                          thereof as follows: FIRST, to the next installment
                          thereof due after the date of such prepayment, and,

                          in accordance with the then outstanding amounts
                          thereof and may not be reborrowed. Notwithstanding the

                          stock of any foreign subsidiaries will be required to
                          be pledged. The Exchange Notes, if issued, shall, at

S.A., a Luxembourg corporation, CGU Holdings LLC, a Delaware limited liability
company, Seller and White Mountains, as amended by Amendment No.1 to the Stock
Purchase Agreement, dated as of October 15, 2000 and by Amendment No.2 to the

AGREEMENT"). The Acquisition will be accomplished through the acquisition by the
Borrower from the Seller of 100% of the equity interests of CGU Corporation, a
Delaware corporation ("CGU").

       Prior to or concurrently with the Acquisition, the following transactions
(the "PRE-CLOSING TRANSACTIONS") will occur:

            (i) White Mountains will contribute to the Parent, which will in
       turn contribute to Acquisition Co., all of the outstanding shares of
       Folksamerica Holding Company, Inc., a New York company ("FOLKSAMERICA"),
       and White Mountains' interests in certain other insurance assets
       (collectively with Folksamerica, the "PARENT INSURANCE ASSETS");

            (ii) CGU will exchange and/or contribute all of the shares of
       Commercial Union Insurance Company, a Massachusetts company, The Northern
       Assurance Company of America, a Massachusetts company, The Employers'
       Fire Insurance Company, a Massachusetts company, American Employers'
       Insurance Company, a Massachusetts company and Potomac Insurance Company
       of Illinois, an Illinois company, which are all first-tier subsidiaries
       of CGU, for (x) all of the shares of Pilot Insurance Company, a Canadian
       company ("PILOT"), a second-tier subsidiary of CGU, and (y) cash (the
       combined value of shares and cash to total an amount consistent with the
       Sources and Uses Table) (the Pilot shares are currently held by CGU
       Insurance Company, a Pennsylvania company ("CGUIC"), CGU Insurance
       Company of New Jersey, a New Jersey company ("CGUIC-NJ"), and General
       Accident Insurance Company, a Pennsylvania company ("GAIC"));

            (iii) Acquisition Co. will transfer all of the Parent Insurance
       Assets to CGUIC;

            (iv) CGU will sell all of the shares of Pilot to the Seller or an
       affiliate of Seller for cash;

            (v) CGU Asset Management, Inc., a Delaware corporation and a
       subsidiary of CGU, will sell all of the outstanding shares of CGU
       Investment Management Canada Limited, a Canadian company, to a subsidiary
       of the Seller;





            (vi) CGU will sell all of the outstanding shares of CGU Annuity
       Service Corporation, a Delaware corporation, and CGU Life Insurance
       Company of America, a Delaware corporation, to a newly-formed Delaware
       corporation that will be an indirect subsidiary of the Seller;

            (vii) CGU will sell all of the outstanding shares of Societe
       Generale held by it to one or more subsidiaries of the Seller; and

            (viii) the subsidiaries of CGU that hold shares of Munich Re will
       sell all of such shares to one or more subsidiaries of the Seller.

Cash and certain other proceeds of the sales and other dispositions contemplated
in clauses (iv) through (vii) of the prior sentence will be applied towards the
repayment of the outstanding promissory note made by CGU to the Seller in the
outstanding principal amount of $1,100,000,000 (the "TERM NOTE"), which Term
Note will be repaid in full in connection with the Acquisition.

       The aggregate purchase price (the "PURCHASE PRICE") payable by
Acquisition Co. to the Seller in connection with the Acquisition shall consist
of (a) cash equal to the sum of (1) an amount consistent with the Sources and
Uses Table, (2) any net income (loss) of CGU (net of (i) realized gains (losses)
in CGU's and its subsidiaries' fixed income portfolio and (ii) taxes) for the
period from June 1, 2000 through August 31, 2000 and (3) the difference between
(x) the amount of unrealized gains (losses) on CGU's and its subsidiaries'
investments in publicly traded common equity securities (other than Societe
Generale and Munich Re shares) as of August 31, 2000 and (y) the amount of
unrealized gains (losses) on such common securities as of May 31, 2000 (in the
case of each of (x) and (y), net of taxes), and (b) a seller note in an
aggregate principal amount consistent with the Sources and Uses Table. The
Purchase Price will be adjusted (up or down) by the difference between the
actual proceeds of the sales contemplated in clauses (iv)-(viii) of the first
sentence of the preceding paragraph (calculated on an after-tax basis in
accordance with the Stock Purchase Agreement) and the reference sales proceeds
set forth in the Stock Purchase Agreement.





                                                                       Annex III

                                 EXCHANGE NOTES

Guarantors:               Each guarantor in respect of the Credit Facilities
                          (the "GUARANTORS"; together with the Borrower, the
                          "CREDIT PARTIES").

Indenture Trustee:        To be agreed upon.

II. ISSUANCE OF EXCHANGE NOTES

Exchange Notes:           A holder of a Tranche C Term Loan may, at any time on
                          or after the date which is six months after the
                          Closing Date, exchange all or a portion of the Tranche
                          C Term Loan held by such holder for one or more
                          Exchange Notes in minimum denominations to be agreed
                          upon and in an aggregate principal amount equal to the
                          principal amount of the Tranche C Term Loan for which
                          it is exchanged. The Borrower will issue Exchange
                          Notes under an indenture that complies with the Trust
                          Indenture Act of 1939, as amended (the "INDENTURE").
                          The Borrower will appoint a trustee reasonably
                          acceptable to the Administrative Agent. The Exchange
                          Notes and the Indenture will be fully executed and
                          deposited into escrow on the Closing Date.

Ranking:                  The Exchange Notes shall rank pari passu with the
                          Credit Facilities.

Security:                 The Exchange Notes will be secured equally and ratably
                          with the Credit Facilities.

Maturity:                 The Exchange Notes will mature on the Tranche C Term
                          Loan Facility Maturity Date (as applying to the
                          Exchange Notes, the "EXCHANGE NOTE MATURITY DATE").





III. CERTAIN PAYMENT TERMS

Interest Rate:            The Exchange Notes will bear interest at a fixed rate
                          per annum of 13%.
                          Interest on the Exchange Notes will be payable
                          quarterly in arrears on the first business day of
                          each fiscal quarter of the Borrower, on the Exchange
                          Note Maturity Date and on the date of any prepayment
                          thereof. Interest will accrue on any overdue amount
                          (whether interest or principal, including defaulted
                          interest), to the extent lawful, at a rate per annum
                          equal to 200 basis points above the then current
                          interest rate until such amount (plus all accrued
                          and unpaid interest) is paid in full.

Optional Redemption:      The Borrower may redeem the Exchange Notes, in whole
                          or in part, at any time at a price equal to 100% of
                          the principal amount thereof (plus accrued and unpaid
                          interest if any to the date of redemption) plus a
                          make-whole premium calculated by discounting the
                          future interest payment and principal amortization at
                          maturity at a rate equal to the applicable US Treasury
                          rate plus 50 basis points, provided that no make-whole
                          premium shall be payable in connection with any
                          redemption resulting from asset sales.


IV. CERTAIN DOCUMENTATION MATTERS

Covenants:                The same as or less restrictive than the Credit
                          Facilities, as determined by the Administrative Agent
                          in its sole discretion.

Events of Default:        The Exchange Notes will have events of default that
                          are customary for an indenture governing similar
                          securities issued by issuers in a similar industry and
                          having similar credit statistics (but more restrictive
                          in certain respects, as determined by the
                          Administrative Agent in its sole discretion). Upon a
                          change of control, the Borrower shall offer to redeem
                          the Exchange Notes at 101% of the principal amount
                          thereof.

Transferability:          Transfers of the Exchange Notes will not be limited
                          except as otherwise provided by law.

Amendments:               Customary amendment provisions to be included in the
                          indenture with respect to the Exchange Notes.





Registration Rights:      The Borrower will be required to file a Shelf
                          Registration Statement with respect to the Exchange
                          Notes on or before the date which is six months after
                          the Closing Date (the "STEP-UP DATE"). The Borrower
                          and the Guarantors, jointly and severally, will pay
                          liquidated damages in the form of increased interest
                          of 50 basis points on the principal amount of Exchange
                          Notes outstanding to holders of Exchange Notes (i) if
                          the Shelf Registration Statement is not declared
                          effective by the SEC within 60 days of the Step-up
                          Date, until such Shelf Registration Statement is
                          declared effective, and (ii) during any period of time
                          (subject to customary exceptions) following the
                          effectiveness of the Shelf Registration Statement that
                          such Shelf Registration Statement is not available for
                          sales thereunder. After 12 weeks, the liquidated
                          damages shall increase by 50 basis points, and shall
                          increase by 50 basis points for each successive
                          12-week period thereafter to a maximum increase in
                          interest of 200 basis points (such damages to be
                          payable in the form of additional Exchange Notes, if
                          the interest rate thereon exceeds 14% PER ANNUM). In
                          addition, unless and until the Borrower has caused the
                          Shelf Registration Statement to become effective, the
                          holders of the Exchange Notes will have the right to
                          "piggy-back" in the registration of any debt or
                          preferred equity securities (subject to customary
                          scale-back provisions) that are registered by the
                          Company (other than on a Form S-4) unless all the
                          Exchange Notes will be redeemed or repaid from the
                          proceeds of such securities.
