     This summary highlights certain information incorporated by reference or
appearing elsewhere in this prospectus supplement or the accompanying
prospectus. As a result, it is not complete and does not contain all of the
information that you should consider before purchasing our common stock. You
should read the following summary in conjunction with the more detailed
information contained or incorporated by reference in this prospectus supplement
and the accompanying prospectus. References to "Chubb" are to The Chubb
Corporation. Unless the context otherwise requires, references to "we," "us" and
"our" refer to The Chubb Corporation and its consolidated subsidiaries.

                             THE CHUBB CORPORATION

     The Chubb Corporation, incorporated in New Jersey in 1967, is a holding
company for a family of property and casualty insurance companies known
informally as the Chubb Group of Insurance Companies. Since 1882, we have
provided property and casualty insurance to businesses and individuals around
the world. According to A.M. Best, we are the 12th largest U.S. property and
casualty insurer based on 2002 net written premiums. Net premiums written means
direct premiums written, plus reinsurance premiums assumed, less reinsurance
premiums ceded.

     At March 31, 2003, we had total assets of $35.5 billion and shareholders'
equity of $7.1 billion, and for the year ended December 31, 2002 we had
consolidated net income of $222.9 million. We employed approximately 13,300
persons worldwide at December 31, 2002.

OUR BUSINESS UNITS

     Our property and casualty operations are divided into three strategic
business units:

     CHUBB COMMERCIAL INSURANCE, OR CCI, offers a full range of commercial
customer insurance products, including coverage for multiple peril, casualty,
workers' compensation and property and marine. CCI is known for writing niche
business, where our expertise can add value for our agents, brokers and
policyholders. CCI had net premiums written of $3.4 billion in 2002,
representing 37% of our total for the year.

     CHUBB SPECIALTY INSURANCE, OR CSI, offers a wide variety of specialized
executive protection and professional liability products for privately and
publicly owned companies, financial institutions, professional firms and
healthcare organizations. CSI also includes our surety and accident businesses,
as well as our reinsurance assumed business produced by Chubb Re. CSI had net
premiums written of $3.3 billion in 2002, representing 37% of our total for the
year.

     CHUBB PERSONAL INSURANCE, OR CPI, offers products for individuals with fine
homes and possessions who require more coverage choices and higher limits than
are available with standard insurance policies. CPI had net premiums written of
$2.3 billion in 2002, representing 26% of our total for the year.

     The following table shows the growth in net premiums written at each of our
strategic business units for 2001, 2002 and the first three months of 2003.

STRATEGY

     We believe that successfully executing the following strategies will permit
us to achieve premium and profitability growth in the property and casualty
insurance market.

     MAINTAIN OUR POWERFUL BRAND AND STRONG COMPETITIVE POSITIONS IN OUR CHOSEN
MARKETS.  We have, and intend to maintain, leading franchises in each of our
strategic markets. CCI is a leading provider of commercial insurance in the
middle market, which we believe offers the most significant immediate growth and
profit opportunities in the property and casualty market as a whole. CSI is a
market leader in the executive protection and financial institutions business.
CPI has a particularly strong position in the high net worth personal insurance
market, where we benefit from our well-established Masterpiece(R) brand name.

     CAPITALIZE ON THE PROPERTY AND CASUALTY PRICING ENVIRONMENT.  In late 1998
we began increasing rates in our commercial segment. Since 2001, the rate
structure within the property and casualty market has improved in each of our
segments. Our clear focus on property and casualty products and our strong
presence across the commercial, personal and specialty segments of the market
have enabled us to capitalize on price trends by improving rates throughout our
business units. We also have taken advantage of the favorable environment by
tightening policy terms and conditions throughout our product lines.

     Improved property and casualty pricing dynamics contributed to our 30%
increase in net premiums written in 2002 compared to 2001, and to our 22%
increase in net premiums written in the first quarter of 2003 over the
comparable period in 2002. Our ability to increase our rates was also
fundamental to our achieving cash flow from operating activities of $2.4 billion
in 2002 compared to $1.0 billion in 2001, and $691 million in the first quarter
of 2003 compared to $415 million for the comparable period in 2002.

     CONTINUE TO IMPROVE UNDERWRITING PERFORMANCE.  Our profitability is
extremely sensitive to our underwriting results. The combined loss and expense
ratio, expressed as a percentage, is the key measure of underwriting
profitability traditionally used in the property and casualty business. We use
the statutory definition of combined loss and expense ratio: the sum of the
ratio of losses to premiums earned, or loss ratio, plus the ratio of statutory
underwriting expenses to premiums written, or expense ratio, after reducing both
premium amounts by dividends to policyholders. When the combined ratio is under
100%, underwriting results are generally considered profitable; when the
combined ratio is over 100%, underwriting results are generally considered
unprofitable.

     We have undertaken a renewed focus on disciplined underwriting risk
evaluation and expense control, which is designed to maximize our underwriting
profitability within the constraints of a competitive industry and the
inherently unpredictable timing of the losses for which we insure. We believe
that this initiative is bearing positive results. Our statutory combined ratio
was 95.3% in the first quarter of 2003, which included 4.1 percentage points of
catastrophe losses. For information concerning the calculation of our
underwriting ratios, see "Calculation of Our Underwriting Ratios."

     SUPPORT PROFITABILITY THROUGH POSITIVE INVESTMENT PERFORMANCE.  In addition
to the effect of underwriting results, an insurer's profitability is driven to a
large degree by its income on invested assets. We have consistently recorded
growth in our investment results. Property and casualty investment income before
income taxes increased by 9% in the first quarter of 2003 over the comparable
period in 2002. This performance reflected an increase in invested assets
stemming from strong cash flow from operating activities over the period, as
well as $1 billion of capital contributions from Chubb to the operating
subsidiaries in late 2002. We maintain a high quality, well diversified
investment portfolio that supports our property and casualty business. At March
31, 2003, 87% of this portfolio consisted of fixed-income securities, 65% of
which were rated AAA or equivalent.

     MAINTAIN A STRONG BALANCE SHEET AND RATINGS TO TAKE ADVANTAGE OF GROWTH
OPPORTUNITIES.  The current property and casualty pricing environment, combined
with our strong competitive position across the

                                       S-2


market, presents us with an attractive opportunity to grow premiums. To take
advantage of this opportunity we strive to maintain a balance sheet that can
support the strain of writing new business.

     We believe the steps we have taken to manage our balance sheet provide us
with both the flexibility we need to pursue premium growth and the financial
strength our policyholders expect. In the fourth quarter of 2002 and the first
quarter of 2003 we raised a total of $1.1 billion in new financing, including
$600 million of equity units and $500 million of notes. At the same time, we
believe we have maintained a prudent degree of financial leverage, with a total
debt-to-capital ratio of 26.9% at March 31, 2003. Our senior unsecured debt is
currently rated A by S&P, A1 by Moody's, aa- by A.M. Best and A+ by Fitch. Our
property and casualty subsidiaries' financial strength is rated AA by S&P, Aa2
by Moody's, A++ by A.M. Best and AA by Fitch. The outlook on each of these
ratings is stable, except for the Fitch rating on our senior unsecured debt,
which was placed on negative outlook in March 2003.

RECENT DEVELOPMENTS

  RESULTS OF OPERATIONS FOR THE FIRST QUARTER OF 2003

     The following discussion should be read in conjunction with "-- Summary
Historical Financial Data" and our Quarterly Report on Form 10-Q for the period
ended March 31, 2003, which is incorporated by reference.

     Our net income was $224.6 million in the first quarter of 2003, an increase
of 13.3% over net income of $198.2 million in the first quarter 2002.

     Net premiums written were $2.7 billion in the first quarter of 2003, an
increase of 22% compared with the first quarter of 2002. U.S. premiums grew 21%
over the comparable period in 2002, and we also achieved substantial premium
growth outside the United States; non-U.S. premiums grew 26% on a reported basis
and 16% in local currency terms. Premium growth in the first quarter was strong
in all segments of our business due primarily to higher rates.

     Our statutory combined ratio for the first quarter of 2003 was 95.3%,
compared to 95.9% for the corresponding period in 2002. Catastrophe losses
during the first quarter of 2003 amounted to $94.9 million, which represented
4.1 percentage points of the statutory combined ratio, compared with $13.3
million, or 0.7 of a percentage point, in the first quarter of 2002. Our
statutory expense ratio decreased to 30.4% for the first quarter of 2003,
compared with 31.5% for the first quarter of 2002. The decrease in the statutory
expense ratio was due primarily to premiums written growing at a substantially
higher rate than overhead expenses. For information concerning the calculation
of our underwriting ratios, see "Calculation of Our Underwriting Ratios."

     The following table shows our results by business unit for the first
quarter of 2003:

     Chubb Commercial Insurance.  CCI had premium growth of 21% in the first
quarter of 2003 over the comparable period in 2002. This premium growth resulted
from continued price increases and an

                                       S-3


increase in our in-force policy count. Premiums from new accounts exceeded
non-renewed business by a 2-to-1 margin.

     CCI's statutory combined ratio in the first quarter of 2003 was 86.5%,
compared to 95.7% in the first quarter of 2002. This improvement was due in
large part to the cumulative effect of price increases, better terms and
conditions and more stringent risk selection in recent years. CCI catastrophe
losses accounted for 3.4 points of the statutory combined ratio in the first
quarter of 2003, compared to 0.1 point in the first quarter of 2002.

     Chubb Specialty Insurance.  CSI had premium growth of 29% in the first
quarter of 2003 over the comparable period in 2002. Growth in executive
protection and the professional liability component of the financial
institutions business was primarily attributable to higher rates. In the
fidelity and standard commercial components of our financial institutions
business, rates continued to increase as well. Growth in our other specialty
business was primarily from Chubb Re; premiums produced by Chubb Re grew 58% in
the first quarter of 2003 over the comparable period in 2002.

     CSI's statutory combined ratio in the first quarter of 2003 was 99.2%,
compared to 95.4% in the first quarter of 2002. Our executive protection
business produced unprofitable underwriting results in the first quarter of
2003, compared with near breakeven results in the first quarter of 2002. Results
in the first quarter of 2003 were affected by the adverse claim environment in
directors and officers liability and errors and omissions liability insurance.
Our financial institutions business produced unprofitable results in the first
quarter of 2003, compared with profitable results in the comparable period of
2002. The fidelity and standard commercial components of the financial
institutions business were highly profitable in the first quarters of 2003 and
2002, while results for the professional liability component were highly
unprofitable in both periods, but more so in the first quarter of 2003. This
deterioration was due to the same adverse claim trends experienced in our
executive protection business. Other specialty results were highly profitable in
the first quarters of both 2003 and 2002.

     Chubb Personal Insurance.  CPI had premium growth of 12% in the first
quarter of 2003 over the comparable period in 2002. Premium growth occurred in
all classes. However, as planned, growth in our in-force policy count continued
to slow.

     CPI's statutory combined ratio in the first quarter of 2003 was 103.6%,
compared to 97.4% in the first quarter of 2002. This deterioration was due to
higher catastrophe losses, which represented 10.9 points of the statutory
combined ratio in the first quarter of 2003, compared to 2.4 points in the first
quarter of 2002.

  RESTRUCTURING INITIATIVES

     We have recently undertaken two initiatives to exit from or restructure
certain of our operations.

     Run-off of CFS financial products business.  In addition to our three
strategic insurance business units, in 2000 we organized Chubb Financial
Solutions, or CFS, to engage in developing and providing risk-financing services
through the capital and insurance markets. We recently completed a review of
CFS's strategic future. In April 2003 we announced our intention to run-off the
financial products portfolio of CFS to pursue the more attractive alternative of
deploying our capital to expand our traditional insurance business. We do not
intend to write any new credit derivative transactions, but might enter into
transactions for hedging and other risk management reasons in the future.

     Restructuring of European operations.  We have begun a profit improvement
initiative with respect to our Continental European operations, including
exiting the personal insurance business, except for the ultra-high net worth
market, and rationalizing our expense structure in the remaining commercial and
specialty operations. Our European operations were profitable in the first
quarter of 2003.

                                       S-4


  NEW SENIOR MANAGEMENT TEAM

     In December 2002, Chubb transitioned to a new leadership team. John D.
Finnegan became our President and Chief Executive Officer and a member of our
board of directors. Prior to taking this position at Chubb, Mr. Finnegan had
been the Chairman and President of General Motors Acceptance Corporation and an
Executive Vice President of General Motors Corporation. In assuming the role of
Chief Executive Officer, Mr. Finnegan replaced our outgoing Chairman and Chief
Executive Officer, Dean R. O'Hare, who retired after a 39-year career with us.

     Also in December 2002, Joel J. Cohen, previously our lead director, became
the Chairman of our board of directors, and the board elevated three veteran
Chubb leaders to the position of Vice Chairman. Thomas F. Motamed became our
Vice Chairman and Chief Operating Officer; John J. Degnan was named Vice
Chairman and Chief Administrative Officer; and Michael O'Reilly became Vice
Chairman, Chief Investment Officer and acting Chief Financial Officer. We are
conducting a search for a new Chief Financial Officer.

  RECENT ANNOUNCEMENTS

     On June 6, 2003, we announced that our preliminary estimate for after-tax
catastrophe losses in the two months ended May 31, 2003 is $49 million. In the
three months ended June 30, 2002, catastrophe losses were $7.0 million
after-tax. We also announced that we expect to record in the second quarter of
2003 an after-tax charge of $17 million as a result of a recent adverse
arbitration decision rendered against an insurance pool in which Chubb was
formerly a 5.5% participant. The decision related to a fire loss that occurred
in 1995 and involved property damage and business interruption.

Common stock to be outstanding
 immediately after the
offering:.....................   185,305,623 shares

Concurrent offering:..........   In addition to these shares of common stock, we
                                 are concurrently offering 16,000,000 Equity

                                 contract pursuant to which the holder will
                                 agree to purchase from us shares of our common
                                 stock on August 16, 2006 and a senior note with
                                 a principal amount of $25 due on August 16,
                                 2008. Neither offering is conditioned on the
                                 other.

Use of proceeds:..............   We estimate that the net proceeds from the sale
                                 of shares of common stock in this offering will
                                 be approximately $     million (approximately
                                 $     million if the underwriters exercise
                                 their option to purchase additional shares in
                                 full) and the net proceeds of the sale of our
                                 Equity Units in the concurrent offering will be
                                 approximately $     million (approximately
                                 $     million if the underwriters exercise
                                 their option to purchase additional shares in
                                 full), in each case after deducting the
                                 underwriting discount and commissions and
                                 estimated offering expenses payable by us.

                                 We expect to use the net proceeds from the
                                 offerings for general corporate purposes,
                                 including capital contributions to our

                     CALCULATION OF OUR UNDERWRITING RATIOS

     The combined loss and expense ratio, expressed as a percentage, is the key
measure of underwriting profitability traditionally used in the property and
casualty business. Chubb evaluates the performance of its insurance businesses
by using the combined loss and expense ratio calculated in accordance with
statutory accounting principles applicable to property and casualty insurance
companies. Using statutory accounting principles, the combined loss and expense
ratio is the sum of the ratio of losses to premiums earned (loss ratio) plus the
ratio of statutory underwriting expenses to premiums written (expense ratio)
after reducing both premium amounts by dividends to policyholders.

     Statutory accounting principles differ in certain respects from generally
accepted accounting principles, or GAAP. Under statutory accounting principles,
all expenses are recognized immediately, not at the time premiums are earned. To
convert underwriting expenses to a GAAP basis, policy acquisition expenses are
deferred and recognized over the period in which the related premiums are
earned. While the combined loss and expense ratio is not defined in GAAP
literature, we believe that, using the most directly comparable GAAP measures,
it would be defined as the sum of the ratio of losses to premiums earned (loss
ratio) plus the ratio of GAAP underwriting expenses, including dividends to
policyholders, to premiums earned (expense ratio).

     The expense ratio calculated using GAAP measures generally will be higher
than the statutory expense ratio. The magnitude of this difference generally
will be greater during periods of high premium growth and lesser during periods
of low premium growth. However, we do not believe that the differences in any
period would affect the analysis of underwriting trends in our insurance
businesses.

     To demonstrate the differences, the following table shows, for the three
months ended March 31, 2003 and 2002, the loss ratio, the expense ratio and the
combined loss and expense ratio calculated on a statutory basis and calculated
using GAAP measures:

                                  RISK FACTORS

     In considering whether to purchase our common stock, you should carefully
consider all of the information that we have included in or incorporated by
reference into this prospectus supplement and the accompanying prospectus. In
particular, you should carefully consider the risk factors described below.

PAYMENT OF OBLIGATIONS UNDER SURETY BONDS COULD ADVERSELY AFFECT OUR RESULTS OF
OPERATIONS.

     The surety business tends to be characterized by infrequent but potentially
high severity losses. Since the end of 2001, we have been reducing our exposure
on an absolute basis and by specific bond type. The majority of our obligations
are intended to be performance-based guarantees. When losses occur, they are
mitigated by the customer's balance sheet, contract proceeds and bankruptcy
recovery.

     Notwithstanding our efforts to manage and reduce our surety exposure, we
continue to have substantial commercial surety exposure for outstanding bonds.
In that regard, we have exposures related to commercial surety bonds issued on
behalf of companies that have experienced deterioration in creditworthiness.
Given the current economic climate and its impact on these and other companies,
there is an increased likelihood that we may experience an increase in filed
claims and may incur high severity losses. Such losses would be recorded if and
when claims are filed and determined to be valid.

     In addition, as a result of disarray in the surety reinsurance market
caused by several years of declining prices and high losses, the availability of
surety reinsurance in the near term has been significantly reduced. As a result,
our future surety results could be more volatile.

     We have in force several gas forward purchase surety bonds. The total
amount of bonds with one principal, Aquila, Inc., is approximately $540 million.
These bonds are uncollateralized. The combined amount of all other gas forward
surety bonds is approximately $235 million. Approximately $125 million of these
bonds are uncollateralized. There is currently no reinsurance in place covering
our obligations under any of these bonds.

     These bonds are similar to some of the bonds that we issued on behalf of
Enron Corp., on which payment was triggered by Enron's bankruptcy in December
2001. Under the gas forward purchase surety bond structure, gas suppliers
entered into long-term gas purchase agreements pursuant to which they agreed to
supply specified quantities of gas to the beneficiaries under our surety bonds.
In exchange for the gas purchase agreement, the beneficiaries under our surety
bonds made an agreed upon advance payment for the gas. Our surety bonds secure
the suppliers' obligation to supply gas. Under the terms of these bonds, our
entire obligation to pay could be triggered if the related supplier failed to
provide gas under its forward purchase contracts or was the subject of a
bankruptcy filing.

     Certain of these suppliers, including Aquila, Inc., have suffered ratings
downgrades. Each of the suppliers continues to perform its obligations under the
related gas forward purchase agreements. If payment under the Aquila surety
bonds were triggered or if payment under all of the other gas forward surety
bonds were triggered, such payments would have a material adverse effect on our
results of operations.

RESULTS OF CHUBB FINANCIAL SOLUTIONS ARE SUBJECT TO VOLATILITY FROM PERIOD TO
PERIOD.

     Since its inception in 2000, CFS's non-insurance operations have been
primarily in the credit derivatives business, principally as a counterparty in
portfolio credit default swap contracts. These contracts generally require CFS
to make payment to a counterparty to the extent cumulative losses on a portfolio
of securities, loans or other debt obligations exceed a specified threshold. The
credit default swaps are carried at estimated fair value in our financial
statements, with changes in fair value reflected in income in the period of the
change. The fair value of our obligations under our credit default swaps is
subject to fluctuations arising from, among other factors, changes in credit
spreads, the financial ratings of referenced asset-backed securities, actual
credit events reducing subordination, credit correlation within a portfolio,
anticipated recovery rates related to potential defaults and changes in interest
rates. The non-insurance business of CFS produced a loss before taxes of $69.8
million for the year ended December 31, 2002 and income before taxes of $14.0
million in the first quarter of 2003, mostly due to mark-to-market adjustments.
Thus, income/loss from CFS is subject to volatility from period to period and
can create volatility in our reported earnings.

                                       S-9


     In April 2003, we announced that we intend to run-off the financial
products portfolio of CFS; nonetheless, we will remain exposed to the potential
income statement effects of CFS until substantially all of the portfolio has
been run-off, which we expect will take 3 to 5 years. We do not intend to write
any new credit derivative transactions but might enter into transactions for
hedging and other risk management reasons in the future.

WE MAY INCUR ADDITIONAL LOSSES IF OUR PROPERTY-LIABILITY LOSS RESERVES ARE
INSUFFICIENT.

     The process of establishing loss reserves is complex and imprecise as it is
subject to variables that are influenced by significant judgmental factors. This
is true because claim settlements to be made in the future will be impacted by
changing rates of inflation and other economic conditions, changing legislative,
judicial and social environments and any changes in our claim handling
procedures.

     Our loss reserves include amounts related to short tail and long tail
classes of business. Short tail classes consist principally of homeowners,
personal valuable articles and commercial property business. For these classes,
the estimation of loss reserves is less complex because claims are generally
reported and settled quickly and the claims relate to tangible property.

     Long tail classes include directors and officers liability and other
executive protection coverages, commercial excess liability and other liability
classes. Most of our loss reserves relate to long tail liability classes of
business. For many liability claims, significant periods of time, ranging up to
several years or more, may elapse between the occurrence of the loss, the
reporting of the loss and the settlement of the claim. The longer the time span
between the incidence of a loss and the settlement of the claim, the more the
ultimate settlement amount can vary. For the long tail liability classes, a
relatively small proportion of net losses in the more recent accident years are
reported claims and an even smaller proportion are paid losses. Therefore, a
relatively large proportion of our net losses for these classes are reserves for
incurred but not reported losses -- claims that have not yet been reported to
us, some of which are not yet known to the insured, and future development on
reported claims. In fact, approximately 60% of our aggregate net loss reserves
at March 31, 2003 were for incurred but not reported losses.

     We use a variety of actuarial methods that analyze experience trends and
other relevant factors to estimate loss reserves. These methods generally
utilize analyses of historical patterns of the development of paid and reported
losses by accident year by class of business. This process relies on the basic
assumption that past experience, adjusted for the effects of current
developments and likely trends, is an appropriate basis for predicting future
outcomes. For certain long tail classes of business where anticipated loss
experience is less predictable because of the small number of claims and/or
erratic claim severity patterns, estimates are based on both expected losses and
actual reported losses. These classes include directors and officers liability,
errors and omissions liability and commercial excess liability, among others.
For these classes, we judgmentally set ultimate losses for each accident year
based on our evaluation of loss trends and the current risk environment. The
expected ultimate losses are adjusted as the accident years mature.

     Judicial decisions and legislative actions continue to broaden liability
and policy definitions and to increase the severity of claim payments. As a
result of this and other societal and economic developments, the uncertainties
inherent in estimating ultimate claim costs on the basis of past experience have
been exacerbated, further complicating the already complex loss reserving
process.

     The uncertainties relating to asbestos and toxic waste claims on insurance
policies written many years ago are exacerbated by inconsistent court decisions
as well as judicial interpretation and legislative actions that in some cases
have tended to broaden coverage beyond the original intent of such policies and
in others have expanded theories of liability. The insurance industry as a whole
is engaged in extensive litigation over these coverage and liability issues and
is thus confronted with a continuing uncertainty in its efforts to quantify
these exposures.

     Given the factors described above, it is not possible to quantify precisely
the ultimate exposure or range of exposures represented by claims and related
litigation. We have established reserves that represent our best estimate of
ultimate claims and claim adjustment expenses at March 31, 2003 based upon facts
currently known and the present state of the law and coverage litigation.
However, given the judicial decisions and legislative actions that have
broadened the scope of coverage and expanded theories of

                                       S-10


liability in the past and the possibilities of similar interpretations in the
future, additional increases in loss reserves may emerge in future periods in an
amount that could be material to our results of operations.

THE EFFECTS OF EMERGING CLAIM AND COVERAGE ISSUES ON OUR BUSINESS ARE UNCERTAIN.

     As industry practices and legal, judicial, social and other environmental
conditions change, unexpected and unintended issues related to claim and
coverage may emerge. These issues may adversely affect our business by either
extending coverage beyond our underwriting intent or by increasing the number or
size of claims. Recent examples of emerging claims and coverage issues include:

     - increases in the number and size of water damage claims, including those
       related to expenses for testing and remediation of mold conditions;

     - the effects of disclosures by and investigations of public companies
       relating to possible accounting irregularities, practices in the energy
       and securities industries and other corporate governance issues, which
       have caused increases in the frequency and severity of claims;

     - changes in interpretation of the named insured provision with respect to
       the uninsured/underinsured motorist coverage in commercial automobile
       policies; and

     - a growing trend of plaintiffs targeting property and casualty insurers in
       purported class action litigation relating to claim-handling and other
       practices.

     The effects of these and other unforeseen emerging claim and coverage
issues are extremely hard to predict and could harm our business.

OUR LOSS RESERVES RELATING TO THE SEPTEMBER 11 TERRORIST ATTACK ARE SUBJECT TO
UNCERTAINTY.

     We estimate that our gross claims and claim expenses from the September 11
attack were about $3.2 billion. Our net claims and claim expenses were estimated
to be $645 million due to various reinsurance agreements. Business interruption
claims from the September 11 attack will take some time to resolve, while
potential liability claims could take years to settle. Thus, our loss reserves
related to the September 11 attack are subject to uncertainty. It is possible
that our estimate of ultimate losses related to the September 11 attack may
change in the future and that the change in estimate could have a material
effect on our results of operations.

CATASTROPHE LOSSES COULD MATERIALLY REDUCE OUR PROFITABILITY.

     As a property-liability insurance holding company, our insurance operations
expose us to claims arising out of catastrophes. We have experienced, and will
in the future experience, catastrophe losses which may materially reduce our
profitability or harm our financial condition. Catastrophes can be caused by
various natural events, including hurricanes, windstorms, earthquakes, hail,
severe winter weather and fires. Catastrophes can also be man-made, such as the
terrorist attack of September 11, 2001. Our estimated net costs incurred as a
result of the terrorist attack of September 11, 2001 totaled $645 million. The
frequency and severity of catastrophes are inherently unpredictable. It is
possible that both the frequency and severity of man-made catastrophic events
will increase.

     The extent of losses from a catastrophe is a function of both the total
amount of insured exposure in the area affected by the event and the severity of
the event. Most catastrophes are restricted to small geographic areas; however,
hurricanes and earthquakes may produce significant damage in larger areas,
especially those that are heavily populated. Claims resulting from natural or
man-made catastrophic events could cause substantial volatility in our financial
results for any fiscal quarter or year and could materially reduce our
profitability or harm our financial condition. Our ability to write new business
could also be affected. We believe that increases in the value and geographic
concentration of insured property and the effects of inflation could increase
the severity of claims from catastrophic events in the future. In addition,
states have from time to time passed legislation that has the effect of limiting
the ability of insurers to manage catastrophe risk, such as legislation
prohibiting insurers from withdrawing from catastrophe-prone areas.

                                       S-11


RECENT MANAGEMENT CHANGES CAUSE UNCERTAINTY.

     Dean R. O'Hare, who had been our Chief Executive Officer for 14 years,
retired as Chairman and Chief Executive Officer on November 30, 2002. John D.
Finnegan, formerly Executive Vice President of General Motors Corporation and
Chairman and President of General Motors Acceptance Corporation, became our
President and Chief Executive Officer and a Director on December 1, 2002.

     In addition, since September 26, 2002, Michael O'Reilly, who has been our
Chief Investment Officer since 1988, has been our acting Chief Financial
Officer.

     During the transition of the Chief Executive Officer position and until our
permanent Chief Financial Officer is identified, there may be uncertainty among
investors, rating agencies and others concerning our future direction and
operating philosophy. This uncertainty may increase the volatility of our market
price, and may adversely affect (or delay favorable actions with respect to) our
credit ratings.

IF OUR REAL ESTATE ASSETS ARE NOT SOLD OR DEVELOPED AS PRESENTLY CONTEMPLATED,
IMPAIRMENT LOSSES MAY BE RECOGNIZED.

     At March 31, 2003, we owned land with a carrying value of $300 million that
we expect will be developed in the future and commercial properties and land
parcels under lease with a carrying value of approximately $175 million.

     The recoverability of the carrying value of our real estate assets is
assessed based on our ability to fully recover costs through a future revenue
stream. The assumptions used reflect future improvement in demand for office
space, an increase in rental rates and the ability and intent to obtain
financing in order to hold and develop such remaining properties and protect our
interests over the long term. If the assets are not sold or developed or if
leased properties do not perform as presently contemplated, it is possible that
impairment losses may be recognized.

WE MAY NOT BE ABLE TO RECOVER ALL OF OUR DEFERRED TAX ASSETS RELATING TO LOSSES
AND FOREIGN TAXES INCURRED BY CHUBB EUROPE.

     At December 31, 2002, our deferred income tax asset related to the expected
future U.S. tax benefit of the losses and foreign taxes incurred by Chubb
Insurance Company of Europe (Chubb Europe) was $140 million. To evaluate the
realization of this deferred tax asset, we must consider whether it is more
likely than not that Chubb Europe will generate sufficient taxable income to
realize the future tax benefit of the deferred tax asset. During the fourth
quarter of 2002, we established a valuation allowance of $40 million for the
portion of the deferred tax asset that we cannot realize for accounting
purposes. Results in Chubb Europe were profitable in the first quarter of 2003.
As a result, this deferred tax asset was reduced to $130 million at March 31,
2003. We did not adjust the valuation allowance in the first quarter of 2003. If
our estimates of future taxable income in Chubb Europe were revised upward or
downward, we would need to adjust the valuation allowance accordingly. Depending
on the amount of any such adjustment, the effect on our results of operations
could be significant.

CYCLICALITY OF THE PROPERTY-LIABILITY INSURANCE INDUSTRY MAY CAUSE FLUCTUATIONS
IN OUR RESULTS.

     The property-liability insurance business, especially the commercial lines
business, historically has been characterized by periods of intense price
competition due to excess underwriting capacity, which has in the past had, and
could in the future have, an adverse effect on our results. Periods of intense
price competition historically have alternated with periods when shortages of
underwriting capacity have permitted attractive premium levels. We expect this
cyclicality to continue. The periods of intense price competition in the cycle
could harm our financial condition, profitability or cash flows.

                                       S-12


     A number of factors, including many that are volatile and unpredictable,
can have a significant impact on cyclical trends in the property-liability
insurance industry and the industry's profitability. These factors include:

     - an apparent trend of courts to grant increasingly larger awards for
       certain damages;

     - catastrophic hurricanes, windstorms, earthquakes and other natural
       disasters, as well as the occurrence of man-made disasters (e.g., the
       September 11, 2001 terrorist attack);

     - availability, price and terms of reinsurance;

     - fluctuations in interest rates;

     - changes in the investment environment that affect market prices of and
       income and returns on investments; and

     - inflationary pressures that may tend to affect the size of losses
       experienced by insurance companies.

     We cannot predict whether or when market conditions will improve, remain
constant or deteriorate. Negative market conditions may impair our ability to
write insurance at rates that we consider appropriate relative to the risk
assumed. If we cannot write insurance at appropriate rates, our ability to
transact business would be significantly adversely affected.

A DOWNGRADE IN OUR RATINGS COULD ADVERSELY IMPACT THE COMPETITIVE POSITIONS OF
OUR OPERATING BUSINESSES.

     In the fourth quarter of 2002, several of the principal credit rating
agencies lowered their ratings on our financial strength and securities and S&P
placed us on negative outlook. Reasons given by S&P and Moody's for these
ratings actions included concerns about possible prospective capital strains due
to a high premium growth rate, current loss experience in certain specialty and
personal lines, pending management changes, volatility of our recent operating
performance, our continued exposure to catastrophe-related losses and Moody's
continuing concern about property/casualty insurers' exposure to asbestos
liabilities.

     On March 24, 2003, S&P lowered our long-term counterparty credit and senior
debt ratings from A+ to A and removed them from CreditWatch. In the same action,
S&P lowered its counterparty credit and financial strength ratings on our
operating insurance companies from AA+ to AA and removed them from CreditWatch.
S&P currently has a stable outlook on these ratings.

     If our credit ratings were downgraded, we could incur higher borrowing
costs. Financial strength ratings can be an important factor in establishing the
competitive position of our insurance subsidiaries. There can be no assurance
that our ratings will continue for any given period of time or that they will
not be changed. Further reductions in our ratings could adversely affect the
competitive positions of our operating businesses.

THE INABILITY OF OUR SUBSIDIARIES TO PAY DIVIDENDS TO US IN SUFFICIENT AMOUNTS
WOULD HARM OUR ABILITY TO MEET OUR OBLIGATIONS AND PAY FUTURE DIVIDENDS.

     We are a holding company and rely primarily on dividends from our
subsidiaries to meet our obligations for payment of interest and principal on
outstanding debt obligations, dividends to shareholders and corporate expenses.
The ability of our insurance subsidiaries to pay dividends to us in the future
will depend on their statutory surplus, on earnings and on regulatory
restrictions. We and our insurance subsidiaries are subject to regulation by
some states as an insurance holding company system. Such regulation generally
provides that transactions between companies within the holding company system
must be fair and equitable. Transfers of assets among affiliated companies,
certain dividend payments from insurance subsidiaries and certain material
transactions between companies within the system may be subject to prior notice
to, or prior approval by, state regulatory authorities. Our insurance
subsidiaries are also subject to licensing and supervision by government
regulatory agencies in the jurisdictions in which they do business. These
regulations may set standards of solvency that must be met and maintained, the
nature of and limitations on investments and the nature of and limitations on
dividends to policyholders and shareholders. These regulations may affect our
subsidiaries' ability to provide us with dividends.

                                       S-13


OUR BUSINESSES ARE HEAVILY REGULATED, AND CHANGES IN REGULATION MAY REDUCE OUR
PROFITABILITY AND LIMIT OUR GROWTH.

     Our insurance subsidiaries are subject to extensive regulation and
supervision in the jurisdictions in which they conduct business. This regulation
is generally designed to protect the interests of policyholders, as opposed to
insurers and their shareholders and other investors, and relates to
authorization for lines of business, capital and surplus requirements,
investment limitations, underwriting limitations, transactions with affiliates,
dividend limitations, changes in control, premium rates and a variety of other
financial and nonfinancial components of an insurance company's business.

     Virtually all states require insurers licensed to do business in that state
to bear a portion of the loss suffered by some insureds as the result of
impaired or insolvent insurance companies. In addition, in various states, our
insurance subsidiaries must participate in mandatory arrangements to provide
various types of insurance coverage to individuals or other entities that
otherwise are unable to purchase that coverage from private insurers. The effect
of these and similar arrangements could reduce our profitability in any given
period or limit our ability to grow our business.

     In recent years, the state insurance regulatory framework has come under
increased federal scrutiny, and some state legislatures have considered or
enacted laws that may alter or increase state authority to regulate insurance
companies and insurance holding companies. Further, the National Association of
Insurance Commissioners, or NAIC, and state insurance regulators are reexamining
existing laws and regulations, specifically focusing on modifications to holding
company regulations, interpretations of existing laws and the development of new
laws. Any proposed or future legislation or NAIC initiatives may be more
restrictive than current regulatory requirements or may result in higher costs.

     In response to the terrorist attack on September 11, 2001, the United
States Congress has enacted legislation designed to ensure, among other things,
the availability of insurance coverage for terrorist acts, including by
requiring insurers to provide such coverage in certain circumstances. The
Terrorism Risk Insurance Act of 2002 (the Terrorism Act) established a program
under which the federal government will share the risk of loss from certain acts
of international terrorism with the insurance industry. However, while the
provisions of the Terrorism Act will serve to mitigate our exposure in the event
of a large-scale terrorist attack, our deductible is substantial, approximately
$350 million in 2003. This legislation and any further governmental intervention
could materially and adversely affect us by, among other things, requiring
coverage for terrorist acts to be offered by insurers, benefiting our
competitors or reducing the demand for our products.

INTENSE COMPETITION FOR OUR PRODUCTS COULD HARM OUR ABILITY TO MAINTAIN OR
INCREASE OUR PROFITABILITY AND PREMIUM VOLUME.

     The property and casualty insurance industry is highly competitive. We
compete not only with other stock companies but also with mutual companies,
other underwriting organizations and alternative risk sharing mechanisms. We
compete for business not only on the basis of price, but also on the basis of
availability of coverage desired by customers and quality of service, including
claim adjustment service. We may have difficulty in continuing to compete
successfully on any of these bases in the future.

     If competition limits our ability to write new business at adequate rates,
our ability to transact business would be materially and adversely affected and
our results of operations would be adversely affected.

OUR STOCK PRICE MAY BE VOLATILE.

     Factors such as quarterly variations in our financial results,
announcements by us or our competitors, developments affecting us and general
market volatility could cause the market price of our common stock to fluctuate
significantly.

                                USE OF PROCEEDS

     We estimate that our net proceeds from the sale of shares of common stock
in this offering, based upon a public offering price of $     per share, after
deducting underwriting discounts and commissions and the estimated expenses of
this offering payable by us, will be $     , or $     if the underwriters
exercise their option in full to purchase additional shares. In addition, we
expect to receive net proceeds of $          from the sale of Equity Units in
our concurrent offering, or $          if the underwriters exercise their option
in full to purchase additional Equity Units.

     We expect to use the aggregate net proceeds from this offering and the
concurrent offering of Equity Units for general corporate purposes, including
capital contributions to our operating subsidiaries to support growth.

SHAREHOLDERS

     As of June 4, 2003, approximately 6,050 holders of record held our common
stock.

DIVIDEND POLICY

     As indicated above, Chubb declared quarterly dividends during each of the
two most recent fiscal years in the amounts shown. The Board of Directors will
review its dividend policy periodically, and the declaration of dividends will
necessarily depend upon Chubb's earnings and financial requirements and other
factors within the discretion of the Board of Directors.

     The operations of our subsidiaries are subject, in varying degrees, to
regulatory rules and restrictions on the payment of dividends. Consequently, our
ability to receive dividends from our subsidiaries may be affected from time to
time as a result of these rules and restrictions. For further information, see
"Risk Factors -- The inability of our subsidiaries to pay dividends to us in
sufficient amounts would harm our ability to meet our obligations and pay future
dividends."

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following is a general discussion of certain United States federal
income tax considerations relating to the purchase, ownership and disposition of
shares of our common stock to holders who hold shares of our common stock as
capital assets. This discussion is based upon the Internal Revenue Code of 1986,
as amended (the "Code"), Treasury regulations (including proposed Treasury
regulations) issued thereunder, Internal Revenue Service ("IRS") rulings and
pronouncements and judicial decisions now in effect, all of which are subject to
change, possibly with retroactive effect.

     This discussion does not address all aspects of United States federal
income taxation that may be relevant to holders in light of their particular
circumstances, such as holders who are subject to special tax treatment (for
example, (1) banks, regulated investment companies, insurance companies, dealers
in securities or currencies or tax-exempt organizations, (2) persons holding
shares of common stock as part of a straddle, hedge, conversion transaction or
other integrated investment or (3) persons whose functional currency is not the
U.S. dollar), some of which may be subject to special rules, nor does it address
alternative minimum taxes, federal estate taxes or state, local or foreign
taxes. PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS WITH
RESPECT TO THE TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF
SHARES OF COMMON STOCK IN LIGHT OF THEIR OWN CIRCUMSTANCES.

U.S. HOLDERS

     This discussion applies only to a holder of a share of common stock that is
(1) an individual citizen or resident of the United States, (2) a corporation,
or other entity taxable as a corporation, created or organized in or under the
laws of the United States or any state thereof or the District of Columbia or
(3) a partnership, estate or trust treated, for United States federal income tax
purposes, as a domestic partnership, estate or trust (referred to as a "U.S.
holder").

     Any dividend on our common stock paid by us out of our current or
accumulated earnings and profits (as determined for United States federal income
tax purposes) will be includible in income by a U.S. holder of common stock when
received. Any such dividend will be eligible for the dividends-received
deduction if received by an otherwise qualifying corporate U.S. holder that
meets the holding period and other requirements for the dividends-received
deduction.

     Recently enacted legislation reduces the effective tax rate on dividends
received by individuals through December 31, 2008. Dividends received by
individuals after December 31, 2008 will not benefit from this reduction in tax
rates.

     Upon a disposition of our common stock, a U.S. holder will recognize
capital gain or loss in an amount equal to the difference between the amount
realized and such U.S. holder's adjusted tax basis in the common stock. Capital
gains of individuals derived in respect of capital assets held for more than one
year are taxed at reduced rates. The deductibility of capital losses is subject
to limitations.

NON-U.S. HOLDERS

     If an investor is not a U.S. holder as defined above (a "non-U.S. holder"),
dividends paid to a non-U.S. holder of common stock generally will be subject to
withholding tax at a 30% rate or a reduced rate specified by an applicable
income tax treaty. In order to obtain a reduced rate of withholding, a non-U.S.
holder will be required to provide an IRS Form W-8BEN certifying its entitlement
to benefits under a treaty. The withholding tax does not apply to dividends paid
to a non-U.S. holder who provides a Form W-8ECI, certifying that the dividends
are effectively connected with the non-U.S. holder's conduct of a trade or
business within the United States. Instead, the effectively connected dividends
will be subject to regular U.S. income tax as if the non-U.S. holder were a U.S.
holder. A non-U.S. corporation receiving effectively connected dividends may
also be subject to an additional "branch profits tax" imposed at a rate of 30%
(or a lower treaty rate).

     In general, United States federal withholding tax will not apply to any
gain or income realized by a non-U.S. holder on the sale, exchange or other
disposition of common stock.

                                       S-19


     A non-U.S. holder generally will not be taxed on gain recognized from the
sale, exchange or other disposition of our common stock unless:

     - the non-U.S. holder is an individual who holds our common stock as a
       capital asset, is present in the United States for 183 days or more
       during the taxable year of disposition and meets certain other conditions
       (though any such person will generally be treated as a resident of the
       United States),

     - the gain is effectively connected with the non-U.S. holder's conduct of a
       trade or business in the United States or, in some instances if an income
       tax treaty applies, is attributable to a permanent establishment
       maintained by the non-U.S. holder in the United States, or

     - we are or have been a "U.S. real property holding corporation" for U.S.
       federal income tax purposes at any time during the shorter of the five
       year period ending on the date of disposition or the period that the
       non-U.S. holder held our common stock.

     We have determined that we are not, and we believe we will not become, a
U.S. real property holding corporation.

     Individual non-U.S. holders who are subject to United States tax because
the holder was present in the United States for 183 days or more during the year
of disposition are taxed on their gains (including gains from sales of our
common stock and net of applicable United States losses from sales or exchanges
of other capital assets incurred during the year) at a flat rate of 30%. Other
non-U.S. holders who may be subject to United States federal income tax on the
disposition of our common stock will be taxed on such disposition in the same
manner in which citizens or residents of the United States would be taxed. In
addition, if any such gain is taxable because we are or were a U.S. real
property holding corporation, the buyer of our common stock will be required to
withhold a tax equal to 10% of the amount realized on the sale.

BACKUP WITHHOLDING TAX AND INFORMATION REPORTING

     Unless a U.S. holder is an exempt recipient, such as a corporation,
payments on common stock and the proceeds received from the sale, exchange or
other disposition of common stock may be subject to information reporting and
may also be subject to United States federal backup withholding tax at the
applicable rate if such U.S. holder fails to supply an accurate taxpayer
identification number or otherwise fails to comply with applicable United States
information reporting or certification requirements. Any amounts so withheld may
be allowed as a credit against the holder's United States federal income tax
liability provided the required information is furnished to the IRS.

     A U.S. holder will also be subject to information reporting with respect to
dividends on common stock and proceeds from the sale or other disposition of
common stock, unless such U.S. holder is a corporation or other exempt recipient
and appropriately establishes that exemption.

     A non-U.S. holder may have to comply with certification procedures to
establish that such holder is not a U.S. person in order to avoid information
reporting and backup withholding tax.

     The underwriting agreement provides that the obligations of the
underwriters to purchase the shares included in this offering are subject to
approval of legal matters by counsel and to other conditions. The underwriters
are obligated to purchase all the shares (other than those covered by the option
to purchase additional shares described below) if they purchase any of the
shares.

     The underwriters propose to offer some of the shares directly to the public
at the public offering price set forth on the cover page of this prospectus
supplement and some of the shares to dealers at the public offering price less a
concession not to exceed $     per share. The underwriters may allow, and the
dealers may reallow, a concession not to exceed $     per share on sales to
other dealers. If all of the shares are not sold at the initial offering price,
the underwriters may change the public offering price and the other selling
terms.

     We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus supplement, to purchase up to 2,025,000 additional
shares at the public offering price less the underwriting discount. To the
extent the option is exercised, each underwriter must purchase a number of
additional shares approximately proportionate to that underwriter's initial
purchase commitment.

     We and our executive officers and directors have agreed that, for a period
of 90 days from the date of this prospectus supplement, we and they will not,
without the prior written consent of the underwriters, dispose of, hedge or file
with the SEC a registration statement under the Securities Act with respect to,
any shares of our common stock or any securities convertible into or
exchangeable for our common stock. The foregoing sentence shall not apply to (A)
the shares in this offering and the equity units to be issued to the
underwriters in our concurrent equity units offering and (B)(i) the exercise of
options outstanding as of the date of this prospectus supplement, (ii)
dispositions of common stock by such executive officers or directors by gift to
members of such directors' or officers' immediate families or to trusts
established for the benefit of members of such directors' or officers' immediate
families (provided that any such recipient agrees in writing as a condition to
receiving such common stock to be bound by the foregoing restrictions), (iii)
dispositions of common stock by such executive officers or directors by bona
fide gift to charitable organizations, (iv) our issuance of stock options and
restricted stock to employees, provided that such

                                       S-21


options are not exercisable, and such restricted stock grants do not vest,
before the expiration of the 90-day period, (v) our issuance and sale of common
stock pursuant to any employee stock option plan, stock ownership plan or
dividend reinvestment plan in effect on the date of this prospectus supplement
and (vi) our issuance of common stock issuable upon the conversion of securities
or the exercise of warrants outstanding on the date of this prospectus
supplement.

     The underwriters in their sole discretion may release any of the securities
subject to these lock-up agreements at any time without notice.

     Each underwriter has represented, warranted and agreed that:

     - it has not offered or sold and, prior to the expiry of a period of six
       months from the closing date, will not offer or sell any shares included
       in this offering to persons in the United Kingdom except to persons whose

     In connection with this offering, the underwriters may purchase and sell
the shares of common stock in the open market. These transactions may include
short sales, syndicate covering transactions and stabilizing transactions. Short
sales involve syndicate sales in excess of the number of shares to be purchased
by the underwriters in this offering, which creates a syndicate short position.
"Covered" short sales are sales made in an amount up to the number of shares
represented by the underwriters' over-allotment option. In determining the
source of shares to close out the covered syndicate short position, the
underwriters will consider, among other things, the price of shares available
for purchase in the open market as compared to the price at which they may
purchase shares through the option to purchase additional shares. Transactions
to close out the covered syndicate short involve either purchases of shares in
the open market after the distribution has been completed or the exercise of the
option to purchase additional shares. The underwriters may also make "naked"
short sales of shares in excess of the option to purchase additional shares. The
underwriters must close out any naked short position by purchasing shares in the
open market. A naked short position is more likely to be created if the
underwriters are concerned that there may be downward pressure on the price of
the shares in the open market after pricing that will

                                       S-22


adversely affect investors who purchase in the offering. Stabilizing
transactions consist of bids for or purchases of shares in the open market while
the offering is in progress.

     The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when the
underwriters repurchase shares originally sold by that syndicate member in order
to cover syndicate short positions or make stabilizing purchases.

     Any of these activities may have the effect of preventing or retarding a
decline in the market price of the shares. They may also cause the price of the
shares to be higher than the price that would otherwise exist in the open market
in the absence of these transactions. The underwriters may conduct these
transactions on the New York Stock Exchange or in the over-the-counter market,
or otherwise. If the underwriters commence any of these transactions, they may
discontinue them at any time.

     We estimate that our portion of the total expenses of this offering will be
approximately $          .

     The underwriters and their affiliates have performed investment banking,
commercial lending and advisory services for us from time to time for which they
have received customary fees and expenses. The underwriters may, from time to
time, engage in transactions with and perform services for us in the ordinary
course of their business.

     A prospectus in electronic format may be made available on the websites
maintained by one or more of the underwriters. The underwriters may agree to
allocate a number of shares of our common stock for sale to their online
brokerage account holders. The underwriters have advised us that they will
allocate shares of our common stock for Internet distributions on the same basis
as other allocations. In addition, shares of our common stock may be sold by the
underwriters to securities dealers who resell shares of our common stock to
online brokerage account holders.

     We have agreed to indemnify the underwriters against some liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make because of any of those
liabilities.

                                 LEGAL MATTERS

     The validity of the shares will be passed upon for Chubb by Debevoise &
Plimpton, New York, New York and for the underwriters by Davis Polk & Wardwell,
New York, New York. Debevoise & Plimpton and Davis Polk & Wardwell will rely as
to all matters of New Jersey law upon the opinion of Drinker Biddle & Reath LLP,
Florham Park, New Jersey, counsel to Chubb.

                            16,000,000 EQUITY UNITS

                                  (CHUBB LOGO)

                               ------------------
    We will issue 16,000,000 purchase contracts to purchase our common stock
(18,400,000 purchase contracts if the underwriters exercise their option to
purchase additional purchase contracts in full) and $400,000,000 aggregate
principal amount of     % senior notes due August 16, 2008 ($460,000,000
aggregate principal amount of     % senior notes due August 16, 2008 if the
underwriters exercise their option to purchase additional     % senior notes due
August 16, 2008 in full). The purchase contracts and senior notes will be issued
together in the form of Equity Units, each of which will represent one purchase
contract and $25 principal amount of senior notes. After issuance, purchase
contracts and senior notes may be separated as described in this prospectus
supplement.

    - Each purchase contract will obligate you to purchase from us, no later
      than August 16, 2006, for a stated amount of $25 in cash, a number of
      shares of our common stock as described in this prospectus supplement.

    - We will also pay you quarterly contract adjustment payments at a rate of
          % per year on the stated amount of $25 per purchase contract, or
      $    per year, as described in this prospectus supplement.

    - The senior notes will initially bear interest at a rate of     % per year,
      payable quarterly. The senior notes will be remarketed as described in
      this prospectus supplement. Following a successful remarketing, the
      interest rate on the senior notes may be reset.

    - All of the Equity Units will be issued as Corporate Units. Unless you
      separate your senior notes from your purchase contracts by substituting
      Treasury securities for your senior notes, your Equity Units will remain
      Corporate Units.

    - If the senior notes are remarketed successfully before the third business
      day immediately preceding August 16, 2006, or if a special event
      redemption described in this prospectus supplement occurs before August
      16, 2006, the senior notes represented by the Corporate Units will be
      replaced by the Treasury portfolio described in this prospectus
      supplement.

    - You can create Treasury Units from Corporate Units by substituting
      Treasury securities for the senior notes or your applicable ownership
      interest in the Treasury portfolio represented by the Corporate Units, and
      you can recreate Corporate Units by substituting senior notes or your
      applicable ownership interest in the Treasury portfolio for the Treasury
      securities represented by the Treasury Units.

    - The senior notes or, if substituted for the senior notes, the Treasury
      securities or your applicable ownership interest in the Treasury
      portfolio, as the case may be, will be pledged to us to secure your
      obligation under the related purchase contract.

    Concurrently with this offering, we are offering, by means of a separate
prospectus supplement, 13,500,000 shares of our common stock (or 15,525,000
shares if the underwriters for that offering exercise their option to purchase
additional shares in full). Neither offering is contingent upon the other.

    We will apply to list the Corporate Units on the New York Stock Exchange,
but no assurances can be given that the application for listing will be
approved. Our common stock is traded on the New York Stock Exchange under the
symbol "CB." On June 13, 2003, the reported last sale price of our common stock
on the New York Stock Exchange was $60.00 per share.

     This summary highlights certain information incorporated by reference or
appearing elsewhere in this prospectus supplement or the accompanying
prospectus. As a result, it is not complete and does not contain all of the
information that you should consider before purchasing our Equity Units. You
should read the following summary in conjunction with the more detailed
information contained or incorporated by reference in this prospectus supplement
and the accompanying prospectus. References to "Chubb" are to The Chubb
Corporation. Unless the context otherwise requires, references to "we," "us" and
"our" refer to The Chubb Corporation and its consolidated subsidiaries.

                             THE CHUBB CORPORATION

     The Chubb Corporation, incorporated in New Jersey in 1967, is a holding
company for a family of property and casualty insurance companies known
informally as the Chubb Group of Insurance Companies. Since 1882, we have
provided property and casualty insurance to businesses and individuals around
the world. According to A.M. Best, we are the 12th largest U.S. property and
casualty insurer based on 2002 net written premiums. Net premiums written means
direct premiums written, plus reinsurance premiums assumed, less reinsurance
premiums ceded.

     At March 31, 2003, we had total assets of $35.5 billion and shareholders'
equity of $7.1 billion, and for the year ended December 31, 2002 we had
consolidated net income of $222.9 million. We employed approximately 13,300
persons worldwide at December 31, 2002.

OUR BUSINESS UNITS

     Our property and casualty operations are divided into three strategic
business units:

     CHUBB COMMERCIAL INSURANCE, OR CCI, offers a full range of commercial
customer insurance products, including coverage for multiple peril, casualty,
workers' compensation and property and marine. CCI is known for writing niche
business, where our expertise can add value for our agents, brokers and
policyholders. CCI had net premiums written of $3.4 billion in 2002,
representing 37% of our total for the year.

     CHUBB SPECIALTY INSURANCE, OR CSI, offers a wide variety of specialized
executive protection and professional liability products for privately and
publicly owned companies, financial institutions, professional firms and
healthcare organizations. CSI also includes our surety and accident businesses,
as well as our reinsurance assumed business produced by Chubb Re. CSI had net
premiums written of $3.3 billion in 2002, representing 37% of our total for the
year.

     CHUBB PERSONAL INSURANCE, OR CPI, offers products for individuals with fine
homes and possessions who require more coverage choices and higher limits than
are available with standard insurance policies. CPI had net premiums written of
$2.3 billion in 2002, representing 26% of our total for the year.

     The following table shows the growth in net premiums written at each of our
strategic business units for 2001, 2002 and the first three months of 2003.

STRATEGY

     We believe that successfully executing the following strategies will permit
us to achieve premium and profitability growth in the property and casualty
insurance market.

     MAINTAIN OUR POWERFUL BRAND AND STRONG COMPETITIVE POSITIONS IN OUR CHOSEN
MARKETS.  We have, and intend to maintain, leading franchises in each of our
strategic markets. CCI is a leading provider of commercial insurance in the
middle market, which we believe offers the most significant immediate growth and
profit opportunities in the property and casualty market as a whole. CSI is a
market leader in the executive protection and financial institutions business.
CPI has a particularly strong position in the high net worth personal insurance
market, where we benefit from our well-established Masterpiece(R) brand name.

     CAPITALIZE ON THE PROPERTY AND CASUALTY PRICING ENVIRONMENT.  In late 1998
we began increasing rates in our commercial segment. Since 2001, the rate
structure within the property and casualty market has improved in each of our
segments. Our clear focus on property and casualty products and our strong
presence across the commercial, personal and specialty segments of the market
have enabled us to capitalize on price trends by improving rates throughout our
business units. We also have taken advantage of the favorable environment by
tightening policy terms and conditions throughout our product lines.

     Improved property and casualty pricing dynamics contributed to our 30%
increase in net premiums written in 2002 compared to 2001, and to our 22%
increase in net premiums written in the first quarter of 2003 over the
comparable period in 2002. Our ability to increase our rates was also
fundamental to our achieving cash flow from operating activities of $2.4 billion
in 2002 compared to $1.0 billion in 2001, and $691 million in the first quarter
of 2003 compared to $415 million for the comparable period in 2002.

     CONTINUE TO IMPROVE UNDERWRITING PERFORMANCE.  Our profitability is
extremely sensitive to our underwriting results. The combined loss and expense
ratio, expressed as a percentage, is the key measure of underwriting
profitability traditionally used in the property and casualty business. We use
the statutory definition of combined loss and expense ratio: the sum of the
ratio of losses to premiums earned, or loss ratio, plus the ratio of statutory
underwriting expenses to premiums written, or expense ratio, after reducing both
premium amounts by dividends to policyholders. When the combined ratio is under
100%, underwriting results are generally considered profitable; when the
combined ratio is over 100%, underwriting results are generally considered
unprofitable.

     We have undertaken a renewed focus on disciplined underwriting risk
evaluation and expense control, which is designed to maximize our underwriting
profitability within the constraints of a competitive industry and the
inherently unpredictable timing of the losses for which we insure. We believe
that this initiative is bearing positive results. Our statutory combined ratio
was 95.3% in the first quarter of 2003, which included 4.1 percentage points of
catastrophe losses. For information concerning the calculation of our
underwriting ratios, see "Calculation of Our Underwriting Ratios."

     SUPPORT PROFITABILITY THROUGH POSITIVE INVESTMENT PERFORMANCE.  In addition
to the effect of underwriting results, an insurer's profitability is driven to a
large degree by its income on invested assets. We have consistently recorded
growth in our investment results. Property and casualty investment income before
income taxes increased by 9% in the first quarter of 2003 over the comparable
period in 2002. This performance reflected an increase in invested assets
stemming from strong cash flow from operating activities over the period, as
well as $1 billion of capital contributions from Chubb to the operating
subsidiaries in late 2002. We maintain a high quality, well diversified
investment portfolio that supports our property and casualty business. At March
31, 2003, 87% of this portfolio consisted of fixed-income securities, 65% of
which were rated AAA or equivalent.

     MAINTAIN A STRONG BALANCE SHEET AND RATINGS TO TAKE ADVANTAGE OF GROWTH
OPPORTUNITIES.  The current property and casualty pricing environment, combined
with our strong competitive position across the

                                       S-2


market, presents us with an attractive opportunity to grow premiums. To take
advantage of this opportunity we strive to maintain a balance sheet that can
support the strain of writing new business.

     We believe the steps we have taken to manage our balance sheet provide us
with both the flexibility we need to pursue premium growth and the financial
strength our policyholders expect. In the fourth quarter of 2002 and the first
quarter of 2003 we raised a total of $1.1 billion in new financing, including
$600 million of equity units and $500 million of notes. At the same time, we
believe we have maintained a prudent degree of financial leverage, with a total
debt-to-capital ratio of 26.9% at March 31, 2003. Our senior unsecured debt is
currently rated A by S&P, A1 by Moody's, aa- by A.M. Best and A+ by Fitch. Our
property and casualty subsidiaries' financial strength is rated AA by S&P, Aa2
by Moody's, A++ by A.M. Best and AA by Fitch. The outlook on each of these
ratings is stable, except for the Fitch rating on our senior unsecured debt,
which was placed on negative outlook in March 2003.

RECENT DEVELOPMENTS

  RESULTS OF OPERATIONS FOR THE FIRST QUARTER OF 2003

     The following discussion should be read in conjunction with "-- Summary
Historical Financial Data" and our Quarterly Report on Form 10-Q for the period
ended March 31, 2003, which is incorporated by reference.

     Our net income was $224.6 million in the first quarter of 2003, an increase
of 13.3% over net income of $198.2 million in the first quarter 2002.

     Net premiums written were $2.7 billion in the first quarter of 2003, an
increase of 22% compared with the first quarter of 2002. U.S. premiums grew 21%
over the comparable period in 2002, and we also achieved substantial premium
growth outside the United States; non-U.S. premiums grew 26% on a reported basis
and 16% in local currency terms. Premium growth in the first quarter was strong
in all segments of our business due primarily to higher rates.

     Our statutory combined ratio for the first quarter of 2003 was 95.3%,
compared to 95.9% for the corresponding period in 2002. Catastrophe losses
during the first quarter of 2003 amounted to $94.9 million, which represented
4.1 percentage points of the statutory combined ratio, compared with $13.3
million, or 0.7 of a percentage point, in the first quarter of 2002. Our
statutory expense ratio decreased to 30.4% for the first quarter of 2003,
compared with 31.5% for the first quarter of 2002. The decrease in the statutory
expense ratio was due primarily to premiums written growing at a substantially
higher rate than overhead expenses. For information concerning the calculation
of our underwriting ratios, see "Calculation of Our Underwriting Ratios."

     The following table shows our results by business unit for the first
quarter of 2003:

     Chubb Commercial Insurance.  CCI had premium growth of 21% in the first
quarter of 2003 over the comparable period in 2002. This premium growth resulted
from continued price increases and an

                                       S-3


increase in our in-force policy count. Premiums from new accounts exceeded
non-renewed business by a 2-to-1 margin.

     CCI's statutory combined ratio in the first quarter of 2003 was 86.5%,
compared to 95.7% in the first quarter of 2002. This improvement was due in
large part to the cumulative effect of price increases, better terms and
conditions and more stringent risk selection in recent years. CCI catastrophe
losses accounted for 3.4 points of the statutory combined ratio in the first
quarter of 2003, compared to 0.1 point in the first quarter of 2002.

     Chubb Specialty Insurance.  CSI had premium growth of 29% in the first
quarter of 2003 over the comparable period in 2002. Growth in executive
protection and the professional liability component of the financial
institutions business was primarily attributable to higher rates. In the
fidelity and standard commercial components of our financial institutions
business, rates continued to increase as well. Growth in our other specialty
business was primarily from Chubb Re; premiums produced by Chubb Re grew 58% in
the first quarter of 2003 over the comparable period in 2002.

     CSI's statutory combined ratio in the first quarter of 2003 was 99.2%,
compared to 95.4% in the first quarter of 2002. Our executive protection
business produced unprofitable underwriting results in the first quarter of
2003, compared with near breakeven results in the first quarter of 2002. Results
in the first quarter of 2003 were affected by the adverse claim environment in
directors and officers liability and errors and omissions liability insurance.
Our financial institutions business produced unprofitable results in the first
quarter of 2003, compared with profitable results in the comparable period of
2002. The fidelity and standard commercial components of the financial
institutions business were highly profitable in the first quarters of 2003 and
2002, while results for the professional liability component were highly
unprofitable in both periods, but more so in the first quarter of 2003. This
deterioration was due to the same adverse claim trends experienced in our
executive protection business. Other specialty results were highly profitable in
the first quarters of both 2003 and 2002.

     Chubb Personal Insurance.  CPI had premium growth of 12% in the first
quarter of 2003 over the comparable period in 2002. Premium growth occurred in
all classes. However, as planned, growth in our in-force policy count continued
to slow.

     CPI's statutory combined ratio in the first quarter of 2003 was 103.6%,
compared to 97.4% in the first quarter of 2002. This deterioration was due to
higher catastrophe losses, which represented 10.9 points of the statutory
combined ratio in the first quarter of 2003, compared to 2.4 points in the first
quarter of 2002.

  RESTRUCTURING INITIATIVES

     We have recently undertaken two initiatives to exit from or restructure
certain of our operations.

     Run-off of CFS financial products business.  In addition to our three
strategic insurance business units, in 2000 we organized Chubb Financial
Solutions, or CFS, to engage in developing and providing risk-financing services
through the capital and insurance markets. We recently completed a review of
CFS's strategic future. In April 2003 we announced our intention to run-off the
financial products portfolio of CFS to pursue the more attractive alternative of
deploying our capital to expand our traditional insurance business. We do not
intend to write any new credit derivative transactions, but might enter into
transactions for hedging and other risk management reasons in the future.

     Restructuring of European operations.  We have begun a profit improvement
initiative with respect to our continental European operations, including
exiting the personal insurance business, except for the ultra-high net worth
market, and rationalizing our expense structure in the remaining commercial and
specialty operations. Our European operations were profitable in the first
quarter of 2003.

                                       S-4


  NEW SENIOR MANAGEMENT TEAM

     In December 2002, Chubb transitioned to a new leadership team. John D.
Finnegan became our President and Chief Executive Officer and a member of our
board of directors. Prior to taking this position at Chubb, Mr. Finnegan had
been the Chairman and President of General Motors Acceptance Corporation and an
Executive Vice President of General Motors Corporation. In assuming the role of
Chief Executive Officer, Mr. Finnegan replaced our outgoing Chairman and Chief
Executive Officer, Dean R. O'Hare, who retired after a 39-year career with us.

     Also in December 2002, Joel J. Cohen, previously our lead director, became
the Chairman of our board of directors, and the board elevated three veteran
Chubb leaders to the position of Vice Chairman. Thomas F. Motamed became our
Vice Chairman and Chief Operating Officer; John J. Degnan was named Vice
Chairman and Chief Administrative Officer; and Michael O'Reilly became Vice
Chairman, Chief Investment Officer and acting Chief Financial Officer. We are
conducting a search for a new Chief Financial Officer.

  RECENT ANNOUNCEMENTS

     On June 6, 2003, we announced that our preliminary estimate for after-tax
catastrophe losses in the two months ended May 31, 2003 is $49 million. In the
three months ended June 30, 2002, catastrophe losses were $7.0 million
after-tax. We also announced that we expect to record in the second quarter of
2003 an after-tax charge of $17 million as a result of a recent adverse
arbitration decision rendered against an insurance pool in which Chubb was
formerly a 5.5% participant. The decision related to a fire loss that occurred
in 1995 and involved property damage and business interruption.

(1) Net income has been reduced by aggregate net losses of $700.0 million
    ($455.0 million after-tax or $2.63 per share) recognized in the third and
    fourth quarters related to asbestos and toxic waste claims. Net income has
    also been reduced by a tax valuation allowance of $40.0 million ($0.23 per
    share) from not being able to recognize, for accounting purposes, certain
    U.S. tax benefits related to European losses. Net income has been increased
    by a reduction in net surety bond losses of $88.0 million ($57.2 million
    after-tax or $0.33 per share) resulting from the settlement of litigation
    related to Enron Corp.

(2) Net income has been reduced by net costs of $645.0 million ($420.0 million
    after-tax or $2.39 per share) related to the September 11 attack and by net
    surety bond losses of $220.0 million ($143.0 million after-tax or $0.81 per
    share) arising from the bankruptcy of Enron Corp.

(3) Net income has been reduced by a restructuring charge of $40.0 million
    ($26.0 million after-tax or $0.15 per share).

                                  THE OFFERING

WHAT ARE WE OFFERING?

     We are offering 16,000,000 purchase contracts to purchase our common stock
(18,400,000 purchase contracts if the underwriters exercise their option to
purchase additional purchase contracts in full) and $400,000,000 aggregate
principal amount of      % senior notes due August 16, 2008 ($460,000,000
aggregate principal amount of      % senior notes if the underwriters exercise
their option to purchase additional      % senior notes in full). We are issuing
them together as 16,000,000 Corporate Units (18,400,000 Corporate Units if the
underwriters exercise their option to purchase additional Corporate Units in
full). After they are issued, you can separate the senior notes from the
purchase contracts by creating Treasury Units as we describe below under "How
can I create Treasury Units from Corporate Units?" Corporate Units and Treasury
Units are both referred to in this prospectus supplement as Equity Units. All
references in this prospectus supplement to our common stock include the rights
evidenced by such common stock to the extent provided in the Rights Agreement
dated as of March 12, 1999 between Chubb and EquiServe Trust Company, N.A.

WHAT DOES A CORPORATE UNIT REPRESENT?

     Each Corporate Unit has a stated amount of $25 and will represent one
purchase contract and, initially, $25 principal amount of our   % senior notes
due August 16, 2008. You will own the senior note that is represented by a
Corporate Unit, but it will be held by the collateral agent and pledged to us to
secure your obligation under the purchase contract that is also represented by
that Corporate Unit. If the senior notes are successfully remarketed prior to
the third business day preceding August 16, 2006, or if a special event
redemption occurs prior to August 16, 2006, in each case as described in this
prospectus supplement, the applicable ownership interest in the Treasury
portfolio described below under "What is the Treasury Portfolio?" will replace
your senior notes as a component of each Corporate Unit you own and will be held
by the collateral agent and pledged to us to secure your obligations under the
purchase contract. The senior notes will not trade separately from the Corporate
Units unless and until Treasury Units are created by substituting Treasury
securities for senior notes, the purchase contracts are settled early or the
senior notes are remarketed.

WHAT ARE THE TERMS OF THE PURCHASE CONTRACTS?

     Each purchase contract represented by an Equity Unit obligates the holder
of the purchase contract to purchase, and obligates us to sell, on August 16,
2006, which we refer to as the purchase contract settlement date, for a stated
amount of $25 in cash, a number of newly issued shares of our common stock equal
to the "settlement rate." The settlement rate will be calculated, subject to
adjustment under the circumstances set forth in "Description of the Purchase
Contracts -- Anti-Dilution Adjustments," as follows:

     - if the applicable market value of our common stock is greater than
       $       , which we refer to as the threshold appreciation price, the
       settlement rate will be        shares of our common stock per purchase
       contract;

     - if the applicable market value of our common stock is less than or equal
       to the threshold appreciation price but greater than or equal to $     ,
       which we refer to as the reference price, the settlement rate will be a
       number of shares of our common stock per purchase contract equal to $25
       divided by the applicable market value; and

     - if the applicable market value of our common stock is less than the
       reference price, the settlement rate will be          shares of our
       common stock per purchase contract.

     "Applicable market value" means the average of the closing price per share
of our common stock on each of the twenty consecutive trading days ending on the
third trading day immediately preceding the purchase contract settlement date,
subject to adjustment under the circumstances set forth in "Description

                                       S-7


of the Purchase Contracts -- Anti-Dilution Adjustments." The reference price is
expected to be the reported last sale price of our common stock on the New York
Stock Exchange on the date we price the offering of purchase contracts and
senior notes. The threshold appreciation price represents a      % appreciation
over the reference price.

CAN I SETTLE A PURCHASE CONTRACT EARLY?

     You can settle a purchase contract at any time on or prior to the fifth
business day immediately preceding the purchase contract settlement date by
paying $25 cash, in which case we will issue to you          shares of our
common stock pursuant to the purchase contract, subject to anti-dilution
adjustments. This is the minimum number of shares deliverable per purchase
contract on the purchase contract settlement date. As a result, the market price
of our common stock on or before the early settlement date will not affect the
number of shares received upon early settlement. In addition, if we are involved
in a merger in which at least 30% of the consideration for our common stock
consists of cash or cash equivalents, you will have the right to accelerate and
settle the purchase contract early at the settlement rate in effect immediately
prior to the closing of that merger.

     Your early settlement right is subject to the condition that, if required
under the U.S. federal securities laws, we have a registration statement under
the Securities Act of 1933 in effect covering the shares of common stock and
other securities, if any, deliverable upon settlement of a purchase contract. We
have agreed that, if required by U.S. federal securities laws, we will use our
commercially reasonable efforts to have a registration statement in effect
covering those shares of common stock and any other securities to be delivered
in respect of the purchase contracts being settled.

WHAT ARE TREASURY UNITS?

     Treasury Units are units created from Corporate Units. Each Treasury Unit
represents one purchase contract and a 2.5% undivided beneficial interest in a
zero-coupon U.S. Treasury security with a principal amount of $1,000 that
matures on either July 15, 2006 (CUSIP No.           ) or August 15, 2006 (CUSIP
No.           ), both of which we refer to as a Treasury security. You will own
the interest in the Treasury security that is represented by a Treasury Unit,
but it will be held by the collateral agent and pledged to us to secure your
obligation under the purchase contract that is represented by that Treasury
Unit. With respect to the Treasury securities maturing on July 15, 2006, during
the period between July 15, 2006 and August 15, 2006, any references to the
Treasury securities shall mean the cash proceeds paid on the maturity of such
Treasury securities.

HOW CAN I CREATE TREASURY UNITS FROM CORPORATE UNITS?

     Unless the Treasury portfolio has replaced the senior notes as a component
of the Corporate Units, each holder of Corporate Units will have the right, at
any time on or prior to the fifth business day immediately preceding the
purchase contract settlement date, to substitute for the related senior notes
held by the collateral agent Treasury securities in a total principal amount at
maturity equal to the aggregate principal amount of the senior notes for which
substitution is being made. Because Treasury securities are issued in integral
multiples of $1,000, holders of Corporate Units may make this substitution only
in integral multiples of 40 Corporate Units. If the Treasury portfolio has
replaced the senior notes as a component of the Corporate Units, holders of
Corporate Units will have the right, at any time on or prior to the second
business day immediately preceding the purchase contract settlement date, to
substitute Treasury securities for the applicable ownership interest in the
Treasury portfolio as a component of the Corporate Units, but holders of
Corporate Units can only make this substitution in integral multiples of
Corporate Units. Each of these substitutions will create Treasury Units, and the
applicable senior notes or applicable ownership interest in the Treasury
portfolio will be released to the holder and be separately tradable from the
Treasury Units.

                                       S-8


HOW CAN I RECREATE CORPORATE UNITS FROM TREASURY UNITS?

     Unless the Treasury portfolio has replaced the senior notes as a component
of the Corporate Units, each holder of Treasury Units will have the right, at
any time on or prior to the fifth business day immediately preceding the
purchase contract settlement date, to substitute for the related Treasury
securities held by the collateral agent, senior notes having a principal amount
equal to the aggregate principal amount at stated maturity of the Treasury
securities for which substitution is being made. Because Treasury securities are
issued in integral multiples of $1,000, holders of Treasury Units may make these
substitutions only in integral multiples of 40 Treasury Units. If the Treasury
portfolio has replaced the senior notes as a component of the Corporate Units,
holders of Treasury Units will have the right, at any time on or prior to the
second business day immediately preceding the purchase contract settlement date,
to substitute the applicable ownership interest in the Treasury portfolio for
the Treasury securities as a component of the Treasury Units, but holders of
Treasury Units can only make this substitution in integral multiples of
          Treasury Units. Each of these substitutions will recreate Corporate
Units and the applicable Treasury securities will be released to the holder and
be separately tradable from the Corporate Units.

WHAT PAYMENTS AM I ENTITLED TO AS A HOLDER OF CORPORATE UNITS?

     A holder of a Corporate Unit will be entitled to receive quarterly cash
distributions consisting of interest payments calculated at the rate of      %
per year on the $25 senior note represented by that Corporate Unit (or
distributions on the applicable ownership interest in the Treasury portfolio if
the senior notes have been replaced by the Treasury portfolio) and contract
adjustment payments payable by us at the rate of      % per year on the stated
amount of $25 per purchase contract until the earlier of the purchase contract
settlement date and the most recent quarterly payment date on or before any
early settlement of the related purchase contracts.

WHAT PAYMENTS AM I ENTITLED TO AS A HOLDER OF TREASURY UNITS?

     Holders of Treasury Units will be entitled to receive quarterly contract
adjustment payments payable by us at the rate of      % per year on the stated
amount of $25 per purchase contract. In addition, original issue discount will
accrue on each related Treasury security. When a Treasury Unit is created, the
holder of the Treasury Unit will receive the senior note that was represented by
the Corporate Unit used to create the Treasury Unit. As a holder of that senior
note, the Treasury Unit holder will also be entitled to receive the interest
payments on that senior note, as specified below. The Treasury Unit holders
shall also receive the return earned on the investment by the collateral agent
of the cash proceeds paid on the maturity of the Treasury securities.

DOES CHUBB HAVE THE OPTION TO DEFER CURRENT PAYMENTS?

     We do not have the right to defer the payment of interest on the senior
notes. We have the right to defer the payment of contract adjustment payments
until no later than the date on which your purchase contract is settled. Any
deferred contract adjustment payments will accrue additional contract adjustment
payments at a rate of      % per year, compounded quarterly, until paid.

WHAT ARE THE PAYMENT DATES FOR THE EQUITY UNITS?

     The payments described above in respect of the purchase contracts and
senior notes represented by Equity Units will be payable quarterly in arrears on
February 16, May 16, August 16 and November 16 of each year, commencing August
16, 2003.

WHAT IS REMARKETING?

     Except as described below, the senior notes held by Corporate Unit holders
as part of a Corporate Unit will be remarketed on the third business day
immediately preceding May 16, 2006 (the date three months prior to the purchase
contract settlement date), which we refer to as the initial remarketing date.

                                       S-9


The remarketing agent will use its reasonable efforts to obtain a price for the
remarketed senior notes approximately equal to (but not less than) 100.50% of
the purchase price for the Treasury portfolio described below under "What is the
Treasury Portfolio?". To obtain that price, the remarketing agent may increase
or decrease the interest rate on the senior notes, as described below.

     If the remarketing of the senior notes on the initial remarketing date
fails or does not settle for any reason, the senior notes will continue to be
represented by Corporate Units and the remarketing agent will use its reasonable
efforts to remarket the senior notes on the third business day immediately
preceding June 16, 2006, which we call the second remarketing date, and on the
third business day immediately preceding July 16, 2006, which we call the third
remarketing date, in each case at a price approximately equal to (but not less
than) 100.50% of the purchase price of the Treasury portfolio.

     Following a successful remarketing of the senior notes on any of these
remarketing dates, the portion of the proceeds from the remarketing equal to the
Treasury portfolio purchase price will be applied to purchase the Treasury
portfolio. The Corporate Unit holder's applicable ownership interest in the
Treasury portfolio will be substituted for the senior notes as a component of
the Corporate Units and will be held by the collateral agent and pledged to
secure the Corporate Unit holder's obligation under the purchase contracts. On
the purchase contract settlement date, a portion of the proceeds from the
Treasury portfolio equal to the principal amount of the senior notes will
automatically be applied to satisfy the Corporate Unit holder's obligation to
purchase common stock and proceeds from the Treasury portfolio equal to the
interest payment (assuming no reset of the interest rate) that would have been
due on the senior notes on the purchase contract settlement date will be paid to
the holders of the Corporate Units.

     The remarketing agent will deduct, as a remarketing fee, an amount not
exceeding 25 basis points (.25%) of the Treasury portfolio purchase price from
any proceeds of the remarketing of the senior notes in excess of the Treasury
portfolio purchase price. The remarketing agent will then remit any remaining
portion of the proceeds for the benefit of the holders.

     If a successful remarketing of the senior notes has not occurred on or
prior to the third remarketing date, the remarketing agent will use its
reasonable efforts to remarket the senior notes on the third business day
immediately preceding the purchase contract settlement date, which we refer to
as the final remarketing date, at a price of approximately 100.50% of the
principal amount of the senior notes remarketed, but the remarketing on the
final remarketing date will be considered successful if the resulting proceeds
(net of fees and commissions, if any) are at least 100% of the aggregate
principal amount of the senior notes.

     If the remarketing of the senior notes on the final remarketing date is
successful, a portion of the proceeds from this remarketing equal to the
aggregate principal amount of the senior notes sold in the remarketing that are
represented by the Corporate Units will automatically be applied to satisfy in
full each Corporate Unit holder's obligations to purchase common stock under the
related purchase contracts on the purchase contract settlement date. The
remarketing agent will deduct, as a remarketing fee, an amount not exceeding 25
basis points (.25%) of the aggregate principal amount of the remarketed senior
notes from any proceeds of the remarketing in excess of the aggregate principal
amount of the senior notes remarketed. The remarketing agent will then remit any
remaining portion of the proceeds for the benefit of the holders.

WHAT HAPPENS IF THE SENIOR NOTES ARE NOT SUCCESSFULLY REMARKETED?

     If a successful remarketing of the senior notes represented by your
Corporate Units has not occurred on or prior to the final remarketing date, we
will deliver our common stock to you pursuant to the purchase contracts and,
unless you have delivered the stated amount in respect of the purchase contracts
represented by your Corporate Units to us in cash before the final remarketing
date, we will exercise our rights as a secured party with respect to the senior
notes that have been pledged to us through the collateral agent to secure your
obligation under the related purchase contracts, and your obligation under those
purchase contracts will be deemed to be satisfied in full. In addition, holders
of senior notes that remain outstanding will have the right to put their senior
notes to us for $25 per senior note, plus accrued

                                       S-10


and unpaid interest, on September 30, 2006, which we call the exercise date, by
notifying the indenture trustee on or prior to the fifth business day before the
exercise date.

DO I HAVE TO PARTICIPATE IN THE REMARKETING?

     If you hold Corporate Units, you may elect not to participate in any
remarketing and to retain the senior notes represented by your Corporate Units
by (1) creating Treasury Units at any time on or prior to the second business
day prior to any of the remarketing dates or (2) if the first three remarketing
attempts have failed, notifying the purchase contract agent of your intention to
pay cash to satisfy your obligation under the related purchase contracts on or
prior to the fifth business day before the purchase contract settlement date and
delivering the cash payment required under the purchase contracts to the
collateral agent on or prior to the fourth business day before the purchase
contract settlement date. Following a successful remarketing prior to the third
business day immediately preceding the purchase contract settlement date,
holders of Treasury Units can recreate a Corporate Unit, at any time prior to
the second business day immediately preceding the purchase contract settlement
date, as described under "How can I recreate Corporate Units from Treasury
Units?"

WHAT IS THE TREASURY PORTFOLIO?

     If there is a successful remarketing prior to the third business day
preceding the purchase contract settlement date or if a special event redemption
described under "Description of the Senior Notes -- Optional
Redemption -- Special Event" occurs prior to the purchase contract settlement
date, the senior notes will be replaced by the Treasury portfolio. The Treasury
portfolio is a portfolio of U.S. Treasury securities consisting of:

     - U.S. Treasury securities (or principal or interest strips thereof) that
       mature on or prior to August 15, 2006 in an aggregate amount equal to the
       principal amount of the senior notes represented by the Corporate Units;
       and

     - either:

     (1) in the case of a successful remarketing prior to the third business day
preceding the purchase contract settlement date, U.S. Treasury securities (or
principal or interest strips thereof) that mature on or prior to August 15, 2006
in an aggregate amount equal to the aggregate interest payment (assuming no
reset of the interest rate) that would have been due on the purchase contract
settlement date on the principal amount of the senior notes represented by the
Corporate Units; or

     (2) in the case of a special event redemption, U.S. Treasury securities (or
principal or interest strips thereof) that mature on or prior to the business
day immediately preceding each scheduled interest payment after the date of the
special event redemption and on or prior to the purchase contract settlement
date in an aggregate amount at maturity equal to the aggregate interest payment
(assuming no reset of the interest rate) that would have been due on such
interest payment date on the principal amount of the senior notes represented by
the Corporate Units.

IF I AM HOLDING A SENIOR NOTE AS A SEPARATE SECURITY FROM THE CORPORATE UNITS,
CAN I STILL PARTICIPATE IN A REMARKETING OF THE SENIOR NOTES?

     Holders of senior notes that are not represented by the Corporate Units may
elect, in the manner described in this prospectus supplement, to have their
senior notes remarketed by the remarketing agent along with the senior notes
represented by the Corporate Units. See "Description of the Senior Notes --
Optional Remarketing." Such holders may also participate in any remarketing by
recreating Corporate Units from their Treasury Units at any time on or prior to
the second business day immediately prior to any of the remarketing dates.

                                       S-11


BESIDES PARTICIPATING IN A REMARKETING, HOW ELSE CAN I SATISFY MY OBLIGATION
UNDER THE PURCHASE CONTRACTS?

     Holders of Corporate Units or Treasury Units may also satisfy their
obligations, or their obligations will be terminated, under the purchase
contracts as follows:

     - through early settlement as described under "Can I settle a purchase
       contract early?" above;

     - through the automatic application of the proceeds of the Treasury
       securities in the case of the Treasury Units or the Treasury portfolio in
       the case of Corporate Units if the Treasury portfolio has replaced the
       senior notes as a component of the Corporate Units;

     - if the first three remarketing attempts have failed, through cash
       settlement prior to the final remarketing date in the case of holders of
       Corporate Units, by notifying the purchase contract agent on or prior to
       the fifth business day prior to the purchase contract settlement date and
       delivering the cash payment required under the related purchase contracts
       on or prior to the fourth business day immediately prior to the purchase
       contract settlement date;

     - through the foreclosure of the senior notes that are a component of the
       Corporate Units, if no successful remarketing has occurred and none of
       the above events have taken place; or

     - without any further action, upon the termination of the purchase
       contracts as a result of our bankruptcy, insolvency or reorganization.

     If the holder of a Corporate Unit or Treasury Unit settles the related
purchase contract early, or if the holder's purchase contract is terminated as a
result of our bankruptcy, insolvency or reorganization, such holder will have no
right to receive any accrued contract adjustment payments. See "Description of
the Purchase Contracts -- Early Settlement upon Cash Merger."

WHAT INTEREST PAYMENTS WILL I RECEIVE ON THE SENIOR NOTES?

     Interest on the senior notes will be payable quarterly in arrears initially
at the annual rate of      % per annum to, but excluding, the reset effective
date, which will be the third business day following the date on which a
remarketing of the senior notes is successfully completed. Following a reset of
the interest rate, interest will be payable on the senior notes at the reset
rate from and including the reset effective date to, but excluding, August 16,
2008. If there is not a successful remarketing of the senior notes, the interest
rate will not be reset and the senior notes will continue to bear interest at
the initial interest rate.

WHAT ARE THE INTEREST PAYMENT DATES ON THE SENIOR NOTES?

     The interest payment dates on the senior notes are February 16, May 16,
August 16 and November 16 of each year, commencing August 16, 2003 and ending on
the maturity date of the senior notes.

WHEN WILL THE INTEREST RATE ON THE SENIOR NOTES BE RESET AND WHAT IS THE RESET
RATE?

     Unless a special event redemption has occurred, the interest rate on the
senior notes may be reset on the date of a successful remarketing and the reset
rate will become effective three business days thereafter. The reset rate will
be the interest rate determined by the remarketing agent as the rate the senior
notes should bear in order for the senior notes represented by the Corporate
Units to have an approximate aggregate market value on the remarketing date of
approximately (but not less than) 100.50% of the Treasury portfolio purchase
price, in the case of a remarketing prior to the final remarketing date, or
approximately 100.50% of the aggregate principal amount of the senior notes (but
not less than 100% of that amount plus fees and commissions, if any), in the
case of the final remarketing. The interest rate on the senior notes will not be
reset if there is not a successful remarketing. The reset rate may not exceed
the maximum rate, if any, permitted by applicable law.

                                       S-12


WHEN MAY THE SENIOR NOTES BE REDEEMED?

     The senior notes are redeemable at our option, in whole but not in part,
upon the occurrence and continuation of a tax event or an accounting event at
any time prior to the earlier of the date of a successful remarketing and the
purchase contract settlement date, as described in this prospectus supplement
under "Description of the Senior Notes -- Optional Redemption -- Special Event."
Following any such redemption of the senior notes, which we refer to as a
special event redemption, the redemption price for the senior notes that are
represented by Corporate Units will be paid to the collateral agent, which will
purchase the Treasury portfolio and remit any remaining proceeds to the holders.
Thereafter, the applicable ownership interest in the Treasury portfolio will
replace the senior notes as a component of the Corporate Units and will be held
by the collateral agent and pledged to secure your obligations under the related
purchase contracts. Holders of senior notes that are not represented by
Corporate Units will receive the redemption price paid in such special event
redemption.

WHAT IS THE RANKING OF THE SENIOR NOTES?

     The senior notes will rank equally with all of our other unsecured and
unsubordinated obligations. The indenture under which the senior notes will be
issued will not limit our ability to issue or incur other debt or issue
preferred stock. See "Description of Debt Securities" in the accompanying
prospectus.

WHAT ARE THE U.S. FEDERAL INCOME TAX CONSEQUENCES RELATED TO OWNERSHIP OF THE
EQUITY UNITS AND SENIOR NOTES?

     By purchasing Corporate Units in this offering, you will agree for U.S.
Federal income tax purposes to treat each Corporate Unit as a unit consisting of
a senior note and a purchase contract. In addition, you will agree to treat the
senior notes as our indebtedness for all tax purposes, and to treat the purchase
contracts as forward contracts in respect of our common stock for all tax
purposes. You must allocate the purchase price of the Corporate Units between
the senior notes and the purchase contracts in proportion to their respective
fair market values, which will establish your initial tax basis in each of those
securities. We expect to report the fair market value of each senior note as $
and the fair market value of each purchase contract as $    .

     For U.S. federal income tax purposes, we intend to take the position that
the senior notes are contingent payment debt instruments subject to the
"noncontingent bond method" of accruing original issue discount, and, under the
senior notes indenture, you will agree to take that position. As discussed more
fully under "United States Federal Income Tax -- Senior Notes -- Original issue
discount," the effects of this method will be (1) to require you for all accrual
periods through May 16, 2006 (and possibly thereafter) to accrue interest in
excess of distributions actually received by you regardless of your method of
accounting and (2) to result in ordinary rather than capital treatment of any
gain on the sale, exchange or disposition of the Equity Units (to the extent
attributable to the senior notes) or the senior notes themselves, prior to the
earlier of the date the interest rate is reset or the final remarketing date,
with the result that such ordinary income may not be offset against capital
loss, if any, attributable to a purchase contract.

     We intend to report the contract adjustment payments as income to holders,
but you may want to consult your tax advisor concerning possible alternative
characterizations.

     Because there is no statutory, judicial or administrative authority
directly addressing the tax treatment of Equity Units or instruments similar to
Equity Units, you are urged to consult your own tax advisor concerning the tax
consequences of an investment in Equity Units. For additional information, see
"United States Federal Income Tax."

WILL THE EQUITY UNITS BE LISTED ON A STOCK EXCHANGE?

     We will apply to list the Corporate Units on the New York Stock Exchange,
but no assurances can be given that the application for listing will be
approved. Neither the Treasury Units nor the senior notes will initially be
listed; however, in the event that either of those securities is separately
traded to a sufficient extent that applicable exchange listing requirements are
met, we also will attempt to cause those securities to be listed.

                                       S-13


WHAT ARE THE RIGHTS AND PRIVILEGES OF THE HOLDERS OF COMMON STOCK?

     The shares of our common stock that you will be obligated to purchase under
the purchase contracts have one vote per share. For more information, please see
the discussion of our common stock in the accompanying prospectus under the
heading "Description of Capital Stock."

WHAT ARE THE USES OF PROCEEDS FROM THE OFFERING?

     We intend to use the net proceeds from the sale of the Corporate Units for
general corporate purposes, including capital contributions to our subsidiaries.
See "Use of Proceeds" in this prospectus supplement.

                      THE OFFERING -- EXPLANATORY DIAGRAMS

     The following diagrams demonstrate some of the key features of the purchase
contracts, senior notes, Corporate Units and Treasury Units, and the
transformation of Corporate Units into Treasury Units and senior notes.

     The following diagrams assume that the senior notes are successfully
remarketed, the interest rate on the senior notes is reset on the third business
day immediately preceding the date that is three months before the purchase
contract settlement date, the settlement rate is not adjusted and early
settlement does not apply.

PURCHASE CONTRACTS

     Corporate Units and Treasury Units both represent in part a purchase
contract under which the holder agrees to purchase shares of our common stock on
the purchase contract settlement date. In addition, these purchase contracts
include unsecured contract adjustment payments as shown in the diagrams on the
following pages.

(VALUE OF SHARES DELIVERED GRAPH) (NUMBER OF SHARES DILEVERED GRAPH)
---------------

Notes:

(1) The reference price is assumed to be the reported last sale price of our
    common stock on the New York Stock Exchange on the date we price the
    offering of purchase contracts and senior notes.

(2) The threshold appreciation price represents a      % appreciation over the
    reference price.

                                       S-14


(3) The "applicable market value" means the average of the closing price per
    share of our common stock on each of the twenty consecutive trading days
    ending on the third trading day immediately preceding the purchase contract
    settlement date.

(4) If the applicable market value of our common stock is less than the
    reference price of $     , the number of shares of our common stock to be
    delivered to a holder of a purchase contract will be calculated by dividing
    the stated amount of $25 by the reference price.

(5) If the applicable market value of our common stock is less than or equal to
    the threshold appreciation price of $          but greater than or equal to
    the reference price, the settlement rate will be a number of shares of our
    common stock per purchase contract equal to $25 divided by the applicable
    market value.

(6) If the applicable market value of our common stock is greater than the
    threshold appreciation price, the number of shares of our common stock to be
    delivered to a holder of a purchase contract will be calculated by dividing
    the stated amount by the threshold appreciation price.

CORPORATE UNITS

     A Corporate Unit represents two components as described below:


                                 
        PURCHASE CONTRACT                      SENIOR NOTE
        (Owed to Holder)
          Common Stock                      (Owed to Holder)
                +                               Interest
   Contract Adjustment Payment                 % per annum
           % per annum                       paid quarterly
         paid quarterly
                                           (at reset rate from
                                              May 16, 2006)
         (Owed to Chubb)
        $25 at Settlement                   (Owed to Holder)
        (August 16, 2006)                    $25 at Maturity
                                            (August 16, 2008)


     - The holder of a Corporate Unit owns the senior note that is represented
       by the Corporate Unit but will pledge the senior note to us to secure its
       obligation under the related purchase contract.

     - The foregoing analysis assumes that the senior notes are successfully
       remarketed on the third business day immediately preceding the date that
       is three months before the purchase contract settlement date. Following
       such a remarketing of the senior notes, the applicable ownership interest
       in the Treasury portfolio would replace the senior notes as a component
       of the Corporate Units, and holders of the Corporate Units would receive
       a quarterly payment on the purchase contract settlement date at the same
       annual rate as was paid on the senior notes prior to the remarketing.

     - If the Treasury portfolio has replaced the senior notes as a result of a
       special event redemption prior to the purchase contract settlement date,
       the applicable ownership interest in the Treasury portfolio would also
       replace the senior note as a component of the Corporate Unit.

                                       S-15


TREASURY UNITS

     A Treasury Unit represents two components as described below:


                                    
          PURCHASE CONTRACT                      TREASURY SECURITY
          (Owed to Holder)
            Common Stock
                  +
     Contract Adjustment Payment
             % per annum
           paid quarterly
           (Owed to Chubb)                       (Owed to Holder)
          $25 at Settlement                       $25 at Maturity
          (August 16, 2006)                      (July 15, 2006 or
                                                 August 15, 2006)


     - The holder owns the Treasury security that is represented by the Treasury
       Unit but will pledge the Treasury security to us through the collateral
       agent to secure its obligations under the related purchase contract.
       Unless the purchase contract is terminated as a result of our bankruptcy,
       insolvency or reorganization or the holder recreates a Corporate Unit,
       the Treasury security will be used to satisfy the holder's obligation
       under the related purchase contract.

     - Treasury Units can only be created with integral multiples of 40
       Corporate Units.

SENIOR NOTES

     Senior notes have the terms described below:

                                  SENIOR NOTE
                                               (Owed to Holder)
                                                    Interest
                                                 % per annum
                                                 paid quarterly
                                               (at reset rate from
                                                 May 16, 2006)
                                (Owed to Holder)
                                $25 at Maturity
                               (August 16, 2008)

                                       S-16


TRANSFORMING CORPORATE UNITS INTO TREASURY UNITS AND SENIOR NOTES

     - To create a Treasury Unit, a holder separates a Corporate Unit into its
       components -- the purchase contract and the senior note, and then
       combines the purchase contract with a Treasury security that matures on
       either July 15, 2006 or the day immediately preceding the purchase
       contract settlement date. With respect to the Treasury securities
       maturing on July 15, 2006, during the period between July 15, 2006 and
       August 15, 2006, any reference to the Treasury securities shall mean the
       cash proceeds paid on the maturity of such Treasury securities.

     - The Treasury security together with the purchase contract constitutes a
       Treasury Unit. The senior note, which is no longer represented by the
       Corporate Unit, is released to the holder and is tradable as a separate
       security.

     - A holder owns the Treasury security that is represented by the Treasury
       Unit but will pledge the Treasury security to us through the collateral
       agent to secure its obligation under the related purchase contract.

                                  (FLOW CHART)

     - Following the successful remarketing of the senior notes or a special
       event redemption, the applicable ownership interest in the Treasury
       portfolio, rather than the senior note, will be released to the holder
       upon the transformation of a Corporate Unit into a Treasury Unit and will
       be tradable separately.

     - The holder can also transform Treasury Units and senior notes (or,
       following a successful remarketing of the senior notes or a special event
       redemption, the applicable ownership interest in the Treasury portfolio)
       into Corporate Units. Following that transformation, the Treasury
       security, which will no longer be represented by the Treasury Unit, will
       be released to the holder and will be tradable as a separate security.

     - Unless the Treasury portfolio has replaced the senior notes as a
       component of the Corporate Units, the transformation of Corporate Units
       into Treasury Units requires integral multiples of 40 Corporate Units,
       and the transformation of Treasury Units into Corporate Units also
       requires multiples of 40 Treasury Units. If the Treasury portfolio has
       replaced the senior notes as a component of the Corporate Units, the
       transformation of Corporate Units into Treasury Units requires integral
       multiples of   Corporate Units, and the transformation of Treasury Units
       into Corporate Units requires integral multiples of   Treasury Units.

                     CALCULATION OF OUR UNDERWRITING RATIOS

     The combined loss and expense ratio, expressed as a percentage, is the key
measure of underwriting profitability traditionally used in the property and
casualty business. Chubb evaluates the performance of its insurance businesses
by using the combined loss and expense ratio calculated in accordance with
statutory accounting principles applicable to property and casualty insurance
companies. Using statutory accounting principles, the combined loss and expense
ratio is the sum of the ratio of losses to premiums earned (loss ratio) plus the
ratio of statutory underwriting expenses to premiums written (expense ratio)
after reducing both premium amounts by dividends to policyholders.

     Statutory accounting principles differ in certain respects from generally
accepted accounting principles, or GAAP. Under statutory accounting principles,
all expenses are recognized immediately, not at the time premiums are earned. To
convert underwriting expenses to a GAAP basis, policy acquisition expenses are
deferred and recognized over the period in which the related premiums are
earned. While the combined loss and expense ratio is not defined in GAAP
literature, we believe that, using the most directly comparable GAAP measures,
it would be defined as the sum of the ratio of losses to premiums earned (loss
ratio) plus the ratio of GAAP underwriting expenses, including dividends to
policyholders, to premiums earned (expense ratio).

     The expense ratio calculated using GAAP measures generally will be higher
than the statutory expense ratio. The magnitude of this difference generally
will be greater during periods of high premium growth and lesser during periods
of low premium growth. However, we do not believe that the differences in any
period would affect the analysis of underwriting trends in our insurance
businesses.

     To demonstrate the differences, the following table shows, for the three
months ended March 31, 2003 and 2002, the loss ratio, the expense ratio and the
combined loss and expense ratio calculated on a statutory basis and calculated
using GAAP measures:

                                  RISK FACTORS

     In considering whether to purchase the purchase contracts and senior notes,
you should carefully consider all of the information that we have included in or
incorporated by reference into this prospectus supplement and the accompanying
prospectus. In particular, you should carefully consider the risk factors
described below. Because the purchase contracts and senior notes are being
offered together as Corporate Units, you are making an investment decision with
regard to our common stock and our senior notes. You should carefully review the
information in this prospectus supplement and the accompanying prospectus about
both of these securities.

                         RISKS RELATING TO OUR BUSINESS

PAYMENT OF OBLIGATIONS UNDER SURETY BONDS COULD ADVERSELY AFFECT OUR RESULTS OF
OPERATIONS.

     The surety business tends to be characterized by infrequent but potentially
high severity losses. Since the end of 2001, we have been reducing our exposure
on an absolute basis and by specific bond type. The majority of our obligations
are intended to be performance-based guarantees. When losses occur, they are
mitigated by the customer's balance sheet, contract proceeds and bankruptcy
recovery.

     Notwithstanding our efforts to manage and reduce our surety exposure, we
continue to have substantial commercial surety exposure for outstanding bonds.
In that regard, we have exposures related to commercial surety bonds issued on
behalf of companies that have experienced deterioration in creditworthiness.
Given the current economic climate and its impact on these and other companies,
there is an increased likelihood that we may experience an increase in filed
claims and may incur high severity losses. Such losses would be recorded if and
when claims are filed and determined to be valid.

     In addition, as a result of disarray in the surety reinsurance market
caused by several years of declining prices and high losses, the availability of
surety reinsurance in the near term has been significantly reduced. As a result,
our future surety results could be more volatile.

     We have in force several gas forward purchase surety bonds. The total
amount of bonds with one principal, Aquila, Inc., is approximately $540 million.
These bonds are uncollateralized. The combined amount of all other gas forward
surety bonds is approximately $235 million. Approximately $125 million of these
bonds are uncollateralized. There is currently no reinsurance in place covering
our obligations under any of these bonds.

     These bonds are similar to some of the bonds that we issued on behalf of
Enron Corp., on which payment was triggered by Enron's bankruptcy in December
2001. Under the gas forward purchase surety bond structure, gas suppliers
entered into long-term gas purchase agreements pursuant to which they agreed to
supply specified quantities of gas to the beneficiaries under our surety bonds.
In exchange for the gas purchase agreement, the beneficiaries under our surety
bonds made an agreed upon advance payment for the gas. Our surety bonds secure
the suppliers' obligation to supply gas. Under the terms of these bonds, our
entire obligation to pay could be triggered if the related supplier failed to
provide gas under its forward purchase contracts or was the subject of a
bankruptcy filing.

     Certain of these suppliers, including Aquila, Inc., have suffered ratings
downgrades. Each of the suppliers continues to perform its obligations under the
related gas forward purchase agreements. If payment under the Aquila surety
bonds were triggered or if payment under all of the other gas forward surety
bonds were triggered, such payments would have a material adverse effect on our
results of operations.

RESULTS OF CHUBB FINANCIAL SOLUTIONS ARE SUBJECT TO VOLATILITY FROM PERIOD TO
PERIOD.

     Since its inception in 2000, CFS's non-insurance operations have been
primarily in the credit derivatives business, principally as a counterparty in
portfolio credit default swap contracts. These contracts generally require CFS
to make payment to a counterparty to the extent cumulative losses on a portfolio
of securities, loans or other debt obligations exceed a specified threshold. The
credit default swaps are carried

                                       S-19


at estimated fair value in our financial statements, with changes in fair value
reflected in income in the period of the change. The fair value of our
obligations under our credit default swaps is subject to fluctuations arising
from, among other factors, changes in credit spreads, the financial ratings of
referenced asset-backed securities, actual credit events reducing subordination,
credit correlation within a portfolio, anticipated recovery rates related to
potential defaults and changes in interest rates. The non-insurance business of
CFS produced a loss before taxes of $69.8 million for the year ended December
31, 2002 and income before taxes of $14.0 million in the first quarter of 2003,
mostly due to mark-to-market adjustments. Thus, income/loss from CFS is subject
to volatility from period to period and can create volatility in our reported
earnings.

     In April 2003, we announced that we intend to run-off the financial
products portfolio of CFS; nonetheless, we will remain exposed to the potential
income statement effects of CFS until substantially all of the portfolio has
been run-off, which we expect will take 3 to 5 years. We do not intend to write
any new credit derivative transactions but might enter into transactions for
hedging and other risk management reasons in the future.

WE MAY INCUR ADDITIONAL LOSSES IF OUR PROPERTY-LIABILITY LOSS RESERVES ARE
INSUFFICIENT.

     The process of establishing loss reserves is complex and imprecise as it is
subject to variables that are influenced by significant judgmental factors. This
is true because claim settlements to be made in the future will be impacted by
changing rates of inflation and other economic conditions, changing legislative,
judicial and social environments and any changes in our claim handling
procedures.

     Our loss reserves include amounts related to short tail and long tail
classes of business. Short tail classes consist principally of homeowners,
personal valuable articles and commercial property business. For these classes,
the estimation of loss reserves is less complex because claims are generally
reported and settled quickly and the claims relate to tangible property.

     Long tail classes include directors and officers liability and other
executive protection coverages, commercial excess liability and other liability
classes. Most of our loss reserves relate to long tail liability classes of
business. For many liability claims, significant periods of time, ranging up to
several years or more, may elapse between the occurrence of the loss, the
reporting of the loss and the settlement of the claim. The longer the time span
between the incidence of a loss and the settlement of the claim, the more the
ultimate settlement amount can vary. For the long tail liability classes, a
relatively small proportion of net losses in the more recent accident years are
reported claims and an even smaller proportion are paid losses. Therefore, a
relatively large proportion of our net losses for these classes are reserves for
incurred but not reported losses -- claims that have not yet been reported to
us, some of which are not yet known to the insured, and future development on
reported claims. In fact, approximately 60% of our aggregate net loss reserves
at March 31, 2003 were for incurred but not reported losses.

     We use a variety of actuarial methods that analyze experience trends and
other relevant factors to estimate loss reserves. These methods generally
utilize analyses of historical patterns of the development of paid and reported
losses by accident year by class of business. This process relies on the basic
assumption that past experience, adjusted for the effects of current
developments and likely trends, is an appropriate basis for predicting future
outcomes. For certain long tail classes of business where anticipated loss
experience is less predictable because of the small number of claims and/or
erratic claim severity patterns, estimates are based on both expected losses and
actual reported losses. These classes include directors and officers liability,
errors and omissions liability and commercial excess liability, among others.
For these classes, we judgmentally set ultimate losses for each accident year
based on our evaluation of loss trends and the current risk environment. The
expected ultimate losses are adjusted as the accident years mature.

     Judicial decisions and legislative actions continue to broaden liability
and policy definitions and to increase the severity of claim payments. As a
result of this and other societal and economic developments, the uncertainties
inherent in estimating ultimate claim costs on the basis of past experience have
been exacerbated, further complicating the already complex loss reserving
process.

                                       S-20


     The uncertainties relating to asbestos and toxic waste claims on insurance
policies written many years ago are exacerbated by inconsistent court decisions
as well as judicial interpretations and legislative actions that in some cases
have tended to broaden coverage beyond the original intent of such policies and
in others have expanded theories of liability. The insurance industry as a whole
is engaged in extensive litigation over these coverage and liability issues and
is thus confronted with a continuing uncertainty in its efforts to quantify
these exposures.

     Given the factors described above, it is not possible to quantify precisely
the ultimate exposure or range of exposures represented by claims and related
litigation. We have established reserves that represent our best estimate of
ultimate claims and claim adjustment expenses at March 31, 2003 based upon facts
currently known and the present state of the law and coverage litigation.
However, given the judicial decisions and legislative actions that have
broadened the scope of coverage and expanded theories of liability in the past
and the possibilities of similar interpretations in the future, additional
increases in loss reserves may emerge in future periods in an amount that could
be material to our results of operations.

THE EFFECTS OF EMERGING CLAIM AND COVERAGE ISSUES ON OUR BUSINESS ARE UNCERTAIN.

     As industry practices and legal, judicial, social and other environmental
conditions change, unexpected and unintended issues related to claim and
coverage may emerge. These issues may adversely affect our business by either
extending coverage beyond our underwriting intent or by increasing the number or
size of claims. Recent examples of emerging claims and coverage issues include:

     - increases in the number and size of water damage claims, including those
       related to expenses for testing and remediation of mold conditions;

     - the effects of disclosures by and investigations of public companies
       relating to possible accounting irregularities, practices in the energy
       and securities industries and other corporate governance issues, which
       have caused increases in the frequency and severity of claims;

     - changes in interpretation of the named insured provision with respect to
       the uninsured/underinsured motorist coverage in commercial automobile
       policies; and

     - a growing trend of plaintiffs targeting property and casualty insurers in
       purported class action litigation relating to claim-handling and other
       practices.

     The effects of these and other unforeseen emerging claim and coverage
issues are extremely hard to predict and could harm our business.

OUR LOSS RESERVES RELATING TO THE SEPTEMBER 11 TERRORIST ATTACK ARE SUBJECT TO
UNCERTAINTY.

     We estimate that our gross claims and claim expenses from the September 11
attack were about $3.2 billion. Our net claims and claim expenses were estimated
to be $645 million due to various reinsurance agreements. Business interruption
claims from the September 11 attack will take some time to resolve, while
potential liability claims could take years to settle. Thus, our loss reserves
related to the September 11 attack are subject to uncertainty. It is possible
that our estimate of ultimate losses related to the September 11 attack may
change in the future and that the change in estimate could have a material
effect on our results of operations.

CATASTROPHE LOSSES COULD MATERIALLY REDUCE OUR PROFITABILITY.

     As a property-liability insurance holding company, our insurance operations
expose us to claims arising out of catastrophes. We have experienced, and will
in the future experience, catastrophe losses which may materially reduce our
profitability or harm our financial condition. Catastrophes can be caused by
various natural events, including hurricanes, windstorms, earthquakes, hail,
severe winter weather and fires. Catastrophes can also be man-made, such as the
terrorist attack of September 11, 2001. Our estimated net costs incurred as a
result of the terrorist attack of September 11, 2001 totaled $645 million.

                                       S-21


The frequency and severity of catastrophes are inherently unpredictable. It is
possible that both the frequency and severity of man-made catastrophic events
will increase.

     The extent of losses from a catastrophe is a function of both the total
amount of insured exposure in the area affected by the event and the severity of
the event. Most catastrophes are restricted to small geographic areas; however,
hurricanes and earthquakes may produce significant damage in larger areas,
especially those that are heavily populated. Claims resulting from natural or
man-made catastrophic events could cause substantial volatility in our financial
results for any fiscal quarter or year and could materially reduce our
profitability or harm our financial condition. Our ability to write new business
could also be affected. We believe that increases in the value and geographic
concentration of insured property and the effects of inflation could increase
the severity of claims from catastrophic events in the future. In addition,
states have from time to time passed legislation that has the effect of limiting
the ability of insurers to manage catastrophe risk, such as legislation
prohibiting insurers from withdrawing from catastrophe-prone areas.

RECENT MANAGEMENT CHANGES CAUSE UNCERTAINTY.

     Dean R. O'Hare, who had been our Chief Executive Officer for 14 years,
retired as Chairman and Chief Executive Officer on November 30, 2002. John D.
Finnegan, formerly Executive Vice President of General Motors Corporation and
Chairman and President of General Motors Acceptance Corporation, became our
President and Chief Executive Officer and a Director on December 1, 2002.

     In addition, since September 26, 2002, Michael O'Reilly, who has been our
Chief Investment Officer since 1988, has been our acting Chief Financial
Officer.

     During the transition of the Chief Executive Officer position and until our
permanent Chief Financial Officer is identified, there may be uncertainty among
investors, rating agencies and others concerning our future direction and
operating philosophy. This uncertainty may increase the volatility of our market
price, and may adversely affect (or delay favorable actions with respect to) our
credit ratings.

IF OUR REAL ESTATE ASSETS ARE NOT SOLD OR DEVELOPED AS PRESENTLY CONTEMPLATED,
IMPAIRMENT LOSSES MAY BE RECOGNIZED.

     At March 31, 2003, we owned land with a carrying value of $300 million that
we expect will be developed in the future and commercial properties and land
parcels under lease with a carrying value of approximately $175 million.

     The recoverability of the carrying value of our real estate assets is
assessed based on our ability to fully recover costs through a future revenue
stream. The assumptions used reflect future improvement in demand for office
space, an increase in rental rates and the ability and intent to obtain
financing in order to hold and develop such remaining properties and protect our
interests over the long term. If the assets are not sold or developed or if
leased properties do not perform as presently contemplated, it is possible that
impairment losses may be recognized.

WE MAY NOT BE ABLE TO RECOVER ALL OF OUR DEFERRED TAX ASSETS RELATING TO LOSSES
AND FOREIGN TAXES INCURRED BY CHUBB EUROPE.

     At December 31, 2002, our deferred income tax asset related to the expected
future U.S. tax benefit of the losses and foreign taxes incurred by Chubb
Insurance Company of Europe (Chubb Europe) was $140 million. To evaluate the
realization of this deferred tax asset, we must consider whether it is more
likely than not that Chubb Europe will generate sufficient taxable income to
realize the future tax benefit of the deferred tax asset. During the fourth
quarter of 2002, we established a valuation allowance of $40 million for the
portion of the deferred tax asset that we cannot realize for accounting
purposes. Results in Chubb Europe were profitable in the first quarter of 2003.
As a result, this deferred tax asset was reduced to $130 million at March 31,
2003. We did not adjust the valuation allowance in the first quarter of 2003. If
our estimates of future taxable income in Chubb Europe were revised upward or
downward, we

                                       S-22


would need to adjust the valuation allowance accordingly. Depending on the
amount of any such adjustment, the effect on our results of operations could be
significant.

CYCLICALITY OF THE PROPERTY-LIABILITY INSURANCE INDUSTRY MAY CAUSE FLUCTUATIONS
IN OUR RESULTS.

     The property-liability insurance business, especially the commercial lines
business, historically has been characterized by periods of intense price
competition due to excess underwriting capacity, which has in the past had, and
could in the future have, an adverse effect on our results. Periods of intense
price competition historically have alternated with periods when shortages of
underwriting capacity have permitted attractive premium levels. We expect this
cyclicality to continue. The periods of intense price competition in the cycle
could harm our financial condition, profitability or cash flows.

     A number of factors, including many that are volatile and unpredictable,
can have a significant impact on cyclical trends in the property-liability
insurance industry and the industry's profitability. These factors include:

     - an apparent trend of courts to grant increasingly larger awards for
       certain damages;

     - catastrophic hurricanes, windstorms, earthquakes and other natural
       disasters, as well as the occurrence of man-made disasters (e.g., the
       September 11, 2001 terrorist attack);

     - availability, price and terms of reinsurance;

     - fluctuations in interest rates;

     - changes in the investment environment that affect market prices of and
       income and returns on investments; and

     - inflationary pressures that may tend to affect the size of losses
       experienced by insurance companies.

     We cannot predict whether or when market conditions will improve, remain
constant or deteriorate. Negative market conditions may impair our ability to
write insurance at rates that we consider appropriate relative to the risk
assumed. If we cannot write insurance at appropriate rates, our ability to
transact business would be significantly adversely affected.

A DOWNGRADE IN OUR RATINGS COULD ADVERSELY IMPACT THE COMPETITIVE POSITIONS OF
OUR OPERATING BUSINESSES.

     In the fourth quarter of 2002, several of the principal credit rating
agencies lowered their ratings on our financial strength and securities and S&P
placed us on negative outlook. Reasons given by S&P and Moody's for these
ratings actions included concerns about possible prospective capital strains due
to a high premium growth rate, current loss experience in certain specialty and
personal lines, pending management changes, volatility of our recent operating
performance, our continued exposure to catastrophe-related losses and Moody's
continuing concern about property/casualty insurers' exposure to asbestos
liabilities.

     On March 24, 2003, S&P lowered our long-term counterparty credit and senior
debt ratings from A+ to A and removed them from CreditWatch. In the same action,
S&P lowered its counterparty credit and financial strength ratings on our
operating insurance companies from AA+ to AA and removed them from CreditWatch.
S&P currently has a stable outlook on these ratings.

     If our credit ratings were downgraded, we could incur higher borrowing
costs. Financial strength ratings can be an important factor in establishing the
competitive position of our insurance subsidiaries. There can be no assurance
that our ratings will continue for any given period of time or that they will
not be changed. Further reductions in our ratings could adversely affect the
competitive positions of our operating businesses.

                                       S-23


THE INABILITY OF OUR SUBSIDIARIES TO PAY DIVIDENDS TO US IN SUFFICIENT AMOUNTS
WOULD HARM OUR ABILITY TO MEET OUR OBLIGATIONS AND PAY FUTURE DIVIDENDS.

     We are a holding company and rely primarily on dividends from our
subsidiaries to meet our obligations for payment of interest and principal on
outstanding debt obligations, dividends to shareholders and corporate expenses.
The ability of our insurance subsidiaries to pay dividends to us in the future
will depend on their statutory surplus, on earnings and on regulatory
restrictions. We and our insurance subsidiaries are subject to regulation by
some states as an insurance holding company system. Such regulation generally
provides that transactions between companies within the holding company system
must be fair and equitable. Transfers of assets among affiliated companies,
certain dividend payments from insurance subsidiaries and certain material
transactions between companies within the system may be subject to prior notice
to, or prior approval by, state regulatory authorities. Our insurance
subsidiaries are also subject to licensing and supervision by government
regulatory agencies in the jurisdictions in which they do business. These
regulations may set standards of solvency that must be met and maintained, the
nature of and limitations on investments and the nature of and limitations on
dividends to policyholders and shareholders. These regulations may affect our
subsidiaries' ability to provide us with dividends.

OUR BUSINESSES ARE HEAVILY REGULATED, AND CHANGES IN REGULATION MAY REDUCE OUR
PROFITABILITY AND LIMIT OUR GROWTH.

     Our insurance subsidiaries are subject to extensive regulation and
supervision in the jurisdictions in which they conduct business. This regulation
is generally designed to protect the interests of policyholders, as opposed to
insurers and their shareholders and other investors, and relates to
authorization for lines of business, capital and surplus requirements,
investment limitations, underwriting limitations, transactions with affiliates,
dividend limitations, changes in control, premium rates and a variety of other
financial and nonfinancial components of an insurance company's business.

     Virtually all states require insurers licensed to do business in that state
to bear a portion of the loss suffered by some insureds as the result of
impaired or insolvent insurance companies. In addition, in various states, our
insurance subsidiaries must participate in mandatory arrangements to provide
various types of insurance coverage to individuals or other entities that
otherwise are unable to purchase that coverage from private insurers. The effect
of these and similar arrangements could reduce our profitability in any given
period or limit our ability to grow our business.

     In recent years, the state insurance regulatory framework has come under
increased federal scrutiny, and some state legislatures have considered or
enacted laws that may alter or increase state authority to regulate insurance
companies and insurance holding companies. Further, the National Association of
Insurance Commissioners, or NAIC, and state insurance regulators are reexamining
existing laws and regulations, specifically focusing on modifications to holding
company regulations, interpretations of existing laws and the development of new
laws. Any proposed or future legislation or NAIC initiatives may be more
restrictive than current regulatory requirements or may result in higher costs.

     In response to the terrorist attack on September 11, 2001, the United
States Congress has enacted legislation designed to ensure, among other things,
the availability of insurance coverage for terrorist acts, including by
requiring insurers to provide such coverage in certain circumstances. The
Terrorism Risk Insurance Act of 2002 (the Terrorism Act) established a program
under which the federal government will share the risk of loss from certain acts
of international terrorism with the insurance industry. However, while the
provisions of the Terrorism Act will serve to mitigate our exposure in the event
of a large-scale terrorist attack, our deductible is substantial, approximately
$350 million in 2003. This legislation and any further governmental intervention
could materially and adversely affect us by, among other things, requiring
coverage for terrorist acts to be offered by insurers, benefiting our
competitors or reducing the demand for our products.

                                       S-24


INTENSE COMPETITION FOR OUR PRODUCTS COULD HARM OUR ABILITY TO MAINTAIN OR
INCREASE OUR PROFITABILITY AND PREMIUM VOLUME.

     The property and casualty insurance industry is highly competitive. We
compete not only with other stock companies but also with mutual companies,
other underwriting organizations and alternative risk sharing mechanisms. We
compete for business not only on the basis of price, but also on the basis of
availability of coverage desired by customers and quality of service, including
claim adjustment service. We may have difficulty in continuing to compete
successfully on any of these bases in the future.

     If competition limits our ability to write new business at adequate rates,
our ability to transact business would be materially and adversely affected and
our results of operations would be adversely affected.

OUR STOCK PRICE MAY BE VOLATILE.

     Factors such as quarterly variations in our financial results,
announcements by us or our competitors, developments affecting us and general
market volatility could cause the market price of our common stock to fluctuate
significantly.

                       RISKS RELATING TO THE EQUITY UNITS

YOU ASSUME THE RISK THAT THE MARKET VALUE OF OUR COMMON STOCK MAY DECLINE.

     As a holder of Corporate Units or Treasury Units, you will have an
obligation to buy shares of our common stock pursuant to the purchase contract
that is represented by the Corporate Units or Treasury Units. On the purchase
contract settlement date, unless you pay cash to satisfy your obligation under
the purchase contract or the purchase contracts are terminated due to our
bankruptcy, insolvency or reorganization, (i) in the case of Corporate Units,
either (x) the principal of the appropriate applicable ownership interest in the
Treasury portfolio when paid at maturity or (y) either the proceeds derived from
the successful remarketing of the senior notes or, if no successful remarketing
has occurred, the foreclosure of the senior notes, or (ii) in the case of
Treasury Units, the principal of the related Treasury securities when paid at
maturity, will automatically be used to purchase a specified number of shares of
our common stock on your behalf.

     The number of shares of our common stock that you will receive upon the
settlement of a purchase contract is not fixed but instead will depend on the
average of the closing price per share of our common stock on the 20 consecutive
trading days ending on the third trading day immediately preceding the purchase
contract settlement date, which we refer to as the applicable market value.
There can be no assurance that the market value of common stock received by you
on the purchase contract settlement date will be equal to or greater than the
price per share paid by you for our common stock. If the applicable market value
of the common stock is less than $       , the market value of the common stock
issued to you pursuant to each purchase contract on the purchase contract
settlement date (assuming that the market value is the same as the applicable
market value of the common stock) will be less than the price per share paid by
you for the common stock on the purchase contract settlement date. Accordingly,
you assume the risk that the market value of the common stock may decline, and
that the decline could be substantial.

THE OPPORTUNITY FOR EQUITY APPRECIATION PROVIDED BY AN INVESTMENT IN THE EQUITY
UNITS IS LESS THAN THAT PROVIDED BY A DIRECT INVESTMENT IN OUR COMMON STOCK.

     Your opportunity for equity appreciation afforded by investing in the
Equity Units is less than your opportunity for equity appreciation if you
directly invested in our common stock. This opportunity is less because the
market value of the common stock to be received by you pursuant to the purchase
contract on the purchase contract settlement date (assuming that the market
value is the same as the applicable market value of the common stock) will only
exceed the price per share paid by you for our common stock on the purchase
contract settlement date if the applicable market value of the common stock

                                       S-25


exceeds the threshold appreciation price (which represents an appreciation of
     % over $       ). If the applicable market value of our common stock
exceeds the reference price but does not exceed the threshold appreciation
price, you will realize no equity appreciation of the common stock for the
period during which you own the purchase contract. Furthermore, if the
applicable market value of our common stock exceeds the threshold appreciation
price, you would receive on the purchase contract settlement date only
approximately      % of the value of the shares of common stock you could have
purchased with $25 at the reported last sale price of our common stock on the
date of issuance of the Equity Units.

THE TRADING PRICES FOR THE CORPORATE UNITS AND TREASURY UNITS WILL BE DIRECTLY
AFFECTED BY THE TRADING PRICES OF OUR COMMON STOCK.

     The trading prices of Corporate Units and Treasury Units in the secondary
market will be directly affected by the trading prices of our common stock, the
general level of interest rates and our credit quality. It is impossible to
predict whether the price of the common stock or interest rates will rise or
fall. Trading prices of the common stock will be influenced by our operating
results and prospects and by economic, financial and other factors. In addition,
general market conditions, including the level of, and fluctuations in the
trading prices of stocks generally, and sales of substantial amounts of common
stock by us in the market after the offering of the Equity Units, or the
perception that such sales could occur, could affect the price of our common
stock. Fluctuations in interest rates may give rise to arbitrage opportunities
based upon changes in the relative value of the common stock represented by the
purchase contracts and of the other components of the Equity Units. Any such
arbitrage could, in turn, affect the trading prices of the Corporate Units,
Treasury Units, senior notes and our common stock.

IF YOU HOLD CORPORATE UNITS OR TREASURY UNITS, YOU WILL NOT BE ENTITLED TO ANY
RIGHTS WITH RESPECT TO OUR COMMON STOCK, BUT YOU WILL BE SUBJECT TO ALL CHANGES
MADE WITH RESPECT TO OUR COMMON STOCK.

     If you hold Corporate Units or Treasury Units, you will not be entitled to
any rights with respect to our common stock (including, without limitation,
voting rights and rights to receive any dividends or other distributions on the
common stock), but you will be subject to all changes affecting the common
stock. You will only be entitled to rights on the common stock if and when we
deliver shares of common stock in exchange for Corporate Units or Treasury Units
on the purchase contract settlement date, or as a result of early settlement, as
the case may be, and the applicable record date, if any, for the exercise of
rights occurs after that date. For example, in the event that an amendment is
proposed to our articles of incorporation or by-laws requiring stockholder
approval and the record date for determining the stockholders of record entitled
to vote on the amendment occurs prior to delivery of the common stock, you will
not be entitled to vote on the amendment, although you will nevertheless be
subject to any changes in the powers, preferences or special rights of our
common stock.

WE MAY ISSUE ADDITIONAL SHARES OF COMMON STOCK AND THEREBY MATERIALLY AND
ADVERSELY AFFECT THE PRICE OF OUR COMMON STOCK.

     The number of shares of common stock that you are entitled to receive on
the purchase contract settlement date or as a result of early settlement of a
purchase contract, is subject to adjustment for certain events arising from
stock splits and combinations, stock dividends and certain other actions by us
that modify our capital structure. We will not adjust the number of shares of
common stock that you are to receive on the purchase contract settlement date,
or as a result of early settlement of a purchase contract for other events,
including offerings of common stock for cash by us or in connection with
acquisitions. We are not restricted from issuing additional common stock during
the term of the purchase contracts and have no obligation to consider your
interests for any reason. If we issue additional shares of common stock, it may
materially and adversely affect the price of our common stock and, because of
the relationship of the number of shares to be received on the purchase contract
settlement date to the price of the common stock, such other events may
adversely affect the trading price of the Corporate Units or Treasury Units.

                                       S-26


THE SECONDARY MARKET FOR THE CORPORATE UNITS, TREASURY UNITS OR SENIOR NOTES MAY
BE ILLIQUID.

     It is not possible to predict how Corporate Units, Treasury Units or senior
notes will trade in the secondary market or whether the market will be liquid or
illiquid. There is currently no secondary market for our Corporate Units,
Treasury Units or senior notes. We will apply to list the Corporate Units on the
New York Stock Exchange, but no assurances can be given that the application for
listing will be approved. If the Treasury Units or the senior notes are
separately traded to a sufficient extent that applicable exchange listing
requirements are met, we will also try to list the Treasury Units or the senior
notes. There can be no assurance as to the liquidity of any market that may
develop for the Corporate Units, the Treasury Units or the senior notes, your
ability to sell these securities or whether a trading market, if it develops,
will continue. In addition, in the event you were to substitute Treasury
securities for senior notes or senior notes for Treasury securities, thereby
converting your Corporate Units to Treasury Units or your Treasury Units to
Corporate Units, as the case may be, the liquidity of Corporate Units or
Treasury Units could be adversely affected. There can be no assurance that the
Corporate Units, if listed, will not be delisted from the New York Stock
Exchange or that trading in the Corporate Units will not be suspended as a
result of holders electing to create Treasury Units by substituting collateral,
which could cause the number of Corporate Units to fall below the requirement
for listing securities on the New York Stock Exchange.

YOUR RIGHTS TO THE PLEDGED SECURITIES WILL BE SUBJECT TO OUR SECURITY INTEREST.

     Although you will be the beneficial owner of the related senior notes,
Treasury securities or applicable ownership interest in the Treasury portfolio,
as applicable, those securities will be held by the collateral agent and pledged
to secure your obligations under the related purchase contracts. Thus, your
rights to the pledged securities will be subject to our security interest.
Additionally, notwithstanding the automatic termination of the purchase
contracts, in the event that we become the subject of a case under the U.S.
Bankruptcy Code, the delivery of the pledged securities to you may be delayed by
the imposition of the automatic stay under Section 362 of the Bankruptcy Code
and claims arising out of the senior notes, like all other claims in bankruptcy
proceedings, will be subject to the equitable jurisdiction and powers of the
bankruptcy court.

THE SENIOR NOTES MAY BE REDEEMED UPON THE OCCURRENCE OF A SPECIAL EVENT.

     We may redeem the senior notes, on not less than 30 days' nor more than 60
days' prior written notice, in whole but not in part, at any time before the
earlier of the date of a successful remarketing of the senior notes represented
by the Corporate Units and the purchase contract settlement date if a special
event occurs and continues under the circumstances described in this prospectus
supplement. If we exercise this option, we will redeem the senior notes for cash
at the redemption amount plus accrued and unpaid interest, if any, which we
refer to as the redemption price. Unless the senior notes have been successfully
remarketed, if the special event redemption occurs before the purchase contract
settlement date, the redemption price payable to you as a holder of the
Corporate Units will be distributed to the collateral agent, who in turn will
purchase the Treasury portfolio on your behalf, and will remit the remainder of
the redemption price, if any, to you, and the Treasury portfolio will be
substituted for the senior notes as collateral to secure your obligations under
the purchase contracts represented by the Corporate Units. If your senior notes
are not represented by Corporate Units, you will receive redemption payments
directly. There can be no assurance as to the impact on the market prices for
the Corporate Units if the Treasury portfolio is substituted as collateral in
place of any senior notes redeemed. A special event redemption will be a taxable
event to the holders of the senior notes.

THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND
DISPOSITION OF THE EQUITY UNITS ARE UNCLEAR, AND THE SENIOR NOTES ARE SUBJECT TO
CERTAIN UNFAVORABLE TAX RULES.

     No statutory, judicial or administrative authority directly addresses the
treatment of Equity Units or instruments similar to Equity Units for U.S.
federal income tax purposes. As a result, the U.S. federal income tax
consequences of the purchase, ownership and disposition of the Equity Units are
unclear.

                                       S-27


Under the senior notes indenture, we and each holder will agree to treat the
senior notes as contingent payment debt instruments for U.S. federal income tax
purposes. As a result, you will be required, subject to some adjustments, to
include interest in income based on our comparable yield, which is generally the
rate at which we would borrow if we issued non-contingent debt instruments with
terms substantially the same as the senior notes, and which we have determined
to be      %. Additionally, any gain on the disposition of the senior notes
before the interest rate reset (or before the final remarketing date, if
earlier) generally will be treated as ordinary interest income; thus, the
ability to offset that interest income with a loss, if any, on a purchase
contract may be limited. For additional information, see "United States Federal
Income Tax -- Senior Notes -- Original issue discount."

THE PURCHASE CONTRACT AGREEMENT WILL NOT BE QUALIFIED UNDER THE TRUST INDENTURE
ACT AND THE OBLIGATIONS OF THE PURCHASE CONTRACT AGENT ARE LIMITED.

     The purchase contract agreement between us and the purchase contract agent
will not be qualified as an indenture under the Trust Indenture Act of 1939, and
the purchase contract agent will not be required to qualify as a trustee under
the Trust Indenture Act. Thus, you will not have the benefit of the protection
of the Trust Indenture Act with respect to the purchase contract agreement or
the purchase contract agent. The senior notes that are represented by the
Corporate Units will be issued pursuant to an indenture, which will be qualified
under the Trust Indenture Act. Accordingly, if you hold Corporate Units, you
will have the benefit of the protections of the Trust Indenture Act only to the
extent applicable to the senior notes represented by the Corporate Units.

     The protections generally afforded the holder of a security issued under an
indenture that has been qualified under the Trust Indenture Act include:

     - disqualification of the indenture trustee for "conflicting interests," as
       defined under the Trust Indenture Act;

     - provisions preventing a trustee that is also a creditor of the issuer
       from improving its own credit position at the expense of the security
       holders immediately prior to or after a default under such indenture; and

     - the requirement that the indenture trustee deliver reports at least
       annually with respect to certain matters concerning the indenture trustee
       and the securities.

THE TRADING PRICE OF THE SENIOR NOTES MAY NOT FULLY REFLECT THE VALUE OF THEIR
ACCRUED BUT UNPAID INTEREST.

     The senior notes may trade at a price that does not fully reflect the value
of their accrued but unpaid interest. If you dispose of your senior notes
between record dates for interest payments, you will be required to include in
gross income the daily portions of original issue discount through the date of
disposition in income as ordinary income, and to add this amount to your
adjusted tax basis in the senior notes disposed of. To the extent the selling
price is less than your adjusted tax basis, you will recognize a loss.

                              ACCOUNTING TREATMENT

GENERAL

     The proceeds from the sale of the Corporate Units will be allocated between
the purchase contracts and the senior notes based on the fair value of each at
the date of the offering. We expect the fair value of each purchase contract to
be $    .

     We will recognize the present value of the quarterly contract adjustment
payments as a liability with an offsetting reduction in shareholders' equity.
The quarterly contract adjustment payments will be allocated between the
liability recognized at the date of issuance and interest expense based on a
constant rate calculation over the term of the purchase contract.

     The quarterly interest payments on the senior notes will be recognized as
interest expense.

     Fees and expenses incurred in connection with this offering will be
allocated between the senior notes and the purchase contracts. The amount
allocated to the senior notes will be deferred and recognized as interest
expense over the term of the senior notes. The amount allocated to the purchase
contracts will be charged to shareholders' equity.

     When we settle the purchase contracts, we will issue the requisite number
of shares of our common stock, and the amount we receive will be added to
shareholders' equity and allocated between common stock and paid-in surplus.

EARNINGS PER SHARE

     Before the settlement of the purchase contracts, we will consider the
shares to be issued under the purchase contracts in our calculation of diluted
earnings per share using the treasury stock method. Under this method, we will
increase the number of shares of our common stock used in calculating diluted
earnings per share by the excess, if any, of the number of shares we would be
required to issue to settle the purchase contracts over the number of shares
that we could purchase using the proceeds from the settlement of the purchase
contracts. We anticipate that there will be no dilution of our earnings per
share except during the periods when the average price of our common stock is
above $     per share.

OTHER MATTERS

     Both the Financial Accounting Standards Board and its Emerging Issues Task
Force continue to study the accounting for financial instruments and derivative
instruments including instruments such as the purchase contracts. It is possible
that our accounting for the purchase contracts and the senior notes could be
affected by any new accounting rules that might be issued by these groups.

                                       S-31


                                USE OF PROCEEDS

     We estimate that our net proceeds from the sale of purchase contracts and
senior notes in this offering, after deducting underwriting discounts and
commissions and the estimated expenses of this offering payable by us, will be
$          , or $          if the underwriters exercise their option in full to
purchase additional purchase contracts and senior notes. In addition, we expect
to receive net proceeds of $          from our concurrent common stock offering,
or $          if the underwriters exercise their option in full to purchase
additional shares, based upon a public offering price of $          per share.

     We expect to use the aggregate net proceeds from this offering and the
concurrent common stock offering for general corporate purposes, including
capital contributions to our operating subsidiaries to support growth.

(1) Dividend to be paid on July 8, 2003 to shareholders of record on June 20,
    2003.

SHAREHOLDERS

     As of June 4, 2003, approximately 6,050 holders of record held our common

DIVIDEND POLICY

     As indicated above, Chubb declared quarterly dividends during each of the
two most recent fiscal years in the amounts shown. The Board of Directors will
review its dividend policy periodically, and the declaration of dividends will
necessarily depend upon Chubb's earnings and financial requirements and other
factors within the discretion of the Board of Directors.

     The operations of our subsidiaries are subject, in varying degrees, to
regulatory rules and restrictions on the payment of dividends. Consequently, our
ability to receive dividends from our subsidiaries may be affected from time to
time as a result of these rules and restrictions. For further information, see
"Risk Factors -- Risks Relating to Our Business -- The inability of our
subsidiaries to pay dividends to us in sufficient amounts would harm our ability
to meet our obligations and pay future dividends."

                        DESCRIPTION OF THE EQUITY UNITS

     The following is a summary of the terms of the Equity Units. This summary,
together with the summary of some of the provisions of the related documents
described below, contains a description of all of the material terms of the
Equity Units but is not necessarily complete. We refer you to the copies of
those documents which have been or will be filed and incorporated by reference
in the registration statement of which this prospectus supplement and the
accompanying prospectus form a part. This summary supplements the description of
the stock purchase units in the accompanying prospectus, and, to the extent it
is inconsistent, replaces the description in the accompanying prospectus. All
references in this prospectus supplement to our common stock include the rights
evidenced by such common stock to the extent provided in the Rights Agreement
dated as of March 12, 1999 between Chubb and EquiServe Trust Company, N.A.

     We will issue the Equity Units under the purchase contract agreement
between us and Bank One Trust Company, N.A., which we refer to as the purchase
contract agent. Equity Units may be either Corporate Units or Treasury Units.
The Equity Units will initially consist of 16,000,000 Corporate Units (or
18,400,000 Corporate Units if the underwriters exercise their option in full to
purchase additional Corporate Units), each with a stated amount of $25.

CORPORATE UNITS

     Each Corporate Unit will represent:

          (a) a purchase contract under which

             (1) the holder will agree to purchase from us, and we will agree to
        sell to the holder, not later than August 16, 2006, which we refer to as
        the purchase contract settlement date, for a stated amount of $25 in
        cash, a number of newly issued shares of our common stock equal to the
        settlement rate described below under "Description of the Purchase
        Contracts -- Purchase of Common Stock," subject to anti-dilution
        adjustments, and

             (2) we will pay the holder quarterly contract adjustment payments
        at the rate of      % per year on the stated amount of $25 per purchase
        contract, or $     per year; and

          (b) either:

             (1) a senior note issued by us having a $25 principal amount on
        which we will pay quarterly interest payments at a rate of      % per
        year; or

             (2) following a successful remarketing of the senior notes prior to
        the third business day immediately preceding the purchase contract
        settlement date, or the occurrence of a special event redemption, the
        applicable ownership interest in a portfolio of U.S. Treasury
        securities, which we refer to as the Treasury portfolio.

     "Applicable ownership interest" means, with respect to a Corporate Unit and
the U.S. Treasury securities in the Treasury portfolio,

             (1) a 2.5% undivided beneficial ownership interest in $1,000 face
        amount of U.S. Treasury securities (or principal or interest strips
        thereof) included in the Treasury portfolio that matures on or prior to
        August 15, 2006, and

             (2) for the scheduled interest payment date on the senior notes
        that occurs on the purchase contract settlement date, in the case of a
        successful remarketing of the senior note represented by that Corporate
        Unit prior to the third business day immediately preceding the purchase
        contract settlement date, or for each scheduled interest payment date on
        the senior notes after the date of a special event redemption and on or
        before the purchase contract settlement date, in the case of a special
        event redemption, a      % undivided beneficial ownership interest in
        $1,000 face amount of U.S. Treasury securities (or principal or interest
        strips thereof) included in the

                                       S-35


        Treasury portfolio that mature on or prior to the business day
        immediately preceding such payment date.

     The purchase price of each Equity Unit will be allocated between the
related purchase contract and the related senior note in proportion to their
respective fair market values at the time of issuance. We expect that, at the
time of issuance, the fair market value of each senior note will be $  and the
fair market value of each purchase contract will be $     . This position
generally will be binding on each beneficial owner of each Equity Unit but not
on the IRS.

     As long as a unit is in the form of a Corporate Unit, your senior note or
the appropriate applicable ownership interest in the Treasury portfolio, as
applicable, represented by the Corporate Unit will be held by the collateral
agent and pledged to secure your obligation to purchase common stock under the
related purchase contract.

CREATING TREASURY UNITS

     Unless the Treasury portfolio has replaced the senior notes as a component
of the Corporate Units as a result of a successful remarketing prior to the
third business day preceding the purchase contract settlement date or a special
event redemption prior to the purchase contract settlement date, each holder of
Corporate Units will have the right, at any time on or prior to the fifth
business day immediately preceding the purchase contract settlement date, to
substitute for the related senior notes held by the collateral agent,
zero-coupon Treasury securities that mature on either July 15, 2006 (CUSIP No.
          ) or August 15, 2006 (CUSIP No.           ), both of which we refer to
as a Treasury security, in a total principal amount at maturity equal to the
aggregate principal amount of the senior notes for which substitution is being
made. With respect to the Treasury securities maturing on July 15, 2006, during
the period between July 15, 2006 and August 15, 2006, any references to the
Treasury securities shall mean the cash proceeds paid upon maturity of such
Treasury securities.

     Because Treasury securities are issued in integral multiples of $1,000,
holders of Corporate Units may make this substitution only in integral multiples
of 40 Corporate Units.

     If the Treasury portfolio has replaced the senior notes as a component of
the Corporate Units, holders of Corporate Units will have the right, at any time
on or prior to the second business day immediately preceding the purchase
contract settlement date, to substitute Treasury securities for the applicable
ownership interest in the Treasury portfolio as a component of the Corporate
Units, but holders of Corporate Units can only make this substitution in
integral multiples of           Corporate Units. Each of these substitutions
will create Treasury Units, and the applicable senior notes or applicable
ownership interest in the Treasury portfolio will be released to the holder and
be separately tradable from the Treasury Units.

     Each Treasury Unit will represent:

          (a) a purchase contract under which

             (1) the holder will agree to purchase from us, and we will agree to
        sell to the holder, not later than the purchase contract settlement
        date, for the stated amount, a number of newly issued shares of our
        common stock equal to the settlement rate, subject to anti-dilution
        adjustments, and

             (2) we will pay the holder quarterly contract adjustment payments
        at the rate of      % per year on the stated amount of $25 per purchase
        contract, or $     per year; and

          (b) a 2.5% undivided beneficial interest in a Treasury security with a
     principal amount of $1,000.

     To create 40 Treasury Units, unless the Treasury portfolio has replaced the
senior notes as a component of the Corporate Units, the Corporate Unit holder
will:

     - deposit with the collateral agent a Treasury security that has a
       principal amount at maturity of $1,000, which must be purchased in the
       open market at the Corporate Unit holder's expense; and

                                       S-36


     - transfer 40 Corporate Units to the purchase contract agent accompanied by
       a notice stating that the holder has deposited a Treasury security with
       the collateral agent and requesting the release to the holder of the
       senior notes relating to the 40 Corporate Units.

     Upon the deposit and receipt of an instruction from the purchase contract
agent, the collateral agent will release the related senior notes from the
pledge under the pledge agreement, free and clear of our security interest, to
the purchase contract agent. The purchase contract agent then will:

     - cancel the 40 Corporate Units;

     - transfer the related senior notes to the holder; and

     - deliver 40 Treasury Units to the holder.

     The Treasury security will be substituted for the senior notes and will be
held by the collateral agent and pledged to secure the holder's obligation to
purchase common stock under the related purchase contracts. With respect to the
Treasury securities maturing on July 15, 2006, the cash proceeds paid upon the
maturity of such Treasury securities shall be pledged to secure the Treasury
Unit holders' obligations under the related purchase contracts. Such cash
proceeds shall be promptly invested by the collateral agent in certain permitted
investments for the benefit of the Treasury Unit holders. The related senior
notes released to the holder thereafter will trade separately from the resulting
Treasury Units.

     If the Treasury portfolio has replaced the senior notes as a component of
the Corporate Units, the Corporate Unit holder will follow the same procedure to
create a Treasury Unit, except the holder will have to deposit integral
multiples of           Corporate Units.

RECREATING CORPORATE UNITS

     Unless the Treasury portfolio has replaced the senior notes as a component
of the Corporate Units, each holder of Treasury Units will have the right, at
any time on or prior to the fifth business day immediately preceding the
purchase contract settlement date, to substitute for the related Treasury
securities held by the collateral agent, senior notes having a principal amount
equal to the aggregate principal amount at stated maturity of the Treasury
securities for which substitution is being made.

     Because Treasury securities are issued in integral multiples of $1,000,
holders of Treasury Units may make these substitutions only in integral
multiples of 40 Treasury Units.

     If the Treasury portfolio has replaced the senior notes as a component of
the Corporate Units, holders of Treasury Units will have the right, at any time
on or prior to the second business day immediately preceding the purchase
contract settlement date, to substitute the applicable ownership interests in
the Treasury portfolio for the Treasury securities that were represented by the
Treasury Units, but holders of Treasury Units can only make this substitution in
integral multiples of           Treasury Units.

     Each of these substitutions will recreate Corporate Units, and the
applicable Treasury securities will be released to the holder and be separately
tradable from the Corporate Units.

     To create 40 Corporate Units, unless the Treasury portfolio has replaced
the senior notes as a component of the Corporate Units, the Treasury Unit holder
will:

     - deposit with the collateral agent 40 senior notes, which must be
       purchased in the open market at the holder's expense unless otherwise
       owned by the holder; and

     - transfer 40 Treasury Unit certificates to the purchase contract agent
       accompanied by a notice stating that the Treasury Unit holder has
       deposited 40 senior notes with the collateral agent and requesting the
       release to the holder of the Treasury security relating to the Treasury
       Units.

                                       S-37


     Upon the deposit and receipt of an instruction from the purchase contract
agent, the collateral agent will release the related Treasury securities from
the pledge under the pledge agreement, free and clear of our security interest,
to the purchase contract agent. The purchase contract agent will then

     - cancel the 40 Treasury Units;

     - transfer the related Treasury security to the holder; and

     - deliver 40 Corporate Units to the holder.

     The substituted senior notes or the applicable ownership interests in the
Treasury portfolio will be held by the collateral agent and pledged to secure
the Corporate Unit holder's obligation to purchase common stock under the
related purchase contracts.

     If the Treasury portfolio has replaced the senior notes as a component of
the Corporate Units, the Treasury Unit holder will follow the same procedure to
create a Corporate Unit, except the holder will have to deposit integral
multiples of           Treasury Units.

     Holders that elect to substitute pledged securities, thereby creating
Treasury Units or recreating Corporate Units, will be responsible for any fees
or expenses payable in connection with the substitution.

CURRENT PAYMENTS

     Holders of Corporate Units will be entitled to receive quarterly cash
distributions consisting of interest payments calculated at the rate of      %
per year on senior notes (or distributions on the applicable ownership interest
in the Treasury portfolio if the senior notes have been replaced by the Treasury
portfolio) and, subject to our right to defer contract adjustment payments until
the date on which the purchase contracts are settled, contract adjustment
payments payable by us at the rate of      % per year on the stated amount of
$25 per purchase contract until the earlier of the purchase contract settlement
date and the most recent quarterly payment date on or before any early
settlement of the related purchase contracts. Subject to our right to defer
contract adjustment payments until the date on which the purchase contracts are
settled, holders of Treasury Units will be entitled to receive quarterly
contract adjustment payments payable by us at the rate of      % per year on the
stated amount of $25 per purchase contract until the earlier of the purchase
contract settlement date and the most recent quarterly payment date on or before
any early settlement of the related purchase contracts. There will be no
distributions in respect of the Treasury securities that are represented by the
Treasury Units, but the holders of the Treasury Units will continue to receive
the scheduled quarterly interest payments on the senior notes that were released
to them when the Treasury Units were created for as long as they hold the senior
notes.

RANKING

     Our obligations with respect to the senior notes will be senior and
unsecured and will rank equally with all of our other unsecured and
unsubordinated obligations. The indenture under which the senior notes will be
issued will not limit our ability to issue or incur other debt or issue
preferred stock. See "Description of the Senior Notes" below and "Description of
Debt Securities" in the accompanying prospectus.

     Our obligations with respect to the contract adjustment payments will be
subordinate in right of payment to our indebtedness.

VOTING AND CERTAIN OTHER RIGHTS

     Holders of purchase contracts represented by Corporate Units or Treasury
Units, in their capacities as such holders, will have no voting or other rights
in respect of the common stock.

                                       S-38


LISTING OF THE SECURITIES

     We will apply to list the Corporate Units on the New York Stock Exchange,
but no assurances can be given that the application for listing will be
approved. Unless and until substitution has been made as described in
"-- Creating Treasury Units" or "-- Recreating Corporate Units," neither the
senior notes nor the applicable ownership interest in the Treasury portfolio
component of a Corporate Unit will trade separately from the Corporate Units.
The senior notes or the applicable ownership interest in the Treasury portfolio
component will trade as a unit with the purchase contract component of the
Corporate Units. If the Treasury Units or the senior notes are separately traded
to a sufficient extent that applicable exchange listing requirements are met, we
will try to list the Treasury Units or the senior notes on the New York Stock
Exchange or any other applicable exchange or market.

MISCELLANEOUS

     We or our affiliates may from time to time purchase Corporate Units,
Treasury Units or senior notes outstanding by tender, in the open market or by
private agreement.

                                       S-39


                     DESCRIPTION OF THE PURCHASE CONTRACTS

     This section summarizes some of the terms of the purchase contract
agreement, purchase contracts, pledge agreement, remarketing agreement and
indenture. The summary should be read together with the purchase contract
agreement, pledge agreement, remarketing agreement and indenture, forms of which
have been or will be filed and incorporated by reference as exhibits to the
registration statement of which this prospectus supplement and the accompanying
prospectus form a part.

PURCHASE OF COMMON STOCK

     Each purchase contract represented by a Corporate Unit or Treasury Unit
will obligate the holder of the purchase contract to purchase, and us to sell,
on the purchase contract settlement date, for an amount in cash equal to the
stated amount, a number of newly issued shares of our common stock equal to the
"settlement rate." The settlement rate will be calculated, subject to adjustment
under the circumstances described in "-- Anti-Dilution Adjustments," as follows:

     - If the applicable market value of our common stock is greater than the
       threshold appreciation price of $       , the settlement rate will
       be          shares of our common stock per purchase contract, which is
       equal to the stated amount divided by the threshold appreciation price.

     Accordingly, if the market value for the common stock increases between the
date of this prospectus supplement and the period during which the applicable
market value is measured and the applicable market value is greater than the
threshold appreciation price, the aggregate market value of the shares of common
stock issued upon settlement of each purchase contract will be higher than the
stated amount, assuming that the market price of the common stock on the
purchase contract settlement date is the same as the applicable market value of
the common stock.

     - If the applicable market value of our common stock is less than or equal
       to the threshold appreciation price but greater than or equal to the
       reference price of $          , the settlement rate will be a number of
       shares of our common stock per purchase contract equal to $25 divided by
       the applicable market value.

     Accordingly, if the market value for the common stock does not change or
increases between the date of this prospectus supplement and the period during
which the applicable market value is measured, but the applicable market value
does not exceed the threshold appreciation price, the aggregate market value of
the shares of common stock issued upon settlement of each purchase contract will
be equal to the stated amount, assuming that the market price of the common
stock on the purchase contract settlement date is the same as the applicable
market value of the common stock.

     - If the applicable market value of our common stock is less than the
       reference price, the settlement rate will be          shares of our
       common stock per purchase contract, which is equal to the stated amount
       divided by the reference price.

     Accordingly, if the market value for the common stock decreases between the
date of this prospectus supplement and the period during which the applicable
market value is measured and the applicable market value is less than the
reference price, the aggregate market value of the shares of common stock issued
upon settlement of each purchase contract will be less than the stated amount,
assuming that the market price on the purchase contract settlement date is the
same as the applicable market value of the common stock.

     "Applicable market value" means the average of the closing price per share
of our common stock on each of the twenty consecutive trading days ending on the
third trading day immediately preceding the purchase contract settlement date,
subject to adjustment under the circumstances set forth in "-- Anti-Dilution
Adjustments." The reference price is expected to be the reported last sale price
of our common stock on the New York Stock Exchange on the date we price the
offering of the purchase contracts and senior notes. The threshold appreciation
price represents a      % appreciation over the reference price.

                                       S-40


     "Closing price" of the common stock on any date of determination means the
closing sale price (or, if no closing price is reported, the last reported sale
price) of the common stock on the New York Stock Exchange on that date or, if
the common stock is not listed for trading on the New York Stock Exchange on any
such date, as reported in the composite transactions for the principal United
States securities exchange on which the common stock is so listed. If the common
stock is not so listed on a United States national or regional securities
exchange, the closing price means the last closing sale price of the common
stock as reported by the Nasdaq National Market, or, if the common stock is not
so reported, the last quoted bid price for the common stock in the
over-the-counter market as reported by the National Quotation Bureau or similar
organization. If the bid price is not available, the closing price means the
market value of the common stock on the date of determination as determined by a
nationally recognized independent investment banking firm retained by us for
this purpose.

     A "trading day" means a day on which the common stock

     - is not suspended from trading on any national or regional securities
       exchange or association or over-the-counter market at the close of
       business, and

     - has traded at least once on the national or regional securities exchange
       or association or over-the-counter market that is the primary market for
       the trading of the common stock.

     We will not issue any fractional shares of common stock pursuant to the
purchase contracts. In lieu of fractional shares otherwise issuable (calculated
on an aggregate basis) in respect of purchase contracts being settled by a
holder of Corporate Units or Treasury Units, the holder will be entitled to
receive an amount of cash equal to the fraction of a share times the applicable
market value.

     On the business day immediately preceding the purchase contract settlement
date, unless:

     - a holder of Corporate Units or Treasury Units has settled the related
       purchase contracts prior to the purchase contract settlement date through
       the early delivery of cash to the purchase contract agent in the manner
       described under "-- Early Settlement," or "-- Early Settlement Upon Cash
       Merger,"

     - a holder of Corporate Units that include senior notes has settled the
       related purchase contracts with separate cash on the fourth business day
       immediately preceding the purchase contract settlement date pursuant to
       prior notice given in the manner described under "-- Notice to Settle
       with Cash," or

     - an event described under "-- Termination" has occurred,

then,

     - in the case of Corporate Units where the Treasury portfolio has replaced
       the senior notes, proceeds equal to the stated amount of $25 per
       Corporate Unit when paid at maturity, of the appropriate applicable
       ownership interest of the Treasury portfolio will automatically be
       applied to satisfy in full the holder's obligation to purchase common
       stock under the related purchase contracts,

     - in the case of Corporate Units where the Treasury portfolio has not
       replaced the senior notes as a component of the Corporate Units and there
       has been a successful final remarketing of the senior notes, the portion
       of the proceeds from the remarketing equal to the principal amount of the
       senior notes remarketed will automatically be applied to satisfy in full
       the holder's obligation to purchase shares of our common stock under the
       related purchase contracts,

     - in the case of Corporate Units where the Treasury portfolio has not
       replaced the senior notes as a component of the Corporate Units and there
       has not been a successful remarketing of the senior notes, we will
       exercise our rights as a secured party to retain the senior notes pledged
       as collateral or dispose of them in accordance with applicable law and,
       following such action, the Corporate Unit holder's obligations to
       purchase shares of our common stock under the related purchase contracts
       on the purchase contract settlement date will be satisfied in full, and

                                       S-41


     - in the case of Treasury Units, the principal amount of the related
       Treasury securities, when paid at maturity, will automatically be applied
       to satisfy in full the holder's obligation to purchase common stock under
       the related purchase contracts.

     The common stock will then be issued and delivered to the holder or the
holder's designee, upon presentation and surrender of the certificate evidencing
the Corporate Units or Treasury Units and payment by the holder of any transfer
or similar taxes payable in connection with the issuance of the common stock to
any person other than the holder.

     Each holder of Corporate Units or Treasury Units, by acceptance of these
securities, will be deemed to have:

     - irrevocably agreed to be bound by the terms and provisions of the related
       purchase contracts and the pledge agreement and to have agreed to perform
       its obligations thereunder for so long as the holder remains a holder of
       the Corporate Units or Treasury Units; and

     - duly appointed the purchase contract agent as the holder's
       attorney-in-fact to enter into and perform the related purchase contracts
       and pledge agreement on behalf of and in the name of the holder.

     In addition, each beneficial owner of Corporate Units or Treasury Units, by
acceptance of the beneficial interest therein, will be deemed to have agreed to
treat

     - itself as the owner of the related senior notes, applicable ownership
       interests in the Treasury portfolio or the Treasury securities, as the
       case may be, and

     - the senior notes as our indebtedness for all United States federal, state
       and local tax purposes.

REMARKETING

     Pursuant to the remarketing agreement that we will enter into with the
purchase contract agent and the remarketing agent, and subject to the terms of
the remarketing agreement among the remarketing agent, the purchase contract
agent and us, unless a special event redemption has occurred, the senior notes
held by Corporate Unit holders as part of a Corporate Unit will be remarketed on
the third business day immediately preceding May 16, 2006 (the date three months
prior to the purchase contract settlement date), which we refer to as the
initial remarketing date. We currently expect the remarketing agent will be one
or more of Citigroup, Goldman, Sachs & Co. and Merrill Lynch & Co.

     The remarketing agent will use its reasonable efforts to obtain a price for
the remarketed senior notes of approximately (but not less than) 100.50% of the
purchase price for the Treasury portfolio described below. To obtain that price,
the remarketing agent may reset the interest rate on the senior notes, as
described under "Description of the Senior Notes."

     If the remarketing of the senior notes on the initial remarketing date
fails or does not settle for any reason, the senior notes will continue to be
represented by Corporate Units and the remarketing agent will use its reasonable
efforts to remarket the senior notes on the third business day immediately
preceding June 16, 2006, which we call the second remarketing date, and on the
third business day immediately preceding July 16, 2006, which we call the third
remarketing date, in each case at a price of approximately (but not less than)
100.50% of the purchase price of the Treasury portfolio.

     Following a successful remarketing of the senior notes on any of these
remarketing dates, the portion of the proceeds from the remarketing equal to the
Treasury portfolio purchase price will be applied to purchase the Treasury
portfolio consisting of:

     - U.S. Treasury securities (or principal or interest strips thereof) that
       mature on or prior to August 15, 2006, in an aggregate amount equal to
       the principal amount of the senior notes represented by Corporate Units;
       and

                                       S-42


     - U.S. Treasury securities (or principal or interest strips thereof) that
       mature on or prior to August 15, 2006 in an aggregate amount equal to the
       aggregate interest payment (assuming no reset of the interest rate) that
       would have been paid to the holders of Corporate Units on the purchase
       contract settlement date on the aggregate principal amount of the senior
       notes represented by the Corporate Units.

     The Treasury portfolio will be substituted for the senior notes as a
component of the Corporate Units and will be held by the collateral agent and
pledged to secure the Corporate Unit holders' obligations under the purchase
contracts. On the purchase contract settlement date, a portion of the proceeds
from the Treasury portfolio equal to the principal amount of the senior notes
represented by the Corporate Units at the time of remarketing will automatically
be applied to satisfy the Corporate Unit holders' obligation to purchase common
stock under the purchase contracts and proceeds from the Treasury portfolio
equal to the interest payment (assuming no reset of the interest rate) that
would have been paid to the holders of Corporate Units on the senior notes
represented by the Corporate Units at the time of remarketing on the purchase
contract settlement date will be paid to the holders of the Corporate Units.

     The remarketing agent will deduct, as a remarketing fee, an amount not
exceeding 25 basis points (.25%) of the Treasury portfolio purchase price from
any proceeds from the remarketing of the senior notes in excess of the Treasury
portfolio purchase price. The remarketing agent will then remit any remaining
portion of the proceeds for the benefit of the holders of the senior notes
included in the remarketing.

     As used in this context, "Treasury portfolio purchase price" means the
lowest aggregate ask-side price quoted by a primary U.S. government securities
dealer to the quotation agent between 9:00 a.m. and 11:00 a.m., New York City
time, on the date of a successful remarketing for the purchase of the Treasury
portfolio described above for settlement the third business day immediately
following such date. "Quotation agent" means any primary U.S. government
securities dealer in New York City selected by us.

     If a successful remarketing of the senior notes has not occurred on or
prior to the third remarketing date, the remarketing agent will use its
reasonable efforts to remarket the senior notes on the third business day
immediately preceding the purchase contract settlement date, which we refer to
as the final remarketing date, at a price of approximately 100.50% of the
principal amount of the senior notes remarketed, but remarketing on the final
remarketing date will be considered successful and no further attempts will be
made if the resulting proceeds (net of fees and commissions, if any) are at
least 100% of the aggregate principal amount of the senior notes.

     If the remarketing of the senior notes on the final remarketing date is
successful, a portion of the proceeds from this remarketing equal to the
aggregate principal amount of the senior notes represented by the Corporate
Units at the time of remarketing will automatically be applied to satisfy in
full the Corporate Unit holders' obligations to purchase common stock under the
related purchase contracts on the purchase contract settlement date. The
remarketing agent will deduct, as a remarketing fee, an amount not exceeding 25
basis points (.25%) of the aggregate principal amount of the remarketed senior
notes from any proceeds from the remarketing in excess of the aggregate
principal amount of the senior notes remarketed. The remarketing agent will then
remit any remaining portion of the proceeds for the benefit of the holders of
the senior notes included in the remarketing.

     Following a successful remarketing prior to the third business day
immediately preceding the purchase contract settlement date, holders of Treasury
Units can recreate a Corporate Unit at any time prior to the second business day
immediately preceding the purchase contract settlement date as described under
"Description of the Equity Units--Recreating Corporate Units."

     We will cause a notice of any failed remarketing to be published on the
business day immediately following the applicable remarketing date, by
publication in a daily newspaper in the English language of general circulation
in The City of New York, which is expected to be The Wall Street Journal. In
addition, we will request, not later than seven nor more than 15 calendar days
prior to the applicable remarketing date, that the depositary notify its
participants holding senior notes, Corporate Units and

                                       S-43


Treasury Units of the remarketing, including, in the case of a failed
remarketing on the final remarketing date, the procedures that must be followed
if a senior note holder wishes to exercise its right to put its senior note to
us as described in this prospectus supplement. If required, we will use
commercially reasonable efforts to ensure that a registration statement covering
the full amount of the senior notes to be remarketed will be effective in a form
that will enable the remarketing agent to rely on it in connection with the
remarketing process.

     If a successful remarketing of the senior notes represented by your
Corporate Units has not occurred on or prior to the final remarketing date, we
will deliver our common stock to you pursuant to the purchase contracts and,
unless you have delivered the stated amount in respect of the purchase contracts
represented by your Corporate Units to us in cash before the final remarketing
date, we will exercise our rights as a secured party with respect to the senior
notes that have been pledged to us through the collateral agent to secure your
obligation under the related purchase contracts, and your obligation under these
purchase contracts will be deemed to be satisfied in full. In addition, holders
of senior notes that remain outstanding will have the right to put their senior
notes to us for $25 per senior note, plus accrued and unpaid interest, on
September 30, 2006, which we call the exercise date, by notifying the indenture
trustee on or prior to the fifth business day before the exercise date.

     If you hold Corporate Units, you may elect not to participate in any
remarketing and to retain the senior notes represented by your Corporate Units
by (1) creating Treasury Units at any time on or prior to the second business
day prior to any of the remarketing dates or (2) if the first three remarketing
attempts have failed, notifying the purchase contract agent of your intention to
pay cash to satisfy your obligation under the related purchase contracts on or
prior to the fifth business day before the purchase contract settlement date and
delivering the cash payment required under the purchase contracts to the
collateral agent on or prior to the fourth business day before the purchase
contract settlement date.

EARLY SETTLEMENT

     Subject to the conditions described below, a holder of Corporate Units or
Treasury Units may settle the related purchase contracts in cash at any time on
or prior to the fifth business day immediately preceding the purchase contract
settlement date by presenting and surrendering the related Corporate Unit or
Treasury Units certificate, if they are in certificated form, at the offices of
the purchase contract agent with the form of "Election to Settle Early" on the
reverse side of such certificate completed and executed as indicated,
accompanied by payment to us in immediately available funds of an amount equal
to

     - the stated amount times the number of purchase contracts being settled,
       plus

     - if the delivery is made with respect to any purchase contract during the
       period from the close of business on any record date next preceding any
       payment date to the opening of business on such payment date, an amount
       equal to the contract adjustment payments payable on the payment date
       with respect to the purchase contract.

     If the Treasury portfolio has replaced the senior notes as a component of
Corporate Units, holders of the Corporate Units may settle early only in
integral multiples of           Corporate Units. Holders of Treasury Units may
settle early only in integral multiples of 40 Treasury Units.

     So long as the Equity Units are evidenced by one or more global security
certificates deposited with the depositary, procedures for early settlement will
also be governed by standing arrangements between the depositary and the
purchase contract agent. The early settlement right is also subject to the
condition that, if required under the U.S. federal securities laws, we have a
registration statement under the Securities Act of 1933 in effect covering the
shares of common stock and other securities, if any, deliverable upon settlement
of a purchase contract. We have agreed that, if required under the U.S. federal
securities laws, we will (1) use commercially reasonable efforts to have a
registration statement in effect covering those shares of common stock and other
securities to be delivered in respect of the purchase contracts being settled
and (2) provide a prospectus in connection therewith, in each case in a form
that may be used in connection with the early settlement right.

                                       S-44


     Upon early settlement of the purchase contracts represented by any
Corporate Units or Treasury Units:

     - except as described below in "-- Early Settlement Upon Cash Merger," the
       holder will receive                newly issued shares of common stock
       per Corporate Unit or Treasury Unit, subject to adjustment under the
       circumstances described under "-- Anti-Dilution Adjustments," accompanied
       by an appropriate prospectus if required by law;

     - the senior notes, the applicable ownership interest in the Treasury
       portfolio or the Treasury securities, as the case may be, related to the
       Corporate Units or Treasury Units will be transferred to the holder free
       and clear of our security interest;

     - the holder's right to receive future contract adjustment payments will
       terminate; and

     - no adjustment will be made to or for the holder on account of any amounts
       accrued in respect of contract adjustment payments.

     If the purchase contract agent receives a Corporate Unit certificate or
Treasury Unit certificate if they are in certificated form accompanied by the
completed "Election to Settle Early" and required immediately available funds,
from a holder of Corporate Units or Treasury Units by 5:00 p.m., New York City
time, on a business day and all conditions to early settlement have been
satisfied, that day will be considered the settlement date. If the purchase
contract agent receives the above after 5:00 p.m., New York City time, on a
business day or at any time on a day that is not a business day, the next
business day will be considered the settlement date.

     Upon early settlement of purchase contracts in the manner described above,
presentation and surrender of the certificate evidencing the related Corporate
Units or Treasury Units if they are in certificated form and payment of any
transfer or similar taxes payable by the holder in connection with the issuance
of the related common stock to any person other than the holder of the Corporate
Units or Treasury Units, we will cause the shares of common stock being
purchased to be issued, and the related senior notes, the applicable ownership
interest in the Treasury portfolio or the Treasury securities, as the case may
be, securing the purchase contracts to be released from the pledge under the
pledge agreement described in "-- Pledged Securities and Pledge Agreement" and
transferred, within three business days following the settlement date, to the
purchasing holder or the holder's designee.

NOTICE TO SETTLE WITH CASH

     Unless the Treasury portfolio has replaced the senior notes as a component
of Corporate Units, a holder of Corporate Units may settle the related purchase
contract with separate cash. A holder of a Corporate Unit wishing to settle the
related purchase contract with separate cash must notify the purchase contract
agent by presenting and surrendering the Corporate Unit certificate evidencing
the Corporate Unit at the offices of the purchase contract agent with the form
of "Notice to Settle by Separate Cash" on the reverse side of the certificate
completed and executed as indicated on or prior to 5:00 p.m., New York City
time, on the fifth business day immediately preceding the purchase contract
settlement date and delivering the required cash payment to the collateral agent
on or prior to 5:00 p.m., New York City time, on the fourth business day
immediately preceding the purchase contract settlement date.

     If a holder that has given notice of its intention to settle the related
purchase contract with separate cash fails to deliver the cash to the collateral
agent on the fourth business day immediately preceding the purchase contract
settlement date, such holder's senior notes will be included in the final
remarketing of senior notes occurring on the third business day immediately
preceding the purchase contract settlement date. If such final remarketing is
unsuccessful, we will exercise our rights as a secured party with respect to the
senior notes that have been pledged to us through the collateral agent to secure
the holder's obligation under the purchase contracts, and the holder's
obligation under the purchase contract will be deemed to be satisfied in full.

                                       S-45


EARLY SETTLEMENT UPON CASH MERGER

     Prior to the purchase contract settlement date, if we are involved in a
merger in which at least 30% of the consideration for our common stock consists
of cash or cash equivalents, which we refer to as a cash merger, then following
the cash merger, each holder of a purchase contract will have the right to
accelerate and settle such purchase contract early at the settlement rate in
effect immediately prior to the closing of the cash merger, provided that at
such time, if so required under the U.S. federal securities laws, there is in
effect a registration statement covering the common stock and other securities,
if any, to be delivered in respect of the purchase contracts being settled. We
refer to this right as the "merger early settlement right."

     We will provide each of the holders with a notice of the completion of a
cash merger within five business days thereof. The notice will specify a date,
which shall be 10 days after the date of the notice but no later than five
business days prior to the purchase contract settlement date by which each
holder's merger early settlement right must be exercised. The notice will set
forth, among other things, the applicable settlement rate and the amount of the
cash, securities and other consideration receivable by the holder upon
settlement. To exercise the merger early settlement right, you must deliver to
the purchase contract agent, three business days before the early settlement
date, the certificate evidencing your Corporate Units or Treasury Units if they
are held in certificated form, and payment of the applicable purchase price in
immediately available funds.

     If you exercise the merger early settlement right, we will deliver to you
on the early settlement date the kind and amount of securities, cash or other
property that you would have been entitled to receive if you had settled the
purchase contract immediately before the cash merger at the settlement rate in
effect at such time. You will also receive the senior notes, applicable
ownership interests in the Treasury portfolio or Treasury securities represented
by the Corporate Units or Treasury Units, as the case may be. If you do not
elect to exercise your merger early settlement right, your Corporate Units or
Treasury Units will remain outstanding and subject to normal settlement on the
settlement date. We have agreed that, if required under the U.S. federal
securities laws, we will use commercially reasonable efforts to (1) have in
effect a registration statement covering the common stock and other securities,
if any, to be delivered in respect of the purchase contracts being settled and
(2) provide a prospectus in connection therewith, in each case in a form that
may be used in connection with the early settlement upon a cash merger.

     If the Treasury portfolio has replaced the senior notes as a component of
Corporate Units, holders of the Corporate Units may exercise the merger early
settlement right only in integral multiples of           Corporate Units. A
holder of Treasury Units may exercise the merger early settlement right only in
integral multiples of 40 Treasury Units.

CONTRACT ADJUSTMENT PAYMENTS

     Contract adjustment payments will be fixed at a rate per year of      % of
the stated amount of $25 per purchase contract. Contract adjustment payments
payable for any period will be computed on the basis of a 360-day year of twelve
30-day months. Contract adjustment payments will accrue from June   , 2003 and
will be payable quarterly in arrears on February 16, May 16, August 16 and
November 16 of each year, commencing August 16, 2003. We have the right to defer
the payment of these contract adjustment payments as described below under
"-- Option to Defer Contract Adjustment Payments."

     Contract adjustment payments will be payable to the holders of purchase
contracts as they appear on the books and records of the purchase contract agent
at the close of business on the relevant record dates, which will be on the
first day of the month in which the relevant payment date falls. These
distributions will be paid through the purchase contract agent, who will hold
amounts received in respect of the contract adjustment payments for the benefit
of the holders of the purchase contracts relating to the Equity Units. Subject
to any applicable laws and regulations, each such payment will be made as
described under "-- Book-Entry System."

                                       S-46


     If any date on which contract adjustment payments are to be made on the
purchase contracts represented by the Equity Units is not a business day, then
payment of the contract adjustment payments payable on that date will be made on
the next succeeding day that is a business day, and no interest or payment will
be paid in respect of the delay. However, if that business day is in the next
succeeding calendar year, that payment will be made on the immediately preceding
business day, in each case with the same force and effect as if made on that
payment date. A business day means any day other than a Saturday, Sunday or any
other day on which banking institutions and trust companies in the City of New
York are permitted or required by any applicable law to close.

     Our obligations with respect to contract adjustment payments will be
subordinated and junior in right of payment to our obligations under any of our
indebtedness.

OPTION TO DEFER CONTRACT ADJUSTMENT PAYMENTS

     We may, at our option and upon prior written notice to the holders of
Equity Units and the purchase contract agent, defer the payment of contract
adjustment payments on each related purchase contract forming a part of an
Equity Unit until no later than the purchase contract settlement date or, if
applicable, the date of any earlier settlement of the purchase contract.
However, deferred contract adjustment payments will bear additional contract
adjustment payments at the rate of      % per year (compounding on each
succeeding payment date) until paid. If the purchase contracts are terminated
(upon the occurrence of certain events of bankruptcy, insolvency or
reorganization with respect to us), the right to receive future contract
adjustment payments will also terminate.

     In the event that we elect to defer the payment of contract adjustment
payments on the purchase contracts, each holder of Equity Units will receive, on
the earlier of the purchase contract settlement date and the date of any earlier
settlement of the purchase contract, the aggregate amount of deferred contract
adjustment payments on the related purchase contract in cash to the extent such
amounts are not deducted from the stated amount payable to us.

     In the event we exercise our option to defer the payment of contract
adjustment payments, then until the deferred contract adjustment payments have
been paid, we will not, and will not permit our subsidiaries to, declare or pay
dividends on, make other distributions with respect to, or redeem, purchase or
acquire, or make a liquidation payment with respect to, any of our capital
shares or their capital shares; provided that the foregoing will not restrict
any of our subsidiaries from declaring or paying such dividends, or making such
distributions, to us or any of our other subsidiaries.

ANTI-DILUTION ADJUSTMENTS

     The formula for determining the settlement rate will be subject to
adjustment, without duplication, upon the occurrence of certain events,
including:

          (a) the payment of stock dividends and distributions of shares of
     common stock on the outstanding shares of common stock;

          (b) the issuance to all holders of outstanding shares of common stock
     of rights, warrants or options (other than pursuant to any dividend
     reinvestment or share purchase plans) entitling them, for a period of up to
     45 days, to subscribe for or purchase shares of common stock at less than
     the current market price thereof;

          (c) subdivisions, splits and combinations of shares of common stock;

          (d) distributions to all holders of outstanding shares of common stock
     of evidences of our indebtedness, shares of capital stock, securities, cash
     or property (excluding any dividend or distribution covered by clause (a)
     or (b) above and any dividend or distribution paid exclusively in cash);

          (e) distributions (other than regular quarterly cash distributions)
     consisting exclusively of cash to all holders of outstanding shares of
     common stock in an aggregate amount that, together with

                                       S-47


     (1) other all-cash distributions (other than regular quarterly cash
     distributions) made within the preceding 12 months and (2) any cash and the
     fair market value, as of the expiration of the tender or exchange offer
     referred to below, of consideration payable in respect of any tender or
     exchange offer (other than consideration payable in respect of any odd-lot
     tender offer) by us or any of our subsidiaries for shares of common stock
     concluded within the preceding 12 months, exceeds 10% of our aggregate
     market capitalization (aggregate market capitalization being the product of
     the current market price of shares of common stock multiplied by the number
     of shares of common stock then outstanding) on the record date for such
     distribution; and

          (f) the successful completion of a tender or exchange offer made by us
     or any of our subsidiaries for shares of common stock which involves an
     aggregate consideration that, together with (1) any cash and the fair
     market value of other consideration payable in respect of any tender or
     exchange offer (other than consideration payable in respect of any odd-lot
     tender offer) by us or any of our subsidiaries for the common stock
     concluded within the preceding 12 months and (2) the aggregate amount of
     any all-cash distributions (other than regular quarterly cash
     distributions) to all holders of shares of common stock within the
     preceding 12 months, exceeds 10% of our aggregate market capitalization on
     the expiration of the tender or exchange offer.

     If the rights provided for in our rights agreement dated as of March 12,
1999 have separated from our common stock in accordance with the provisions of
the rights agreement so that the holders of the purchase contracts would not be
entitled to receive any rights in respect of the common stock issuable on the
purchase contract settlement date, the settlement rate will be adjusted as if we
distributed to all holders of our common stock, evidences of indebtedness,
shares of capital stock, securities, cash or property as described under clause
(d) above, subject to readjustment in the event of the expiration, termination
or redemption of the rights. In lieu of any such adjustment, we may amend our
rights agreement to provide that on the purchase contract settlement date the
holders will receive, in addition to the common stock issuable on such date, the
rights that would have attached to such shares of common stock if the rights had
not become separated from the common stock under our rights agreement. To the
extent that we adopt any future rights plan, on the purchase contract settlement
date, you will receive, in addition to the common stock, the rights under the
future rights plan whether or not the rights have separated from the common
stock on the purchase contract settlement date and no adjustment to the
settlement rate shall be made in accordance with clause (d) above.

     The "current market price" per share of common stock on any day means the
average of the daily closing prices on each of the 20 consecutive trading days
ending on the earlier of the day in question and the day before the "ex date"
with respect to the issuance or distribution requiring the computation. For
purposes of this paragraph, the term "ex date," when used with respect to any
issuance or distribution, will mean the first date on which the common stock
trades regular way on the applicable exchange or in the applicable market
without the right to receive the issuance or distribution.

     In the case of certain reclassifications, consolidations, mergers, sales or
transfers of assets or other transactions that cause our common stock to be
converted into the right to receive other securities, cash or property, each
purchase contract then outstanding would, without the consent of the holders of
the related Corporate Units or Treasury Units, as the case may be, become a
purchase contract with respect to such other securities, cash and property
instead of our common stock. Upon the occurrence of any such transaction, on the
purchase contract settlement date the settlement rate then in effect will be
applied to the value, on the purchase contract settlement date, of the
securities, cash or property a holder would have received had it held shares
covered by the purchase contract when such transaction occurred.

     If at any time we make a distribution of property to our stockholders that
would be taxable to the stockholders as a dividend for United States federal
income tax purposes (i.e., distributions out of our current or accumulated
earnings and profits or distributions of evidences of indebtedness or assets,
but generally not stock dividends or rights to subscribe for capital stock) and,
pursuant to the settlement rate adjustment provisions of the purchase contract
agreement, the settlement rate is increased, this increase may give rise to a
taxable dividend to holders of Corporate Units.

                                       S-48


     In addition, we may make increases in the settlement rate as our board of
directors deems advisable to avoid or diminish any income tax to holders of our
capital stock resulting from any dividend or distribution of capital stock (or
rights to acquire capital stock) or from any event treated as such for income
tax purposes or for any other reasons.

     Adjustments to the settlement rate will be calculated to the nearest
1/10,000th of a share. No adjustment in the settlement rate will be required
unless the adjustment would require an increase or decrease of at least one
percent in the settlement rate. However, any adjustments that are not required
to be made because they would have required an increase or decrease of less than
one percent will be carried forward and taken into account in any subsequent
adjustment.

     We will be required, within ten business days following the adjustment to
the settlement rate, to provide written notice to the purchase contract agent of
the occurrence of the adjustment and a statement in reasonable detail setting
forth the method by which the adjustment to the settlement rate was determined
and setting forth the revised settlement rate.

     Each adjustment to the settlement rate will result in a corresponding
adjustment to the number of shares of common stock issuable upon early
settlement of a purchase contract. Each adjustment to the settlement rate will
also result in an adjustment to the applicable market value to determine which
of the three clauses in the definition of settlement rate will be applicable on
the purchase contract settlement date or any cash merger early settlement date.

TERMINATION

     The purchase contracts, and our rights and obligations and the rights and
obligations of the holders of the Corporate Units and Treasury Units under the
purchase contracts, including the right and obligation to purchase shares of
common stock and the right to receive accrued contract adjustment payments, will
immediately and automatically terminate, without any further action, upon the
termination of the purchase contracts as a result of our bankruptcy, insolvency
or reorganization.

     Upon a termination of the purchase contracts, the collateral agent will
release the securities held by it to the purchase contract agent for
distribution to the holders. If a holder would otherwise have been entitled to
receive less than $1,000 principal amount at maturity of any Treasury security
upon termination of the purchase contract, the purchase contract agent will
dispose of the security for cash and pay the cash to the holder. Upon
termination, however, the release and distribution may be subject to a delay. If
we become the subject of a case under the federal bankruptcy code, a delay in
the release of the pledged senior notes or Treasury securities may occur as a
result of the automatic stay under the bankruptcy code and continue until the
automatic stay has been lifted. The automatic stay will not be lifted until such
time as the bankruptcy court agrees to lift it and permit the return of your
collateral to you. In such a case under the federal bankruptcy code, claims
arising out of the senior notes, like all other claims in bankruptcy
proceedings, will be subject to the jurisdiction and equitable powers of the
bankruptcy court.

     If the holder's purchase contract is terminated as a result of our
bankruptcy, insolvency or reorganization, such holder will have no right to
receive any accrued contract adjustment payments.

PLEDGED SECURITIES AND PLEDGE AGREEMENT

     Pledged securities will be held by the collateral agent, for our benefit,
pursuant to the pledge agreement and pledged to secure the obligations of
holders of Corporate Units and Treasury Units to purchase shares of common stock
under the related purchase contracts. The rights of holders of Corporate Units
and Treasury Units to the pledged securities represented by such Corporate Units
or Treasury Units will be subject to our security interest created by the pledge
agreement. The pledge agreement provides that if we are entitled to exercise our
rights as a secured party because the senior notes were not successfully
remarketed by purchase contract settlement date, we may retain the pledged
securities or dispose of them in accordance with applicable law in full
satisfaction of the secured obligations.

                                       S-49


     No holder of Corporate Units or Treasury Units will be permitted to
withdraw the pledged securities related to the Corporate Units or Treasury Units
from the pledge arrangement except:

     - to substitute Treasury securities for the related senior notes or the
       applicable ownership interest in the Treasury portfolio, as the case may
       be, as provided for under "Description of the Equity Units -- Creating
       Treasury Units;"

     - to substitute senior notes or the applicable ownership interest of the
       Treasury portfolio, as the case may be, for the related Treasury
       securities, as provided for under "Description of the Equity
       Units -- Recreating Corporate Units;" or

     - upon the termination or early settlement of the related purchase
       contracts.

     Subject to the security interest and the terms of the purchase contract
agreement and the pledge agreement, each holder of Corporate Units, unless the
Treasury portfolio has replaced the senior notes as a component of Corporate
Units, will be entitled through the purchase contract agent and the collateral
agent to all of the proportional rights of the related senior notes, including
voting and redemption rights. Each holder of Treasury Units and each holder of
Corporate Units, if the Treasury portfolio has replaced the senior notes as a
component of Corporate Units, will retain beneficial ownership of the related
Treasury securities or the applicable ownership interest of the Treasury
portfolio, as applicable, pledged in respect of the related purchase contracts.
We will have no interest in the pledged securities other than our security
interest.

     Except as described in "Certain Provisions of the Purchase Contracts, the
Purchase Contract Agreement and the Pledge Agreement -- General," the collateral
agent will, upon receipt, if any, of payments on the pledged securities,
distribute the payments to the purchase contract agent, which will in turn
distribute those payments, together with contract adjustment payments received
from us, to the persons in whose names the related Corporate Units or Treasury
Units are registered at the close of business on the record date immediately
preceding the date of payment. With respect to the Treasury securities maturing
on July 15, 2006, the cash proceeds paid upon maturity shall be pledged to
secure the Treasury Unit holders' obligations under the related purchase
contracts. Such cash proceeds shall be promptly invested by the collateral agent
in certain permitted investments for the benefit of the Treasury Unit holders.

BOOK-ENTRY SYSTEM

     The Depository Trust Company, which we refer to along with its successors
in this capacity as the depositary, will act as securities depositary for the
Corporate Units and Treasury Units. The Corporate Units and Treasury Units will
be issued only as fully registered securities registered in the name of Cede &
Co., the depositary's nominee. One or more fully registered global security
certificates, representing the total aggregate number of Corporate Units and
Treasury Units, will be issued and will be deposited with the depositary and
will bear a legend regarding the restrictions on exchanges and registration of
transfer referred to below.

     The laws of some jurisdictions may require that some purchasers of
securities take physical delivery of securities in definitive form. These laws
may impair the ability to transfer beneficial interests in the Corporate Units
or the Treasury Units so long as the Corporate Units or the Treasury Units are
represented by global security certificates.

     The depositary 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 Securities
Exchange Act of 1934. The depositary holds securities that its participants
deposit with the depositary. The depositary also facilitates the settlement
among participants of securities transactions, including transfers and pledges,
in deposited securities through electronic computerized book-entry changes in
participants' accounts, thereby eliminating the need for physical movement of
securities certificates. Direct participants

                                       S-50


include securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations. The depositary is owned by a
number of its direct participants and by the New York Stock Exchange, the
American Stock Exchange, Inc., and the National Association of Securities
Dealers, Inc. Access to the depositary's system is also available to others,
including securities brokers and dealers, banks and trust companies that clear
transactions through or maintain a direct or indirect custodial relationship
with a direct participant either directly, or indirectly. The rules applicable
to the depositary and its participants are on file with the SEC.

     In the event that

     - the depositary notifies us that it is unwilling or unable to continue as
       a depositary for the global security certificates and no successor
       depositary has been appointed within 90 days after this notice,

     - the depositary at any time ceases to be a clearing agency registered
       under the Securities Exchange Act of 1934 when the depositary is required
       to be so registered to act as the depositary and no successor depositary
       has been appointed within 90 days after we learn that the depositary has
       ceased to be so registered, or

     - we, in our sole discretion, determine that the global security
       certificates shall be so exchangeable,

certificates for the Corporate Units or Treasury Units will be printed and
delivered in exchange for beneficial interests in the global security
certificates. Any global Corporate Unit or Treasury Unit that is exchangeable
pursuant to the preceding sentence will be exchangeable for Corporate Unit or
Treasury Unit certificates registered in the names directed by the depositary.
We expect that these instructions will be based upon directions received by the
depositary from its participants with respect to ownership of beneficial
interests in the global security certificates.

     As long as the depositary or its nominee is the registered owner of the
global security certificates, the depositary or its nominee, as the case may be,
will be considered the sole owner and holder of the global security certificates
and all Corporate Units or Treasury Units represented by these certificates for
all purposes under the Corporate Units or Treasury Units and the purchase
contract agreement. Except in the limited circumstances referred to above,
owners of beneficial interests in global security certificates

     - will not be entitled to have such global security certificates or the
       Corporate Units or Treasury Units represented by these certificates
       registered in their names,

     - will not receive or be entitled to receive physical delivery of Corporate
       Unit or Treasury Unit certificates in exchange for beneficial interests
       in global security certificates, and

     - will not be considered to be owners or holders of the global security
       certificates or any Corporate Units or Treasury Units represented by
       these certificates for any purpose under the Corporate Units or Treasury
       Units or the purchase contract agreement.

     All payments on the Corporate Units or Treasury Units represented by the
global security certificates and all transfers and deliveries of related senior
notes, Treasury portfolio, Treasury securities and shares of common stock will
be made to you via the depositary or its nominee, as the case may be.

     Ownership of beneficial interests in the global security certificates will
be limited to participants or persons that may hold beneficial interests through
institutions that have accounts with the depositary or its nominee. Ownership of
beneficial interests in global security certificates will be shown only on, and
the transfer of those ownership interests will be effected only through, records
maintained by the depositary or its nominee, with respect to participants'
interests, or any participant, with respect to interests of persons held by the
participant on their behalf. Procedures for settlement of purchase contracts on
the purchase contract settlement date or upon early settlement will be governed
by arrangements among the depositary, participants and persons that may hold
beneficial interests through participants designed to permit settlement without
the physical movement of certificates. Payments, transfers, deliveries,
exchanges and other matters relating to beneficial interests in global security
certificates may be subject to various policies and procedures adopted by the
depositary from time to time. None of us, the purchase contract agent or

                                       S-51


any agent of ours or the purchase contract agent will have any responsibility or
liability for any aspect of the depositary's or any participant's records
relating to, or for payments made on account of, beneficial interests in global
security certificates, or for maintaining, supervising or reviewing any of the
depositary's records or any participant's records relating to these beneficial
ownership interests.

     Although the depositary has agreed to the foregoing procedures in order to
facilitate transfer of interests in the global security certificates among
participants, the depositary is under no obligation to perform or continue to
perform these procedures, and these procedures may be discontinued at any time.
We will not have any responsibility for the performance by the depositary or its
direct participants or indirect participants under the rules and procedures
governing the depositary.

     The information in this section concerning the depositary and its
book-entry system has been obtained from sources that we believe to be reliable,
but we have not attempted to verify the accuracy of this information.

                                       S-52


 CERTAIN PROVISIONS OF THE PURCHASE CONTRACTS, THE PURCHASE CONTRACT AGREEMENT
                            AND THE PLEDGE AGREEMENT

     This summary summarizes some of the other provisions of the purchase
contract agreement and the pledge agreement. This summary should be read
together with the purchase contract agreement and pledge agreement, forms of
which have been or will be filed and incorporated by reference as exhibits to
the registration statement of which this prospectus supplement and the
accompanying prospectus form a part.

GENERAL

     Except as described in "Description of the Purchase Contracts -- Book-Entry
System," payments on the purchase contracts and senior notes represented by the
Equity Units will be made, purchase contracts (and documents relating to the
Corporate Units, Treasury Units and purchase contracts) will be settled, and
transfers of the Corporate Units and Treasury Units will be registrable, at the
office of the purchase contract agent in the Borough of Manhattan, The City of
New York. In addition, if the Corporate Units and Treasury Units do not remain
in book-entry form, payment on the purchase contracts and the senior notes
represented by the Equity Units may be made, at our option, by check mailed to
the address of the holder entitled to payment as shown on the security register
or by a wire transfer to the account designated by the holder by a prior written
notice.

     Shares of common stock will be delivered on the purchase contract
settlement date (or earlier upon early settlement), or, if the purchase
contracts have terminated, the related pledged securities will be delivered
(potentially after a delay as a result of the imposition of the automatic stay
under the Bankruptcy Code, see "Description of the Purchase
Contracts -- Termination") at the office of the purchase contract agent upon
presentation and surrender of the applicable certificate.

     If you fail to present and surrender the certificate evidencing the
Corporate Units or Treasury Units to the purchase contract agent on or prior to
the purchase contract settlement date, the shares of common stock issuable upon
settlement of the related purchase contract will be registered in the name of
the purchase contract agent. The shares, together with any distributions, will
be held by the purchase contract agent as agent for your benefit until the
certificate is presented and surrendered or you provide satisfactory evidence
that the certificate has been destroyed, lost or stolen, together with any
indemnity that may be required by the purchase contract agent and us.

     If the purchase contracts terminate prior to the purchase contract
settlement date, the related pledged securities are transferred to the purchase
contract agent for distribution to the holders, and a holder fails to present
and surrender the certificate evidencing the holder's Corporate Units or
Treasury Units to the purchase contract agent, the related pledged securities
delivered to the purchase contract agent and payments on the pledged securities
will be held by the purchase contract agent as agent for the benefit of the
holder until the applicable certificate is presented or the holder provides the
evidence and indemnity described above.

     The purchase contract agent will have no obligation to invest or to pay
interest on any amounts held by the purchase contract agent pending payment to
any holder.

     No service charge will be made for any registration of transfer or exchange
of the Corporate Units or Treasury Units, except for any tax or other
governmental charge that may be imposed in connection with a transfer or
exchange.

MODIFICATION

     The purchase contract agreement and the pledge agreement will contain
provisions permitting us and the purchase contract agent, and in the case of the
pledge agreement, the collateral agent, to modify the

                                       S-53


purchase contract agreement or the pledge agreement without the consent of the
holders for any of the following purposes:

     - to evidence the succession of another person to our obligations;

     - to add to the covenants for the benefit of holders or to surrender any of
       our rights or powers under those agreements;

     - to evidence and provide for the acceptance of appointment of a successor
       purchase contract agent or a successor collateral agent or securities
       intermediary;

     - to make provision with respect to the rights of holders pursuant to
       adjustments in the settlement rate due to consolidations, mergers or
       other reorganization events;

     - to cure any ambiguity, to correct any error or to correct or supplement
       any provision that may be inconsistent with any other provision; and

     - to make any other provisions with respect to such matters or questions,
       provided that such action shall not materially adversely affect the
       interest of the holders.

     The purchase contract agreement and the pledge agreement will contain
provisions permitting us and the purchase contract agent, and in the case of the
pledge agreement, the collateral agent, with the consent of the holders of not
less than a majority of the purchase contracts at the time outstanding, to
modify the terms of the purchase contracts, the purchase contract agreement or
the pledge agreement. However, no such modification may, without the consent of
the holder of each outstanding purchase contract affected by the modification,

     - change any payment date,

     - change the amount or type of pledged securities related to the purchase
       contract, impair the right of the holder of any pledged securities to
       receive distributions on the pledged securities or otherwise adversely
       affect the holder's rights in or to the pledged securities,

     - change the place or currency of payment or reduce any contract adjustment
       payments,

     - impair the right to institute suit for the enforcement of the purchase
       contract or payment of any contract adjustment payments,

     - reduce the number of shares of common stock purchasable under the
       purchase contract, increase the price to purchase shares of common stock
       upon settlement of the purchase contract, change the purchase contract
       settlement date or the right to early settlement or otherwise adversely
       affect the holder's rights under the purchase contract, or

     - reduce the above-stated percentage of outstanding purchase contracts the
       consent of the holders of which is required for the modification or
       amendment of the provisions of the purchase contracts, the purchase
       contract agreement or the pledge agreement.

     If any amendment or proposal referred to above would adversely affect only
the Corporate Units or the Treasury Units, then only the affected class of
holders will be entitled to vote on the amendment or proposal, and the amendment
or proposal will not be effective except with the consent of the holders of not
less than a majority of the affected class or of all of the holders of the
affected classes, as applicable.

NO CONSENT TO ASSUMPTION

     Each holder of Equity Units will under the terms of the purchase contract
agreement and the Corporate Units or Treasury Units, as applicable, be deemed
expressly to have withheld any consent to the assumption (i.e., affirmance) by
us or our trustee if we become the subject of a case under the Bankruptcy Code
or other similar state or federal law provision for reorganization or
liquidation.

                                       S-54


CONSOLIDATION, MERGER, SALE OR CONVEYANCE

     We will covenant in the purchase contract agreement that we will not merge
with and into, consolidate with or convert into any other entity or sell,
assign, transfer, lease or convey all or substantially all of our properties and
assets to any person or entity, unless (1) the successor entity is an entity
organized and existing under the laws of the United States of America or a U.S.
state or the District of Columbia and that entity expressly assumes our
obligations under the purchase contracts, the purchase contract agreement, the
pledge agreement and the remarketing agreement and (2) the successor entity is
not, immediately after the merger, consolidation, conversion, sale, assignment,
transfer, lease or conveyance, in default of its payment obligations under the
purchase contracts, the purchase contract agreement, the pledge agreement and
the remarketing agreement or in material default in the performance of any other
covenants under these agreements.

TITLE

     We, the purchase contract agent and the collateral agent may treat the
registered owner of any Corporate Units or Treasury Units as the absolute owner
of the Corporate Units or Treasury Units for the purpose of making payment and
settling the related purchase contracts and for all other purposes.

REPLACEMENT OF EQUITY UNIT CERTIFICATES

     In the event that physical certificates have been issued, any mutilated
Corporate Unit or Treasury Unit certificate will be replaced by us at the
expense of the holder upon surrender of the certificate to the purchase contract
agent. Corporate Unit or Treasury Unit certificates that become destroyed, lost
or stolen will be replaced by us at the expense of the holder upon delivery to
us and the purchase contract agent of evidence of their destruction, loss or
theft satisfactory to us and the purchase contract agent. In the case of a
destroyed, lost or stolen Corporate Unit or Treasury Unit certificate, an
indemnity satisfactory to the purchase contract agent and us may be required at
the expense of the holder of the Corporate Units or Treasury Units evidenced by
the certificate before a replacement will be issued.

     Notwithstanding the foregoing, we will not be obligated to issue any
Corporate Unit or Treasury Unit certificates on or after the business day
immediately preceding the purchase contract settlement date (or after early
settlement) or after the purchase contracts have terminated. The purchase
contract agreement will provide that, in lieu of the delivery of a replacement
Corporate Unit or Treasury Unit certificate following the purchase contract
settlement date, the purchase contract agent, upon delivery of the evidence and
indemnity described above, will deliver the shares of common stock issuable
pursuant to the purchase contracts represented by the Corporate Units or
Treasury Units evidenced by the certificate, or, if the purchase contracts have
terminated prior to the purchase contract settlement date, transfer the pledged
securities represented by the Corporate Units or Treasury Units evidenced by the
certificate.

GOVERNING LAW

     The purchase contract agreement, the pledge agreement and the purchase
contracts will be governed by, and construed in accordance with, the laws of the
State of New York.

INFORMATION CONCERNING THE PURCHASE CONTRACT AGENT

     Bank One Trust Company, N.A. will be the purchase contract agent. The
purchase contract agent will act as the agent for the holders from time to time
of the purchase contracts represented by Corporate Units and Treasury Units from
time to time. The purchase contract agreement will not obligate the purchase
contract agent to exercise any discretionary actions in connection with a
default under the terms of the purchase contracts or the purchase contract
agreement.

     The purchase contract agreement will contain provisions limiting the
liability of the purchase contract agent. The purchase contract agreement will
contain provisions under which the purchase contract agent

                                       S-55


may resign or be replaced. This resignation or replacement would be effective
upon the acceptance of appointment by a successor.

     Bank One Trust Company, N.A. maintains commercial banking relationships
with us.

INFORMATION CONCERNING THE COLLATERAL AGENT

     BNY Midwest Trust Company will be the collateral agent. The collateral
agent will act solely as our agent and will not assume any obligation or
relationship of agency or trust for or with any of the holders of the Corporate
Units or Treasury Units except for the obligations owed by a pledgee of property
to the owner of the property under the pledge agreement and applicable law.

     The pledge agreement will contain provisions limiting the liability of the
collateral agent. The pledge agreement will contain provisions under which the
collateral agent may resign or be replaced. This resignation or replacement
would be effective upon the acceptance of appointment by a successor.

MISCELLANEOUS

     The purchase contract agreement will provide that we will pay all fees and
expenses other than underwriters' expenses (including counsel) related to the
offering of the purchase contracts, the retention of the collateral agent and
the enforcement by the purchase contract agent of the rights of the holders of
the purchase contracts.

     Should you elect to substitute the related pledged securities, create
Treasury Units or recreate Corporate Units, you will be responsible for any fees
or expenses payable in connection with that substitution, as well as any
commissions, fees or other expenses incurred in acquiring the pledged securities
to be substituted, and we will not be responsible for any of those fees or
expenses.

                        DESCRIPTION OF THE SENIOR NOTES

     The following description is a summary of the terms of our senior notes.
The descriptions in this prospectus supplement and the accompanying prospectus
contain a description of certain terms of the senior notes and the indenture but
do not purport to be complete, and reference is hereby made to the indenture,
which is incorporated by reference into the registration statement, and to the
Trust Indenture Act. This summary supplements the description of the senior debt
securities in the accompanying prospectus and, to the extent it is inconsistent,
replaces the description in the accompanying prospectus.

GENERAL

     The senior notes will be issued under an indenture dated as of October 25,
1989 between us and Bank One Trust Company, N.A., successor in interest to The
First National Bank of Chicago, as indenture trustee (the "indenture").

     The senior notes will be senior debt securities that will be our direct,
unsecured obligations and will rank without preference or priority among
themselves and equally with all of our existing and future unsecured senior
indebtedness. The senior notes initially will be issued in an aggregate
principal amount equal to $400,000,000. If the option to purchase additional
senior notes is exercised in full by the underwriters an additional $460,000,000
of the senior notes will be issued.

     We are a holding company that derives all our income from our subsidiaries.
Accordingly, our ability to service our debt, including our obligations under
the senior notes, and other obligations are primarily dependent on the earnings
of our respective subsidiaries and the payment of those earnings to us, in the
form of dividends, loans or advances and through repayment of loans or advances
from us. In addition, any payment of dividends, loans or advances by those
subsidiaries could be subject to statutory or contractual restrictions. Our
subsidiaries have no obligation to pay any amounts due on the senior notes.

     The senior notes will not be subject to a sinking fund provision and will
not be subject to defeasance. Unless a special event redemption occurs prior to
the purchase contract settlement date, the entire principal amount of the senior
notes will mature and become due and payable, together with any accrued and
unpaid interest thereon, on August 16, 2008.

     The indenture trustee will initially be the security registrar and the
paying agent for the senior notes. Senior notes represented by the Corporate
Units will be issued in certificated form, will be in denominations of $25 and
integral multiples of $25, without coupons, and may be transferred or exchanged,
without service charge but upon payment of any taxes or other governmental
charges payable in connection with the transfer or exchange, at the office
described below. Payments on senior notes issued as a global security will be
made to the depositary or a successor depositary. Principal and interest with
respect to certificated notes will be payable, the transfer of the senior notes
will be registrable and senior notes will be exchangeable for notes of a like
aggregate principal amount in denominations of $25 and integral multiples of
$25, at the office or agency maintained by us for this purpose in The City of
New York. We have initially designated the corporate trust office of the
indenture trustee as that office. However, at our option, payment of interest
may be made by check mailed to the address of the holder entitled to payment or
by wire transfer to an account appropriately designated by the holder entitled
to payment.

     The indenture does not contain provisions that afford holders of the senior
notes protection in the event we are involved in a highly leveraged transaction
or other similar transaction that may adversely affect such holders. The
indenture does not limit our ability to issue or incur other debt or issue
preferred stock.

INTEREST

     Each senior note will bear interest initially at the rate of      % per
year from the original issuance date, payable quarterly in arrears on February
16, May 16, August 16 and November 16 of each year,

                                       S-57


commencing August 16, 2003 to the person in whose name the senior note is
registered at the close of business on the first day of the month in which the
interest payment date falls.

     The applicable interest rate on the senior notes may be reset to the reset
rate upon successful remarketing as described above under "Description of the
Purchase Contracts -- Remarketing." The reset rate will become effective on the
reset effective date, which is three business days immediately following a
successful remarketing. If the senior notes are not successfully remarketed, the
interest rate on the senior notes will not be reset.

     The amount of interest payable on the senior notes for any period will be
computed (1) for any full quarterly period on the basis of a 360-day year of
twelve 30-day months and (2) for any period shorter than a full quarterly
period, on the basis of a 30-day month and, for any period less than a month, on
the basis of the actual number of days elapsed per 30-day month. In the event
that any date on which interest is payable on the senior notes is not a business
day, then payment of the interest payable on such date will be made on the next
day that is a business day (and without any interest or other payment in respect
of any such delay), except that, if such business day is in the next calendar
year, then such payment will be made on the preceding business day.

MARKET RESET RATE

     The reset rate will be equal to the rate that is sufficient to allow a
successful remarketing of the senior notes and will be determined by the
remarketing agent. In the case of a reset prior to the third business day
immediately preceding the purchase contract settlement date, which rate would be
effective on the third business day following the date of such successful
remarketing, the reset rate will be the rate determined by the remarketing agent
as the rate the senior notes should bear in order for the senior notes
represented by Corporate Units to have an aggregate market value on the reset
date of approximately (but not less than) 100.50% of the Treasury portfolio
purchase price described under "Description of the Purchase
Contracts -- Remarketing." In the case of a reset on the third business day
immediately preceding the purchase contract settlement date, the reset rate will
be the rate determined by the remarketing agent as the rate the senior notes
should bear in order for each senior note to have an approximate market value of
100.50% of the principal amount of the senior notes, except that the remarketing
on the final remarketing date will be considered successful if the resulting
proceeds (net of fees and commissions, if any) are at least 100% of the
aggregate principal amount of the senior notes.

OPTIONAL REMARKETING

     On or prior to the fifth business day immediately preceding any remarketing
date, but no earlier than the payment date immediately preceding such date,
holders of senior notes that are not represented by Corporate Units may elect to
have their senior notes remarketed in the same manner and at the same price as
senior notes that are represented by Corporate Units by delivering their senior
notes along with a notice of this election to the custodial agent. The custodial
agent will hold the senior notes in an account separate from the collateral
account in which the pledged securities will be held. Holders of senior notes
electing to have their senior notes remarketed will also have the right to
withdraw the election on or prior to the fifth business day immediately
preceding the applicable remarketing date. Holders of Treasury Units that are
also holders of senior notes that are not represented by the Corporate Units may
also participate in any remarketing by recreating Corporate Units from their
Treasury Units at any time on or prior to the second business day immediately
prior to any of the remarketing dates.

PUT OPTION UPON A FAILED FINAL REMARKETING

     If the senior notes have not been successfully remarketed by the purchase
contract settlement date, the holders of senior notes that remain outstanding
and that are not subject to our security interest will have the right to put
their senior notes to us for $25 per senior note, plus accrued and unpaid
interest, on September 30, 2006, which we call the exercise date, by notifying
the indenture trustee on or prior to the fifth business day before the exercise
date.

                                       S-58


EVENTS OF DEFAULT

     In addition to the events of default described in the accompanying
prospectus under "Description of the Debt Securities -- Events of Default," it
shall be an event of default under the senior notes if we fail on the date
payment is due to pay the put price of any senior notes following the exercise
of the put right by any holder of senior notes.

OPTIONAL REDEMPTION -- SPECIAL EVENT

     If a special event, as defined below, occurs and is continuing, prior to
the earlier of (1) the date of a successful remarketing or (2) the purchase
contract settlement date, we may redeem, at our option on any interest payment
date, the senior notes in whole, but not in part, at a price equal to, for each
senior note, the redemption amount, as defined below, plus accrued and unpaid
interest thereon, which we refer collectively to as the redemption price, to the
date of redemption, which we refer to as the "special event redemption date."
The redemption price payable in respect of all senior notes represented by
Corporate Units will be distributed to the collateral agent, which in turn will
apply an amount equal to the redemption amount of such redemption price to
purchase the Treasury portfolio on behalf of the holders of the Corporate Units
and remit the remaining portion (net of fees and expenses, if any), if any, of
such redemption price to the purchase contract agent for payment to the holders
of the Corporate Units. Thereafter, the applicable ownership interest in the
Treasury portfolio will be substituted for the senior notes and will be held by
the collateral agent and pledged to secure the Corporate Unit holders'
obligations to purchase our shares of common stock under the related purchase
contract. Holders of senior notes that are not represented by Corporate Units
will directly receive proceeds from the redemption of the senior notes.

     "Special event" means either a tax event or an accounting event, each as
defined below.

     "Accounting event" means the receipt by the audit committee of our Board of
Directors of a written report in accordance with Statement on Auditing Standards
("SAS") No. 97, "Amendment to SAS No. 50 -- Reports on the Application of
Accounting Principles", from our independent auditors, provided at the request
of management, to the effect that, as a result of a change in accounting rules
after the date of original issuance of the senior notes, we must either (a)
account for the purchase contracts as derivatives under SFAS 133 (or any
successor accounting standard) or (b) account for the Equity Units using the
if-converted method under SFAS 128 (or any successor accounting standard), and
that, in either case, such accounting treatment will cease to apply upon
redemption of the senior notes.

     "Tax event" means the receipt by us of an opinion of counsel, rendered by a
law firm having a recognized national tax practice, to the effect that, as a
result of any amendment to, change in or announced proposed change in the laws
(or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein, or as a result of any
official administrative decision, pronouncement, judicial decision or action
interpreting or applying such laws or regulations, which amendment or change is
effective or which proposed change, pronouncement, action or decision is
announced on or after the date of issuance of senior notes, there is more than
an insubstantial increase in the risk that interest payable by us on the senior
notes is not, or within 90 days of the date of such opinion, will not be,
deductible by us, in whole or in part, for United States federal income tax
purposes.

     "Redemption amount" means, for each senior note, the product of the
principal amount of such senior note and a fraction, the numerator of which is
the Treasury portfolio purchase price, as defined below, and the denominator of
which is the applicable principal amount, as defined below.

     "Treasury portfolio purchase price" means the lowest aggregate ask-side
price quoted by a primary U.S. government securities dealer to the quotation
agent between 9:00 a.m. and 11:00 a.m., New York City time, as defined below, on
the third business day immediately preceding the special event redemption date
for the purchase of the Treasury portfolio described below for settlement on the
special event redemption date.

                                       S-59


     "Applicable principal amount" means the aggregate principal amount of the
senior notes that are represented by Corporate Units on the special event
redemption date.

     "Treasury portfolio" means a portfolio of U.S. Treasury securities (or
principal or interest strips thereof) that mature on or prior to August 15, 2006
in an aggregate amount at maturity equal to the applicable principal amount and
with respect to each scheduled interest payment date on the senior notes that
occurs after the special event redemption date, to and including the purchase
contract settlement date, U.S. Treasury securities (or principal or interest
strips thereof) that mature on or prior to the business day immediately
preceding such scheduled interest payment date in an aggregate amount at
maturity equal to the aggregate interest payment (assuming no reset of the
interest rate) that would be due on the applicable principal amount of the
senior notes on such date.

     "Quotation agent" means any primary U.S. government securities dealer
selected by us.

AGREEMENT BY PURCHASERS TO CERTAIN TAX TREATMENT

     Each senior note will provide that, by acceptance of the senior note or a
beneficial interest therein, you intend that the senior note constitutes debt
and you agree to treat it as debt for United States federal, state and local tax
purposes.

BOOK-ENTRY SYSTEM

     Senior notes that are released from the pledge following substitution or
settlement of the purchase contracts will be issued in the form of one or more
global certificates, which are referred to as global securities, registered in
the name of the depositary or its nominee. Except under the limited
circumstances described below or except upon recreation of Corporate Units,
senior notes represented by the global securities will not be exchangeable for,
and will not otherwise be issuable as, senior notes in certificated form. The
global securities described above may not be transferred except by the
depositary to a nominee of the depositary or by a nominee of the depositary to
the depositary or another nominee of the depositary or to a successor depositary
or its nominee.

     The laws of some jurisdictions may require that some purchasers of
securities take physical delivery of the securities in certificated form. These
laws may impair the ability to transfer beneficial interests in such a global
security.

     Except as provided below, owners of beneficial interests in such a global
security will not be entitled to receive physical delivery of senior notes in
certificated form and will not be considered the holders (as defined in the
indenture) thereof for any purpose under the indenture, and no global security
representing senior notes shall be exchangeable, except for another global
security of like denomination and tenor to be registered in the name of the
depositary or its nominee or a successor depositary or its nominee. Accordingly,
each beneficial owner must rely on the procedures of the depositary or if such
person is not a participant, on the procedures of the participant through which
such person owns its interest to exercise any rights of a holder under the
indenture.

     In the event that

     - the depositary notifies us that it is unwilling or unable to continue as
       a depositary for the global security certificates and no successor
       depositary has been appointed within 90 days after this notice,

     - an event of default occurs and is continuing with respect to the senior
       notes, or

     - we determine in our sole discretion that we will no longer have senior
       notes represented by global securities,

certificates for the senior notes will be printed and delivered in exchange for
beneficial interests in the global security certificates. Any global note that
is exchangeable pursuant to the preceding sentence shall be exchangeable for
senior note certificates registered in the names directed by the depositary. We
expect that these instructions will be based upon directions received by the
depositary from its participants with respect to ownership of beneficial
interests in the global security certificates.

                                       S-60


                        UNITED STATES FEDERAL INCOME TAX

     The following is a discussion of the principal U.S. federal income tax
consequences of the purchase, ownership and disposition of Equity Units and the
senior notes, Treasury securities (including an applicable ownership interest in
the Treasury portfolio) and purchase contracts that are or may be the components
of Equity Units, and shares of our common stock acquired through a purchase
contract. This discussion is addressed only to holders of Equity Units who
purchase Equity Units in the initial offering at their original offering price
and hold the Equity Units, senior notes, Treasury securities, purchase contracts
and shares of our common stock as capital assets. This discussion is based upon
the Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations
and proposed Treasury regulations issued under the Code, Internal Revenue
Service ("IRS") rulings and pronouncements and judicial decisions now in effect,
all of which may change, possibly with retroactive effect.

     This discussion does not address all aspects of U.S. federal income
taxation that may be relevant to holders in light of their particular
circumstances, such as holders to whom special tax treatment applies, including
(1) banks, regulated investment companies, real estate investment trusts,
insurance companies, dealers in securities or currencies or tax-exempt
organizations, (2) persons holding Equity Units, senior notes or shares of our
common stock as part of a straddle, hedge, conversion transaction or other
integrated investment, (3) U.S. holders (as defined below) whose functional
currency is not the U.S. dollar, or (4) traders in securities that elect to use
a mark to market method of accounting for their securities holdings. In
addition, this discussion does not address alternative minimum taxes or state,
local or foreign taxes.

     No statutory, administrative or judicial authority directly addresses the
treatment of Equity Units or instruments similar to Equity Units for U.S.
federal income tax purposes. As a result, no assurance can be given that the IRS
or a court will agree with the tax consequences described in this discussion. A
differing treatment from that assumed below could adversely affect the amount,
timing and character of income, gain or loss in respect of an investment in the
Equity Units. Prospective investors are urged to consult their own tax advisors
with respect to the U.S. federal income tax consequences of the purchase,
ownership and disposition of Equity Units, senior notes, Treasury securities and
shares of our common stock acquired under a purchase contract in light of their
own particular circumstances, as well as the effect of any state, local or
foreign tax laws.

CONSEQUENCES TO U.S. HOLDERS

     The following is a discussion of U.S. federal income tax considerations
relevant to a "U.S. holder" of Equity Units. For purposes of this discussion,
the term U.S. holder means an individual who is a citizen or resident of the
United States, a U.S. domestic corporation or any other entity or person
generally subject to U.S. federal income tax on a net income basis.

EQUITY UNITS

     OWNERSHIP OF SENIOR NOTES OR TREASURY SECURITIES.  For U.S. federal income
tax purposes, a U.S. holder will be treated as owning the senior notes (or
Treasury securities) constituting a part of the holder's Equity Units. We, under
the terms of the Equity Units, and each U.S. holder, by acquiring Equity Units,
agree to treat the senior notes (or Treasury securities) constituting a part of
the Equity Units as owned by that U.S. holder for all tax purposes, and the
remainder of this summary assumes this treatment. The U.S. federal income tax
consequences of owning the senior notes or Treasury securities are discussed
below under "Senior Notes" and "Treasury Securities Purchased in Connection with
Equity Units."

     ALLOCATION OF PURCHASE PRICE.  A U.S. holder's acquisition of a Corporate
Unit will be treated as an acquisition of the senior note and the purchase
contract constituting the Corporate Unit for U.S. federal income tax purposes
and, by purchasing a Corporate Unit, you will be deemed to have agreed to that
treatment. The remainder of this discussion assumes that the acquisition of a
Corporate Unit will be so treated. The purchase price of a Corporate Unit will
be allocated between the senior note and the purchase contract constituting the
Corporate Unit, in proportion to their respective fair market values at the time
of

                                       S-61


purchase. This allocation will establish the U.S. holder's initial tax basis in
the senior note and the purchase contract. Upon issuance of the Corporate Units,
we expect to report the fair market value of each senior note as $  and the fair
market value of each purchase contract as $     . This position will be binding
on each U.S. holder unless a U.S. holder explicitly discloses a contrary
position on a statement attached to that U.S. holder's timely filed U.S. federal
income tax returns for the taxable year in which that U.S. holder acquires a
Corporate Unit, but this position will not be binding on the IRS. Thus, absent
disclosure of that kind, a U.S. holder should allocate the purchase price for a
Corporate Unit in accordance with the values reported by us. The remainder of
this discussion assumes that this allocation of the purchase price of a
Corporate Unit will be respected for U.S. federal income tax purposes.

     SALES, EXCHANGES OR OTHER TAXABLE DISPOSITIONS OF EQUITY UNITS.  If a U.S.
holder sells, exchanges or otherwise disposes of Equity Units in a taxable
disposition, the U.S. holder will be treated as having sold, exchanged or
disposed of each of the purchase contract and the senior note or Treasury
securities that constitute the Equity Units. The proceeds realized on this
disposition will be allocated between the purchase contract and the senior note
or Treasury securities in proportion to their respective fair market values at
the time of disposition. As a result, as to each of the purchase contract and
the senior note or Treasury securities, a U.S. holder generally will recognize
gain or loss equal to the difference between the portion of the proceeds
received by the U.S. holder that is allocable to the purchase contract and the
senior note or Treasury securities, respectively, and the U.S. holder's adjusted
tax basis in the purchase contract and the senior note or Treasury securities,
respectively, except that amounts received by a taxpayer who uses a cash method
of tax accounting with respect to accrued but unpaid interest on Treasury
securities will be treated as ordinary interest income to the extent not
previously taken into income.

     In the case of the purchase contract and the Treasury securities, the gain
or loss generally will be capital gain or loss. The gain or loss generally will
be long-term capital gain or loss if the U.S. holder held the Equity Unit or, in
the case of the Treasury securities, the Treasury security for more than one
year immediately before the disposition. Long-term capital gains of individuals
are eligible for reduced rates of taxation. The deductibility of capital losses
is subject to limitations. We summarize the rules governing the determination of
the character of gain or loss on the disposition of a senior note under "Senior
notes -- Sales, exchanges, remarketing or other taxable dispositions of senior
notes." Because gain or loss on disposition of a senior note may be treated as
ordinary income or loss, disposition of a Corporate Unit consisting of a
purchase contract and a senior note may give rise to capital gain or loss on the
purchase contract and ordinary income or loss on the senior note, which must be
reported separately for U.S. federal income tax purposes.

     If the sale, exchange or other disposition of an Equity Unit occurs when
the purchase contract has a negative value, a U.S. holder should be considered
to have received additional consideration for the senior note or Treasury
securities in an amount equal to that negative value and to have paid that
amount to be released from the U.S. holder's obligations under the related
purchase contract. Because, as discussed below, any gain on the disposition of a
senior note before the interest rate reset or final remarketing date (if
earlier) generally will be treated as ordinary interest income for U.S. federal
income tax purposes, the ability to off-set that interest income with a loss on
the purchase contract may be limited. U.S. holders should consult their tax
advisors regarding a disposition of an Equity Unit at a time when the purchase
contract has a negative value.

SENIOR NOTES

     ORIGINAL ISSUE DISCOUNT.  Because of the manner in which the interest rates
on the senior notes are reset, we intend to take the position that the senior
notes are contingent payment debt instruments subject to the "noncontingent bond
method" for accruing original issue discount, as established in the applicable
Treasury Regulations and, under the senior indenture, each holder agrees to
treat the senior notes as indebtedness subject to the regulations governing
contingent payment debt instruments. The remainder of this disclosure assumes
that the senior notes are contingent payment debt instruments for U.S. federal
income tax purposes.

                                       S-62


     As discussed more fully below, the effects of applying this method will be
(1) to require each U.S. holder, regardless of the holder's usual method of tax
accounting, to use an accrual method with respect to the interest income on
senior notes, (2) to require each U.S. holder to accrue interest income in
excess of interest payments actually received for all accrual periods through
May 16, 2006 and possibly for accrual periods after that date, and (3) generally
to result in ordinary, rather than capital, treatment of any gain or loss on the
sale, exchange or other disposition of senior notes before the interest rate is
reset or the final remarketing date (if earlier). (See "Sales, exchanges,
remarketing or other taxable dispositions of senior notes" below).

     A U.S. holder will be required to accrue original issue discount on a
constant yield to maturity basis based on the "comparable yield" of the senior
notes. The comparable yield of the senior notes generally will be the rate at
which we would issue a fixed rate noncontingent debt instrument with terms and
conditions similar to the senior notes. We have determined that the comparable
yield on the senior notes is      %.

     The amount of original issue discount on a senior note for each accrual
period will be determined by multiplying the comparable yield of the senior
note, adjusted for the length of the accrual period, by the senior note's
adjusted issue price at the beginning of the accrual period. Based on the
allocation of the purchase price of each Equity Unit described above under
"-- Equity Units -- Allocation of purchase price," the adjusted issue price of
each senior note, per $25 of principal amount, at the beginning of the first
accrual period will be $       , and the adjusted issue price of each senior
note at the beginning of each subsequent accrual period will be equal to
$       , increased by any original issue discount previously accrued by the
U.S. holder on the senior note and decreased by the amount of payments received
(as described below) on the senior note through that date. The amount of
original issue discount so determined will then be allocated on a ratable basis
to each day in the accrual period that the U.S. holder holds the senior note.

     If, after the date on which the interest rate on the senior notes is reset
(or the final remarketing date, if earlier), the remaining amounts of principal
and interest payable differ from the payments stated on the applicable projected
payment schedule, as described below, negative or positive adjustments
reflecting this difference should generally be taken into account by the U.S.
holder as adjustments to interest income in a reasonable manner over the period
to which they relate.

     A projected payment schedule for a senior note subject to the noncontingent
bond method must include stated interest and principal payments on the senior
note and additional projected payments on the senior note in amounts such that
all projected payments produce a yield to maturity on the senior note equal to
the senior note's comparable yield, computed by taking into account the issue
price of the senior note. We have determined that the projected payments for the
senior notes, per $25 of principal amount, are $          for the quarter ending
on August 16, 2003, $          for each quarter ending thereafter on or before
May 16, 2006 and $          for each quarter ending after May 16, 2006 and that
the projected payment for the senior notes, per $25 of principal amount, at the
maturity date is $          , which includes the stated principal amount of the
senior notes as well as the final projected interest payment.

     A U.S. holder is generally bound by the comparable yield and projected
payment schedule provided by us under the terms of the Equity Units unless
either is unreasonable. If a U.S. holder of senior notes does not use this
comparable yield and projected payment schedule to determine interest accruals,
such U.S. holder must apply the foregoing rules using its own comparable yield
and projected payment schedule. A U.S. holder that uses its own comparable yield
and projected payment schedule must explicitly disclose this fact and the reason
why it has used its own comparable yield and payment schedule. In general, this
disclosure must be made on a statement attached to the timely filed United
States federal income tax return of the U.S. holder for the taxable year that
includes the date of its acquisition of the Equity Units.

     We supply the comparable yield and projected payment schedules solely for
computing income under the noncontingent bond method for U.S. federal income tax
purposes. These schedules do not constitute projections or representations as to
the amounts that a U.S. holder will actually receive as a result of owning
senior notes or Equity Units.

                                       S-63


     TAX BASIS IN SENIOR NOTES.  A U.S. holder's tax basis in a senior note will
be equal to the portion of the purchase price for a Corporate Unit allocated to
the senior notes as described above under "-- Equity Units -- Allocation of
purchase price," increased by the amount of original issue discount included in
income with respect to the senior note and decreased by the amount of payments
received with respect to the senior note through the computation date.

     SALES, EXCHANGES, REMARKETING OR OTHER TAXABLE DISPOSITIONS OF SENIOR
NOTES.  A U.S. holder will recognize gain or loss on a disposition of senior
notes, including a redemption for cash or upon the remarketing of the senior
notes, in an amount equal to the difference between the amount realized by the
U.S. holder on the disposition of the senior notes and the U.S. holder's
adjusted tax basis in the senior notes. Selling expenses incurred by the U.S.
holder, including the remarketing fee, will reduce the amount of gain or
increase the amount of loss recognized by the U.S. holder upon a disposition of
senior notes. Gain recognized on the disposition of a senior note before the
date on which the interest rate on the senior notes is reset (or the final
remarketing date, if earlier) will be treated as ordinary interest income. Loss
recognized on the disposition of a senior note before the interest rate reset
date (or the final remarketing date, if earlier) will be treated as ordinary
loss to the extent of the U.S. holder's prior inclusions of original issue
discount on the senior note reduced by coupon payments received. Any loss in
excess of this amount will be treated as a capital loss. In general, gain
recognized on the disposition of a senior note on or after the interest rate
reset date (or the final remarketing date, if earlier) will be ordinary interest
income to the extent attributable to the excess, if any, of the total remaining
principal and interest payments due on the senior note over the total remaining
payments stated on the projected payment schedule for the senior note. Any gain
recognized in excess of this amount and any loss recognized on a disposition of
this kind will generally be treated as a capital gain or loss. Long-term capital
gains of individuals are eligible for reduced rates of taxation. There are
limitations on deductibility of capital losses.

PURCHASE CONTRACTS

     ACQUISITION OF OUR COMMON STOCK UNDER A PURCHASE CONTRACT.  A U.S. holder
generally will not recognize gain or loss on the purchase of our common stock
under a purchase contract, except with respect to any cash paid to a U.S. holder
in lieu of a fractional share of our common stock, which should be treated as
paid in exchange for the fractional share. A U.S. holder's aggregate initial tax
basis in our common stock received under a purchase contract should generally
equal the $25 payment made to us by the U.S. holder in respect of the purchase
contract on the purchase contract settlement date, plus the properly allocable
portion of the U.S. holder's adjusted tax basis, if any, in the purchase
contract as described under "-- Equity Units -- Allocation of purchase price,"
less the portion of the purchase price and adjusted tax basis allocable to any
fractional shares. The holding period for our common stock received under a
purchase contract will commence on the day of the acquisition of the common
stock.

     EARLY SETTLEMENT OF A PURCHASE CONTRACT.  The purchase of our common stock
on early settlement of a purchase contract will be taxed as described above. A
U.S. holder of Equity Units will not recognize gain or loss on the return of the
senior notes or Treasury securities that are a component of the U.S. holder's
Equity Units upon early settlement of a purchase contract and will have the same
adjusted tax basis and holding period in the senior notes or Treasury securities
as before the early settlement.

     TERMINATION OF A PURCHASE CONTRACT.  If a purchase contract terminates, a
U.S. holder of Equity Units will recognize a loss equal to the U.S. holder's
adjusted tax basis, if any, in the purchase contract at the time of the
termination. Any loss of this kind will be a capital loss. There are limitations
on deductibility of capital losses. A U.S. holder will not recognize gain or
loss on the return of the senior notes or Treasury securities that are
represented by a U.S. holder's Equity Units upon termination of the purchase
contract, and the U.S. holder will have the same adjusted tax basis and holding
period in the senior notes or Treasury securities as before the termination.

     ADJUSTMENT TO SETTLEMENT RATE.  A U.S. holder of Equity Units might be
treated as receiving a constructive dividend distribution from us if (1) the
settlement rate is adjusted and as a result of the adjustment the U.S. holder's
proportionate interest in our assets or earnings and profits is increased and

                                       S-64


(2) the adjustment is not made under a bona fide, reasonable anti-dilution
formula. An adjustment in the settlement rate would not be considered made under
a formula of this kind if the adjustment were made to compensate a U.S. holder
for certain taxable distributions with respect to the common stock. Thus, under
certain circumstances, an increase in the settlement rate might give rise to a
taxable dividend to a U.S. holder of Equity Units even though the U.S. holder
would not receive any cash related to the increase in the settlement rate.

     CONTRACT ADJUSTMENT PAYMENTS AND DEFERRED CONTRACT ADJUSTMENT
PAYMENTS.  There is no direct authority addressing the treatment, under current
law, of the contract adjustment payments or deferred contract adjustment
payments, and such treatment is therefore unclear. Contract adjustment payments
and deferred contract adjustment payments may constitute taxable ordinary income
to a U.S. holder when received or accrued, in accordance with the U.S. holder's
regular method of tax accounting. We intend to file information returns that
report contract adjustment payments and deferred contract adjustment payments as
taxable ordinary income to U.S. holders. U.S. holders should consult their tax
advisors concerning the treatment of contract adjustment payments and deferred
contract adjustment payments, including the possibility that any contract
adjustment payments or deferred contract adjustment payments may be treated as a
loan, purchase price adjustment, rebate or payment analogous to an option
premium, rather than being includible in income on a current basis.

     The treatment of contract adjustment payments and deferred contract
adjustment payments could affect a U.S. holder's adjusted tax basis in a
purchase contract or shares of our common stock received under a purchase
contract or the amount realized by a U.S. holder upon the sale of disposition of
an Equity Unit or the termination of a purchase contract. In particular,

     - amounts received on sale or disposition of an Equity Unit or on
       termination of a purchase contract with respect to any accrued but unpaid
       contract adjustment payments or deferred contract adjustment payments
       that have not been included in a U.S. holder's income may be treated as
       ordinary income;

     - any contract adjustment payments or deferred contract adjustment payments
       that have been included in a U.S. holder's income, but that have not been
       paid to the U.S. holder, should increase the U.S. holder's adjusted tax
       basis in the purchase contract; and

     - any contract adjustment payments or deferred contract adjustment payments
       that have been paid to a U.S. holder, but that have not been included in
       the U.S. holder's income, should either reduce the U.S. holder's adjusted
       tax basis in the purchase contract or result in an increase in the amount
       realized on termination or disposition of the purchase contract.

COMMON STOCK

     Any taxable distribution on our common stock paid by us out of our current
or accumulated earnings and profits as determined for U.S. federal income tax
purposes will constitute a dividend and will be includible in income by a U.S.
holder when received. Any dividend of this kind will be eligible for the
dividends received deduction generally allowed to U.S. corporations in respect
of dividends received from other U.S. corporations if the U.S. holder is an
otherwise qualifying corporate holder that meets the holding period and other
requirements for the dividends received deduction. Recently enacted legislation
reduces the effective tax rate on dividends received by individuals through
December 31, 2008. Dividends received by individuals after December 31, 2008
will not benefit from this reduction in tax rates. Upon a disposition of our
common stock, a U.S. holder will recognize capital gain or loss in an amount
equal to the difference between the amount realized and the U.S. holder's
adjusted tax basis in our common stock as described under "Purchase
contracts -- Acquisition of our common stock under a purchase contract."
Long-term capital gains of individuals are eligible for reduced rates of
taxation.

CREATION OF TREASURY UNITS AND RECREATION OF CORPORATE UNITS

     SUBSTITUTION OF TREASURY SECURITIES TO CREATE TREASURY UNITS.  A U.S.
holder of Corporate Units who delivers Treasury securities to the collateral
agent in substitution for senior notes or other pledged securities generally
will not recognize gain or loss upon the delivery of the Treasury securities or
the release of the senior notes or other pledged securities to the U.S. holder.
The U.S. holder will continue to take into account items of income otherwise
includible or deductions otherwise deductible by the U.S. holder with respect to
the Treasury securities and senior notes or other pledged securities, and the
purchase contract will not be affected by the delivery and release. For a
discussion of the tax consequences of holding Treasury securities, see "Treasury
Securities Purchased in Connection with Equity Units," below.

     SUBSTITUTION OF SENIOR NOTES TO RECREATE CORPORATE UNITS.  A U.S. holder of
Treasury Units who delivers senior notes to the collateral agent in substitution
for pledged Treasury securities generally will not recognize gain or loss upon
the delivery of the senior notes or the release of the pledged Treasury
securities to the U.S. holder. The U.S. holder will continue to take into
account items of income otherwise includible or deductions otherwise deductible
by the holder with respect to the pledged Treasury securities and the senior
notes. The U.S. holder's tax basis in the senior notes, the pledged Treasury
securities and the purchase contract will not be affected by the delivery and
release. U.S. holders should consult their own advisors concerning the tax
consequences of purchasing, owning and disposing of the Treasury securities so
released to them.

TREASURY SECURITIES PURCHASED IN CONNECTION WITH EQUITY UNITS

     A U.S. holder's initial basis in the Treasury securities purchased in
connection with an Equity Unit will be equal to the amount paid for the Treasury
securities.

     In general, a U.S. holder will be required for U.S. federal income tax
purposes to recognize original issue discount on Treasury securities (other than
short-term Treasury securities, as defined below), on a constant yield basis,
regardless of the U.S. holder's method of tax accounting, and to recognize
acquisition discount on Treasury securities when it is paid or accrues generally
in accordance with the U.S. holder's normal method of tax accounting. U.S.
holders should consult their own tax advisors concerning the tax consequences of
purchasing, owning and disposing of the Treasury securities delivered to the
collateral agent.

     For purposes of this discussion, a short-term Treasury security is any
Treasury security with a maturity of one year or less from the date of its issue
(or in the case of a Treasury strip, from the date of its purchase by the U.S.
holder). If a U.S. holder is on the cash method of accounting, it will generally
not include income on short-term Treasury securities until payment is received
on them. If a U.S. holder is on the accrual method of accounting, it will be
required to include acquisition discount in income over the remaining term of
the short-term Treasury securities and will increase its basis in the short-term
Treasury securities by the amount of acquisition discount included in income.

     A U.S. holder will also be required, for U.S. federal income tax purposes,
to include in income any earnings on the investment by the collateral agent of
the cash proceeds paid on the maturity of the Treasury securities.

BACKUP WITHHOLDING TAX AND INFORMATION REPORTING

     Unless a U.S. holder is an exempt recipient, such as a corporation,
payments under Equity Units, senior notes, purchase contracts, Treasury
securities or our common stock, the proceeds received with respect to a
fractional share of our common stock upon the settlement of a purchase
contracts, and the proceeds received from the sale of Equity Units, senior
notes, purchase contract, Treasury securities or our common stock, will be
subject to information reporting and may also be subject to U.S. federal backup
withholding tax if the U.S. holder fails to supply accurate taxpayer
identification numbers or otherwise fails to comply with applicable U.S.
information reporting or certification requirements. Any amounts withheld under
the backup withholding rules will be allowed as a credit against a U.S. holder's
U.S. federal income tax liability provided the U.S. holder provides the required
information to the IRS.

                                       S-66


CONSEQUENCES TO NON-U.S. HOLDERS

     The following discussion is a summary of the principal U.S. federal income
tax consequences resulting from the purchase, acquisition and ownership of
Equity Units by "non-U.S. holders." For purposes of this discussion, a "non-U.S.
holder" is a holder of an Equity Unit that is not a U.S. person. A "U.S. person"
is a citizen or resident of the United States, a corporation, partnership or
other entity created or organized in or under the laws of the United States or
any political subdivision of the United States, an estate to whom income U.S.
federal income taxation applies regardless of its source or a trust if (a) a
U.S. court is able to exercise primary supervision over the trust's
administration and (b) one or more U.S. persons have the authority to control
all of the trust's substantial decisions.

     CURRENT PAYMENTS, DIVIDENDS AND CERTAIN EARNINGS.  The payment of interest,
including gain on the disposition of a senior note that is treated as interest,
amounts attributable to original issue discount on the senior notes or Treasury
securities, and any earnings on the investment by the collateral agent of the
cash proceeds paid on the maturity of the Treasury securities, to a non-U.S.
holder will not be subject to U.S. federal withholding tax if: (1) in the case
of senior notes, the non-U.S. holder does not actually or constructively own 10%
or more of the total voting power of all of our voting stock and is not a
controlled foreign corporation that is related to us within the meaning of the
Code, and (2) the beneficial owner of the senior note or Treasury securities
provides a statement signed under penalties of perjury that includes its name
and address and certifies that it is a non-U.S. holder in compliance with
applicable requirements or satisfies certain documentary evidence requirements
for establishing that it is a non-U.S. holder. If the foregoing exceptions do
not apply, payments on the senior notes or Treasury securities with an original
term longer than 183 days may be subject to gross withholding at the rate of 30%
or such lower rate as may be available to a non-U.S. holder under an applicable
treaty.

     Dividend payments to non-U.S. holders in respect of our common stock will
be subject to U.S. withholding tax at a rate of 30% or such lower rate as may be
available to a non-U.S. holder under an applicable treaty.

     CONTRACT ADJUSTMENT PAYMENTS.  Although the U.S. federal income tax
treatment of contract adjustment payments and deferred contract adjustment
payments is unclear, we intend to take the position that contract adjustment
payments and deferred contract adjustment payments paid to a non-U.S. holder
constitute fixed or determinable annual or periodic income, subject to
withholding tax at a rate of 30%. A non-U.S. holder should, however, consult its
tax advisor concerning the treatment of contract adjustment payments and
deferred contract adjustment payments, including the possibility that any
contract adjustment payments and deferred contract adjustment payments may be
treated as a loan, purchase price adjustment, rebate or payment analogous to an
option premium.

     GAIN OR LOSS ON DISPOSITION.  A non-U.S. holder will not be subject to U.S.
federal income tax on gain (other than gain on the disposition of a senior note
that is treated as interest) realized on the sale, exchange, maturity or
redemption of either a Corporate Unit, a Treasury Unit, a senior note, a
purchase contract, any Treasury securities, or any shares of our common stock
unless (1) the gain is effectively connected with the conduct by the holder of a
trade or business in the United States or (2) in the case of gain realized by an
individual holder, the holder is present in the United States for 183 days or
more in the taxable year of the sale and either (A) the gain or income is
attributable to an office or other fixed place of business maintained in the
United States by the holder or (B) the holder has a tax home in the United
States.

     INFORMATION REPORTING AND BACKUP WITHHOLDING.  In general, backup
withholding and information reporting will not apply to payments made by us or
our paying agents, in their capacities as our paying agents, to a non-U.S.
holder as long as the income associated with the payments is otherwise exempt
from U.S. federal income tax and the holder has provided the required
certification that it is a non-U.S. holder, unless either we or our paying agent
has actual knowledge that the holder is a U.S. person.

                                  UNDERWRITING

     Citigroup Global Markets Inc., Goldman, Sachs & Co. and Merrill Lynch,
Pierce, Fenner & Smith Incorporated are acting as joint bookrunning managers of
this offering, and are acting as representatives of the underwriters named
below.

     Subject to the terms and conditions stated in the underwriting agreement
dated the date of this prospectus supplement, each underwriter named below has
agreed to purchase, and we have agreed to sell to that underwriter, the number
of Corporate Units set forth opposite the underwriter's name.



                                                                 NUMBER OF

  Total.....................................................    16,000,000
                                                                ==========


     The underwriting agreement provides that the obligations of the
underwriters to purchase the Corporate Units included in this offering are
subject to approval of legal matters by counsel and to other conditions. The
underwriters are obligated to purchase all the Corporate Units (other than those
covered by the option to purchase additional Corporate Units described below) if
they purchase any of Corporate Units.

     If the underwriters sell more purchase contracts and senior notes
represented by Corporate Units than the total number set forth in the table
above, the underwriters have an option to buy purchase contracts and senior
notes represented by up to an additional 2,400,000 Corporate Units from us to
cover such sales. They may purchase those additional purchase contracts within a
13 day period beginning on the date of first issuance of the Corporate Units. If
any purchase contracts and senior notes represented by Corporate Units are
purchased pursuant to this option, the underwriters will severally purchase
Corporate Units in approximately the same proportion as set forth above.

     Corporate Units sold by the underwriters to the public will initially be
offered at the initial public offering price set forth on the cover of this
prospectus supplement. Any Corporate Units sold by the underwriters to
securities dealers may be sold at a discount from the initial public offering
price of up to $     per Corporate Unit. Any such securities dealers may resell
any Corporate Units purchased from the underwriters to certain other brokers or
dealers at a discount from the initial public offering price of up to $     per
Corporate Unit. If all the Corporate Units are not sold at the initial offering
price, the underwriters may change the offering price and the other selling
terms.

     The purchase contracts and the senior notes are new issues of securities
with no established trading market. We have been advised by the underwriters
that the underwriters intend to make a market in the Corporate Units but are not
obligated to do so and may discontinue market making at any time without notice.
No assurance can be given as to the liquidity of the trading market for the
Corporate Units.

     We and our executive officers and directors have agreed that, for a period
of 90 days from the date of this prospectus supplement, we and they will not,
without the prior written consent of the underwriters, dispose of, hedge or file
with the SEC a registration statement under the Securities Act with respect to,
any equity units, any shares of our common stock or any securities convertible
into or exchangeable for our common stock. The foregoing sentence shall not
apply to (A) the equity units in this offering and the shares of common stock to
be issued to the underwriters in our concurrent common stock offering, and
(B)(i) the exercise of options outstanding as of the date of this prospectus
supplement, (ii) dispositions of

                                       S-68


common stock by such executive officers or directors by gift to members of such
directors' or officers' immediate families or to trusts established for the
benefit of members of such directors' or officers' immediate families (provided
that any such recipient agrees in writing as a condition to receiving such
common stock to be bound by the foregoing restrictions), (iii) dispositions of
common stock by such executive officers or directors by bona fide gift to
charitable organizations, (iv) our issuance of stock options and restricted
stock to employees, provided that such options are not exercisable, and such
restricted stock grants do not vest, before the expiration of the 90-day period,
(v) our issuance and sale of common stock pursuant to any employee stock option
plan, stock ownership plan or dividend reinvestment plan in effect on the date
of this prospectus supplement and (vi) our issuance of common stock issuable
upon the conversion of securities or the exercise of warrants outstanding on the
date of this prospectus supplement.

     The underwriters in their sole discretion may release any of the securities
subject to these lock-up agreements at any time without notice.

     Each underwriter has represented, warranted and agreed that:

     - it has not offered or sold and, prior to the expiry of a period of six
       months from the closing date, will not offer or sell any Corporate Units
       included in this offering 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 have not
       resulted and will not result in an offer to the public in the United
       Kingdom within the meaning of the Public Offers of Securities Regulations
       1995;

     - it has only communicated and caused to be communicated and will only
       communicate or cause to be communicated any invitation or inducement to
       engage in investment activity (within the meaning of section 21 of the
       Financial Services and Markets Act 2000 ("FSMA")) received by it in
       connection with the issue or sale of any Corporate Units included in this
       offering in circumstances in which section 21(1) of the FSMA does not
       apply to us;

     - it has complied and will comply with all applicable provisions of the
       FSMA with respect to anything done by it in relation to the Corporate
       Units included in this offering in, from or otherwise involving the
       United Kingdom; and

     - the offer in The Netherlands of the Corporate Units included in this
       offering is exclusively limited to persons who trade or invest in
       securities in the conduct of a profession or business (which include
       banks, stockbrokers, insurance companies, pension funds, other
       institutional investors and finance companies and treasury departments of
       large enterprises).

     The following table shows the underwriting discounts and commissions that
we are to pay to the underwriters in connection with this offering. These
amounts are shown assuming both no exercise and full exercise of the
underwriters' option to purchase additional Corporate Units.



                                                                     PAID BY CHUBB

Total.......................................................   $              $


     In connection with this offering, the underwriters may purchase and sell
the Corporate Units in the open market. These transactions may include short
sales, syndicate covering transactions and stabilizing transactions. Short sales
involve syndicate sales in excess of the number of Corporate Units to be
purchased by the underwriters in this offering, which creates a syndicate short
position. "Covered" short sales are sales made in an amount up to the number of
Corporate Units represented by the underwriters' option to purchase additional
Corporate Units. In determining the source of Corporate Units to close out the
covered syndicate short position, the underwriters will consider, among other
things, the price of Corporate Units available for purchase in the open market
as compared to the price at which they may purchase Corporate Units through the
option to purchase additional Corporate Units. Transactions to close

                                       S-69


out the covered syndicate short involve either purchases of Corporate Units in
the open market after the distribution has been completed or the exercise of the
option to purchase additional Corporate Units. The underwriters may also make
"naked" short sales of Corporate Units in excess of the over-allotment option.
The underwriters must close out any naked short position by purchasing Corporate
Units in the open market. A naked short position is more likely to be created if
the underwriters are concerned that there may be downward pressure on the price
of the Corporate Units in the open market after pricing that will adversely
affect investors who purchase in the offering. Stabilizing transactions consist
of bids for or purchases of Corporate Units in the open market while the
offering is in progress.

     The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when the
underwriters repurchase Corporate Units originally sold by that syndicate member
in order to cover syndicate short positions or make stabilizing purchases.

     Any of these activities may have the effect of preventing or retarding a
decline in the market price of the Corporate Units. They may also cause the
price of the Corporate Units to be higher than the price that would otherwise
exist in the open market in the absence of these transactions. The underwriters
may conduct these transactions on the New York Stock Exchange or in the
over-the-counter market, or otherwise. If the underwriters commence any of these
transactions, they may discontinue them at any time.

     We estimate that our portion of the total expenses of this offering will be
approximately $          .

     The underwriters and their affiliates have performed investment banking,
commercial lending and advisory services for us from time to time for which they
have received customary fees and expenses. The underwriters may, from time to
time, engage in transactions with and perform services for us in the ordinary
course of their business.

     This prospectus supplement and the accompanying prospectus, as amended or
supplemented, may be used in connection with the early settlement of the
purchase contracts and the remarketing of the senior notes.

     A prospectus in electronic format may be made available on the websites
maintained by one or more of the underwriters. The underwriters may agree to
allocate a number of Corporate Units for sale to their online brokerage account
holders. The underwriters have advised us that they will allocate Corporate
Units for Internet distributions on the same basis as other allocations. In
addition, Corporate Units may be sold by the underwriters to securities dealers
who resell Corporate Units to online brokerage account holders.

     We have agreed to indemnify the underwriters against some liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make because of any of those
liabilities.

                                 LEGAL MATTERS

     The validity of the purchase contracts and the senior notes will be passed
upon for Chubb by Debevoise & Plimpton, New York, New York and for the
underwriters by Davis Polk & Wardwell, New York, New York. Debevoise & Plimpton
and Davis Polk & Wardwell will rely as to all matters of New Jersey law upon the
opinion of Drinker Biddle & Reath LLP, Florham Park, New Jersey, counsel to
Chubb.

                             THE CHUBB CORPORATION


     The Chubb Corporation is a holding company for a family of property and
casualty insurance companies known informally as the Chubb Group of Insurance
Companies ("Chubb Group"). Since 1882, the Chubb Group has provided property and
casualty insurance to businesses and individuals around the world. At December
31, 2002, we had total assets of $34.1 billion and shareholders' equity of $6.9
billion. According to A.M. Best, the Chubb Group is the 13th largest U.S.
property and casualty insurance group based on 2002 net written premiums. With
more than 13,000 employees, the Chubb Group serves commercial and personal
customers through 8,000 independent agents and brokers worldwide.


     Our property and casualty operations are divided into three strategic
business units. Chubb Commercial Insurance offers a full range of commercial
customer insurance products, including coverage for multiple peril, casualty,
workers' compensation and property and marine. Chubb Commercial Insurance is
known for writing niche business, where our expertise can add value for our
agents, brokers and policyholders. Chubb Specialty Insurance offers a wide
variety of specialized executive protection and professional liability products
for privately and publicly owned companies, financial institutions, professional
firms and healthcare organizations. Chubb Personal Insurance offers products for
individuals with fine homes and possessions who require more coverage choices
and higher limits than standard insurance policies.


     As a holding company, our ability to continue to pay dividends to
shareholders and to satisfy our obligations, including the payment of interest
and principal on debt obligations, relies on the availability of liquid assets
at the holding company, which is dependent in large part on the dividend paying
ability of our property and casualty insurance subsidiaries. Various state
insurance laws restrict our property and casualty insurance subsidiaries as to
the amount of dividends they may pay to us without the prior approval of
regulatory authorities. The restrictions are generally based on net income and
on certain levels of policyholders' surplus as determined in accordance with
statutory accounting practices. Dividends in excess of such thresholds are
considered "extraordinary" and require prior regulatory approval. The maximum
dividend distribution that may be made by our property and casualty subsidiaries
to us during 2003 without prior approval is approximately $445 million.



     Our principal executive offices are located at 15 Mountain View Road,
Warren, New Jersey 07061-1615, and our telephone number is (908) 903-2000.



                            THE CHUBB CAPITAL TRUSTS

     We created each trust as a Delaware statutory trust pursuant to a trust
agreement. We will enter into an amended and restated trust agreement for each
trust, which will state the terms and conditions for the trust to issue and sell
its preferred securities and common securities. We will amend and restate each
trust agreement in its entirety substantially in the form filed as an exhibit to
the registration statement which includes this prospectus. Each trust agreement
will be qualified as an indenture under the Trust Indenture Act of 1939, as
amended, which we refer to in this prospectus as the "Trust Indenture Act."

     Each trust exists for the exclusive purposes of:

     - issuing and selling to the public preferred securities, representing
       undivided beneficial interests in the assets of the trust;

     - issuing and selling to us common securities, representing undivided
       beneficial interests in the assets of the trust;

     - using the proceeds from the sale of the preferred securities and common
       securities to acquire a corresponding series of our junior subordinated
       deferrable interest debentures, which we refer to in this prospectus as
       the corresponding junior subordinated debentures;

     - distributing the cash payments it receives from the corresponding junior
       subordinated debentures it owns to you and the other holders of preferred
       securities and to us as the holder of common securities; and

     - engaging in other activities that are necessary, convenient, or
       incidental to these purposes.

     Accordingly, the corresponding junior subordinated debentures will be the
sole assets of each trust, and payments under the corresponding junior
subordinated debentures and a related expense agreement will be the sole revenue
of each trust.

     We will own all of the common securities of each trust. The common
securities of a trust will rank equally with and payments will be made pro rata
with the preferred securities of the trust, except that if an event of default
under a trust agreement then exists, our rights as holder of the common
securities to payment of distributions and payments upon liquidation or
redemption will be subordinated to your rights as a holder of the preferred
securities of the trust. See "Description of Preferred
Securities -- Subordination of Common Securities."

     Unless we state otherwise in a prospectus supplement, each trust has a term
of approximately 45 years. A trust may also terminate earlier. The trustees of
each trust will conduct its business and affairs. As holder of the common
securities we will appoint the trustees. Initially, the trustees will be:

     - Bank One Trust Company, N.A., which will act as property trustee; and

     - Bank One Delaware, Inc., which will act as Delaware trustee; and

     - Two of our employees or officers, who will act as administrative
       trustees.


     Bank One Trust Company, N.A., as property trustee, will act as sole
indenture trustee under each trust agreement for purposes of compliance with the
provisions of the Trust Indenture Act. Bank One Trust Company, N.A. will also
act as trustee under the guarantee and the junior subordinated indenture
pursuant to which we will issue the corresponding junior subordinated
debentures. See "Description of Junior Subordinated Debentures" and "Description
of Guarantee."


     The holder of the common securities of a trust, or the holders of a
majority in liquidation preference of the preferred securities, if an event of
default under the trust agreement has occurred and is continuing, will be
entitled to appoint, remove or replace the property trustee and/or the Delaware
trustee of the trust. You will not have the right to vote to appoint, remove or

                                        2


replace the administrative trustees. Only we, as the holder of the common
securities, will have those voting rights. The duties and obligations of the
trustees are governed by the applicable trust agreement. We will pay all fees
and expenses related to the trusts and any offering of the preferred securities
and will pay, directly or indirectly, all ongoing costs, expenses and
liabilities of the trusts, except for payments made on the preferred securities
or the common securities, subject to the guarantee.

     The principal executive office of each trust is c/o The Chubb Corporation,
15 Mountain View Road, Warren, New Jersey 07061-1615, Attention: Secretary, and
the telephone number of each trust is (908) 903-2000.

                                        3


                                USE OF PROCEEDS

     Unless we state otherwise in a prospectus supplement, we intend to use the
proceeds from the sale of the securities offered by this prospectus for general
corporate purposes. We will include a more detailed description of the use of
proceeds of any specific offering of securities in the prospectus supplement
relating to that offering.

                RATIO OF CONSOLIDATED EARNINGS TO FIXED CHARGES


     The following table sets forth our ratio of consolidated earnings to fixed
charges for each of the five years in the period ended December 31, 2002 and for
the quarter ended March 31, 2003:





                                                       FOR THE YEAR ENDED DECEMBER 31,
                            FOR THE THREE MONTHS   ---------------------------------------
                            ENDED MARCH 31, 2003   1998    1999    2000     2001     2002
                            --------------------   -----   -----   -----   ------   ------
                                                                  
Ratio of Earnings to Fixed
  Charges.................          7.92           16.03   10.40   11.48   0.49(1)  2.59(2)



---------------

(1) For the year ended December 31, 2001, consolidated earnings were not
    sufficient to cover fixed charges by $46.0 million. Consolidated earnings
    for the period, as defined, reflect a $635.0 million loss before income
    taxes from the September 11 attack in the United States and net surety bond
    losses before income taxes of $220.0 million arising from the bankruptcy of
    Enron Corp.

(2) Consolidated earnings, as defined, for the year ended December 31, 2002
    reflect net losses of $700.0 million before income taxes recognized in the
    third and fourth quarters related to asbestos and toxic waste claims and a
    reduction in net surety losses of $88.0 million before income taxes
    resulting from the settlement of litigation related to Enron.

     For the purpose of computing the above ratios of consolidated earnings to
fixed charges, consolidated earnings consist of income from continuing
operations before income taxes excluding income or loss from equity investees,
plus those fixed charges that were charged against income and distributions from
equity investees. Fixed charges consist of interest expense before reduction for
capitalized interest and the portion of rental expense (net of rental income
from subleased properties) which is considered to be representative of the
interest factors in the leases.

                         DESCRIPTION OF DEBT SECURITIES

     We may offer unsecured senior debt securities or subordinated debt
securities. We refer to the senior debt securities and the subordinated debt
securities together in this prospectus as the debt securities. We will issue the
senior debt securities in one or more series under an indenture, which we refer
to as the senior indenture, as supplemented from time to time between us and
Bank One Trust Company, N.A., as successor in interest to the First National
Bank of Chicago, as trustee. We will issue the subordinated debt securities in
one or more series under an indenture, which we refer to as the subordinated
indenture, as supplemented from time to time between us and Bank One Trust
Company, N.A., as successor in interest to the First National Bank of Chicago,
as trustee. We refer to the senior indenture and the subordinated indenture
together as the indentures.

     The following description of the terms and provisions of the debt
securities and the indentures is a summary. It summarizes only those terms of
the debt securities and portions of the indentures which we believe will be most
important to your decision to invest in our debt securities. You should keep in
mind, however, that it is the indentures, and not this summary, which define
your rights as a debtholder. There may be other provisions in the indentures
which are also important to you. You should read the indentures for a full
description of the terms of the debt. The senior indenture and the subordinated
indenture are incorporated by reference as exhibits to the registration
statement that includes this prospectus. See "Where You Can Find More
Information" for information on how to obtain copies of the senior indenture and
the subordinated indenture.


     For purposes of this section, "Chubb", "we", "us", and "our", refer solely
to The Chubb Corporation and not to any of its subsidiaries.


RANKING

     Our debt securities will be unsecured obligations. Our senior debt
securities will rank equally with all of our other unsecured and unsubordinated
obligations. Our subordinated debt securities will be subordinate and junior in
right of payment to all of our senior debt. See "-- Subordination Under the
Subordinated Indenture."

     Since we are a non-operating holding company, most of our operating assets
are owned by our subsidiaries. We rely primarily on dividends from these
subsidiaries to meet our obligations for payment of principal and interest on
our outstanding debt obligations and corporate expenses. Accordingly, the debt
securities will be effectively subordinated to all existing and future
liabilities of our subsidiaries, and you should rely only on our assets for
payments on the debt securities. The amount of dividend distributions to us from
our insurance subsidiaries may be restricted by state insurance laws and
regulations as administered by state insurance departments. See "The Chubb
Corporation."

     Unless we state otherwise in the applicable prospectus supplement, the
indentures do not limit us from incurring or issuing other secured or unsecured
debt under either of the indentures or any other indenture that we may have
entered into or enter into in the future. See "-- Subordination Under the
Subordinated Indenture" and the prospectus supplement relating to any offering
of subordinated debt securities.

TERMS OF THE DEBT SECURITIES

     We may issue debt securities in one or more series, through an indenture
that supplements the senior indenture or the subordinated indenture or through a
resolution of our board of directors or an authorized committee of our board of
directors.

all series of debt securities then outstanding), occurs and is continuing, with
respect to the debt securities of any series, then the trustee or the holders of
at least 25% in aggregate principal amount of the outstanding debt securities of
that series (each series acting as a separate class) may require us to repay
immediately the entire principal amount of the outstanding debt securities of
that series, or such lesser amount as may be provided in the terms of the
securities, together with all accrued and unpaid interest and premium, if any.
(Sections 5.1 and 5.10 of each indenture)



     If an Event of Default under an indenture specified in clause (4) occurs
and is continuing with respect to all series of debt securities then outstanding
under the relevant indenture or an Event of Default specified in clause (5)
occurs and is continuing, then the trustee or the holders of at least 25% in
aggregate principal amount of all of the debt securities then outstanding under
the relevant indenture (treated as one class) may require us to repay
immediately the entire principal amount of the outstanding debt securities, or
such lesser amount as may be provided in the terms of the securities, together
with all accrued and unpaid interest, if any. (Sections 5.1 and 5.10 of each
indenture)


     Any Event of Default with respect to a particular series of debt securities
under the relevant indenture may be waived by the holders of a majority of the
aggregate principal amount of the outstanding debt securities of such series, or
of all the outstanding debt securities under the relevant indenture, as the case
may be, except in each case a failure to pay principal of or premium, if any, or
interest on such debt security. (Sections 5.1 and 5.10 of each indenture)

                                        8


     The trustee will, within 90 days of the occurrence of an Event of Default
that has not been cured, provide notice to the holders of any series of debt
securities effected. The trustee may withhold notice to the holders of any
default, except in the payment of principal of or interest or premium on, or
sinking fund payment in respect of, the securities, if the trustee considers it
in the interest of the holders to do so. (Section 5.11 of each indenture)

     We are required to furnish to the trustee an annual statement as to
compliance with all conditions and covenants under the indenture. (Section 3.5
of each indenture)

MODIFICATION OF THE INDENTURES


     We may generally amend the indenture with the consent of the holders of a
majority in aggregate principal amount of the outstanding debt securities of
each series affected by the amendment. However, we may not amend the indentures
without the consent of each holder affected, in order to, among other things:


     - extend the final maturity of any debt security;

     - reduce the principal amount of any debt security;

     - reduce the rate or extend the time of payment of interest on any debt
       security;

     - reduce the amount payable on redemption of any debt security, or reduce
       the amount of principal of an original issue discount debt security that
       would be due and payable on an acceleration of the maturity of such debt
       security or the amount of such debt security provable in bankruptcy;

     - change the currency of payment of principal of or interest on any debt
       security;

     - extend the time or reduce the amount of any payment to any sinking fund
       or analogous obligation relating to any debt security;

     - impair or affect the right of any security holder to institute suit for
       payment on such security or any right of repayment at the option of the
       security holder;

     - reduce the percentage of debt securities of any series that must consent
       to an amendment to an indenture;

     - reduce the percentage of debt securities of any series necessary to
       consent to waive any past default under an indenture to less than a
       majority; or

     - modify any of the provisions of the sections of such indenture relating
       to supplemental indentures with the consent of the holders of debt
       securities, except to increase the percentage of holders or to provide
       that provisions of the indenture cannot be modified or waived without the
       consent of the holder of each affected debt security. (Section 8.2 of
       each indenture)

     A supplemental indenture which changes or eliminates any covenant or other
provision of an indenture which has expressly been included solely for the
benefit of one or more particular series of debt securities, or which modifies
the rights of the holders of debt securities of such series with respect to such
covenant or other provision, will not affect the rights under the indenture of
the holders of the debt securities of any other series. (Section 8.2 of each
indenture)

     We and the trustee may amend the indentures without the consent of any
holder of debt securities in order to:

     - secure any debt securities issued under such indenture;


     - evidence the succession of another corporation and assumption of our
       obligations in the case of a merger or consolidation;


     - add to the covenants of Chubb or add additional events of default;

     - cure ambiguities, defects or inconsistencies, provided that such action
       does not adversely affect any holders of securities issued under such
       indenture;

                                        9


     - establish the form and terms of debt securities of any series;

     - provide for a successor trustee with respect to one or more series of
       securities issued under such indenture or to provide for or facilitate
       the administration of the trusts under the indenture by more than one
       trustee;

     - permit or facilitate the issuance of securities in bearer form or provide
       for uncertificated securities to be issued under such indenture; or

     - change or eliminate any provision of such indenture, provided that any
       such change or elimination will become effective only when there is no
       security outstanding of any series created prior to the execution of such
       supplemental indenture which is entitled to the benefit of such
       provision. (Section 8.1 of each indenture)

SATISFACTION AND DISCHARGE


     Each indenture provides that when, among other things, all debt securities
of any outstanding series not previously delivered to the trustee for
cancellation:


     - have become due and payable; or

     - will become due and payable at their stated maturity within one year; or


     - are to be called for redemption within one year under arrangements
       satisfactory to the Trustee for the giving of notice of redemption by the
       Trustee,



and we deposit or cause to be deposited with the trustee, in trust, an amount in
cash or United States government obligations sufficient to pay and discharge the
entire indebtedness on the debt securities of that series not previously
delivered to the trustee for cancellation, for the principal, premium, if any,
and interest to the date of the deposit or to the stated maturity, as the case
may be, then the indenture will cease to be of further effect with respect to
all debt securities of that series, other than as to certain transfers and
exchanges and other rights identified in the indenture, and we will be deemed to
have satisfied and discharged the indenture with respect to all debt securities
of that series. However, we will continue to be obligated to pay all other sums
due under the indenture and to provide the officers' certificates and opinions
of counsel described in the indenture. (Section 10.1 of each indenture)


DEFEASANCE


     Unless we state otherwise in the applicable prospectus supplement, the
senior indenture provides that we will be deemed to have paid and discharged the
entire indebtedness with respect to all outstanding debt securities of any
series, other than as to certain transfers and exchanges, if, among other
things:



     - we irrevocably deposit with the trustee money in an amount in the
       currency or currencies in which the debt securities of that series are
       payable or cash or United States government obligations, or a combination
       thereof, as trust funds in an amount certified to be sufficient to pay on
       each date that they become due and payable, the principal of and interest
       on, all outstanding debt securities of such series;


     - we deliver to the trustee an opinion of counsel to the effect that:


      - the holders of the senior debt securities of such series will not
        recognize income, gain or loss for United States federal income tax
        purposes as a result of the defeasance; and



      - the defeasance will not otherwise alter those holders' United States
        federal income tax treatment of principal and interest payments on the
        senior debt securities of such series; this opinion must be based on a
        ruling of the Internal Revenue Service or a change in United States
        federal income tax law occurring after the date of this prospectus,
        since that result would not occur under current tax law; and


                                        10



     - no event of default under the senior indenture with respect to the debt
       securities of such series has occurred and is continuing.



     (Section 10.1 of the senior indenture)


GLOBAL SECURITIES

     The debt securities of a series may be issued in whole or in part in the
form of one or more global certificates that will be deposited with a depositary
identified in a prospectus supplement. Unless it is exchanged for debt
securities in definitive form, a global certificate may generally be transferred
only as a whole unless it is being transferred to certain nominees of the
depositary. Unless otherwise stated in the prospectus supplement the Depository
Trust Company, New York, New York, or DTC, will act as depositary.

     We will describe the specific terms of the depositary arrangement in the
applicable prospectus supplement. We expect that the following provisions will
generally apply to these depositary arrangements.

     BENEFICIAL INTERESTS IN A GLOBAL SECURITY

     Ownership of beneficial interests in a registered global security will be
limited to persons, called participants, that have accounts with the depositary
or persons that may hold interests through participants. Upon the issuance of a
registered global security, the depositary will credit, on its book-entry
registration and transfer system, the participants' accounts with the respective
principal or face amounts of the securities beneficially owned by the
participants. Any dealers, underwriters or agents participating in the
distribution of the securities will designate the accounts to be credited.
Ownership of beneficial interests in a registered global security will be shown
on, and the transfer of ownership interests will be effected only through,
records maintained by the depositary, 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 some purchasers
of securities take physical delivery of these securities in definitive form.
These laws may impair your ability to own, transfer or pledge beneficial
interests in registered global securities.


     So long as the depositary, or its nominee, is the registered owner of a
global security, that depositary or its nominee, as the case may be, will be
considered the sole owner or holder of the securities represented by the
registered global security for all purposes under the applicable indenture.
Except as described below, you:


     - will not be entitled to have the securities represented by the registered
       global security registered in your names;

     - will not receive or be entitled to receive physical delivery of the
       securities in definitive form; and

     - will not be considered the owners or holders of the securities under the
       indenture.

     PAYMENTS OF PRINCIPAL, PREMIUM AND INTEREST

     We will make principal, premium, if any, and interest payments on a
registered global security to the depositary that is the registered holder of
the global security or its nominee. The depositary for the global security will
be solely responsible and liable for all payments made on account of your
beneficial ownership interests in the registered global security and for
maintaining, supervising and reviewing any records relating to your beneficial
ownership interests.


     We expect that the depositary or its nominee, upon receipt of principal,
premium, if any, or interest payment in respect of a global security,
immediately will credit participants' accounts with amounts in proportion to
their respective beneficial interests in the principal amount of the global
security as shown on the records of the depositary or its nominee. We also
expect that payments by participants to you, as an owner of a beneficial
interest in a registered global security held through those participants, will
be governed by standing instructions and customary practices, as is now the


                                        11


case with securities held for the accounts of customers in bearer form or
registered in "street name." These payments will be the responsibility of those
participants.


PAYMENT AND PAYING AGENTS


     Unless we state otherwise in an applicable prospectus supplement, we will
pay principal of, premium, if any, and interest on your debt securities at the
office of the trustee in the City of New York or at the office of any paying
agent that we may designate.

     Unless we state otherwise in the applicable prospectus supplement, we will
pay any interest on debt securities to the registered owner of the debt security
at the close of business on the regular record date for the interest, except in
the case of defaulted interest. (Section 2.7 of each indenture) We may at any
time designate additional paying agents or rescind the designation of any paying
agent. We must maintain a paying agent in each place of payment for the debt
securities. (Section 3.2 of each indenture)


     Any moneys or government obligations deposited with, or paid to, the
trustee or any paying agent, or then held by us in trust, for the payment of the
principal of, and interest on, any debt security that remain unclaimed for three
years after the principal or interest has become due and payable will, at our
request, be repaid to us. After repayment to us, you are entitled to seek
payment only from us as a general unsecured creditor. (Section 10.4 of each
indenture)


CONVERSION OR EXCHANGE


     The subordinated indenture permits us to issue debt securities that we may
convert or exchange into common stock or other securities of Chubb. We will
describe the specific terms on which the subordinated debt securities may be
converted or exchanged in the applicable prospectus supplement. The conversion
or exchange may be mandatory, at your option, or at our option, as specified in
the applicable prospectus supplement. The applicable prospectus supplement will
describe the manner in which the shares of common stock or other securities you
would receive would be converted or exchanged.


SUBORDINATION UNDER THE SUBORDINATED INDENTURE


     The debt securities we issue under the subordinated indenture will
constitute part of the subordinated debt of Chubb. These subordinated debt
securities will be subordinate and junior in right of payment, to the extent and
in the manner set forth in the subordinated indenture, to all "senior
indebtedness" of Chubb. The subordinated indenture defines "senior indebtedness"
as the principal of, premium, if any, and unpaid interest on the following,
whether outstanding at the date of the subordinated indenture or later incurred
or created:


     - indebtedness of Chubb for money borrowed, including purchase money
       obligations, evidenced by notes or other written obligations;

     - indebtedness of Chubb evidenced by notes, debentures, bonds or other
       securities issued under the provisions of an indenture or similar
       instrument;

     - obligations of Chubb as lessee under capitalized leases and leases of
       property made as part of any sale and leaseback transactions;

     - indebtedness of others of any of the kinds described in the preceding
       clauses assumed or guaranteed by Chubb; and


     - renewals, extensions and refundings of, and indebtedness and obligations
       of a successor corporation issued in exchange for, or in replacement of,
       indebtedness and obligations described in the preceding clauses unless
       such indebtedness, obligation, renewal, extension or refunding expressly
       provides that it is not superior in right of payment to the subordinated
       debt securities;



provided, that senior indebtedness does not include any indebtedness issued
under the subordinated indenture or any indebtedness or obligation if the terms
of such indebtedness or obligation


                                        12



expressly provide that such indebtedness or obligation is not senior in right of
payment to the debt securities issued under the subordinated indenture or
expressly provide that such indebtedness or obligation is pari passu with or
junior to the debt securities issued under the subordinated indenture.



     The subordinated indenture does not limit the amount of senior indebtedness
that we may incur. (Subordinated indenture section 14.1)


     No payment of the principal or interest on the indebtedness evidenced by
the subordinated debt securities may be made if, at the time of such payment or
immediately after giving effect thereto, there exists any default with respect
to any senior indebtedness and the default is the subject of judicial
proceedings or if Chubb receives notice of the default from any holder of senior
indebtedness or a trustee for such senior indebtedness.


     Upon any acceleration of the maturity of any series of subordinated debt
securities resulting from an event of default, Chubb must give notice of the
acceleration to holders of the senior indebtedness and may not pay holders of
such series of subordinated debt securities until 120 days after the
acceleration and then only if all principal of, premium, if any, and interest on
senior indebtedness due at that time (whether by acceleration or otherwise) is
first paid in full. In the event of any payment or distribution of assets or
securities upon any dissolution, winding up, total or partial liquidation or
reorganization or similar proceeding relating to Chubb, all principal of,
premium, if any, and interest due on all senior indebtedness must be paid in
full before holders of the subordinated debt securities are entitled to receive
or retain any payment. As a result of such subordination, in the event of
insolvency, creditors of Chubb who are holders of senior indebtedness and
general creditors of Chubb, may recover more, ratably, than holders of the
subordinated debt securities. (Subordinated indenture sections 14.1, 14.2, 14.3)



     If this prospectus is being delivered in connection with a series of
subordinated debt securities, the accompanying prospectus supplement or the
information incorporated in this prospectus by reference will set forth the
approximate amount of senior indebtedness outstanding as of the end of the most
recent fiscal quarter.



GOVERNING LAW


     The debt securities and each indenture will be governed by and construed in
accordance with the laws of the State of New York.

INFORMATION CONCERNING THE TRUSTEES

     The trustee under each indenture will have all the duties and
responsibilities of an indenture trustee specified in the Trust Indenture Act.
Neither trustee is required to expend or risk its own funds or otherwise incur
personal financial liability in performing its duties or exercising its rights
and powers if it reasonably believes that it is not reasonably assured of
repayment or adequate indemnity. (Section 6.1 of each indenture.)


     Bank One Trust Company, N.A. is the trustee under the senior indenture and
will be the trustee under the subordinated indenture. The trustee's current
address is 153 West 51st Street, New York, New York 10019. Bank One is acting as
the successor to the original trustee, The First National Bank of Chicago.


                                        13


                 DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES

     We will issue the junior subordinated deferrable interest debentures, which
we refer to as the junior subordinated debentures, in one or more series under
an indenture, which we refer to as the junior subordinated indenture, as
supplemented from time to time, between us and Bank One Trust Company, N.A., as
debenture trustee.

     The following description of the terms of the junior subordinated
debentures and the junior subordinated indenture is a summary. It summarizes
only those terms of the junior subordinated debentures and the junior
subordinated indenture which we believe will be most important to your decision
to invest in our junior subordinated debentures. You should keep in mind,
however, that it is the junior subordinated indenture, and not this summary,
which defines your rights as a holder of our junior subordinated debentures.
There may be other provisions in the junior subordinated indenture which are
also important to you. You should read the junior subordinated indenture for a
full description of the terms of the junior subordinated debentures. The junior
subordinated indenture is filed as an exhibit to the registration statement that
includes this prospectus. See "Where You Can Find More Information" for
information on how to obtain a copy of the junior subordinated indenture.


     For purposes of this section, "Chubb", "we", "us" and "our" refer solely to
The Chubb Corporation and not to any of its subsidiaries.


RANKING

     Our junior subordinated debentures will be unsecured obligations. Each
series of junior subordinated debentures will rank equally with all other series
of junior subordinated debentures. Our junior subordinated debentures will be
subordinate and junior in right of payment, as described in the junior
subordinated indenture, to all of our debt other than debt which ranks equally
with or junior to the junior subordinated debentures. See "-- Subordination
under the Junior Subordinated Indenture."

     Since we are a non-operating holding company, most of our operating assets
are owned by our subsidiaries. We rely primarily on dividends from these
subsidiaries to meet our obligations for payment of principal and interest on
our outstanding debt obligations and corporate expenses. Accordingly, the junior
subordinated debentures will be effectively subordinated to all existing and
future liabilities of our subsidiaries, and you should rely only on our assets
for payments on the junior subordinated debentures. The amount of dividend
distributions to us from our insurance subsidiaries may be restricted by state
insurance laws and regulations as administered by state insurance departments.
See "The Chubb Corporation."

     Unless we state otherwise in the applicable prospectus supplement, the
junior subordinated indenture does not limit us from incurring or issuing other
secured or unsecured debt under the junior subordinated indenture or any other
indenture that we may have entered into or enter into in the future. See
"-- Subordination under the Junior Subordinated Indenture" and the prospectus
supplement relating to any offering of junior subordinated debentures.

TERMS OF THE JUNIOR SUBORDINATED DEBENTURES

Warrants."

                                        15


SPECIAL PAYMENT TERMS OF THE JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURES

     We may issue one or more series of junior subordinated debentures at a
substantial discount below their stated principal amount. These may bear no
interest or interest at a rate which at the time of issuance is below market
rates. We will describe United States federal income tax consequences and
special considerations relating to any series in the applicable prospectus
supplement.

     The purchase price of any of the junior subordinated debentures may be
payable in one or more foreign currencies or currency units. The junior
subordinated debentures may be denominated in one or more foreign currencies or
currency units, or the principal of, premium, if any, or interest on any junior
subordinated debentures may be payable in one or more foreign currencies or
currency units. We will describe the restrictions, elections, United States
federal income tax considerations, specific terms and other information relating
to the junior subordinated debentures and any foreign currencies or foreign
currency units in the applicable prospectus supplement.

     If we use any index to determine the amount of payments of principal of,
premium, if any, or interest on any series of junior subordinated debentures, we
will also describe in the applicable prospectus supplement the special United
States federal income tax, accounting and other considerations applicable to the
junior subordinated debentures.

DENOMINATIONS, REGISTRATION AND TRANSFER

     Unless we state otherwise in the applicable prospectus supplement, we will
issue the junior subordinated debentures in fully registered form without
coupons in denominations of $25 and integral multiples of $25. (Section 302)


     Except as we may describe in the applicable prospectus supplement, junior
subordinated debentures of any series will be exchangeable for other junior
subordinated debentures of the same series, in any authorized denominations, of
a like aggregate principal amount, of the same original issue date and stated
maturity and having the same terms. You may present junior subordinated
debentures for exchange as described above, or for registration of transfer, at
the office of the securities registrar or at the office of any transfer agent we
designate for that purpose. You will not incur a service charge but you will be
required to pay any taxes and other governmental charges as described in the
junior subordinated indenture. We will appoint the debenture trustee as
securities registrar under the junior subordinated indenture. We will specify
the transfer agent in the applicable prospectus supplement. We may at any time
designate additional transfer agents. (Section 305)


     If we redeem any junior subordinated debentures, neither we nor the
debenture trustee will be required to:


     - issue, transfer or exchange junior subordinated debentures during a
       period beginning at the opening of business 15 days before the day of
       selection for redemption of the junior subordinated debentures and ending
       at the close of business on the day of mailing of the relevant notice of
       redemption; or



     - transfer or exchange any junior subordinated debentures selected for
       redemption in whole or in part, except for any portion not redeemed of
       any junior subordinated debenture that is being redeemed in part.
       (Section 305)


REDEMPTION


     Unless we state otherwise in the applicable prospectus supplement, junior
subordinated debentures will not be subject to any sinking fund. (Section 1201)


                                        16



     Unless we state otherwise in the applicable prospectus supplement, we may,
at our option and at any time, redeem any series of junior subordinated
debentures, in whole or in part, at a redemption price equal to 100% of the
principal amount plus accrued and unpaid interest to the redemption date. We may
redeem junior subordinated debentures in part only in the amount of $25 or
integral multiples of $25 (or such other authorized denomination thereof).
(Sections 1101 and 1107)


     NOTICE OF REDEMPTION


     We will mail notice of any redemption of your junior subordinated
debentures not less than 30, nor more than 60 days before the redemption date to
you at your registered address. Unless we default in payment of the redemption
price, on and after the redemption date interest will cease to accrue on the
junior subordinated debentures or the portions called for redemption. (Section
1104)


OPTION TO EXTEND INTEREST PAYMENT DATE

     If provided in the applicable prospectus supplement, we will have the right
during the term of any series of junior subordinated debentures to extend the
interest payment period for a specified number of interest payment periods,
subject to the terms, conditions and covenants specified in the applicable
prospectus supplement. However, we may not extend these interest payments beyond
the maturity of the junior subordinated debentures. We will describe the United
States federal income tax consequences and special considerations relating to
any junior subordinated debentures in the applicable prospectus supplement.

     If we exercise this right, during the extension period we and our
subsidiaries may not:

     - declare or pay any dividends or distributions on, or redeem, purchase,
       acquire or make a liquidation payment on, any of our capital stock; or

     - make any payment of principal of, premium, if any, or interest on, or
       repay, repurchase or redeem any debt securities that rank equally with or
       junior in interest to the junior subordinated debentures or make any
       related guarantee payments,

other than:

     - dividends or distributions in our common stock;

     - redemptions or purchases of any rights pursuant to our rights plan, or
       any successor to our rights plan, and the declaration of a dividend of
       these rights in the future; and


     - payments under any Chubb guarantee of distributions on preferred
       securities of a Chubb trust under the applicable guarantee agreement.


     (Section 311)

CONSOLIDATION, MERGER AND SALE OF ASSETS


     We may not consolidate with or merge into any other corporation or convey,
transfer or lease all or substantially all of our properties and assets to any
individual, corporation, partnership, joint venture, association, joint-stock
company, trust, unincorporated organization or government or any agency or
political subdivision thereof, nor permit any such entity to consolidate with or
merge into us or convey, transfer or lease all or substantially all of its
properties and assets to us unless:



     - we are the surviving corporation or the successor corporation is a
       corporation organized under the laws of any domestic jurisdiction and
       assumes our obligations on the junior subordinated debentures and under
       the junior subordinated indenture;


                                        17



     - after giving effect to such transaction no Event of Default, and no event
       which, after notice or lapse of time or both, would become an Event of
       Default will have occurred and be continuing;



     - in the case of corresponding junior subordinated debentures, the
       transaction is permitted under the related trust agreement and guarantee
       and does not give rise to any breach or violation of the related trust
       agreement or guarantee; and



     - other conditions described in the junior subordinated indenture are met.


     This covenant would not apply to the direct or indirect conveyance,
transfer or lease of all or any portion of the stock, assets or liabilities of
any of our wholly owned subsidiaries to us or to our other wholly owned
subsidiaries. This covenant also would not apply to any recapitalization
transaction, a change of control of Chubb or a highly leveraged transaction
unless such transaction or change of control were structured to include a merger
of consolidation by us or the conveyance, transfer or lease of our assets
substantially as an entirety. (Section 801)

DEBENTURE EVENTS OF DEFAULT


     These are "Events of Default" under the junior subordinated indenture with
respect to each series of junior subordinated debentures:


     (1) failure to pay principal, or premium, if any, when due;

     (2) failure to pay any interest when due, continued for 30 days;

     (3) default in the payment of any sinking fund installment when due and
         payable;


     (4) failure to perform, or breach, of specified covenants or warranties of
         Chubb contained in the indenture for 90 days, after written notice from
         the debenture trustee or the holders of at least 25% in principal
         amount of the relevant series of outstanding junior subordinated
         debentures;


     (5) certain events of bankruptcy, insolvency or reorganization of Chubb;
         and

     (6) any other event of default described in the applicable board resolution
         or supplemental indenture under which the series of junior subordinated
         debentures is issued.


     If an Event of Default occurs and is continuing, the trustee may, and at
the written request of holders of a majority in aggregate principal amount of
the securities of each series affected by the Event of Default and upon the
trustee's receipt of indemnification to its satisfaction will, proceed to
protect and enforce its rights and those of the holders of such junior
subordinated debentures.



     If an Event of Default, other than an Event of Default specified in clause
(5) (or an event of default specified in clause (4) with respect to less than
all series of junior subordinated debentures then outstanding), occurs and is
continuing, with respect to the junior subordinated debentures of any series,
then the trustee or the holders of at least 25% in aggregate principal amount of
the outstanding junior subordinated debentures of that series (each series
acting as a separate class) may require us to repay immediately the entire
principal amount of the outstanding junior subordinated debentures of that
series, or such lesser amount as may be provided in the terms of the junior
subordinated debentures, together with all accrued and unpaid interest and
premium, if any. In the case of corresponding junior subordinated debentures, if
the debenture trustee or the holders of the corresponding junior subordinated
debentures fail to make this declaration, the holders of at least 25% in
aggregate liquidation preference of the corresponding series of preferred
securities will have that right. (Section 502)



     If an Event of Default specified in clause (4) occurs and is continuing
with respect to all series of junior subordinated debentures then outstanding
under the junior subordinated indenture or an Event of Default specified in
clause (5) occurs and is continuing, then the trustee or the holders of at least
25% in aggregate principal amount of all of the junior subordinated debentures
then outstanding under the junior subordinated indenture (treated as one class)
may require us to repay


                                        18



immediately the entire principal amount of the outstanding junior subordinated
debentures, or such lesser amount as may be provided in the terms of the junior
subordinated debentures, together with all accrued and unpaid interest, if any.
In the case of corresponding junior subordinated debentures, if the debenture
trustee or the holders of the corresponding junior subordinated debentures fail
to make this declaration, the holders of at least 25% in aggregate liquidation
preference of the corresponding series of preferred securities will have that
right. (Section 502)


     Any Event of Default with respect to a particular series of junior
subordinated debentures under the junior subordinated indenture may be waived by
the holders of a majority of the aggregate principal amount of the outstanding
junior subordinated debentures of such series, or of all the outstanding junior
subordinated debentures under the junior subordinated indenture, as the case may
be, except in each case a failure to pay principal of or premium, if any, or
interest on such junior subordinated debenture. (Section 502)


     The debenture trustee will, within 90 days after actual knowledge of the
debenture trustee of the occurrence of an Event of Default that has not been
cured, provide notice to the holders of any series of junior subordinated
debentures effected. The debenture trustee may withhold notice to the holders of
any default, except in the payment of principal of or interest or premium on, or
sinking fund payment in respect of, the junior subordinated debentures, if the
debenture trustee considers it in the interest of the holders to do so. (Section
602)



     We are required to furnish to the debenture trustee an annual statement as
to compliance with all conditions and covenants under the junior subordinated
indenture. (Section 1004)


     DIRECT ACTIONS BY PREFERRED SECURITY HOLDERS


     If a debenture event of default is attributable to our failure to pay
interest or principal on the corresponding junior subordinated debentures on the
date the interest, premium, if any, or principal is payable, you, as a holder of
preferred securities, may institute a legal proceeding directly against us,
which we refer to in this prospectus as a "direct action," for enforcement of
payment to you of the principal, of, premium, if any, or interest on the
corresponding junior subordinated debentures having a principal amount equal to
the aggregate liquidation preference of your related preferred securities.
(Section 508)


     We may not amend the junior subordinated indenture to remove the right to
bring a direct action without the prior written consent of the holders of all of
the preferred securities. If the right to bring a direct action is removed, the
applicable issue may become subject to the reporting obligations under the
Securities Exchange Act of 1934. We have the right under the junior subordinated
indenture to set-off any payment made to you as a holder of preferred securities
by us in connection with a direct action. You will not be able to exercise
directly any other remedy available to holders of the corresponding junior
subordinated debentures.

     You will not be able to exercise directly any remedies other than those
described in the preceding paragraph available to holders of the junior
subordinated debentures unless there has been an event of default under the
trust agreement.

MODIFICATION OF THE JUNIOR SUBORDINATED INDENTURE


     We and the debenture trustee may, without the consent of the holders of
junior subordinated debentures, amend, waive or supplement the junior
subordinated indenture for specified purposes, including, among other things,
curing ambiguities, defects or inconsistencies. However, no action may
materially adversely affect the interests of holders of any series of junior
subordinated debentures or, in the case of corresponding junior subordinated
debentures, the holders of the related series of preferred securities so long as
they remain outstanding. We may also amend the junior subordinated indenture to
maintain the qualification of the junior subordinated indenture under the Trust
Indenture Act. (Section 901)


                                        19



     We and the debenture trustee may modify and amend the junior subordinated
indenture in a manner affecting the rights of the holders of junior subordinated
debentures with the consent of the holders of not less than a majority in
aggregate principal amount of the outstanding junior subordinated debentures of
each series affected. However, no modification or amendment may, without the
consent of the holder of each outstanding junior subordinated debenture
affected:


     - change the stated maturity of the junior subordinated debentures;

     - reduce the principal amount of the junior subordinated debentures;

     - reduce the rate or, except as permitted by the junior subordinated
       indenture and the terms of the series of junior subordinated debentures,
       extend the time of payment of interest on the junior subordinated
       debentures; or

     - reduce the percentage of the holders of outstanding junior subordinated
       debentures necessary to modify or amend the junior subordinated
       indenture.

     (Section 902)

     In the case of corresponding junior subordinated debentures, so long as any
of the related series of preferred securities remain outstanding:

     - no such modification may be made that adversely affects the holders of
       the related series of preferred securities;

     - no termination of the junior subordinated indenture may occur; and

     - no waiver of any debenture event of default or compliance with any
       covenant under the junior subordinated indenture may be effective,

without the prior consent of the holders of at least a majority of the aggregate
liquidation preference of the related series of preferred securities unless the
principal of, and premium, if any, on, the corresponding junior subordinated
debentures and all accrued and unpaid interest on the corresponding junior
subordinated debentures have been paid in full and other conditions are
satisfied.


     In addition, we and the debenture trustee may execute, without your
consent, any supplemental indenture for the purpose of creating any new series
of junior subordinated debentures. (Section 902)


SATISFACTION AND DISCHARGE

     The junior subordinated indenture provides that when, among other things,
all junior subordinated debentures not previously delivered to the debenture
trustee for cancellation:

     - have become due and payable; or


     - will become due and payable at their stated maturity within one year of
       the date of deposit; or



     - are to be called for redemption within one year under arrangements
       satisfactory to the debenture trustee for the giving of notice of
       redemption by the debenture trustee;



and we deposit or cause to be deposited with the debenture trustee, in trust, an
amount in cash or United States government obligations sufficient to pay and
discharge the entire indebtedness on the junior subordinated debentures not
previously delivered to the debenture trustee for cancellation, for the
principal, premium, if any, and interest to the date of the deposit or to the
stated maturity, as the case may be, then the junior subordinated indenture will
cease to be of further effect and we will be deemed to have satisfied and
discharged the junior subordinated indenture. However, we will continue to be
obligated to pay all other sums due under the junior subordinated indenture and
to provide the officers' certificates and opinions of counsel described in the
junior subordinated indenture. (Section 401)


                                        20


DEFEASANCE


     Unless we state otherwise in the applicable prospectus supplement, the
junior subordinated indenture provides that we will be deemed to have paid and
discharged the entire indebtedness, other than as to certain transfers and
exchanges, with respect to all outstanding junior subordinated debentures of any
series if, among other things:


     - we irrevocably deposit with the trustee cash or United States government
       obligations or a combination thereof, as trust funds in an amount
       certified to be sufficient to pay on each date that they become due and
       payable, the principal of and interest on, all outstanding junior
       subordinated debentures of such series;


     - we deliver to the trustee an officers' certificate and an opinion of
       counsel to the effect that all conditions precedent in the junior
       subordinated indenture relating to the satisfaction and discharge of the
       entire indebtedness on the outstanding securities of such series have
       been complied with. (Section 403)


GLOBAL JUNIOR SUBORDINATED DEBENTURES

     The junior subordinated debentures of a series may be issued in whole or in
part in the form of one or more global junior subordinated debentures that will
be deposited with a depositary identified in a prospectus supplement. Unless it
is exchanged for junior subordinated debentures in definitive form, a global
junior subordinated debenture may not be transferred unless it is being
transferred to certain nominees of the depositary. Unless otherwise stated in
the prospectus supplement, the Depositary Trust Company, New York, New York, or
DTC, will act as depositary. We will issue global junior subordinated debentures
only in registered form and in either temporary or permanent form.

     We will describe the specific terms of the depositary arrangement in the
applicable prospectus supplement. We expect that the following provisions will
generally apply to these depositary arrangements.

     BENEFICIAL INTERESTS IN A GLOBAL JUNIOR SUBORDINATED DEBENTURE


     Ownership of beneficial interests in a registered global junior
subordinated debenture will be limited to persons, called participants, that
have accounts with the depositary or persons that may hold interests through
participants. Upon the issuance of a registered global junior subordinated
debenture, the depositary will credit, on its book-entry registration and
transfer system, the participants' accounts with the respective principal or
face amounts of the debentures beneficially owned by the participants. Any
dealers, underwriters or agents participating in the distribution of the
debentures will designate the accounts to be credited, or we will designate such
accounts if the junior subordinated debentures are issued directly by us.
Ownership of beneficial interests in a registered global junior subordinated
debenture will be shown on, and the transfer of ownership interests will be
effected only through, records maintained by the depositary, 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 some purchasers of debentures take physical delivery of these
debentures in definitive form. These laws may impair your ability to own,
transfer or pledge beneficial interests in registered global junior subordinated
debenture.



     So long as the depositary or its nominee is the registered owner of a
global junior subordinated debenture, the depositary or nominee will be
considered the sole owner or holder of the junior subordinated debentures
represented by the global junior subordinated debenture for all purposes under
the junior subordinated indenture. Except as provided below, you


     - will not be entitled to have any of the individual junior subordinated
       debentures represented by the global junior subordinated debenture
       registered in your name;

                                        21


     - will not receive or be entitled to receive physical delivery of any
       junior subordinated debentures in definitive form; and

     - will not be considered the owner or holder of the junior subordinated
       debentures under the junior subordinated indenture.

     PAYMENTS OF PRINCIPAL, PREMIUM AND INTEREST

     We will make principal, premium, if any, and interest payments on a
registered global junior subordinated debenture to the depositary that is the
registered holder of the global junior subordinated debenture or its nominee.
The depositary for the global junior subordinated debentures will be solely
responsible and liable for all payments made on account of your beneficial
ownership interests in the registered global junior subordinated debenture and
for maintaining, supervising and reviewing any records relating to your
beneficial ownership interests.


     We expect that the depositary or its nominee, upon receipt of principal,
premium, if any, or interest payment in respect of a global junior subordinated
debenture, immediately will credit participants' accounts with amounts in
proportion to their respective beneficial interests in the principal amount of
the global junior subordinated debenture as shown on the records of the
depositary or its nominee. We also expect that payments by participants to you,
as an owner of a beneficial interest in a registered global junior subordinated
debenture held through those participants, will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name."
These payments will be the responsibility of those participants.



PAYMENT AND PAYING AGENTS


     Unless we state otherwise in the applicable prospectus supplement, we will
pay principal of, premium, if any, and interest on your junior subordinated
debentures at the office of the debenture trustee in the City of New York or at
the office of any paying agent that we may designate.

     Unless we state otherwise in the applicable prospectus supplement, we will
pay any interest on junior subordinated debentures to the registered owner of
the junior subordinated debenture at the close of business on the regular record
date for the interest, except in the case of defaulted interest. (Section 307)
We may at any time designate additional paying agents or rescind the designation
of any paying agent. We must maintain a paying agent in each place of payment
for the junior subordinated debentures. (Section 1002)


     Any moneys deposited with the debenture trustee or any paying agent, or
then held by us in trust, for the payment of the principal of, premium, if any,
and interest on any junior subordinated debenture that remain unclaimed for two
years after the principal, premium, if any, or interest has become due and
payable will, at our request, be repaid to us. After repayment to us, you are
entitled to seek payment only from us as a general unsecured creditor. (Section
1003)


CONVERSION OR EXCHANGE


     The junior subordinated indenture permits us to issue junior subordinated
debentures that we may convert or exchange into preferred securities or other
securities or property of Chubb. We will describe the specific terms on which
junior subordinated debentures may be converted or exchanged in the applicable
prospectus supplement. The conversion or exchange may be mandatory, at your
option or at our option. The applicable prospectus supplement will state the
manner in which the preferred securities or other securities you would receive
would be converted or exchanged.


                                        22


SUBORDINATION UNDER THE JUNIOR SUBORDINATED INDENTURE

     The junior subordinated debentures we issue under the junior subordinated
indenture will constitute part of the subordinated debt of Chubb. These junior
subordinated debentures will be subordinate and junior in right of payment, to
the extent and in the manner set forth in the junior subordinated indenture, to
all "senior indebtedness" of Chubb. The junior subordinated indenture defines
"senior indebtedness" as the principal of, premium, if any, and unpaid interest
on the following, whether outstanding at the date of the junior subordinated
indenture or later incurred or created:

     - indebtedness of Chubb for money borrowed, including purchase money
       obligations, evidenced by notes or other written obligations;

     - indebtedness of Chubb evidenced by notes, debentures, bonds or other
       securities issued under the provisions of an indenture or similar
       instrument;

     - obligations of Chubb as lessee under capitalized leases and leases of
       property made as part of any sale and leaseback transactions;

     - indebtedness of others of any of the kinds described in the preceding
       clauses assumed or guaranteed by Chubb; and


     - renewals, extensions and refundings of, and indebtedness and obligations
       of a successor corporation issued in exchange for, or in replacement of,
       indebtedness and obligations described in the preceding clauses unless
       such indebtedness, obligation, renewal, extension or refunding expressly
       provides that it is not superior in right of payment to the subordinated
       debt securities;



provided, that senior indebtedness does not include any indebtedness issued
under the junior subordinated indenture or any indebtedness or obligation if the
terms of such indebtedness or obligation expressly provide that such
indebtedness or obligation is not senior in right of payment to junior
subordinated debentures issued under the junior subordinated indenture or
expressly provide that such indebtedness or obligation is pari passu with or
junior to junior subordinated debentures issued under the junior subordinated
indenture.


     The junior subordinated indenture does not limit the amount of senior
indebtedness that we may incur.


     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to us, the holders of senior debt will first be
entitled to receive payment in full of principal of, premium, if any, and
interest on the senior debt before the holders of junior subordinated debentures
or, in the case of corresponding junior subordinated debentures, the property
trustee on behalf of the holders, will be entitled to receive or retain any
payment of the principal, premium, if any, or interest on the junior
subordinated debentures.



     If the maturity of any junior subordinated debentures is accelerated, the
holders of all senior debt outstanding at the time of the acceleration will
first be entitled to receive payment in full of all amounts due, including any
amounts due upon acceleration, before you will be entitled to receive any
payment of the principal of, premium, if any, or interest on the junior
subordinated debentures.


     No payment of the principal or interest on the indebtedness evidenced by
the junior subordinated debentures may be made if, at the time of such payment
or immediately after giving effect thereto, there exists any default with
respect to any senior indebtedness and the default is the subject of judicial
proceedings or if Chubb receives notice of the default from any holder of senior
indebtedness or a trustee for such senior indebtedness. (Section 1304)

                                        23



     If this prospectus is being delivered in connection with a series of junior
subordinated debentures, the accompanying prospectus supplement or the
information incorporated in this prospectus by reference will set forth the
approximate amount of senior indebtedness outstanding as of the end of the most
recent fiscal quarter.


GOVERNING LAW

     The junior subordinated indenture and the junior subordinated debentures
will be governed by and construed in accordance with the laws of the State of
New York.

INFORMATION CONCERNING THE DEBENTURE TRUSTEE

     The trustee under the junior subordinated indenture will have all the
duties and responsibilities of an indenture trustee specified in the Trust
Indenture Act. The debenture trustee is not required to expend or risk its own
funds or otherwise incur personal financial liability in performing its duties
or exercising its rights and powers if it reasonably believes that it is not
reasonably assured of repayment or adequate indemnity.

     Bank One Trust Company, N.A. is the debenture trustee under the junior
subordinated indenture. The trustee's current address is 153 West 51st Street,
New York, New York 10019.

                          DESCRIPTION OF CAPITAL STOCK


GENERAL

     Our restated certificate of incorporation, as amended, authorizes us to
issue 600,000,000 shares of common stock, par value $1.00 per share, and
4,000,000 shares of preferred stock, par value $1.00 per share. As of December
31, 2002 there were issued 180,296,834 shares of common stock, of which
9,095,162 were treasury shares and 171,201,672 were outstanding, and we had no
preferred stock issued or outstanding. Holders of common stock have received a
right entitling them, when the right becomes exercisable to purchase shares of
Series B Participating Cumulative Preferred Stock. See "-- Shareholders Rights
Plan."


     In November 2002, we issued 24 million mandatorily exercisable warrants to
purchase shares of our common stock. The warrants were issued as part of our 7%
equity units and must be exercised on or prior to November 16, 2005. For further
discussion of the warrants and equity units, including the number of common
shares issuable thereunder, see our Annual Report on Form 10-K for the year
ended December 31, 2002, incorporated herein by reference.



     The following description of our capital stock is a summary. It summarizes
only those aspects of our capital stock which we believe will be most important
for your decision to invest in our capital stock. You should keep in mind,
however, that it is our restated certificate of incorporation, as amended, our
bylaws, as amended, and the New Jersey Business Corporation Act, and not this
summary, which define your rights as a holder of our capital stock. There may be
other provisions in these documents which are also important to you. You should
read these documents for a full description of the terms of our capital stock.
Our restated certificate of incorporation, as amended, and our bylaws, as
amended, are incorporated by reference as exhibits to the registration statement
that includes this prospectus. See "Where You Can Find More Information" for
information on how to obtain copies of these documents.

holders of common stock have one vote per share on all matters submitted to a
vote of the shareholders, and the right to the net assets of Chubb in

course of its business, and for any liquidation, dissolution or amendment of the
certificate of incorporation. All other shareholder action is decided by a
majority of the votes cast at a meeting of shareholders.

     Our bylaws, as amended, provide that the annual meeting of shareholders
will be held on such date and at such time as shall be designated by the board
of directors and as stated in a written notice which is mailed or delivered to

meeting.

                                        25



     Our restated certificate of incorporation, as amended, further provides

except that with respect to each series the board of directors may fix, among
other things:

     - the rate of dividends payable on the preferred stock;

     - the time and prices of redemption;

     - the amount payable upon voluntary redemption;

     - the retirement or sinking fund, if any;

     - the conversion rights, if any;

      - the creation of indebtedness of Chubb or any subsidiary of Chubb; or

      - the issuance of stock ranking on a parity with or senior to the shares
        of preferred stock either as to dividends or on liquidation;

     - the restrictions, if any, on:

      - the payment of dividends on common stock;

      - the acquisition of common stock; or

      - any other class or classes of stock of Chubb, other than preferred
        stock, ranking on a parity with or junior to the shares of preferred
        stock either as to dividends or on liquidation; and

     - the number of shares to comprise such series.

     Each series of preferred stock will be entitled to receive an amount
payable on liquidation, dissolution or winding up, fixed for each series, plus
all dividends accumulated to the date of final distribution, before any payment
or distribution of assets of Chubb is made on common stock. Shares of preferred
stock that have been issued and reacquired in any manner by Chubb, including
shares redeemed, shares purchased and retired and shares that have been
converted into shares of another series or class, may be reissued as part of the
same or another series of preferred stock. In accordance with our restated
certificate of incorporation, as amended, the 4,000,000 authorized but

                                        26


unissued shares of preferred stock may be issued pursuant to resolution of the
board of directors without the vote of the holders of any capital stock of
Chubb.

SHAREHOLDERS RIGHTS PLAN

     We have a shareholder rights agreement under which each shareholder has a
right for each share of common stock held. Each right entitles the registered
holder to purchase from Chubb a unit consisting of one one-thousandth of a share
of Series B Participating Cumulative Preferred Stock, par value $1.00 per share,
at a purchase price of $240 per unit. The rights are subject to adjustment to
prevent dilution of the interests represented by each right. The description and
terms of the rights are set forth in a rights agreement between Chubb and
EquiServe Trust Company, N.A., as rights agent. We have summarized portions of
the rights agreement. The summary is not complete. The rights agreement has been
filed as an exhibit to the registration statement that we have filed with the
SEC and that includes this prospectus. You should read the rights agreement for
the provisions that may be important to you.

     The shareholder rights plan is reviewed and evaluated at least once each
year by a committee of independent directors to determine if the maintenance of
the shareholder rights plan continues to be in the best interest of Chubb, its
shareholders and any other relevant constituencies of Chubb. Following a review,
the committee of independent directors will communicate its conclusions to the
full board of directors, including any recommendation as to whether the
shareholder rights plan should be modified or the rights should be redeemed.

     DISTRIBUTION DATE

     The rights are attached to all outstanding shares of common stock and trade
with the common stock until the rights become exercisable, and no separate
rights certificates will be distributed. The rights will separate from the
common stock and a distribution date will occur upon the earlier of either of
the following:

     - 10 days following the date of any public announcement that a person or
       group of affiliated or associated persons, referred to in this prospectus
       as an acquiring person, has acquired beneficial ownership of 20% or more
       of the outstanding shares of common stock; or

     - 10 business days following the commencement of a tender offer or exchange
       offer that would result in a person or group becoming an acquiring
       person.

     The rights are not exercisable until the distribution date and will expire
at the close of business on March 12, 2009 unless previously redeemed by Chubb
as described below.

     EVIDENCE OF RIGHTS

     Until the distribution date, or earlier redemption or expiration of the
rights:

     - the rights will be evidenced by the common stock certificates and will be
       transferred with and only with such common stock certificates;

     - new common stock certificates issued after March 31, 1999 will contain a
       notation incorporating the rights agreement by reference; and

     - the surrender for transfer of any certificates for common stock will also
       constitute the transfer of the rights associated with the common stock
       represented by such certificates.

     As soon as practicable after the distribution date, rights certificates
will be mailed to holders of record of common stock as of the close of business
on the distribution date and, thereafter the separate rights certificates alone
will represent the rights. Except as otherwise determined by the board of
directors, only shares of common stock issued prior to the distribution date
will be issued with rights.

                                        27


     TRIGGERING EVENT AND EFFECT OF TRIGGERING EVENT

     If any person becomes an acquiring person:

     - proper provision will be made so that each holder of a right, other than
       rights that are, or (under the circumstances specified in the rights
       agreement) were, beneficially owned by an acquiring person (which will
       thereafter be void), will have the right to receive upon exercise the
       number of shares of common stock having a market value of two times the
       exercise price of the right; or

     - at the option of our board of directors, at any time until such acquiring
       person becomes the beneficial owner of 50% or more of the shares of
       common stock, Chubb may exchange the rights, other than rights that are,
       or (under the circumstances specified in the rights agreement) were,
       beneficially owned by an acquiring person (which will thereafter be
       void), for shares of common stock at an exchange ratio of one share of
       common stock per right, appropriately adjusted to reflect any stock
       split, stock dividend or similar transaction. If, at any time following
       the date of any public announcement that an acquiring person has acquired
       beneficial ownership of 20% or more of the outstanding shares of common
       stock, Chubb is acquired in a merger or other business combination
       transaction, or 50% or more of Chubb's assets or earning power is sold,
       each holder of a right shall thereafter have the right to receive, upon
       exercise, common stock of the acquiring company having a value equal to
       two times the exercise price of the right. The events described in this
       paragraph are referred to as triggering events.

     ADJUSTMENTS

     The purchase price payable, and the number of units of preferred stock or
other securities or property issuable, upon exercise of the rights are subject
to adjustment from time to time to prevent dilution upon the occurrence of one
of the following:

     - in the event of a stock dividend on, or a subdivision, combination or
       reclassification of, the preferred stock;

     - if holders of the preferred stock are granted rights or warrants to
       subscribe for preferred stock, or convertible securities at less than the
       current market price of the preferred stock; or

     - upon the distribution to holders of the preferred stock of evidences of
       indebtedness or assets (excluding regular quarterly cash dividends) or of
       subscription rights or warrants (other than those referred to above).

     No adjustment in the purchase price will be required until cumulative
adjustments amount to at least 1% of the purchase price. No fractional units
will be issued and, in lieu of fractional units, an adjustment in cash will be
made based on the market price of the preferred stock on the last trading date
prior to the date of exercise.

     REDEMPTION

     The rights may be redeemed in whole, but not in part, at a price of $.01
per right by the board of directors at any time prior to the earlier of:

     - a person or group of persons becoming an acquiring person; and

     - March 12, 2009.

     Immediately upon the action of the board of directors ordering redemption
of the rights, the rights will terminate and thereafter the only right of the
holders of rights will be to receive the redemption price.

     Until a right is exercised, the holder will have no rights as a shareholder
of Chubb (beyond those as an existing shareholder), including the right to vote
or to receive dividends. As long as the rights are attached to the common stock,
Chubb will issue one right with each new share of common stock issued.

                                        28


                        DESCRIPTION OF DEPOSITARY SHARES

     We may elect to offer depositary shares representing receipts for
fractional interests in debt securities, junior subordinated debentures or
preferred stock. In this case, we will issue receipts for depositary shares,
each of which will represent a fraction of a debt security, junior subordinated
debenture or share of a particular series of preferred stock, as the case may
be.

     We will deposit the debt securities, junior subordinated debentures or
shares of any series of preferred stock represented by depositary shares under a
deposit agreement between us and a depositary which we will name in the
applicable prospectus supplement. Subject to the terms of the deposit agreement,
as an owner of a depositary share you will be entitled, in proportion to the
applicable fraction of a debt security, junior subordinated debenture or share
of preferred stock represented by the depositary share, to all the rights and
preferences of the debt security, junior subordinated debenture or preferred
stock, as the case may be, represented by the depositary share, including, as
the case may be, interest, dividend, voting, redemption, sinking fund, repayment
at maturity, subscription and liquidation rights.

     The following description of the terms of the deposit agreement is a
summary. It summarizes only those terms of the deposit agreement which we
believe will be most important to your decision to invest in our depositary
shares. You should keep in mind, however, that it is the deposit agreement, and
not this summary, which defines your rights as a holder of depositary shares.
There may be other provisions in the deposit agreement which are also important
to you. You should read the deposit agreement for a full description of the
terms of the depositary shares. The form of the deposit agreement is filed as an
exhibit to the registration statement that includes this prospectus. See "Where
You Can Find More Information" for information on how to obtain a copy of the
deposit agreement.

INTEREST, DIVIDENDS AND OTHER DISTRIBUTIONS

     The depositary will distribute all payments of interest, cash dividends or
other cash distributions received on the debt securities, junior subordinated
debentures or preferred stock, as the case may be, to you in proportion to the
number of depositary shares that you own.

     In the event of a payment of interest or distribution other than in cash,
the depositary will distribute property received by it to you in an equitable
manner, unless the depositary determines that it is not feasible to make a
distribution. In that case the depositary may sell the property and distribute
the net proceeds from the sale to you.

REDEMPTION OF DEPOSITARY SHARES

     If we redeem a series of debt securities, junior subordinated debentures or
preferred stock represented by depositary shares, the depositary will redeem
your depositary shares from the proceeds received by the depositary resulting
from the redemption. The redemption price per depositary share will be equal to
the applicable fraction of the redemption price per debt security, junior
subordinated debenture or share of preferred stock, as the case may be, payable
in relation to the redeemed series of debt securities, junior subordinated
debentures or preferred stock. Whenever we redeem debt securities, junior
subordinated debentures or shares of preferred stock held by the depositary, the
depositary will redeem as of the same redemption date the number of depositary
shares representing, as the case may be, the debt securities, junior
subordinated debentures or shares of preferred stock redeemed. If fewer than all
the depositary shares are to be redeemed, the depositary shares to be redeemed
will be selected by lot, proportionately or by any other equitable method as the
depositary may determine.

                                        29


VOTING THE PREFERRED STOCK OR EXERCISE OF RIGHTS UNDER THE INDENTURES OR THE
JUNIOR SUBORDINATED INDENTURE


     Upon receipt of notice of any meeting at which you are entitled to vote, or
of any request for instructions or directions from you as holder of debt
securities, junior subordinated debentures or preferred stock, the depositary
will mail to you the information contained in that notice. Each record holder of
the depositary shares on the record date will be entitled to instruct the
depositary how to vote the amount of the preferred stock represented by that
holder's depositary shares or how to give instructions or directions with
respect to the debt securities, junior subordinated debentures or preferred
stock, as the case may be, represented by that holder's depository shares. The
record date for the depositary shares will be the same date as the record date
for the debt securities, junior subordinated debentures or preferred stock, as
the case may be. The depositary will endeavor, to the extent practicable, to
vote the amount of the preferred stock, or to give instructions or directions
with respect to the debt securities or junior subordinated debentures, as the
case may be, represented by the depositary shares in accordance with those
instructions. We will agree to take all reasonable action which the depositary
may deem necessary to enable the depositary to do so. The depositary will
abstain from voting shares of the preferred stock or giving instructions or
directions with respect to the debt securities or junior subordinated
debentures, as the case may be, if it does not receive specific instructions
from you.


AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

     We and the depositary may amend the form of depositary receipt evidencing
the depositary shares and any provision of the deposit agreement at any time.
However, any amendment which materially and adversely alters the rights of the
holders of the depositary shares will not be effective unless the amendment has
been approved by the holders of at least a majority of the depositary shares
then outstanding.

     The deposit agreement will terminate if:

     - all outstanding depositary shares have been redeemed; or

     - there has been a final distribution in respect of the preferred stock,
       including in connection with our liquidation, dissolution or winding up,
       or a complete repayment or redemption of the debentures or junior
       subordinated debentures and the distribution, repayment or redemption
       proceeds, as the case may be, have been distributed to you.

RESIGNATION AND REMOVAL OF DEPOSITARY

     The depositary may resign at any time by delivering to us notice of its
election to do so. We also may, at any time, remove the depositary. Any
resignation or removal will take effect upon the appointment of a successor
depositary and its acceptance of such appointment. We must appoint the successor
depositary within 60 days after delivery of the notice of resignation or
removal. The successor depositary must be a bank or trust company having its
principal office in the United States and having a combined capital and surplus
of at least $50,000,000.

CHARGES OF DEPOSITARY


     We will pay all transfer and other taxes and governmental charges arising
solely from the existence of the depositary arrangements. We will pay charges of
the depositary in connection with the initial deposit of the debt securities,
junior subordinated debentures or preferred stock, as the case may be, and
issuance of depositary receipts, all withdrawals of shares of debt securities,
junior subordinated debentures or preferred stock, as the case may be, by you
and any repayment or redemption of the debt securities, junior subordinated
debentures or preferred stock, as the case may be. You will pay other transfer
and other taxes and governmental charges, as well as the other charges that are
expressly provided in the deposit agreement to be for your account.


                                        30


MISCELLANEOUS


     The depositary will forward all reports and communications from us which
are delivered to the depositary and which we are required or otherwise determine
to furnish to holders of debt securities, junior subordinated debentures or
preferred stock, as the case may be.



     Neither we nor the depositary will be liable under the deposit agreement to
you other than for the depositary's gross negligence, willful misconduct or bad
faith. Neither we nor the depositary will be obligated to prosecute or defend
any legal proceedings relating to any depositary shares, debt securities, junior
subordinated debentures or preferred stock unless satisfactory indemnity is
furnished. We and the depositary may rely upon written advice of counsel or
accountants, or upon information provided by persons presenting debt securities,
junior subordinated debentures or preferred stock for deposit, you or other
persons believed to be competent and on documents which we and the depositary
believe to be genuine.


                                        31


                            DESCRIPTION OF WARRANTS

     We may issue warrants, including warrants to purchase debt securities,
preferred stock or common stock. We may issue warrants independently or together

bank or trust company, as warrant agent, that we will describe in the prospectus
supplement relating to the warrants that we offer.

     The following description of the terms of the warrants is a summary. It
summarizes only those terms of the warrants and the warrant agreement which we
believe will be most important to your decision to invest in our warrants. You
should keep in mind, however, that it is the warrant agreement and the warrant
certificate relating to the warrants, and not this summary, which defines your
rights as a warrantholder. There may be other provisions in the warrant
agreement and the warrant certificate relating to the warrants which are also
important to you. You should read these documents for a full description of the

     We may issue stock purchase contracts, including contracts obligating you
to purchase from us, and us to sell to you, a specific number of shares of

of preferred stock or common stock may be fixed at the time the stock purchase
contracts are issued or may be determined by reference to a specific formula
described in the stock purchase contracts. We may issue stock purchase contracts
separately or as a part of units each consisting of a stock purchase contract
and debt securities, preferred securities or debt obligations of third parties,
including United States Treasury securities, securing your obligations to
purchase the preferred stock or the common stock under the stock purchase
contract. The stock purchase contracts may require us to make periodic payments
to you or vice versa and the payments may be unsecured or prefunded on some

                                        34


                      DESCRIPTION OF PREFERRED SECURITIES

     The trustees of each trust will issue on behalf of the trust preferred
securities and common securities of the trust. The preferred securities will
represent preferred undivided beneficial interests in the assets of the related
trust. As a holder of preferred securities of the trust, you will generally be
entitled to a preference with respect to distributions and amounts payable on
redemption or liquidation over the common securities of the trust, as well as
other benefits as described in the corresponding trust agreement. Each of the
trusts is a legally separate entity and the assets of one are not available to
satisfy the obligations of any of the others.

     The following description of the terms of the preferred securities and form
of trust agreement is a summary. It summarizes only those features of the
preferred securities and terms of the form of trust agreement which we believe
will be most important to your decision to invest in the preferred securities.
You should keep in mind, however, that it is the applicable trust agreement and
form of amended and restated trust agreement and not this summary, which define
your rights as a holder. There may be other provisions in the trust agreement
and form of amended and restated trust agreement which are also important to
you. You should read these documents for a full description of the terms of the
preferred securities. They are filed as exhibits to the registration statement
that includes this prospectus. See "Where You Can Find More Information" for
information on how to obtain copies of these documents.

     Each trust agreement will be qualified under the Trust Indenture Act. The
terms of the preferred securities of each trust will include those stated in the
applicable trust agreement and those made part of the trust agreement by
reference to the Trust Indenture Act. The amended and restated trust agreement
for each trust will be executed at the time the trust issues any preferred
securities and will be filed with the Securities and Exchange Commission on Form
8-K or by a post-effective amendment to the registration statement that includes
this prospectus. You should also read the applicable prospectus supplement,
which will contain additional information and may update or change some of the
information below.

GENERAL

     The trust agreement for each trust authorizes the administrative trustees
to issue on behalf of the trust preferred securities that have the terms
described in this prospectus and in the applicable prospectus supplement. The
preferred securities will represent undivided beneficial interests in the assets
of the applicable trust. The proceeds from the sale of each trust's preferred
and common securities will be used by the trust to purchase a series of
corresponding junior subordinated debentures that we issue. The corresponding
junior subordinated debentures will be held in trust by the property trustee for
the benefit of the holders of the preferred and common securities of the
applicable trust.

     The terms of the preferred securities of each trust will mirror the terms
of the corresponding junior subordinated debentures held by the applicable
trust. If interest payments on the corresponding junior subordinated debentures
held by the applicable trust are deferred as described below, distributions on
the preferred securities will also be deferred. The assets of the trust
available for distribution to the holders of its preferred securities generally
will be limited to payments under the series of corresponding junior
subordinated debentures held by the trust.

     Under the guarantee agreement related to each trust, we will agree to make
payments of distributions and payments on redemption or liquidation with respect
to the trust's preferred securities, but only to the extent the trust has funds
available to make those payments and has not made the payments. Our obligations
under the applicable guarantee, expense agreement, trust agreement, junior
subordinated indenture and corresponding junior subordinated debentures will
provide a full, irrevocable and unconditional commitment by us regarding amounts
due on the preferred securities issued by each trust. See "Relationship Among
the Preferred Securities, the Corresponding Junior Subordinated Debentures and
the Guarantees."
                                        35


RANKING OF PREFERRED SECURITIES

     The preferred securities of a trust will rank equally, and we will make
payments proportionately with the common securities of the trust except as
described under "-- Subordination of Common Securities." The preferred
securities of each trust represent preferred undivided beneficial interests in
the assets of the trust. The property trustee will hold legal title to the
corresponding junior subordinated debentures in trust for the benefit of the
holders of the related preferred securities and common securities.

     Each guarantee agreement that we execute for your benefit, as a holder of
preferred securities of a trust, will be a guarantee on a subordinated basis
with respect to the related preferred securities. However, our guarantee will
not guarantee payment of distributions or amounts payable on redemption or
liquidation of the preferred securities when the related trust does not have
funds on hand available to make such payments. See "Description of Guarantee."

DISTRIBUTIONS ON THE PREFERRED SECURITIES

     Each trust will pay the distributions on the preferred securities and
common securities at a rate specified in the applicable prospectus supplement.

     The amount of distributions the trust must pay for any period will be
computed on the basis of a 360-day year of twelve 30-day months unless we
otherwise specify in the applicable prospectus supplement. Distributions that
are in arrears may bear interest at the rate per annum specified in the
applicable prospectus supplement. The term "distributions" as we use it in this
prospectus includes any additional amounts provided in the trust agreement.

     Distributions on the preferred securities will be cumulative, will accrue
from the date of original issuance and will be payable on the dates specified in
the applicable prospectus supplement. If any date on which distributions are
payable on the preferred securities is not a business day, the trust will
instead make the payment on the next succeeding day that is a business day, and
without any interest or other payment on account of the delay. However, if that
business day is in the next succeeding calendar year, the trust will make the
payment on the immediately preceding business day. In each case payment will be
made with the same force and effect as if made on the date the payment was
originally due. When we use the term "business day" in this prospectus, we mean
any day other than a Saturday or a Sunday, or a day on which banking
institutions in the City of New York are authorized or required by law or
executive order to remain closed or a day on which the corporate trust office of
the property trustee or the debenture trustee is closed for business.

     If provided in the applicable prospectus supplement, we have the right
under the junior subordinated indenture, which is the contract that provides the
terms for the corresponding junior subordinated debentures, to extend the
interest payment period for a specified number of periods. However, we may not
extend these interest payments beyond the maturity of the corresponding junior
subordinated debentures. As a consequence of any extension, distributions on the
related preferred securities would be deferred by the trust during the extension
period. These distributions would continue to accumulate additional
distributions at the rate per annum set forth in the prospectus supplement.

     If we exercise this right, during the extension period we and our
subsidiaries may not:

     - declare or pay any dividends or distributions on, or redeem, purchase,
       acquire or make a liquidation payment on, any of our capital stock; or

     - make any payment of principal, premium, if any, or interest on or repay,
       repurchase or redeem any debt securities that rank equally with or junior
       in interest to the corresponding junior subordinated debentures or make
       any related guarantee payments,

                                        36


other than:

     - dividends or distributions in our common stock;

     - redemptions or purchases of any rights pursuant to our rights plan, or
       any successor to our rights plan, and the declaration of a dividend of
       these rights in the future; and

     - payments under any guarantee.

     We anticipate that the revenue of each trust available for distribution to
you, as a holder of preferred securities, will be limited to payments under the
corresponding junior subordinated debentures in which the trust will invest the
proceeds from the issuance and sale of its preferred securities and its common
securities. See "Description of Junior Subordinated Debentures."

     If we do not make interest payments on the corresponding junior
subordinated debentures, the property trustee will not have funds available to
pay distributions on the related preferred securities. The payment of
distributions, if and to the extent the trust has funds legally available for
the payment of these distributions is guaranteed by us on a limited basis as set
forth under "Description of Guarantees."

     The trust will pay distributions on the preferred securities to you
provided you are entered in the register of the trust on the relevant record
dates. As long as the preferred securities remain in book-entry form, the record
date will be one business day prior to the relevant distribution date. If any
preferred securities are not in book-entry form, the record date for the
preferred securities will be the date 15 days prior to the relevant distribution
date.

REDEMPTION AND VOLUNTARY DISTRIBUTION

     REDEMPTION UPON REPAYMENT OR REDEMPTION OF THE CORRESPONDING JUNIOR
     SUBORDINATED DEBENTURES

     Upon the repayment or redemption, in whole or in part, of any corresponding
junior subordinated debentures, the property trustee must apply the proceeds
from that repayment or redemption to redeem a like amount of the preferred
securities and common securities of the related trust. This redemption must be
made upon not less than 30 nor more than 60 days' notice to you. Unless we state
otherwise in the applicable prospectus supplement, the redemption price will be
equal to 100% of the aggregate liquidation amount of the preferred and common
securities redeemed, plus accumulated and unpaid distributions on the preferred
and common securities redeemed up to but not including the date of redemption.
See "Description of Junior Subordinated Debentures -- Redemption."

     If less than all of any series of corresponding junior subordinated
debentures are repaid or redeemed, then the proceeds from the repayment or
redemption will be allocated to redeem a proportionate amount of each of the
preferred securities and the common securities. The amount of premium, if any,
paid by us upon the redemption of all or any part of any series of any
corresponding junior subordinated debentures repaid or redeemed will be
allocated proportionately to the redemption of the preferred securities and the
common securities.

     We must repay the principal of the corresponding junior subordinated
debentures when they are due. In addition, unless we state otherwise in the
applicable prospectus supplement, we may, at our option and at any time, redeem
any series of corresponding junior subordinated debentures

     - in whole or in part, subject to the conditions we describe under
       "Description of Junior Subordinated Debentures -- Redemption"; or

     - as we may otherwise specify in the applicable prospectus supplement.

                                        37


     When we use the term "like amount," we mean:

     - with respect to a redemption of any series of preferred securities,
       preferred securities having a liquidation amount equal to that portion of
       the principal amount of corresponding junior subordinated debentures to
       be contemporaneously redeemed, the proceeds of which will be used to pay
       the redemption price of the preferred securities; and

     - with respect to a distribution of corresponding junior subordinated
       debentures to you, as a holder of preferred securities in connection with
       a dissolution or liquidation of the related trust, corresponding junior
       subordinated debentures having a principal amount equal to the
       liquidation amount of your preferred securities.

     When we use the term "liquidation amount," we mean the stated amount of $25
per preferred security and common security.

     VOLUNTARY DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES

     Unless we provide otherwise in the applicable prospectus supplement, we may
elect, at any time, to terminate the trust and cause the corresponding junior
subordinated debentures to be distributed to you, as a holder of the preferred
securities, and us, as the holder of the common securities, in liquidation of
the trust.

     After the liquidation date fixed for any distribution of corresponding
junior subordinated debentures for any series of preferred securities:

     - the series of preferred securities will no longer be deemed to be
       outstanding;

     - DTC or its nominee, as the record holder of the series of preferred
       securities, will receive a registered global certificate or certificates
       representing the corresponding junior subordinated debentures to be
       delivered upon that distribution; and

     - any certificates representing the series of preferred securities not held
       by DTC or its nominee will be deemed to represent the corresponding
       junior subordinated debentures having a principal amount equal to the
       stated liquidation preference of the series of preferred securities, and
       bearing accrued and unpaid interest in an amount equal to the accrued and
       unpaid distributions on the series of preferred securities until you
       present the certificates to the administrative trustees or their agent
       for transfer or reissuance.

     We can make no assurance as to what the market prices would be for the
preferred securities or the corresponding junior subordinated debentures that
may be distributed to you in exchange for your preferred securities if a
dissolution and liquidation of a trust were to occur. Accordingly, the preferred
securities that you purchase, or the corresponding junior subordinated
debentures that you receive on dissolution and liquidation of a trust, may trade
at a discount to the price that you paid to purchase the preferred securities.

     REDEMPTION PROCEDURES

     The trust will redeem the preferred securities and common securities on
each redemption date at the redemption price with the applicable proceeds from
the contemporaneous redemption of the corresponding junior subordinated
debentures. The trust will make redemptions of the preferred securities and pay
the redemption price only to the extent that it has funds available for the
payment of the redemption price. See "-- Subordination of Common Securities."

     If a trust gives notice to you of redemption of your preferred securities,
then by 12:00 noon, New York City time, on the redemption date, to the extent
funds are available, the property trustee will irrevocably deposit with DTC
funds sufficient to pay the applicable redemption price and will give DTC
irrevocable instructions and authority to pay the redemption price to you. See
"-- Global Preferred Securities."

                                        38


     If the preferred securities are no longer in book-entry form, the trust, to
the extent funds are available, will irrevocably deposit with the paying agent
for the preferred securities funds sufficient to pay the applicable redemption
price to you and will give the paying agent irrevocable instructions and
authority to pay the redemption price to you upon surrender of your
certificates.

     The trust will pay any distributions payable on or prior to the redemption
date for any preferred securities called for redemption to you on the relevant
record dates for the distribution. If the trust has given notice of redemption
and has deposited the required funds, then upon the date of the deposit, all
your rights will cease, except your right to receive the redemption price,
without interest on that redemption price, and your preferred securities will
cease to be outstanding. If any date fixed for redemption of preferred
securities is not a business day, then the trust will pay the redemption price
on the next succeeding day which is a business day, and without any interest or
other payment on account of the delay. However, if the business day falls in the
next calendar year, the trust will make the payment on the immediately preceding
business day. If payment of the redemption price is improperly withheld or
refused and not paid either by the trust or by us pursuant to the guarantee as
described under "Description of Guarantees," distributions on the preferred
securities will continue to accrue at the then applicable rate, from the
redemption date originally established by the trust for the preferred securities
to the date the redemption price is actually paid. In this case the actual
payment date will be the date fixed for redemption for purposes of calculating
the redemption price.

     Subject to applicable law, including the United States federal securities
laws, we or our subsidiaries may at any time purchase outstanding preferred
securities by tender, in the open market or by private agreement.

     The trust will make payment of the redemption price on the preferred
securities and any distribution of corresponding junior subordinated debentures
to the applicable record holders as they appear on the register for the
preferred securities on the relevant record date. This date will generally be
one business day prior to the relevant redemption date or liquidation date.
However, if any preferred securities are not in book-entry form, the relevant
record date for the preferred securities will be the date 15 days prior to the
redemption date or liquidation date.

     If less than all of the preferred securities and common securities issued
by a trust are to be redeemed on a redemption date, then the aggregate
liquidation amount of the preferred securities and common securities to be
redeemed will be allocated proportionately among the preferred securities and
the common securities. The property trustee will select the particular preferred
securities to be redeemed on a proportionate basis not more than 60 days prior
to the redemption date from the outstanding preferred securities not previously
called for redemption, by any method that the property trustee deems fair and
appropriate. This method may provide for the selection for redemption of
portions, equal to $25 or an integral multiple of $25, of the liquidation amount
of preferred securities. The property trustee will promptly notify the trust
registrar in writing of the preferred securities selected for redemption and, in
the case of any preferred securities selected for partial redemption, the
liquidation amount of the preferred securities to be redeemed.

SUBORDINATION OF COMMON SECURITIES

     The trust will make payment of distributions, any additional amounts and
the redemption price on the preferred securities and common securities
proportionately based on the liquidation amount of the preferred securities and
common securities. However, if on any distribution date or redemption date a
debenture event of default exists, the trust will not make any payment on the
common securities unless payment in full in cash of all accumulated and unpaid
distributions, any additional amounts and the full amount of the redemption
price on all of the outstanding preferred securities of the trust, has been made
or provided for. The property trustee will apply all available funds first to
the payment in full in cash of all distributions on the preferred securities
then due and payable.

                                        39


     If any event of default resulting from a debenture event of default exists,
we, as holder of the common securities of the trust, will be deemed to have
waived any right to act with respect to the event of default under the trust
agreement until the effect of all those events of default with respect to the
preferred securities has been cured, waived or otherwise eliminated. Until any
events of default under the trust agreement with respect to the preferred
securities have been so cured, waived or otherwise eliminated, the property
trustee will act solely on your behalf, as a holder of the preferred securities,
and not on our behalf as holder of the common securities, and only you acting
with the other holders will have the right to direct the property trustee to act
on your behalf.

LIQUIDATION DISTRIBUTION UPON TERMINATION

     Each trust will automatically terminate upon expiration of its term or the
redemption of all of the preferred securities of the trust. In addition, we will
terminate the trust on the first to occur of:

     - our bankruptcy, dissolution or liquidation;


     - a tax event or an investment company event, as described in the trust
       agreement, or the trust is not or will not be taxed as a grantor trust
       but a tax event has not occurred, and written direction is given to the
       property trustee within 45 days of such event to terminate the trust;



     - the redemption of all of the preferred securities; and


     - the entry of an order for the dissolution of the trust by a court of
       competent jurisdiction.


     If an early termination occurs as described in the clauses above, the
trustees will liquidate the trust as expeditiously as the trustees determine to
be possible by distributing, after satisfaction of liabilities to creditors of
the trust as provided by applicable law, to the holders of the preferred
securities and common securities a like amount of corresponding junior
subordinated debentures. If the property trustee determines that this
distribution is not practical, you will be entitled to receive out of the assets
of the trust available for distribution, after satisfaction of liabilities to
creditors of the trust as provided by applicable law, an amount equal to the
aggregate of the liquidation amount plus accrued and unpaid distributions to the
date of payment. We refer to this liquidation amount in this prospectus as the
"liquidation distribution." If the trust can make the liquidation distribution
only in part because it has insufficient assets available to pay the full
aggregate liquidation distribution, then it will pay the amounts on a
proportionate basis. We, as the holder of the common securities, will be
entitled to receive distributions upon any liquidation proportionately with you,
and the other holders of the preferred securities, except that if an event
exists that constitutes an event of default under the corresponding series of
junior subordinated debentures, the preferred securities will have a priority
over the common securities. A supplemental indenture may provide that if an
early termination occurs as described in the third clause above, the
corresponding junior subordinated debentures may be subject to optional
redemption in whole, but not in part.


EVENTS OF DEFAULT; NOTICE

     Under the terms of the trust agreements, each of the following constitutes
an event of default for a series of preferred securities:


     - the occurrence of an event of default under the corresponding series of
       junior subordinated debentures (see "Description of Junior Subordinated
       Debentures -- Debenture Events of Default");


     - default by the property trustee in the payment of any distribution when
       it becomes due and payable, and continuation of that default for a period
       of 30 days;

     - default by the property trustee in the payment of any redemption price of
       the preferred securities or common securities when it becomes due and
       payable;

     - default in the performance, or breach, in any material respect, of any
       covenant or warranty of the trustees in the trust agreement, other than a
       covenant or warranty a default in the

                                        40


       performance of which or the breach of which is dealt with in the second
       and third clauses above, and continuation of the default or breach for a
       period of 60 days after there has been given to the defaulting trustee or
       trustees by the holders of at least 10% in aggregate liquidation amount
       of the outstanding preferred securities, a written notice specifying the
       default or breach and requiring it to be remedied and stating that the
       notice is a notice of default under such trust agreement; or

     - the bankruptcy or insolvency of the property trustee and our failure to
       appoint a successor property trustee within 60 days of that event.

     Within five business days after the occurrence of any event of default
actually known to the property trustee, the property trustee will transmit
notice of the event of default to you, the administrative trustees and us, as
depositor, unless the event of default has been cured or waived. We, as
depositor, and the administrative trustees are required to file annually with
the property trustee a certificate as to whether or not we are and they are in
compliance with all the conditions and covenants applicable to them and to us
under the trust agreement.


     If an event of default under the corresponding series of junior
subordinated debentures then exists, the preferred securities will have a
preference over the common securities upon termination of the trust. See
"-- Liquidation Distribution upon Termination."


     The existence of an event of default does not entitle you to accelerate the
maturity of the corresponding junior subordinated debentures.

MODIFICATION OF THE JUNIOR SUBORDINATED INDENTURE

     In the case of corresponding junior subordinated debentures, so long as any
of the related series of preferred securities remain outstanding:

     - no modification of the junior subordinated indenture may be made that
       adversely affects the holders of the preferred securities;

     - no termination of the junior subordinated indenture may occur; and


     - no waiver of any event of default or compliance with any covenant under
       the junior subordinated indenture with respect to the corresponding
       series of junior subordinated debentures may be effective,


without the prior consent of the holders of at least a majority of the aggregate
liquidation preference of the related preferred securities unless the principal
of, and premium, if any on, the corresponding junior subordinated debentures and
all accrued and unpaid interest on the corresponding junior subordinated
debentures have been paid in full and other conditions are satisfied.

REMOVAL OF TRUSTEES


     Unless an event of default under the corresponding series of junior
subordinated debentures exists, the holder of the common securities may remove
any trustee. If a debenture event of default exists, the holders of a majority
in liquidation amount of the outstanding preferred securities may remove the
property trustee and the Delaware trustee. In no event will you have the right
to vote to appoint, remove or replace the administrative trustees. These voting
rights are vested exclusively in us as the holder of the common securities. No
resignation or removal of a trustee and no appointment of a successor trustee
will be effective until the acceptance of appointment by the successor trustee
in accordance with the provisions of the trust agreement.


CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE

     Unless an event of default then exists, for the purpose of meeting the
legal requirements of the Trust Indenture Act or of any jurisdiction in which
any part of the trust property may be located, we, as the holder of the common
securities, and the administrative trustees will have power to

                                        41



appoint one or more persons either to act as a co-trustee, jointly with the
property trustee, of all or any part of the trust property, or to act as
separate trustee. These persons will have the powers provided in the instrument
of appointment, and we may vest in that person or persons any property, title,
right or power deemed necessary or desirable, subject to the provisions of the
trust agreement. If an event of default under the corresponding series of junior
subordinated debentures exists, the property trustee alone will have power to
make that appointment.


MERGER OR CONSOLIDATION OF TRUSTEES

     Any corporation into which the property trustee, the Delaware trustee or
any administrative trustee that is not a natural person may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the trustee is a party, or
any corporation succeeding to all or substantially all the corporate trust
business of the trustee, will be the successor of such trustee under the trust
agreements, provided that the corporation is otherwise qualified and eligible.

MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE TRUSTS

     A trust may not merge with or into, consolidate, amalgamate, or be replaced
by, or convey, transfer or lease its properties and assets substantially as an
entirety to any corporation or other body, except as described below.


     A trust may, at our request, with the consent of the administrative
trustees and without your consent, merge with or into, consolidate, amalgamate,
or be replaced by a trust organized under the laws of any state. However, the
following conditions must be satisfied:


     - the successor entity must either:

      - expressly assume all of the obligations of the trust relating to the
        preferred securities; or

      - substitute for the preferred securities other securities having
        substantially the same terms and the same ranking as the preferred
        securities;

     - we must expressly appoint a trustee of the successor entity possessing
       the same powers and duties as the property trustee as the holder of the
       corresponding junior subordinated debentures;

     - the successor securities must be listed upon notification of issuance, on
       any national securities exchange or other organization on which the
       preferred securities are then listed;


     - the merger, consolidation, amalgamation or replacement must not cause the
       preferred securities, including any successor securities, to be
       downgraded by any nationally recognized statistical rating organization;



     - the merger, consolidation, amalgamation or replacement must not adversely
       affect the rights, preferences and privileges of holders of the preferred
       securities, including any successor securities, in any material respect;


     - the successor entity must have a purpose identical to that of the trust;


     - prior to the merger, consolidation, amalgamation or replacement, we must
       have received an opinion from independent counsel to the trust
       experienced in such matters to the effect that:



      - the merger, consolidation, amalgamation or replacement, does not
        adversely affect the rights, preferences and privileges of holders of
        the preferred securities, including any successor securities, in any
        material respect; and



      - following the merger, consolidation, amalgamation or replacement,
        neither the trust nor the successor entity will be required to register
        as an investment company under the Investment Company Act; and

                                        42


     - we or any permitted successor or assignee must own all of the common
       securities of the successor entity and guarantee the obligations of such
       successor entity under the successor securities at least to the extent
       provided by the guarantee.


     However, a trust may not, except with the consent of holders of 100% in
liquidation amount of the preferred securities, consolidate, amalgamate, merge
with or into, or be replaced by any other entity or permit any other entity to
consolidate, amalgamate, merge with or into, or replace it if it would cause the
trust or the successor entity to be classified as other than a grantor trust for
federal income tax purposes.


VOTING RIGHTS; AMENDMENT OF TRUST AGREEMENT

     Except as provided below and under "Description of Guarantees-Amendments
and Assignment" and as otherwise required by law and the applicable trust
agreement, you will have no voting rights.

     We and the trustees may amend a trust agreement without your consent:

     - to cure any ambiguity, correct or supplement any provisions in the trust
       agreement which may be inconsistent with any other provision, or to make
       any other provisions with respect to matters or questions arising under
       the trust agreement, which are not inconsistent with the other provisions
       of the trust agreement; or

     - to modify, eliminate or add to any provisions of the trust agreement to
       the extent necessary to ensure that the trust will be classified for
       federal income tax purposes as a grantor trust at all times that any
       preferred securities and common securities are outstanding, or to ensure
       that the trust will not be required to register as an investment company
       under the Investment Company Act.

However, in the case of the first clause above, the action may not adversely
affect in any material respect the interests of the holders of the preferred
securities or our interests, as the holder of the common securities. Any
amendments of the trust agreement will become effective when notice is given to
you and us.

     We and the trustees may also amend a trust agreement with:

     - the consent of holders representing not less than a majority, based upon
       liquidation amounts, of the outstanding preferred securities and common
       securities; and

     - receipt by the trustees of an opinion of counsel to the effect that the
       amendment or the exercise of any power granted to the trustees under the
       amendment will not affect the status of the trust as a grantor trust for
       federal income tax purposes or its exemption from the status of an
       "investment company" under the Investment Company Act.

     Without both your and our consent a trust agreement may not be amended to:

     - change the amount or timing of any distribution on the preferred
       securities and common securities or otherwise adversely affect the amount
       of any distribution of the preferred securities and common securities as
       of a specified date; or

     - restrict your or our right to institute suit for the enforcement of any
       payment on or after that date.

     So long as any corresponding junior subordinated debentures are held by the
property trustee, the trustees may not:


     - direct the time, method and place of conducting any proceeding for any
       remedy available to the debenture trustee, or for executing any trust or
       power conferred on the debenture trustee with respect to the
       corresponding junior subordinated debentures;


                                        43



     - waive any past default that is waivable under specified sections of the
       junior subordinated indenture;


     - exercise any right to rescind or annul a declaration that the principal
       of all the junior subordinated debentures is due and payable; or

     - consent to any amendment, modification or termination of the junior
       subordinated indenture or the corresponding junior subordinated
       debentures, where that consent is required

without, in each case, obtaining the prior approval of the holders of a majority
in aggregate liquidation amount of all outstanding preferred securities.
However, where a consent under the junior subordinated indenture would require
the consent of each holder of corresponding junior subordinated debentures
affected by the consent, no consent may be given by the property trustee without
the prior consent of each holder of the related preferred securities.

     The trustees may not revoke any action previously authorized or approved by
a vote of the preferred securities except by subsequent vote of the holders of
the preferred securities. The property trustee will notify you of any notice of
default with respect to the corresponding junior subordinated debentures. In
addition to obtaining the approval of the holders of the preferred securities
prior to taking any of these actions, the trustees must obtain an opinion of
counsel experienced in these matters to the effect that the trust will not be
classified as a corporation or partnership for United States federal income tax
purposes on account of the action.

     Any required approval of holders of preferred securities may be given at a
meeting of holders of preferred securities convened for that purpose or through
a written consent. The property trustee will cause a notice of any meeting at
which you are entitled to vote, or of any matter upon which action by written
consent is to be taken, to be given to each holder of record of preferred
securities in the manner set forth in the trust agreement.

     Your vote or consent is not required for a trust to redeem and cancel the
preferred securities under the applicable trust agreement.

     Any preferred securities that are owned by us, the trustees or any of our
affiliates or any affiliate of the trustees, will, for purposes of a vote or
consent, be treated as if they were not outstanding.

GLOBAL PREFERRED SECURITIES

     Each trust may issue a series of preferred securities in the form of one or
more global preferred securities that will be deposited with a depositary
identified in a prospectus supplement. Unless otherwise stated in the applicable
prospectus supplement, the Depositary Trust Company, New York, New York, or DTC,
will act as depositary. The trusts will issue global preferred securities only
in fully registered form and in either temporary or permanent form. Unless it is
exchanged for individual preferred securities, a global preferred security may
not be transferred unless it is being transferred to certain nominees of the
depositary.

     We will describe the specific terms of the depositary arrangement in the
applicable prospectus supplement. We expect that the following provisions will
generally apply to these depositary arrangements.

     BENEFICIAL INTERESTS IN A GLOBAL PREFERRED SECURITY

     If a trust issues a global preferred security, the depositary for the
global preferred security or its nominee will credit on its book-entry
registration and transfer system the aggregate liquidation amounts of the
individual preferred securities represented by the global preferred securities
to the accounts of participants. The accounts will be designated by the dealers,
underwriters or agents for the preferred securities, or by us if the preferred
securities are offered and sold directly by the trust. Ownership of beneficial
interests in a global preferred security will be limited to participants
                                        44


or persons that may hold the trust interests through participants. Ownership and
transfers of beneficial interests in the global preferred security will be shown
on, and effected only through, records maintained by the applicable depositary
or its nominee, for interests of participants, and the records of participants,
for interests of persons who hold through participants. The laws of some states
may require that you take physical delivery of the securities in definitive
form. These limits and laws may impair your ability to transfer beneficial
interests in a global preferred security.

     So long as the depositary or its nominee is the registered owner of the
global preferred security, the depositary or nominee will be considered the sole
owner or holder of the preferred securities represented by the global preferred
security for all purposes under the trust agreement. Except as provided below,
you:

     - will not be entitled to have any of the individual preferred securities
       represented by the global preferred security registered in your name;

     - will not receive or be entitled to receive physical delivery of any
       preferred securities in definitive form; and

     - will not be considered the owner or holder of the preferred security
       under the trust agreement.

     PAYMENTS OF DISTRIBUTIONS

     The trust will pay distributions on global preferred securities to the
depositary that is the registered holder of the global security, or its nominee.
The depositary for the preferred securities will be solely responsible and
liable for all payments made on account of your beneficial ownership interests
in the global preferred security and for maintaining, supervising and reviewing
any records relating to your beneficial ownership interests.


     We expect that the depositary or its nominee, upon receipt of any payment
of liquidation amount, premium or distributions, immediately will credit
participants' accounts with amounts in proportion to their respective beneficial
interests in the aggregate liquidation amount of the global preferred security
as shown on the records of the depositary or its nominee. We also expect that
payments by participants to owners of beneficial interests in the global
preferred security held through those participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name."
These payments will be the responsibility of those participants.


     Further, the trust may specify that you may, on terms acceptable to us, the
property trustee and the depositary for the global preferred security, receive
definitive preferred securities in exchange for your beneficial interests in a
global preferred security, subject to any limitations described in the
prospectus supplement relating to the preferred securities. In that instance,
you will be entitled to physical delivery of definitive preferred securities
equal in liquidation amount to that beneficial interest and to have the
preferred securities registered in your name. Unless otherwise provided in the
applicable prospectus supplement, those definitive preferred securities will be
issued in denominations of $25 and integral multiples of $25.

PAYMENT AND PAYING AGENTS

     Unless otherwise provided in the applicable prospectus supplement, each
trust will make payments on the preferred securities to DTC, which will credit
the relevant accounts at DTC on the applicable distribution dates. However, if
any preferred securities are not held by DTC, the trust will make the payments
by check mailed to the address of the holder entitled to the payment as shown on
the register. Unless otherwise provided in the applicable prospectus supplement,
the paying agent will initially be the property trustee, together with any
co-paying agent chosen by the property trustee and acceptable to the
administrative trustees and us. The paying agent may resign as paying agent upon
30 days' written notice to the property trustees and us. If the property trustee
                                        45


ceases to be the paying agent, the administrative trustees will appoint a
successor to act as paying agent. The successor must be a bank or trust company
acceptable to the administrative trustees and us.

REGISTRAR AND TRANSFER AGENT

     Unless otherwise provided in the applicable prospectus supplement, the
property trustee will act as registrar and transfer agent for the preferred
securities.

     The trust will register transfers of preferred securities without charge,
but upon your payment of any tax or other governmental charges that may be
imposed in connection with any transfer or exchange. The trust will not be
required to register the transfer of its preferred securities after the
preferred securities have been called for redemption.

INFORMATION CONCERNING THE PROPERTY TRUSTEE

     The property trustee, unless an event of default then exists, will be
required to perform only those duties that are specifically set forth in the
applicable trust agreement. After an event of default, the property trustee must
exercise the same degree of care and skill as a prudent person would exercise or
use in the conduct of his or her own affairs. However, the property trustee is
under no obligation to exercise any of the powers vested in it by the trust
agreement at your request unless you offer reasonable indemnity against the
costs, expenses and liabilities that it might incur. If no event of default then
exists and the property trustee is required to decide between alternative causes
of action, construe ambiguous provisions in a trust agreement or is unsure of
the application of any provision of a trust agreement, and the matter is not one
on which holders are entitled under the trust agreement to vote, then the
property trustee will take such action as is directed by us. If it is not so
directed, the property trustee will take such action as it deems advisable and
in the best interests of the holders of the preferred securities and the holder
of the common securities and will have no liability except for its own bad
faith, negligence or willful misconduct.

MISCELLANEOUS


     Each trust agreement authorizes and directs the administrative trustees to
operate the trust in such a way that the trust will not be deemed to be an
investment company required to be registered under the Investment Company Act or
taxed as a corporation or partnership for federal income tax purposes, and in
such a way that the corresponding junior subordinated debentures will be treated
as our indebtedness for United States federal income tax purposes. We and the
administrative trustees are authorized to take any action, not inconsistent with
applicable law, the certificate of trust or the trust agreement, that we and the
administrative trustees determine in our discretion to be necessary or desirable
for these purposes, as long as the action does not materially adversely affect
the interests of the holders of the preferred securities.


     You have no preemptive or similar rights as a holder of preferred
securities. No trust may borrow money or issue debt or mortgage or pledge any of
its assets.

                                        46


                           DESCRIPTION OF GUARANTEES

     At the same time as the issuance by a trust of its preferred securities, we
will execute and deliver a guarantee for your benefit as a holder of the
preferred securities. Bank One Trust Company, N.A. will act as indenture trustee
under each guarantee for the purposes of compliance with the Trust Indenture
Act. Each guarantee will be qualified as an indenture under the Trust Indenture
Act.


     The following description of the terms of the guarantees is a summary. It
summarizes only those portions of the guarantees which we believe will be most
important to your decision to invest in the preferred securities. You should
keep in mind, however, that it is the guarantees, and not this summary, which
define your rights. There may be other provisions in the guarantees which are
also important to you. You should read each guarantee itself for a full
description of its terms. The form of the guarantees are filed as exhibits to
the registration statement that includes this prospectus. See "Where You Can
Find More Information" for information on how to obtain copies of the
guarantees. The terms of each guarantee will include those stated in the
applicable guarantee and those made part of the guarantee by reference to the
Trust Indenture Act. Each guarantee will be executed at the time the related
trust issues any preferred securities and will be filed with the SEC on a Form
8-K or by a post-effective amendment to the registration statement that includes
this prospectus. When we refer in this summary to preferred securities, we mean
the preferred securities issued by a trust to which a guarantee relates.


GENERAL TERMS OF THE GUARANTEES

     We will irrevocably agree to pay in full on a subordinated basis, to the
extent described below, the guarantee payments, as defined below, to you, as and
when due, regardless of any defense, right of set-off or counterclaim that the
trust may have or assert other than the defense of payment.

     The following payments, which we refer to in this prospectus as the
"guarantee payments," to the extent not paid by or on behalf of the related
trust, will be subject to the guarantees:

     - any accrued and unpaid distributions required to be paid to you on the
       related preferred securities, to the extent that the trust has funds
       available for the payments;


     - the redemption price, including all accrued and unpaid distributions to
       the date of redemption with respect to any preferred securities called
       for redemption by the trust, to the extent that the trust has funds
       available for the payments; or


     - upon a voluntary or involuntary dissolution, winding-up or liquidation of
       the trust, unless the corresponding junior subordinated debentures are
       distributed to you, the lesser of:

      - the liquidation distribution; and

      - the amount of assets of the trust remaining available for distribution
        to you.

     Our obligation to make a guarantee payment may be satisfied by us directly
paying to you the required amounts or by causing the trust to pay the amounts to
you.

     Each guarantee will be an irrevocable guarantee on a subordinated basis of
the related trust obligations under the preferred securities, but will apply
only to the extent that the related trust has funds sufficient to make the
payments. It is not a guarantee of collection.

     If we do not make interest payments on the corresponding junior
subordinated debentures held by the trust, we expect that the trust will not pay
distributions on the preferred securities and will not have funds legally
available for those payments. The guarantees will rank subordinate and junior in
right of payment to all of our debt other than debt which ranks equally with or
junior to the guarantees. See "-- Status of the Guarantees."

                                        47


     As a non-operating holding company, most of our operating assets and the
assets of our consolidated subsidiaries are owned by our subsidiaries. We rely
primarily on dividends from our subsidiaries to meet our obligations for payment
of principal and interest on our outstanding debt obligations and corporate
expenses. Accordingly, our obligations under the guarantees will be effectively
subordinated to all existing and future liabilities of our subsidiaries. You
should rely only on our assets for payments we owe. The payment of dividends by
our insurance company subsidiaries may be restricted by state insurance laws and
regulations as administered by state insurance departments. See "The Chubb
Corporation."

     Unless we state otherwise in the applicable prospectus supplement, the
guarantees do not limit the amount of secured or unsecured debt that we may
incur. We expect from time to time to incur additional senior debt.

     We have, through the guarantees, the trust agreements, the junior
subordinated debentures, the junior subordinated indenture and related expense
agreements, taken together, fully, irrevocably and unconditionally guaranteed
all of the obligations of the trusts under the preferred securities. No single
document standing alone or operating in conjunction with fewer than all of the
other documents constitutes a guarantee. It is only the combined operation of
these documents that has the effect of providing a full, irrevocable and
unconditional guarantee of the obligations of the trust under the preferred
securities. See "Relationship Among the Preferred Securities, the Corresponding
Junior Subordinated Debentures and the Guarantees."

STATUS OF THE GUARANTEES


     The guarantees will constitute unsecured obligations of Chubb and will rank
subordinate and junior in right of payment to all "senior indebtedness" of
Chubb. Senior indebtedness for this purpose has the same meaning as for the
junior subordinated debentures.


     Unless we state otherwise in the applicable prospectus supplement, the
guarantee of a series of preferred securities will rank equally with the
guarantees relating to all other series of preferred securities that we may
issue. A guarantee will constitute a guarantee of payment and not of collection,
which means that the guaranteed party may institute a legal proceeding directly
against us to enforce its rights under the guarantee without first instituting a
legal proceeding against the trust, the guarantee trustee or any other person or
entity. The property trustee of the related trust will hold the guarantees for
your benefit. The guarantees will not be discharged except by payment of the
guarantee payments in full to the extent not paid by the trust or upon
distribution of the corresponding junior subordinated debentures to you.

AMENDMENTS AND ASSIGNMENT


     We may not amend a guarantee without the prior approval of the holders of
not less than a majority of the aggregate liquidation amount of the outstanding
related preferred securities, except for any changes which do not materially
adversely affect the rights of the holders of the preferred securities, in which
case no vote will be required. The manner of obtaining any approval will be as
set forth under "Description of Preferred Securities -- Voting Rights; Amendment
of Trust Agreement."


     All guarantees and agreements contained in a guarantee will bind our
successors, assigns, receivers, trustees and representatives and will inure to
the benefit of the holders of the related preferred securities then outstanding.

EVENTS OF DEFAULT

     An event of default under a guarantee will occur when we fail to perform
any of our payment or other obligations under the guarantee. The holders of not
less than a majority in aggregate liquidation amount of the related preferred
securities have the right to direct the time, method and

                                        48


place of conducting any proceeding for any remedy available to the guarantee
trustee under the guarantee or to direct the exercise of any trust or power
conferred upon the guarantee trustee under the guarantee.

     You may institute a legal proceeding directly against us to enforce your
rights under a guarantee without first instituting a legal proceeding against
the trust, the guarantee trustee or any other person or entity.

     We, as guarantor, are required to file annually with each guarantee trustee
a certificate as to whether or not we are in compliance with all the conditions
and covenants applicable to us under the guarantee.

INFORMATION CONCERNING THE GUARANTEE TRUSTEE

     The guarantee trustee, unless a default by us in the performance of the
guarantee then exists, is required to perform only those duties that are
specifically set forth in the guarantee. After a default under the guarantee,
the guarantee trustee must exercise the same degree of care and skill as a
prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs. However, the guarantee trustee is under no obligation to
exercise any of the powers vested in it by the guarantee at your request unless
you offer reasonable indemnity against the costs, expenses and liabilities that
it might incur.

TERMINATION OF THE GUARANTEES

     Each guarantee will terminate and be of no further force and effect upon:

     - full payment of the redemption price of the related preferred securities;

     - full payment of the amounts payable upon liquidation of the related
       trust; or

     - the distribution of corresponding junior subordinated debentures to the
       holders in exchange for the related preferred securities.

     The guarantee will continue to be effective or will be reinstated if at any
time you must restore payment of any sums paid under the preferred securities or
the guarantees.

GOVERNING LAW

     The guarantees will be governed by and construed in accordance with the
laws of the State of New York.

EXPENSE AGREEMENTS

     We will enter into an expense agreement with each trust. Under each expense
agreement, we will irrevocably and unconditionally guarantee to each person or
entity to whom the relevant trust becomes indebted or liable, the full payment
of any costs, expenses or liabilities of the trust, other than obligations of
the trust to pay to you the amounts due to you under the terms of the preferred
securities.

                                        49


          DESCRIPTION OF CORRESPONDING JUNIOR SUBORDINATED DEBENTURES

     The corresponding junior subordinated debentures are to be issued in one or
more series under the junior subordinated indenture, with terms corresponding to
the terms of the related preferred securities. The terms of the junior
subordinated debentures and the junior subordinated indenture are generally
described under "Description of Junior Subordinated Debentures." The following
summary describes the terms of the corresponding junior subordinated debentures
and the junior subordinated indenture that will apply in the specific case of
our issuing junior subordinated debentures to a trust in the context of that
trust issuing related preferred securities to you.

     The following description of the terms of the corresponding junior
subordinated debentures and the junior subordinated indenture is a summary. It
summarizes only those portions of the junior subordinated indenture which we
believe will be most important to your decision to invest in the preferred
securities. You should keep in mind, however, that it is the junior subordinated
indenture, and not this summary, which defines your rights. There may be other
provisions in the junior subordinated indenture which are also important to you.
You should read the form of the junior subordinated indenture itself for a full
description of its terms. The junior subordinated indenture is filed as an
exhibit to the registration statement that includes this prospectus. See "Where
You Can Find More Information" for information on how to obtain a copy of the
junior subordinated indenture.

GENERAL TERMS OF THE CORRESPONDING JUNIOR SUBORDINATED DEBENTURES

     At the same time a trust issues preferred securities, the trust will invest
the proceeds from the sale of the preferred securities and the consideration
paid by us for the common securities in a series of corresponding junior
subordinated debentures issued by us to the trust. Each series of corresponding
junior subordinated debentures will be in the principal amount equal to the
aggregate stated liquidation amount of the related preferred securities plus our
investment in the common securities and, unless we state otherwise in the
applicable prospectus supplement, will rank equally with all other series of
corresponding junior subordinated debentures. The corresponding junior
subordinated debentures will be unsecured and subordinate and junior in right of
payment to the extent and in the manner set forth in the junior subordinated
indenture to all our senior debt. See "Description of Junior Subordinated
Debentures -- Subordination" and the prospectus supplement relating to any
offering of related preferred securities.

REDEMPTION


     Unless we state otherwise in the applicable prospectus supplement, we may,
at our option and at any time, redeem any series of corresponding junior
subordinated debentures, in whole or in part, at a redemption price equal to
100% of the principal amount plus accrued and unpaid interest to the redemption
date. We may redeem corresponding junior subordinated debentures in
denominations larger than $25 but only in integral multiples of $25.



     We will mail notice of any redemption of your junior subordinated
debentures at least 30 days but not more than 60 days before the redemption date
to you at your registered address. Unless we default in payment of the
redemption price, on and after the redemption date interest will cease to accrue
on the debt securities or the portions called for redemption.



     For so long as the applicable trust is the holder of all the outstanding
series of corresponding junior subordinated debentures, the trust will use the
proceeds of any redemption to redeem the corresponding preferred securities. We
may not redeem a series of corresponding junior subordinated debentures in part
unless all accrued and unpaid interest has been paid in full on all outstanding
corresponding junior subordinated debentures of the series for all interest
periods terminating on or prior to the redemption date.


                                        50


COVENANTS OF THE CHUBB CORPORATION

     We will covenant in the junior subordinated indenture for each series of
corresponding junior subordinated debentures that we will pay additional sums to
the trust if:

     - the trust that has issued the corresponding series of preferred
       securities and common securities is the holder of all of the
       corresponding junior subordinated debentures;


     - a tax event, as defined therein, exists; and


     - we have not redeemed the corresponding junior subordinated debentures or
       terminated the trust.

     We will also covenant, for each series of corresponding junior subordinated
debentures, that we and our subsidiaries will not:

     - declare or pay any dividends or distributions on, or redeem, purchase,
       acquire, or make a liquidation payment on any of our capital stock; or


     - make any payment of principal, interest or premium, if any, on or repay,
       repurchase or redeem any debt securities, including other corresponding
       junior subordinated debentures, that rank equally with or junior in
       interest to the corresponding junior subordinated debentures or make any
       related guarantee payments,


other than:

     - dividends or distributions in our common stock;

     - redemptions or purchases of any rights pursuant to our rights plan, or
       any successor to our rights plan, and the declaration of a dividend of
       these rights in the future; and

     - payments under any guarantee of preferred securities,

if at that time:

     - there has occurred any event of which we have actual knowledge that with
       the giving of notice or the lapse of time, or both, would constitute an
       event of default under the junior subordinated indenture for that series
       of corresponding junior subordinated debentures which we have not taken
       reasonable steps to cure;

     - we are in default on our payment of any obligations under the related
       guarantee; or

     - we have given notice of our selection of an extension period as provided
       in the junior subordinated indenture for that series of corresponding
       junior subordinated debentures and have not rescinded that notice, or the
       extension period, or any extension, is continuing.

     We will also covenant, for each series of corresponding junior subordinated
debentures:

     - to maintain, by ourselves or our permitted successors, directly or
       indirectly 100% ownership of the common securities of the trust to which
       corresponding junior subordinated debentures have been issued;

     - not to voluntarily terminate, wind-up or liquidate any trust, except in
       connection with a distribution of corresponding junior subordinated
       debentures to you in liquidation of the trust, or in connection with
       mergers, consolidations or amalgamations permitted by the related trust
       agreement; and

     - to use our reasonable efforts, consistent with the terms and provisions
       of the related trust agreement, to cause the trust to remain a statutory
       trust and not to be classified as an association taxable as a corporation
       for United States federal income tax purposes.

     When we use the term "additional sums," we mean the additional amounts that
may be necessary in order that the amount of distributions then due and payable
by a trust on its
                                        51


outstanding preferred securities and common securities will not be reduced as a
result of any additional taxes, duties and other governmental charges to which
the trust has become subject as a result of a tax event.

RIGHTS OF PREFERRED SECURITYHOLDERS


     If a debenture event of default is attributable to our failure to pay
interest or principal on the corresponding junior subordinated debentures on the
date the interest or principal is payable, you, as a holder of related preferred
securities may institute a legal proceeding directly against us, which we refer
to in this prospectus as a direct action, for enforcement of payment to you of
the principal of or interest on the corresponding junior subordinated debentures
having a principal amount equal to the aggregate liquidation preference of your
related preferred securities.


     We may not amend the junior subordinated indenture to remove the right to
bring a direct action without the prior written consent of the holders of all of
the related preferred securities. If the right to bring a direct action is
removed, the applicable issue may become subject to the reporting obligations
under the Securities Exchange Act of 1934. We have the right under the junior
subordinated indenture to set-off any payment made to you as a holder of
preferred securities by us in connection with a direct action.


     If an event of default under the junior subordinated indenture with respect
to an outstanding series of junior subordinated debentures occurs and is
continuing, and if the debenture trustee or the holders of not less than 25% in
aggregate principal amount of the outstanding junior subordinated debentures of
that series fail to declare the principal amount of all of the junior
subordinated debentures of that series to be due and payable immediately, the
holders of 25% in aggregate liquidation amount of the related series of
preferred securities may by written notice thereof to us and to the debenture
trustee declare the principal amount of the junior subordinated debentures of
that series to be due and payable.



     You will not be able to exercise directly any remedies other than those
described in the preceding three paragraphs available to holders of a series of
the junior subordinated debentures unless there has been an event of default
under the corresponding trust agreement.


DISTRIBUTION OF THE CORRESPONDING JUNIOR SUBORDINATED DEBENTURES

     If provided in the applicable prospectus supplement, we will have the right
to extend or shorten the maturity of any series of corresponding junior
subordinated debentures at the time that we exercise our right to elect to
terminate the related trust and cause the corresponding junior subordinated
debentures to be distributed to the holders of the preferred securities and
common securities in liquidation of the trust.

                                        52


         RELATIONSHIP AMONG THE PREFERRED SECURITIES, THE CORRESPONDING
               JUNIOR SUBORDINATED DEBENTURES AND THE GUARANTEES

     As long as payments of interest and other payments are made when due on
each series of corresponding junior subordinated debentures, these payments will
be sufficient to cover distributions and other payments due on the related
preferred securities, primarily because:

     - the aggregate principal amount of each series of corresponding junior
       subordinated debentures will be equal to the sum of the aggregate stated
       liquidation amount of the corresponding preferred securities and
       corresponding common securities;

     - the interest rate and interest and other payment dates on each series of
       corresponding junior subordinated debentures will match the distribution
       rate and distribution and other payment dates for the corresponding
       preferred securities;

     - we will pay for all and any costs, expenses and liabilities of the trust
       except the obligations of the trust to holders of its preferred
       securities under the preferred securities; and

     - each trust agreement further provides that the trust will not engage in
       any activity that is not consistent with the limited purposes of the
       trust.

     We will irrevocably guarantee payments of distributions and other amounts
due on the preferred securities, to the extent the trust has funds available for
the payment of such distributions, as set forth under "Description of
Guarantees."

     Taken together, our obligations under each series of junior subordinated
debentures, the junior subordinated indenture, the related trust agreement, the
related expense agreement and the related guarantee provide a full, irrevocable
and unconditional guarantee by us of payments of distributions and other amounts
due on the related series of preferred securities. No single document standing
alone or operating in conjunction with fewer than all of the other documents
constitutes the guarantee. It is only the combined operation of these documents
that has the effect of providing a full, irrevocable and unconditional guarantee
of the obligations of the trust under the preferred securities. If and to the
extent that we do not make payments on any series of corresponding junior
subordinated debentures, the related trust will not pay distributions or other
amounts due on its preferred securities.

     Notwithstanding anything to the contrary in the junior subordinated
indenture, we have the right to set-off any payment we are otherwise required to
make under the junior subordinated indenture with and to the extent we have made
or are making a payment under the related guarantee.

     You may institute a legal proceeding directly against us to enforce your
rights under the related guarantee without first instituting a legal proceeding
against the guarantee trustee, the related trust or any other person or entity.

     The preferred securities of each trust evidence your rights to the benefits
of the trust. Each trust exists for the sole purpose of issuing its preferred
securities and common securities, investing the proceeds from the sale of such
securities in corresponding junior subordinated debentures and related purposes.

     A principal difference between your rights as a holder of a preferred
security and the rights of a holder of a corresponding junior subordinated
debenture is that a holder of a corresponding junior subordinated debenture will
accrue, and, subject to the permissible extension of the interest period, is
entitled to receive, interest on the principal amount of corresponding junior
subordinated debentures held, while you are only entitled to receive
distributions if and to the extent the trust has funds available for the payment
of those distributions.

     Upon any voluntary or involuntary termination, winding-up or liquidation of
any trust involving the liquidation of the corresponding junior subordinated
debentures, you will be entitled to
                                        53


receive, out of assets held by the trust, the liquidation distribution in cash.
See "Description of Preferred Securities -- Liquidation Distribution upon
Termination."


     Upon any voluntary or involuntary liquidation or bankruptcy of Chubb, the
property trustee, as holder of the corresponding junior subordinated debentures,
would be a subordinated creditor. In this case, the property trustee would be
subordinated in right of payment to all senior indebtedness of Chubb, but
entitled to receive payment in full of principal and interest, before any of our
stockholders receive payments or distributions. Since we are the guarantor under
each guarantee and have agreed to pay for all costs, expenses and liabilities of
each trust, your position as a holder of the preferred securities and the
position of a holder of the corresponding junior subordinated debentures
relative to other creditors and to our stockholders in the event of liquidation
or bankruptcy of our company would be substantially the same.



     A default or event of default under any senior indebtedness of Chubb would
not constitute a default or event of default under the junior subordinated
indenture. However, in the event of payment defaults under, or acceleration of,
senior indebtedness, the subordination provisions of the junior subordinated
indenture provide that we may not make payments on the corresponding junior
subordinated debentures until the senior indebtedness has been paid in full or
any payment default under the senior indebtedness has been cured or waived. Our
failure to make required payments on any series of corresponding junior
subordinated debentures would constitute an event of default under the junior
subordinated indenture.


                                        54


                              PLAN OF DISTRIBUTION

     We may sell the securities offered by this prospectus through agents,
underwriters or dealers, or directly to purchasers.


     We may use agents who we designate to solicit offers to purchase the
securities.


     - We will name any agent involved in offering or selling securities, and
       disclose any commissions that we will pay to the agent, in the applicable
       prospectus supplement.

     - Unless we indicate otherwise in the applicable prospectus supplement, our
       agents will act on a best efforts basis for the period of their
       appointment.

     - Our agents may be deemed to be underwriters under the Securities Act of
       1933, as amended, of any of the securities that they offer or sell.

     We may use an underwriter or underwriters in the offer or sale of our
securities.

     - If we use an underwriter or underwriters, we will execute an underwriting
       agreement with the underwriter or underwriters at the time that we reach
       an agreement for the sale of the securities.

     - We will include the names of the specific managing underwriter or
       underwriters, as well as the names of any other underwriters, and the
       terms of the transactions, including the compensation the underwriters
       and dealers will receive, in the applicable prospectus supplement.

     - The underwriters will use the applicable prospectus supplement to sell
       the securities.

     We may use a dealer to sell the securities.

     - If we use a dealer, we, as principal, will sell the securities to the

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Chubb Corporation is organized under the laws of the State of New
Jersey. The New Jersey Business Corporation Act, as amended (the "NJBCA"),
provides that a New Jersey corporation has the power generally to indemnify its
directors, officers, employees and other agents against expenses and liabilities
in connection with any proceeding involving such person by reason of his or her
being or having been a corporate agent, other than a proceeding by or in the
right of the corporation, if such person acted in good faith and in a manner he
or she reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal proceeding, such person had no
reasonable cause to believe his or her conduct was unlawful. In the case of an
action brought by or in the right of the corporation, indemnification of
directors, officers, employees and other agents against expenses is permitted if
such person acted in good faith and in a manner he or she reasonably believed to
be in or not opposed to the best interests of the corporation; however, no
indemnification is permitted in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation,
unless and only to the extent that the New Jersey Superior Court, or the court
in which such proceeding was brought, shall determine upon application that
despite the adjudication of liability, but in view of all the circumstances of
the case, such person is fairly and reasonably entitled to such indemnification.
Expenses incurred by a director, officer, employee or other agent in connection
with a proceeding may be, under certain circumstances, paid by the corporation
in advance of the final disposition of the proceeding as authorized by the board
of directors. The power to indemnify and advance expenses under the NJBCA does
not exclude other rights to which a director, officer, employee or other agent
of the corporation may be entitled to under the certificate of incorporation,
by-laws, agreement, vote of stockholders, or otherwise, provided that no
indemnification is permitted to be made to or on behalf of such person if a
judgment or other final adjudication adverse to such person establishes that his
or her acts or omissions were in breach of his or her duty of loyalty to the
corporation or its shareholders, were not in good faith or involved a violation
of the law, or resulted in the receipt by such person of an improper personal
benefit.

     Under the NJBCA, a New Jersey corporation has the power to purchase and
maintain insurance on behalf of any director, officer, employee or other agent
against any expenses incurred in any proceeding and any liabilities asserted
against him or her by reason of his or her being or having been a corporate
agent, whether or not the corporation has the power to indemnify him or her
against such expenses and liabilities under the NJBCA. All of the foregoing
powers of
                                       II-1


indemnification granted to a New Jersey corporation may be exercised by such
corporation notwithstanding the absence of any provision in its certificate of
incorporation or by-laws authorizing the exercise of such powers. However, a New
Jersey corporation may, with certain limitations, provide in its certificate of
incorporation that a director or officer shall not be personally liable, or
shall be liable only to the extent therein provided, to the corporation or its
shareholders for damages for breach of a duty owed to the corporation or its
shareholders.

     Reference is made to Sections 14A:3-5 and 14A:2-7(3) of the NJBCA in
connection with the above summary of indemnification, insurance and limitation
of liability.

     Article XII of the Restated Certificate of Incorporation of Chubb reads as
follows:

TWELFTH:

     SECTION A.  A Director or Officer of the Corporation shall not be
personally liable to the Corporation or its stockholders for damages for breach
of any duty owed to the Corporation or its stockholders, except for liability
for any breach of duty based upon an act or omission (i) in breach of such
Director's or Officer's duty of loyalty to the Corporation or stockholders, (ii)
not in good faith or involving a knowing violation of law or (iii) resulting in
receipt by such Director or Officer of an improper personal benefit. The
provisions of this section shall be effective as and to the fullest extent that,
in whole or in part, they shall be authorized or permitted by the laws of the
State of New Jersey. No repeal or modification of the foregoing provisions of
this Section A nor, to the fullest extent permitted by law, any modification of
law shall adversely affect any right or protection of a Director or Officer of
the Corporation which exists at the time of such repeal or modification.

     SECTION B.

     1.  As used in this Section B:

          (a) "corporate agent" means any person who is or was a director,
     officer, or employee of the Corporation and any person who is or was
     director, officer, trustee or employee of any other enterprise, serving, or
     continuing to serve, as such at the written request of the Corporation,
     signed by the Chairman or the President or pursuant to a resolution of the
     Board of Directors, or the legal representative of any such person;

          (b) "other enterprise" means any domestic or foreign corporation,
     other than the Corporation, and any partnership, joint venture, sole
     proprietorship, trust, employee benefit plan or other enterprise, whether
     or not for profit, served by a corporate agent;

          (c) "expenses" means reasonable costs, disbursements and counsel fees;

          (d) "liabilities" means amounts paid or incurred in satisfaction of
     settlements, judgments, fines and penalties;

          (e) "proceeding" means any pending, threatened or completed civil,
     criminal, administrative or arbitrative action, suit or proceeding, and any
     appeal therein and any inquiry or investigation which could lead to such
     action, suit or proceeding, and shall include any proceeding as so defined
     existing at or before, and any proceedings relating to facts occurring or
     circumstances existing at or before, the adoption of this Section B.

     2.  Each corporate agent shall be indemnified by the Corporation against
his expenses and liabilities in connection with any proceeding involving the
corporate agent by reason of his having been such corporate agent to the fullest
extent permitted by applicable law as the same exists or may hereafter be
amended or modified. The right to indemnification conferred by this paragraph 2
shall also include the right to be paid by the Corporation the expenses incurred
in connection with any such proceeding in advance of its final disposition to
the fullest extent authorized by applicable law as the same exists or may
hereafter be amended or modified. The right to indemnification conferred in this
paragraph 2 shall be a contract right.
                                       II-2


     3.  The Corporation may purchase and maintain insurance on behalf of any
corporate agent against any expenses incurred in any proceedings and any
liabilities asserted against him by reason of his having been a corporate agent,
whether or not the Corporation would have the power to indemnify him against
such expenses and liabilities under applicable law as the same exists or may
hereafter be amended or modified. The Corporation may purchase such insurance
from, or such insurance may be reinsured in whole or in part by, an insurer
owned by or otherwise affiliated with the Corporation, whether or not such
insurer does business with other insureds.

     The rights and authority conferred in this Section B shall not exclude any
other right to which any person may be entitled under this Certificate of
Incorporation, the By-Laws, any agreement, vote of stockholders or otherwise. No
repeal or modification of the foregoing provisions of this Section B nor, to the
fullest extent permitted by law, any modification of law, shall adversely affect
any right or protection of a corporate agent which exists at the time of such
repeal or modification.

     Chubb is insured against liabilities which it may incur by reason of
Article XII of Chubb's Restated Certificate of Incorporation. In addition,
directors and officers of Chubb are insured at the expense of Chubb against
certain liabilities which might arise out of their service and not be subject to
indemnification.

ITEM 17.  UNDERTAKINGS.

     (a) Rule 415 Offering.

     Each undersigned registrant hereby undertakes:

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

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

                                       II-5


             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;

     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
     the information required to be included in a post-effective amendment by
     those paragraphs is contained in periodic reports filed with or furnished
     to the Commission by such registrant pursuant to section 13 or section
     15(d) of the Securities Exchange Act of 1934 that are incorporated by
     reference in the registration statement.

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

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

     (b) Filings Incorporating Subsequent Exchange Act Documents by Reference.

     Each undersigned registrant hereby undertakes that, for purpose of
determining any liability under the Securities Act of 1933, each filing of such
registrant's annual report pursuant to Section 13(a) or 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 time shall be deemed to be
the initial bona fide offering thereof.

     (c) Acceleration of Effectiveness.

     Insofar as indemnifications for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrants pursuant to the foregoing provisions, or otherwise, the
registrants have been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by a registrant of expenses
incurred or paid by a director, officer or controlling person, if any, of such
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, such registrant 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 whether such

                                       II-6


indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

     (d) Equity Offerings of nonreporting registrants.

     Each undersigned registrant that is not a reporting company under the
Securities Exchange Act of 1934 hereby undertakes to provide to the underwriter
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriter to
permit prompt delivery to each purchaser.


     (e)  Rule 430A



     Each undersigned registrant hereby undertakes that:



          (1)  For purposes of determining any liability under the Securities
     Act of 1933, the information omitted from the form of prospectus filed as
     part of this registration statement in reliance upon Rule 430A and
     contained in a 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.



          (2)  For the purpose of determining any liability under the Securities
     Act of 1933, 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.



     (f)  Qualification of Trust Indentures for Delayed Offerings.


     Each undersigned registrant hereby undertakes to file an application for
the purpose of determining eligibility of the trustee to act under subsection
(a) of section 310 of the Trust Indenture Act ("Act") in accordance with the
rules and regulations prescribed by the Commission under section 305(b)(2) of
the Act.

                                       II-7
