PROSPECTUS SUPPLEMENT
(TO PROSPECTUS DATED OCTOBER 30,1997)

                     TERRA NOVA INSURANCE (UK) HOLDINGS PLC

                           7.2% SENIOR NOTES DUE 2007

                     GUARANTEED FULLY AND UNCONDITIONALLY BY

                       TERRA NOVA (BERMUDA) HOLDINGS LTD.

Exchange Offer Completed

         The Exchange Offer described in the accompanying Prospectus expired in
accordance with its terms on December 3, 1997. The entire outstanding issue of
$75.0 million principal amount of Old Notes (as defined in the accompanying
Prospectus) was exchanged for the Exchange Notes (as so defined). All references
in this Prospectus Supplement to the "Prospectus" shall mean the accompanying
Prospectus together with this Prospectus Supplement.

Market -Making Transactions

         Although the Exchange Notes have been listed on the Luxembourg Stock
Exchange, there is currently no active public market for the Exchange Notes.
Bermuda Holdings has been advised by Donaldson, Lufkin and Jenrette Securities
Corporation ("DLJSC") that it currently intends to make a market for the
Exchange Notes. The accompanying Prospectus, together with this Prospectus
Supplement, is for use by DLJSC in connection with offers and sales of the
Exchange Notes in market-making transactions at negotiated prices related to
prevailing market prices at the time of sale. DLJSC may act as principal or
agent in such transactions. DLJSC is not obligated to make a market for the
Exchange Notes and may discontinue any such market making at any time without
notice. Accordingly, no assurance can be given that an active trading market
will develop for, or as to the liquidity of, the Exchange Notes.

         DLJSC has provided financial or other advisory services to the Issuer
and Bermuda Holdings in the past and may do so in the future. In addition,
certain officers of DLJSC are directors of Bermuda Holdings and affiliates of
DLJSC own approximately 11.7% of the outstanding voting shares of Bermuda
Holdings.

Incorporation of Certain Documents by Reference

         The following documents filed by Bermuda Holdings with the Securities
and Exchange Commission are incorporated into the Prospectus by reference:

<PAGE>
 
          (1) Bermuda Holdings' Annual Report on Form 10-K for the year ended
     December 31, 1996;

         (2) Bermuda Holdings' Quarterly Reports on Form 10-Q for the quarters
ended March 31, 1997, June 30, 1997 and September 30, 1997; and

         (3) Bermuda Holdings Current Report on Form 8-K, dated August 28, 1997.

13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended, after the
date of this Supplement shall be deemed to be incorporated by reference into the
Prospectus and to be a part thereof.

         Any statement contained in a document incorporated or deemed to be
incorporated in the Prospectus, or contained in the Prospectus, shall be deemed
to be modified or superseded for purposes of the Prospectus to the extent that a
statement contained in the Prospectus or in any other subsequently filed
document which also is or is deemed to be incorporated by reference in the
Prospectus modifies or supersedes such statement. Any such statement so modified
or superseded shall not be deemed, except as so modified or superseded, to
constitute a part of the Prospectus.

   
         Bermuda Holdings will provide without charge to each person to whom the
Prospectus is delivered, upon the written or oral request of such person, a copy

                 OFFER TO EXCHANGE 7.2% SENIOR NOTES DUE 2007,
  WHICH WILL BE FULLY AND UNCONDITIONALLY GUARANTEED BY TERRA NOVA (BERMUDA)

                 UNDER THE SECURITIES ACT OF 1933 FOR ANY AND
                       ALL OLD NOTES (AS DEFINED BELOW)     
                                 ----------- 
    
     THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON
DECEMBER 3, 1997, UNLESS EXTENDED. AS DESCRIBED HEREIN, WITHDRAWAL RIGHTS WITH
RESPECT TO THE EXCHANGE OFFER ARE EXPECTED TO EXPIRE AT THE EXPIRATION OF THE
EXCHANGE OFFER.     

      Terra Nova Insurance (UK) Holdings plc, a public limited company organized
under the laws of England and Wales ("UK Holdings" or the "Issuer"), hereby
offers (the "Exchange Offer"), upon the terms and subject to the conditions set
forth in this Prospectus (the "Prospectus") and the accompanying Letter of
Transmittal (the "Letter of Transmittal"), to exchange up to $75.0 million
aggregate principal amount of its 7.2% Senior Notes due 2007 (the "Exchange
Notes") which will be fully and unconditionally guaranteed on a senior basis by
Terra Nova (Bermuda) Holdings Ltd. ("Bermuda Holdings"), and which have been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
pursuant to a Registration Statement of which this Prospectus is a part, for an
identical principal amount of its issued and outstanding 7.2% Senior Notes due
2007 (the "Old Notes"). The Exchange Notes and the Old Notes are collectively
referred to herein as the "Senior Notes." The Old Notes were originally issued
and sold in a transaction that was exempt from registration under the Securities
Act and resold inside the United States to certain qualified institutional
buyers in reliance on, and subject to the restrictions imposed pursuant to, Rule
144A under the Securities Act ("Rule 144A"). The terms of the Exchange Notes are
identical in all material respects to the terms of the Old Notes, except that
(i) the offer and sale of the Exchange Notes has been registered under the
Securities Act and therefore the Exchange Notes are not subject to certain
restrictions on transfer applicable to the Old Notes, will not bear legends
restricting the transferability thereof and will not be entitled to registration
rights or other rights under the Registration Rights Agreement (as defined
herein), and (ii) the Exchange Notes will not provide for any increase in the
interest rate pursuant to the Registration Rights Agreement, which rights and
provisions will terminate as to all of the Senior Notes upon the consummation of
the Exchange Offer. The Exchange Notes will be issued under the same Indenture
(as defined herein) as the Old Notes, and the Exchange Notes and the Old Notes
will constitute a single series of debt securities under the Indenture. In the
event the Exchange Offer is consummated, any Old Notes which remain outstanding
after consummation of the Exchange Offer and the Exchange Notes issued in the
Exchange Offer will vote together as a single class for purposes of determining
whether holders of a requisite percentage in outstanding principal amount of
Senior Notes have taken certain actions or exercised certain rights under the
Indenture. See "Description of Exchange Notes" and "The Exchange Offer."

     The Exchange Notes will mature on August 15, 2007. Interest on the Exchange
Notes will accrue from August 26, 1997, the issue date of the Old Notes, and is
payable semiannually on February 15 and August 15 of each year, commencing on
February 15, 1998. The Exchange Notes will be redeemable, in whole or in part,
at the option of the Issuer and at any time, at a redemption price equal to the
sum of: (i) the principal amount of the Exchange Notes being redeemed, plus
accrued and unpaid interest thereon to the redemption date, and (ii) the Make-
Whole Amount (as defined under "Description of Exchange Notes--Optional
Redemption"), if any. The Exchange Notes also may be redeemed under
circumstances described under "Description of Exchange Notes--Tax Redemption" at
100% of the principal amount thereof, plus accrued and unpaid interest thereon
to the redemption date. The Exchange Notes will not be subject to any mandatory
sinking fund payment.

     The Exchange Notes and the guarantee (the "Guarantee") of the Exchange
Notes by Bermuda Holdings will constitute unsecured senior obligations of the
Issuer and Bermuda Holdings, respectively. The Exchange Notes and the Guarantee
will rank pari passu in right of payment with all other senior indebtedness of
the Issuer and Bermuda Holdings, respectively, including indebtedness of
approximately $100 million pursuant to the Issuer's 10 3/4% Senior Notes due
2005 (the "1995 Senior Notes") which are fully and unconditionally guaranteed by
a guarantee of Bermuda Holdings, as well as any Old Notes not tendered for
exchange pursuant to the Exchange Offer. See "Description of Exchange Notes--
General" and "--Guarantee." As of the date hereof, there is no outstanding
indebtedness of either the Issuer or Bermuda Holdings which will be subordinate
to the Exchange Notes. Because the Issuer and Bermuda Holdings are holding
companies, in order for them to make interest and principal payments on the
Exchange Notes, they will be dependent on the payment of dividends by their
respective insurance company subsidiaries. As a consequence, the Exchange Notes
and the Guarantee will be effectively subordinated to all existing and future
liabilities of such insurance company subsidiaries, which at June 30, 1997
consisted principally of insurance liabilities and aggregated approximately $1.6
billion.
                                 ----------- 

     See "Risk Factors" commencing on page 12 for discussion of certain factors
that should be considered by holders of the Old Notes prior to tendering their
Old Notes in the Exchange Offer.
                                 ----------- 
    
     Until April 28, 1998 (180 days after the date of this Prospectus), all
dealers effecting transactions in registered securities, whether or not
participating in this distribution, may be required to deliver a prospectus.    
                                 ----------- 

 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
     EXCHANGE COMMISSION OR BY ANY STATE SECURITIES COMMISSION NOR HAS THE
          SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
            COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
             PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.
                                 ----------- 
    
              THE DATE OF THIS PROSPECTUS IS OCTOBER 30, 1997.     

<PAGE>
 
  (Cover Page Continued)
    
     The Issuer is making the Exchange Offer in reliance on the position of the
staff of the Division of Corporation Finance of the Securities and Exchange
Commission (the "Commission") as set forth in certain no-action letters
addressed to third parties in other transactions (including Exxon Capital
Holdings Corporation (available May 13, 1988), Morgan Stanley & Co. Incorporated
(available June 5, 1991), K-III Communications Corporation (available May 14,
1993) and Shearman & Sterling (available July 2, 1993)). However, neither the
Issuer nor Bermuda Holdings has sought its own no-action letter and there can be
no assurance that the staff of the Division of Corporation Finance of the
Commission would make a similar determination with respect to the Exchange Offer
as it has in such no-action letters to third parties. Based on these
interpretations by the staff of the Division of Corporation Finance, and subject
to the two immediately following sentences, the Issuer believes that the
Exchange Notes issued pursuant to this Exchange Offer in exchange for Old Notes
may be offered for resale, resold and otherwise transferred by a holder thereof
(other than a holder who is a broker-dealer or an "affiliate" of the Issuer or
Bermuda Holdings within the meaning of Rule 405 of the Securities Act) without
further compliance with the registration and prospectus delivery requirements of
the Securities Act, provided that such Exchange Notes are acquired in the
ordinary course of such holder's business and that such holder is not
participating, and has no arrangement or understanding with any Person to
participate, in a distribution (within the meaning of the Securities Act) of
such Exchange Notes. Any holder of Old Notes who is an "affiliate" of the Issuer
or Bermuda Holdings or who intends to participate in the Exchange Offer for the
purpose of distributing Exchange Notes, or any broker-dealer who purchased Old
Notes from the Issuer or Bermuda Holdings to resell pursuant to Rule 144A under
the Securities Act ("Rule 144A") or any other available exception under the
Securities Act, (a) will not be able to rely on the interpretations of the staff
of the Division of Corporation Finance of the Commission set forth in the above-
mentioned interpretive letters, (b) will not be permitted or entitled to tender
such Old Notes in the Exchange Offer and (c) must comply with the registration
and prospectus delivery requirement of the Securities Act in connection with any
sale or other transfer of such Old Notes unless such sale is made pursuant to an
exemption from such requirements. In addition, as described below, if any 
broker-dealer holds Old Notes acquired for its own account as a result of 
market-making or other trading activities and exchanges such Old Notes for 
Exchange Notes, then such broker-dealer must deliver a prospectus meeting the
requirements of the Securities Act in connection with any resales of such
Exchange Notes.     
     Each holder of Old Notes who wishes to exchange Old Notes for Exchange
Notes in the Exchange Offer will be required to represent that (i) it is not an
"affiliate" of the Issuer or Bermuda Holdings, (ii) any Exchange Notes to be
received by it are being acquired in the ordinary course of its business, and
(iii) it has no arrangement or understanding with any person to participate in a
distribution (within the meaning of the Securities Act) of such Exchange Notes.
Each broker-dealer that receives Exchange Notes for its own account pursuant to
the Exchange Offer must acknowledge that it acquired the Old Notes for its
account as the result of market-making activities or other trading activities
and must agree that it will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of such Exchange Notes. A broker-
dealer that acquired Old Notes in a transaction other than as part of its 
market-making or other trading activities will not be able to participate in the
Exchange Offer. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. Based on the position
taken by the staff of the Division of Corporation Finance of the Commission in
the no-action letters referred to above, the Issuer believes that broker-dealers
who acquired Old Notes for their own account as a result of market-making
activities or other trading activities ("Participating Broker-Dealers"), may
fulfill their prospectus delivery requirements with respect to the Exchange
Notes received upon exchange of such Old Notes (other than Old Notes which
represent an unsold allotment from the original sale of the Old Notes) with a
prospectus meeting the requirements of the Securities Act, which may be a
prospectus prepared for an exchange offer so long as it contains a description
of the plan of distribution with respect to the resale of such Exchange Notes.
Subject to certain provisions set forth in the Registration Rights Agreement,
the Issuer and Bermuda Holdings have agreed that this Prospectus, as it may be
amended or supplemented from time to time, may be used by a Participating 
Broker-Dealer in connection with resales of such Exchange Notes for a period
ending 180 days after the Expiration Date referred to below or, if earlier, when
all such Exchange Notes have been disposed of by such Participating Broker-
Dealer. See "Plan of Distribution." Any Participating Broker-Dealer who is an
"affiliate" of the Issuer or Bermuda Holdings may not rely on such no-action
letters and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction.
See "The Exchange Offer--Resales of the Exchange Notes."

     The Exchange Notes will be a new issue of securities for which there
currently is no market and there can be no assurance as to the liquidity of any
markets that may develop for the Exchange Notes or the ability of the holders to

                                       2

  (Cover Page Continued)

sell their Exchange Notes, as the case may be. Neither the Issuer nor Bermuda
Holdings currently intends to apply for listing of the Exchange Notes on any
securities exchange other than on the Luxembourg Stock Exchange or for quotation
through the National Association of Securities Dealers Automated Quotation
System.

     Any Old Notes not tendered and accepted in the Exchange Offer will remain
outstanding, will continue to accrue interest and will be entitled to all the
same rights and will be subject to the same limitations applicable thereto under
the Indenture (except for those rights which terminate upon consummation of the
Exchange Offer). Following consummation of the Exchange Offer, the holders of
Old Notes will continue to be subject to the existing restrictions upon transfer
thereof, and neither the Issuer nor Bermuda Holdings will have any further
obligation to such holders to provide for registration under the Securities Act
of the Old Notes held by such holders. To the extent that Old Notes are tendered
and accepted in the Exchange Offer, a holder's ability to sell untendered Old
Notes could be adversely affected. See "Prospectus Summary--Certain Consequences
of a Failure to Exchange Old Notes."

     THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF OLD NOTES ARE URGED TO READ THIS PROSPECTUS AND THE
RELATED LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING WHETHER TO TENDER THEIR
OLD NOTES PURSUANT TO THE EXCHANGE OFFER.
    
     Old Notes may be tendered for exchange on or prior to 5:00 p.m., New York
City time, December 3, 1997 (such time on such date being hereinafter called the
"Expiration Date"), unless the Exchange Offer is extended by the Issuer (in
which case the term "Expiration Date" shall mean the latest date and time to
which the Exchange Offer is extended). Tenders of Old Notes may be withdrawn at
any time on or prior to the Expiration Date. The Exchange Offer is not
conditioned upon any minimum principal amount of Old Notes being tendered for
exchange. However, the Exchange Offer is subject to certain events and
conditions and to the terms and provisions of the Registration Rights Agreement.
Old Notes may be tendered in whole or in part in a principal amount of $1,000
and integral multiples thereof. See "The Exchange Offer--Fees and Expenses."
Each Exchange Note will bear interest from the most recent date to which
interest has been paid or duly provided for on the Old Note surrendered in
exchange for such Exchange Note or, if no such interest has been paid or duly
provided for on such Old Note, from August 26, 1997. Holders of the Old Notes
whose Old Notes are accepted for exchange will not receive accrued interest on
such Old Notes.      

     Any waiver, extension or termination of the Exchange Offer will be publicly
announced by the Issuer or Bermuda Holdings through a release to the Dow Jones

                      ENFORCEABILITY OF CIVIL LIABILITIES

     The Issuer is a public limited company incorporated under the laws of
England and Wales, and Bermuda Holdings is a company incorporated under the laws
of Bermuda. All of the directors and executive officers of the Issuer, all of
the executive officers of Bermuda Holdings, six of the eleven directors of
Bermuda Holdings, and the experts named herein are non-residents of the United
States, and all or a substantial portion of the assets of the Issuer, Bermuda
Holdings and such persons are located outside the United States. It may not be
possible for investors to effect service of process within the United States
upon such persons or to enforce against any of them, the Issuer or Bermuda
Holdings judgments of courts of the United States predicated upon the civil
liability provisions of the federal or state securities laws of the United
States. The Issuer and Bermuda Holdings have been advised by their respective
counsel, Clifford Chance and Conyers, Dill & Pearman, that there is doubt as to
the enforceability in the United Kingdom and in Bermuda, in original actions or
in actions for enforcement of judgments of United States courts, of civil
liabilities predicated solely upon such securities laws.

     Bermuda Holdings has been informed by Conyers, Dill & Pearman that the
United States and Bermuda do not have a treaty providing for reciprocal
recognition and enforcement of judgments of U.S. courts in civil and commercial
matters and that a final judgment for the payment of money rendered by any
federal or state court in the United States based on civil liability, whether or
not predicated solely upon the U.S. federal securities laws, would, therefore,
not be automatically enforceable in Bermuda. Bermuda Holdings has also been
advised by Conyers, Dill & Pearman that a final and conclusive judgment obtained
in federal or state courts in the United States under which a sum of money is
payable as compensatory damages (i.e., not being a sum claimed by a revenue
authority for taxes or other charges of a similar nature by a governmental
authority, or in respect of a fine or penalty or multiple or punitive damages)
may be the subject of an action on a debt in the Supreme Court of Bermuda under
the common law doctrine of obligation. Such an action should be successful upon
proof that the sum of money is due and payable, without having to prove the
facts supporting the underlying judgment, as long as: (i) the court that gave
the judgment was competent to hear the action in accordance with private
international law principles as applied by the courts in Bermuda; and (ii) the
judgment was not contrary to public policy in Bermuda, was not obtained by fraud
or in proceedings contrary to the natural justice of Bermuda, and was not based
on an error in Bermuda law. A Bermuda court may impose civil liability on
Bermuda Holdings or its directors or officers in a suit brought in the Supreme
Court of Bermuda against Bermuda Holdings or such persons with respect to a
violation of U.S. federal securities laws, provided that the facts surrounding
such violation constitute or give rise to a cause of action under Bermuda law.

     Bermuda Holdings and the Issuer have each appointed CT Corporation System,
New York, New York, as its agent to receive service of process in actions
brought against it, arising out of or in connection with U.S. federal or state
securities laws or out of violations of such laws, in any federal or state court
in the United States relating to the transactions covered by this Prospectus.

                                    CURRENCY

     In this Prospectus, references to "U.S. dollars," "$" or "cents" are to
U.S. currency, and references to "pounds," "sterling," "(Pounds)", "pence" or
"p" are to U.K. currency. Bermuda Holdings publishes its consolidated financial

                               COMPANY OVERVIEW

  Overview and Markets

     The Company is a specialty property, casualty and marine insurance and
reinsurance company operating on a worldwide basis through subsidiaries in the
London company market and Lloyd's of London (together the "London Market"), in
the Bermuda Market, in the European Market and through branch offices in
Toronto, Canada and Brussels, Belgium. Terra Nova Insurance Company Limited
("Terra Nova"), the Company's predecessor and principal subsidiary, was
established in 1969 and is believed by management to be one of the largest
London Market companies (as defined below). The Company had gross premiums
written of $331.8 million for the six months ended June 30, 1997, and had
combined shareholders' equity of $422.3 million at June 30, 1997.

     The London Market is one of the world's largest insurance and reinsurance
marketplaces and attracts business from clients throughout the world who seek
flexible and innovative protection for a wide variety of risks. The London
Market is composed of Lloyd's and companies with underwriting offices in
proximity to Lloyd's ("London Market companies") and, management believes, had
gross written premiums of approximately $26.0 billion in 1995.

     The Bermuda Market, comprised of both captive and independent companies, in
recent years has become one of the world's largest insurance and reinsurance
markets in which international business is written. Management believes that the
Bermuda Market's gross premiums written were approximately $23.4 billion in
1995, up from approximately $13.0 billion in 1990.

  Business, Profitability and Financial Strength

     The Company's principal lines of business consist of classes of (i) non-
marine property coverage written largely on a reinsurance basis, (ii) non-marine
casualty coverage written both on a primary and a reinsurance basis, and (iii)
marine coverage written both on a primary and a reinsurance basis, accounting
for approximately 49.5%, 18.9% and 31.1%, respectively, of the Company's gross
premiums written for 1996. Additionally, of the Company's gross premiums written
for 1996, approximately 66.8% consisted of reinsurance business and
approximately 46.4%, 10.8%, 20.4% and 22.4% were attributable to clients from
the U.S., U.K., Europe and the rest of the world, respectively.

     The Company and Terra Nova have a demonstrated history of profits, having
been profitable in every year of their combined 27-year existence, except for
1980 and 1992. The combined ratio and operating ratio of the Company's insurance
subsidiaries averaged 101.9% and 77.1%, respectively, for the period from 1993
through 1996. For the six months ended June 30, 1997, the Company had a combined
ratio and operating ratio of 99.4% and 75.8%, respectively. The Company's income
from continuing operations before income taxes, interest expense, depreciation,
amortization and minority interests ("EBITDA") was $97.0 million for 1996 and
$51.2 million for the six months ended June 30, 1997.

     At June 30, 1997, approximately 85.1% of the Company's $1.3 billion
investment portfolio consisted of fixed maturity debt securities, 97.6% were
rated "A" or better by Standard & Poor's Corporation ("S&P") and Moody's
Investors Service, Inc. ("Moody's") and the remaining 2.4%, although not rated,
were, in the opinion of management, at least the equivalent in quality of "AA"
rated investments. The Company currently has no investments in high yield fixed
income securities, real estate or mortgages.

  Strategy/Strategic Initiatives

     The Company seeks to enhance its record of profitable growth through its
operating and growth strategies. The key elements of its operating strategy
consist of:

     . Flexible operating structure. The Company, with subsidiaries in the
       London company market, Lloyd's, the Bermuda Market and in Paris and
       having offices in London, Bermuda, Toronto and Brussels, believes that it
       has a significant competitive advantage through its presence in many of
       the principal markets where insurance and reinsurance business is
       transacted. By writing business in many of the major international
       markets, the Company is able to diversify the risk of its portfolio
       geographically and, at the same time, take advantage of differences in
       rates and deductibles throughout the world. Having developed an expertise
       in writing specific classes of non-marine property, non-marine casualty
       and marine businesses which may react differently to varying market
       conditions, the Company may shift its mix of business to those lines
       where the Company believes the potential for profitable results is
       greater, while continuing to maintain a smaller presence in less
       profitable lines in anticipation of market improvements.

     . Low operating costs. Through an international brokerage system, the
       Company has access not only to the London and Bermuda Markets, but also
       to other international insurance and reinsurance centers. By using this
       variable cost distribution system and operating through a centralized
       administration organization in London, the Company is able to minimize
       its fixed overhead costs and therefore better control expense levels as
       market conditions for writing insurance and reinsurance fluctuate. In
       addition, with operations in Bermuda, the Company is able to take
       advantage of Bermuda's favorable tax regime.

     . Significant levels of investment income. With a $1.3 billion
       conservatively managed investment portfolio as of June 30, 1997, the
       Company has been able to generate significant and consistent levels of
       investment income that have helped to stabilize profits. Of the $1.3
       billion of invested assets at June 30, 1997, $816.5 million were held by
       Terra Nova and $451.0 million were held by Terra Nova (Bermuda), with the
       balance held by other group companies. The impact of investment income on
       the Company's results is evidenced by the average operating ratio of the
       Company's insurance subsidiaries over the last four years of 77.1%.

       The proceeds from the offering of the Old Notes have and will enable
       the Company to further its growth strategy, which includes:

     . Capital growth. With an expected total capitalization of $597.3 million
       after giving effect to proceeds from the offering of the Old Notes, the
       Company expects to continue to increase its business writings in selected
       areas and to pursue strategic acquisitions which management believes will
       enhance the Company's presence in targeted markets or provide products
       for the group as a whole, including the acquisition of Corifrance (as
       described below).

     . Expected further participation in the Octavian Syndicates. The Company
       has provided $293.9 million of the Octavian Syndicates' total
       underwriting capacity for the 1997 year of account. Based on the Octavian
       Syndicates' recent utilization of capacity, the Company estimates that
       such premiums written and included in its 1997 financial statements will
       be between $175 and $200 million. The Company expects to increase the
       capacity available to the Octavian Syndicates for the 1998 year of
       account. In addition to providing additional capacity to the Octavian
       Syndicates, the Company may increase its involvement in Lloyd's in the
       future, through acquiring the rights to manage additional syndicates or
       employing additional underwriters. The number of syndicates managed by
       Octavian increased to seven for the 1997 year of account.

     . Growth in continental Europe. On September 8, 1997, the Company acquired
       Compagnie de Reassurance d'Ile de France, Corifrance, based in Paris.
       Corifrance is a French reinsurance company which transacts business
       internationally, although mainly outside the United States. Its premium
       volume in 1996 was $25 million.

                                        Delivery Procedures."

Resales of Exchange Notes............   The Issuer is making the Exchange Offer
                                        in reliance on the position of the staff
                                        of the Division Corporation Finance of
                                        the Commission as set forth in certain
                                        no-action letters addressed to third
                                        parties in other transactions (including
                                        Exxon Capital Holdings Corporation
                                        (available May 13, 1988), Morgan Stanley
                                        & Co. Incorporated (available June 5,
                                        1991), K-III Communications Corporation
                                        (available May 14, 1993) and Shearman &
                                        Sterling (available July 2, 1993)).
                                        However, neither the Issuer nor Bermuda
                                        Holdings has sought its own no-action
                                        letter and there can be no assurance
                                        that the staff of the Division of
                                        Corporation Finance of the Commission
                                        would make a similar determination with
                                        respect to the Exchange Offer as it has
                                        in such interpretive letters to third
                                        parties. Based on these interpretations
                                        by the staff of the Division of
                                        Corporation Finance, and subject to the
                                        two immediately following sentences, the
                                        Issuer believes that Exchange Notes
                                        issued pursuant to this Exchange Offer
                                        in exchange for Old Notes may be offered
                                        for resale, resold and otherwise
                                        transferred by a holder thereof (other
                                        than a holder who is a broker-dealer or
                                        an "affiliate" of the Issuer or Bermuda

                                        of the Securities Act) without further

                                        prospectus delivery requirements of the
                                        Securities Act, provided that such
                                        Exchange Notes are acquired in the
                                        ordinary course of such holder's
                                        business and that such holder is not
                                        participating, and has no arrangement or
                                        understanding with any person to
                                        participate, in a distribution (within
                                        the meaning of the Securities Act) of
                                        such Exchange Notes. However, any holder
                                        of Old Notes who is an "affiliate" of
                                        the Issuer or Bermuda Holdings or who
                                        intends to participate in the Exchange

                                        the Exchange Notes, or any broker-dealer
                                        who purchased the Old Notes from the
                                        Issuer or Bermuda Holdings to resell
                                        pursuant to Rule 144A or any other
                                        available exemption under the Securities
                                        Act, (a) will not be able to rely on the
                                        interpretations of the staff of the
                                        Division of Corporation Finance of the
                                        Commission set forth in the above-
                                        mentioned interpretive letters, (b) will
                                        not be permitted or entitled to tender
                                        such Old Notes in the Exchange Offer and
                                        (c) must comply with registration and
                                        prospectus delivery requirements of the
                                        Securities Act in connection with any

                                        addition, as described below, if any
                                        broker-dealer holds Old Notes acquired

                                        activities will not be able to
                                        participate in the Exchange Offer. The
                                        Letter of Transmittal states that by so
                                        acknowledging and by delivering a
                                        prospectus, a broker-dealer will not be
                                        deemed to admit that it is an
                                        "underwriter" within the meaning of the
                                        Securities Act. Based on the position
                                        taken by the staff of the Division of
                                        Corporation Finance of the Commission in
                                        the no-action letters referred to above,
                                        the Issuer believes that broker-dealers
                                        who acquired Old Notes for their own
                                        accounts as a result of market-making

                                        the requirements of the Securities Act,
                                        which may be the prospectus prepared for

                              THE EXCHANGE NOTES

Securities Offered...................   Up to $75.0 million principal amount of
                                        7.2% Senior Notes due 2007. The Exchange
                                        Notes will be issued and the Old Notes
                                        were issued under an Indenture dated as
                                        of August 26, 1997 (the "Indenture")
                                        between the Issuer, Bermuda Holdings and
                                        The Chase Manhattan Bank (the
                                        "Trustee"). The Exchange Notes and any
                                        Old Notes which remain outstanding after
                                        consummation of the Exchange Offer will
                                        constitute a single series of debt
                                        securities under the Indenture and,
                                        accordingly, will vote together as a
                                        single class for purposes of determining
                                        whether holders of the requisite
                                        percentage in outstanding principal
                                        amount thereof have taken certain
                                        actions or exercised certain rights
                                        under the Indenture. See "Description of
                                        Exchange Notes--General." The terms of
                                        the Exchange Notes are identical in all
                                        material respects to the terms of the
                                        Old Notes, except that (i) the offer and
                                        sale of the Exchange Notes have been
                                        registered under the Securities Act and
                                        therefore the Exchange Notes are not
                                        subject to certain restrictions on
                                        transfer applicable to the Old Notes,
                                        will not bear legends relating thereto
                                        and will not be entitled to registration
                                        rights or other rights under the
                                        Registration Rights Agreement, and (ii)
                                        the Exchange Notes will not provide for
                                        any increase in the interest rate
                                        thereof, which rights and provision will
                                        terminate as to all of the Senior Notes
                                        upon the consummation of the Exchange
                                        Offer. See "Description of Old Notes"
                                        and "Description of Exchange Notes."

Maturity Date........................   August 15, 2007.

Interest.............................   Interest on the Exchange Notes will
                                        accrue at the rate of 7.2% per annum and
                                        is payable semi-annually on February 15
                                        and August 15 of each year, commencing

                                        will bear interest from August 26, 1997,
                                        the issue date for the Old Notes.
                                        Holders of the Old Notes whose Old Notes
                                        are accepted for exchange will not
                                        receive accrued interest on such Old
                                        Notes and will be deemed to have waived
                                        the right to receive any interest on
                                        such Old Notes accrued, from and after
                                        August 26, 1997.

Guarantee............................   The Exchange Notes will be fully and
                                        unconditionally guaranteed on a senior
                                        basis by Bermuda Holdings. See
                                        "Description of Exchange Notes--
                                        Guarantee."

Ranking..............................   The Exchange Notes and the Guarantee
                                        will constitute unsecured senior
                                        obligations of the Issuer and Bermuda
                                        Holdings, respectively, and will rank
                                        pari passu in right of payment with all
                                        other senior indebtedness, if any, of
                                        the Issuer and Bermuda Holdings,
                                        respectively. Because the Issuer and
                                        Bermuda Holdings are holding companies,
                                        the Exchange Notes and the Guarantee
                                        will be effectively subordinated to all
                                        existing and future liabilities of their
                                        respective insurance company
                                        subsidiaries. See "Risk Factors--Holding
                                        Company Structure; Dividend
                                        Restrictions."

Optional Redemption..................   The Exchange Notes are redeemable at the
                                        option of the Issuer at any time in
                                        whole or in part, at a redemption price
                                        equal to the sum of (i) the principal
                                        amount of the Exchange Notes being
                                        redeemed, plus accrued and unpaid
                                        interest thereon to the redemption date,
                                        and (ii) the Make-Whole Amount, if any.

                                        withholding of taxes is required by any
                                        Relevant Jurisdiction (as defined
                                        herein) with respect to interest
                                        payments to United States holders of the
                                        Exchange Notes. See "Description of
                                        Exchange Notes--Tax Redemption."     

Listing..............................   The Issuer intends to list the Exchange
                                        Notes on the Luxembourg Stock Exchange.

Absence of Market for the Exchange
 Notes...............................   The Exchange Notes will be a new issue
                                        of securities for which there currently
                                        is no market and there can be no
                                        assurance as to the liquidity of any
                                        market that may develop for the Exchange
                                        Notes or the ability of the holders to
                                        sell their Exchange Notes, as the case
                                        may be. The Issuer and Bermuda Holdings
                                        currently do not intend to apply for
                                        listing of the Exchange Notes on any
                                        securities exchange other than the
                                        Luxembourg Stock Exchange or for
                                        quotation through the National
                                        Association of Securities Dealers
                                        Automated Quotation System.

Use of Proceeds......................   Neither the Issuer nor Bermuda Holdings
                                        will receive any cash proceeds from the
                                        issuance of the Exchange Notes offered
                                        hereby. The net proceeds received from
                                        the issuance and sale of the Old Notes
                                        were used to increase the capital and
                                        surplus of the subsidiaries of the
                                        Issuer and for general corporate
                                        purposes, including the acquisition of
                                        Corifrance. See "Use of Proceeds."

Book-Entry; Form......................  The Exchange Notes will initially be
                                        issued as one or more global notes
                                        without coupons in bearer form (the
                                        "Global Note"), which will be deposited
                                        with Chase Manhattan Bank Luxembourg
                                        S.A., as custodian thereof (the
                                        "Custodian"), for the benefit of The
                                        Chase Manhattan Bank, as depositary (the
                                        "Depositary"), pursuant to the
                                        Depositary Agreement (as defined
                                        herein). The Depositary will issue one
                                        or more global receipts representing the
                                        Exchange Notes, which will be delivered
                                        and registered in the name of DTC or its
                                        nominee. Beneficial interests in the
                                        Exchange Notes will be shown on, and
                                        transfers thereof effective only
                                        through, the records maintained in book-
                                        entry form by DTC and its participants.
                                        See "Description of Exchange Notes--
                                        General" and "Description of Depositary
                                        Agreement--General."

            CERTAIN CONSEQUENCES OF A FAILURE TO EXCHANGE OLD NOTES

     The sale of the Old Notes was not registered under the Securities Act or
any state securities laws and therefore the Old Notes may not be offered, sold
or otherwise transferred, except in compliance with the registration
requirements of the Securities Act and any other applicable securities laws, or
pursuant to an exemption therefrom or in a transaction not subject thereto, and
in each case in compliance with certain other conditions and restrictions,
including the Issuer's, Bermuda Holdings' and the Trustee's right in certain
cases to require the delivery of opinions of counsel, certifications and other
information prior to any such transfer. Old Notes which remain outstanding after
consummation of the Exchange Offer will continue to bear a legend reflecting
such restrictions on transfer. In addition, upon consummation of the Exchange
Offer, holders of Old Notes which remain outstanding will not be entitled to any
rights to have the resale of such Old Notes registered under the Securities Act
or to any similar rights under the Registration Rights Agreement. Neither the
Issuer nor Bermuda Holdings currently intends to register under the Securities
Act the resale of any Old Notes which remain outstanding after consummation of
the Exchange Offer.

     To the extent that Old Notes are tendered and accepted in the Exchange
Offer, a holder's ability to sell untendered Old Notes could be adversely
affected. In addition, although the Old Notes are eligible for trading in the
Depositary's Same-Day

                                      13
<PAGE>
 
Funds Settlement System, to the extent that Old Notes are tendered and accepted
in connection with the Exchange Offer, any trading market for Old Notes which
remain outstanding after the Exchange Offer could be adversely affected.

     The Exchange Notes and any Old Notes which remain outstanding after
consummation of the Exchange Offer will constitute a single series of debt
securities under the Indenture and, accordingly, will vote together as a single
class for purposes of determining whether holders of the requisite percentage in
outstanding principal amount thereof have taken certain actions or exercised
certain rights under the Indenture. See "Description of Exchange Notes--
General."

     The Old Notes provide that, in the event the Exchange Offer is not
consummated or a Shelf Registration Statement (as defined herein) is not
declared effective on or prior to February 26, 1998, then the annual interest
rate borne by the Old Notes shall be increased to 7.45%. If the Exchange Offer
is not consummated or a Shelf Registration Statement is not declared effective
by May 26, 1998, then the annual interest rate borne by the Old Notes shall be
increased to 7.7%. Upon consummation of the Exchange Offer or the effectiveness
of such Shelf Registration Statement, the interest rate borne by the Old Notes
will return to 7.2%.

                                  RISK FACTORS

     In addition to the other information contained in this Prospectus the
following should be considered carefully in evaluating an investment in the
Exchange Notes offered hereby.


Holding Company Structure; Dividend Restrictions

     The Issuer is a holding company whose primary assets are the capital stock
of Terra Nova, Octavian, Terra Nova Capital and Corifrance, and Bermuda Holdings
is a holding company whose primary assets are the capital stock of the Issuer
and Terra Nova (Bermuda). A substantial amount of the Issuer's cash flow is
derived from dividends from Terra Nova and substantially all of the Bermuda
Holdings' cash flow is derived from dividends from the Issuer and Terra Nova
(Bermuda). The payment of dividends and other payments by Terra Nova and Terra
Nova (Bermuda) is subject to restrictions under U.K. law and Bermuda law,
respectively.

     Under U.K. company law, Terra Nova may not declare or pay a dividend except
from its distributable profits, which is its accumulated realized profits (so
far as not previously used by distribution or capitalization) less its
accumulated realized losses (so far as not previously written off in a reduction
or reorganization of capital). U.K. insurance company law and regulation require
an insurance company, such as Terra Nova, to maintain a minimum level of
solvency and provide that such a company may only pay a dividend to the extent
that the dividend would not reduce such company's net assets below its minimum
level of solvency. In addition, before Terra Nova may declare or pay any
dividend, it is required to give 14 days' advance notice to the U.K. Secretary
of State for Trade and Industry acting through the U.K. Department of Trade and
Industry (the "DTI"), which may direct that no such declaration or payment be
made.

     Under Bermuda insurance law, Terra Nova (Bermuda) is prohibited from
declaring or paying any dividends during any financial year if it is in breach
of its "minimum solvency margin" or "minimum liquidity ratio" or if the
declaration or payment of such dividends would cause it to fail to meet such
margin or ratio. Furthermore, if Terra Nova (Bermuda) fails to meet its minimum
solvency margin or minimum liquidity ratio on the last day of any financial
year, it will be prohibited, without the approval of the Minister of Finance of
Bermuda (the "Minister"), from declaring or paying any dividends during the next
financial year. In addition, under The Companies Act 1981, a company may not pay
a dividend or make a distribution out of contributed surplus if there are
reasonable grounds for believing that (a) the company is, or would be, after the
payment unable to pay its liabilities as they become due, or (b) the realizable
value of the company's assets would thereby be less than the aggregate of its
liabilities and its issued share capital and share premium accounts.

     There can be no assurance as to the exact amount of dividend payments, if
any, which the DTI will permit Terra Nova to make in the future or as to what
the standards for dividend payments by Terra Nova or Terra Nova (Bermuda) will
be in the future. Moreover, the surplus of each of Terra Nova and Terra Nova
(Bermuda) will be affected by the value of its respective investment portfolio,
which is sensitive to interest rate changes.

     Because the Issuer and Bermuda Holdings are holding companies, the Exchange
Notes and the Guarantee are effectively subordinated to all existing and future
liabilities of their respective insurance company subsidiaries which at June 30,
1997 consisted principally of insurance liabilities and aggregated $1.6 billion
calculated in accordance with GAAP.

Ability to Service Interest and Principal Payments on the Senior Notes

     The Issuer expects to satisfy its interest payment obligations with respect
to the Senior Notes from dividend payments made by Terra Nova as well as capital
subscriptions and other payments from Bermuda Holdings. Similarly, Bermuda
Holdings' ability to fulfill the Guarantee or to make capital subscriptions and
other payments to the Issuer is based on dividend payments by the Issuer or
Terra Nova (Bermuda). Neither the Issuer nor Bermuda Holdings intends to
establish a sinking fund with respect to the Senior Notes. To the extent
dividends or other monies received by the Issuer or Bermuda Holdings are
insufficient to make, directly or through the Guarantee, interest payments on
the Senior Notes and principal payments on the Senior Notes at maturity or upon
the occurrence of an Event of Default (as defined herein), the Company
anticipates that it may have to borrow additional funds or sell some of its
assets. There can be no assurance that such actions could be effected on
satisfactory terms, in a timely manner or at all, that they would enable the
Issuer or Bermuda Holdings to make any of the foregoing payments on the Senior
Notes or that any such actions would be permitted under the Indenture.


                                      15

Leverage

     As of June 30, 1997, and after giving effect to the issuance and sale of
the Senior Notes, the Company had outstanding indebtedness of approximately $175
million and shareholders' equity of approximately $422.3 million.

     The 1995 indenture pursuant to which the 1995 Senior Notes were issued,
subject to certain limitations, and the Indenture (collectively, the
"Indentures") permit the Company to incur additional indebtedness. Management
believes that cash flow from operations, together with other available sources
of liquidity, will be adequate to permit the Issuer to make required payments of
principal and interest on its indebtedness and to fund the working capital
requirements of its operating subsidiaries, although there can be no assurance
that this will be the case. To the extent that cash flow from operations is
insufficient to satisfy the Company's cash requirements, the Company may seek to
obtain funds from additional borrowings, sell a portion of the Company's
business, investment securities or other assets, engage in other transactions,
raise additional equity capital or acquire other businesses that would provide
cash flow (in all such cases to the extent permitted by the Indentures). There
can be no assurance that such actions could be effected on satisfactory terms,
in a timely manner or at all, that they would enable the Issuer or Bermuda
Holdings to make any of the payments due on the Senior Notes or that any such
actions would be permitted under the Indentures.

     The Company's leverage could make the Company vulnerable to changes in
general economic conditions and impair the Company's ability to obtain
additional financing for working capital, acquisitions or general corporate
purposes. In addition, as noted above, Bermuda Holdings and the Issuer are
dependent on dividend payments from subsidiaries to meet their obligations,
including obligations under the Senior Notes.


Cyclicality of Insurance and Reinsurance Industry; Industry Developments

     The property, casualty and marine insurance and reinsurance industry has a
history of being highly cyclical. Demand for reinsurance is influenced
significantly by underwriting results of primary property, casualty and marine
insurers and prevailing general economic and market conditions, all of which
affect liability retention decisions of primary insurers and reinsurance premium
rates. The supply of insurance and reinsurance is related directly to prevailing
prices and levels of surplus capacity which, in turn, fluctuate in response to
changes in rates of return on investments being realized in the property,
casualty and marine insurance and reinsurance industry.

     As a result of the catastrophe losses suffered during the late 1980s and
the early 1990s and the contraction in reinsurance capacity caused by the
withdrawal of a number of the Company's competitors, property catastrophe
reinsurance rates hardened significantly and retentions increased sharply during
the period 1991 through 1993. In 1994, 1995 and 1996, property catastrophe
reinsurance rates fell from the strong levels of 1993. Management believes, in
light of its experience with the Company's renewals for 1997 business and
because of the absence of a major catastrophic event, that premium rates have
declined in 1997, but that rates and retention levels in the near future are
likely to remain substantially higher than those experienced in 1992.

     Premium rates for U.S. casualty insurance and reinsurance have generally
declined since 1990, primarily because of more predictable forms of coverage,
such as claims made, and the effects of lower inflationary expectations. This
has resulted in more competitive conditions which have continued in 1997.

     Since the substantial rate and deductible increases for marine insurance in
the 1992 and 1993 underwriting years, prices generally stabilized in 1994 and
1995 and fell in 1996. In 1997 management believes that increased competition
will lead generally to a further decline in rates. Increased deductibles play an
important role in reducing the number of very small claims. In the past, this
business was characterized by large volumes of very small claims, arising from
very low levels of deductibles which had remained unchanged for a number of
years, during which repair costs rose due to inflation and currency
fluctuations.

     There can be no assurance that rates and/or underwriting terms and
conditions will not deteriorate further or at other times in the future as a
result of additional capital provided by recent or future market entrants or for
other reasons. Consolidations within the insurance industry may also reduce the
demand for reinsurance, which may adversely affect rates and/or underwriting
terms and conditions.

Competition

     The property and casualty insurance and reinsurance industry is highly
competitive. The Company competes for its business in the United States and
internationally with other Lloyd's syndicates, other London Market companies,
other domestic Bermuda reinsurers, domestic United States insurers and
reinsurers and other international insurers and reinsurers, many of whom are
larger and have greater financial resources than the Company. Additionally,
other well-capitalized insurers and reinsurers could start writing, or increase
their writing of, the classes of business in which the Company is primarily
engaged.

     Competition in the classes of business which the Company writes is based on
many factors, including the perceived overall financial strength of the insurer
or reinsurer, claims paying ability rating, premiums charged and other terms and
conditions, services provided, reputation and perceived technical ability and
experience of staff. Management of the Company believes that its principal
competitive strengths are its management and operational flexibility, its
expertise in risk assessment and underwriting skills and its relationships with
Lloyd's brokers, other leading brokers and reinsurance intermediaries.

     Ratings have become an increasingly important factor in establishing the
competitive position of insurance and reinsurance companies. Terra Nova and
Terra Nova (Bermuda) carry A, A- and A+ claims paying ability ratings by S&P,
A.M. Best and Duff & Phelps, respectively, which is lower than those held by
some of its principal competitors. S&P and Duff & Phelps ratings range from a
high "AAA" to a low "CCC", while A.M. Best ratings range from a high "A++" to a
low "C-."

     Claims paying ability ratings are based upon a review of publicly available
information and communications between rating agency analysts and the insurance
company's management. Such ratings are the opinion of the rating agency giving
the rating and are not directed toward the protection of investors.

Adequacy of Loss Reserves

     The Company establishes loss reserves for the ultimate payment of all
losses and loss adjustment expenses (LAE) incurred with respect to its business.
The loss and LAE liabilities consist of two components: case reserves and
incurred but not reported (IBNR) reserves. Case reserves are estimates of future
loss payments with respect to insured events which have been reported to the
insurer. These reports may be made formally by the cedent or informally by other
means, such as evaluation of claims by attorneys. The Company determines case
reserves on a contract by contract basis. The amount reserved is the amount
expected to be ultimately paid and is not discounted or otherwise adjusted for
the time value of money. IBNR reserves are actuarially determined and reflect
(i) the estimated ultimate loss amount which will be paid by the insurer and
(ii) an estimate of possible changes in the value of those claims which have
already been reported to the insurer. The particular method of setting IBNR
reserves depends upon the class of business involved. The specific techniques
involve the use of projections and models based on the Company's or the relevant
market's experience and exposure. IBNR reserves reflect a margin for the
uncertainty involved as determined by sensitivity tests. While management
believes that the Company's reserves for losses and LAE are adequate, there can
be no assurances that the Company's ultimate losses and LAE will not deviate,
perhaps substantially, from the estimates reflected in its financial statements.
If the Company's reserves should prove to be inadequate, the Company will be
required to increase reserves, which could have a material adverse effect on the
Company's financial condition.

Regulation

     Terra Nova is a U.K. insurance company authorized by the DTI to carry on
insurance business (including reinsurance) in the U.K. and is subject to
regulation and supervision in the U.K. by the DTI. The Insurance Companies Act
1982, as amended, imposes on U.K. insurance companies numerous requirements,
including capital, solvency, liquidity and management standards and auditing and
reporting requirements, and further grants to the DTI powers to supervise,
investigate and intervene in the affairs of U.K. insurance companies. As is
often the practice of the DTI in connection with a substantial change of control
of a U.K. insurance company, Terra Nova is currently subject to a Notice of
Requirements issued by the DTI on May 22, 1995 (as modified by notices dated
April 3 and 4, 1996) which, among other things, (i) requires 14 days' advance
notice of the declaration or payment of dividends, which declaration or payment
may be limited or prohibited by the DTI, (ii) requires Terra Nova to give notice
and, in some instances, obtain DTI consent, prior to entering into certain
transactions with connected persons and (iii) limits the annual amount of gross
premiums that may be written by Terra Nova. Each of Terra Nova Capital and
Octavian are subject to regulation and supervision by Lloyd's, including the
imposition of capital, solvency and management standards.



                                      17

     Terra Nova (Bermuda) is a registered Bermuda insurance company and is
   subject to regulation and supervision in Bermuda. The Insurance Act 1978, as
   amended, imposes on Bermuda insurance companies capital, solvency and
   liquidity standards and auditing and reporting requirements.

     Neither Terra Nova nor Terra Nova (Bermuda) is registered or licensed as an
   insurance company in any jurisdiction in the United States. Nevertheless,
   each state of the United States regulates to an extent the sale of insurance
   by foreign insurers such as Terra Nova and Terra Nova (Bermuda). The
   administration of insurance laws and regulations in the United States is
   vested in state agencies that have broad powers and are concerned primarily
   with the protection of policyholders. The status of foreign insurance
   companies within the insurance regulatory framework in the United States has
   been subject to increased scrutiny by the National Association of Insurance
   Commissioners (the "NAIC"), state legislatures and insurance regulators, as
   well as the U.S. Congress.

     While it is not possible to predict the future impact of changing law or
   regulation on the Company's operations, such changes could have a material
   adverse effect on the Company and the insurance industry in general.

   Tax Matters

     The Company believes that neither Terra Nova nor Terra Nova (Bermuda) will
   be subject to U.S. tax, other than U.S. excise tax on premiums of Terra Nova
   (Bermuda) with respect to risks located in the United States and withholding
   tax on certain U.S. source income, because neither engages in a trade or
   business in the United States. However, since definitive identification of
   activities that constitute being engaged in a U.S. trade or business is not
   provided by the Internal Revenue Code (the "Code") or Treasury Regulations or
   court decisions, there can be no assurance that the Internal Revenue Service
   (the "Service") will not contend that Terra Nova (Bermuda) or Terra Nova is
   engaged in a U.S. trade or business.

     If Terra Nova (Bermuda) were considered to be engaged in a U.S. trade or
   business, it would be subject to U.S. federal income tax at regular corporate
   rates on income attributable to its U.S. trade or business, except to the
   extent provided by the income tax treaty between the U.S. and Bermuda (the
   "Bermuda Treaty"), and might also be subject to a 30% "branch profits" tax.
   There can be no assurance that Terra Nova (Bermuda) is entitled, or in the
   future will be entitled, to benefits under the Bermuda Treaty. However, if
   Terra Nova (Bermuda) were so entitled and were considered to be engaged in a
   U.S. trade or business, it would not be subject to U.S. federal income tax at
   regular corporate rates except on income attributable to a U.S. permanent
   establishment. Terra Nova (Bermuda) might, however, be subject to the U.S.
   branch profits tax if it were engaged in a U.S. trade or business, even if it
   did not have a permanent establishment in the United States. Although the
   Company believes that Terra Nova (Bermuda) does not have a U.S. permanent
   establishment, there can be no assurance that the Service will not contend
   otherwise.

     If any subsidiary of UK Holdings were considered to be engaged in a U.S.
   trade or business, that entity would be subject to U.S. federal income tax at
   regular corporate rates on income attributable to its U.S. trade or business
   and might also be subject to branch profits tax, except to the extent
   provided by the income tax treaty between the U.S. and U.K. (the "U.K.
   Treaty"). The Company believes that the subsidiaries of UK Holdings will be
   qualified residents of the U.K. entitled to benefits under the U.K. Treaty
   and that, accordingly, even if any of those entities were considered to be
   engaged in a U.S. trade or business, it would be subject to U.S. federal
   income tax at regular corporate rates only on income attributable to a U.S.
   permanent establishment and would not be subject to the branch profits tax.
   Although the Company believes that none of the subsidiaries of UK Holdings
   has a U.S. permanent establishment, there can be no assurance that the
   Service will not contend otherwise.

     If the Company or any of its subsidiaries were considered to be subject to
   U.S. federal income tax in any of the ways described above, the Company's
   results of operations could be materially adversely affected.

   Absence of Public Market for the Exchange Notes

     There is no existing market for the Exchange Notes and there can be no
   assurance as to the liquidity of any markets that may develop for the
   Exchange Notes or the ability of the holders to sell their Exchange Notes, as
   the case may be.  Future trading prices of the Exchange Notes will depend on
   many factors including, among other things, general economic conditions,
   government legislation or regulation, prevailing interest rates, the Issuer's
   and Bermuda Holdings' operating results, and the market for similar
   securities.

   Enforcement of Judgments

     All of the directors and executive officers of the Issuer, all of the
   executive officers of Bermuda Holdings, six of the eleven directors of
   Bermuda Holdings, and the experts named herein are non-residents of the
   United States, and all or a substantial portion of the assets of the Issuer,
   Bermuda Holdings and most such persons are located outside the United States.
   It may not be possible for investors to effect service of process within the
   United States upon such persons or to enforce against any of them, the Issuer
   or Bermuda Holdings judgments of courts of the United States predicated upon
   the civil liability provisions of the federal or state securities laws of the
   United States. The Issuer and Bermuda Holdings have been advised by their
   respective counsel, Clifford Chance and Conyers, Dill & Pearman, that there
   is doubt as to the enforceability in the United Kingdom and in Bermuda, in
   original actions or in actions for enforcement of judgments of United States
   courts, of civil liabilities predicated solely upon such securities laws.

   Investment Performance

     The Company's investment portfolio consists primarily of investment grade
   securities with fixed maturities. The market value of the Company's
   investments varies depending on economic and market conditions. Absent other
   factors, the market values of fixed maturity securities are likely to decline
   as interest rates rise. The Company may, from time to time, for business or
   regulatory reasons, be required to sell certain of its investments at a time
   when their market value is less than the cost of such investments.

(1) The 1992 loss resulted primarily from (i) the unprecedented losses from
    prior underwriting years in the LMX marine account, (ii) the frequency and
    severity of catastrophe losses (primarily Hurricanes Andrew and Iniki)
    experienced in that year, and (iii) large losses in the Company's aviation
    account.
(2) Capital and surplus under U.K. and Bermuda law, respectively.
(3) EBITDA consists of earnings before interest, taxes, minority interest,
    depreciation and amortization. EBITDA is presented here not as a measure of
    operating results, but rather as a measure of the Company's cash flow and
    debt service ability, and should not be considered as an alternative to net
    earnings and cash flows determined in accordance with GAAP. Because the
    Company's ability to obtain dividends from its insurance subsidiaries may be
    subject to certain restrictions, EBITDA is not necessarily indicative of the
    Company's ability to service its indebtedness.
(4) Adjusted EBITDA is comprised of EBITDA excluding realized gains or losses on
    sales of investments.
(5) Loss and loss adjustment expense ratio represents the sum of losses and loss
    adjustment expenses as a percentage of net premiums earned.
(6) Underwriting expense ratio represents underwriting expenses as a percentage
    of net premiums earned.
(7) Combined ratio represents the sum of the loss and loss adjustment expense
    ratio and underwriting expense ratio.
(8) Operating ratio represents the combined ratio less the ratio of net
    investment income to net premiums earned.



                      RATIO OF EARNINGS TO FIXED CHARGES

</TABLE>

     In determining the ratio of earnings to fixed charges, earnings are defined
as earnings from continuing operations before income taxes and fixed charges.
Fixed charges consist of the total of interest on all indebtedness, amortization
of deferred debt issuance costs and one-third of operating lease rental expense
deemed representative of the interest factor. The ratio of earnings to fixed
charges has not been adjusted to reflect minority interests because the shares
of capital stock which comprise such minority interests are not entitled to
dividends until debt serviced payments on the Senior Notes have been made. Terra
Nova had no indebtedness through December 21, 1994, the date of its acquisition
by Bermuda Holdings.

     Neither the Issuer nor Bermuda Holdings will receive any cash proceeds from
   the issuance of the Exchange Notes offered hereby.  The net proceeds received
   from the issuance and sale of the Old Notes were used to increase the capital
   and surplus of subsidiaries of the Issuer and for general corporate purposes,
   including the acquisition of Corifrance.

                         DESCRIPTION OF EXCHANGE NOTES

   General

     The Old Notes were and the Exchange Notes will be issued pursuant to an
   Indenture (the "Indenture"), dated as of August 26, 1997, among the Issuer,
   Bermuda Holdings and The Chase Manhattan Bank, as trustee (the "Trustee").
   The Indenture has been filed as an exhibit to the registration statement (the
   "Registration Statement") of which this Prospectus forms a part.  The
   Indenture will be qualified by the Trust Indenture Act of 1939, as amended
   (the "Trust Indenture Act") upon the effectiveness of the Registration
   Statement. The terms of the Exchange Notes will include those stated in the
   Indenture and those made part of the Indenture by reference to the Trust
   Indenture Act. The Exchange Notes are subject to all such terms, and holders
   of Exchange Notes are referred to the Indenture and the Trust Indenture Act
   for a statement thereof. The following summary of certain provisions of the
   Indenture does not purport to be complete and is qualified in its entirety by
   reference to the Indenture, including the definitions therein of certain
   terms used below. The following description of the terms of the Exchange
   Notes and the guarantee thereof by Bermuda Holdings pursuant to the Indenture
   or pursuant to guarantees endorsed on the Exchange Notes (both forms of
   guarantee are hereinafter referred to collectively as the "Guarantee") sets
   forth certain terms and provisions of the Exchange Notes and the Guarantee.
   The definitions of certain general terms used in the following summary are
   set forth below under "--Certain Definitions."

     The Exchange Notes will rank senior in right of payment to all subordinated
   indebtedness of the Issuer and pari passu in right of payment with all
   indebtedness of the Issuer not expressly subordinated or secured. The
   Exchange Notes will be fully and unconditionally guaranteed on a senior basis
   by Bermuda Holdings, and the obligations of Bermuda Holdings under the
   Guarantee will rank senior in right of payment to all subordinated
   indebtedness of Bermuda Holdings and pari passu in right of payment with all
   indebtedness of Bermuda Holdings not expressly subordinated or secured.

       The Exchange Notes and the Old Notes are sometimes referred to as,
   collectively, the "Senior Notes" and, individually, a "Senior Note."

       The Old Notes and the Exchange Notes will constitute a single series of
   debt securities under the Indenture.  If the Exchange Offer is consummated,
   holders of Old Notes who do not exchange their Old Notes for Exchange Notes
   will vote together with the holders of Exchange Notes for all relevant
   purposes under the Indenture.  In that regard, the Indenture requires that
   certain actions by the holders thereunder (including acceleration following
   an "Event of Default") must be taken, and certain rights must be exercised,
   by specified minimum percentages of the aggregate principal amount of the
   outstanding debt securities.  In determining whether holders of the requisite
   percentage and principal amount have given any notice, consent or waiver or
   taken any other action permitted under the Indenture, any Old Notes which
   remain outstanding after the Exchange Offer will be aggregated with the
   Exchange Notes, and the holders of such Old Notes and Exchange Notes will
   vote together as a single series for all such purposes.  Accordingly, all
   references herein to specified percentages in aggregate principal amount of
   the outstanding Senior Notes shall be deemed to mean, at any time after the
   Exchange Offer is consummated, such percentage in aggregate principal amount
   of the Old Notes and Exchange Notes then outstanding.

     The Old Notes were issued and the Exchange Notes will initially be issued
   as one or more Global Notes, which Exchange Notes will be deposited with the
   Custodian, as custodian thereof for the Depositary, pursuant to the Deposit
   and Custody Agreement, dated as of August 26, 1997 (the "Depositary
   Agreement"), among the Issuer, Bermuda Holdings, the Custodian and the
   Depositary. For a description of the Depositary Agreement, see "Description
   of Depositary Agreement." The Depositary will issue one or more Global
   Receipts representing the Exchange Notes, each of which the Depositary will
   deliver to and register in the name of DTC or its nominee. Unless and until
   all of the beneficial interests in the Global Notes ("Book-Entry Interests")
   are exchanged for Definitive Senior Notes (as defined herein), the depositary
   interest to be held by DTC may not be transferred except as a whole by DTC to
   a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or
   by DTC or any such nominee to a successor of DTC or a nominee of such
   successor.

    The Issuer intends to list the Exchange Notes on the Luxembourg Stock
   Exchange.


   Guarantee

     Bermuda Holdings will fully and unconditionally guarantee on a senior basis
   to each holder of an Exchange Note the due and punctual payment of the
   principal of and any premium and interest on such Exchange Note (and any
   Additional Amounts (as defined herein) payable by the Issuer or Bermuda
   Holdings in respect thereof) when and as the same shall

                                      23
<PAGE>
 
   become due and payable, whether at stated maturity, by declaration of
   acceleration, call for redemption or otherwise, in accordance with the terms
   of the Exchange Notes and the Indenture. Bermuda Holdings' obligations under
   the Guarantee will be as if it were a principal debtor and not merely a
   surety, and will be absolute and unconditional, irrespective of, and will be
   unaffected by, any invalidity, irregularity or unenforceability of any
   Exchange Note or the Indenture, any failure to enforce the provisions of any
   Exchange Note or the Indenture, any waiver, modification or indulgence
   granted to the Issuer with respect thereto, by the holder of any Exchange
   Note or the Trustee, or any other circumstances which may otherwise
   constitute a legal or equitable discharge of a surety or guarantor, provided,
   however, that, notwithstanding the foregoing, no such waiver, modification or
   indulgence shall, without the consent of Bermuda Holdings, increase the
   principal amount of an Exchange Note or the interest rate thereon or increase
   any premium payable upon redemption thereof.

   Principal, Maturity and Interest

     The Senior Notes are limited in an aggregate principal amount to $75.0
   million. The Senior Notes will mature on August 15, 2007. Interest on the
   Senior Notes accrues at the rate of 7.2% per annum and is payable semi-
   annually in arrears in cash on each February 15 and August 15, commencing
   February 15, 1998 (each, an "Interest Payment Date"), to holders of record on
   the immediately preceding January 31 and July 31, respectively. Each Exchange
   Note will bear interest from August 26, 1997, the issue date of the Old
   Notes.  Holders of the Old Notes whose Old Notes are accepted for exchange
   will not receive any accrued interest on such Old Notes, and will be deemed
   to have waived the right to receive any such accrued interest. Interest is to
   be computed on the basis of a 360-day year of twelve 30-day months.

   Optional Redemption

     The Issuer shall have the right to redeem the Senior Notes, in whole or in
   part, at any time and from time to time, subject to the receipt of any
   consent required under the terms of any Indebtedness of the Issuer which may
   be outstanding from time to time, upon not less than 30 nor more than 60 days
   notice, at a redemption price equal to the sum of (i) the principal amount of
   the Senior Notes being redeemed, plus accrued and unpaid interest thereon to
   the redemption date, and (ii) the Make-Whole Amount, if any, with respect to
   such Senior Notes.

     "Make-Whole Amount" means, in connection with any optional redemption of
   any Senior Notes, the excess, if any, of (i) the sum, as determined by a
   Quotation Agent (as defined herein) of the present values of the principal
   amount of such Senior Notes, together with scheduled payments of interest
   from the redemption date to the Stated Maturity of the Senior Notes, in each
   case discounted to the redemption date on a semi-annual basis (assuming a
   360-day year consisting of twelve 30-day months) at the Adjusted Treasury
   Rate (as defined herein) over (ii) 100% of the principal amount of the Senior
   Notes to be redeemed.

     "Adjusted Treasury Rate" means, with respect to any redemption date, the
   rate per annum equal to the semi-annual equivalent yield to maturity of the
   Comparable Treasury Issue, calculated using a price for the Comparable
   Treasury Issue (expressed as a percentage of its principal amount) equal to
   the Comparable Treasury Price for such redemption date, calculated on the
   third Business Day preceding the redemption date, plus in each case .20%.

     "Comparable Treasury Issue" means the United States Treasury security
   selected by the Quotation Agent as having a maturity comparable to the
   remaining term from the redemption date to the Stated Maturity Date of the
   Senior Notes that would be utilized, at the time of selection and in
   accordance with customary financial practice, in pricing new issues of
   corporate debt securities of comparable maturity to the remaining term of the
   Senior Notes.

     "Quotation Agent" means the Reference Treasury Dealer appointed by the
   Issuer. "Reference Treasury Dealer" means: (i) Donaldson, Lufkin & Jenrette
   Securities Corporation and its respective successors; provided, however, that
   if the foregoing shall cease to be a primary U.S. Government securities
   dealer in New York City (a "Primary Treasury Dealer"), the Issuer shall
   substitute therefor another Primary Treasury Dealer; and (ii) any other
   Primary Treasury Dealer selected by the Indenture Trustee after consultation
   with the Company.

     "Comparable Treasury Price" means, with respect to any redemption date, (i)
   the average of the bid and asked prices for the Comparable Treasury Issue
   (expressed in each case as a percentage of its principal amount) on the third
   Business Day preceding such redemption date, as set forth in the daily
   statistical release (or any successor release) published by the Federal
   Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for
   U.S. Government Securities" or (ii) if such release (or any successor
   release) is not published or does not contain such prices on such Business
   Day, (A) the average of the Reference Treasury Dealer Quotations for such
   redemption date, after excluding the highest and lowest such Reference

                                      24
<PAGE>
 
   Treasury Dealer Quotations, or (B) if the Quotation Agent obtains fewer than
   three such Reference Treasury Dealer Quotations, the average of all such
   Quotations.

     "Reference Treasury Dealer Quotations" means, with respect to each
   Reference Treasury Dealer and any redemption date, the average, as determined
   by the Quotation Agent, of the bid and asked prices for the Comparable
   Treasury Issue (expressed in each case as a percentage of its principal
   amount) quoted in writing to the Indenture Trustee by such Quotation Agent at
   5:00 p.m., New York City time, on the third Business Day preceding such
   redemption date.

     "Additional Amounts" means such additional amounts as may be necessary in
   order that the amount of distributions then due and payable by the Issuer on
   the outstanding Senior Notes shall not be reduced as a result of any
   additional taxes, duties or other governmental charges to which the Issuer
   has become subject as a result of an event described in "--Tax Redemption."

     Notice of any redemption will be mailed at least 30 days but not more than
   60 days before the redemption date to each holder of Senior Notes to be
   redeemed at its registered address. Unless the Issuer defaults in payment of
   the redemption price, on and after the redemption date interest ceases to
   accrue on such Senior Notes called for redemption.

     If the Issuer is required to pay any additional taxes, duties or other
   governmental charges as a result of an event described in "--Tax Redemption,"
   the Issuer will pay on the Senior Notes the Additional Amounts.

   Tax Redemption

     The Senior Notes may also be redeemed at the option of the Issuer, in whole
   but not in part, upon not less than 30 nor more than 60 days' notice given as
   provided in the Indenture, at any time at a redemption price equal to 100% of
   the principal amount thereof, together with accrued and unpaid interest to
   the date fixed for redemption if (a) the Issuer is required to issue
   Definitive Senior Notes (other than upon the request of a holder of Book-
   Entry Interests following an Event of Default) after using all reasonable
   efforts to avoid having to issue such Definitive Senior Notes and the Issuer
   is or would be so required in the absence of any applicable tax treaty on the
   next succeeding Interest Payment Date to pay Additional Amounts with respect
   to any of the Senior Notes as described under "--Payment of Additional
   Amounts" or (b) the Issuer or Bermuda Holdings is or would be so required in
   the absence of any applicable tax treaty on the next succeeding Interest
   Payment Date to pay Additional Amounts with respect to the Senior Notes as
   described under "--Payment of Additional Amounts," and, in either case, the
   payment of such Additional Amounts cannot be avoided by the use of any
   reasonable measures available to the Issuer.

     The Issuer or Bermuda Holdings will also pay, or make available for
   payment, to holders of Senior Notes on the redemption date any Additional
   Amounts (as described, but subject to the exceptions referred to, under  "--
   Payment of Additional Amounts") resulting from the payment of such redemption
   price.

   Selection and Notice

     For information with respect to the redemption of Book-Entry Interests, see
   "Description of Depositary Agreement--Redemption or Repurchase." With respect
   to any outstanding Definitive Senior Notes, if less than all of the
   definitive registered Senior Notes (the "Definitive Senior Notes") are to be
   redeemed at any time, selection of Definitive Senior Notes for redemption
   will be made by the Trustee on a pro rata basis, by lot or by such other
   method as the Trustee deems fair and appropriate and in compliance with the
   requirements of such principal national securities exchange, if any, on which
   the Senior Notes are listed or, if the Senior Notes are not so listed, on a
   pro rata basis, by lot or by such other method as the Trustee deems fair and
   appropriate; provided that no Definitive Senior Notes with a principal amount
   of $1,000 or less shall be redeemed in part. With respect to any Definitive
   Senior Notes, notice of redemption shall be mailed by first class mail at
   least 30 but not more than 60 days before the redemption date to each holder
   of Definitive Senior Notes to be redeemed at its registered address. If any
   Definitive Senior Note is to be redeemed in part only, the notice of
   redemption that relates to such Definitive Senior Note shall state the
   portion of the principal amount thereof to be redeemed. A new Definitive
   Senior Note in principal amount equal to the unredeemed portion thereof will
   be issued in the name of the holder thereof upon cancellation of the original
   Definitive Senior Note. On and after the redemption date, interest will cease
   to accrue on all Senior Notes or portions thereof called for redemption. The
   Issuer or Bermuda Holdings will comply with the Exchange Act and the rules
   and regulations of the Commission thereunder to the extent applicable to any
   such redemption.

                                      25

   Liens

     The Indenture provides that Bermuda Holdings will not, and will not permit
   any of its Restricted Subsidiaries to, directly or indirectly, create, incur,
   assume or suffer to exist any Lien securing Indebtedness (other than
   Permitted Liens) on any property or asset now owned or hereafter acquired, or
   on any income or profits therefrom or assign or convey any right to receive
   income therefrom, unless all payments due under the Indenture and the Senior
   Notes are secured on an equal and ratable basis with (or prior to) the
   obligations so secured until such time as such obligations are no longer
   secured by a Lien.

   Reports

     Whether or not required by the Exchange Act, so long as any Senior Notes
   are outstanding, Bermuda Holdings will furnish to the holders of Senior Notes
   all financial information that would be required to be contained in a filing
   with the Commission on Form 10-K, 10-Q or 8-K if Bermuda Holdings were
   required to file such form, including a "Management's Discussion and Analysis
   of Results of Operations and Financial Condition," and, with respect to the
   annual financial statements only, a report thereon by Bermuda Holdings'
   independent public accountants. In addition, whether or not required by the
   Exchange Act, Bermuda Holdings will file a copy of all such information and
   reports with the Commission for public availability (unless the Commission
   will not accept such a filing) and make such information available to
   investors who request it in writing. See "Available Information."

   Merger, Consolidation or Sale of Assets

     The Indenture provides that after the Issue Date, Bermuda Holdings will
   not, in any transaction, consolidate with or merge with or into any other
   Person or, directly or indirectly, sell, or otherwise dispose of all or
   substantially all of its assets in one or more related transactions to any
   Person or group of affiliated Persons unless, at the time and after giving
   effect thereto:

        (i)(A) Bermuda Holdings shall be the continuing corporation, or (B) the
     Person (if other than Bermuda Holdings) formed by such consolidation, or
     into which Bermuda Holdings is merged, or the Person that acquires by sale
     or other disposition the assets of Bermuda Holdings, substantially as an
     entirety (the "Surviving Entity"), is a corporation duly organized and
     validly existing under the laws of the United States, the United Kingdom,
     Bermuda, the Republic of Ireland, Barbados, the Channel Islands, the Cayman
     Islands or any other jurisdiction that is not materially adverse to the
     holders of the Senior Notes and shall, in the case of clause (B), expressly
     assume, by supplemental indenture, executed and delivered to the Trustee,
     in form reasonably satisfactory to the Trustee, all the obligations of
     Bermuda Holdings under the Guarantee and the Indenture;

        (ii) immediately before and after such transaction, giving effect to
     such transaction, no Default or Event of Default shall have occurred and be
     continuing;

        (iii) immediately after giving effect to such transaction on a pro forma
     basis, the Consolidated Net Worth (after giving pro forma effect to such
     transaction but not including the effect of any purchase accounting
     adjustments or the accrual of deferred tax liabilities resulting from the
     transaction) of Bermuda Holdings (or the Surviving Entity if Bermuda
     Holdings is not the continuing obligor with respect to the Guarantee under
     the Indenture) is at least equal to the Consolidated Net Worth of Bermuda
     Holdings immediately before such transaction;

        (iv) if any of the property or assets of Bermuda Holdings would
     thereupon become subject to any Lien, the outstanding Senior Notes shall be
     secured equally and ratably with (or prior to) the obligation or liability
     secured by such Lien, unless Bermuda Holdings could create such Lien
     without equally and ratably securing the Senior Notes; and

        (v) Bermuda Holdings (or the Surviving Entity if Bermuda Holdings is not
     the continuing obligor with respect to the Guarantee under the Indenture)
     shall be entitled to all the benefits of the Tax Sharing Agreement.

     In connection with any consolidation, merger, transfer or lease
   contemplated hereby, Bermuda Holdings shall deliver to the Trustee an
   officers' certificate and an opinion of counsel, each stating that such
   consolidation, merger, transfer or lease and the supplemental indenture in
   respect thereto comply with the provisions described herein and that all
   conditions precedent provided for in the Indenture relating to such
   transaction have been complied with.

                                      26
<PAGE>
 
     Upon any consolidation or merger or any sale, assignment, transfer, lease
   or conveyance or other disposition of all or substantially all of the assets
   of Bermuda Holdings in accordance with the provisions described in the second
   preceding paragraph, the successor Person formed by such consolidation or
   into which Bermuda Holdings is merged or to which such sale, assignment,
   conveyance, transfer, lease or other disposition is made shall succeed to,
   and be substituted for, and may exercise every right and power of Bermuda
   Holdings under the Indenture with the same effect as if such successor Person
   had been named as Bermuda Holdings therein. When a successor assumes all the
   obligations of its predecessor under the Indenture and the Senior Notes, the
   predecessor will be released from those obligations; provided that, in the
   case of a transfer by lease, the predecessor corporation shall not be
   released from the payment of principal and interest on the Senior Notes.


   Payment of Additional Amounts

     All payments on the Senior Notes, and all payments pursuant to any
   Guarantee, will be made without deduction or withholding, for or on account
   of any and all present and future taxes, duties, assessments, or governmental
   charges of whatever nature unless the deduction or withholding of such taxes,
   duties, assessments or governmental charges is then required by law. If any
   deduction or withholding for or on account of any present or future taxes,
   assessments or other governmental charges of the U.K., Bermuda or any
   relevant jurisdiction or any political subdivision or taxing authority
   thereof or therein (the "Relevant Jurisdiction") shall at any time be
   required in respect of any amounts to be paid under the Senior Notes or under
   the Guarantee, the Issuer or Bermuda Holdings, as applicable, will pay or
   cause to be paid such additional amounts ("Additional Amounts") as may be
   necessary in order that the net amounts received by a holder of a Senior Note
   after such deduction or withholding shall be not less than the amounts
   specified in such Senior Note to which such holder is entitled; provided,
   however, that the Issuer or Bermuda Holdings, as applicable, shall not be
   required to make any payment of Additional Amounts for or on account of:

        (a) any tax, assessment or other governmental charge which would not
     have been imposed but for (i) the existence of any present or former
     connection between such holder (or between a fiduciary, settlor,
     beneficiary, member or shareholder of, or possessor of a power over, such
     holder, if such holder is an estate, nominee, trust, partnership or
     corporation), otherwise than merely by the holding of a Senior Note or the
     receipt of amounts payable in respect of such Senior Notes, and any
     Relevant Jurisdiction or such holder being subject to the jurisdiction of
     any Relevant Jurisdiction, including, without limitation, such holder (or
     such fiduciary, settlor, beneficiary, member, shareholder or possessor)
     being or having been a citizen or resident thereof or being or having been
     present or engaged in trade or business therein or having or having had a
     permanent establishment therein or (ii) the presentation of the Senior Note
     (where presentation is required) for payment on a date more than 30 days
     after the date on which such payment became due and payable or the date on
     which payment thereof is duly provided for, whichever occurs later, except
     to the extent that the holder would have been entitled to Additional
     Amounts had the Senior Notes been presented on the last day of such period
     of 30 days;

        (b) any tax, assessment, or other governmental charge that is imposed or
     withheld by reason of the failure to comply by the holder of the Global
     Note or, if different, the beneficial owner of the interest payable on the
     Global Note, with a timely request of the Issuer addressed to such holder
     or beneficial owner to provide information, documents or other evidence
     concerning the nationality, residence, identity or connection with the
     taxing jurisdiction of such holder or beneficial owner which is required or
     imposed by a statute, treaty, regulation or administrative practice of the
     taxing jurisdiction as a precondition to exemption from all or part of such
     tax, assessment or governmental charge;

        (c) payments in respect of Definitive Senior Notes issued at the request
     of the holder (including on or after the occurrence of an Event of
     Default); or

        (d) any combination of items (a), (b) and (c) above;

   nor shall Additional Amounts be paid with respect to any payment of the
   principal of, or any interest on, any Senior Note to any holder who is a
   fiduciary or partnership or other than the sole beneficial owner of such
   payment to the extent that a beneficiary or settlor with respect to such
   fiduciary or member of such partnership or beneficial owner would not have
   been entitled to any Additional Amounts had such beneficiary, settlor, member
   or beneficial owner been the holder of such Senior Note.

   Events of Default and Remedies

     The Indenture provides that each of the following constitutes an Event of
   Default (whatever the reason for such Event of Default and whether or not it
   shall be voluntary or involuntary or be effected by the operation of law or
   pursuant to any judgment, decree or order of any court or any order, rule or
   regulation of any administrative or governmental body):

     default or breach for a period of 60 days after there has been given, by
     registered or certified mail, to the Issuer or Bermuda Holdings, as the
     case may be, by the Trustee or to the Issuer or Bermuda Holdings, as the
     case may be, and the Trustee by the holders of at least 25% in principal
     amount of the outstanding Senior Notes a written notice specifying such
     default or breach and stating that such notice is a "Notice of Default"; or

        (iv)(A) an event of default shall have occurred under any mortgage,
     bond, indenture, loan agreement or other document evidencing any issue of
     Indebtedness of Bermuda Holdings or any Restricted Subsidiary for money
     borrowed (or the payment of which is guaranteed by Bermuda Holdings or any
     of its Restricted Subsidiaries), which issue has an aggregate outstanding
     principal amount of not less than $10.0 million, and such default shall
     have resulted in such Indebtedness becoming, whether by declaration or
     otherwise, due and payable prior to the date on which it would otherwise
     become due and payable, or (B) a default in any payment when due at final
     Stated Maturity of any such Indebtedness outstanding in an aggregate
     principal amount of not less than $10.0 million and, in each case, 10
     Business Days shall have elapsed after such event during which period such
     event shall not have been cured or rescinded or such Indebtedness shall not
     have been satisfied; or

        (v) final judgments or orders are rendered against Bermuda Holdings, the
     Issuer or any Restricted Subsidiary by a court or regulatory agency of
     competent jurisdiction which require the payment in money, either
     individually or in an aggregate amount, that is more than $10.0 million
     (other than any judgment to the extent a reputable non-affiliated insurance
     company has accepted liability) and such judgment or order shall not be
     discharged and either (A) any creditor shall have commenced an enforcement
     proceeding upon such judgment or order, which enforcement proceeding shall
     have remained unstayed for a period of 10 days, or (B) a period of 60 days
     during which a stay of enforcement shall not be in effect shall have
     elapsed following the date on which any period for appeal has expired; or

        (vi) a decree or order is entered (A) for relief in respect of the
     Issuer, Bermuda Holdings or any Principal Insurance Subsidiary in an
     involuntary case or other bankruptcy proceeding under applicable law, or
     (B) adjudging the Issuer, Bermuda Holdings or any Principal Insurance
     Subsidiary a bankrupt or insolvent, or seeking reorganization, arrangement,
     adjustment or composition of or in respect of the Issuer, Bermuda Holdings
     or any Principal Insurance Subsidiary under applicable law, or appointing a
     custodian, receiver, liquidator, assignee, trustee, sequestrator (or other

     official) of any of the Issuer, Bermuda Holdings or any Principal Insurance
     Subsidiary or of any substantial part of its property, or makes an
     assignment for the benefit of creditors, or admits in writing its inability
     to pay its debts generally as they become due or takes corporate action in
     furtherance of any such action; or

        (viii) default in the performance, or breach, of the provisions

     If any Event of Default (other than an Event of Default described in (vi)
   or (vii) above) occurs and is continuing, the Trustee or the holders of at
   least 25% in principal amount of the outstanding Senior Notes, by written
   notice to the Issuer (and to the Trustee, if such notice is given by the
   holders), may, and the Trustee at the request of such holders shall, declare
   all unpaid principal of, premium, if any, and accrued interest on all the
   Senior Notes to be due and payable immediately. Notwithstanding the
   foregoing, in the case of an Event of Default described in (vi) or (vii)
   above, all outstanding Senior Notes will become due and payable without
   further action or notice. Holders of the Senior Notes may not enforce the
   Indenture or the Senior Notes except as provided in the Indenture. Subject to
   certain limitations, holders of a majority in principal amount of the then
   outstanding Senior Notes may direct the Trustee in its exercise of any trust
   or power. The Trustee may withhold from holders of the Senior Notes notice of
   any continuing Default or Event of Default (except a Default or Event of
   Default relating to the payment of principal or interest) if the board of
   directors, the executive committee or a trust committee of directors and/or
   Responsible Officers (as defined in the Indenture) of the Trustee determine
   in good faith that withholding such notice is in the interest of the holders.

     After a declaration of acceleration, but before a judgment or decree for
   payment of the money due has been obtained by the Trustee, the holders of at
   least a majority in aggregate principal amount of the outstanding Senior
   Notes, by written notice to the Issuer and the Trustee, may annul such
   declaration if: (i) the Issuer or Bermuda Holdings has paid or deposited with
   the Trustee a sum sufficient to pay (A) all sums paid or advanced by the
   Trustee under the Indenture and the reasonable compensation, expenses,
   disbursements and advances of the Trustee, its agents and counsel, (B) all
   overdue interest on all Senior Notes, (C) the principal of and premium, if
   any, on any Senior Notes which have become due otherwise than by such
   declaration of acceleration and interest thereon at the rate borne by the
   Senior Notes and (D) to the extent that payment of such interest is lawful,
   interest upon overdue interest at the rate borne by the Senior Notes; and
   (ii) all Events of Default, other than the non-payment of principal of the
   Senior Notes which have become due solely by such declaration or
   acceleration, have been waived as provided in the Indenture or cured. No such
   rescission shall affect any subsequent default or impair any right consequent
   thereon.

     The holders of a majority in aggregate principal amount of the outstanding
   Senior Notes by notice to the Trustee may on the behalf of the holders of all
   of the Senior Notes waive any existing or past Default or Event of Default
   and its consequences under the Indenture except a continuing Default or Event
   of Default in the payment of interest on, or the principal of, or premium, if
   any, on the Senior Notes or in respect of covenants or provisions in the
   Indenture which cannot be modified or amended without the consent of the
   holders of a greater percentage of the principal amount of, or all of, the
   outstanding Senior Notes.

     The Issuer and Bermuda Holdings are required to deliver to the Trustee
   annually a statement regarding compliance with the Indenture, and the Issuer
   is required, upon becoming aware of any Default or Event of Default, to
   deliver to the Trustee a statement specifying such Default or Event of
   Default.

   No Personal Liability of Directors, Officers, Employees and Stockholders

     No director, officer, employee or stockholder of the Issuer, Bermuda
   Holdings or any Subsidiary of Bermuda Holdings, as such, shall have any
   liability for any obligations of the Issuer or Bermuda Holdings under the
   Senior Notes, the Guarantee or the Indenture or for any claim based on, in
   respect of, or by reason of, such obligations or their creation. Each holder
   of the Senior Notes by accepting a Senior Note waives and releases all such
   liability. The waiver and release are part of the consideration for issuance
   of the Senior Notes. Such waiver may not be effective to waive liabilities
   under the federal securities laws and it is the view of the Commission that
   such a waiver is against public policy.

   Defeasance or Covenant Defeasance

     Under certain conditions, each of the Issuer or Bermuda Holdings may, at
   its option and at any time, elect to have the obligations of the Issuer and
   Bermuda Holdings discharged with respect to the outstanding Senior Notes and
   the Guarantee ("defeasance"). Such defeasance means that the Issuer and
   Bermuda Holdings shall be deemed to have paid and discharged the entire
   indebtedness represented by the outstanding Senior Notes and the Guarantee,
   except for: (i) the rights of holders of outstanding Senior Notes to receive
   payments in respect of the principal of, premium, if any, and interest on
   such Senior Notes when such payments are due, or on the redemption date, as
   the case may be; (ii) the Issuer's obligations with respect to the Senior
   Notes concerning issuing temporary Senior Notes, registration of Senior
   Notes, mutilated, destroyed, lost or stolen Senior Notes and the maintenance
   of an office or agency for payment and money for security payments held in
   trust;

                                      29
<PAGE>
 
   (iii) the rights, powers, trust, duties and immunities of the Trustee, and
   the Issuer's and Bermuda Holdings' obligations in connection therewith; (iv)
   the defeasance provisions of the Indenture; and (v) the obligations of the
   Issuer and Bermuda Holdings to pay any Additional Amounts under the
   Indenture. In addition, under certain conditions, the Issuer may, at its
   option and at any time, elect to have the obligations of Bermuda Holdings and
   its Subsidiaries released with respect to certain covenants that are
   described in the Indenture ("covenant defeasance") and thereafter any
   omission to comply with such obligations shall not constitute a Default or an
   Event of Default with respect to the Senior Notes. In the event covenant
   defeasance occurs, certain events (not including non-payment, bankruptcy,
   receivership, rehabilitation and insolvency events) described under "--Events
   of Default and Remedies" will no longer constitute an Event of Default with
   respect to the Senior Notes.

     In order to exercise either defeasance or covenant defeasance: (i) the
   Issuer or Bermuda Holdings must irrevocably deposit with the Trustee, in
   trust, for the benefit of the holders of the Senior Notes, cash in U.S.
   dollars, U.S. Government Obligations, or a combination thereof, in such
   amounts as will be sufficient, in the opinion of a nationally recognized firm
   of independent public accountants, to pay the principal of, premium, if any,
   and interest on the outstanding Senior Notes; (ii) in the case of defeasance,
   the Issuer shall have delivered to the Trustee an opinion of counsel in the
   United States reasonably acceptable to the Trustee confirming that: (a) the
   Issuer has received from, or there has been published by, the Internal
   Revenue Service a ruling; or (b) since the date of the Indenture, there has
   been a change in the applicable federal income tax law, in either case to the
   effect that, and based thereon such opinion of counsel shall confirm that,
   the holders of the outstanding Senior Notes will not recognize income, gain
   or loss for federal income tax purposes as a result of such defeasance and
   will be subject to federal income tax on the same amounts, in the same manner
   and at the same times as would have been the case if such defeasance had not
   occurred; (iii) in the case of covenant defeasance, the Issuer shall have
   delivered to the Trustee an opinion of counsel in the United States
   reasonably acceptable to the Trustee confirming that the holders of the
   outstanding Senior Notes will not recognize income, gain or loss for federal
   income tax purposes as a result of such covenant defeasance and will be
   subject to federal income tax on the same amounts, in the same manner and at
   the same times as would have been the case if such covenant defeasance had
   not occurred; (iv) no Default or Event of Default shall have occurred and be
   continuing on the date of such deposit or insofar as Events of Default from
   bankruptcy or insolvency events are concerned, at any time in the period
   ending on the 91st day after the date of deposit; (v) such defeasance or
   covenant defeasance shall not result in a breach or violation of, or
   constitute a default under the Indenture, or any other material agreement or
   instrument to which Bermuda Holdings is a party or by which Bermuda Holdings
   is bound, (vi) the Issuer shall have delivered to the Trustee an opinion of
   counsel to the effect that after the 91st day following the deposit, the
   trust funds will not be subject to the effect of any applicable bankruptcy,
   insolvency, reorganization or similar laws affecting creditors' rights
   generally; (vii) the Issuer shall have delivered to the Trustee an officers'
   certificate stating that the deposit was not made by the Issuer or Bermuda
   Holdings with the intent of preferring the holders of Senior Notes over the
   other creditors of the Issuer or Bermuda Holdings or with the intent of
   defeating, hindering, delaying or defrauding creditors of the Issuer or
   Bermuda Holdings or others; and (viii) the Issuer shall have delivered to the
   Trustee an officers' certificate and an opinion of counsel, each stating that
   all conditions precedent provided for relating to either the defeasance or
   the covenant defeasance, as the case may be, have been complied with.

   Amendment, Supplement and Waiver

     The Indenture provides that the consent of holders of a majority in
   outstanding aggregate principal amount of Senior Notes will be required with
   respect to amendments which do not affect the payment terms of the Senior
   Notes or the amount of Senior Notes whose holders must consent to any
   amendment or the relative ranking of the Senior Notes. The latter amendments
   may only be made with the consent of each such Senior Note holder.

     With the consent of the holders of not less than a majority in principal
   amount of the outstanding Senior Notes (including consents obtained in
   connection with a tender offer or exchange offer for the Senior Notes), the
   Issuer and Bermuda Holdings, each when authorized by a board resolution, and
   the Trustee may enter into one or more supplemental indentures for the
   purpose of adding any provisions to or changing in any manner the rights of
   the holders under the Indenture or of waiving or modifying in any manner the
   rights of the holders under the Indenture; provided, however, that no such
   supplemental indenture, amendment or waiver shall without the consent of the
   holder of each outstanding Senior Note affected thereby: (a) change the
   Stated Maturity or the principal of, or any installment of interest on, or
   change the obligation of the Issuer or Bermuda Holdings to pay any Additional
   Amount with respect to, any Senior Note or reduce the principal amount
   thereof or the rate of interest thereon or any provisions relating to the
   redemption price of the Senior Notes or the periods during which redemption
   may be effected, or change the coin or currency in which the principal of any
   Senior Note or any premium or the interest thereon is payable, or impair the
   right to institute suit for the enforcement of any such payment after the
   Stated

                                      30
<PAGE>
 
   Maturity thereof (or, in the case of redemption, on or after the redemption
   date); or (b) reduce the percentage in principal amount of the outstanding
   Senior Notes, the consent of whose holders is required for any such
   supplemental indenture or the consent of whose holders is required for any
   waiver (of compliance with certain provisions of the Indenture or certain
   defaults and their consequences) provided for in the Indenture; or (c) modify
   any of the provisions of the Indenture relating to amendments or waivers of
   payment or covenant defaults, except to increase any such percentage or to
   provide that certain other provisions of the Indenture cannot be modified or
   waived without the consent of the holder of each Senior Note affected
   thereby.

     Notwithstanding the foregoing, without the consent of any holder of Senior
   Notes, the Issuer, Bermuda Holdings and the Trustee may amend or supplement
   the Indenture or the Senior Notes: (i) to cure any ambiguity or to correct
   any provision in the Indenture which may be defective or inconsistent with
   any other provision therein; or (ii) to provide for Definitive Senior Notes
   in addition to or in place of Book-Entry Interests; or (iii) to provide for
   the assumption of Bermuda Holdings' obligations to holders of the Senior
   Notes in the case of a merger or consolidation; or (iv) to secure the Senior
   Notes pursuant to the requirements of the provisions described under "--
   Merger, Consolidation or Sale of Assets" or "--Liens," or otherwise; or (v)
   to comply with the requirements of the Commission in order to maintain the
   qualification of the Indenture under the Trust Indenture Act, as contemplated
   by the Indenture or otherwise; or (vi) to evidence and provide the acceptance
   of the appointment of a successor Trustee thereunder; or (vii) to make any
   other change that would provide any additional rights or benefits to the
   holders or that does not adversely affect the legal rights of any holder
   under the Indenture or the Senior Notes.

   Concerning the Trustee

     The Indenture contains certain limitations on the rights of the Trustee,
   should it become a creditor of the Issuer or Bermuda Holdings, to obtain
   payment of claims in certain cases or to realize on certain property received
   in respect of any such claim as security or otherwise. The Trustee is
   permitted to engage in other transactions; however, if it acquires any
   conflicting interest it must eliminate such conflict within 90 days, apply to
   the Commission for permission to continue or resign.

     The holders of a majority in principal amount of the outstanding Senior
   Notes will have the right to direct the time, method and place of conducting
   any proceeding for exercising any remedy available to the Trustee, subject to
   certain exceptions. The Indenture provides that in case an Event of Default
   shall occur (which shall not be cured), the Trustee will be required, in the
   exercise of its power, to use the degree of care of a prudent man in the
   conduct of his own affairs. Subject to such provisions, the Trustee will be
   under no obligation to exercise any of its rights or powers under the
   Indenture at the request of any holder of Senior Notes, unless such holder
   shall have offered to the Trustee security and indemnity satisfactory to it
   against any loss, liability or expense.

   Certain Definitions

   Subsidiary shall be deemed to be incurred by a Restricted Subsidiary of
   Bermuda Holdings as of such date. The Board of Directors of Bermuda Holdings
   may at any time designate any Unrestricted Subsidiary to be a Restricted
   Subsidiary; provided that such designation shall be deemed to be an

                      DESCRIPTION OF DEPOSITARY AGREEMENT

   General

      All Exchange Notes underlying the Book-Entry Interests will be represented
   by one or more Global Notes, will be issued in a denomination equal to the
   aggregate principal amount of the sum of outstanding Old Notes properly
   tendered pursuant to the terms of the Exchange Offer, and will be deposited
   with the Custodian pursuant to the terms of the Depositary Agreement.

      With respect to such Global Notes issued, the Depositary will issue a
   receipt representing a 100% interest in the underlying Global Note (the
   "Exchange Global Receipt", and together with global receipts issued in
   respect of Old Notes not exchanged pursuant to the Exchange Offer, the
   "Global Receipts"), which will be delivered to and registered in the name of
   DTC or its nominee.

     Ownership of Book-Entry Interests is limited to Persons that have accounts
   with DTC ("participants") or Persons that may hold interests through
   participants.

     Procedures with respect to the ownership of Book-Entry Interests are set
   forth below. Unless and until the Book-Entry Interests representing the
   Exchange Global Receipts are exchanged for Definitive Senior Notes, the
   depositary interest held by DTC may not be transferred except as a whole by
   DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of
   DTC or by DTC or any such nominee to a successor of DTC or a nominee of such
   successor.

     So long as the Custodian, or its nominee, is the holder of the Global Notes
   underlying Book-Entry Interests, the Custodian or such nominee, as the case
   may be, will be considered the sole holder of such Exchange Global Note for
   all purposes under the Indenture. Except as set forth below under "--Issuance
   of Definitive Senior Notes," participants or Persons that may hold Book-Entry
   Interests through participants will not be entitled to have Senior Notes
   registered in their names, will not receive or be entitled to receive
   physical delivery of Definitive Senior Notes and will not be considered the
   owners or holders thereof under the Indenture. Accordingly, each Person
   holding a Book-Entry Interest must rely on the procedures of the Custodian,
   the Depositary and DTC and, in addition, if such Person is not a participant
   in DTC, on the procedures of the participant through which such Person owns
   its interest to exercise any rights and obligations of a holder under the
   Indenture. See "--Action by Holders of Book-Entry Interests."


   Payments on Global Note

     Payment of any amounts in respect of the Global Notes, as long as it is
   held by the Custodian, will be made to or by the order of the Custodian, as
   the bearer thereof. The Custodian will distribute all such payments received
   by it to the Depositary. The Depositary will distribute all such payments
   received by it to DTC, or its nominee, which will distribute such payments to
   its participants. All such payments will be distributed without deduction or
   withholding for any taxes, assessments

                                      35
<PAGE>
 
   or other governmental charges of whatever nature except as may be required by
   law. If any such deduction or withholding is required to be made under the
   provisions of any applicable law or regulation, then, except as provided in
   "Description of Exchange Notes--Payment of Additional Amounts," such
   additional amounts will be paid by the Issuer and Bermuda Holdings to or for
   the order of the Custodian as may be necessary in order that the net amounts
   received by a holder of Book-Entry Interests after such deduction or
   withholding shall be not less than the amounts which such holder would
   otherwise have received in respect of such Book-Entry Interests absent such
   withholding or deduction. DTC, upon receipt of any payment, will promptly
   credit participants' accounts with payments in amounts proportionate to their
   respective ownership of Book-Entry Interests, as shown on the records of DTC.
   The Issuer expects that payments by participants to holders of Book-Entry
   Interests held through such participants will be governed by standing
   customer instructions and customary practices, as is now the case with the
   securities held for the accounts of customers in bearer form or registered in
   "street name," and will be the responsibility of such participants. None of
   the Issuer, Bermuda Holdings, the Trustee or any other agent of the Issuer,
   Bermuda Holdings or the Trustee will have any responsibility or liability for
   any aspect of the records relating to or payments made on account of a
   participant's Book-Entry Interests or for maintaining, supervising or
   reviewing any records relating to a participant's Book-Entry Interests.

     DTC has advised the Issuer as follows: DTC is a limited-purpose trust
   company organized under the New York Banking Law, a "banking organization"
   within the meaning of the New York Banking Law, a member of the Federal
   Reserve System, a "clearing corporation" within the meaning of the New York
   Uniform Commercial Code, and a "clearing agency" registered pursuant to the
   provisions of Section 17A of the Exchange Act. DTC was created to hold
   securities of its participants and to facilitate the clearance and settlement
   of transactions among its participants in such securities through electronic
   book-entry exchanges in accounts of the participants, thereby eliminating the
   need for physical movement of securities certificates. DTC participants
   include securities brokers and dealers (including the Underwriters), banks,
   trust companies, clearing corporations and certain other organizations, some
   of whom (and/or their representatives) own DTC. Access to DTC book-entry
   system is also available to others, such as banks, brokers, dealers and trust
   companies that clear through or maintain a custodial relationship with a
   participant, either directly or indirectly.

     Although DTC is expected to follow the foregoing procedures in order to
   facilitate transfers of Book-Entry Interests among participants of DTC, DTC
   is under no obligation to perform or continue to perform such procedures, and
   such procedures may be discontinued at any time. Neither the Issuer, Bermuda
   Holdings nor the Trustee will have any responsibility for the performance by
   DTC of obligations under the rules and procedure governing their operations.

     Upon the issuance by the Depositary of the Exchange Global Receipts to DTC,
   DTC will credit, on its book-entry registration and transfer system, the
   participants' accounts with the respective interest beneficially owned by
   such participants. Ownership of Book-Entry Interests will be shown on, and
   the transfer of such interests will be effected only through, records
   maintained by DTC (with respect to interests of participants) and on the
   records of participants (with respect to interests of Persons holding through
   participants). The laws of some states may require that certain purchasers of
   securities take physical delivery of such securities in definitive form. Such
   limits and such laws may impair the ability to own, transfer or pledge Book-
   Entry Interests.

     The Issuer understands that under existing industry practices, if either
   the Issuer or the Trustee requests any action of holders of Book-Entry
   Interests or if a holder of a Book-Entry Interest desires to give or take any
   action that a holder of Senior Notes is entitled to give or take under the
   Indenture, DTC would authorize the participants holding the relevant Book-
   Entry Interests to give or take such action, and such participants would
   authorize beneficial owners owning through such participants to give or take
   such action or would otherwise act upon the instructions of beneficial owners
   holding through them.

   Redemption or Repurchase

     In the event the Global Notes (or portions thereof) are redeemed or
   repurchased, the Custodian will deliver all amounts received by it in respect
   of the redemption or repurchase to the Depositary. The Depositary will
   deliver all amounts received by it in respect of the redemption or repurchase
   of the Global Notes to DTC. The redemption or repurchase price paid in
   connection with the redemption or repurchase of Book-Entry Interests will be
   equal to the amount received by the Depositary in connection with the
   redemption or repurchase of the Global Notes (or portions thereof). For any
   redemptions of the Global Notes in part, selection of Book-Entry Interests to
   be redeemed will be made by DTC on a pro rata basis, by lot or by such other
   method as DTC deems fair and appropriate, and in compliance with the
   requirements of the principal national securities exchange, if any, on which
   the Senior Notes are listed, or, if the Senior Notes are not so listed, on a
   pro rata basis, by lot

                                      36
<PAGE>
 
   or by such method as DTC shall deem fair and appropriate; provided that no
   beneficial interests of $1,000 principal amount at maturity or less shall be
   redeemed in part.

   Transfers

     All transfers of Book-Entry Interests will be recorded in accordance with
   the book-entry system maintained by DTC, pursuant to customary procedures
   established by DTC and its participants and will be settled in same-day
   funds.

   Issuance of Definitive Senior Notes

     Holders of Book-Entry Interests will receive Definitive Senior Notes if (i)
   DTC notifies the Issuer and the Depositary that it is unwilling or unable to
   continue as holder of the Global Receipts or ceases to be a clearing agency
   registered under the Exchange Act and, in either case, a successor to DTC
   registered as a clearing agency under the Exchange Act is not appointed by
   the Issuer within 90 days of such notification, (ii) either the Depositary or
   the Custodian, as the case may be, notifies the Trustee and the Issuer that
   it is unwilling or unable to continue as Depositary or Custodian,
   respectively, and a successor Depositary or Custodian, as the case may be, is
   not appointed by the Issuer within 90 days of such notification, or (iii) the
   Issuer determines that Definitive Senior Notes shall be issued. Any
   Definitive Senior Notes issued in exchange for Book-Entry Interests will be
   registered in such name or names as the Custodian shall instruct the Trustee
   based on the instructions of DTC. It is expected that such instructions will
   be based upon directions received by DTC from participants with respect to
   ownership of Book-Entry Interests.

     In addition to the foregoing, holders of Book-Entry Interests will at any
   time on or after the occurrence of an Event of Default be entitled to request
   and receive Definitive Senior Notes. Such Definitive Senior Notes will be
   issued to and registered in the name of, or as directed by, such holders only
   upon the request in writing by the Depositary (based upon the instructions of
   DTC).

     HOLDERS OF BOOK-ENTRY INTERESTS SHOULD BE AWARE THAT, UNDER CURRENT U.K.
   TAX LAW, UPON THE ISSUANCE OF DEFINITIVE SENIOR NOTES TO A HOLDER, SUCH
   HOLDER WILL BECOME SUBJECT TO U.K. INCOME TAX (CURRENTLY 20%) TO BE WITHHELD
   ON ANY PAYMENTS OF INTEREST ON THE SENIOR NOTES AS SET FORTH UNDER "CERTAIN
   TAX CONSIDERATIONS--TAXATION OF U.S. HOLDERS OF THE SENIOR NOTES--UNITED
   KINGDOM." IF SUCH DEFINITIVE SENIOR NOTES ARE ISSUED PURSUANT TO THE REQUEST
   OF A HOLDER OF BOOK-ENTRY INTERESTS FOLLOWING AN EVENT OF DEFAULT, NEITHER
   THE ISSUER NOR BERMUDA HOLDINGS WILL BE OBLIGATED TO PAY ANY ADDITIONAL
   AMOUNTS WITH RESPECT TO SUCH SENIOR NOTES. However, U.S. holders of
   Definitive Senior Notes may be entitled to receive a refund of withheld
   amounts from the U.K. Inland Revenue in certain circumstances. See "Certain
   Tax Considerations--Taxation of U.S. Holders of the Senior Notes--United
   Kingdom." In addition, if a holder of Book-Entry Interests receives
   Definitive Senior Notes other than pursuant to its request, such holder will
   be entitled to receive Additional Amounts with respect to such Senior Notes.
   See "Description of Exchange Notes--Payment of Additional Amounts."

     Exchanges of Book-Entry Interests for Definitive Senior Notes shall be made
   free of any fees of the Depositary to the holders of Book-Entry Interests;
   provided that the Issuer may require the payment of a sum sufficient to pay
   any tax, assessment, or other governmental charge.

   Action by Holders of Book-Entry Interests

     As soon as practicable after receipt by the Custodian of notice of any
   solicitation of consents or request for a waiver or other action by the
   holders of Book-Entry Interests, the Custodian shall direct the Depositary to
   mail to DTC a notice containing (a) such information as is contained in such
   notice, (b) a statement that at the close of business on a specified record
   date DTC will be entitled to instruct the Depositary as to the consent,
   waiver or other action, if any, pertaining to the Book-Entry Interests, and
   (c) a statement as to the manner in which such instructions may be given.
   Upon the written request of DTC, the Depositary shall endeavor insofar as
   practicable to take such action regarding the requested consent, waiver or
   other action in respect of the Book-Entry Interests in accordance with any
   instructions set forth in such request. DTC is expected to follow the
   procedures described under "--General" above with respect to soliciting
   instructions from its participants. Neither the Depositary nor the Custodian
   will exercise any discretion in the granting of consents or waivers or the
   taking of any other action relating to the Depositary Agreement or the
   Indenture.

                                      37
<PAGE>
 
   Reports

     The Depositary will promptly send to DTC a copy of any notices, reports and
   other communications received from the Issuer which are received by the
   Custodian as holder of the Global Note.

   The Depositary and Custodian

     The Chase Manhattan Bank is the Depositary for the Global Note. The address
   of the Depositary is 450 West 33rd Street, 15th Floor, New York, New York
   10001. Chase Manhattan Bank Luxembourg S.A. will be the Custodian for the
   Exchange Global Receipt. The address of the Custodian is 5 rue Plaetis L-
   2338, Luxembourg.

   Action by Depositary and Custodian

     Upon the occurrence of a default with respect to the Global Note, or in
   connection with any other right of the holder of the Global Note under the
   Indenture or the Depositary Agreement, if requested in writing by DTC in
   respect thereof, the Depositary and the Custodian will take any such action
   as shall be requested in such notice; provided that the Depositary and the
   Custodian have been offered reasonable security or indemnity against the
   costs, expenses and liabilities that might be incurred by them in complying
   with such request.

     Neither the Depositary nor the Custodian will exercise any discretion in
   the taking of any such action.

   Charges of Depositary and Custodian

     The Issuer and Bermuda Holdings have agreed to pay all charges of the
   Depositary and the Custodian under the Depositary Agreement. The Issuer and
   Bermuda Holdings have also agreed to indemnify the Depositary and the
   Custodian against certain liabilities incurred by it under the Depositary
   Agreement.

   Amendment and Termination

     The Depositary Agreement may be amended by agreement among the Issuer,
   Bermuda Holdings, the Custodian and the Depositary. The consent of DTC shall
   not be required in connection with any amendment to the Depositary Agreement:
   (i) to cure any defect, omission, inconsistency or ambiguity in the
   Depositary Agreement; (ii) to add to the covenants and agreements of the
   Depositary or the Custodian, the Issuer and Bermuda Holdings; (iii) to
   effectuate the assignment of the Depositary's or the Custodian's rights and
   duties to a qualified successor; (iv) to comply with the Securities Act, the
   Exchange Act or the U.S. Investment Company Act of 1940, as amended; or (v)
   to modify, alter, amend or supplement the Depositary Agreement in any other
   manner that, in the opinion of counsel acceptable to the Issuer and the
   Depositary, is not adverse to DTC or the owners of Book-Entry Interests.
   Except as set forth above, no amendment that adversely affects DTC may be
   made to the Depositary Agreement or the Book-Entry Interests without the
   consent of DTC.

     The Depositary shall at any time at the direction of the Issuer or Bermuda
   Holdings terminate the Depositary Agreement by mailing a notice of such
   termination to DTC and requesting, on behalf of the Custodian in accordance
   with the Indenture, the issuance of Definitive Senior Notes to the persons
   and in the amounts as specified by DTC. Upon the issuance of Definitive
   Senior Notes in an aggregate principal amount equal to the aggregate
   principal amount of Senior Notes outstanding, the Depositary Agreement shall
   terminate. The Depositary Agreement may also be terminated upon the
   resignation of the Depositary or the Custodian if no successor depositary or
   custodian, as the case may be, has been appointed by the Issuer within 90
   days of the notification of such resignation as set forth under
   "--Resignation or Removal of Depositary or Custodian" below.

   Resignation or Removal of Depositary or Custodian

     The Depositary or Custodian may at any time resign as Depositary or
   Custodian by written notice delivered to each of the Issuer and the Trustee,
   such resignation to take effect upon the appointment by the Issuer of a
   successor depositary or custodian (approved, in the case of a successor
   depositary, by the Trustee and DTC and, in the case of a successor custodian,
   by the Depositary, none of which shall unreasonably withhold such approval)
   and such successor's acceptance of such appointment. If at the end of 90 days
   after delivery of such notice, no successor depositary or custodian has been
   appointed and approved, and has accepted such appointment, the resigning
   Depositary or Custodian may terminate the Depositary Agreement.

                                      38
<PAGE>
 
   Obligations of Depositary and Custodian

     Except with respect to the payment of any amount received by it in respect
   of the Global Notes, neither the Depositary nor the Custodian will assume any
   obligation or be subject to any liability under the Depositary Agreement,
   other than by reason of bad faith or negligence in the performance of its
   respective duties under the Depositary Agreement.


                            DESCRIPTION OF OLD NOTES


     The terms of the Exchange Notes are identical in all material respects to
   the terms of the Old Notes, except that (i) the offer and sale of the
   Exchange Notes have been registered under the Securities Act and therefore
   the Exchange Notes are not subject to certain restrictions on transfer
   applicable to the Old Notes, will not contain legends relating thereto and
   will not be entitled to registration rights or other rights under the
   Registration Rights Agreement, and (ii) the Exchange Notes will not provide
   for any increase in the interest rate thereon, which rights and provision
   will terminate as to all of the Senior Notes upon the consummation of the
   Exchange Offer. In addition, the Old Notes and the Exchange Notes will
   constitute a single series of debt securities under the Indenture. See
   "Description of Exchange Notes--General."


                               THE EXCHANGE OFFER

     The Issuer and Bermuda Holdings entered into the Registration Rights
   Agreement dated as of August 20, 1997 (the "Registration Rights Agreement")
   with Donaldson, Lufkin & Jenrette Securities Corporation, as Initial
   Purchaser, pursuant to which the Issuer and Bermuda Holdings agreed, for the
   benefit of the holders of the Old Notes, at the cost of the Issuer and
   Bermuda Holdings, to use commercially reasonable efforts to file and cause to
   become effective a registration statement with respect to an exchange offer
   for exchange notes with terms identical in all material respects to the Old
   Notes, except as described under "Description of Old Notes." In the event
   that applicable interpretations of the Commission do not permit the Issuer
   and Bermuda Holdings to effect the Exchange Offer, or under certain other
   circumstances, the Issuer and Bermuda Holdings agreed, for the benefit of the
   Holders of the Old Notes, at the cost of the Issuer and Bermuda Holdings, to
   use commercially reasonable efforts to cause to become effective a shelf
   registration statement (the "Shelf Registration Statement") with respect to
   resales of the Senior Notes and to keep such registration statement effective
   until August 26, 2000 or such earlier time when the Senior Notes have been
   sold pursuant to such Shelf Registration Statement.

     The Old Notes provide that, in the event the Exchange Offer is not
   consummated or a Shelf Registration Statement is not declared effective on or
   prior to February 26, 1998, then the annual interest rate borne by the Old
   Notes shall be increased to 7.45%. If the Exchange Offer is not consummated
   or a Shelf Registration Statement is not declared effective by May 26, 1998,
   then the annual interest rate borne by the Old Notes shall be increased to
   7.7%. Upon consummation of the Exchange Offer or the effectiveness of such
   Shelf Registration Statement, the interest rate borne by the Old Notes will
   return to 7.2%.

     The Exchange Offer is not being made to, nor will the Issuer or Bermuda
   Holdings accept tenders for exchange from, holders of Old Notes in any
   jurisdiction in which the Exchange Offer or the acceptance thereof would not
   be in compliance with the securities or blue sky laws of such jurisdiction.

   Terms of the Exchange Offer; Period for Tendering Old Notes
    
     Upon the terms and subject to the conditions set forth in this Prospectus
   and in the accompanying Letter of Transmittal (which together constitute the
   Exchange Offer), the Issuer will accept for exchange Old Notes which are
   properly tendered on or prior to the Expiration Date and not withdrawn as
   permitted below. For each $1,000 principal amount of Old Notes surrendered to
   the Issuer pursuant to the Exchange Offer, the Holder of such Old Note will
   receive an Exchange Note having a principal amount equal to that of the
   surrendered Old Note. The Issuer will keep the Exchange Offer open for not
   less than 20 business days (or longer if required by applicable law) after
   the date notice of the Exchange Offer is mailed to the Holders of the Old
   Notes. As used herein, the term "Expiration Date" means 5:00 p.m., New York
   City time, on December 3, 1997; provided, however, that if the Issuer and
   Bermuda Holdings, in their sole discretion, have extended the period of time
   for which the Exchange Offer is open, the term "Expiration Date" means the
   latest time and date to which the Exchange Offer is extended.      

     As of the date of this Prospectus, $75.0 million in aggregate principal
   amount of the Old Notes were outstanding. The Exchange Offer is not
   conditioned upon any minimum principal amount of Old Notes being tendered.
   This Prospectus,

                                      39
<PAGE>
 
   together with the Letter of Transmittal, is first being sent on or about the
   date set forth on the cover page to all holders of Old Notes at the addresses
   set forth in the security register with respect to Old Notes maintained by
   the Trustee. The Issuer's obligations to accept Old Notes for exchange
   pursuant to the Exchange Offer is subject to certain conditions as set forth
   under "--Certain Conditions to the Exchange Offer."

     The Issuer and Bermuda Holdings expressly reserve the right, at any time or
   from time to time, to extend the period of time during which the Exchange
   Offer is open, and thereby delay acceptance of any Old Notes, by giving oral
   or written notice of such extension to the Exchange Agent and notice of such
   extension to the holders of Old Notes as described below. During any such
   extension, all Old Notes previously tendered will be retained by the Issuer
   or Bermuda Holdings, subject to the rights of holders of Old Notes to
   withdraw their tendered Old Notes as specified in "--Withdrawal Rights." Any
   Old Notes not accepted for exchange for any reason will be returned without
   expense to the tendering holder thereof as promptly as practicable after the
   expiration or termination of the Exchange Offer.

     The Issuer and Bermuda Holdings expressly reserve the right to amend or
   terminate the Exchange Offer, and not to accept for exchange any Old Notes
   not theretofore accepted for exchange, upon the occurrence of any of the
   conditions of the Exchange Offer specified below under "--Certain Conditions
   to the Exchange Offer." The Issuer or Bermuda Holdings will give oral or
   written notice of any extension, amendment, non-acceptance or termination to
   the holders of the Old Notes as promptly as practicable, such notice in the
   case of any extension to be issued by means of a press release or other
   public announcement no later than 9:00 a.m., New York City time, on the next
   business day after the previously scheduled Expiration Date. Without limiting
   the manner in which the Issuer or Bermuda Holdings may choose to make any
   public announcement and subject to applicable law, neither the Issuer nor
   Bermuda Holdings shall have any obligation to publish, advertise or otherwise
   communicate any such public announcement other than by issuing a release to
   the Dow Jones News Service.

     Holders of Old Notes do not have any appraisal or dissenters' rights in
   connection with the Exchange Offer. Old Notes which are not tendered for
   exchange or are tendered but not accepted in connection with the Exchange
   Offer will remain outstanding, will be entitled to the benefits of the
   Indenture and continue to accrue interest, but will not be entitled to any
   further registration rights under the Registration Rights Agreement. The
   Issuer and Bermuda Holdings intend to conduct the Exchange Offer in
   accordance to the applicable requirements of the Exchange Act and the rules
   and regulations of the Commission thereunder.

   Procedures for Tendering Old Notes
    
     The tender to the Issuer of Old Notes by a Holder thereof as set forth
   below and the acceptance thereof by the Issuer will constitute a binding
   agreement between the tendering holder, the Issuer and Bermuda Holdings upon
   the terms and subject to the conditions set forth in this Prospectus and in
   the accompanying Letter of Transmittal. Any beneficial owner whose Old Notes
   are registered in the name of a broker, dealer, commercial bank, trust
   company or nominee and who wishes to tender should contact such registered
   holder promptly and instruct such registered holder to tender on his behalf.
   A holder who wishes to tender Old Notes for exchange pursuant to the Exchange
   Offer must transmit a properly completed and duly executed Letter of
   Transmittal, including all other documents required by such Letter of
   Transmittal, to the Exchange Agent at the address set forth below under
   "Exchange Agent" on or prior to the Expiration Date. In addition, (i) a
   timely confirmation of a book-entry transfer (a "Book-Entry Confirmation") of
   such Old Notes, if such procedure is available, into the Exchange Agent's
   account at DTC pursuant to the procedure for book-entry transfer described
   below, must be received by the Exchange Agent prior to the Expiration Date or
   (ii) the holder must comply with the guaranteed delivery procedures described
   below under "--Guaranteed Delivery Procedures." THE METHOD OF DELIVERY OF
   LETTERS OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION
   AND RISK OF THE TENDERING HOLDER. IF SUCH DELIVERY IS BY MAIL, IT IS
   RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT
   REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE
   TIMELY DELIVERY. NO LETTERS OF TRANSMITTAL OR ANY OTHER REQUIRED DOCUMENTS
   SHOULD BE SENT TO THE ISSUER OR BERMUDA HOLDINGS. Delivery of all documents
   must be made to the Exchange Agent at its address set forth below. Holders
   may also request their respective brokers, dealers, commercial banks, trust
   companies or nominees to effect such tender for such Holders.     

     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
   case may be, must be guaranteed unless the Old Notes surrendered for exchange
   pursuant thereto are tendered for the account of an Eligible Institution (as
   defined below). In the event that signatures on a Letter of Transmittal or a
   notice of withdrawal, as the case may be, are required to be

                                      40
<PAGE>
 
   guaranteed, such guarantees must be by a firm which is a member of a
   registered national securities exchange or a member of the National
   Association of Securities Dealers, Inc. or by a commercial bank or trust
   company having an office or correspondent in the United States (collectively,
   "Eligible Institutions"). If a Book-Entry Confirmation indicates that
   ownership of the Old Notes is in the name of a person other than the person
   signing the Letter of Transmittal, the Exchange Agent must receive a written
   instrument or instruments of transfer or exchange, in satisfactory form as
   determined by the Issuer and Bermuda Holdings in their sole discretion, duly
   executed by the owner as evidenced by the Book-Entry Confirmation with the
   signature thereon guaranteed by an Eligible Institution.

     All questions as to the validity, form, eligibility (including time of
   receipt) and acceptance of Old Notes tendered for exchange will be determined
   by the Issuer and Bermuda Holdings in their sole discretion, which
   determination shall be final and binding. The Issuer and Bermuda Holdings
   reserve the absolute right to reject any and all tenders of any particular
   Old Notes not properly tendered or to not accept any particular Old Notes
   which acceptance might, in the judgment of the Issuer and Bermuda Holdings or
   their counsel, be unlawful. The Issuer and Bermuda Holdings also reserve the
   absolute right to waive any defects or irregularities or conditions of the
   Exchange Offer as to any particular Old Notes either before or after the
   Expiration Date (including the right to waive the ineligibility of any holder
   who seeks to tender Old Notes in the Exchange Offer). The interpretation of
   the terms and conditions of the Exchange Offer as to any particular Old Notes
   either before or after the Expiration Date (including the Letter of
   Transmittal and the instructions thereto) by the Issuer and Bermuda Holdings
   shall be final and binding on all parties. Unless waived, any defects or
   irregularities in connection with the tender of Old Notes for exchange must
   be cured within such reasonable period of time as the Issuer or Bermuda
   Holdings shall determine. Neither the Issuer, Bermuda Holdings, the Exchange
   Agent nor any other person shall be under any duty to give notification of
   any defect or irregularity with respect to any tender of Old Notes for
   exchange, nor shall any of them incur any liability for failure to give such
   notification.

     If the Letter of Transmittal is signed by a person or persons other than
   the owner as evidenced by the Book-Entry Confirmation, such Letter of
   Transmittal must be accompanied by an endorsement or appropriate powers of
   attorney, in either case signed exactly as the name or names of the owner as
   evidenced by the Book-Entry Confirmation. Signatures on such powers of
   attorney must be guaranteed by an Eligible Institution.

     If the Letter of Transmittal or powers of attorney are signed by trustees,
   executors, administrators, guardians, attorneys-in-fact, officers or
   corporations or others acting in a fiduciary or representative capacity, such
   person should so indicate when signing and, unless waived by the Issuer or
   Bermuda Holdings, proper evidence satisfactory to the Issuer and Bermuda
   Holdings of its authority to so act must be submitted.

     By executing, or otherwise becoming bound by, the Letter of Transmittal,
   each holder of the Old Notes (other than certain specified holders) will
   represent that (i) it is not an affiliate of the Issuer or Bermuda Holdings,
   (ii) any Exchange Notes to be received by it were acquired in the ordinary
   course of its business, and (iii) it has no arrangement or understanding with
   any person to participate in a distribution (within the meaning of the
   Securities Act) of the Exchange Notes. If the tendering holder is a broker-
   dealer that will receive Exchange Notes for its own account in exchange for
   Old Notes that were acquired as a result of market-making activities or other
   trading activities, it will be required to acknowledge that it acquired the
   Old Notes for its account as the result of market-making activities or other
   trading activities and must agree that it will deliver a prospectus in
   connection with any resale of such Exchange Notes. A broker-dealer that
   acquired Old Notes in a transaction other than as part of its market-making
   or other trading activities will not be able to participate in the Exchange
   Offer. See "--Resales of the Exchange Notes."

   Acceptance of Old Notes for Exchange

     Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
   the Issuer will accept, promptly after the Expiration Date, all Old Notes
   properly tendered and will issue the Exchange Notes promptly after acceptance
   of the Old Notes. See "--Certain Conditions to the Exchange Offer." For
   purposes of the Exchange Offer, the Issuer shall be deemed to have accepted
   properly tendered Old Notes for exchange when, as and if the Issuer has given
   oral or written notice thereof to the Exchange Agent.

     In all cases, issuance of Exchange Notes for Old Notes that are accepted
   for exchange pursuant to the Exchange Offer will be made only after timely
   receipt by the Exchange Agent of a timely Book-Entry Confirmation of such Old
   Notes into the Exchange Agent's account at DTC, a properly completed and duly
   executed Letter of Transmittal and all other required documents. If any
   tendered Old Notes are not accepted for any reason set forth in the terms and
   conditions of the Exchange Offer or Old Notes are submitted for a greater
   principal amount than the holder desires to exchange, such unaccepted or non-

                                      41
<PAGE>
 
   exchanged Old Notes will be credited to an account maintained with DTC as
   promptly as practicable after the expiration or termination of the Exchange
   Offer.

   Interest on the Exchange Notes

     Each Exchange Note will bear interest from August 26, 1997, the date of
   issuance of the Old Notes. Holders of the Old Notes whose Old Notes are
   accepted for exchange will not receive accrued interest on such Old Notes
   from and after August 26, 1997.

   Book-Entry Transfer

     The Exchange Agent will make a request to establish an account with respect
   to the Old Notes at DTC for purposes of the Exchange Offer promptly after the
   date of this Prospectus. Any financial institution that is a participant in
   DTC's systems may make book-entry delivery of Old Notes by causing DTC to
   transfer such Old Notes into the Exchange Agent's account in accordance with
   DTC's Automated Tender Offer Program ("ATOP") procedures for transfer.
   However, the exchange for the Old Notes so tendered will only be made after
   timely confirmation of such book-entry transfer of Old Notes into the
   Exchange Agent's account, and timely receipt by the Exchange Agent of an
   Agent's Message (as such term is defined in the next sentence) and any other
   documents required by the Letter of Transmittal. The term "Agent's Message"
   means a message, transmitted by DTC and received by the Exchange Agent and
   forming a part of a Book-Entry Confirmation, which states that DTC has
   received an express acknowledgment from a participant tendering Old Notes
   that are the subject of such Book-Entry Confirmation that such participant
   has received and agrees to be bound by the terms of the Letter of
   Transmittal, and that the Issuer or Bermuda Holdings may enforce such
   agreement against such participant. Although delivery of Old Notes may be
   effected through book-entry transfer into the Exchange Agent's account at
   DTC, the Letter of Transmittal (or facsimile thereof), properly completed and
   duly executed, with any required signature guarantees and any other required
   documents, must in any case be delivered to and received by the Exchange
   Agent at its address set forth under "--Exchange Agent" prior to the
   Expiration Date, or the guaranteed delivery procedure set forth below must be
   complied with.

     DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH ITS PROCEDURES DOES NOT
   CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

   Guaranteed Delivery Procedures

     If the procedure for book-entry transfer cannot be completed on a timely
   basis, a tender may be effected if (i) the tender is made by or through an
   Eligible Institution, (ii) prior to the Expiration Date, the Exchange Agent
   receives from such Eligible Institution a properly completed and duly
   executed Letter of Transmittal (or a facsimile thereof) and Notice of
   Guaranteed Delivery, substantially in the form provided by the Issuer and
   Bermuda Holdings (by telegram, telex, facsimile transmission, mail or hand
   delivery), setting forth the name and address of the holder of Old Notes and
   the amount of Old Notes tendered, stating that the tender is being made
   thereby and guaranteeing that within five New York Stock Exchange ("NYSE")
   trading days after the date of execution of the Notice of Guaranteed
   Delivery, a Book-Entry Confirmation and any other documents required by the
   Letter of Transmittal will be deposited by the Eligible Institution with the
   Exchange Agent, and (iii) the Book-Entry Confirmation, and all other
   documents required by the Letter of Transmittal, are received by the Exchange
   Agent within five NYSE trading days after the date of execution of the Notice
   of Guaranteed Delivery.

   Withdrawal Rights

     Tenders of Old Notes may be withdrawn at any time prior to the Expiration
   Date.
    
     For a withdrawal to be effective, a written notice of withdrawal must be
   received by the Exchange Agent by the Exchange Date at one of the addresses
   set forth below under "--Exchange Agent." Any such notice of withdrawal
   (which notice may be by telegram, telex, facsimile transmission or letter)
   must specify the name of the person having tendered the Old Notes to be
   withdrawn, the number of the account at DTC from which the Old Notes were
   tendered, the principal amount of the Old Notes to be withdrawn, and the name
   and number of the account at DTC to be credited with the withdrawn Old Notes,
   and otherwise comply with the procedures of such facility. All questions as
   to the validity, form and eligibility (including time of receipt) of such
   withdrawal notices will be determined by the Issuer and Bermuda Holdings,
   whose determination shall be final and binding on all parties. Any Old Notes
   so withdrawn will be deemed not to have been validly tendered for exchange
   for purposes of the Exchange Offer. Any Old Notes which have been tendered
   for exchange but which are not exchanged for any reason will be credited to
   an account maintained with DTC for the Old Notes as soon as practicable after
   withdrawal, rejection of tender or termination of the Exchange Offer.
   Properly withdrawn Old Notes may be retendered by     

                                      42
<PAGE>
 
    
   following one of the procedures described under "--Procedures for Tendering
   Old Notes" at any time prior to the Expiration Date.      

   Certain Conditions to the Exchange Offer

     Notwithstanding any other provisions of the Exchange Offer, neither the
   Issuer nor Bermuda Holdings shall be required to accept for exchange, or to
   issue Exchange Notes in exchange for, any Old Notes and may terminate or
   amend the Exchange Offer, if at any time before the acceptance of such Old
   Notes for exchange or the exchange of the Exchange Notes for such Old Notes,
   such acceptance or issuance would violate applicable law or any
   interpretation of the Staff of the Commission. Neither the Issuer or Bermuda
   Holdings has any obligation, and will not knowingly, permit acceptances of
   tenders of Old Notes from Affiliates of the Issuer or Bermuda Holdings or
   from any other holder or holders of Old Notes who are not eligible to
   participate in the Exchange Offer under applicable law or interpretations
   thereof by the Commission, or if the Exchange Notes to be received by such
   holder or holders of Old Notes in the Exchange Offer, upon receipt, will not
   be tradable by such holder without restriction under the Securities Act and
   the Exchange Act and without material restrictions under the blue sky or
   securities laws of substantially all of the states of the United States.

     The foregoing conditions are for the sole benefit of the Issuer and Bermuda
   Holdings and may be asserted by the Issuer and Bermuda Holdings regardless of
   the circumstances giving rise to any such condition. The failure by the
   Issuer and Bermuda Holdings at any time to exercise the foregoing rights
   shall not be deemed a waiver of any such right and each such right shall be
   deemed an ongoing right which may be asserted at any time and from time to
   time.

     In addition, neither the Issuer nor Bermuda Holdings will accept for
   exchange any Old Notes tendered, and no Exchange Notes will be issued in
   exchange for any such Old Notes, if at such time any stop order shall be
   threatened or in effect with respect to the Registration Statement of which
   this Prospectus constitutes a part or the qualification of the Indenture
   under the Trust Indenture Act.

   Exchange Agent

     The Chase Manhattan Bank has been appointed as the Exchange Agent for the
   Exchange Offer. All executed Letters of Transmittal should be directed to the
   Exchange Agent at one of the addresses set forth below. Questions and
   requests for assistance, requests for additional copies of this Prospectus or
   of the Letter of Transmittal and requests for Notices of Guaranteed Delivery
   should be directed to the Exchange Agent, addressed as follows:

                           450 West 33rd St.
                           15th Floor
                           New York, New York  10001

                              Confirm by Telephone:
                           (212) 946-3352

     DELIVERY TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE OR TRANSMISSION OF
   INSTRUCTIONS VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE DOES NOT CONSTITUTE
   A VALID DELIVERY.

   Fees and Expenses

     The principal solicitation is being made by mail; however, additional
   solicitation may be made by telegraph, telephone or in person by officers and
   regular employees of the Issuer, Bermuda Holdings and their affiliates. No
   additional compensation will be paid to any such officers and employees who
   engage in soliciting tenders. Neither the Issuer nor

                                      43
<PAGE>
 
   Bermuda Holdings will make any payment to brokers, dealers, or others
   soliciting acceptances of the Exchange Offer. The Issuer or Bermuda Holdings,
   however, will pay the Exchange Agent reasonably customary fees for its
   services and will reimburse it for its reasonable out-of-pocket expenses in
   connection therewith.
    
     The estimated cash expenses to be incurred in connection with the Exchange
   Offer will be paid by the Issuer and Bermuda Holdings and are estimated in
   the aggregate to be $210,000.      
                        
   Transfer Taxes

     Holders who tender their Old Notes for exchange will not be obligated to
   pay any transfer taxes in connection therewith.

   Resales of the Exchange Notes

     Under existing interpretations of the staff of the Division of Corporation
   Finance of the Commission contained in several no-action letters to third
   parties (including Exxon Capital Holdings Corporation (available May 13,
   1988), Morgan Stanley & Co. Incorporated (available June 5, 1991), K-III
   Communications Corporation (available May 14, 1993) and Shearman & Sterling
   (available July 2, 1993)), the Exchange Notes would in general be freely
   transferable after the Exchange Offer without further registration under the
   Securities Act. However, any purchaser of Old Notes who is an "affiliate" of
   the Issuer or Bermuda Holdings or who intends to participate in the Exchange
   Offer for the purpose of distributing the Exchange Notes or any broker-dealer
   who purchased Old Notes from the Issuer or Bermuda Holdings to resell
   pursuant to Rule 144A or any other available exception under the Securities
   Act (i) will not be able to rely on the interpretation of the staff of the
   Division of Corporation Finance of the Commission, (ii) will not be able to
   tender its Old Notes in the Exchange Offer and (iii) must comply with the
   registration and prospectus delivery requirements of the Securities Act in
   connection with any sale or transfer of the Old Notes unless such sale or
   transfer is made pursuant to an exemption from such requirements.

     By executing, or otherwise becoming bound by, the Letter of Transmittal
   each holder of the Old Notes (other than certain specified holders) will
   represent that (i) it is not an "affiliate" of the Issuer or Bermuda
   Holdings, (ii) any Exchange Notes to be received by it were acquired in the
   ordinary course of its business and (iii) it has no arrangement or
   understanding with any person to participate in the distribution (within the
   meaning of the Securities Act) of the Exchange Notes. In addition, in
   connection with any resales of Exchange Notes, any Participating Broker-
   Dealer who acquired the Exchange Notes for its own account as a result of
   market-making or other trading activities must acknowledge that it acquired
   the Old Notes for its own account as the result of market-making activities
   or other trading activities and must agree that it deliver a prospectus
   meeting the requirements of the Securities Act. A broker-dealer that acquired
   Existing Notes in a transaction other than as part of its market-making or
   other trading activities will not be able to participate in the Exchange
   Offer. The Letter of Transmittal states that by so acknowledging and by
   delivering a prospectus, a broker-dealer will not be deemed to admit that it
   is an "underwriter" within the meaning of the Securities Act. Based on the
   position taken by the staff of the Division of Corporation Finance of the
   Commission in the no-action letters referred to above, the Issuer believes
   that Participating Broker-Dealers may fulfill their prospectus delivery
   requirements with respect to the Exchange Notes received upon exchange of
   such Old Notes (other than Old Notes which represent an unsold allotment from
   the original sale of the Old Notes) with a prospectus meeting the
   requirements of the Securities Act, which may be a prospectus prepared for an
   exchange offer so long as it contains a description of the plan of
   distribution with respect to the resale of such Exchange Notes. Under the
   Registration Rights Agreement, the Issuer and Bermuda Holdings is required to
   allow Participating Broker-Dealers and other persons, if any, subject to
   similar prospectus delivery requirements, to use this Prospectus as it may be
   amended or supplemented from time to time, in connection with the resale of
   such Exchange Notes.

    
                              PLAN OF DISTRIBUTION

     Each Participating Broker-Dealer pursuant to the Exchange Offer must
   acknowledge that it will deliver a prospectus in connection with any resale
   of such Exchange Notes. This Prospectus, as it may be amended or supplemented
   from time to time, may be used by a Participating Broker-Dealer in connection
   with resales of Exchange Notes received in exchange for Old Notes where such
   Old Notes were acquired as a result of market-making activities or other
   trading activities. The Issuer and Bermuda Holdings have agreed that it will
   make this Prospectus, as amended or supplemented, available to any
   Participating Broker-Dealer for use in connection with any such resale and
   Participating Broker-Dealers shall be authorized to deliver this Prospectus
   for a period not exceeding 180 days after the Expiration Date. In addition,
   until April 28, 1998 (180 days after the date of this Prospectus), all
   dealers effecting transactions in the Exchange Notes may be required to
   deliver a prospectus.      

                                      44
<PAGE>
 
     Neither the Issuer nor Bermuda Holdings will receive any proceeds from any
   sales of the Exchange Notes by Participating Broker-Dealers. Exchange Notes
   received by Participating Brokers-Dealers for their own account pursuant to
   the Exchange Offer may be sold from time to time, in one or more transactions
   in the over-the-counter market, in negotiated transactions, through the
   writing of options on the Exchange Notes or a combination of such methods of
   resale, at market prices prevailing at the time of resale, at prices related
   to such prevailing market prices or at negotiated prices. Any such resale may
   be made directly to purchasers or to or through brokers or dealers who may
   receive compensation in the form of commissions or concessions from any such
   Participating Broker-Dealer that resells the Exchange Notes that were
   received by it for its own account pursuant to the Exchange Offer. Any broker
   or dealer that participates in a distribution of such Exchange Notes may be
   deemed to be an "underwriter" within the meaning of the Securities Act and
   any profit on any such resale of Exchange Notes and any omissions or
   concessions received by any such persons may be deemed to be underwriting
   compensation under the Securities Act. The Letter of Transmittal states that
   by acknowledging that it will deliver and by delivering a prospectus, a
   Participating Broker-Dealer will not be deemed to admit that it is an
   "underwriter" within the meaning of the Securities Act.

     The Issuer will promptly send additional copies of this Prospectus and any
   amendment or supplement to this Prospectus to any Participating Broker-Dealer
   that requests such documents in the Letter of Transmittal. See "The Exchange
   Offer."

                          CERTAIN TAX CONSIDERATIONS

   Certain U.K., U.S. and Bermuda Tax Considerations

     The following summary of certain U.S., U.K. and Bermuda tax consequences of
   the acquisition, ownership and disposition of the Senior Notes by a "U.S.
   Holder" (as defined below) is set forth with respect to U.S. federal income
   tax matters based upon the opinion of Debevoise & Plimpton, U.S. tax counsel
   to the Issuer, with respect to U.K. tax matters based upon the opinion of
   Clifford Chance, U.K. tax counsel to the Issuer, and with respect to Bermuda
   tax matters based upon the opinion of Conyers, Dill & Pearman, Bermuda tax
   counsel to the Issuer. Such firms express no opinion as to, and have not
   independently confirmed, any factual or accounting matters, determinations or
   conclusions described below. The summary describes certain U.S. federal
   income, U.K. and Bermuda tax consequences of the acquisition, ownership and
   disposition of the Senior Notes as of the date of this Prospectus. The
   Summary is for general information purposes only and does not purport to be a
   complete analysis of all tax considerations that may be applicable to U.S.
   Holders of Senior Notes. Except where noted, it deals only with Senior Notes
   beneficially owned as capital assets by a purchaser that is, for U.S. federal
   income tax purposes, (1) a citizen or resident of the United States, (2) a
   corporation, partnership or other entity created or organized in, or under
   the laws of, the United States or any political subdivision thereof or (3) an
   estate or trust the income of which is subject to U.S. federal taxation
   regardless of its source (a "U.S. Holder") and does not address the U.K. tax
   consequences to a holder that is resident (or, in the case of an individual,
   who is either resident or ordinarily resident or both) for U.K. tax purposes
   in the U.K., that is domiciled under U.K. law in the U.K. or that carries on
   business in the U.K. through a branch or agency. It does not deal with
   special situations, such as those of securities dealers, banks, tax-exempt
   organizations, life insurance companies, persons that hold the Senior Notes
   as part of a hedging transaction or straddle or conversion transaction or
   persons whose functional currency is not the U.S. dollar. It also does not
   deal with state or local taxes, or U.S. federal taxes other than income
   taxes.

     The statements regarding U.S. federal income tax consequences set forth
   below are based upon the provisions of the U.S. Internal Revenue Code of
   1986, as amended (the "Code"), and regulations, rulings and judicial
   decisions thereunder as of the date of this Prospectus. The statements
   regarding U.K. and Bermuda tax laws set forth below are based on those laws
   as in force on the date of this Prospectus. Such authorities may be repealed,
   revoked or modified, possibly with retroactive effect, in which case tax
   consequences different from those discussed below could result. The
   statements regarding U.S. federal income, U.K. and Bermuda tax consequences
   set forth below assume that the Senior Notes were issued, and transfers
   thereof and payments thereon have been and will continue to be made, in
   accordance with the Indenture and the Depositary Agreement.

     For purposes of the U.K. Treaty (as defined below) and the Code, U.S.
   Holders of the Book-Entry Interests will be treated as owners of the Senior
   Notes underlying such Book-Entry Interests and, except as noted below, the
   tax consequences of owning the Book-Entry Interests will be the same as those
   applicable to ownership of the Senior Notes.

     PERSONS CONSIDERING THE ACQUISITION, OWNERSHIP OR DISPOSITION OF THE SENIOR
   NOTES SHOULD CONSULT THEIR OWN TAX ADVISERS CONCERNING THE U.S. FEDERAL
   INCOME, U.K. AND BERMUDA TAX CONSEQUENCES IN LIGHT OF THEIR PARTICULAR
   SITUATIONS AS WELL AS ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE,
   LOCAL OR FOREIGN TAXING JURISDICTIONS.

   Certain Tax Consequences of the Exchange Offer

   United States. The exchange of Old Notes for Exchange Notes pursuant to the
   Exchange Offer will not result in any federal income tax consequences to
   holders. When a holder exchanges an Old Note for an Exchange Note pursuant to
   the Exchange Offer, such holder will have the same adjusted basis and holding
   period in the Exchange Note as in the Old Note immediately before the
   Exchange.

   United Kingdom. The exchange of Old Notes for Exchange Notes pursuant to the
   Exchange Offer will not result in any liability to United Kingdom taxation
   for holders of Old Notes who are neither resident nor, in the case of a
   holder who is an individual, ordinarily resident in the United Kingdom for
   the purposes of United Kingdom taxation, and further who do not carry on a
   trade, profession or vocation in the United Kingdom through a branch or
   agency in the United Kingdom to which the Old Notes or the Exchange Notes are
   attributable.

                                      46
<PAGE>
 
   Bermuda. The exchange of Old Notes for Exchange Notes pursuant to the
   Exchange Offer will not result in any Bermuda tax consequences.

   Taxation of U.S. Holders of the Senior Notes

    Bermuda

     Payments under the Guarantee.  Under Bermuda law, no withholding or
   deduction will be required to be made on account of payments made by Bermuda
   Holdings under the Guarantee.

    United Kingdom

     Payments on the Senior Notes.  The rules relating to UK withholding tax
   have been amended by legislation enacted by Finance Act 1996 supported by
   regulations laid thereunder. However, as some further regulations have still
   to be drafted, the rules set out below may be subject to amendment.

         (a) The Senior Notes will constitute "quoted Eurobonds" provided they
     continue to carry a right to interest and provided that they are and
     continue to be in bearer form and quoted on a recognized stock exchange
     (the Luxembourg Stock Exchange is a recognized stock exchange for this
     purpose).

         (b) Payments of interest on Senior Notes which are and continue to be
     quoted Eurobonds and are in global form and are held in a "recognized
     clearing system" (DTC is so recognized) may be made without withholding or
     deduction for or on account of UK income tax, provided that:

             (i) payment is made direct to the recognized clearing system; or

             (ii) payment is made to, or at the direction of, a depositary for
         the recognized clearing system and the paying agent has obtained a
         valid declaration PA 3 from the depositary; or

             (iii) the paying agent has obtained a notice from the Inland
         Revenue instructing the paying agent to pay the interest with no tax
         deducted.

         (c) If the Senior Notes are issued in definitive form and are and
     continue to be quoted Eurobonds, then payments of interest on the Senior
     Notes may be made without such withholding or deduction where:

             (i) the person by or through whom the payment is made is not in 
         the UK; or

             (ii) the payment is made by or through a person who is in the UK 
         and

         (aa) the interest is paid on a Senior Note held in a recognized
     clearing system as defined for the relevant purpose and one of the
     conditions set out in paragraph (b)(i), (ii) and (iii) above is satisfied;
     or

         (bb) a person who is not resident in the UK is beneficially entitled to
     the interest and is the beneficial owner of the Senior Note on which the
     interest is paid and either:

             (1) the paying agent obtains a valid declaration PA1 from the said
         person on the occasion of each payment; or

             (2) the paying agent obtains on the occasion of each payment a
         valid declaration PA2 from another person who holds the Senior Notes
         for the non-resident person and who is entitled to arrange for the
         interest to be paid with no UK tax deducted; or

             (iii) the paying agent has obtained a notice from the Inland
         Revenue instructing the paying agent to pay the interest with no tax
         deducted.

     In other cases, and in particular if either (A) payments on the Senior
   Notes are made at a time they are not quoted on a recognized stock exchange
   or (B) Definitive Senior Notes in registered form are issued, interest and
   Additional Amounts, if any, will be paid after deduction of U.K. income tax
   at the lower rate (currently 20%). A U.S. Holder of a Senior Note will
   normally be eligible to recover in full any U.K. tax withheld from payments
   of interest to which such U.S. Holder is beneficially entitled by making a
   claim for refund under the U.S./U.K. Treaty on the appropriate form filed in
   duplicate with

                                      47
<PAGE>
 
   the Internal Revenue Service Center Director with which such U.S. Holder's
   last U.S. federal income tax return was filed. Alternatively, a claim may be
   made by a U.S. Holder in advance of a payment of interest. If the claim is
   accepted by the U.K. Inland Revenue, they will authorize subsequent payments
   to that U.S. Holder to be made without the withholding of U.K. tax. Claims
   for refund must be made within six years of the end of the U.K. year of
   assessment (generally April 5th in each year) to which the interest related
   and must be accompanied by the original statement provided by the Company (or
   any nominee holding the Senior Notes on the U.S. Holder's behalf) when the
   interest payment was made showing the amount of income tax deducted and when
   the interest payment was made. Because a claim for refund is not considered
   until the U.K. Inland Revenue receives the appropriate form from the IRS,
   forms should be sent to the IRS well before the end of the applicable
   limitation period,

     In the case of Senior Notes which are quoted Eurobonds, a person in the UK
   who in the course of a trade or profession:

         (i) by means of coupons, warrants or bills of exchange, collects or
     secures payment of or receives interest on Senior Notes for a Noteholder;
     or

         (ii) arranges to collect or secure payment of interest on Senior Notes
     for a Noteholder; or

         (iii) acts as a custodian of such Notes and receives interest on such
     Senior Notes or directs that interest on such Senior Notes be paid to
     another person or consents to such payment will be required to withhold UK
     income tax at the lower rate (currently 20%), subject to certain
     exceptions, including the following:

             (a) the Senior Notes are held in a recognized clearing system and 
         either:

                 (i) the collecting agent pays or accounts for the interest
             directly or indirectly to the recognized clearing system and where
             such payment or account is made to, or at the direction of, a
             depositary for the recognized clearing system, the collecting agent
             holds a valid declaration CA3 from the depositary; or

                 (iii) the collecting agent is acting as depositary for the
             recognized clearing system in respect of the Senior Notes; or

             (b) the person beneficially entitled to the interest beneficially
         owns the Senior Notes and is not resident in the UK and the collecting
         agent either

                 (i) holds a valid declaration CA1 from the said person; or

                 (ii) holds a valid declaration CA2 from a person (other than
             the beneficial owner of the Notes) to whom the interest is payable
             or who is entitled to arrange for the interest to be collected
             without deduction of UK tax and who is not a collecting agent in
             the UK.

     Holders of Senior Notes who request Definitive Senior Notes in registered
   form will not be entitled to the payment of any Additional Amounts in respect
   of the U.K. tax withheld. In certain other cases in which Senior Notes are
   exchanged for Definitive Senior Notes, U.S. Holders of Definitive Senior
   Notes will be entitled to the payment of Additional Amounts in respect of the
   U.K. tax withheld. See "Description of Senior Notes--Payment of Additional
   Amounts."

     Under provisions of the U.K. Finance Act 1995, interest on the Senior Notes
   received without deduction or withholding will not be subject to U.K. tax by
   direct assessment in the hands of a holder of Senior Notes who is not
   resident for tax purposes in the U.K. unless that holder carries on a trade,
   profession or vocation within the U.K. through a U.K. branch or agency in
   connection with which the interest is received or to which the Senior Notes
   are attributable (in which case certain exemptions may be available).

     Sale or Disposition (including Redemption). A U.S. Holder (not resident or
   ordinarily resident in the U.K. and not engaging in business in the U.K.
   through a branch or agency) will not be subject to U.K. tax (including
   withholding tax) on the sale, redemption (other than redemption at a
   premium), retirement or other disposition of a Senior Note. Similarly, such a
   U.S. Holder will not be subject to U.K. tax where an interest in the Global
   Note is exchanged for a Definitive Senior Note.

     For U.K. tax purposes, a disposal of a Senior Note by an individual holder
   resident or ordinarily resident for U.K. tax purposes in the U.K. or who
   carries on a trade, profession or vocation in the U.K. through a branch or
   agency to which the Senior Note is attributable may give rise to a chargeable
   gain or allowable loss for the purposes of taxation of capital gains. It
   should be noted that, to calculate any gain on a disposal of Senior Notes,
   sterling values are compared at acquisition and

                                      48
<PAGE>
 
   disposal. Accordingly, a taxable gain can arise on maturity, for example,
   even where the amount of foreign currency received is less than, or the same
   as, the amount paid for the Senior Notes. A transfer of a Senior Note by an
   individual holder resident or ordinarily resident for U.K. tax purposes in
   the U.K. or who carries on a trade in the U.K. through a branch or agency to
   which the Senior Note is attributable may give rise to a charge to tax on
   income in respect of an amount representing interest on the Senior Note which
   has accrued since the preceding interest payment date.

     In relation to a holder which is a company that is subject to U.K.
   corporation tax (other than a company established for charitable purposes
   only, authorized unit trusts and approved investment trusts and certain other
   categories of company which are not taxable on chargeable gains), the Senior
   Notes will be treated on disposal as "qualifying corporate bonds" with the
   result that on a disposal of the Senior Notes by such a company, neither
   chargeable gains nor allowable losses will arise for the purposes of taxation
   of chargeable gains. Holders of Senior Notes who are within the charge to
   United Kingdom corporation tax will be charged to tax generally on all
   profits and gains (including interest and other accruals or, as the case may
   be, movements in value, gains made on disposals and profits attributable to
   exchange rate fluctuations) arising from the Senior Notes broadly in
   accordance with their statutory accounting treatment. Such profits and gains
   will be charged to tax as income in respect of each accounting period to
   which they are allocated for accounting purposes. Relief may be available for
   related expenses and losses on a similar basis.

     U.K. Stamp Duty and Stamp Duty Reserve Tax.   No U.K. Stamp Duty or Stamp
   Duty Reserve Tax is payable on the issue of the Global Note or on the issue
   or, once the Senior Notes are listed on the Luxembourg Stock Exchange, the
   transfer by delivery of a Senior Note or on its redemption except that stamp
   duty reserve tax (currently at the rate of 0.5%) could be payable on an
   agreement to transfer any Senior Note issued after 25 November 1996 unless,
   inter alia, the Senior Note is listed on a recognized stock exchange, does
   not carry a right of conversion into securities not so listed and the
   agreement to transfer the Senior Note is not made in contemplation of, or as
   part of an arrangement for, a takeover of the Company.

     Although the Issuer intends to list the Exchange Notes on the Luxembourg
   Stock Exchange, it is not expected that the Exchange Notes will be listed on
   the date of issue. During the period prior to such listing of the Exchange
   Notes and the Old Notes, any agreement to transfer the Global Note or Senior
   Note or any interest therein may be subject to Stamp Duty Reserve Tax if made
   before such Senior Notes are so listed, unless it can be shown that (i) the
   amount of interest and Additional Amounts payable on the Senior Notes neither
   exceeds a reasonable commercial return on the nominal amount of the capital
   nor falls to be determined to any extent by reference to the results of, or
   any part of, a business or to the value of any property; (ii) the Senior
   Notes carry a right on repayment to an amount which does not exceed the
   nominal value of the capital (or if it does, such amount is reasonably
   comparable with what is generally repayable (in respect of a similar nominal
   amount of capital) under the terms of issue of loan capital listed in the
   Official List of The London Stock Exchange); and (iii) the Senior Notes do
   not carry a right (exercisable then or later) of conversion into shares or
   other securities, or to the acquisition of shares or other securities,
   including loan capital of the same description.

     U.K. Inheritance Tax. Senior Notes represented by the Global Note that are
   not treated as situated in the U.K. and are beneficially owned by an
   individual domiciled outside the U.K. will not be subject to U.K. inheritance
   tax. If a Senior Note is subject to U.K. inheritance tax and U.S. federal
   estate tax, the U.S./U.K. convention for the avoidance of double taxation
   with respect to estate and gift taxes may entitle a U.S. Holder to credit or
   relief in respect of the U.K. tax.


    United States

     Payments on the Senior Notes. For U.S. federal income tax purposes, a U.S.
   Holder will include interest and Additional Amounts, if any, payable on the
   Senior Notes in income when received or accrued in accordance with the U.S.
   Holder's method of accounting. Such interest will constitute "foreign source
   income" for foreign tax credit purposes.

     Subject to certain limitations, a U.S. Holder would generally be required
   to include the full amount of the interest payment (without reduction for the
   U.K. withholding tax, if any) and Additional Amounts, if any, and would be
   entitled to a credit against its U.S. federal income tax liability, or a
   deduction in computing its U.S. federal taxable income, for U.K. taxes
   withheld from payments of interest to which such U.S. Holder is beneficially
   entitled. In the case of a U.S. Holder entitled to claim a refund of any U.K.
   tax withheld, no U.S. foreign tax credit or deduction may be claimed for the
   amount of U.K. tax eligible for a refund, whether or not such refund is
   sought, to the extent that it is reasonably certain that such U.K. tax will
   be refunded. If a U.S. Holder receives a refund of U.K. tax for which a
   deduction or foreign tax credit was previously claimed, the U.S. Holder
   generally must (i) in the case of a deduction, include the refund in gross
   income or (ii), in the case of a foreign tax credit, notify the Service of
   the receipt of the refund, according to the requirements of Section

                                      49
<PAGE>
 
1.905-4T of the Treasury Regulations or any successor provisions, and the
Service will redetermine the U.S. Holder's U.S. federal income tax liability for
the taxable year in which the credit was originally claimed.

     Sale or Disposition (including Redemption).  For U.S. federal income tax
purposes, taxable gain or loss generally will be recognized by a U.S. Holder on
the sale, redemption, retirement or other disposition of the Senior Notes
measured by the difference between (1) the sum of (a) any cash and (b) the fair
market value of any property received (except in the case of a cash basis
taxpayer, to the extent the cash or property received is attributable to accrued
interest, which will be taxable as such) and (2) the U.S. Holder's tax basis in
the Senior Notes. Subject to the market discount rules discussed below, any gain
or loss recognized generally will be capital gain or loss. Any such gain
generally will constitute "U.S. source income" for foreign tax credit purposes.

     Market Discount.  A U.S. Holder (other than a U.S. Holder that makes the
election described below) that purchases a Senior Note at a market discount that
is not de minimis generally will be required to treat any gain realized upon the
disposition of such Senior Note as interest income to the extent of the market
discount accruing during the period such holder held such Senior Note. A U.S.
Holder may also be required to recognize as ordinary income any principal
payments with respect to a Senior Note to the extent such payments do not exceed
the accrued market discount on the Senior Note. For this purpose, market
discount generally equals the excess of the stated redemption price of the
Senior Note over the basis of the Senior Note in the hands of the holder
immediately after its acquisition. However, market discount is deemed not to
exist if the market discount is less than a statutorily defined de minimis
amount equal to 1/4 of 1 percent of the Senior Note's stated redemption price
multiplied by the number of complete years to the Senior Note's maturity after
the holder acquired the Senior Note.

     The market discount rules also provide that a U.S. Holder of Senior Notes
that were acquired at a market discount may be required to defer the deduction,
until the Senior Notes are disposed of, of a portion of the interest on any
indebtedness incurred or maintained to acquire or carry the Senior Notes.

     A U.S. Holder of a Senior Note acquired at a market discount may elect to
include market discount in income as the discount accrues. In such a case, the
foregoing rules with respect to the recognition of ordinary income on
dispositions and with respect to the deferral of interest deductions on
indebtedness related to such Senior Note would not apply. The current inclusion
election applies to all market discount obligations acquired on or after the
first day of the first taxable year to which the election applies, and may not
be revoked without the consent of the Service.

     Amortizable Bond Premium.  Generally, if the tax basis of an obligation
held as a capital asset exceeds the amount payable at maturity of the
obligation, such excess may constitute amortizable bond premium that the holder
of such obligation may elect to amortize under the constant interest rate method
and deduct over the period from the holder's acquisition date to the
obligation's maturity date. The amortizable bond premium deduction is treated as
a reduction of interest on the bond instead of as a deduction, except as
Treasury Regulations may otherwise provide. A holder that elects to amortize
bond premium must reduce its tax basis in the related obligation by the amount
of the aggregate deductions allowable for the amortizable bond premium. Any
election to amortize bond premium will apply to all bonds (other than bonds the
interest on which is excludible from gross income) held by the holder at the
beginning of the first taxable year to which the election applies or thereafter
acquired by the holder. The election may not be revoked without the consent of
the Service.

     In the case of an obligation, such as a Senior Note, that may be called at
a premium prior to maturity, an earlier call date is treated as its maturity
date, and the amount of bond premium is determined by treating the amount
payable on such call date as the amount payable at maturity if such a
calculation produces a smaller amortizable bond premium for the period ending on
such call date. If a U.S. Holder of a Senior Note is required to amortize and
deduct bond premium by reference to a call date, the Senior Note will be treated
for this purpose as maturing on such date for the amount payable, and, if not
redeemed on such date, as reissued on such date for the amount so payable. If a
Senior Note purchased at a premium is redeemed pursuant to a call prior to such
early call date or its maturity, a U.S. Holder that has elected to deduct bond
premium may deduct the excess of its adjusted basis in the Senior Note over the
amount received on redemption (or, if greater, the amount payable on maturity)
as an ordinary loss in the taxable year of redemption.

     United States Information Reporting and Backup Withholding.  In general,
U.S. information reporting requirements will apply to payments of principal,
premium and interest on a Senior Note and on the proceeds of the sale of a
Senior Note before maturity to a non-corporate U.S. Holder, and U.S. "backup
withholding" at a rate of 31% will apply to such payments if the U.S. Holder
fails to provide an accurate taxpayer identification number or to report all
interest and dividends required to be shown on its federal income tax returns.


                                      50
<PAGE>
 
     The amount of any backup withholding from a payment to a U.S. Holder will
be allowed as a credit against such U.S. Holder's U.S. federal income tax
liability and may entitle such U.S. Holder to a refund, provided that the
required information is furnished to the Service.


                             ERISA CONSIDERATIONS

     The Company, the obligor with respect to the Senior Notes, and its
affiliates may be considered a "party in interest" (within the meaning of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA")) or a
"disqualified person" (within the meaning of Section 4975 of the Code) with
respect to many employee benefit plans ("Plans") that are subject to ERISA. Any
purchaser proposing to acquire Senior Notes with assets of any Plan should
consult with its counsel. The purchase and/or holding of Senior Notes by a Plan
that is subject to the fiduciary responsibility provisions of ERISA or the
prohibited transaction provisions of Section 4975 of the Code (including
individual retirement arrangements and other plans described in Section
4975(e)(1) of the Code) and with respect to which the Issuer, Bermuda Holdings
or any affiliate is a service provider (or otherwise is a party in interest or a
disqualified person) may constitute or result in a prohibited transaction under
ERISA or Section 4975 of the Code, unless such Senior Notes are acquired
pursuant to and in accordance with an applicable exemption, such as Prohibited
Transaction Class Exemption ("PTCE") 84-14 (an exemption for certain
transactions determined by an independent qualified professional asset manager),
PTCE 91-38 (an exemption for certain transactions involving bank collective
investment funds), PTCE 90-1 (an exemption for certain transactions involving
insurance company pooled separate accounts), PTCE 95-60 (an exemption for
transactions involving certain insurance company general accounts) or PTCE 96-23
(an exemption for certain transactions determined by an in-house professional
asset manager).

                    INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

THE ISSUER

      The Issuer is a public limited company organized under the laws of England
and Wales.  Sections 310 and 727 of the Companies Act of 1985, as amended (the
"Companies Act"), and Article 17 of the Issuer's  Articles of Association
provide for the indemnification or exemption from liability, under the
circumstances set forth below, of officers and auditors of the Issuer against
certain liabilities in respect of negligence, default, breach of duty or breach
of trust in relation to the Issuer, and for the purchase and maintenance of
insurance by the Issuer on behalf of officers, directors, and auditors of the
Issuer against certain liabilities asserted against, and incurred by, any such
officer, director, or auditor in such capacity.  Set forth below is the text of
Sections 310 and 727 of the Companies Act and the text of Article 17 of the
Issuer's Articles of Association.

      Section 310 of the Companies Act of 1985, as amended, provides as follows:

      "SEC. 310.  Provisions exempting officers and auditors from liability.
 
      310(1)  This section applies to any provision, whether contained in a
      company's articles or in any contract with the company or otherwise, for
      exempting any officer of the company or any person (whether an officer or
      not) employed by the company as auditor from, or indemnifying him against,
      any liability which by virtue of any rule of law would otherwise attach to
      him in respect of any negligence, default, breach of duty or breach of
      trust of which he may be guilty in relation to the company.

      310(2)  Except as provided by the following subsection, any such provision
              is void.

      310(3)  This section does not prevent a company --

            (a) from purchasing and maintaining for any such officer or auditor
                insurance against any such liability, or

            (b) from indemnifying any such officer or auditor against any
                liability incurred by him --
 
               (i)  in defending any proceedings, (whether civil or criminal) in
                    which judgment is given in his favour or he is acquitted, or

                                      II-1
<PAGE>
 
               (ii) in connection with any application under section 144(3) or
                    (4) (acquisition of shares by innocent nominee) or section
                    727 (general power to grant relief in case of honest and
                    reasonable conduct) in which relief is granted to him by the
                    court."

Section 727 of the Companies Act 1985 provides:

   "(1) If in any proceedings for negligence, default, breach of duty or breach
of trust against an officer of a company or a person employed by a company as
auditor (whether he is or is not an officer of the company) it appears to the
court hearing the case that that officer or person is or may be liable in
respect of the negligence, default, breach of duty or breach of trust, but that
he has acted honestly and reasonably, and that having regard to all the
circumstances of the case (including those connected with his appointment) he
ought fairly to be excused for the negligence, default, breach of duty or breach
of trust, that court may relieve him, either wholly or partly, from his
liability on such terms as it thinks fit.

   (2) If any such officer or person as abovementioned has reason to apprehend
that any claim will or might be made against him in respect of any negligence,
default, breach of duty or breach of trust, he may apply to the court for
relief; and the court on the application has the same power to relieve him as
under this section it would have had if it had been a court before which
proceedings against that person for negligence, default, breach of duty or
breach of trust had been brought.

   (3) Where a case to which subsection (1) applies is being tried by a judge
with a jury, the judge, after hearing the evidence, may, if he is satisfied that
the defendant or defender ought in pursuance of that subsection to be relieved
either in whole or in part from the liability sought to be enforced against him,
withdraw the case in whole or in part from the jury and forthwith direct
judgment to be entered for the defendant or defender on such terms as to costs
or otherwise as the judge may think proper."

     Article 17 of the Issuer's Articles of Association provides as follows:

     "17.(1)subject to the provisions of and to the extent permitted by the
            Statutes, every director, other officer or auditor of the Company
            shall be indemnified out of the assets of the Company against any
            liability incurred by him in the actual or purported execution or
            discharge of his duties or the exercise or purported exercise of his
            powers or otherwise in relation to or in connection with his duties,
            powers or office, but:

            (a) this indemnity shall not apply to any liability to the extent
                that it is recovered from any other person; and

                                      II-2
<PAGE>
 
            (b) the indemnity is subject to such officer or auditor taking all
                reasonable steps to effect such recovery, so that the indemnity
                shall not apply to the extent that an alternative right of
                recovery is capable of being enforced.

      17.(2)  Regulation 188 of Table A shall not apply."

   As of June 30, 1997, Bermuda Holdings had purchased primary directors and
officers liability insurance from New Hampshire Insurance Company (Europe) in
the amount of (Pounds)12.5 million, with excess cover of (Pounds)7.5 million
provided by Executive Risk Insurance Company and further excess cover of
(Pounds)5 million provided by ACE Insurance Company, covering directors and

      Bermuda Holdings is a company organized under the Laws of Bermuda.
Sections 98 and 98A of the Companies Act of 1981 of Bermuda and Article 28 of
the Bye-Laws of Bermuda Holdings provide for the indemnification, except under
circumstances set forth below, of directors, officers or auditors of Bermuda
Holdings from losses or liabilities occurring in connection with their execution
of their duties or supposed duties in such  capacities, and for the purchase and
maintenance of insurance by Bermuda Holdings on behalf  of its directors and
officers against any liabilities asserted against such directors or officers by
virtue of a violation of their duties in such capacities.  Set forth below is
the text of Sections 98 and 98A of the Companies Act of 1981 of Bermuda and the
text of Article 28 of the Bye-Laws of Bermuda Holdings.

      Section 98 of the Companies Act of 1981 of Bermuda provides:

      "(1)  Subject to subsection (2), a company may in its bye-laws or in any
      contract or arrangement between the company and any officer, or any person
      employed by the company as auditor, exempt such officer or person from, or
      indemnify him in respect of, any loss arising or liability attaching to
      him by virtue of any rule of law in respect of any negligence, default,
      breach of duty or breach of trust of which the officer or person may be
      guilty in relation to the company or any subsidiary thereof.

      (2)  Any provision, whether contained in the bye-laws of a company or in
      any contract or arrangement between the company and any officer, or any
      person employed by the company as auditor, exempting such officer or
      person from, or indemnifying him against any liability which by virtue of
      any rule of law would otherwise attach to him in respect of any fraud or
      dishonesty of which he may be guilty in relation to the company shall be
      void.  Provided that --

                                      II-3
<PAGE>
 
         (a)  nothing in this section shall operate to deprive any person of any
         exemption or right to be indemnified in respect of anything done or
         omitted to be done by him while any such provision was in force; and

         (b)  notwithstanding anything in this section, a company may, in
         pursuance of any such provision as aforesaid indemnify any such officer
         or auditor against any liability incurred by him in defending any
         proceedings, whether civil or criminal in which judgment is given in
         his favor or in which he is acquitted or when relief is granted to him
         by the Court under section 281."

      Section 98A of the Companies Act 1981 of Bermuda provides as follows:

      "98A  A company may purchase and maintain insurance for the benefit of any
      officer of the company against any liability incurred by him under
      paragraph (b) of subsection (1) of Section 97 in his capacity as an
      officer of the Company or indemnifying such an officer in respect of any
      loss arising or liability attaching to him by virtue of any rule of law in
      respect of any negligence, default, breach of duty or breach of trust of
      which the officer may be guilty in relation to the company or any
      subsidiary thereof and nothing in this Act shall make void or voidable any
      such policy."

(Section 97(1)(b), referenced in Section 98A, provides that every officer of a
company in exercising his powers and discharging his duties shall "exercise the
care, diligence and skill that a reasonably prudent person would exercise in
comparable circumstances.")

      Article 28 of the Bye-Laws of Bermuda Holdings provides as follows:

      "(a)  The Directors, Secretary and other Officers for the time being of
      the Company and the liquidator or trustees (if any) for the time being
      acting in relation to any of the affairs of the Company and every one of
      them, and their heirs, executors and administrators, shall be indemnified
      and secured harmless out of the assets of the Company from and against all
      actions, costs, charges, losses, damages and expenses which they or any of
      them, their heirs, executors or administrators, shall or may incur or
      sustain by or by reason of any act done, concurred in or omitted in or
      about the execution of their duty, or supposed duty, or in their
      respective offices or trusts, and none of them shall be answerable for the
      acts, receipts, neglects or defaults of the others of them or for joining
      in any receipts for the sake of conformity, or for the acts of or the
      solvency or honesty of any bankers or other persons with whom any moneys
      or effects belonging to the Company shall or may be lodged or deposited
      for safe custody, or for insufficiency or deficiency of any security upon
      which any moneys of or belonging to the Company shall be placed out on or
      invested, or for any other loss, misfortune or damage which may happen in
      the execution of their respective offices or trusts, or in relation
      thereto, PROVIDED THAT this indemnity shall not extend to any matter in
      respect of any wilful negligence, wilful default, fraud or dishonesty
      which may attach to any of said persons.

                                      II-4
<PAGE>
 
      (b)  Every Director and Officer of the Company shall be indemnified out of
      the funds of the Company against all liabilities incurred by him as such
      Director or Officer of the Company in defending any proceedings, whether
      civil or criminal, in which judgment is given in his favor, or in which he
      is acquitted, or in connection with any application under the Companies
      Acts in which relief from liability is granted to him by the court.  Such
      funds shall be advanced to such Director or Officer on his incurring
      liability prior to judgment provided that should he be found guilty of a
      criminal or other offense for which he cannot by law be indemnified he
      shall reimburse the Company the funds advanced."

      As of June 30, 1997, Bermuda Holdings had purchased primary directors and
officers liability insurance from New Hampshire Insurance Company (Europe) in
the amount of (Pounds)12.5 million, with excess cover of (Pounds)7.5 million

ITEM 17.  UNDERTAKINGS

     (A)  RULE 415 OFFERING.

     The undersigned Registrants hereby undertake:

     (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

        (i)  To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;

        (ii)  To reflect in the prospectus any facts or events arising after the
     effective date of the Registration Statement (or the most recent post-
     effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     Registration Statement;

        (iii)  To include any material information with respect to the plan of
     distribution it previously disclosed in the Registration Statement or any
     material change to such information in the Registration Statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained  in periodic reports filed by Bermuda Holdings pursuant
to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the Registration Statement.

     (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

       

                                      II-7
<PAGE>
   
 
     (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (B)  FILINGS INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS BY REFERENCE.

     The undersigned Registrants hereby undertake that, for purpose of 
determining any liability under the Securities Act of 1933, each filing of 
Bermuda Holdings annual report pursuant to Section 13(a) or 15(d) of the 
Securities Exchange Act of 1934 that is incorporated by reference in the 
registration statement shall be deemed to be a new registration statement 
relating to the securities offered therein, and the offering of such securities 
at that time shall be deemed to be the initial bona fide offering thereof.

     (C)  REQUEST FOR ACCELERATION OF EFFECTIVE DATE.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the 
registrants pursuant to the foregoing provisions, or otherwise, the registrants 
have been advised that in the opinion of the Securities and Exchange Commission 
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for 
indemnification against such liabilities (other than the payment by the 
registrant of expenses incurred or paid by a director, officer or controlling 
person of the registrant in the successful defense of any action, suit or 
proceeding) is asserted by such director, officer or controlling person in 
connection with the securities being registered, the registrants will, unless in
the opinion of their counsel the matter has been settled by controlling 
precedent, submit to a court of appropriate jurisdiction the question whether 
such indemnification by them is against public policy as expressed in the 
Securities Act of 1933 and will be governed by the final adjudication of such 
issue.

     (D)  UNDERTAKINGS ON BEHALF OF THE DEPOSITARY     

          (i) The Depositary hereby undertakes to make available at the
           -
principal office of the Depositary in the United States, for inspection by
holders of the Receipt, any reports and communications received from the issuer
of the deposited security which are both (1) received by the Depositary as the
holder of the deposited security, and (2) made generally available to the
holders of the underlying security by the Issuer.

         (ii) If the amounts of fees charged are not disclosed in the
          --
prospectus, the Depositary undertakes to prepare a separate document stating the
amount of any fee charged and describing the service for which it is charged and
to deliver promptly a copy of such fee schedule without charge to anyone upon
request. The Depositary undertakes to notify each registered holder of a Receipt
thirty days before any change in the fee schedule.
