such payment or benefit constituting an "excess parachute payment" within the
meaning of Section 280G of the Code in connection with a change in the
ownership or effective control, of a corporation, or a substantial portion of
the assets or a corporation (within the meaning of Sections 280G of the Code,
in each case arising out of or resulting from the consummation of the

     consent of Purchaser provided under Section 7.2.4 shall not apply to this
     Section 7.2.6, including this clause (d).

the offices, properties, assets, books and records of the Acquired Group and

reasonably requested from time to time by Purchaser and in ABB's good faith
and reasonable judgment can be prepared by ABB or any Acquired Company without

other matters required to be performed in accordance with this Agreement.
Neither ABB nor any of its Affiliates shall be under an obligation to disclose
to Purchaser or its representatives any information the disclosure of which,
according to the advice of ABB's legal counsel, is restricted by
confidentiality obligations or applicable Law or would jeopardize the legal
privilege, if any, accorded to any documents produced or prepared by the legal
representatives of ABB or its Affiliates. No investigation or access to
information pursuant to this Section 7.3 shall affect any representation or
warranty or covenant made by ABB to Purchaser hereunder or otherwise affect

Affiliates, retain all books, records and other documents pertaining to the
businesses of the Acquired Group in existence on the Closing Date and to make
the same available for inspection and copying by ABB or its Affiliate or
representatives thereof during reasonable business hours, upon reasonable
request and upon reasonable notice. No such books, records or documents shall

the Closing Date. ABB shall calculate and the parties shall use all reasonable
efforts to agree to a transfer payment amount with respect to each Employee
who participates in such Retained Plans in accordance with each such Retained

transfer payment amount shall be payable by ABB to an available plan operated
by the Purchaser or any of its Affiliates, of which the relevant Employee is a
member, or to another plan or arrangement nominated by such Employee.

          (c)   ABB shall cause the Acquired Group to include as an accrued
liability on the Audited Closing Financial Statements to the extent required
by U.S. GAAP any bonuses (other than those set forth on Section 5.12.5 of the
Disclosure Schedule) payable by an Acquired Company after the Measurement Date

any provision of this Agreement or (ii) the execution of this Agreement or the
consummation of the transactions contemplated hereby, shall be fully accrued
on the Audited Closing Financial Statements to the extent required by U.S.
GAAP. Upon request and proof of payment, ABB shall reimburse the relevant
Acquired Company for any and all payments made after the Measurement Date and
not accrued on the Audited Closing Financial Statements required to be paid by

Closing if done with the prior written consent of Purchaser, or (iii) the
requirements of collective bargaining agreements disclosed in Section 5.12.5
of the Disclosure Schedule.

7.6.      Taxes

          (a)   ABB shall, in a manner consistent with past practice, cause, and

any other Tax Returns that ABB determines are due on or prior to the Closing
Date, with respect to the assets, income or operations of each Acquired
Company; and (ii) pay all Taxes shown on such Tax Returns due and payable on
or prior to the Closing Date; provided, however, that ABB shall permit
Purchaser to review and comment on any Tax Return (to the extent, and only to
the extent, it relates to any period after the Measurement Date) prior to
filing and no Tax Returns which relate to any period after the Measurement
Date shall be filed without the written consent of Purchaser (which consent
shall not be unreasonably withheld or delayed).

          (b)   Except as provided in paragraph (a) of this Section 7.6,

Acquired Group; provided,


                                     -56-





however, that with respect to Tax Returns covering a taxable period beginning
on or prior to the Measurement Date and ending after the Measurement Date
("Straddle Period"), Purchaser shall treat items on such Tax Returns in
accordance with past practice of ABB and the Acquired Group and shall allow
ABB to review and comment on such Tax Returns prior to filing and no such Tax
Returns shall be filed without the prior written consent of ABB (which consent
shall not be unreasonably withheld or delayed).

          (c)   ABB shall cause each Acquired Company to terminate and discharge
on or prior to the Closing Date, without further liability or obligation
thereunder, any Tax sharing agreement, Tax indemnity obligation or similar

directors (or other comparable managing body) and elect new auditors.
Purchaser shall ensure that, promptly thereafter, each Acquired Company makes
all necessary filings with the relevant governmental authorities and takes all
other necessary action to register in the applicable public registry, if
required, the resignation of the retiring board members and the matters
decided pursuant to this Section 7.7.1.

          Purchaser shall procure that, at the first shareholders' meeting or
otherwise whenever the question of discharge is raised after the Closing, each
member of the board and, where applicable, the managing director of each
Acquired Company is discharged in full from any liability as a member of the
board or managing director, as the case may be, in relation to the period
prior to the Closing, provided that the auditor of such Acquired Company has
recommended such discharge.

7.8.      No Solicitation/no Hire of Employees

          For a period of eighteen (18) months from the Closing, ABB shall
not, and shall cause its Affiliates not to, directly or indirectly, solicit
for employment or employ any Employee, without the prior written consent of
Purchaser; provided that: (i) the placing of an advertisement of a post
available to a member of the public generally, the hiring of any Employee in
response to such an advertisement shall not constitute a breach of this
Section 7.8; and (ii) this obligation shall not prevent ABB or any of its
Affiliates from employing, mandating or otherwise engaging any Employee whose
employment with Purchaser or its relevant Affiliate has been terminated by
Purchaser or any of its Affiliates.


                                     -57-





7.9.      No Solicitation of Offers

          From the date of this Agreement, ABB shall not, nor shall it permit
any of its Affiliates to, nor shall they authorize any of their directors,
officers or employees or any investment banker, financial advisor, attorney,
accountant or other representative retained by them or any of their Affiliates
to, and they shall use all reasonable efforts to ensure that such persons do
not, directly or indirectly, (i) solicit, initiate or encourage (including by
way of furnishing information), or take any other action designed to
facilitate, any inquiries or the making of any proposal which constitutes, or
is likely to lead to any proposal to acquire all or any significant portion of
any Acquired Company or (ii) participate in any discussions or negotiations
regarding any such proposal.

within the terms of Section 5.10.1(h) or any Material Contract; or (vi) any
change in the officers or directors of any Acquired Company.

          (b)   ABB covenants and agrees to notify Purchaser of any governmental
complaints, investigations or hearings or adjudicatory proceedings involving
any material property or asset of any Acquired Company and will keep Purchaser
reasonably informed of such events and permit Purchaser's representatives
reasonable access to all materials prepared by or on behalf of ABB or its
Affiliates in connection therewith (except where, in the good faith judgment
of ABB, the disclosure of any documents produced or prepared by the legal
representatives of ABB or its Affiliates would reasonably be expected to
jeopardize the legal privilege otherwise accorded such documents).

7.10.2    Notices by Purchaser

          Purchaser covenants and agrees to give prompt notice in writing to
ABB of: (i) any information evidencing that any representation or warranty
given by it herein was not true and correct as of the date hereof or will not
be true and correct as of the Closing Date; (ii) the occurrence of any event
which will, or is reasonably likely to, result in the failure to satisfy a
condition specified in Section 8.1 or 8.3; or (iii) any written notice or
other written communication from any third party alleging that the consent of
such third party is or may be required in connection with the transactions
contemplated by this Agreement.


                                     -58-





7.10.3    Consequences of Notices

          The giving of any notice under this Section 7.10 shall in no way
change or modify ABB's or Purchaser's representations and warranties and
covenants or the conditions to any party's obligations contained herein or
otherwise affect the remedies available to Purchaser or ABB hereunder.

7.11.     Intercompany Accounts

          Except as otherwise specifically provided in this Agreement, ABB
shall cause all intercompany accounts receivable or payable (whether or not
currently due or payable) in an aggregate amount in excess of SEK 800,000 (or
its foreign currency equivalent), including any amounts receivable or payable
in connection with any Affiliate Contract, other than Direct Insurance
Agreements, Assumed Reinsurance Agreements or Ceded Reinsurance Agreements,
between (i) any member of the Acquired Group, on the one hand, and (ii) ABB,
any of its Affiliates (other than the Acquired Companies), or any of their
respective officers, directors or employees, on the other hand to be settled
in full (without any premium or penalty) at or prior to the Closing. Within
five (5) Business Days prior to the Closing, ABB shall prepare and deliver to
Purchaser a preliminary statement setting out in reasonable detail the
calculation of all such intercompany account balances as of such date based
upon the latest available financial information as of such date. ABB shall
deliver to Purchaser reasonable supporting documentation verifying the
underlying intercompany charges and transactions.

7.12.     Investment Portfolio

correct list of all investments constituting the Investment Portfolio as of
the end of such month, the issuer of such investments, the nominal amount
owned and the market value with respect to public investments (or book value
with respect to private investments) of such investments as of the end of such
month.

7.13.     Assignment of Confidentiality Agreements

          Prior to or at the Closing, ABB shall cause any confidentiality
agreements entered into by ABB or any of its Affiliates since January 1, 2002
relating solely to the Business or any properties, assets, liabilities or
activities of any Acquired Company in connection with a sale or disposition of
the Business or a part thereof that are not agreements to which an Acquired
Company is a party to be assigned to an Acquired Company unless prohibited by
the terms of such confidentiality agreement.

7.14.     Amendment of Leases

          Prior to the Closing, ABB shall use its reasonable efforts to cause
the leases under which ABB or any of its Affiliates (other than an Acquired
Company) leases any real property used by an Acquired Company immediately
prior to the execution of this Agreement to be amended, to the extent
necessary, to permit such Acquired Company to directly lease such real
property after the Closing on terms and conditions consistent in all material
respects with the terms under which ABB or its Affiliates lease such property.

7.15.     Sirius Belgium

          After the Closing, Purchaser agrees that: (i) it shall not liquidate
Sirius Belgium prior to the full realization of all refunds, credits or
offsets of Taxes described in Section 9.6.4(b) (including the final settlement
of any Tax Claims relating thereto); and (ii) it shall reasonably cooperate
with ABB and follow ABB's reasonable instructions (at the expense of ABB) in
the liquidation of Sirius Belgium as soon as practicable after its receipt of
any refunds, credits or offsets contemplated in clause (i) above.

7.16.     Access to Purchaser Auditors

          From the delivery of the Audited Closing Financial Statements to ABB
and Purchaser pursuant to Section 3.4.2 until the Closing, ABB shall afford
Purchaser's auditors, employees and representatives such reasonable access as
they may from time to time reasonably request, during normal business hours
and in a manner which is not disruptive to the operations of the Business or
the business of ABB or any of its Affiliates to the Acquired Group's and each
member of the Acquired Group's respective officers, employees, agents,
accountants (including the Business Auditors) and actuaries and to the
premises, properties, books, accounting records and other documents (including
supporting contractual documentation and the work papers of the Business
Auditors relating to the audit of the Financial Statements and the Audited
Closing Financial Statements, provided that Purchaser's auditors, employees
and representatives have signed any release letter reasonably required by the
Business Auditors in connection therewith) of the Acquired Group or available
to the Acquired Group, in each case solely for the purpose of enabling
Purchaser's auditors, employees and representatives to prepare and audit a
consolidated balance sheet of the Acquired Group as of December 31, 2003,
together with related consolidated income statements and statements of cash
flow for the twelve month period then ended.

7.17.     Facility Agreement

          ABB shall promptly after the date of this Agreement commence such
actions as shall be reasonably necessary to enable it to obtain the
certificates from the Pledge Agent and Lenders required to be delivered
pursuant to Section 8.2(d).

7.18.     Purchaser Disclosure Procedures

          Prior to the Closing, ABB shall permit Purchaser to liaise with the
Senior Executives to ensure that such controls and procedures as Purchaser
intends to implement for the Acquired Group as and from the Closing to satisfy
its obligations under Rules 13a-15(e) and (f) and 15d-15(e) and (f)
promulgated under the U.S. Securities Exchange Act of 1934, as amended, can
reasonably be implemented with effect from the Closing. Nothing in this
Section 7.18 shall require ABB to implement any such controls and procedures
prior to the Closing.

7.19.     Dividends

          (a)   In the event that ABB proposes to authorize any Acquired Company
to make the ABB Distribution prior to the delivery by ABB of the Unaudited
Closing Financial Statements pursuant to Section 3.4.1, ABB shall prepare in
good faith and in consultation with the Business Auditors: (i) an unaudited
consolidated balance sheet of the Acquired Group as of December 31, 2003,
together with a related unaudited consolidated income


                                     -60-





statement for the twelve month period then ended, each in accordance with U.S.
GAAP, as applied by the ABB Group in its U.S. GAAP ABACUS reporting system and
in the form of Schedule 3.4.1(2) (the "ABACUS Financial Statements"); and (ii)
a statement showing the calculation of Net Equity (the "ABACUS Net Equity"),
determined on the basis of the ABACUS Financial Statements and taking into
account the adjustments set out in Schedule 3.4.1(1) (the "ABACUS Net Equity
Statement"), and shall deliver such ABACUS Financial Statements and ABACUS Net
Equity Statement to Purchaser at least five (5) Business Days prior to the
date of the ABB Distribution.

          (b)   Within 30 days after the Measurement Date, ABB, after consulting
with its auditors, shall deliver to Purchaser a certificate setting forth the
maximum amount, in Swedish kronor (the "Permitted ABB Distribution Amount"),
that ABB in its good faith and reasonable judgment believes that the Acquired
Group may distribute to ABB or any of its Affiliates (other than the Acquired
Companies) under applicable Law. ABB shall cause a member of the Acquired
Group to pay a dividend or other distribution (the "ABB Distribution") to ABB
or any of its Affiliates (other than an Acquired Company) after the
Measurement Date and prior to the Closing but no earlier than five (5)
Business Days after delivery of (i) the Unaudited Closing Financial Statements
and Unaudited Closing Net Equity Statement pursuant to Section 3.4.1 or (ii)
the ABACUS Financial Statements and ABACUS Net Equity Statement pursuant to
this Section 7.19, which ABB Distribution shall be in an amount (the "ABB
Distribution Amount") equal to the lesser of:

          (x)   the Permitted ABB Distribution Amount;

          (y)   (A) the amount by which the ABACUS Net Equity exceeds the
     Guaranteed Net Equity if the Unaudited Closing Financial Statements have
     not been delivered to Purchaser at least five (5) Business Days prior to
     the date of the ABB Distribution; (B) the amount by which the Unaudited
     Net Equity exceeds the Guaranteed Net Equity, if the Audited Closing
     Financial Statements have not been delivered to Purchaser at least five
     (5) Business Days prior to the date of the ABB Distribution; (C) the
     amount by which the Audited Net Equity exceeds the Guaranteed Net Equity,
     if the Final Closing Financial Statements have not been delivered to
     Purchaser at least five (5) Business Days prior to the date of the ABB
     Distribution; or (D) the amount by which the Final Net Equity exceeds the
     Guaranteed Net Equity, if the Final Closing Financial Statements have
     been delivered to Purchaser at least five (5) Business Days prior to the
     date of the ABB Distribution; or

          (z)   such lesser amount as ABB proposes and has been approved by
     Purchaser (such approval not to be unreasonably withheld or delayed);
     provided, however, that, without prejudice to Purchaser's right of
     approval generally, it shall not be unreasonable for Purchaser to
     withhold its consent if it or any of its Affiliates would (i) suffer any
     economic loss (other than an immaterial loss) or (ii) incur any financing
     costs.

          (c)   The parties agree that, notwithstanding any other provisions of
this Agreement, Sirius Holding may pay the Sirius Holding Dividend to ABB or
any of its Affiliates prior to the Measurement Date.

7.20.     Abb Intellectual Property

7.20.1    Branded Assets

          To the extent any trademarks, registered or unregistered (including
logos or other devices), or any trading names owned by ABB or any of its
Affiliates (other than the Acquired Companies) (including, for the avoidance
of doubt, the words "ABB", "BBC", "Asea", "Brown" or "Boveri") are included in
any business stationery, brochures, technical literature, drawings and other
documents, or are displayed on any premises, signs, vehicles or uniforms,
which are owned by any Acquired Company (collectively, "Branded Assets"),
Purchaser may, for a period of sixty (60) days after the Closing Date, use
such Branded Assets, after which date it shall cross out, mark over or
otherwise cover or redact such references and otherwise clearly indicate on
such Branded Assets that the Business is no longer owned by ABB or any of its
Affiliates (other than the Acquired Companies).

7.20.2    No Other Use

          Except as permitted by Section 7.20.1, Purchaser shall not, and
shall procure that none of its Affiliates shall, after the Closing, use in any
way whatsoever any registered or unregistered trademarks, including any logos
or other devices, or any trading names which are owned by ABB or any of its
Affiliates (other than the Acquired Companies) (including, for the avoidance
of doubt, any reference to "ABB", "BBC", "Asea", "Brown" or "Boveri").

7.21.     Amendments to Certain Contracts

          ABB shall use its reasonable efforts to cause each Contract set
forth on Schedule 7.21 to be amended, effective as of the Closing, to permit
each Acquired Company that is a party thereto to directly lease the personal
property subject to such Contract directly from the lessor on the terms
applicable to each Acquired Company under such Contract as at the date of this
Agreement; provided, however, that if amending any such Contract will cause
the aggregate amounts payable, determined on a monthly basis, by the Acquired
Companies that are a party to such amended Contract to increase by more than
20% over the aggregate amounts payable, determined on a monthly basis, by or
on behalf of the same Acquired Companies under the applicable Contract as at
the time immediately prior to the Closing, ABB shall be responsible for 50% of
such excess monthly amounts payable for a period starting from the Closing
Date and ending on the date on which such amended Contract would have
terminated in accordance with its terms and without penalty to any Acquired
Company that is a party thereto, assuming a notice of termination was provided
under such amended Contract on the Closing Date.

7.22.     Employees

          Purchaser agrees to promptly inform ABB of any Contract with any
Employee that it or any of its Affiliates enters into between the date of this
Agreement and the Closing Date that provides for any payments or benefits to
such Employee as a result of any adjustment to the Purchase Price pursuant to
any provision of this Agreement.

     be true and correct, both when made and as of the Closing Date, as if

     such representations and warranties to be so true and correct,
     individually or in the aggregate, has not had and is not reasonably
     likely to result in a Material Adverse Effect (it being agreed that for
     the purpose of calculating whether the effect of breaches of such
     representations and warranties have had or are reasonably likely to
     result in a Material Adverse Effect, but not for the determination of
     breaches themselves, such representations and warranties shall be deemed
     not qualified by any references therein to materiality or Material
     Adverse Effect);

          (b)   ABB shall have performed and complied in all material respects
     with all of its undertakings and agreements required by this Agreement to
     be performed or complied with by it prior to the Closing;

     addressed to Purchaser and White Mountains Insurance Group, Ltd. and date
     the Closing Date;

     Agreement and Pledge Agreement have not been terminated prior to the
     Closing, certificates from the Pledge Agent and each Lender stating: (x)
     the total amount required to be paid to the Lenders to cause them to
     terminate in full the Facility Agreement and the Pledge Agreement (the
     "Lenders' Payment"); and (y) that the Facility Agreement and Pledge
     Agreement shall be deemed terminated as of the Closing Date upon the
     Lenders receipt of the Lenders' Payment on such date, or (ii) if the

     Closing, certificates from the Pledge Agent and each Lender stating: (x)
     the Facility Agreement and Pledge Agreement have been terminated; and (y)
     neither the Facility Agent nor any Lender has any Encumbrances over the
     shares of Sirius International;

          (e)   there shall not be pending any suit, action or proceeding
     brought by any governmental authority (i) challenging or seeking to
     restrain or prohibit the consummation of any of the transactions
     contemplated hereby; (ii) seeking to prohibit or limit in any material
     respect the ownership or operation by any Acquired Company, Purchaser or
     any of their respective Affiliates of a portion of the business,
     Properties or assets of any Acquired Company, any Subsidiary of an
     Acquired Company, Purchaser or any Affiliate of Purchaser or to require
     any such Person to dispose of or hold separate any portion of the
     business, Properties or assets of any Acquired Company, any Subsidiary of
     an Acquired Company, Purchaser or any Affiliate of Purchaser as a result
     of the transactions contemplated hereby; or (iii) seeking to prohibit
     Purchaser, any Acquired Company or any of their Affiliates from
     effectively controlling in any respect the business or operations of any
     Acquired Company or any Subsidiary of an Acquired Company; provided that
     Purchaser or such of its Affiliates as are party to such suit, action or
     proceeding shall use their reasonable efforts to obtain settlement or
     discharge of such suit, action or proceeding, but provided further that
     Purchaser or its Affiliates shall not be required to dispose of or hold
     separate any portion of their businesses or properties or assets, or
     those of the Acquired Group, or to accept any limitations upon the
     ownership or operation by Purchaser or its Affiliates or any Acquired
     Company of a portion of any of the business, properties or assets, in
     connection with any such settlement or discharge; and

          (f)   since the date of this Agreement, there shall not have occurred
     any change in, or effect on, the Acquired Group which individually or in
     the aggregate is, or is reasonably likely to be, materially adverse to
     the financial condition of the Acquired Group, taken as a whole, other
     than changes or effects resulting from (i) changes in general economic
     conditions or financial market conditions (including currency rate
     fluctuations and interest rate changes), (ii) any decline in the value of
     the Investment Portfolio, (iii) catastrophe events with an impact in the
     ordinary course of the Business, (iv) legal or regulatory changes
     affecting the property and casualty insurance or reinsurance industry

     by way of limitation, the full extent of any change that specifically
     relates to any Acquired Company or disproportionately affects any
     Acquired Company shall be considered in determining whether there is, or
     is reasonably likely to be, a material adverse change or effect on the
     financial condition of the Acquired


                                     -64-





     Group) or (v) the announcement of this Agreement or the consummation of
     the transactions specifically contemplated hereby, including the cessation
     of the Financial Risks Business pursuant to Section 7.2.4(dd).

8.3.      Additional Conditions of ABB

          The obligation of ABB to consummate the transactions contemplated
hereby is subject to the fulfillment of the following conditions prior to or
at the Closing (which may be waived by ABB in writing in its sole discretion):

          (a)   the representations and warranties of Purchaser set forth herein
     shall be true and correct, both when made and as of the Closing Date, as
     if made at and as of such time (except to the extent expressly made as of
     an earlier date, in which case as of such date) except where the failure
     of such representations and warranties to be so true and correct,
     individually or in the aggregate, has not materially adversely affected
     and is not reasonably likely to materially adversely affect the ability
     of Purchaser to complete the transactions contemplated hereby (it being
     agreed that for the purpose of calculating whether the effect of breaches
     of such representations and warranties has materially adversely affected
     or is reasonably likely to materially adversely affect the ability of
     Purchaser to complete the transactions contemplated hereby, but not for
     the determination of breaches themselves, such representations and
     warranties shall be deemed not qualified by any references therein to
     materiality);

          (b)   Purchaser shall have performed and complied in all material
     respects with all of its undertakings and agreements required by this
     Agreement to be performed or complied with by it prior to the Closing;

          (c)   Purchaser shall have delivered to ABB a legal opinion from
     Advokatfirman Vinge KB, counsel to Purchaser, substantially in the form

     Conyers, Dill & Pearman, counsel to White Mountains Insurance Group,
     Ltd., substantially in the form of Annex 6, addressed to ABB and dated
     the Closing Date.

8.4.      Frustration of Closing Conditions

             No party may rely on the failure of any condition set forth in
Section 8.1, 8.2 or 8.3, as the case may be, to be satisfied if such failure
was caused by such party's failure, subject to the terms and conditions of this
Agreement, to use reasonable efforts to consummate the transactions
contemplated by this Agreement.

                                   ARTICLE 9
                         LIABILITY AND RELATED MATTERS


9.1.      Indemnification by ABB

          From and after the Closing, ABB shall indemnify Purchaser and its
Affiliates (including, for the avoidance of doubt, the Acquired Companies) and
each of their respective officers, directors, employees, heirs, successors and
assigns against and hold them harmless


                                     -65-





from (whether in connection with a Third Party Claim or a Direct Claim) any
Loss (payable promptly upon agreement between ABB and Purchaser or upon final
determination of ABB's liability pursuant to the provisions of Section 11.10,
for such Third Party Claim or Direct Claim) by any such Indemnified Party
caused by or resulting from:

          (a)   any breach of any representation or warranty of ABB contained in
     Article 5 or in any certificate delivered by or on behalf of ABB at the
     Closing (it being agreed that for purposes of such indemnification, the
     representations and warranties of ABB shall, with respect to calculation
     of Losses only (but not for determination of breaches), be deemed not
     qualified by any references therein to materiality or to the occurrence
     or reasonable likelihood of a Material Adverse Effect);

          (b)   any breach of any obligation of ABB contained in this Agreement;

          (c)   the liabilities of Sirius Holding on a stand-alone basis
     (disregarding any obligations or liabilities of any other Acquired
     Company) incurred prior to the Closing;

          (d)   the Facility Agreement and the Pledge Agreement;

          (e)   the liabilities of Sirius Belgium (other than liabilities
     incurred by Sirius Belgium after the Closing Date as a result of actions
     taken after the Closing Date by Purchaser or its Affiliates (including
     any Acquired Company) and not authorized in writing by ABB);

          (f)   any breaches of Law or Contract resulting from the Sirius
     International Swedish defined contribution funded Retirement Plan having
     been converted from a defined benefit plan to a defined contribution plan
     (any claims alleged in connection with any such breaches to be
     administered in accordance with Section 9.4);

          (g)   any obligation or liabilities relating exclusively to the ABB
     Group (excluding the Acquired Group) for which Purchaser or any of its
     Affiliates (including, for the avoidance of doubt, any Acquired Company)
     becomes liable (excluding, for the avoidance of doubt, any obligations or
     liabilities arising out of Contracts to which an Acquired Company is a
     party); or

          (h)   any Retained Plan, other than a Loss resulting from liabilities
     and obligations included in the calculation of the transfer payment
     amounts applicable to such Retained Plan and agreed by Purchaser and ABB
     in accordance with Section 7.5(b);

provided, however, that ABB shall not be required to indemnify or hold
harmless any Person, and shall not have any liability:

               (i)   under clause (a) of this Section 9.1, other than any
          liability relating to a representation or warranty of ABB contained
          in Sections 5.1, 5.2.1, 5.3, 5.4, 5.20 or 5.21 of this Agreement
          (collectively, the "ABB Specified Claims"), (x) unless the aggregate
          of all Losses relating thereto for which ABB would, but for this
          proviso, be liable exceeds on a cumulative basis an amount equal to
          SEK 55 million, and then only to the extent of any


                                     -66-





          such excess; and (y) for any individual breach where the Loss with
          respect to such individual breach is less than SEK 5 million,
          provided, that (i) the term "individual breach" shall mean each
          individual breach of a particular warranty and not the aggregation
          of individual breaches of a particular warranty into a single breach
          (e.g., if ABB failed to disclose five contracts under a particular
          warranty, and the failure to disclose any one of those contracts
          would be a breach, then the five contracts together would be
          considered multiple breaches, of which each such undisclosed
          contract would be an "individual breach"), and (ii) for purposes of
          the calculation of the Loss with respect to such individual breach,
          a series of separate Losses caused by or resulting from the same
          individual breach shall be aggregated (e.g., if an individual breach
          causes or results in two separate Losses of SEK 3 million each, such
          Losses shall be aggregated to a sum of SEK 6 million for purposes of
          determining whether the "Loss with respect to such individual
          breach" is less than SEK 5 million), provided, however, that this
          clause (i) shall not apply with respect to Losses in respect of a
          failure to disclose in Section 5.10.1(1), 5.10.1(2), 5.10.1(3),
          5.10.1.(4) or 5.10.1(5) of the Disclosure Schedule any Direct
          Insurance Agreement, Assumed Reinsurance Agreement, Ceded
          Reinsurance Agreement, Reinsurance Pool or Scan Re Agreement
          required to be disclosed by ABB pursuant to Section 5.10.1 (the
          "Insurance Agreement Claims"); and

               (ii)  under clause (a) of this Section 9.1 for any Losses in
          excess of an amount equal to 80% of the International Purchase
          Price; provided, however, that this limitation shall not apply to
          any Losses relating to an ABB Specified Claim.

               This Section 9.1 shall not apply to any claim for
          indemnification with respect to any Taxes, which claims shall be
          governed by Section 9.6.

9.2.      Indemnification by Purchaser

          From and after the Closing, Purchaser shall indemnify ABB and its
Affiliates, officers, directors, employees, heirs, successors and assigns
against and hold them harmless from (whether in connection with a Third Party
Claim or a Direct Claim) any Loss payable promptly upon agreement between ABB
and Purchaser or upon final determination of Purchaser's liability pursuant to
the provisions of Section 11.10, as applicable, for such Third Party Claim or
Direct Claim by any such Indemnified Party caused by or resulting from:

          (a)   any breach of any representation or warranty of Purchaser
     contained in Article 6 or any certificate delivered by or on behalf of
     Purchaser at the Closing (it being agreed that for the purposes of such
     indemnification, the representations and warranties of Purchaser shall,
     with respect to calculation of Losses only (but not for determination of
     breaches), be deemed not qualified by any references therein to
     materiality); or

          (b)   any breach of any obligation of Purchaser contained in this
     Agreement;

          (c)   any of the employee benefit, bonus, incentive compensation,
     severance, salary continuation, termination or retention pay, death
     benefit, welfare benefit (including all obligations under Section 4980B
     of the Code and Part 6 of Subtitle B of Title I of the Employee
     Retirement Income Security Act of 1974, as


                                     -67-





     amended), profit-sharing, pension, retirement, deferred compensation,
     medical, life insurance, disability, accident, accrued leave, vacation,
     sick pay, sick leave, unemployment benefit and fringe benefit plans,
     programs and arrangements and employment, consulting, termination,
     retirement and severance contracts and agreements, including the
     Transferred Plans, which transfer to Purchaser or its Affiliates in their
     entirety at or after the Closing by operation of Law, other than (i)
     Losses caused by a failure by ABB and its Affiliates (including the
     Acquired Group) prior to the Closing to comply with Law or the terms of
     such plans, programs, arrangements, contracts or agreements or (ii)
     Losses for which ABB has agreed to indemnify the Purchaser under Section
     9.1;

provided, however, that Purchaser shall not be required to indemnify or hold
harmless any Person, and shall not have any liability:

               (i)   under clause (a) of this Section 9.2, other than any
          liability relating to a representation or warranty of Purchaser
          contained in Section 6.1 or 6.2.1 of this Agreement (collectively,
          the "Purchaser Specified Claims"), (x) unless the aggregate of all
          Losses relating thereto for which Purchaser would, but for this
          proviso, be liable exceeds on a cumulative basis an amount equal to
          SEK 55 million, and then only to the extent of any such excess; and
          (y) for any individual breach where the Loss with respect to such
          individual breach is less than SEK 5 million, provided, that (i) the
          term "individual breach" shall mean each individual breach of a
          particular warranty and not the aggregation of individual breaches
          of a particular warranty into a single breach (e.g., if Purchaser
          failed to disclose five contracts under a particular warranty, and
          the failure to disclose any one of those contracts would be a
          breach, then the five contracts together would be considered
          multiple breaches, of which each such undisclosed contract would be
          an "individual breach"), and (ii) for purposes of the calculation of
          the Loss with respect to such individual breach, a series of
          separate Losses caused by or resulting from the same individual
          breach shall be aggregated (e.g., if an individual breach causes or
          results in two separate Losses of SEK 3 million each, such Losses
          shall be aggregated to a sum of SEK 6 million for purposes of
          determining whether the "Loss with respect to such individual
          breach" is less than SEK 5 million); and

               (ii)  under clause (a) of this Section 9.2 for any Losses in
          excess of an amount equal to 80% of the International Purchase
          Price; provided, however, that this limitation shall not apply to
          any Losses relating to a Purchaser Specified Claim.

9.3.      Termination of Indemnification

          The obligations to indemnify and hold harmless any party:

          (a)   pursuant to clause (a) of each of Sections 9.1 and 9.2, other
     than such obligations relating to the Insurance Agreement Claims, the ABB
     Specified Claims or the Purchaser Specified Claims, shall terminate on
     the second anniversary of the Closing Date; provided, however, that such
     obligations to indemnify and hold harmless shall not terminate with
     respect to any item as to which the Person to be indemnified


                                     -68-





     shall have, before the second anniversary of the Closing Date, provided
     notice with respect to a Third Party Claim or Direct Claim, as
     applicable;

          (b)   pursuant to clause (a) of Section 9.1 for obligations relating
     to the Insurance Agreement Claims shall terminate on the fifth
     anniversary of the Closing Date; provided, however, that such obligations
     to indemnify and hold harmless shall not terminate with respect to any
     item as to which the Person to be indemnified shall have, before the
     fifth anniversary of the Closing Date, provided notice with respect to a
     Third Party Claim or Direct Claim, as applicable; and

          (c)   pursuant to: (i) clause (a) of Sections 9.1 and 9.2 for ABB
     Specified Claims or Purchaser Specified Claims; (ii) pursuant to the
     clauses of Sections 9.1 and 9.2 other than clause (a); (iii) Section 9.8;
     (iv) Section 9.9; and (v) Section 9.10 shall not terminate with respect
     to any item as to which the Person to be indemnified shall have, before
     the expiration of the applicable statute of limitations, if any, provided
     notice with respect to a Third Party Claim or Direct Claim, as
     applicable.

9.4.      PROCEDURES RELATING TO THIRD PARTY AND DIRECT INDEMNIFICATION CLAIMS

9.4.1     Third Party Claims

          (a)   In order for a Person (the "Indemnified Party") to be entitled
     to any indemnification pursuant to this Article 9 in respect of, arising
     out of or involving a claim or demand (other than a claim or demand
     relating to Taxes) made by any Person other than a party hereto against
     the Indemnified Party (a "Third Party Claim"), such Indemnified Party
     must notify the Person obligated to provide indemnification pursuant to
     this Article 9 (the "Indemnifying Party") in writing of the Third Party
     Claim promptly, and in any event within thirty (30) days, after receipt
     by such Indemnified Party of written notice of the Third Party Claim;
     provided, however, that failure to give such notification shall not
     affect the indemnification provided under this Agreement except to the
     extent the Indemnifying Party shall have been actually and materially
     prejudiced as a result of such failure. Such written notice shall
     describe in reasonable detail the facts and circumstances known to the
     Indemnified Party with respect to the subject matter of such Third Party
     Claim. Thereafter, the Indemnified Party shall deliver to the
     Indemnifying Party promptly, and in any event within ten (10) Business
     Days after the Indemnified Party's receipt thereof, copies of all notices
     and documents (including court papers) received by the Indemnified Party
     relating to the Third Party Claim; provided, however, that failure to
     make such delivery shall not affect the indemnification provided under
     this Agreement except to the extent the Indemnifying Party shall have
     been actually and materially prejudiced as a result of such failure.

          (b)   If a Third Party Claim is made against an Indemnified Party, the
     Indemnifying Party shall be entitled to participate in the defense
     thereof and, if it so chooses and acknowledges its obligation to fully
     indemnify the Indemnified Party therefor in accordance with this
     Agreement, to assume and control the defense thereof with counsel
     selected by the Indemnifying Party, the selection of whom shall be
     subject to prior consultation and cooperation with the Indemnified Party
     for a period of no less than ten (10) days (but not the consent of the
     Indemnified Party) unless the Third Party Claim seeks an order or
     injunction or other relief requiring a response from the Indemnifying
     Party in less than ten (10) days, provided that the Indemnifying Party
     keeps the Indemnified Party and its attorneys reasonably informed as to
     the progress of the defense and any proposed settlement. If the
     Indemnifying Party so elects to assume the defense of a Third Party
     Claim, the


                                     -69-





     Indemnifying Party shall not be liable to the Indemnified Party for legal
     expenses subsequently incurred by the Indemnified Party in connection
     with the defense thereof. If the Indemnifying Party assumes such defense,
     the Indemnified Party shall have the right to participate in the defense
     thereof and to employ at its own expense counsel not reasonably objected
     to by the Indemnifying Party separate from the counsel employed by the
     Indemnifying Party, it being understood that the Indemnifying Party shall
     control such defense, subject to the remaining terms of this Section
     9.4.1.

          (c)   The Indemnifying Party shall be liable for the reasonable fees
     and expenses of one primary counsel, and to the extent reasonably
     required in connection with such Third Party Claim, one or more local
     counsel, and such other counsel as may be reasonably required due to a
     conflict of interest among Indemnified Parties, in each case employed by
     the Indemnified Party for any period during which the Indemnifying Party
     has not assumed the defense thereof.

          (d)   If the Indemnifying Party chooses to defend or prosecute any
     Third Party Claim, all the parties hereto shall reasonably cooperate and
     shall cause their Affiliates to reasonably cooperate in the defense or
     prosecution thereof. Such cooperation shall include the retention and
     (upon the Indemnifying Party's request) the provision to the Indemnifying
     Party of records and information that are reasonably relevant to such
     Third Party Claim, and making employees available on a mutually
     convenient basis to provide additional information and explanation of any
     material provided hereunder.

          (e)   Whether or not the Indemnifying Party assumes the defense of a
     Third Party Claim, the Indemnified Party shall not admit any liability
     with respect to, or settle, compromise or discharge, such Third Party
     Claim without the Indemnifying Party's prior written consent (which
     consent shall not be unreasonably withheld or delayed). If the
     Indemnifying Party assumes the defense of a Third Party Claim, the
     Indemnified Party shall agree to any settlement, compromise or discharge
     of such Third Party Claim that the Indemnifying Party may recommend and
     that by its terms (or pursuant to a binding commitment of the
     Indemnifying Party) obligates the Indemnifying Party to pay the full
     amount (subject to any limitation on payment contained in this Article 9)
     of such liability in connection with such Third Party Claim which
     releases the Indemnified Party completely in connection with such Third
     Party Claim.

          (f)   Notwithstanding anything to the contrary in this Section 9.4.1,
     the Indemnified Party may assume the exclusive right to defend any Third
     Party Claim (and the Indemnifying Party shall be liable for the
     reasonable fees and expenses of one primary counsel, and to the extent
     reasonably required in connection with such Third Party Claim, one or
     more local counsel, and such other counsel as may be reasonably required
     due to a conflict of interest among Indemnified Parties, incurred by the
     Indemnified Party in defending such Third Party Claim) if the Third Party
     Claim seeks an order, injunction or other equitable relief or relief for
     non-monetary damages against the Indemnified Party that cannot be
     separated from any related claim for money damages; provided that upon
     the non-appealable grant or dismissal of all such applications for an
     order, injunction or other equitable relief or relief for non-monetary
     damages, the Indemnifying Party may resume the exclusive right to defend
     such Third Party Claim. If all of such injunctive, equitable and other
     non-monetary relief portions of the Third Party Claim can be so separated
     from that for money damages, the Indemnifying Party shall be entitled to
     assume the defense of the portion relating to money damages. In the event
     the Indemnified Party assumes the exclusive right to defend any such
     Third Party Claim under this Section 9.4.1, the Indemnifying Party will
     not be bound by any


                                     -70-





     determination of such claim or proceeding so defended or any compromise
     or settlement effected without its consent (which may not be unreasonably
     withheld or delayed).

          (g) If the Indemnifying Party shall fail to defend any claim or
     proceeding for which it has assumed the defense hereunder, or if, after
     commencing or undertaking any such defense, the Indemnifying Party fails
     to diligently prosecute and defend or withdraws from such defense, then
     the Indemnified Party may notify the Indemnifying Party of this
     circumstance, and the Indemnifying Party shall have fifteen (15) days to
     rectify this failure. If such failure is not rectified within such
     period, then the Indemnified Party shall have the right to defend such
     Third Party Claim by giving the Indemnifying Party written notice of such
     decision within fifteen (15) days after the expiration of the fifteen-day
     cure period referred to in the previous sentence; provided, however, that
     the Indemnified Party shall not admit any liability or consent to the
     entry of any judgment or enter into any settlement without the prior
     written consent of the Indemnifying Party (which consent shall not be
     unreasonably withheld or delayed). If the Indemnified Party assumes the
     defense of a Third Party claim pursuant to this Section 9.4.1, the
     Indemnifying Party shall be entitled to (i) participate in the defense of
     such Third Party Claim, and (ii) employ counsel, at its own expense,
     separate from the counsel employed by Indemnified Party.

9.4.2     Direct Claims

          In the event any Indemnified Party should have an indemnification
claim against any Indemnifying Party under this Agreement that does not
involve a Third Party Claim being asserted against or sought to be collected
from such Indemnified Party (a "Direct Claim"), the Indemnified Party shall
promptly deliver notice of such Direct Claim to the Indemnifying Party, which
notice must refer to this Section 9.4.2 and expressly state that the
Indemnifying Party's failure to dispute any such Direct Claim within thirty
(30) days following the Indemnifying Party's receipt of such notice shall
result in such Direct Claim being conclusively deemed a liability of the
Indemnifying Party pursuant to this Section 9.4.2. The failure by any
Indemnified Party so to notify the Indemnifying Party shall not relieve the
Indemnifying Party from any liability that it may have to such Indemnified
Party, except to the extent that the Indemnifying Party has been actually and
materially prejudiced by such failure. If the Indemnifying Party does not
notify the Indemnified Party within thirty (30) days following its receipt of
such notice that the Indemnifying Party disputes such Direct Claim, such
Direct Claim specified by the Indemnified Party in such notice shall be
conclusively deemed a liability of the Indemnifying Party under this Article
9, and the Indemnifying Party shall pay the amount of such liability to the
Indemnified Party on demand, or in the case of any notice in which the amount
of the Direct Claim is estimated, on such later date when the amount of such
Direct Claim is finally determined; provided that in any such case such
payment shall be made in accordance with Section 9.7. If the Indemnifying
Party disputes its liability with respect to such Direct Claim in a timely
manner, the Indemnifying Party and the Indemnified Party shall proceed in good
faith to negotiate a resolution of such dispute; provided, however, that
either party may at any time refer such dispute to arbitration pursuant to
Section 11.10.

9.5.      Assignment of Rights

          Promptly upon request by the Indemnifying Party after having paid in
full the Indemnified Party for any Loss in accordance with this Article 9, the
Indemnified Party shall use reasonable efforts to assign, or cause to be
assigned, to the Indemnifying Party or its designated Affiliate any and all
rights (including any rights to indemnification and


                                     -71-





reimbursement) of the Indemnified Party and its Affiliates against any Person
(other than an Affiliate of the Indemnified Party) in relation to and to the
extent of the Loss so indemnified by the Indemnifying Party.

9.6.      Tax Indemnification and Related Matters

          Notwithstanding anything in this Agreement to the contrary:

9.6.1     Tax Indemnification

          (a)   ABB shall indemnify Purchaser and its Affiliates and each of
their respective officers, directors, employees, heirs, successors and assigns
against and hold them harmless on an after-Tax basis from (i) all liability
for Taxes of each Acquired Company (including Taxes resulting from any Tax
sharing, allocation, indemnification or similar agreement between any Acquired
Company and any other Person) and each affiliated group of which any Acquired
Company is or has been a member with respect to any taxable period ending on
or before the Measurement Date or with respect to the portion ending on the
Measurement Date of any taxable period that includes (but does not end on)
such date (each, a "Pre-Measurement Tax Period"), to the extent such Taxes are
not reflected in the Final Closing Financial Statements, (ii) all Taxes
imposed on the Acquired Companies, as a result of United States Treasury
Regulation Section 1.1502-6(a) (or a similar provision of state, local or
foreign law), (iii) any Taxes in the form of value added tax imposed by any
taxing authority in Switzerland upon any Acquired Company after the
Measurement Date in connection with the Acquired Group being an Affiliate of
the ABB Group prior to the Closing, (iv) all liability for Taxes of ABB, the
Acquired Group and all of their Affiliates arising (directly or indirectly) as
a result of any merger, consolidation or other restructuring described in
Schedule 11.6 prior to the Closing and, except as provided in Section 11.12.2,
all liability for Taxes of ABB, the Acquired Group and all of their Affiliates
arising (directly or indirectly) as a result of the ABB Distribution or the
sale by ABB of the International Shares (but not, for the avoidance of doubt,
the sale of the U.S. Shares), (v) any breach of any representation or warranty
contained in Section 5.13 or a similar provision of state, local or foreign
law, and (vi) all liability for reasonable legal fees and expenses for any
item attributable to any item in clauses (i) through (v).

          (b)   In the case of a Straddle Period: (i) real, personal and
intangible property Taxes ("Property Taxes") for the Pre-Measurement Tax
Period shall be equal to the amount of such Property Taxes for such entire
Straddle Period multiplied by a fraction, the numerator of which is the number
of days during the Straddle Period that are in the Pre-Measurement Tax Period
and the denominator of which is the number of days in the Straddle Period; and
(ii) all other Taxes for the Pre-Measurement Tax Period shall be determined
based on an actual closing of the books as if such taxable period ended as of
the close of business on the Measurement Date and, in the case of any Taxes
attributable to the ownership of any equity interest in any partnership or
other "flow through" entity, based on an actual closing of the books as if the
taxable period of such partnership or other "flow through" entity ended as of
the close of business on the Measurement Date.

9.6.2     Tax Indemnity Payments

          (a)   Any Tax indemnity payment to be made hereunder shall be paid in
accordance with Section 9.7 and within ten (10) days after the Indemnified
Party makes written demand upon the Indemnifying Party, but in no case earlier
than five (5) Business


                                     -72-





Days prior to the date on which the relevant Taxes are required to be paid to
the relevant taxing authority (including as estimated Tax payments).

          (b)   For the avoidance of doubt, all indemnity payments under this
Section 9.6 shall be made on a one-for-one basis, without regard to any caps,
floors, baskets or other similar limitations.

9.6.3     Tax Claims

          (a)   If a claim shall be made by any taxing authority, which, if
successful, might result in an indemnity payment to the Indemnified Party
pursuant to this Section 9.6, the Indemnified Party shall notify in writing
the Indemnifying Party reasonably promptly of such claim (a "Tax Claim");
provided, however, that the failure to give such prompt written notice shall
not affect the indemnification provided hereunder except to the extent the
Indemnifying Party has actually and materially been prejudiced as a result of
such failure.

          (b)   With respect to any Tax Claim relating to Taxes with respect to
any taxable period ending on or before the Measurement Date, ABB shall control
all proceedings and may make all decisions in connection with such Tax Claim,
including initiating any claim for refund, amending any Tax Return and
contesting, resolving and defending against any assessment for additional
Taxes, notice of Tax deficiency or other adjustment of Taxes, provided that
Purchaser, and counsel of Purchaser's own choosing, shall have the right to
comment on all aspects of the prosecution or defense of such Tax Claim that
could affect the Taxes of Purchaser or any Acquired Company after the
Measurement Date, and provided further that ABB shall not settle any Tax Claim
that could affect the Taxes of Purchaser or any Acquired Company after the
Measurement Date without the prior written consent of Purchaser (which consent
shall not be unreasonably withheld or delayed). Except as provided in the
preceding sentence, Purchaser shall control all proceedings with respect to
all other Tax Claims and may make all decisions in connection with such Tax
Claims; provided, however, that Purchaser or any Affiliate or representative
thereof shall not settle any Tax Claim that could affect the Tax liability of
ABB or any Affiliate thereof before the Measurement Date without prior written
consent of ABB (which consent shall not be unreasonably withheld or delayed).

9.6.4     Tax Refunds

          (a)   Except as provided in Section 9.6.4(b), the amount or economic
benefit of any refunds, credits or offsets of Taxes (including any interest in
respect thereof) of any Acquired Company (including any foreign tax credits
for taxes incurred during any Pre-Measurement Tax Period) for any
Pre-Measurement Tax Period, to the extent not reflected in the Final Closing
Financial Statements, shall be for the account of ABB. Notwithstanding the
foregoing and provided that Sirius America cannot elect to waive a carryback
without causing its U.S. Affiliates to also waive a carryback, any such
refunds, credits or offsets of income Taxes shall be for the account of
Purchaser to the extent that such refunds, credits or offsets of income Taxes
are attributable (determined on a marginal basis) to the carryback from a
taxable period beginning after the Measurement Date (or the portion of a
Straddle Period that begins on the day after the Measurement Date) of items of
loss, deductions, or other Tax items, of any Acquired Company (or any of their
respective Affiliates, including Purchaser). The amount or economic benefit of
any refunds, credits or offsets of Taxes of any Acquired Company for any
taxable period beginning after the Measurement Date shall be for the account
of Purchaser. The amount or economic benefit of any refunds, credits or


                                     -73-





offsets of Taxes of any Acquired Company for any Straddle Period shall be
equitably apportioned between ABB and Purchaser; provided, however, that any
refunds, credits or offsets of Taxes (including any interest in respect
thereof) reflected in the Closing Financial Statements shall be excluded from
any such apportionment.

          (b)   Notwithstanding anything to the contrary, the amount or economic
benefit of any refunds, credits or offsets of Taxes (including any interest in
respect thereof) attributable to or resulting from Tax repayments claimed by
Sirius Belgium with respect to reassessments of Taxes with the Belgian tax
authorities for any Pre-Measurement Tax Period (the "Belgian Tax
Reassessments") shall be for the account of ABB. ABB and Purchaser agree that
ABB shall prepare and file all amended Tax Returns with respect to the Belgian
Tax Reassessments and shall control any Tax Claim arising therefrom. Purchaser
shall cooperate, so long as such cooperation in Purchaser's good faith and
reasonable judgment can be made without undue burden or expense or disruption
to the operations of the Business, with ABB's reasonable requests for
information held by an Acquired Company in order to enable ABB to prepare the
Tax Returns with respect to the Belgian Tax Reassessments. Purchaser shall be
under no obligation to utilize any refunds, credits or offsets of Taxes
attributable to or resulting from the liquidation of Sirius Belgium. If
Purchaser, in its sole discretion, determines that, after first taking into
account all other items of income, gain, loss, deduction, credit or reserve
(including safety reserve) that are available for the relevant taxable period
or periods, Sirius International or any affiliate or successor thereto
actually utilized any credits or offsets resulting from the liquidation of
Sirius Belgium and either (i) such utilization actually reduces the amount of
Taxes that Sirius International or any affiliate or successor thereto
otherwise would have been required to pay to a taxing authority had it not
utilized such credits or offsets or (ii) Sirius International or any affiliate
or successor thereto receives a refund or credit against its Taxes from a
taxing authority that it would not otherwise have received had it not utilized
such credits or offsets, then the amount of such reduction of Taxes paid or
the amount of such refund or credit shall be 80 percent for the account of ABB
and 20 percent for the account of Purchaser; provided, however, that ABB
agrees to repay to Purchaser its 80 percent portion of the amount of such
reduction or the amount of such refund or credit (plus any penalties, interest
or other charges imposed by a taxing authority) in the event that (x) it is
determined by a taxing authority that Sirius International was not entitled to
such reduction of Taxes paid or (y) Sirius International or any affiliate or
successor thereto is required to repay such refund to a taxing authority. ABB
and Purchaser agree that (i) ABB will provide reasonable instructions in the
preparation and filing of all Tax Returns that relate to the liquidation of
Sirius Belgium and (ii) all expenses relating to the liquidation of Sirius
Belgium and the preparation of such Tax Returns shall be borne solely by ABB.
For the avoidance of doubt, the amount or economic benefit of any refunds,
credits or offsets of Taxes attributable to or resulting from the Belgian Tax
Reassessments or the liquidation of Sirius Belgium shall not in any way
increase Net Equity.

          (c)   Each party shall forward, and shall cause its Affiliates to
forward, to the party entitled pursuant to this Section 9.6.4 to receive the
amount or economic benefit of a refund, credit or offset to Tax the amount of
such refund, or the economic benefit of such credit or offset to Tax, within
10 days after such refund is received or after such credit or offset is
allowed or applied against another Tax liability, as the case may be.


                                    - 74 -






9.6.5     Amended Tax Returns

          None of Purchaser and the Acquired Group and any Affiliate thereof
shall file any amended Tax Returns with respect to any Pre-Measurement Tax
Period without prior written consent of ABB (which consent shall not be
unreasonably withheld or delayed).

9.6.6     Termination of Tax Indemnification

          The representations and warranties contained in Section 5.13 shall
terminate upon the expiration of the applicable statute of limitations period.
The obligations to indemnify and hold harmless a party hereto pursuant to this
Section 9.6 shall terminate at the time the applicable statutes of limitations
with respect to the Tax liabilities in question expire (giving effect to any
extension thereof); provided, however, that such obligations to indemnify and
hold harmless shall not terminate with respect to any Tax as to which the
Indemnified Party shall have, before the expiration of the statute of
limitations, previously made a claim by delivering a notice of such claim
(stating in reasonable detail the basis of such claim) to the Indemnifying
Party.

9.7.      Indemnity Payments

          Any indemnity payment hereunder (i) shall be made to Purchaser or
ABB, as the case may be, by wire transfer to an account specified by the
Indemnified Party in Swedish kronor in immediately available funds together
with interest thereon from the date of delivery of notice of the Third Party
Claim or Direct Claim, as applicable, by any Indemnified Party to the date of
payment at an annual rate of 3% (such interest shall be calculated on the
basis of a year of 365 days and the actual number of days elapsed), compounded
annually and (ii) shall be treated as an adjustment to the International
Purchase Price for all Tax purposes to the extent permitted by Law.

9.8.      Scandinavian Re Indemnity

9.8.1     Indemnity by ABB

          (a)   After the Closing and subject to clause (c) below, ABB agrees
to indemnify Purchaser and its Affiliates (including, for the avoidance of
doubt, the Acquired Companies) and each of their respective officers, directors,
employees, heirs, successors and assigns against, and hold them harmless from,
eighty percent (80%) of all Losses In Excess Of Reserves (as defined below)
incurred by any of them arising out of or relating to the following disputes
involving Scandinavian Re (the "Scan Re Disputes"):

               (i)   the BCS Insurance/NAWS dispute identified as item 180 in
          the Scandinavian Re Running Reserve Memo dated July 22, 2003 (the
          "Scan Re Memo");

               (ii)  the BIG/Superior National dispute identified as Treaty
          201, all underwriting years, in the Scandinavian Re Memo;

               (iii) the Gerling dispute identified as Treaty 193, all
          underwriting years, in the Scan Re Memo; and

               (iv)  the Verzekerd dispute identified as Treaty 176, all
          underwriting years, in the Scan Re Memo.


                                    - 75 -





          (b)   The term "Losses In Excess Of Reserves" means all Losses
incurred by Purchaser and any of its Affiliates (including the Acquired Group)
with respect to any Scan Re Dispute after the Measurement Date which are in
excess of any net loss Reserves and any net payables/receivables which are
specifically set forth in the balance sheet included in the Final Closing
Financial Statements with respect to the applicable Scan Re Dispute.

          (c)   Notwithstanding the fact that, pursuant to clause (a) above,
Purchaser shall be liable for twenty percent (20%) of all Losses In Excess Of
Reserves, if the aggregate liability of Purchaser and its Affiliates and each
of their respective officers, directors, employees, heirs, successors and
assigns for such twenty percent (20%) of Losses In Excess Of Reserves should
exceed $4,000,000, then ABB agrees to indemnify Purchaser and its Affiliates
and each of their respective officers, directors, employees, heirs, successors
and assigns for the portion of all amounts in excess of such $4,000,000.

9.8.2     Payments by Purchaser

          (a)   After the Closing, Purchaser agrees that it shall pay to ABB
eighty percent (80%) of all Gains (as defined below) obtained or otherwise
recognized by Purchaser or any of its Affiliates (including the Acquired
Group). Such payment shall be made to ABB or, at ABB's discretion, one of its
Affiliates, in Swedish kronor, by electronic transfer in immediately available
funds and to the account designated by ABB, within five (5) Business Days
after such Gain has been obtained. A Gain shall be deemed to have been
"obtained" by Purchaser or its Affiliates at the time that a final,
non-appealable and binding settlement or resolution of a Scan Re Dispute has
been paid.

          (b)   A "Gain" means the difference (assuming a positive number)
between: (i) the total amount of any net loss Reserves and any net
payables/receivables which have been established in the Final Closing
Financial Statements with respect to any Scan Re Dispute; and (ii) the amount
of Losses, if any, actually incurred or recognized by Scandinavian Re after
the Measurement Date under any final, non-appealable and binding settlement or
resolution of such Scan Re Dispute. For the avoidance of doubt, in no case
shall the Gain with respect to any Scan Re Dispute be greater than the total
amount of any net loss Reserves and any net payables/receivables which have
been established in the Final Closing Financial Statements with respect to
such Scan Re Dispute.

9.8.3     Prosecution and Settlement of Scan Re Disputes

          (a)   Notwithstanding anything to the contrary contained in this
Agreement, ABB shall have the right, in its sole and absolute discretion, to
settle or compromise any of the Scan Re Disputes prior to the Measurement
Date; provided, however, that ABB shall not enter into any such settlement
that imposes any injunctive or similar equitable obligations on any Acquired
Company without the prior written consent of Purchaser (which consent shall
not be unreasonably withheld or delayed).

          (b)   After the Measurement Date and up to the Closing Date, ABB
shall not settle or compromise any of the Scan Re Disputes without the prior
written consent of Purchaser (which consent shall not be unreasonably withheld
or delayed).

          (c)   After the Closing Date, the provisions of Section 9.4 shall
apply, mutatis mutandis, in connection with the defense and prosecution of any
remaining Scan Re Disputes; provided, however, that (i) Purchaser shall have
the sole right to control the defense


                                    - 76 -





and prosecution of any remaining Scan Re Disputes and ABB shall not be able to
assume the defense or prosecution of any such Scan Re Dispute and (ii)
Purchaser's obligation to obtain ABB's consent (which shall not be
unreasonably withheld or delayed) prior to settling, compromising, or
discharging any Scan Re Dispute shall be conditional on ABB's diligent review
on an ongoing basis of the facts and law with respect to such Scan Re Dispute
and ABB's employment (at ABB's sole expense) of counsel qualified in insurance
and reinsurance litigation to review facts and law with respect to such Scan
Re Dispute on behalf of ABB (the selection of which counsel shall be subject
to the prior consultation and cooperation with Purchaser (but not the consent
of Purchaser)) for a period of no less than ten (10) days unless the proposed
settlement, comprise or discharge of such Scan Re Dispute requires a response
from ABB in less than ten (10) days. Notwithstanding any other provision of
this Agreement, if Purchaser does not accept any settlement, compromise or
discharge of any Scan Re Dispute due to ABB withholding its consent with
respect to such settlement, compromise or discharge, ABB shall indemnify
Purchaser for 100% of any Losses resulting from the applicable Scan Re Dispute
that are in excess of the Losses that would have resulted from such Scan Re
Dispute had such settlement, compromise or discharge been accepted.

9.9.      Special Indemnity in Respect of Alstom Instruments

          (a)   After the Closing, ABB agrees to indemnify Purchaser and its
Affiliates (including, for the avoidance of doubt, the Acquired Companies) and
each of their respective officers, directors, employees, heirs, successors and
assigns (the "Alstom Indemnified Parties") against, and hold them harmless
from, all Losses (the "Alstom Losses") arising out of or relating to each
Alstom Instrument listed or required to be listed in Section 5.22 of the
Disclosure Schedule, other than Losses resulting from any action taken by the
Alstom Indemnified Parties to transfer their obligations under such Alstom
Instrument to any Person other than an Affiliate.

          (b)   Notwithstanding clause (a) above, ABB shall have no obligation
to indemnify Purchaser and its officers, directors, employees, heirs,
successors and assigns against, and hold them harmless from, any Alstom Losses
unless Purchaser and its Affiliates shall have exhausted all remedies
available to them (including prosecuting an action or otherwise litigating),
whether in law and/or equity, to prevent such Alstom Losses from arising or to
recover such Alstom Losses from the Alstom Group; provided, however, that if
any member of the Alstom Group should become the subject of a rehabilitation,
liquidation, conservatorship, receivership, bankruptcy, proceeding for relief
or composition of debts or similar proceeding and such proceeding shall not
have been terminated within sixty (60) days from commencement, Purchaser and
its Affiliates shall be deemed to have exhausted all remedies available to
them if Purchaser or any of its Affiliates files a claim with respect to the
Alstom Instrument in connection with such proceeding.

9.10.     Special Indemnity in Respect of ABB Instruments

          After the Closing, ABB agrees to indemnify Purchaser and its
Affiliates (including, for the avoidance of doubt, the Acquired Companies) and
each of their respective officers, directors, employees, heirs, successors and
assigns against, and hold them harmless from, all Losses arising out of or
relating to each ABB Instrument listed or required to be listed in Section
5.23 of the Disclosure Schedule.


                                    - 77 -





9.11.     Other Limitations; Indemnity Provisions

9.11.1    Losses Accounted for in Final Closing Financial Statements

          ABB's liability hereunder for Losses shall be reduced to the extent
of the amount of (i) any specific provision or reserve in respect of the
relevant Losses established in the Final Closing Financial Statements and (ii)
any general or bulk reserve pool in the Final Closing Financial Statements
that ABB demonstrates was established in respect of the relevant Losses.

9.11.2    Insurance Proceeds

          The amounts which, but for this Section 9.11.2, would be recoverable
under this Agreement, shall be reduced when and to the extent any insurance
proceeds are recovered in respect thereof by the Indemnified Party or any of
its Affiliates under any policy of insurance carried by any of them (net of
all reasonable out-of-pocket expenses incurred in obtaining such recovery and
net of any increase in the relevant insurance premium directly attributable to
such recovery as verified in writing by the relevant insurance carrier at the
time of recovery).

9.11.3    Subsequent Recovery

          If the Indemnifying Party pays an amount in discharge of any claim
under this Agreement and the Indemnified Party or any of its Affiliates
subsequently recovers from a third Person a sum which is attributable to the
subject matter of the claim, the Indemnified Party shall promptly pay to the
Indemnifying Party an amount equal to all amounts recovered up to the
aggregate amount thus paid by the Indemnifying Party hereunder.

9.11.4    Claims Satisfied Under Other Provisions

          For the avoidance of doubt, it is understood and agreed that to the
extent that a claim with respect to a Loss has been satisfied under a
provision of this Agreement, a claim for indemnification or reimbursement for
such Loss may not be made under any other provision of this Agreement.

9.11.5    Tax Savings

          The amounts which, but for this Section 9.11.5, would be recoverable
under this Article 9 from an Indemnifying Party shall be (i) increased by any
net Tax cost incurred by the Indemnified Party or any of its Affiliates
arising from receipt of indemnity payments hereunder and (ii) reduced by any
net Tax benefits arising from the incurrence or payment of any Loss. In
computing the amount of any such Tax cost or Tax benefit, the Indemnified
Party shall be deemed to recognize all other items of income, gain, loss,
deduction or credit before recognizing any item arising from the receipt of
any indemnified Loss. Any indemnification payment hereunder shall initially be
calculated without regard to this Section 9.11.5 and shall be increased or
reduced to reflect any such net Tax cost or net Tax benefit only after the
Indemnified Party has actually realized such cost or benefit. For purposes of
this Agreement, an Indemnified Party shall be deemed to have "actually
realized" a net Tax cost or a net Tax benefit when and to the extent that the
amount of Taxes payable by such Indemnified Party is increased above or
reduced below, as the case may be, the amount of Taxes that such Indemnified
Party would be required to pay but for the receipt of the


                                    - 78 -





indemnity payment or the incurrence or payment of such Loss. If a Tax benefit
arising from the incurrence or payment of a Loss is actually realized prior to
the fifth anniversary of the date of the related payment or payments made by
ABB under this Article 9 in respect of such Loss ("Prior ABB Payments"),
Purchaser shall pay to ABB the amount of such Tax benefit (up to the amount of
the Prior ABB Payments) no later than 15 days after such Tax benefit is
actually realized, and any excess of such Tax benefit over the Prior ABB
Payments shall be applied to reduce any future payments to be made by ABB
pursuant to Article 9; provided that if Purchaser is required to refund any
part of such Tax benefit to any taxing authority for which ABB received the
benefit prior to the fifth anniversary of the related payment made under this
Article 9, ABB shall reimburse Purchaser for the amount of such refund.

9.11.6    Mitigation

          Neither party shall have liability hereunder for Losses from a
breach of any of its representations, warranties or covenants to the extent
that such Losses would not have arisen but for a failure by the other party or
any of its Affiliates, upon becoming aware of such breach, to use reasonable
efforts to mitigate the Losses resulting from such breach.

9.11.7    Changes in Laws

          An Indemnifying Party shall have no liability hereunder to the
extent that any alteration or repeal or enactment of any applicable Law after
the Closing Date increases the Losses resulting from a failure of any of its
representations or warranties in Article 5 or Article 6.

9.11.8    Right to Cure

          Each party agrees that it will promptly inform the other party of
any breach of representation, warranty or covenant in this Agreement by such
other party which may lead to a Direct Claim or a Third Party Claim upon
becoming aware of such breach, so that the other party may commence remedial
action; provided, however, that this Section 9.11.8 shall not in any way
affect either party's right to indemnification under this Article 9.

9.11.9    Exclusive Remedy

          Each party acknowledges and agrees that its sole and exclusive
remedy with respect to any and all claims relating to the subject matter of
this Agreement made after the Closing shall be pursuant to the indemnification
and other provisions set forth in this Article 9, or elsewhere in this
Agreement, and hereby waives, to the fullest extent permitted under applicable
Law, any and all rights, claims, causes of action and remedies (including but
not limited to any right to rescind this Agreement) it may have against the
other party under applicable Law in connection with the transactions
contemplated hereby (other than claims for fraud). Nothing in this Section
9.11.9 shall limit the right, if any, of such party to (i) obtain specific
performance of this Agreement in the event of the other party's breach of its
obligations hereunder or (ii) pursue its rights under common law prior to the
Closing with respect to claims relating to the subject matter of this
Agreement.


                                    - 79 -





9.12.     Survival of Representations and Warranties and Covenants

          Except as otherwise expressly stated in this Agreement, the
representations, warranties, covenants and agreements of each party contained
in this Agreement shall survive the Closing indefinitely.

9.13.     Reliance On Representations and Warranties

          Each party acknowledges for purposes of any claim by it with respect
to this Agreement that it has not relied on any representations or warranties
of the other party in connection with the transactions contemplated hereby
other than those expressly made in this Agreement or any certificate delivered
by or on behalf of the other party at the Closing; provided that this Section
9.13 shall not prejudice any rights Purchaser may have in connection with
claims for fraud under applicable Law in connection with the transactions
contemplated hereby.

9.14.     ABB's Disclosure

          Each representation or warranty given by ABB in Article 5 is
qualified by any matter which is fairly disclosed in or pursuant to the
Disclosure Schedule (but only to the extent that such disclosure specifically
refers to the Section of this Agreement containing such representation or
warranty) and any matter expressly provided for under the terms of this
Agreement. Certain information set forth in the Disclosure Schedule or other
Schedules is included for informational purposes and may not be required to be
disclosed pursuant to this Agreement. The disclosure of any information shall
not be deemed to constitute an acknowledgement that such information is
required to be disclosed in connection with the representations and warranties
made by ABB in this Agreement or that it is material, nor shall such
information be deemed to establish a standard of materiality.

Agreement may be terminated and the transactions contemplated hereby abandoned
at any time prior to the Closing:

          (a)   by the written consent of ABB and Purchaser;

          (b)   by either ABB or Purchaser, if the Closing shall not have been
     consummated by July 31, 2004; provided, however, that the right to
     terminate this Agreement under this clause (b) shall not be available to
     a party whose failure to fulfill any obligation under this Agreement has
     been the cause of, or resulted in, the failure of the Closing to occur on
     or before such date;

          (c)   by ABB, if Purchaser in any material respect shall have
     breached or failed to perform or comply with any of its representations,
     warranties, covenants or


                                    - 80 -





     other agreements contained in this Agreement, which breach or failure to
     perform or comply: (i) would give rise to the failure of a condition set
     forth in Section 8.3; and (ii) has not been, or is incapable of being,
     cured by Purchaser within 30 days of Purchaser's receipt of written
     notice thereof from ABB;

          (d)   by Purchaser, if ABB in any material respect shall have
     breached or failed to perform or comply with any of its representations,
     warranties, covenants or other agreements contained in this Agreement,
     which breach or failure to perform or comply: (i) would give rise to the
     failure of a condition set forth in Section 8.2; and (ii) has not been,
     or is incapable of being, cured by ABB within 30 days of ABB's receipt of
     written notice thereof from Purchaser;

          (e)   by Purchaser, if there has occurred any change in, or effect
     on, the Acquired Group which (i) would give rise to the failure of the
     condition set forth in Section 8.2(f); and (ii) has not been, or is
     incapable of being, cured by ABB within 30 days of ABB's receipt of
     written notice thereof from Purchaser;

          (f)   by Purchaser, if any proceeding is instituted by ABB (or any
     parent company of ABB), or ABB (or such parent company) publicly
     announces an intention to institute such a proceeding, to adjudicate any
     of them bankrupt or insolvent, or seeking liquidation, winding up or
     reorganization arrangements, or adjustment, protection, relief or
     composition of its debts under any Law relating to bankruptcy, insolvency
     or reorganization (but excluding, for the avoidance of doubt, the merger
     contemplated by Schedule 11.6 of this Agreement); and

          (g)   by ABB, if any proceeding is instituted by Purchaser (or any
     parent company of Purchaser), or Purchaser (or such parent company)
     publicly announces an intention to institute such a proceeding, to
     adjudicate any of them bankrupt or insolvent, or seeking liquidation,

10.1.3    Effects of Termination

          If this Agreement is terminated and the transactions contemplated
hereby are abandoned as described in this Section 10.1, this Agreement shall
become null and void and of no further force and effect, except for the
provisions of this Agreement relating to expenses (including but not limited
to Section 11.12), this Section 10.1, and Articles 9 and 11. Nothing in this
Section 10.1 shall be deemed to release either party from any liability for
any breach by such party of the terms and provisions of this Agreement prior
to termination.

10.1.4    Return or Destruction of Documents

          If this Agreement is terminated and the transactions contemplated
hereby are abandoned as described in this Section 10.1, Purchaser shall

transactions, whether so obtained before or after the execution hereof; and
(ii) all written information received by Purchaser with respect to the
Business and the other operations of ABB and/or its Affiliates (in each case

representatives.

10.2.2    Waivers

          No delay or failure on the part of any party to exercise any right,

                              GENERAL PROVISIONS

other party (such approval not to be unreasonably withheld or delayed); (ii)
except disclosure made in connection with an offering of notes, debentures,
equity or other securities by either party or any of its Affiliates and deemed

the tax structure of the transactions contemplated by this Agreement; and (ii)
this provision shall not permit disclosure to the extent that nondisclosure is
reasonably necessary in order to comply with applicable securities Laws.
Nothing in this Agreement shall in any way limit any party's ability to
consult any tax advisor (including a tax advisor independent from all other

regarding the U.S. federal, state and local income tax treatment or U.S.
federal, state and local income tax structure of the transactions contemplated
by this Agreement.

          Unless otherwise expressly provided in this Agreement, whenever the
parties are required to cooperate for any particular purpose hereunder,

11.4.     Severability

          If at any time any provision of this Agreement is or becomes
invalid, illegal or unenforceable under the laws of the State of New York, the
validity, legality and enforceability of the remainder of this Agreement shall
not be affected. In the event any provision is held in any proceeding pursuant
to Section 11.9 or 11.10 to be invalid, illegal or unenforceable, the parties
shall replace that provision with a new provision permitted by the laws of the
State of New York and having an economic effect as close as possible to the
deficient provision.

11.5.     No Third Party Beneficiaries

          Except for the provisions of this Agreement relating to Indemnified
Parties, this Agreement shall be directed and interpreted to the advantage of
the parties only and their permitted assignees, and no third Person shall
obtain any rights by virtue hereof.

11.6.     Assignment

          Neither party may assign its rights or obligations under this
Agreement to any third Person without the prior written consent of the other
party; provided, however, that such consent shall not be unreasonably withheld
or delayed in relation to assignment of rights if the assignment is to an
Affiliate of such party. The parties agree that the merger under applicable
Law of either party with any of its Affiliates as described in Schedule 11.6
pursuant to which the obligations under this Agreement vest in the surviving
party shall not constitute an assignment within this Section 11.6.

11.7.     Notices

11.8.     Governing Law

          This Agreement shall be governed by, and construed in accordance
with, the laws of the State of New York, regardless of the laws that might
otherwise govern under applicable principles of conflicts of laws thereof.

11.9.     Pre-closing Dispute Resolution

11.9.1    Jurisdiction; Service of Process

          Any action or proceeding initiated prior to the Closing and arising
out of or relating to this Agreement or any transaction contemplated hereby
shall be brought in the United States District Court for the Southern District
of New York, or, if a party cannot acquire jurisdiction in such federal court,
shall be brought in the courts of the State of New York, County of New York,
Borough of Manhattan (and the parties shall seek to have the matter tried by
the Special Commercial Part of the New York Supreme Court), and each of the
parties irrevocably submits to the exclusive jurisdiction of each such court
in any such action or proceeding, waives any objection it may now or hereafter
have to venue or to convenience of forum, agrees that all claims in respect of
the action or proceeding shall be heard and determined only in any such court
and agrees not to bring any action or proceeding arising out of or relating to
this Agreement or any transaction contemplated hereby in any other court;
provided, however, that any such action or proceeding which remains
outstanding at the Closing shall be withdrawn from such court on or prior to
the Closing Date and submitted to arbitration pursuant to Section 11.10.1
without prejudicing in any way any claim of either party thereto. For the
avoidance of doubt, any action or proceeding brought under this Section 11.9.1
for which a judgment has been rendered shall not be deemed an outstanding
action or proceeding at the Closing and neither party may submit such judgment
to arbitration under Section 11.10.1 after the Closing or otherwise appeal or
seek to review such judgment. The parties agree that any or all of them may
file a copy of this paragraph with any court as written evidence of the
knowing, voluntary and bargained agreement among the parties irrevocably to
waive any objections to venue or to convenience of forum. Process in any
action or proceeding referred to in the first sentence of this Section may be
served on any party anywhere in the world.


                                    - 85 -





11.9.2    Waiver of Jury Trial

          Each party hereby waives, to the fullest extent permitted by
applicable Law, any right it may have to a trial by jury in respect of any
action or proceeding initiated prior to the Closing and arising out of or
relating to this Agreement or any transaction contemplated hereby. Each party
(i) certifies that no representative, agent or attorney of any other party has
represented, expressly or otherwise, that such party would not, in the event
of any action, suit or proceeding, seek to enforce the foregoing waiver and
(ii) acknowledges that it and the other parties have been induced to enter
into this Agreement, by, among other things, the mutual waiver and
certifications in this Section 11.9.

11.10.    Post-closing Dispute Resolution

11.10.1   Arbitration

          Subject to the last sentence of this Section 11.10.1, any action or
proceeding initiated after the Closing and out of or relating to this
Agreement or any transaction contemplated hereby shall be determined, at the
request of either party, by arbitration in the English language conducted in
London, England, in accordance with the then-existing International
Arbitration Rules of the American Arbitration Association (the "Rules"). The
arbitration shall be conducted by three (3) arbitrators, of which each party
shall appoint one (1) arbitrator and the two (2) arbitrators thus appointed
shall appoint the presiding arbitrator (the "Chairman"). The Chairman shall
(i) be admitted to practice as an attorney and counselor at law in the State
of New York; (ii) be a partner or of counsel or retired partner or retired of
counsel at a prominent United States-based law firm; and (iii) have expertise
in mergers and acquisitions and international arbitration. The arbitrators
shall permit the parties to adduce expert testimony in connection with any
action or proceeding under this Section 11.10.1 and shall consider such expert
testimony in rendering their awards. The arbitrators shall give reasonably
detailed justifications for their awards in any proceeding and any judgment or
award rendered by the arbitrator shall be final, binding and unappealable and
may be entered by any court having jurisdiction thereof. The parties hereby
agree to the institution of any available "fast track" or other mechanisms or
procedures that would have the effect of streamlining or increasing the speed
of the arbitration. Subject to the last sentence of this Section 11.10.1, any
controversy concerning whether a dispute is an arbitrable dispute, whether
arbitration has been waived, whether an assignee of this Agreement is bound to
arbitrate, or as to the interpretation or enforceability of this paragraph
shall be determined by the arbitrators. In their award, the arbitrators shall
allocate, in their discretion, among the parties to the arbitration, all costs
of the arbitration, including the fees and expenses of the arbitration
proceedings and reasonable attorneys' fees, costs and expert witness expenses
of the parties. The parties hereto agree to comply with any award made in any
such arbitration proceedings that has become final in accordance with the
Rules and agree to the entry of a judgment in any jurisdiction upon any award
rendered in such proceedings becoming final under the Rules. The arbitrators
shall be entitled, if appropriate, to award any remedy in such proceedings,
including monetary damages, specific performance and all other forms of legal
and equitable relief, including punitive damages (to the extent not prohibited
by this Agreement). The provisions of this Section 11.10.1 shall not apply to
the matters provided for in Section 3.4 of this Agreement.

payable by Purchaser or any of its Affiliates to ABB or any of its Affiliates
or by ABB or any of its Affiliates to Purchaser or any of its Affiliates,
pursuant to this Agreement be set off against each other.

11.13.2   Exceptions

          Each party hereto may set off a sum equal to the amount of all
claims it may have against the other party hereto pursuant to this Agreement,
provided such claims have either been agreed by such other party or been
finally determined to be due in accordance with the provisions of Section 3.4
or finally adjudged by the arbitrators pursuant to Section 11.9, against
amounts payable by such first party to such other party pursuant to this
Agreement.

11.14.    Further Assurances

          After the Closing Date, the parties shall execute such other
documents or take, or cause to be taken, such other actions to the extent they
have not been accomplished on or by the Closing Date, as may be required to
transfer the U.S. Shares to U.S. Purchaser or to transfer the International
Shares to Purchaser in accordance with the terms and conditions of this
Agreement.
