the deduction or withholding
          as promptly as possible.

     18.16.5 Where for the purpose of any provision of this Agreement (including
          without limitation any provisions concerning reimbursement,
          indemnification or compensation) any amount is to be determined or
          calculated by reference to any amount incurred or to be incurred by
          any person such part of such latter amount as represents VAT in
          respect of which such person is entitled to credit or repayment from
          the relevant Tax authority shall be excluded for the purpose of such
          determination or calculation.

18.17 Severance

     If any term or provision of this Agreement is held to be illegal or
     unenforceable in whole or in part under any enactment or rule of law such
     term or provision or part shall to that extent be deemed not to form part
     of this Agreement but the enforceability of the remainder of this Agreement
     shall not be affected.

18.18 Counterparts

     This Agreement may be executed in any number of counterparts each of which
     shall be deemed an original but all the counterparts shall together
     constitute one and the same instrument.

18.19 Further Assurances

     all further documentation or procure that all reasonable action is taken
     and all further documentation is executed so as to give full effect to the

     entering into such agreements as are necessary or appropriate to give
     effect to Winterthur's obligations and covenants referred to in Clause
     15.4: (ii) both parties complying with the provisions of Schedule 5; and
     (iii) both parties entering into appropriate reinsurance agreements
     (reflecting substantially the same overall economic effect on the relevant
     party and other terms otherwise contemplated hereby) to the extent
     necessary so that the relevant member of the XL Insurance Group or the
     Winterthur Group can obtain reinsurance credit for applicable regulatory
     purposes.

18.20 Set Off

     Any amount due to be paid to any of the Sellers hereunder by any of the
     Purchasers shall be decreased by any amount which, at the relevant time, is
     due to be paid to any of the Purchasers hereunder by any of the Sellers.
     Any amount due to be paid to any of the Purchasers hereunder by any of the
     Sellers shall be decreased by any amount which, at the relevant time, is
     due to be paid to any of the Sellers hereunder by any of the Purchasers.
     For the purposes of this Clause 18.17, an amount should be deemed 'due' if
     and only if (i) it has been so agreed in writing by Winterthur and XL
     Insurance, (ii) it has been determined or is deemed to be the case in
     accordance with this Agreement or any other agreement referred to herein,
     or (iii) it has been determined or declared by court or administration
     order.

     courts of England are to have non-exclusive jurisdiction to settle any
     disputes which may arise out of or in connection with this Agreement
     provided that this Clause 18.18 shall not preclude the enforcement of any
     Local Agreement in the courts of the relevant jurisdiction in a manner
     consistent with Clause 2.6.
