                                EXPLANATORY NOTE

        This Post-Effective Amendment to the Registration Statement contains a
  Prospectus relating to certain market-making transactions in the $100,000,000
  10 3/4% Senior Notes due 2005 of Terra Nova Insurance (U.K.) Holdings plc,
  fully and unconditionally guaranteed by Terra Nova (Bermuda) Holdings Ltd. In
  order to register under Rule 415 of the Securities Act of 1933 those Senior
  Notes that will be offered and sold in market-making transactions, the
  appropriate box on the cover page of the Registration Statement has been
  checked and the undertakings required by Item 512(a) of Regulation S-K have
  been included in Item 17 of Part II.

                                 $100,000,000

                     Terra Nova Insurance (UK) Holdings plc

                         10 3/4% Senior Notes due 2005
           fully and unconditionally guaranteed on a senior basis by

                       Terra Nova (Bermuda) Holdings Ltd.

   The 10 3/4% Senior Notes due 2005 offered hereby (the "Senior Notes") were
originally issued under a Prospectus dated June 27, 1995 by Terra Nova Insurance
(UK) Holdings plc (the "Issuer" or "UK Holdings") and are fully and
unconditionally guaranteed on a senior basis by Terra Nova (Bermuda) Holdings
Ltd. ("Bermuda Holdings" or the "Company").  See "Description of Senior Notes --
General" and "-- Guarantee."  The Senior Notes will mature on July 1, 2005.
Interest on the Senior Notes accrued at the rate of 10 3/4% per annum and is
payable semi-annually on each January 1 and July 1, commencing January 1, 1996.
The Senior Notes are redeemable at the option of the Issuer, in whole or in
part, at any time on or after July 1, 2000, at the redemption prices set forth
herein, plus accrued and unpaid interest to the date of redemption.  In
addition, at any time prior to July 1, 1998, in the event that the Issuer or
Bermuda Holdings consummates one or more offerings of its equity securities, all
or a portion of the proceeds of such offerings may be used to redeem up to 35%
of the Senior Notes at 109.75% of the principal amount thereof, plus accrued and
unpaid interest to the date of redemption.  The Senior Notes also may be
redeemed under the circumstances described under "Description of Senior Notes --
Tax Redemption" at 100% of the principal amount thereof, plus accrued and unpaid
interest to the date of redemption.  Upon the occurrence of a Change of Control
(as defined herein), the Issuer or Bermuda Holdings will be required to make an
offer to each holder of Senior Notes to purchase all or any part of such
holder's Senior Notes at a purchase price equal to 101% of the aggregate
principal amount thereof, plus accrued and unpaid interest to the date of
purchase.  See "Description of Senior Notes -- Purchase at the Option of Holders
upon a Change of Control" and "-- Certain Definitions."  Neither the Issuer nor
Bermuda Holdings expects to have sufficient funds available to purchase all of
the outstanding Senior Notes were they to be tendered in response to an offer
made as a result of a Change of Control.  See "Risk Factors -- Change of
Control."  The Senior Notes are not subject to any mandatory sinking fund
payment.

  The Senior Notes and the guarantee (the "Guarantee") of the Senior Notes by
Bermuda Holdings constitute unsecured senior obligations of the Issuer and
Bermuda Holdings, respectively.  The Senior Notes and the Guarantee rank pari
passu in right of payment with all other senior indebtedness of the Issuer and
Bermuda Holdings, respectively.  See "Description of Senior Notes -- General"
and "-- Guarantee."  The Senior Notes and the Guarantee constitute substantially
all of the outstanding indebtedness of the Issuer and Bermuda Holdings,
respectively.  As of the date hereof, there is no outstanding indebtedness of
either the Issuer or Bermuda Holdings which is subordinate to the Senior Notes.
Because the Issuer and Bermuda Holdings are holding companies, in order for them
to make interest and principal payments on the Senior Notes, they will be
dependent on the payment of dividends by their respective insurance company
subsidiaries, and the Senior Notes and the Guarantee will be effectively
subordinated to all existing and future liabilities of such insurance company
subsidiaries, which at December 31, 1996 consisted principally of insurance
liabilities and aggregated $1.5 billion.

   There is currently no active public market for the Senior Notes.  The Company
has been advised by Donaldson, Lufkin and Jenrette Securities Corporation
("DLJSC") that it intends to make a market for the Senior Notes; however, DLJSC
is not obligated to do so.  Any market making may be discontinued at any time
and there is no assurance that an active public market for the Senior Notes will
develop or that, if such a market develops, it will continue.  This Prospectus
has been prepared for use by DLJSC in connection with offers and sales of an
indeterminate amount of Senior Notes which may be made by it from time to time
in market-making transactions at negotiated prices relating to prevailing market
prices at the time of sale.  DLJSC may act as principal or agent in such
transactions.  See "Plan of Distribution."  DLJSC will deliver a Prospectus in
connection with the sale of the Senior Notes in market-making transactions so
long as such prospectus delivery is required under applicable law.

          OF CERTAIN FACTORS THAT SHOULD BE CONSIDERED BY PROSPECTIVE
                                   INVESTORS.

 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
      EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
          SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
              COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF

                        CONTRARY IS A CRIMINAL OFFENSE.

                             AVAILABLE INFORMATION
<PAGE>
 
     The Issuer and Bermuda Holdings have filed with the Securities and Exchange
  Commission (the "Commission") a combined registration statement (collectively,
  the "Registration Statement," which term shall include any amendment thereto)
  on Forms F-1 and S-1, and a post-effective amendment on Form S-3,
  respectively, under the Securities Act of 1933, as amended (the "Securities
  Act"), for the registration of the Senior Notes and the Guarantee offered
  hereby.  This Prospectus, which constitutes a part of the Registration
  Statement, does not contain all of the information set forth in the
  Registration Statement, certain items of which are omitted as permitted by the
  rules and regulations of the Commission.  For further information with respect
  to the Issuer, Bermuda Holdings, the Senior Notes and the Guarantee, reference
  is hereby made to the Registration Statement, including the exhibits and
  schedules thereto.  Statements made in this Prospectus concerning the contents
  of any contract, agreement or other document referred to herein are not
  necessarily complete.  With respect to each such contract, agreement or other
  document filed with the Commission as an exhibit to the Registration
  Statement, reference is hereby made to the exhibit for a more complete
  description of the matter involved, and each such statement shall be deemed
  qualified in its entirety by such reference.

     Bermuda Holdings is subject to the periodic reporting and other information
  requirements of the Securities Exchange Act of 1934, as amended (the "Exchange
  Act").  The Issuer is exempt from such requirements, but summary financial
  information of the Issuer will be provided in the reports  filed by Bermuda
  Holdings, as permitted by the rules and regulations of the Commission.  Under
  current law, for as along as the Senior Notes or Bermuda Holdings' Class A
  Ordinary Shares, par value $5.80 per share, are listed on the New York Stock
  Exchange, Inc. (the "NYSE"), Bermuda Holdings will be required to file with
  the Commission annual, quarterly and current financial information on Forms
  10-K, 10-Q and 8-K.  However, whether or not required by the Exchange Act or
  the rules and regulations of the Commission thereunder, so long as any Senior
  Notes are outstanding, Bermuda Holdings has agreed to 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 or the rules and regulations of the Commission
  thereunder, 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.

     The Registration Statement (with exhibits), as well as the reports and
  other information filed by Bermuda Holdings pursuant to the Exchange Act, may
  be inspected and copied at the public reference facilities maintained by the
  Commission at Judiciary Plaza, 450 Fifth Street, N.W., Room 1024, Washington,

     Any documents filed by the Company pursuant to Sections 13(a), 13(c), 14 or
  15(d) of the Exchange Act after the date of this Prospectus and prior to the
  termination of the offering of the Senior Notes and the Guarantee offered
  hereby shall be deemed to be incorporated by reference in this Prospectus and
  to be a part hereof.

     Any statement contained in a document incorporated or deemed to be
  incorporated by reference herein, or contained in this Prospectus, shall be
  deemed to be modified or superseded for purposes of this Prospectus to the
  extent that a statement contained herein or in any other subsequently filed
  document which also is or is deemed to be incorporated by reference herein
  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 this Prospectus.

     The Company will provide without charge to each person to whom this
  Prospectus is delivered, upon the written or oral request of such person, a
  copy of any or all of the foregoing documents incorporated herein by reference
  (other than exhibits to such documents unless such exhibits are specifically
  incorporated by reference into the foregoing documents).  Any such request
  should be directed to Jean M. Waggett, Esq., Terra Nova (Bermuda) Holdings
  Ltd., Richmond House, 2nd Floor, 12 Par-La-Ville Road, Hamilton HM 08, Bermuda
  (telephone 441-292-7731)).

                      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, five of the twelve
  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.

     The Company 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.  The Company 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

                                       3
<PAGE>
 
  natural justice of Bermuda, and was not based on an error in Bermuda law.  A
  Bermuda court may impose civil liability on the Company or its directors or
  officers in a suit brought in the Supreme Court of Bermuda against the Company
  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 U.S. 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 statements in U.S. dollars, which is its functional currency.



     SENIOR NOTES MAY NOT BE OFFERED OR SOLD TO PERSONS IN THE UNITED KINGDOM
  EXCEPT TO PERSONS WHOSE ORDINARY ACTIVITIES INVOLVE THEM IN ACQUIRING,
  HOLDING, MANAGING OR DISPOSING OF INVESTMENTS (AS PRINCIPAL OR AGENT) FOR THE
  PURPOSES OF THEIR BUSINESSES, OR OTHERWISE IN CIRCUMSTANCES WHICH DO NOT
  CONSTITUTE AN OFFER TO THE PUBLIC IN THE UNITED KINGDOM THE MEANING OF THE
  PUBLIC OFFERS OF SECURITIES REGULATIONS 1995.  ALL APPLICABLE PROVISIONS OF
  THE FINANCIAL SERVICES ACT 1986 OF THE UNITED KINGDOM MUST BE COMPLIED WITH IN
  RELATION TO ANYTHING DONE IN RELATION TO THE SENIOR NOTES IN, FROM OR
  OTHERWISE INVOLVING THE UNITED KINGDOM.

  PERSON IN THE UNITED KINGDOM IN CONNECTION WITH THE ISSUE OF THE SENIOR NOTES

  PASSED ON.

                       RATIO OF EARNINGS TO FIXED CHARGES

     The following table sets forth the Company's ratios of earnings to fixed
  charges for the years and periods indicated:

Ratio of earnings to 
  fixed charges.....................  NM    NM    NM    6.72  7.64

</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 insurance 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 service payments on the Senior Notes have
  been made.  Terra Nova had no indebtedness through December 21, 1994, the date
  of its acquisition by the Company.

                                USE OF PROCEEDS

     The Company will not receive any proceeds from the sale of the Senior Notes
  in any market-making transactions in connection with which this Prospectus may
  be delivered.

                                  RISK FACTORS

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

  HOLDING COMPANY STRUCTURE; DIVIDEND RESTRICTIONS

     The Issuer is a holding company whose primary assets are the capital stock
  of Terra Nova, and Bermuda Holdings is a holding company whose primary assets
  are the capital stock of the Issuer and Terra Nova (Bermuda).  Accordingly,
  substantially all 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

                                       5
<PAGE>
 
  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 Senior
  Notes and the Guarantee are effectively subordinated to all existing and
  future liabilities of their respective insurance company subsidiaries which at
  December 31, 1996 consisted principally of insurance liabilities and
  aggregated $1.5 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) or
  a Change of Control, the Company anticipates that it may have to borrow
  additional funds or sell some of its assets.  See "Description of Senior 
  Notes-- Purchase at the Option of Holders upon a Change of Control." 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.

                                       6
<PAGE>
 
  LEVERAGE

     As of December 31, 1996 the Company had outstanding indebtedness of
  approximately $100 million and shareholders' equity of approximately $398.7
  million.

     The Indenture permits the Company to incur additional indebtedness, subject
  to certain limitations. 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
  Companies cash requirements, the Company may seek to obtain funds form
  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  Indenture).  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 Indenture.

    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 its 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 results of the catastrophe losses suffered over the past several years
  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, that premium rates
  can be expected to decline in 1997 in the absence of a major catastrophe
  event, 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 deductible play
  an important role in reducing the number of very small claims.  In the past,
  this business was characterized by large

                                       7
<PAGE>
 
  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.  The Company carries A-, A- and A claims paying
  ability rating 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 actuarilly determined and relfect (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 invovled.  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

                                       8
<PAGE>
 
  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.


  LLOYD'S AND LONDON MARKET COMPANIES

     [An unprecedented series of natural and man-made disasters, substantial
  increases in asbestos-related and environmental pollution claims (many arising
  under policies written in the 1940s, 1950s and 1960s), and losses incurred as
  a result of the LMX Spiral (claims arising under certain reinsurance arbitrage
  programs that were common among Lloyd's syndicates and London Market companies
  during the 1980s and early 1990s and that involved writing excess of loss
  coverage for other London Market excess of loss participants), when combined
  with the cyclical downturn experienced by the property and casualty insurance
  industry in general, adversely affected certain Lloyd's syndicates and London
  Market companies in the late 1980s and early 1990s.  Lloyd's syndicates
  reported losses of (Pounds)2.1 billion in the 1989 year of account,
  (Pounds)2.3 billion in the 1990 year of account, (Pounds)2.1 billion in the
  1991 year of account and (Pounds)l.2 billion in the 1992 year of account.
  With respect to the London Market companies, management believes that, of the
  companies that participated in the London Market in 1988, more than 30 have
  since substantially ceased underwriting new business, although several new
  companies have entered the market in recent years.  With respect to Lloyd's
  syndicates, management believes that only 164 syndicates are operating for the
  1997 year of account, down from 401 in 1990.

     In response to these events, beginning in April 1993, Lloyd's adopted
  measures designed to reorganize Lloyd's and its business practices in
  substantial and fundamental ways (the "Business Plan").  As part of the
  Business Plan, Lloyd's permitted in 1994 for the first time underwriting
  capacity from limited liability corporate members.  In 1996, over 30%, or
  (Pounds)3.0 billion, of Lloyd's aggregate premium income capacity of
  (Pounds)10.0 billion has been provided by corporate members.  In May 1995,
  Lloyd's proposed a plan (the "Plan of Reconstruction") intended to address a
  number of problems, including (a) the continuing losses in 1992 and earlier
  years of account from the previously described disasters, asbestos-related and
  environmental pollution claims and LMX Spiral, (b) the inability or
  unwillingness of certain individual members of Lloyd's ("Names") to meet their
  obligations, (c) the strain on Lloyds' Central Fund and (d) litigation by
  certain Names against their agents and managing agents and, in a number of
  cases, Lloyd's itself.  During 1996, the Plan of Reconstruction was adopted,
  resulting in (i) the establishment of  a separate reinsurance company
  ("Equitas") into which all outstanding liabilities for all risks written in
  1992 or prior years of account were reinsured, with effect from September 4,
  1996, (ii) the offer to Names of a settlement totalling (Pounds)32 billion
  substantially in the form of debt credits in order to enable Names to meet
  their obligations by reinsuring their outstanding liabilities into Equitas,
  (iii) assistance to Names by the release in 1996 profits from the 1994 and
  1995 years of account, and (iv) the creation of a new Central Fund to provide
  security to insureds in respect of business underwritten after 1992.  Various
  London Market companies also have made substantial changes in their
  operations.

     The Company's current business strategy depends to a significant degree
  upon the effective functioning of the London Market, which the Company
  believes is substantially affected by the ability of Lloyd's and the London
  Market companies to provide capacity and by the market's perception of Lloyd's
  and the London Market companies generally.  In addition, the Company has
  substantial relationships with Lloyd's, both in connection with the
  underwriting of insurance and reinsurance and with the purchase of
  reinsurance.  The Company also owns Octavian, a Lloyd's managing agent, and,
  through Terra Nova Capital, provides capacity

                                       9
<PAGE>
 
  to the Octavian Syndicates.  The Company also participates in contracts of
  insurance and reinsurance on a subscription basis with other companies and
  other Lloyd's syndicates.  Because Lloyd's syndicates represent approximately
  half of the capacity for international insurance and reinsurance in the London
  Market, there is a dependence within the London Market upon the capacity of
  Lloyd's in order to maintain the London Market's global capacity and,
  therefore, its ability to provide a major source of capacity for such
  business. If future problems at Lloyd's were to result in significant
  contraction of its capacity, although London Market companies, including the
  Company, would be presented with opportunities to increase participations on
  desirable risks, less insurance business could be offered in the London Market
  and, therefore, less may be available to Terra Nova.  The Company has
  purchased and continues to purchase a portion of its reinsurance protection
  from Lloyd's and to that extent has a dependence on Lloyd's.  At December 31,
  1996, approximately 10% of the Company's present reinsurance program (measured
  by premiums ceded for the 1996 underwriting year) is placed at Lloyd's.  The
  Company has never experienced a failure by Lloyd's to pay reinsurance balances
  ultimately determined to be due.

     Should the Plan of Reconstruction fail, the consequences with respect to
  London Market companies generally could adversely affect the Company by making
  the London Market less attractive to insureds, by damaging the Company's
  ability to obtain or recover on reinsurance or by reducing opportunities
  available to the Company and the Octavian Syndicates to write new business in
  the London Market.

  REINSURANCE AND RETROCESSIONS

     The Company purchases reinsurance primarily to manage exposures in its
  insurance and reinsurance businesses.  The ability of the Company to maintain
  its reinsurance programs in the future on acceptable terms is an important
  factor for the Company's prospects for profitability and growth.  Changes in
  the London Market and U.S. and international reinsurance markets affecting
  reinsurance and retrocessional capacity may have an adverse effect on the
  Company's reinsurance programs and therefore on its own programs and
  prospects.

     The Company has endeavored, and will in the future endeavor, to obtain
  reinsurance only from financially sound reinsurers.  Similar to other
  companies in the insurance industry, the Company has had and is experiencing
  difficulties in obtaining full recovery from some of its reinsurers.  The
  Company maintains a reserve for doubtful debts (totaling $34.4 million at
  December 31, 1996, including aviation business in run-off) in respect of those
  reinsurers in liquidation and/or under schemes of arrangement, or with which
  the Company is in dispute over the amount of recovery due or with respect to
  which the Company has concerns over the reinsurers' ability or willingness to
  pay future recoveries in full.  At December 31, 1996, estimated total
  reinsurance recoverables on paid losses and unpaid losses and LAE (including
  IBNR), were $400.5 million, including aviation business in run-off.  There can
  be no assurance that the Company will not experience further difficulties in
  the future in recovering under its reinsurance and retrocession facilities
  should one or more of its reinsurers suffer financial deterioration.  The
  Company is subject to credit risks with respect to its reinsurers, as the
  ceding of risk to reinsurers does not relieve the ceding company of its
  primary liability to its insureds and reinsureds.  There can be no assurance
  that the reinsurance and retrocession protection purchased by the Company will
  be sufficient to protect the Company from a severe deterioration in the
  frequency or severity of losses or against unusual or catastrophic
  circumstances.  The Company has in the past obtained a significant portion of
  its reinsurance from Lloyd's syndicates.  At December 31, 1996, the Company
  had $133.3 million, including aviation business in run-off, of reinsurance
  recoverables on unpaid losses and LAE (including IBNR) from Lloyd's
  syndicates, which represented 38.6% of the Company's total reinsurance
  recoverables on unpaid losses and LAE (including IBNR) at such date.  Overdue
  balances from

                                       10
<PAGE>
 
  Lloyd's syndicates in respect of reinsurance recoverables are insignificant
  and no specific provision for doubtful debts has been considered necessary by
  the Company in respect of Lloyd's syndicates to date.

     There can be no assurance that Lloyd's syndicates or reinsurance companies
  will continue to provide reinsurance coverage in the future for the Company at
  acceptable rates or that the types of reinsurance purchased by the Company
  will continue to be available from Lloyd's syndicates.  In either of these
  events, the Company would be required to:  (i) find replacement coverage which
  could be more expensive than its current coverage; (ii) reduce its level of
  reinsurance coverage (and accordingly retain a greater percentage of the risk
  underwritten); and/or (iii) reduce the amount of business it writes in one or
  more lines.

  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) in connection with the
  Terra Nova Acquisition, 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.

     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 Untied 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

                                       11
<PAGE>
 
  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.

  POSSIBLE CONFLICTS OF INTEREST

     The DLJ Entities (including Donaldson, Lufkin & Jenrette Securities
  Corporation ("DLJSC"), one of the Underwriters) beneficially own an aggregate
  of 11.7% of the outstanding voting shares of the Company.  As a result of
  their ownership of shares, the DLJ Entities will be able to exercise
  significant influence over the Company through their ability to influence the
  election of directors and other corporate actions requiring shareholder
  approval.

     The DLJ Entities have made, and in the future may seek to make, investments
  in other insurance concerns, and have acquired or invested in, and may in the
  future seek to acquire or invest in, companies that compete with the Company
  in its reinsurance and insurance businesses.  Additionally, certain
  shareholders of the Company have ownership interests in other London Market or
  Bermuda Market companies.  Also, certain directors of the Company are
  employees of certain shareholders of the Company.  As a result, possible
  conflicts of interest could arise between the Company and the foregoing
  parties in the future.  Management anticipates that any future transactions to
  which the Company is a party and which involve the potential for significant
  conflicts of interest will be submitted to the independent directors for their
  approval.  Management

                                       12
<PAGE>
 
  does not believe that there have been any material transactions involving
  parties with a conflict of interest which have been on terms less favorable
  than those which could have been obtained from an independent party.

  NO ACTIVE PUBLIC MARKET FOR THE SENIOR NOTES

     The Senior Notes are listed on the NYSE; however, there can be no assurance
  that an active public market will develop for the Senior Notes.  The
  underwriters in the offering of the Senior Notes have advised the Company that
  they currently intend to make a market in the Senior Notes; however, they are
  not obliged to do so and any market making may be discontinued at any time.
  Accordingly, no assurance can be given as to the prices or liquidity of the
  Senior Notes.  The Senior Notes may trade at prices that may be higher or
  lower than the initial offering price depending upon many factors, including
  general economic conditions, the Issuer's and Bermuda Holdings' financial
  results, government legislation or regulation, and the markets 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 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.

  CHANGE OF CONTROL

     Upon the occurrence of a Change of Control, the Issuer or Bermuda Holdings
  will be required, subject to certain conditions, to offer to purchase all
  outstanding Senior Notes at a price equal to 101% of the principal amount
  thereof, plus accrued interest to the date of purchase.  In certain
  circumstances, a highly leveraged transaction, reorganization, restructuring,
  merger, or similar transaction by certain of the current beneficial owners of
  the voting capital stock of Bermuda Holdings would not constitute a Change of
  Control.  Neither the Issuer nor Bermuda Holdings expect to have sufficient
  funds available to purchase all of the outstanding Senior Notes were they to
  be tendered in response to an offer made as a result oaf a Change of Control.
  There can be no assurance that the Issuer or Bermuda Holdings would be able to
  obtain such funds through dividends from their respective subsidiaries or a
  refinancing of the Senior Notes to be repurchased or otherwise.  In addition,
  although  neither the Issuer nor Bermuda Holdings currently has any senior
  indebtedness outstanding,

                                       13
<PAGE>
 
  provisions in future senior indebtedness of the Issuer or Bermuda Holdings may
  restrict such a purchase and have the effect of delaying or prohibiting the
  Issuer or Bermuda Holdings from commencing an offer to purchase the Senior
  Notes.  Also, the requirement that the Issuer or Bermuda Holdings offer to
  repurchase the Senior Notes in the event of a Change of Control may have the
  effect of deterring a third party from effecting a transaction that would
  constitute a Change of Control.  In addition, a holder of Senior Notes may not
  be able to readily determine if the sale or transfer of substantially all of
  the assets of Bermuda Holdings to certain persons constitutes a Change of
  Control under the Indenture because the term "substantially all" is not
  defined in the Indenture and its meaning under New York law is uncertain.  See
  "Description of Senior Notes -- Purchase at the Option of Holders upon a
  Change of Control" and "--Certain Definitions."

                          DESCRIPTION OF CAPITAL STOCK

  GENERAL

     The Company's authorized share capital consists of 75,000,000 Class A
  Ordinary Shares, par value $5.80 per share, 10,000,000 Class B Ordinary
  Shares, par value $5.80 per share, and 25,000,000 preferred shares, par value
  $1.00 per share (the "Preference Shares").  As at March 1, 1997, 23,804,626
  Class A Ordinary Shares and 2,048,140 Class B Ordinary Shares were issued and
  outstanding.  No Preference Shares were issued or outstanding.  All
  outstanding Ordinary Shares are validly issued, fully paid and nonassessable.
  The following description of the capital stock of the Company does not purport
  to be complete and is subject to, and is qualified in its entirety by, all the
  provisions of the Bye-Laws and the Certificate of Designation of the
  Preference Shares (the "Certificate of Designation"), including the
  definitions therein of certain terms.  Copies of the Bye-Laws and the
  Certificate of Designation have been filed as exhibits to the Registration
  Statement of which this Prospectus constitutes a part.

     The Bye-Laws provide for the corporate governance of the Company, including
  the establishment of share rights, modification of such rights, issuance of
  share certificates, the transfer of shares, alterations to capital, the
  calling and conduct of general meetings, proxies, the appointment and removal
  of directors, conduct and powers of directors, the payment of dividends, the
  appointment of an auditor and the winding-up of the Company.

  ORDINARY SHARES

     The Ordinary Shares rank, as to assets, dividends and in all other respects
  on parity with each other, except that, subject to the limitations on voting
  described below, Class A Ordinary Shares have one vote per share and Class B
  Ordinary Shares have no voting rights.  Matters presented to shareholders for
  approval are approved by a simple majority vote.

     The Ordinary Shares have no preemptive rights or other rights to subscribe
  for additional Ordinary Shares and have no rights of redemption or conversion
  or exchange rights, except that, subject to certain terms and conditions
  contained in the Bye-Laws, the Class B Ordinary Shares are convertible at the
  option of the holder into Class A Ordinary Shares.

     In the event of a liquidation, dissolution or winding-up of the Company,
  the holders of Ordinary Shares are entitled to share equally and ratably in
  the assets of the Company, if any, remaining after the payment of all debts
  and liabilities of the Company and the liquidation preference of any
  outstanding Preference Shares. Authorized but unissued shares may, subject to
  any rights attaching to existing preference and other shares,

                                       14
<PAGE>
 
  be issued at any time and at the discretion of the Board without the approval
  of the shareholders of the Company with such rights, preferences and
  limitations as the Board may determine.

  LIMITATION ON VOTING RIGHTS

     The Bye-Laws contain certain provisions that limit the voting rights that
  may be exercised by certain holders of Class A Ordinary Shares.  These
  provisions are intended to prevent shareholders from certain adverse
  consequences under the "controlled foreign corporation" rules under the U.S.
  Internal Revenue Code of 1986, as amended (the "Code"), although no assurance
  can be given that such provisions will in fact effectively prevent such
  consequences.  Under these provisions, if, and so long as, any U.S. Owner (as
  defined below) directly, indirectly or constructively owns, within the meaning
  of Section 958 of the Code, shares having more than 9.9% of the total number
  of votes exercisable in respect of all shares of voting stock of the Company,
  the voting rights attributable to such shares will be limited, in the
  aggregate, to 9.9% of the total number of votes.  "U.S. Owner" means any U.S.
  Person that directly or indirectly owns, within the meaning of Section 958(a)
  of the Code, any shares of capital stock of the Company, and "U.S. Person" has
  the same meaning as set out in Section 7701(a)(30) of the Code and includes
  (i) a citizen or resident of the United States, (ii) a domestic partnership,
  (iii) a domestic corporation, and (iv) any estate or trust (other than a
  foreign estate or foreign trust).

     The Company is authorized to request information from any holder of Class A
  Ordinary Shares as necessary to give effect to the limitation on voting rights
  described above, and may disregard the votes attached to the Class A Ordinary
  Shares of any holder from whom information is requested until such time as a
  satisfactory response has been received.

  RESTRICTIONS ON TRANSFER; ABILITY TO REPURCHASE

     The Bye-Laws contain several provisions restricting the transferability of
  Class A Ordinary Shares.  The directors are required to decline to register a
  transfer of shares of capital stock of the Company if they have reason to
  believe that as a result of such transfer any U.S. Owner would directly,
  indirectly or constructively own, within the meaning of Section 958 of the
  Code, shares having more than 9.9% of the votes of the Company (without giving
  effect to the limitation on voting rights described above) exercisable in
  respect of all shares of voting stock of the Company.  Similar restrictions
  apply to the Company's ability to issue shares of capital stock of the
  Company.

     The directors also may, in their absolute discretion, decline to register
  the transfer of any shares of capital stock of the Company if they have reason
  to believe (i) that such transfer may expose the Company, any subsidiary
  thereof or any shareholder to adverse tax, legal or regulatory treatment, or
  would be in breach of any applicable legal or regulatory requirements, in each
  case in any jurisdiction, including the Lloyd's Act and Bye-Laws and other
  laws and regulations governing Lloyd's and members of Lloyd's, or (ii) that
  registration of such transfer under the Securities Act or any U.S. state
  securities laws or under the laws of any other jurisdiction is required and
  such registration has not been duly effected.  The Board of Directors may
  exercise such right in connection with, among other things, an acquisition by
  any person of shares of capital stock of the Company which would cause such
  person to be a "controller" of the Company under Lloyd's Corporate Members
  Bye-Laws (presently a 30% shareholder) or to be a "controller" of the Company
  under Lloyd's Underwriting Agents Bye-Laws (presently a 25% shareholder) or
  which cause any Lloyds broker or person "associated" with a Lloyd's broker to
  be "associated" with the Company under the Lloyd's Act (presently a more than
  5% shareholder).

                                       15
<PAGE>
 
     The Company is authorized to request information from any holder or
  prospective acquiror of Class A Ordinary Shares as necessary to give effect to
  the transfer and issuance restrictions described above, and may decline to
  effect any such transaction if complete and accurate information is not
  received as requested.

     Conyers, Dill and Pearman, Bermuda counsel to the Company, have advised the
  Company that while the precise form of the restrictions on transfer contained
  in the Bye-Laws is untested, as a matter of general principle, restrictions on
  transfers are enforceable under Bermuda law and are not uncommon.  The
  transferor of such Class A Ordinary Shares will be deemed to own such Class A
  Ordinary Shares for dividend, voting and reporting purposes until a transfer
  of such Class A Ordinary Shares has been registered on the Register of Members
  of the Company.

     If the directors refuse to register a transfer for any reason, they must
  notify the proposed transferor and transferee within thirty days of such
  refusal.  The Bye-Laws also provide that the Board may suspend the
  registration of transfers for any reason and for such periods as the Board may
  determine, provided that they may not suspend the registration of transfers
  for more than 45 days in any period of 365 consecutive days.

     The directors may designate the Company's Chairman of the Board to exercise
  their authority to decline to register transfer or to limit voting rights as
  described above, or to take any other action, for as long as such officer is
  also a director.

     Notwithstanding the foregoing, the Bye-Laws provide that the transfer
  restrictions described above shall not preclude the settlement of any
  transaction entered into through the facilities of the NYSE.  In the event
  that a person becomes or attempts to become, through a transfer over the NYSE
  or otherwise, the owner of shares of capital stock of the Company, the
  transfer of which would violate the restrictions described above (such shares
  being referred to as the "Restricted Shares"), such person (the "purported
  owner") shall not obtain any rights in the Restricted Shares, the transfer
  agent shall not recognize the transfer of such shares to the purported owner,
  and such shares shall be deemed as of the date of the purported transfer to
  have been transferred to one or more charitable organizations selected by the
  directors.  The charitable organizations shall be entitled to exercise all
  rights incident to ownership of such shares, including without limitation, the
  right to vote such shares and to receive dividends or distributions in respect
  thereof.  A trustee appointed to act as agent for the charitable organizations
  shall be required under the Bye-Laws to take all lawful actions to cause the
  purported owner of the Restricted Shares to deliver such shares to the
  trustee, which shall, upon obtaining possession of the Restricted Shares, sell
  such shares to a person permitted to acquire such shares in accordance with
  the Bye-Laws.  The net proceeds from any such sale of Restricted Shares shall
  first be paid to the purported owner of such shares, in an amount up to the
  amount paid by such purported owner for such shares, and the remaining
  proceeds, if any, shall be paid to the charitable organizations selected by
  directors.

     The Bye-Laws also provide that if the Board in its absolute discretion
  determines that share ownership by any shareholder may result in adverse tax,
  regulatory or legal consequences to the Company, any of its subsidiaries or
  any other shareholder, then the Company will have the option, but not the
  obligation, to repurchase all or part of the shares of capital stock of the
  Company held by such shareholder to the extent the Board determines it is
  necessary to avoid such adverse consequences.  The price to be paid for such
  shares will be the fair market value of such shares.

  PREFERENCE SHARES

     Pursuant to the Bye-Laws and Bermuda law, the Board by resolution may
  establish one or more series of Preference Shares having such number of shares
  (not exceeding 25,000,000), designation, relative voting

                                       16
<PAGE>
 
  rights, dividend rates, liquidation and other rights, preferences and
  limitations as may be fixed by the Board without any further shareholder
  approval.  Such rights, preferences, powers and limitations as may be
  established could also have the effect of discouraging an attempt to obtain
  control of the Company.

  DIVIDENDS

     Subject to the preferences applicable to the Preference Shares, the holders
  of Ordinary Shares will be entitled to receive such dividends, if any, as may
  be declared thereon by the Board at any time and from time to time out of any
  funds of the Company legally available for such purposes.

  BOARD OF DIRECTORS

     The Bye-Laws provide that the Board shall be elected annually and shall not
  be staggered.  Shareholders may only remove a director for cause prior to the
  expiration of such director's term at a special meeting of shareholders at
  which a majority of the holders of shares entitled to vote thereon vote in
  favor of such action.

  TRANSFER AGENT

     The Company's registrar and transfer agent for the Class A Ordinary Shares
  is Chemical Mellon Shareholder Services.

  THE ISSUER

   GENERAL

     The Issuer's authorized share capital consists of 8,400,000,000 A ordinary
  shares, par value U.S. $0.01 per share (the "Issuer A Ordinary Shares"),
  1,500,000,000 B ordinary shares, par value U.S. $0.01 per share (the "Issuer B
  Ordinary Shares" and, together with the Issuer A Ordinary Shares, the "Issuer
  Ordinary Shares"), 100,000,000 convertible preference shares, par value U.S.
  $0.01 per share (the "Issuer Preference Shares"), and 50,000 deferred shares,
  par value (Pounds)l.00 per share (the "Issuer Sterling Deferred Shares").  As
  of December 31, 1996, 808,037,920 Issuer A Ordinary Shares and 50,000 Issuer
  Sterling Deferred Shares were issued and outstanding.  No Issuer B Ordinary
  Shares or Issuer Preference Shares have been issued.  All outstanding Issuer A
  Ordinary Shares and Issuer Sterling Deferred Shares are validly issued, fully
  paid and nonassessable.  The following description of the capital stock of the
  Issuer does not purport to be complete and is subject to, and is qualified in
  its entirety by, all of the provisions of the Memorandum of Association (the
  "Memorandum") and the Articles of Association (the "Articles") of the Issuer,
  including the definitions therein of certain terms.  Copies of the Memorandum
  and the Articles are filed as exhibits to the Registration Statement of which
  this Prospectus forms a part.

   ORDINARY SHARES

     The Issuer Ordinary Shares rank, as to assets, dividends and in all other
  respects, on parity with each other, except with respect to voting rights.
  The Issuer A Ordinary Shares entitle each holder thereof to one vote per share
  held, and Issuer B Ordinary Shares entitle the holder thereof to one vote for
  every ten Issuer B Ordinary Shares held.  The Issuer Ordinary Shares have no
  rights of redemption or conversion or exchange rights.

                                       17
<PAGE>
 
   PREFERENCE SHARES

    The Issuer Preference Shares rank senior as to all other capital stock of
  the Issuer with respect to dividend payments and liquidation.  Subject to
  certain terms and conditions contained in the Articles, the Issuer Preference
  Shares are convertible at any time at the option of the holders thereof into,
  at the discretion of the board of directors of the Issuer, either Issuer B
  Ordinary Shares or Issuer B Ordinary Shares and deferred shares, par value
  U.S. $0.01 per share (the "Issuer U.S. $ Deferred Shares").  Holders of Issuer
  U.S. $ Deferred Shares will have liquidation rights; however, they will not
  have dividend or voting rights.

   STERLING DEFERRED SHARES

     The Issuer Sterling Deferred Shares have no dividend or voting rights or
  any other rights, except certain limited rights upon liquidation.

   DIVIDENDS

     Subject to the special rights attaching to the Issuer Preference Shares,
  the holders of Issuer Ordinary Shares will be entitled to receive such
  dividends, if any, as may be declared thereon by the board of directors of the
  Issuer out of the profits of the Issuer available for distribution.  Dividends
  on the Issuer Preference Shares are cumulative.  Dividends on the Issuer
  Preference Shares are payable on the Liquidation Value (as defined in the
  Articles) as at the immediately preceding due date for payment of the dividend
  at the rate of 5% semi-annually.  Dividends on the Issuer Preference Shares
  accrue from day to day and are payable on June 30 and December 31 of each
  year.

                          DESCRIPTION OF SENIOR NOTES

  GENERAL

     The Senior Notes constitute senior unsecured obligations of the Issuer
  issued pursuant to the Indenture (the "Indenture") among the Issuer, Bermuda
  Holdings and The Chase Manhattan Bank, N.A., as trustee (the "Trustee").  The
  terms of the Senior Notes include those stated in the Indenture and those made
  part of the Indenture by reference to the Trust Indenture Act of 1939, as
  amended (the "Trust Indenture Act").  The Senior Notes are subject to all such
  terms, and holders of Senior Notes are refer-red 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.  A copy of the form of Indenture has been
  filed as an exhibit to the Registration Statement of which this Prospectus is
  a part.  The following description of the terms of the Senior Notes and the
  guarantee thereof by Bermuda Holdings pursuant to the Indenture or pursuant to
  guarantees endorsed on the Senior Notes (both forms of guarantee are
  hereinafter referred to collectively as the "Guarantee") sets forth certain
  terms and provisions of the Senior Notes and the Guarantee.  The definitions
  of certain general terms used in the following summary are set forth below
  under "--Certain Definitions."

     The Senior Notes 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 Senior
  Notes are fully and unconditionally guaranteed on a senior basis by Bermuda
  Holdings, and the obligations of Bermuda Holdings under the Guarantee rank
  senior in right of payment to all subordinated indebtedness of

                                       18
<PAGE>
 
  Bermuda Holdings and pari passu in right of payment with all indebtedness of
  Bermuda Holdings not expressly subordinated or secured.

     The Senior Notes were initially be issued as the Global Note, which was
  deposited with the Custodian, as custodian thereof for the Depositary,
  pursuant to the Deposit and Custody Agreement (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 issued the Global Receipt, which was delivered to
  and registered in the name of DTC or its nominee.  Unless and until all of the
  beneficial interests in the Global Note ("Book-Entry Interests") are exchanged
  for Definitive Senior Notes (as defined herein), 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.

     The Senior Notes are listed on the NYSE.

  GUARANTEE

     Bermuda Holdings has fully and unconditionally guaranteed on a senior basis
  to each holder of a Senior Note the due and punctual payment of the principal
  of and any premium and interest on such Senior Note (and any Additional
  Amounts (as defined herein) payable by the Issuer or Bermuda Holdings in
  respect thereof) when and as the same shall become due and payable, whether at
  stated maturity, by declaration of acceleration, call for redemption or
  otherwise, in accordance with the terms of the Senior Notes and the Indenture.
  Bermuda Holdings' obligations under the Guarantee are as if it were a
  principal debtor and not merely a surety, and are absolute and unconditional,
  irrespective of, and will be unaffected by, any invalidity, irregularity or
  unenforceability of any Senior Note or the Indenture, any failure to enforce
  the provisions of any Senior Note or the Indenture, any waiver, modification
  or indulgence granted to the Issuer with respect thereto, by the holder of any
  Senior 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 a Senior 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 $100.0
  million.  The Senior Notes will mature on July 1, 2005.  Interest on the
  Senior Notes accrues at the rate of 10 3/4% per annum and is payable semi
  annually in arrears in cash on each January 1 and July 1, commencing January
  1, 1996 (each, an "Interest Payment Date"), to holders of record on the
  immediately preceding December 15 and June 15, respectively. Interest on the
  Senior Notes accrues from the most recent date to which interest has been paid
  or, if no interest has been paid, from the original date of issuance.
  Interest is computed on the basis of a 360-day year of twelve 30-day months.

  OPTIONAL REDEMPTION

     Except as provided in the next two paragraphs, the Senior Notes will not be
  redeemable at the Issuer's option prior to July 1, 2000.  Thereafter, the
  Senior Notes will be redeemable, at the option of the Issuer, in whole at any
  time or in part from time to time, upon not less than 30 nor more than 60
  days' notice, at the redemption prices (expressed as percentages of principal
  amount) set forth below, together with accrued and

                                       19
<PAGE>
 
  unpaid interest thereon to the applicable redemption date, if redeemed during
  the 12-month period beginning on July 1, of the years indicated below:
<TABLE>
<CAPTION>
 
                YEAR                     PERCENTAGE
                ----                     ---------- 
                <S>                      <C>
                2000....................  104.031%
                2001....................  102.688%
                2002....................  101.344%
                2003 and thereafter.....  100.000%
</TABLE>

            At any time prior to July 1, 1998, the Issuer may redeem up to 35%
  of the aggregate principal amount of the Senior Notes originally issued with
  the net proceeds of one or more offerings of Capital Stock (other than
  Redeemable Capital Stock) of Bermuda Holdings or the Issuer, in each case at a
  redemption price equal to 109.75% of the principal amount thereof, plus
  accrued and unpaid interest to the redemption date; provided that (i) at least
  $65.0 million in aggregate principal amount of the Senior Notes originally
  issued remains outstanding immediately after the occurrence of any such
  redemption, (ii) any such redemption occurs within 90 days of the date of the
  closing of any such offering; and (iii) the Issuer may conduct no more than
  one redemption per offering of such Capital Stock.

  TAX REDEMPTION

     The Senior Notes may 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 the
  principal amount thereof plus 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 the NYSE
  or other principal national securities exchange, if any, on which the Senior
  Notes are listed or,

                                       20
<PAGE>
 
  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.

  PURCHASE AT THE OPTION OF HOLDERS UPON A CHANGE OF CONTROL

     Upon the occurrence of a Change of Control, the Issuer or Bermuda Holdings
  will be required to make an offer (a "Change of Control Offer") to each holder
  of Senior Notes to repurchase all or any part (equal to $1,000 or an integral
  multiple thereof) of such holder's Senior Notes at a purchase price equal to
  101% of the aggregate principal amount thereof plus accrued and unpaid
  interest thereon to the date of purchase (a "Change of Control Payment").
  Within 15 days following the date on which a Change of Control occurs, the
  Issuer or Bermuda Holdings shall mail a notice to each holder of Senior Notes
  stating:  (a) that a Change of Control Offer is being made pursuant to the
  covenant entitled "Purchase at the Option of Holders upon a Change of Control"
  and that all Senior Notes properly tendered will be accepted for payment; (b)
  the purchase price and the purchase date, which shall be no earlier than 30
  days nor later than 60 days from the date such notice is mailed (the "Change
  of Control Payment Date"); (c) that any Senior Notes not properly tendered
  will continue to accrue interest in accordance with the terms of the
  Indenture; (d) that, unless the Issuer or Bermuda Holdings defaults in the
  payment of a Change of Control Payment, all Senior Notes accepted for payment
  pursuant to a Change of Control Offer shall cease to accrue interest after the
  Change of Control Payment Date; (e) that holders of Senior Notes electing to
  have any Senior Notes purchased pursuant to a Change of Control Offer will be
  required to surrender the Senior Notes (to the extent held as Definitive
  Senior Notes), with the form entitled "Option of Holder to Elect Purchase" on
  the reverse of the Senior Notes completed, or transfer by book-entry, to the
  paying agent at the address specified in the notice prior to the close of
  business on the third Business Day preceding the Change of Control Payment
  Date; (f) that holders of Senior Notes will be entitled to withdraw their
  election if the paying agent receives, not later than the close of business on
  the second Business Day preceding the Change of Control Payment Date, a
  telegram, telex, facsimile transmission or letter setting forth the name of
  the holder, the principal amount of Senior Notes delivered for purchase, and a
  statement that such holder is withdrawing his election to have such Senior
  Notes purchased; and (g) that holders of Senior Notes whose Senior Notes are
  being purchased only in part will be issued new Senior Notes equal in
  principal amount to the unpurchased portion of the Senior Notes surrendered,
  which unpurchased portion must be equal to $1,000 in principal amount or an
  integral multiple thereof.  The Issuer or Bermuda Holdings will comply with
  the requirements of Rule 14e-1 under the Exchange Act and any other securities
  laws and regulations thereunder to the extent such laws and regulations are
  applicable in connection with the repurchase of the Senior Notes in connection
  with a Change of Control.

     On the Change of Control Payment Date, the Issuer or Bermuda Holdings will,
  to the extent lawful, (a) accept for payment all Senior Notes or portions
  thereof properly tendered pursuant to a Change of Control Offer, (b) deposit
  with the paying agent an amount equal to a Change of Control Payment in
  respect of all Senior Notes or portions thereof so tendered and (c) deliver or
  cause to be delivered to the Trustee the Senior Notes so accepted together
  with an officers' certificate stating the aggregate principal amount of Senior
  Notes

                                       21

  or portions thereof being purchased by the Issuer or Bermuda Holdings;
  provided that neither the Issuer nor Bermuda Holdings will be obligated to
  purchase Senior Notes following a Change of Control if holders of less than
  25% in aggregate principal amount of Senior Notes then outstanding have
  tendered such Senior Notes in a Change of Control Offer.  The paying agent
  will promptly mail to each holder of Senior Notes so tendered a Change of
  Control Payment for such Senior Notes, and the Trustee will promptly
  authenticate and mail (or cause to be transferred by book-entry) to each
  holder a new Senior Note equal in principal amount to any unpurchased portion
  of the Senior Notes surrendered, if any; provided that each such new Senior
  Note will be in a principal amount of $1,000 or an integral multiple thereof.
  The Issuer or Bermuda Holdings will publicly announce the results of a Change
  of Control Offer on or as soon as practicable after a Change of Control
  Payment Date.

         Restricted Payment and after giving effect thereto:

         (A) no Default or Event of Default shall have occurred and be
             continuing or would occur as a consequence thereof, and

         (B) Bermuda Holdings, after giving pro forma effect to such Restricted
             Payment, would be permitted to incur at least $1.00 of additional
             Indebtedness (other than Permitted Indebtedness) pursuant to the
             Consolidated Fixed Charge Coverage Ratio test set forth in the
             covenant described under "-- Limitation on Indebtedness" below; and

         (C) such Restricted Payment, together with the aggregate of all other
             Restricted Payments declared or made by Bermuda Holdings and its
             Restricted Subsidiaries after the Issue Date (including

                                       22
<PAGE>
 
             Restricted Payments permitted by paragraph (2) below other than
             Permitted Payments (as defined below)), shall not exceed the sum
             of:

            (a) 50% of the aggregate Consolidated Adjusted Net Income of Bermuda
                Holdings accrued on a cumulative basis during the period (taken
                as a single period) commencing with the fiscal quarter prior to
                the fiscal quarter in which the Issue Date occurs (or, if such
                aggregate cumulative Consolidated Adjusted Net Income shall be a
                loss, minus 100% of such loss); plus

            (b) 100% of the net cash proceeds received after the Issue Date by
                Bermuda Holdings (other than from any of its Subsidiaries) or
                the Issuer (other than from any of its Subsidiaries) as capital
                contributions to Bermuda Holdings or the Issuer, as applicable,
                or from the sale or issuance of Capital Stock (other than
                Redeemable Capital Stock) of Bermuda Holdings; plus

            (c) 100% of the net cash proceeds received by Bermuda Holdings after
               the Issue Date (other than from any of its Subsidiaries) from the
               exercise of options or warrants to purchase Capital Stock of
               Bermuda Holdings; plus

            (d) 100% of the net cash proceeds received by Bermuda Holdings after
                the Issue Date (other than from any of its Subsidiaries) from
                the issuance and sale of convertible indebtedness or convertible
                preferred stock issued after the Issue Date but only to the
                extent such indebtedness or preferred stock has been converted
                into Capital Stock (other than Redeemable Capital Stock); plus

            (e)  $5.0 million.

       Notwithstanding the foregoing, Bermuda Holdings will not, and will not

     Capital Stock of Bermuda Holdings or any Subsidiary of Bermuda Holdings

     Owned Restricted Subsidiary of Bermuda Holdings, unless and until Bermuda
     Holdings or the Issuer shall have successfully completed a registered
     public offering of its Capital Stock (other than Redeemable Capital Stock
     or Preferred Stock);

     (2) Notwithstanding the foregoing, Bermuda Holdings and its Restricted
         Subsidiaries may take the following actions (clauses (ii), (iii), (iv),
         (v), (vii) and (viii) below being referred to as "Permitted Payments")
         so long as, in the case of clauses (iii), (iv), (vi), (vii) and (viii),
         no Default or Event of Default has occurred and is continuing:

        (i)   the payment of any dividend within 60 days after the date of
              declaration thereof, if at such declaration date such declaration
              complied with the provisions of paragraph (1) above (in which
              event such dividend shall be deemed to have been paid on such date
              of declaration thereof for purposes of paragraph (1) above);

       (ii)   the consummation of the transactions contemplated by the Put
              Agreements (other than any payment in cash pursuant thereto);

              retirement for value of any shares of Capital Stock of Bermuda
              Holdings or any Subordinated Indebtedness (A) in exchange for or
              out of the net cash proceeds of a substantially concurrent issue
              and sale (other

                                       23
<PAGE>
 
              than to Bermuda Holdings or a Subsidiary of Bermuda Holdings) of
              shares of Capital Stock (other than Redeemable Capital Stock) of
              Bermuda Holdings or (B) out of the net cash proceeds of a
              substantially concurrent additional capital contribution to
              Bermuda Holdings; provided that, in the case of both clauses (A)
              and (B), the net proceeds of any such issuance, sale or capital
              contribution are excluded from clauses (b), (c) and (d) of
              paragraph (1)(C) above;

       (iv)   the repurchase, redemption, defeasance or other acquisition or
              retirement for value of any Subordinated Indebtedness of Bermuda
              Holdings in exchange for or out of the net cash proceeds of a
              substantially concurrent issue and sale (other than to Bermuda
              Holdings or a Subsidiary of Bermuda Holdings) of new Indebtedness
              of Bermuda Holdings; provided that any such new Indebtedness (A)
              shall be in a principal amount (plus the amount of fees and
              expenses incurred in connection with such refinancing) that does
              not exceed the principal so refinanced; provided, further, that
              for purposes of this clause (A), the principal amount of any
              Indebtedness shall be deemed to mean the principal amount thereof
              or, if such Indebtedness provides for an amount less than the
              principal amount thereof to be due and payable upon a declaration
              of acceleration thereof, such lesser amount as of the date of
              determination; (B) shall not have an Average Life or final Stated
              Maturity of principal less than the Indebtedness so refinanced;
              and (C) shall be subordinate to the Senior Notes at least to the
              extent and in the manner that the Indebtedness to be refinanced is
              subordinate to the Senior Notes;

       (v)    payment of the Deferred Payment Right;

       (vi)   the repurchase, redemption or other acquisition or retirement for
              value of an aggregate of up to $3.0 million of securities of
              Bermuda Holdings from members of management of Bermuda Holdings or
              its Restricted Subsidiaries;

       (vii)  declaration and payment of dividends in respect of Bermuda
              Holdings' convertible redeemable preferred shares outstanding on
              the Issue Date; and

       (viii) repayment of any portion of the interim notes or the seller notes
              of the Issuer or any action relating to the surrender or
              cancellation of the preference shares of Bermuda Holdings, Terra
              Nova or Terra Nova (Bermuda), in each case pursuant to the
              provisions of Section 7.2 of the share purchase agreement dated
              December 21, 1994, between the Issuer and the sellers named
              therein.

  All of the actions (i) described in this paragraph (2) other than Permitted
  Payments shall be Restricted Payments which shall be permitted to be made in
  accordance with this paragraph but shall reduce the amount that would
  otherwise be available for Restricted Payments under the test described in
  paragraph (1) and (ii) described as Permitted Payments in this paragraph shall
  be permitted to be made in accordance with this paragraph and shall not reduce
  the amount that would otherwise be available for Restricted Payments under the
  test described in paragraph (1).

     Not later than the date of making any Restricted Payment, the Issuer shall
  deliver to the Trustee an officers' certificate stating that such Restricted
  Payment is permitted and setting forth the basis upon which the calculations
  required by the covenant "Restricted Payments" were computed, which
  calculations may be based upon Bermuda Holdings' latest available financial
  statements.

   LIMITATION ON INDEBTEDNESS

     The Indenture provides that neither Bermuda Holdings nor the Issuer will,
  directly or indirectly, create, incur, assume, guarantee or otherwise become
  directly or indirectly liable for the payment of (collectively, "incur") any
  Indebtedness (including any Acquired Indebtedness) other than Permitted
  Indebtedness unless Bermuda Holdings' Consolidated Fixed Charge Coverage Ratio
  for Bermuda Holdings' most recently ended four full fiscal quarters for which
  financial statements are available immediately preceding the incurrence of
  such Indebtedness, taken as one period, would have been at least equal to 2.75
  to 1.0, determined on a pro forma basis (including a pro forma application of
  the net proceeds therefrom) as if the additional Indebtedness had been
  incurred at the beginning of such four-quarter period.  For purposes of
  calculating this ratio: (i) interest on any Indebtedness under a revolving
  credit facility will be computed on a pro forma basis based upon the average
  daily balance of such indebtedness during the applicable period; and (ii) in
  the event that Bermuda Holdings or any of its Restricted Subsidiaries incurs
  or redeems any Indebtedness, issues or redeems any preferred stock or makes
  any material acquisition or disposition subsequent to the commencement of the
  period for which such ratio is being calculated but prior to the event in
  respect of which such ratio is being calculated, the ratio shall be calculated
  after giving pro forma effect to such incurrence or redemption of
  indebtedness, such issuance or redemption of preferred stock and such material
  acquisition or disposition, as if the same had occurred at the beginning of
  such period.

     The Indenture also provides that Bermuda Holdings will not permit any of
  its Restricted Subsidiaries (other than the Issuer) to incur any Indebtedness
  (including Acquired Indebtedness), other than Permitted Subsidiary
  Indebtedness.

   LIMITATION ON USE OF PROCEEDS FROM ASSET DISPOSITIONS

     The Indenture provides that Bermuda Holdings will not, and will not permit
  any of its Restricted Subsidiaries to, directly or indirectly, consummate any
  Asset Disposition (other than as permitted pursuant to those provisions
  described in "--Merger, Consolidation or Sale of Assets" below, which
  constitutes an Asset Disposition of all or substantially all of Bermuda
  Holdings' assets) unless:  (i) the consideration received from such Asset
  Disposition is at least equal to the fair market value of the property sold
  (which, in the case of any Asset Disposition involving assets having a fair
  market value in excess of $5.0 million (including the value of non-cash
  consideration) must be determined by the Board of Directors of Bermuda
  Holdings); (ii) 75% of the consideration from the Asset Disposition is
  received in cash, Cash Equivalents, other securities listed on a U.S. or
  European national securities exchange or The NASDAQ Stock Market, or the
  assumption of liabilities (other than Subordinated Indebtedness); and (iii)
  Bermuda Holdings applies (or causes a Restricted Subsidiary to apply) the Net
  Available Cash within one year from the later of the date of such Asset
  Disposition or the receipt of such Net Available Cash as follows:  (A) first,
  to the extent Bermuda Holdings elects, to acquire any Insurance Business or to
  invest in its Insurance Business, (B) second, to the extent Bermuda Holdings
  elects, to prepay, repay or purchase any Indebtedness of a Principal Insurance
  Subsidiary (other than Indebtedness owed to Bermuda Holdings or an Affiliate
  of Bermuda Holdings), (C) third, to the extent Net Available Cash exceeds the
  amount applied in accordance with clauses (A) and (B) ("Excess Proceeds"), to
  make an offer to apply the Excess Proceeds, once such Excess Proceeds
  accumulate to a sum greater than $5.0 million, to repurchase the Senior Notes,
  in accordance with the procedures set forth in the Indenture at a purchase
  price equal to 100% of the principal amount of such Senior Notes, plus accrued
  and unpaid interest to the date of purchase and (D) fourth, to the extent
  Excess Proceeds exist after application thereof in accordance with clauses
  (A), (B) and (C), to prepay, repay or purchase any Indebtedness of Bermuda
  Holdings or any Restricted Subsidiary.

                                       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.

   LIMITATION ON BUSINESS ACTIVITIES

     The Indenture provides that Bermuda Holdings will not, and will not permit
  any of its Restricted Subsidiaries to, engage in any business other than:  (i)
  the Insurance Business and such business activities incidental or related
  thereto, including, without limitation, the administration of the insurance
  business and the management of investments (including for unaffiliated third
  parties); (ii) such other businesses related to the Insurance Business as
  Bermuda Holdings or its Restricted Subsidiaries are engaged in on the Issue
  Date but the operation of such businesses shall be limited to the extent of
  business activity conducted on the Issue Date or to the extent appropriate to
  permit the run-off of business existing on the Issue Date or to the extent
  appropriate to manage businesses held for sale until the date of sale, and
  (iii) acting as a holding company for companies engaged in the businesses
  specified in (i) and (ii) above.

   LIMITATION ON SALE OF CAPITAL STOCK OF PRINCIPAL INSURANCE SUBSIDIARIES

     Except for a transaction subject to the provisions of the Indenture
  described below under "--Merger, Consolidation or Sale of Assets," Bermuda
  Holdings will not, and will not permit any Subsidiary to, directly or
  indirectly, sell, transfer, convey or otherwise dispose of (other than to
  Bermuda Holdings or a Wholly-Owned Restricted Subsidiary of Bermuda Holdings)
  any Capital Stock of a Principal Insurance Subsidiary or any securities
  convertible into or warrants, rights or options to subscribe for Capital Stock
  of any Principal Insurance Subsidiary, and Bermuda Holdings will not permit
  any Principal Insurance Subsidiary to issue or sell (other than to Bermuda
  Holdings or a Wholly-Owned Restricted Subsidiary of Bermuda Holdings) any of
  its Capital Stock or securities convertible into or rights, warrants or
  options to subscribe for its Capital Stock. The foregoing restriction shall
  not prohibit consummation of the transactions contemplated by the Put
  Agreements or the issuance or sale by Terra Nova or Terra Nova (Bermuda) of
  its Capital Stock (other than Redeemable Capital Stock) or securities
  convertable into or rights, warrants or options to subscribe for such Capital
  Stock (other than Redeemable Capital Stock) to certain initial investors in
  the Company for cash.

   DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES

     The Indenture provides that Bermuda Holdings will not, and will not permit
  any Restricted Subsidiary to, directly or indirectly, create or otherwise
  cause or suffer to exist or become effective any consensual encumbrance or
  restriction of any kind on the ability of any Restricted Subsidiary to:  (i)
  pay dividends or make any other distributions to Bermuda Holdings or any of
  its Restricted Subsidiaries on its Capital Stock or with respect to any other
  interest or participation in, or measured by, its profits; (ii) pay any
  Indebtedness owed to Bermuda Holdings or any of its Restricted Subsidiaries;
  (iii) make loans or advances to Bermuda Holdings or any of its Restricted
  Subsidiaries; or (iv) transfer any of its properties or assets to Bermuda
  Holdings or any of its Restricted Subsidiaries, except for such encumbrances
  or restrictions existing under or by reason of:

                                       26
<PAGE>
 
     (a) existing Indebtedness as in effect on the date of the Indenture;

     (b) the Indenture, the Senior Notes and the Guarantee;

     (c) any law or any governmental regulation or order or pursuant to any
         agreement or understanding with any regulatory body or agency; provided
         that Bermuda Holdings has used its reasonable efforts to have any such
         order diminished or removed by any regulator authorized to do so and to
         obtain any exemptive orders from the relevant regulator with respect to
         such encumbrance or restriction to the extent such exemptive orders are
         reasonably suitable under applicable laws and regulations;

     (d) any instrument existing on the Issue Date that governs the Preferred
         Stock of any Restricted Subsidiary outstanding on the Issue Date;

     (e) any instrument governing Indebtedness or Capital Stock of a Person
         acquired by Bermuda Holdings or any of its Restricted Subsidiaries as
         in effect at the time of acquisition (except to the extent such
         Indebtedness was incurred in connection with, or in contemplation of,
         such acquisition), which encumbrance or restriction is not applicable
         to any Person, or the properties or assets of any Person, other than
         the Person, or the property or assets of the Person, so acquired;

     (f) customary non-assignment provisions in leases and in agreements
         relating to intellectual property entered into in the ordinary course
         of business and consistent with past practices;

     (g) any agreement with respect to Permitted Subsidiary Indebtedness;
         provided that such encumbrances and restrictions shall not, in the
         reasonable opinion of management of Bermuda Holdings as of the date of
         any such agreement, materially impair the ability of the Issuer to pay
         the principal of and premium and interest on the Senior Notes (and any
         Additional Amounts payable in respect thereof) or the ability of
         Bermuda Holdings to pay under the Guarantee; or

     (h) any agreement that extends, refinances, renews or replaces any
         agreement containing any of the restrictions described in the foregoing
         clauses (a) through (g); provided that the terms and conditions of any
         such encumbrances or restrictions are not materially less favorable to
         the holders of the Senior Notes than those under or pursuant to the
         agreement extended, refinanced, renewed or replaced.

   TRANSACTIONS WITH AFFILIATES

     The Indenture provides that Bermuda Holdings will not, and will not permit
  any of its Restricted Subsidiaries to, directly or indirectly, conduct any
  business or enter into or suffer to exist any transaction (including, without
  limitation, the purchase, sale, transfer, lease or exchange of any assets or
  property or the rendering of any service) with, or for the benefit of, any
  Affiliate of Bermuda Holdings or any of its Subsidiaries other than a Wholly-
  Owned Restricted Subsidiary (each of the foregoing, an "Affiliate
  Transaction"), unless such Affiliate Transaction is on terms that are no less
  favorable to Bermuda Holdings or the relevant Subsidiary, as the case may be,
  than those that could have been obtained in a comparable transaction by
  Bermuda Holdings or such Subsidiary, as the case may be, on an arm's length
  basis from an unrelated person; provided that a transaction with any Affiliate
  of Bermuda Holdings or any of its Subsidiaries that involves services or
  consideration having a value of more than $1.0 million shall only be deemed to
  be on terms no less favorable to Bermuda Holdings or the relevant Subsidiary,
  as the case may be, than those obtainable at the time of the transaction on an
  arm's length basis from an unrelated person if a majority of the

                                       27
<PAGE>
 
  directors of Bermuda Holdings and, if any of the directors are disinterested,
  a majority of the disinterested directors of Bermuda Holdings approves the
  Affiliate Transaction, except that the foregoing proviso shall not apply to
  transactions between Bermuda Holdings or its Restricted Subsidiaries, on the
  one hand, and any Affiliates of Bermuda Holdings or its Restricted
  Subsidiaries, on the other hand, in the ordinary course of business involving
  the insurance or reinsurance of risks or the brokering of insurance or
  reinsurance.  The foregoing restriction shall not apply to:  (i) the payment
  of reasonable and customary regular fees to directors of Bermuda Holdings and
  its Restricted Subsidiaries who are not employees of Bermuda Holdings or its
  Subsidiaries; (ii) loans to officers, directors and employees of Bermuda
  Holdings and its Restricted Subsidiaries for business purposes and other loans
  and advances to such officers, directors and employees for travel,
  entertainment, moving and other relocation expenses made in the ordinary
  course of business of Bermuda Holdings and its Restricted Subsidiaries; (iii)
  any Permitted Payments and any Restricted Payments not prohibited by the
  "Restricted Payments" covenant; (iv) transactions between or among any of
  Bermuda Holdings and its Restricted Subsidiaries; (v) transactions between
  Bermuda Holdings or its Restricted Subsidiaries on the one hand, and any of
  the Underwriters and its Affiliates on the other hand, involving the provision
  of financial, consulting or underwriting services by such Underwriter or its
  Affiliates; provided that the fees payable to such Underwriter or its
  Affiliates do not exceed the usual and customary fees of such Underwriter or
  its Affiliates for similar services; (vi) allocation of corporate overhead by
  Bermuda Holdings to its Restricted Subsidiaries; or (vii) transactions
  effected in accordance with the Tax Sharing Agreement and any amendment to
  such agreement.

   RESTRICTIONS ON ISSUANCE OF PREFERRED STOCK OF SUBSIDIARIES

     The Indenture provides that Bermuda Holdings will not permit any of its
  Restricted Subsidiaries to issue any Preferred Stock, or permit any Person to
  own or hold an interest in any Preferred Stock of any Restricted Subsidiary
  except for:  (i) Preferred Stock outstanding on the Issue Date; (ii) Preferred
  Stock issued upon the exercise of a put right pursuant to any of the Put
  Agreements; and (iii) Preferred Stock issued to Bermuda Holdings or a Wholly-
  Owned Restricted Subsidiary of Bermuda Holdings.

   LIMITATIONS ON ISSUANCE OF GUARANTEES

     The Indenture provides that Bermuda Holdings will not permit any Restricted
  Subsidiary, directly or indirectly, to guarantee or secure any Pari Passu
  Indebtedness or any Subordinated Indebtedness unless such Restricted
  Subsidiary simultaneously executes and delivers a supplemental indenture to
  the Trustee providing for the guarantee of the payment of the Senior Notes by
  such Restricted Subsidiary; provided that, in the case of any Subordinated
  Indebtedness, the guarantee of the Senior Notes is senior to any guarantee of
  such Subordinated Indebtedness.  Notwithstanding the foregoing, any such
  guarantee by a Restricted Subsidiary of the Senior Notes shall provide by its
  terms that it shall be automatically and unconditionally released and
  discharged upon either (i) the release or discharge of such guarantee of
  payment of Pari Passu Indebtedness or any Subordinated Indebtedness, as
  applicable, or (ii) any sale, exchange or transfer, to any Person not an
  Affiliate of Bermuda Holdings, of all of Bermuda Holdings' stock in, or all or
  substantially all the assets of, such Restricted Subsidiary, which sale,
  exchange or transfer is made in compliance with the applicable provisions of
  the Indenture.  The foregoing restriction shall not apply to guarantees given
  by a Restricted Subsidiary in the ordinary course of its insurance business.

   INVESTMENTS

     The Indenture provides that Bermuda Holdings will not, and will not permit
  any of its Restricted Subsidiaries to, make any Investments other than
  Permitted Investments.

                                       28

   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 on a pro forma basis, 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) except in the case where the Surviving Entity is a Wholly-Owned
     Restricted Subsidiary of Bermuda Holdings acquiring or succeeding to all or
     substantially all of Bermuda Holdings' assets, immediately after giving
     effect to such transaction as if such transaction had occurred at the
     beginning of the applicable four-quarter period, Bermuda Holdings (or the
     Surviving Entity if Bermuda Holdings is not the continuing obligor with
     respect to the Guarantee under the Indenture) would be permitted to incur
     at least $1.00 of additional Indebtedness (other than Permitted
     Indebtedness) pursuant to the Consolidated Fixed Charge Coverage Ratio test
     set forth in the covenant described under "--Certain Covenants--Limitation
     on Indebtedness";

                                       29
<PAGE>
 
        (v) 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

       (vi) 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.

     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

                                       30
<PAGE>
 
   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 or any administrative or governmental body):

       (i) default in the payment of interest on any Senior Note when the same
     becomes due and payable and the continuance of such default for a period of
     30 days; or

       (ii) default in the payment of the principal of (or premium, if any, on)
     any Senior Note at its Maturity;

       (iii)  default in the performance, or breach, of any covenant or
     agreement of the Issuer or Bermuda Holdings under the Indenture (other than
     the obligations specified in (i), (ii) and (viii)), and continuance of such
     default or breach for a period of 60 days after there has been given, by
     registered or certified mail, to the Issuer by the Trustee or to the Issuer
     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

                                       31
<PAGE>
 
     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, ten 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 as to which a reputable non-affiliated insurance
     company has accepted full 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 ten days, or (B) a
     period of sixty 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
     similar official) of the Issuer, Bermuda Holdings or any Principal
     Insurance Subsidiary or of any substantial part of any of their properties,
     or ordering the winding up or liquidation of any of their affairs, and any
     such decree or order remains unstayed and in effect for a period of sixty
     consecutive days; or

       (vii)    the Issuer, Bermuda Holdings or any Principal Insurance
     Subsidiary institutes a voluntary case or proceeding under applicable
     bankruptcy, insolvency, reorganization or similar law, or any other case or
     proceedings to be adjudicated a bankrupt or insolvent, or the Issuer,
     Bermuda Holdings or any Principal Insurance Subsidiary files a petition or
     answer or consent seeking reorganization or relief under applicable
     bankruptcy, insolvency, reorganization or similar law, or consents to the
     filing of any such petition or to the appointment of or taking possession
     by a custodian, receiver, liquidator, assignee, trustee, sequestrator (or
     other similar 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
     described under "--Merger, Consolidation or Sale of Assets."

     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

                                       32
<PAGE>
 
  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

                                       33
<PAGE>
 
  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; (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 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.

  TRANSFER AND EXCHANGE

     For information with respect to the transfer of Book-Entry Interests, see
  "Description of Depositary Agreement--Transfers." A holder of Definitive
  Senior Notes may transfer or exchange the Senior Notes in accordance with the
  procedures set forth in the Indenture.  The registrar may require a holder of
  Definitive Senior Notes, among other things, to furnish appropriate
  endorsements and transfer documents, and to pay any taxes and fees required by
  law or permitted by the Indenture.  The registrar is not required to transfer
  or exchange any Definitive Senior Note selected for redemption.  Also, the
  registrar is not required to transfer or exchange any Definitive Senior Note
  for a period of 15 days before a selection of the Definitive Senior Notes to
  be redeemed.

     The registered holder of a Definitive Senior Note will be treated as the
  owner of it for all purposes.

  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, except that
  any amendment to the provisions of the Indenture relating to "Purchase at the
  Option of Holders upon a Change of Control" may be made with the consent of
  not less than 51% of the holders of the outstanding aggregate principal amount
  of the Senior Notes.

     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

  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.

                      DESCRIPTION OF DEPOSITARY AGREEMENT

  GENERAL

     All Senior Notes underlying Book-Entry Interests are represented by the
  Global Note, which has been issued in a denomination equal to the aggregate
  principal amount of outstanding Senior Notes to be represented thereby, and
  has been deposited with the Custodian pursuant to the terms of the Depositary
  Agreement.  The Depositary has issued the Global Receipt (representing a 100%
  interest in the underlying Global Note) which was delivered to and registered
  in the name of DTC or its nominee.  Unless and until all Book-Entry Interests
  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.

     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.

     So long as the Custodian, or its nominee, is the holder of the Global Note
  underlying Book-Entry Interests, the Custodian or such nominee, as the case
  may be, will be considered the sole holder of such 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 Senior Notes in definitive registered form ("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 Note, 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 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 Senior Notes--
  Payment of Additional Amounts," such additional amounts will be paid to or by
  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

                                       49
<PAGE>
 
  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.

     Upon the issuance by the Depositary of the Global Receipt to DTC, DTC
  credited, on its book-entry registration and transfer system, the
  participants' accounts with the respective interest beneficially owned by such
  participants.  The accounts to be credited were designated by the underwriters
  on the offering of the Senior Notes.  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 Note (or portion thereof) is 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 Note 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 Note (or portion thereof).  For any
  redemptions of the Global Note 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

                                       50
<PAGE>
 
  basis, by lot 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.  See "--General."

  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 Receipt 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 (including 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 25%) 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 (INCLUDING 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
  Senior 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.

                                       51

  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.

  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.

  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.

                                       52
<PAGE>
 
     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.

  OBLIGATIONS OF DEPOSITARY AND CUSTODIAN

     Except with respect to the payment of any amount received by it in respect
  of the Global Note, neither the Depositary nor the Custodian will assume any
  obligation or be subject to any liability under the Depositary Agreement,
  other than to use good faith and reasonable care in the performance of its
  respective duties under the Depositary Agreement.

                           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.

                                       53
<PAGE>
 
  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.

  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 NYSE 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

                                       54

<PAGE>
 
        (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 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 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 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,

                                       55
<PAGE>
 
     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, 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 is made
   or accounted for it, 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 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
  ordinarly 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

                                       56
<PAGE>
 
  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 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
  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 the
  transfer of 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.

     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.

                                       57
<PAGE>
 
     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 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 and
  will be long-term capital gain or loss if at the time of such sale,
  redemption, retirement or other disposition the Senior Notes have been held by
  the U.S. Holder for more than one year. 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 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.

                                       58

     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.

     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.

                              PLAN OF DISTRIBUTION

     This Prospectus has been prepared for use by DLJSC in connection with
  offers and sales of the Senior 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 has advised
  the Company that it currently intends to make a market in the Senior Notes but
  it is not obligated to do so 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 Senior Notes.

     DLJSC has provided financial or other advisory services to the Company in
  the past and may do so in the future.  In addition, DLJSC acquired equity
  securities of the Company in connection with the Acquisition. See "Security
  Ownership of Certain Beneficial Owners and Management" and "Certain
  Relationships and Related Transactions--Transactions with the Underwriters."

  ITEM 15.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

       Article 28 of the Bermuda Holdings Bye-Laws provides:

       "(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.

       (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 favour, 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
  offence for which he cannot by law be indemnified he shall reimburse the
  Company the funds advanced."

       Section 98 of the Companies Act 1981 of Bermuda provides:

       (1) Subject to subsection (2), a company may in its bye-laws or in
  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

                                      II-1

<PAGE>
 
  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 wilful negligence, wilful
  default, fraud or dishonesty of which he may be guilty in relation to the
  company shall be void.  Provided that-

       (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 in which judgment is given in his favour 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 that a company
  may purchase and maintain insurance for the benefit of any officer of the
  company against any liability incurred by him in his capacity as an officer of
  the company with respect to a violation of his duty to exercise the care,
  diligence and skill that a reasonably prudent person would exercise in
  comparable circumstances 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.

       The Underwriting Agreement filed as Exhibit 1 hereto provides for
  indemnification by the Underwriters, under certain circumstances, of Company
  and its officers and directors.

       As of December 31, 1996, the Company has 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.

    THE ISSUER

       Article 17 of the Issuer's Memorandum and Articles of Association
  provides that subject to the Companies Act 1985 and every other statute,
  statutory instrument, regulation or order thereunder:

       "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

       (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."

     Section 310 of the Companies Act 1985 provides:

        "(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

                                      II-2
<PAGE>
 
     (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.

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

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

          (a) from purchasing and maintaining for any such officer or auditor
        insurance against any 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) 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."

       The Underwriting Agreement filed as Exhibit 1 hereto provides for
  indemnification by the Underwriters, under certain circumstances, of the
  Issuer and its directors and officers.

       As of December 31, 1996, the Issuer has purchased 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 Conmpany and further excess cover of
  (Pounds)5 million provided by ACE Insurance Company.

  ITEM 17.  UNDERTAKINGS

       The Issuer and Bermuda Holdings hereby undertake:

       (1) That for purposes of determining any liability under the Securities
  Act of 1933, each filing of Bermuda Holdings' annual report pursuant to
  section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and,
  where applicable, each filing of an employee benefit plan's annual report
  pursuant to section 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 shall be deemed to be the initial bona
  fide offering thereof;

       (2) That insofar as indemnification for liabilities arising under the
  Securities Act may be permitted to directors, officers and controlling persons
  of the registrants, pursuant to the provisions described in Item 14 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 and is, therefore, unenforceable.
  In the event that a claim for indemnification against such liabilities (other
  than the payment by the registrants of expenses incurred or paid by a
  director, officer or controlling person of the registrants in the successful
  defense of any action, suit or proceeding) is asserted by any such director,
  officer or controlling person in connection with the securities being
  registered, the registrants will, unless in the opinion of its counsel the
  matter has been settled by controlling precedent, submit to a court of
  appropriate jurisdiction the question of whether or not such indemnification
  is against public as expressed in the Securities Act and will be governed by
  the final adjudication of such issue.

       (3) That for the purposes of determining any liability under the
  Securities Act, the information omitted from the form of prospectus filed as
  part of this registration statement in reliance upon Rule 430A and contained
  in form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.

       (4) That for the purpose of determining any liability under the
  Securities Act, each post-effective amendment that contains a form of
  prospectus 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.

       The Depositary hereby undertakes to furnish promptly the following
  information to the Commission semiannually, beginning on or before six months
  after the effective date of the registration statement:

       (1) The following information in substantially the tabular form

  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.

       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.

Dear Sirs

TERRA NOVA INSURANCE (UK) HOLDINGS PLC ("UK HOLDINGS OR THE COMPANY") 
POST-EFFECTIVE AMENDMENT NO. 2 TO FORMS F-1 AND S-1 - REGISTRATION STATEMENT

You have requested our opinion as to certain United Kingdom taxation matters in 
connection with the Registration Statement referred to above which is to be 
filed by the Company with the Securities and Exchange Commission pursuant to the
Securities Act of 1933 of the United States of America, as amended, relating to 
10 3/4% Senior Notes due 2005 issued by the Company.

Subject to the following assumptions and qualifications, we are of the opinion 
that the description of the United Kingdom taxation treatment of US holders of 
the Senior Notes as set out in said Prospectus under the heading "Certain Tax 
Considerations - Taxation of US Holders of the Senior Notes - United Kingdom", 
as that description is qualified in the statements under the heading "Certain 
Tax Considerations - Certain UK, US and Bermuda Tax Considerations", are correct
summaries of the position under current UK taxation law and practice as at the 
date of this Opinion.

In giving this Opinion, we have relied upon the representations and warranties 
as to factual matters made in or pursuant to the  Registration Statement.  We
have not undertaken independent investigation of any factual matter made in or 
pursuant to the Registration Statement or otherwise.

This Opinion is addressed to you solely for your benefit and may not be relied 
upon by anyone but you without our prior written consent.  We hereby consent to 
the filing of this Opinion as an exhibit to the Registration Statement and to 
the reference made to us under the caption "Enforceability of Civil 
Liabilities", "Risk Factors - Enforcement of Judgments" and "Certain Tax 
Considerations" in the Prospectus forming part of the Registration Statement.

This Opinion is strictly limited to the matters discussed herein and does not 
extend to and is not to be read as extending by implication to any other matter.
For the avoidance of doubt, this Opinion is given in accordance with, and is 
subject to, United Kingdom law.

Yours faithfully

/s/ Clifford Chance

Senior Notes due 2005 of Terra Nova Insurance (UK) Holdings plc, fully and 
unconditionally guaranteed by the Company.

As such counsel, we have examined originals, or copies certified or otherwise 
identified to our satisfaction, of the Memorandum of Association and Bye-Laws

  Holdings, Ltd.



        In so acting, we have examined and relied upon the representations and 
warranties as to factual matters made in or pursuant to the Post-Effective 
Amendment (including exhibits thereto) and originals, or copies certified or 
otherwise identified to our satisfaction, of such records, documents, 
certificates, representations and other instruments as in our judgment are 
necessary or appropriate to enable us to render the opinion expressed below. We
have not, however, undertaken any independent investigation of any factual 
matter set forth in any of the foregoing.

        Subject to the foregoing and the qualifications and limitations set 
forth herein, we are of the opinion that the principal United States federal 
income tax consequences to U.S. Holders of the acquisition, ownership and 
disposition of the Senior Notes are as set forth under the caption "Certain 
Tax Considerations -- Taxation of U.S. Holders of Senior Notes -- United 
States", subject to the qualifications and assumptions set forth in such 
discussion or under "Certain Tax Considerations -- Certain U.K., U.S. and 
Bermuda Tax Considerations", in the Prospectus forming part of the 
Post-Effective Amendment.

        This opinion is limited to the federal law of the United States and 
administrative rulings of the Internal Revenue Service as in effect on the date 
hereof.  We have no obligation to advise you or any other person of changes in 
law or in the administrative rulings of the Internal Revenue Service that occur
after the date hereof.

        We are delivering this opinion to you, and, without our prior written 
consent, no other persons are entitled to rely on this opinion.  We hereby 
consent to the filing of this opinion as an exhibit to the Post-Effective 
Amendment and to the reference to our firm under the caption "Certain Tax 
Considerations -- Certain U.K., U.S. and Bermuda Tax Considerations" in the 
Prospectus forming a part thereof.  In giving such consent, we do not thereby 
concede that we are within the category of persons whose consent is required 
under Section 7 of the Act or the rules and regulations of the Commission 
thereunder.

                                                Very truly yours,
