beneficial interests in the assets of the Trust. The Trust exists for the
exclusive purposes of issuing and selling the Trust Securities and investing the
proceeds thereof in an equivalent principal amount of         % Subordinated
Deferrable Interest Debentures due         ,         of the Company (for the
purpose of this Prospectus Supplement, the "Subordinated Debentures"). The
Subordinated Debentures will be unsecured obligations of the Company and will be
subordinate and junior in right of payment to certain other indebtedness of the
Company, as described herein. Upon an event of default under the Declaration (as
defined herein), the holders of the Preferred Securities will have a preference
over the holders of the Common Securities with respect to payments in respect of
distributions and payments upon liquidation, redemption and otherwise.
 
    Holders of the Preferred Securities are entitled to receive cumulative cash
distributions at an annual rate of     % of the liquidation amount of $25 per
Preferred Security, accruing from         , 1998 and payable quarterly in
arrears on      ,      ,         and      of each year, commencing         ,
1998 ("distributions"). The distribution payable on      , 1998, which will be
calculated at the above rate and based on a period that is shorter than a full
quarter, will be in the amount of $     per Preferred Security. The distribution
rate and the distribution and other payment dates for the Preferred Securities
will correspond to the interest rate and interest and other payment dates on the
Subordinated Debentures, which will be the sole assets of the Trust. As a
result, if principal or interest is not paid on the Subordinated Debentures, no
amounts will be paid on the Preferred Securities. The payment of distributions
out of moneys held by the Trust, and payments on liquidation of the Trust or the
redemption of Preferred Securities, as set forth below, are guaranteed by the
Company (the "Preferred Securities Guarantee") if and to the extent the Trust
has funds available therefor. The Company's obligations under the Preferred
Securities Guarantee, taken together with its other obligations described
herein, constitute a full and unconditional guarantee by the Company of payments
due on the Preferred Securities. See "Effect of Obligations Under the
Subordinated Debentures and the Preferred Securities Guarantee" and "Description
of the Preferred Securities Guarantee." The obligations of the Company under the
Preferred Securities Guarantee are subordinate and junior in right of payment to
all other liabilities of the Company and will rank PARI PASSU with the most
senior preferred stock issued by the Company from time to time and with any
guarantee that may be entered into by the Company in respect of any preferred
stock of any subsidiary or affiliate of the Company. If the Company does not
make principal or interest payments on the Subordinated Debentures, the Trust
will not have sufficient funds to redeem or make distributions on the Preferred
Securities, in which event the Preferred Securities Guarantee will not apply to
such redemptions or distributions until the Trust has sufficient funds available
therefor. The obligations of the Company under the Subordinated Debentures are
subordinate and junior in right of payment to all present and future Senior
Indebtedness (as defined herein) of the Company. The Senior Indebtedness of the
Company aggregated approximately $1.6 billion at April 30, 1998. As of such
date, the indebtedness ranking PARI PASSU with the Subordinated Debentures
aggregated approximately $300 million. In addition, because the Company is a
holding company, its obligations under the Preferred Securities Guarantee and
the Subordinated Debentures will be effectively subordinated to all existing and
future liabilities of the Company's subsidiaries. At April 30, 1998, the
subsidiaries of the Company had total indebtedness outstanding and other
liabilities of approximately $187 million (excluding, in each case, indebtedness
and other liabilities owed to the Company and other affiliates, guaranteed
indebtedness of subsidiaries that is included in Senior Indebtedness, deferred
income taxes and other deferred credits).
 
    The Company has the right to defer payments of interest on the Subordinated
Debentures by extending the interest payment period on the Subordinated
Debentures, at any time, for up to   consecutive quarters (each, an "Extension
Period"); PROVIDED, HOWEVER, that no Extension Period may extend beyond the
maturity of the Subordinated Debentures. If interest payments are so deferred,
distributions on the Preferred Securities will also be deferred. Despite such
deferral, during an Extension Period distributions will continue to accrue with
interest thereon at an annual rate of    % per annum,
 
                                      S-2

compounded quarterly (to the extent permitted by applicable law), and holders of
Preferred Securities will be required to include deferred interest income in
their gross income for United States federal income tax purposes in advance of
receipt of the cash interest payments attributable to such deferred income.
There could be multiple Extension Periods of varying lengths throughout the term
of the Subordinated Debentures. See "Description of the Subordinated
Debentures--Option to Extend Interest Payment Period," "Risk Factors--Option to
Extend Interest Payment Period," and "Certain Federal Income Tax
Consequences--Original Issue Discount, Premium and Market Discount." In the
event of any such deferral, the holders of the Preferred Securities do not have
the right to appoint a special representative or trustee or otherwise act to
protect their interests.
 
    The Subordinated Debentures are redeemable by the Company (in whole or in
part) from time to time, on or after       ,       , or at any time in certain
circumstances upon the occurrence of a Tax Event (as defined herein) at 100% of
the principal amount of the Subordinated Debentures to be redeemed plus accrued
and unpaid interest thereon to the date fixed for redemption. If the Company
redeems Subordinated Debentures, the Trust must redeem Trust Securities on a pro
rata basis having an aggregate liquidation amount equal to the aggregate
principal amount of the Subordinated Debentures so redeemed at $25 per Trust
Security plus accrued and unpaid distributions thereon (the "Redemption Price")
to the date fixed for redemption. See "Description of the Preferred
Securities--Mandatory and Optional Redemption." The Trust Securities will be
redeemed at the Redemption Price upon maturity of the Subordinated Debentures.
The Subordinated Debentures mature on      ,      . In addition, upon the
occurrence of a Special Event (as defined herein) arising from a change in law
or a change in legal interpretation, unless the Subordinated Debentures are
redeemed in the limited circumstances described below, the Trust shall be
terminated with the result that the Subordinated Debentures will be distributed
to the holders of the Trust Securities, on a pro rata basis, in lieu of any cash
distribution. In the case of the occurrence of a Special Event that is a Tax
Event, the Company will have the right in certain circumstances to redeem the
Subordinated Debentures, which would result in the redemption by the Trust of
the Trust Securities in the same amount on a pro rata basis. If the Subordinated
Debentures are distributed to the holders of the Preferred Securities, the
Company will use its best efforts to have the Subordinated Debentures listed on
the New York Stock Exchange or on such other exchange as the Preferred
Securities are then listed. See "Description of the Preferred
Securities--Special Event Redemption or Distribution" and "Description of the
Subordinated Debentures."
 
    In the event of the voluntary or involuntary dissolution, winding-up or
termination of the Trust, the holders of the Preferred Securities will be
entitled to receive, for each Preferred Security, a liquidation amount of $25
plus accrued and unpaid distributions thereon (including interest, if any,
thereon) to the date of payment, unless in connection with such dissolution,
winding-up or termination the Subordinated Debentures are distributed to the
holders of the Trust Securities. See "Description of the Preferred
Securities--Liquidation Distribution Upon Termination."

    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
DETAILED INFORMATION APPEARING ELSEWHERE IN THIS PROSPECTUS SUPPLEMENT AND IN

                                  THE COMPANY
 
    Circus Circus Enterprises, Inc. (the "Company") is one of the largest
hotel-casino operators (in terms of rooms and casino square footage) in the
United States. Upon completion of Mandalay Bay, the Company's newest
hotel-casino resort, the Company will own and operate eleven hotel-casino
properties with over 22,000 guest rooms and over 800,000 square feet of gaming
space. The Company also owns a 50% interest in three joint venture casino
properties with approximately 4,700 guest rooms and over 200,000 square feet of
gaming space. In March 1999, Mandalay Bay is expected to open as the centerpiece
of the Company's Masterplan Mile (as defined) on the south end of the Las Vegas
Strip. The Masterplan Mile, which is approximately 230 acres with approximately
one mile of frontage on the Las Vegas Strip, represents a completely new concept
in hotel-casino development. The tropical environment of Mandalay Bay is
designed to ultimately be surrounded by multiple resorts, functioning with Luxor
and Excalibur as a cluster of interconnected entertainment destinations that
have no similarly scaled competition in Las Vegas. The complex will include an
array of distinctively themed hotel-casinos, complemented by restaurants, shops
and entertainment venues catering to a broad spectrum of Las Vegas visitors. For
the year ended January 31, 1998, the Company had revenues and EBITDA (as
defined) of $1.35 billion and $376.9 million, respectively.
 
    Set forth below is certain information as of April 30, 1998 concerning the
properties that are wholly owned and operated by the Company.

NEW CASINO RESORT DEVELOPMENT
 
LAS VEGAS
 
    In the Spring of 1997, the Company commenced construction of Mandalay Bay, a
43-story, hotel-casino resort which will have approximately 3,700 rooms and
approximately 135,000 square feet of gaming space. The resort, which is expected
to be completed in the first quarter of 1999, will be situated on approximately
60 acres of land just south of Luxor. Mandalay Bay's attractions are planned to
include an 11-acre tropical lagoon featuring a sand-and-surf beach, a
three-quarter-mile lazy river ride, a 30,000-square-foot spa and other
entertainment attractions. Inside, Mandalay Bay will offer internationally
renowned restaurants, as well as a House of Blues nightclub and restaurant,
including its signature Foundation Room sited on Mandalay Bay's rooftop, and 100
"music-themed" hotel rooms in Mandalay Bay's towers.
 
    Within Mandalay Bay and as part of its 3,700 rooms, a Four Seasons Hotel
with approximately 400 rooms will provide Las Vegas visitors with a luxury
"five-star" hospitality experience. The Four Seasons Hotel, which will be owned
by the Company and managed by Four Seasons Hotels Limited ("Four Seasons"),
represents the first step pursuant to the Company's cooperative effort with Four
Seasons to identify strategic opportunities for development of hotel and casino
properties worldwide. The cost of Mandalay Bay, including the Four Seasons Hotel
but excluding the land, is currently estimated at approximately $850 million.
See "Risk Factors--Construction Risks" and "--Mandalay Bay Construction."
 
    During the course of construction, Mandalay Bay's hotel tower has
experienced settling which has exceeded the level contemplated in the building's
original design and the amount of settling has been greater in some portions of
the structure than others. The Company has retained geotechnical, structural
 
                                      S-5

engineering and foundation consultants who are evaluating the situation and have
recommended remedial measures which are in the initial stages of implementation.
Completion of the recommended remedial measures is not expected to delay the
opening of Mandalay Bay or materially increase the cost of the project. However,
until such remedial measures are completed and evaluated and the ongoing
evaluation of the site is concluded, there can be no assurances that further
corrective measures will not be required or, if additional measures are
required, as to the cost of such measures or their impact, if any, on the
scheduled completion and opening of Mandalay Bay.
 
    Mandalay Bay is the latest phase of the Company's development of over 230
acres of land it owns at the south end of the Las Vegas Strip which runs from
Tropicana Avenue south approximately one mile to Russell Road ("Masterplan
Mile"). As part of its development plan for Masterplan Mile, the Company is
constructing a 125,000-square-foot convention facility and a 12,000-seat arena.
These facilities are expected to be completed and opened concurrently with
Mandalay Bay, and will represent core components of Masterplan Mile which will
be cross-marketed to guests at the Company's existing and future hotel-casinos
within Masterplan Mile. The estimated cost of the convention facility and arena
is approximately $100 million.
 
    The Company also plans to construct a monorail system which will link the
Company's resorts on Masterplan Mile. Furthermore, the Company is planning a
"Sea of Predators" aquarium exhibit which will likewise represent a core
component of Masterplan Mile. Both the monorail and the Sea of Predators exhibit
are anticipated to be completed after the opening of Mandalay Bay. The cost of
these additional Masterplan Mile core components is estimated at approximately
$75 million. The Company may add other core components to its development plan
for Masterplan Mile in the future.
 
DETROIT, MICHIGAN
 
    The Company has formed a joint venture with the Detroit-based Atwater Casino
Group to build, own and operate a hotel-casino in Detroit, Michigan. The Company
will own a 45% equity interest in the proposed project and receive a management
fee. On November 21, 1997, the joint venture was selected to be one of three
groups permitted to negotiate a development agreement with the City, and its
development agreement was approved by the City Council on April 9, 1998. The
joint venture's ability to proceed with the proposed project is contingent upon
the receipt of all necessary gaming approvals and satisfaction of other
conditions. The joint venture is planning a $600 million project, of which the
Company would be required to contribute 20% of such amount in the form of
equity, with the balance expected to be provided through project-specific
financing. If the Company proceeds with the project, it will guarantee
completion of the project and will be required to give a keep-well guarantee,
pursuant to which the Company would contribute additional funds, if and as
needed, to continue operations of the project for a period of two years. If
permitted by city and state authorities, the Company would consider construction
of a temporary facility. See "Risk Factors--Mississippi and Michigan Voter
Initiatives to Ban Gaming."
 
MISSISSIPPI GULF COAST
 
    The Company has announced that it plans to develop a hotel-casino resort on
the Mississippi Gulf Coast at the north end of the Bay of St. Louis, near the
DeLisle exit on Interstate 10. It is currently anticipated that the resort will
include approximately 1,500 hotel rooms and involve an investment by the Company
of approximately $225 million. The Company has received all necessary approvals
to commence development. However, these approvals have been challenged in state
and federal court, and the Company anticipates that the design and construction
of this project will begin only after satisfactory resolution of all legal
actions. As presently contemplated, the Company will own 90% of the resort, with
a partner contributing the land in exchange for the remaining 10% interest. See
"Risk Factors--Mississippi and Michigan Voter Initiatives to Ban Gaming."
 
                                      S-6

ATLANTIC CITY
 
    The Company has entered into an agreement with Mirage Resorts, Incorporated
("Mirage") to participate in the development of a site located in the Marina
District of Atlantic City, New Jersey. As reported by Mirage, the site consists
of 181 acres, of which approximately 125 acres are developable. The site is the
subject of an agreement between Mirage and Atlantic City which provides (as
reported by Mirage) that the City convey the site to Mirage in exchange for
Mirage's agreeing to develop a hotel/casino thereon and to undertake certain
other obligations.
 
    On January 8, 1998, the City of Atlantic City transferred title to the land
to a subsidiary of Mirage. Shortly thereafter, Mirage purported to cancel its
agreement with the Company, and filed suit to have the agreement declared
invalid. The Company has filed its own suit against Mirage seeking, among other
things, to enforce the agreement. While the Company and Mirage have had
discussions regarding this dispute, there can be no assurances as to when or
whether a settlement can be reached and, in the absence of a settlement, no
assurances can be given as to the outcome of the litigation. In any event,
various governmental permits required for the development of the site have not
yet been received.
 
    Additionally, as reported by Mirage, an existing Atlantic City hotel-casino
operator and others have filed various lawsuits which seek to prevent Mirage's
acquisition of the site and construction of road improvements to the site. These
lawsuits have the potential to delay or prevent the Company's acquisition of a
portion of the site from Mirage and development of a hotel-casino. Moreover, in
order to proceed, the Company must obtain the requisite gaming and other
approvals (including various governmental permits required for the development
of the site) and licenses in New Jersey and various other jurisdictions. While
the Company and a wholly owned subsidiary have initiated the gaming application
process in New Jersey, based upon the contingencies and impediments to this
project, there can be no assurances as to whether or when the Company will
proceed with the development of a hotel-casino on the site or the magnitude of
the Company's investments in any such project.
 
BUSINESS STRATEGY
 
    The Company's objective is to be a leader in resort entertainment, with
casino gaming as its core strength. To achieve this objective, the Company
pursues the following strategies.
 
A LEADER IN EACH OF ITS MARKETS
 
    The Company seeks to be a leading owner and operator of resort destination
properties in major gaming markets within the U.S. by leveraging its
considerable operating expertise, brand value and reputation in the gaming
industry. The Company is pursuing expansion opportunities in major U.S. gaming
markets including Las Vegas, Detroit, Mississippi and Atlantic City. The Company
believes that the expansion projects it is currently pursuing represent
significant growth opportunities that can provide geographic diversity which
would reduce the Company's reliance on any particular U.S. gaming market. The
Company expects that future developments will continue to focus on high growth
gaming markets such as those in which it is currently pursuing expansion
opportunities.
 
DEVELOPMENT OF MASTERPLAN MILE
 
    With its Masterplan Mile, the Company currently controls the largest
development parcel in Las Vegas, encompassing over 230 acres of land and
approximately one mile of frontage on the Las Vegas Strip. Within this property,
Mandalay Bay will be the centerpiece of the Company's "Strip within a Strip"
concept. Mandalay Bay will feature a tropical environment and will be
interconnected to retail shops, world-class restaurants, convention facilities
and a 12,000-seat arena as well as two of the Company's existing casino resorts,
Luxor and Excalibur. Together, these three hotel-casino resorts will represent
over 12,000 rooms and over 350,000 feet of casino space. The long-term plan for
completion of Masterplan Mile
 
                                      S-7

presently includes two additional resorts and additional entertainment
facilities. Management believes Masterplan Mile will represent a unique gaming
resort complex that will have no comparably scaled competition in Las Vegas.
 
OWN AND OPERATE "MUST SEE" DESTINATIONS
 
    Within each of its existing and target markets, the Company seeks to own and
operate one or more gaming resorts that are viewed by visitors as "must see"
properties. To implement this strategy, the Company seeks to develop properties
that are distinctively themed and provide customers with a vacation experience
that includes resort hotel and gaming facilities, premier entertainment events
and high quality dining. Management believes that its existing properties
include gaming resorts that are among the leaders in their respective markets
and further believes that each of its currently planned properties will, once
opened, become one of the destinations of choice in its respective market.
 
TARGET LARGEST SEGMENTS OF VISITORS
 
    The Company targets a broad range of clientele utilizing its strategy of
providing a quality resort experience at an attractive price. With the addition
of Mandalay Bay, the Company is both increasing its commitment to upscale
clientele and expanding its target market to include premium clientele. Inherent
in the design of the Masterplan Mile, the interconnected complex will attract
and service the multisegmented range of the Company's target market in the
world's largest resort venue for gaming entertainment.
 
MAXIMIZE CUSTOMER SATISFACTION THROUGH STRATEGIC ALLIANCES
 
    The Company seeks to create unique destinations within its resorts by
entering into strategic alliances with premier partners. As part of this
strategy, the Company has entered into an agreement with Four Seasons which will
manage a 400-room Four Seasons hotel within Mandalay Bay. Management believes
this arrangement will enhance Mandalay Bay's appeal by providing the option of a
"five star" hospitality experience. This arrangement represents the first step
as part of a planned cooperative effort between these two companies to identify
strategic opportunities for development of hotel and casino properties
worldwide. The Company has also entered into an agreement with the House of
Blues whereby the House of Blues will operate a nightclub and restaurant,
including its signature Foundation Room, within Mandalay Bay which will also
include 100 "music-themed" rooms. The Company believes that this alliance will
offer high-quality, distinctively-themed entertainment which will be an integral
part of the total experience offered both at Mandalay Bay and within Masterplan
Mile.

payment dates for the Preferred Securities will correspond to the interest rate
and interest and other payment dates on the Subordinated Debentures, which will
be the sole assets of the Trust. As a result, if principal or interest is not
paid on the Subordinated Debentures, no amounts will be paid on the Preferred
Securities. See "Description of the Preferred Securities."

make distributions on the Preferred Securities, in which event the Preferred
Securities Guarantee will not apply to such redemptions or distributions until

the cash interest payments attributable thereto. See "Description of the
Preferred Securities--Voting Rights," "Description of the Subordinated
Debentures--Option to Extend Interest Payment Period" and "Certain Federal
Income Tax Consequences--Interest, Original Issue Discount, Premium and Market
Discount."

                                  RISK FACTORS
 
    PROSPECTIVE PURCHASERS OF PREFERRED SECURITIES SHOULD CAREFULLY REVIEW THE
INFORMATION CONTAINED IN OTHER SECTIONS OF THIS PROSPECTUS SUPPLEMENT AND IN THE
ACCOMPANYING PROSPECTUS AND SHOULD PARTICULARLY CONSIDER THE FOLLOWING MATTERS.
 
SUBSTANTIAL LEVERAGE
 
    The Company is highly leveraged. After giving effect to the sale of the
Preferred Securities offered hereby, the Trust's investment of the proceeds from
the issuance of the Preferred Securities in Subordinated Debentures of the
Company and the Company's use of the proceeds from its issuance of the
Subordinated Debentures, as described under "Use of Proceeds," the Company will
have total PRO FORMA consolidated indebtedness of approximately $     billion.
The Company also is and will become a party to various keep-well agreements with
respect to existing and prospective joint ventures in which it has or will have
an interest, which may require that it effectively meet the debt service
obligations of such joint ventures.
 
    The degree to which the Company is leveraged could have important
consequences to holders of the Preferred Securities, including, but not limited
to, the following: (i) the Company's ability to obtain additional financing in
the future for working capital, capital expenditures, acquisitions, general
corporate purposes or other purposes may be restricted; (ii) a significant
portion of the Company's cash flow from operations must be dedicated to the
payment of principal and interest on its indebtedness, thereby reducing the
funds available to the Company for its new projects and operations; (iii)
certain of the Company's borrowings are and will continue to be at variable
rates of interest, which could result in higher interest expense in the event of
an increase in interest rates; and (iv) such indebtedness contains financial and
restrictive covenants, the failure to comply with which may result in an event
of default which, if not cured or waived, could have a material adverse effect
on the Company.
 
    The degree to which the Company is leveraged could also affect its ability
to compete effectively and could limit its business opportunities. If the
Company's cash flow and capital resources are insufficient to fund its debt
service obligations and/or its joint venture obligations, the Company may be
forced to reduce or delay capital expenditures, sell assets or seek to obtain
additional equity capital or to refinance or restructure its indebtedness. There
can be no assurance that the Company's cash flow and capital resources will be
sufficient to meet its debt and other obligations in the future, or that any
such alternative measures would be successful or would permit the Company to
meet its debt service obligations.
 
RESTRICTIVE COVENANTS
 
    The Company's Amended and Restated Loan Agreement dated as of May 23, 1997
with Bank of America National Trust and Savings Association, as Administrative
Agent, and Canadian Imperial Bank of Commerce, Credit Lyonnais Los Angeles
Branch, Societe Generale, The Long-Term Credit Bank of Japan, Ltd., Los Angeles
Agency, Morgan Guaranty Trust Company of New York, PNC Bank, National
Association, Wells Fargo Bank, N.A. and Westdeutsche Landesbank Girozentrale, as
Managing Agents, as amended by Amendment No. 1 thereto dated as of October 3,
1997 and Amendment No. 2 thereto dated as of May 15, 1998, a $2 billion
revolving credit facility (the "Credit Facility"), contains a number of
covenants that impose certain operating and financial restrictions on the
Company and its subsidiaries, including, without limitation, limitations on
indebtedness, liens, guarantees and restricted payments. In addition, the
Company is required under its Credit Facility to maintain a leverage ratio based
on total debt and senior debt. There can be no assurance that the Company will
be able to comply with such covenants or restrictions, or any other financial
covenants in its debt instruments, in the future. The Company's ability to
comply with such covenants and other restrictions may be affected by events
beyond its control, including prevailing economic, financial and industry
conditions. The breach of any such covenant or restriction could result in a
default under the Credit Facility that would permit the lenders thereunder to
 
                                      S-13

declare all amounts outstanding thereunder to be immediately due and payable,
together with accrued and unpaid interest, and to terminate the Credit Facility.
In such event, there can be no assurances as to the Company's ability to
refinance such indebtedness or as to the terms of any such refinancing.
 
COMPETITION
 
    The hotel and casino industry is highly competitive. The Company's Las Vegas
hotel-casino operations, which are conducted primarily from facilities located
along the Las Vegas Strip, currently compete with approximately 27 other major
hotel-casinos and a number of smaller casinos located on or near the Las Vegas
Strip. Such operations also compete with casinos located in downtown Las Vegas,
approximately 11 of which offer hotel, food and beverage and entertainment
facilities, and several major hotel-casinos located elsewhere in the Las Vegas
area. The Company's Las Vegas properties also compete, to a lesser extent, with
casino and hotel facilities in other parts of Nevada, including Laughlin, Reno
and along I-15 (the principal highway between Las Vegas and southern California)
near the California-Nevada state line.
 
    Casino and hotel capacity continues to increase in the Las Vegas market.
During 1997, the number of hotel rooms increased by 11% while the number of
visitors to Las Vegas increased only 3%. This imbalance of supply and demand put
downward pressure on room and occupancy rates in Las Vegas. Las Vegas hotel and
casino capacity is expected to continue to increase significantly. Mandalay Bay
is just one of four major properties, totaling approximately 12,500 rooms, that
will open within a year's span beginning in the fall of 1998. The impact on the
Company of the completion and opening of additional hotel and casino capacity
currently under construction in Las Vegas, including Mandalay Bay, cannot be
determined at this time. While the Company's Las Vegas operations, on a
consolidated basis, had previously benefited from growth of hotel and casino
capacity in the Las Vegas market when the Company was a significant contributor
to the new capacity, its addition of 1,000 rooms at Circus Circus-Las Vegas and
an additional 1,950 at Luxor in 1997 contributed to a growth in hotel capacity
in the Las Vegas market that outpaced market growth in fiscal 1998. The impact
of new capacity currently under construction (including Mandalay Bay) on the
Company's operations will depend, to a significant extent, on the ability of the
new properties to draw additional visitors to the Las Vegas market.
 
    Circus Circus-Reno competes with approximately 13 major casinos (the
majority of which offer hotel rooms), including Silver Legacy, a 1,711-room
hotel-casino complex which is 50% owned by a wholly owned subsidiary of the
Company. Circus Circus-Reno and Silver Legacy also compete with numerous other
smaller casinos in the greater Reno area and, to a lesser extent, with casino
and hotel facilities in Lake Tahoe and other parts of Nevada.
 
    In Laughlin, the Colorado Belle and the Edgewater, which together accounted
for approximately 24% of the rooms in Laughlin as of April 30, 1998, compete
with eight other Laughlin casinos. They also compete with the hotel-casinos in
Las Vegas and those situated on I-15 (the principal highway between Las Vegas
and southern California) near the California-Nevada state line, as well as a
growing number of Native American casinos in Laughlin's regional market. The
Company believes the significant expansion of hotel and casino capacity in Las
Vegas in recent years and the growth of Native American casinos in Laughlin's
central Arizona and southern California feeder markets have had a negative
impact on Laughlin area properties, including the Colorado Belle and the
Edgewater, by drawing visitors from the Laughlin market. This has, in turn,
resulted in increased competition among Laughlin properties for a reduced number
of visitors thus contributing to generally lower revenues and profit margins at
Laughlin properties, including the Colorado Belle and the Edgewater.
 
    The Company's Jean, Nevada properties, Gold Strike and Nevada Landing, are
located on I-15, the principal highway between Las Vegas and southern
California, approximately 25 miles south of Las Vegas and 12 miles north of the
California-Nevada border, and are dependent for their customers almost entirely
on the large number of people traveling between Las Vegas and southern
California. As such, these
 
                                      S-14

properties compete with the large concentration of hotel, casino and other
entertainment options available in Las Vegas as well as three hotel-casinos
clustered at the California-Nevada border.
 
    Gold Strike-Tunica competes with eight other casinos in Tunica County,
Mississippi including Grand Casinos' hotel-casino which opened in 1996 at Buck
Lake, directly north of Gold Strike-Tunica and situated closer to Memphis than
any of the other facilities currently in operation in Tunica County.
 
    The Grand Victoria, a riverboat casino and land-based entertainment complex
owned and operated by a joint venture entity in which the Company owns a 50%
interest, is situated in Elgin, Illinois, a suburb approximately 40 miles
northwest of downtown Chicago. The Grand Victoria, which holds one of ten
riverboat gaming licenses currently granted in Illinois, is located
approximately 20 miles and 40 miles, respectively, from its nearest competitors
in Aurora, Illinois and Joliet, Illinois.
 
    Gaming has expanded dramatically in the United States in recent years. This
growth has been reflected in various forms including riverboats, dockside gaming
facilities, Native American gaming ventures, land-based casinos, state-sponsored
lotteries, off-track wagering and card parlors. Since 1990, when there were
casinos in only three states (excluding casinos on Native American lands),
gaming has spread to a number of additional states and still other states are
currently considering, or may in the future consider, the legalization of casino
gaming in specific geographic areas within their jurisdictions. Casino gaming is
currently conducted by numerous Native American tribes throughout the United
States and other Native American tribes are either in the process of
establishing or are considering the establishment of gaming at additional
locations, including sites in California and Arizona. The November 1998 ballot
in California will include a voter initiative which, if approved by the voters
of California, would mandate that the Governor sign compacts relating to gaming
on tribal lands with California tribes upon their request. The initiative, the
passage of which requires an affirmative vote representing a majority of the
votes cast with respect thereto, would also amend current California law to
permit gambling devices, including slot machines, banked card games and
lotteries at tribal casinos. The competitive impact on Nevada gaming
establishments, in general, and the Company's operations, in particular, from
the continued growth of gaming in jurisdictions outside of Nevada cannot be
determined at this time. The Company believes that the expansion of casino
gaming in areas close to Nevada, such as California and Arizona, could have an
adverse impact on the Company's operations and, depending on the nature,
location and extent of such operations, such impact could be material.
 
RANKING OF OBLIGATIONS UNDER PREFERRED SECURITIES GUARANTEE AND SUBORDINATED
  DEBENTURES
 
    The Company's obligations under the Preferred Securities Guarantee are
subordinate and junior in right of payment to all other liabilities of the
Company and will rank PARI PASSU with the most senior preferred stock issued by
the Company from time to time and with any guarantee that may be entered into by
the Company with respect to any preferred stock of any subsidiary or affiliate
of the Company. The obligations of the Company under the Subordinated Debentures
are subordinate and junior in right of payment to all present and future Senior
Indebtedness (as defined herein) of the Company. No payment of principal of
(including redemption payments), or interest on, the Subordinated Debentures may
be made in the event of certain defaults in respect of Senior Indebtedness. At
April 30, 1998, Senior Indebtedness of the Company aggregated approximately $1.6
billion. In addition, because the Company is a holding company, its obligations
under the Preferred Securities Guarantee and the Subordinated Debentures will be
effectively subordinated to all existing and future liabilities of its
subsidiaries. At April 30, 1998, the subsidiaries of the Company had total
indebtedness and other liabilities of approximately $187 million (excluding, in
each case, indebtedness and other liabilities owed to the Company and other
affiliates, guaranteed indebtedness of subsidiaries that is included in Senior
Indebtedness, deferred income taxes and other deferred credits). There are no
terms in the Preferred Securities, the Subordinated Debentures or the Preferred
Securities Guarantee that limit the Company's ability to incur additional
indebtedness, including indebtedness that ranks senior to the Subordinated
Debentures or the Preferred Securities Guarantee, and there are no limitations
on the ability of its subsidiaries to issue additional indebtedness.
 
                                      S-15

See "Description of the Preferred Securities Guarantee" and "Description of the
Subordinated Debentures--Subordination."
 
RIGHTS UNDER THE PREFERRED SECURITIES GUARANTEE
 
    The Preferred Securities Guarantee guarantees to the holders of the
Preferred Securities the payment of (i) any accrued and unpaid distributions
which are required to be paid on the Preferred Securities, to the extent the
Trust shall have funds available therefor, (ii) the Redemption Price, which
includes all accrued and unpaid distributions to the date of the redemption, to
the extent the Trust has funds available therefor, with respect to any Preferred
Securities called for redemption by the Trust, and (iii) upon a voluntary or
involuntary dissolution, winding-up or termination of the Trust (other than in
connection with the distribution of Subordinated Debentures to the holders of
Preferred Securities), the lesser of (a) the aggregate of the liquidation amount
and all accrued and unpaid distributions on the Preferred Securities to the date
of payment thereof, to the extent the Trust has funds available therefor, and
(b) the amount of assets of the Trust remaining available for distribution to
holders of Preferred Securities in liquidation of the Trust. Holders of the
Preferred Securities have the right to proceed directly against the Company to
enforce the Company's obligations to make payments under the Preferred
Securities Guarantee, without first instituting a legal proceeding against the
Trust, the Preferred Guarantee Trustee (as defined herein) or any other person
or entity. If the Company were to default in its obligation to pay amounts
payable on the Subordinated Debentures, the Trust would lack available funds for
the payment of distributions or amounts payable on redemption of the Preferred
Securities or otherwise, and in such event holders of the Preferred Securities
would not be able to rely upon the Preferred Securities Guarantee for payment of
such amounts. Instead, holders of the Preferred Securities (i) would be able to
proceed directly against the Company to the extent described under "Enforcement
of Certain Rights by Holders of Preferred Securities" below or (ii) would rely
on the enforcement by the Property Trustee (as defined herein) of its rights as
registered holder of the Subordinated Debentures against the Company, pursuant
to the terms of the Subordinated Debentures. See "Description of the Preferred
Securities Guarantee--Status of the Preferred Securities Guarantee" and
"Description of the Subordinated Debentures--Subordination." The Declaration (as
defined herein) provides that each holder of Preferred Securities by acceptance
thereof agrees to the provisions of the Preferred Securities Guarantee and the
Debentures Indenture (as defined herein).
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
 
    If a Declaration Event of Default (as defined herein) occurs and is
continuing, then the holders of Preferred Securities would rely on the
enforcement by the Property Trustee of its rights as the holder of the
Subordinated Debentures against the Company. In addition, the holders of a
majority in aggregate liquidation amount of the Preferred Securities will have
the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Property Trustee or to direct the exercise of any
trust or power conferred upon the Property Trustee under the Declaration,
including the right to direct the Property Trustee to exercise the remedies
available to it as a holder of the Subordinated Debentures. If a Declaration
Event of Default occurs that results from the failure of the Company to pay
principal of or interest on the Subordinated Debentures when due, during the
continuance of such an event of default a holder of Preferred Securities may
institute a legal proceeding directly against the Company to obtain payment of
such principal or interest on Subordinated Debentures having a principal amount
equal to the aggregate liquidation amount of the Preferred Securities owned of
record by such holder. The holders of Preferred Securities will not be able to
exercise directly against the Company any other remedy available to the Property
Trustee unless the Property Trustee first fails to do so. See "Description of
the Preferred Securities--Voting Rights."
 
                                      S-16

OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
    The Company has the right under the Debentures Indenture to defer payments
of interest on the Subordinated Debentures by extending the interest payment
period at any time, and from time to time, on the Subordinated Debentures. As a
consequence of such an extension, quarterly distributions on the Preferred
Securities would be deferred (but despite such deferral would continue to accrue
with interest thereon compounded quarterly) by the Trust during any such
extended interest payment period. Such right to extend the interest payment
period for the Subordinated Debentures is limited to a period not exceeding 20
consecutive quarters for any such extension. In the event that the Company
exercises this right to defer payments of interest, then during the term of such
deferral (a) the Company shall not declare or pay any dividend on, make any
distributions with respect to, or redeem, purchase or make a liquidation payment
with respect to, any of its capital stock, (b) the Company shall not make any
payment of interest, principal or premium, if any, on or repay, repurchase or
redeem any debt securities issued by the Company which rank PARI PASSU with or
junior to the Subordinated Debentures, and (c) the Company shall not make any
guarantee payments (other than pursuant to the Preferred Securities Guarantee)
with respect to the foregoing; PROVIDED, HOWEVER, that the foregoing
restrictions do not apply to any dividend, redemption, interest, principal or
guarantee payments by the Company where the payment is made by way of securities
(including capital stock) that rank junior to the securities on which such
dividend, redemption, interest, principal or guarantee payment is being made.
Prior to the termination of any such Extension Period, the Company may further
defer payments of interest by further extending the interest payment period;
PROVIDED, HOWEVER, that such Extension Period, together with all such previous
and further extensions thereof, may not exceed 20 consecutive quarters or extend
beyond the maturity of the Subordinated Debentures. Upon the termination of any
Extension Period and the payment of all amounts then due, the Company may select
a new Extension Period, as if no Extension Period had previously been declared,
subject to the above requirements. See "Description of the Preferred
Securities--Distributions" and "--Voting Rights" and "Description of the
Subordinated Debentures--Option to Extend Interest Payment Period."
 
    The Company takes the position that the Subordinated Debentures will be
issued with OID at the time of their original issuance and that each U.S. holder
of Preferred Securities will be required to include in gross income such
holder's allocable share of the interest paid on the Subordinated Debentures as
OID. As a result, holders of Preferred Securities will recognize income for
United States federal income tax purposes in advance of the receipt of cash and
will not receive cash from the Trust related to such income if such holder
disposes of such holder's Preferred Securities prior to the record date for the
date on which distributions of such amounts are made. The Company has no current
intention of exercising its right to defer payments of interest by extending the
interest payment period on the Subordinated Debentures. However, should the
Company determine to exercise such right in the future, the market price of the
Preferred Securities is likely to be affected. A holder that disposes of its
Preferred Securities during an Extension Period, therefore, might not receive
the same return on its investment as a holder that continues to hold its
Preferred Securities. In addition, as a result of the existence of the Company's
right to defer interest payments, the market price of the Preferred Securities
(which represent a preferred undivided beneficial interest in the Subordinated
Debentures) may be more volatile than other securities on which original issue
discount accrues that are not subject to such right. See "Certain Federal Income
Tax Consequences--Interest, Original Issue Discount, Premium and Market
Discount."
 
SPECIAL EVENT DISTRIBUTION
 
    Upon the occurrence of a Special Event, the Trust will be terminated, except
in the limited circumstances described below, with the result that the
Subordinated Debentures would be distributed to the holders of the Trust
Securities in connection with the liquidation of the Trust. In the case of a
Special Event that is a Tax Event, the Company shall have the right to redeem
the Subordinated Debentures, in whole but not in part, in which event the Trust
will redeem the Trust Securities. See "Description of the
 
                                      S-17

Preferred Securities--Special Event Redemption or Distribution" and "Certain
Federal Income Tax Consequences."
 
    Under current United States federal income tax law, a distribution of the
Subordinated Debentures upon the termination of the Trust would not be a taxable
event to holders of the Preferred Securities. Upon occurrence of a Tax Event,
however, a termination of the Trust in which holders of the Preferred Securities
receive cash would be a taxable event to such holders. See "Certain Federal
Income Tax Consequences--Receipt of Subordinated Debentures or Cash upon
Liquidation of the Trust."
 
    There can be no assurance as to the market prices for the Preferred
Securities, or the Subordinated Debentures that may be distributed in exchange
for Preferred Securities if a termination of the Trust were to occur.
Accordingly, the Preferred Securities that an investor may purchase, or the
Subordinated Debentures that the investor may receive on dissolution and
liquidation of the Trust, may trade at a discount to the price that the investor
paid to purchase the Preferred Securities offered hereby. Because holders of
Preferred Securities may receive Subordinated Debentures upon the occurrence of
a Special Event, prospective purchasers of Preferred Securities are also making
an investment decision with regard to the Subordinated Debentures and should
carefully review all the information regarding the Subordinated Debentures
contained herein. See "Description of the Preferred Securities--Special Event
Redemption or Distribution" and "Description of the Subordinated Debentures."
 
LIMITED VOTING RIGHTS
 
    Holders of Preferred Securities will have limited voting rights, primarily
in connection with directing the activities of the Property Trustee as the
holder of the Subordinated Debentures. Such holders will not be entitled to vote
to appoint, remove or replace, or to increase or decrease the number of, Company
Trustees, which voting rights are vested exclusively in the Company as the
holder of the Common Securities. See "Description of the Preferred
Securities--Voting Rights."
 
TRADING PRICE OF PREFERRED SECURITIES
 
    The Preferred Securities may trade at a price that does not fully reflect
the value of accrued but unpaid interest with respect to the underlying
Subordinated Debentures. A holder who disposes of his Preferred Securities
between record dates for payments of distributions thereon will be required to
include (to the extent not previously included in income) accrued but unpaid
interest on the Subordinated Debentures through the date of disposition in
income as ordinary income, and the amount realized on disposition will exclude
the portion of the sale price treated as interest. To the extent the amount
realized on disposition is less than the holder's adjusted tax basis, a holder
will recognize a capital loss. Subject to certain limited exceptions, capital
losses cannot be applied to offset ordinary income for United States federal
income tax purposes. See "Certain Federal Income Tax Consequences--Interest,
Original Issue Discount, Premium and Market Discount" and "--Sale of Preferred
Securities."
 
CONSTRUCTION RISKS
 
    As with any major construction project, Mandalay Bay involves (and any other
major construction project the Company or any joint venture in which the Company
owns an interest may undertake, including the proposed Detroit joint venture
project, will involve) many risks, including potential shortages of materials
and labor, work stoppages, labor disputes, weather interference, unforeseen
engineering, environmental or geological problems and unanticipated cost
increases, any of which could give rise to delays or cost overruns.
Construction, equipment or staffing requirements or problems or difficulties in
obtaining any of the requisite licenses, permits, allocations or authorizations
from regulatory authorities could increase the cost or delay the construction or
opening of the facilities or otherwise affect the planned design and features.
It is possible that the existing budget and construction plans for Mandalay Bay
(and/or any budget and construction plans developed for any other project,
including the proposed Detroit joint
 
                                      S-18

venture project) may be changed for competitive or other reasons. In addition,
the Detroit joint venture's proposed project will require it to locate and
purchase a satisfactory site. Accordingly, there can be no assurance that
Mandalay Bay will be completed within the time period or budget currently
contemplated, nor can there be any assurance as to the commencement or
completion of other currently contemplated projects, including the one
contemplated by the Detroit joint venture. See "Prospectus Summary--The
Company--New Casino Resort Development" for information concerning remedial
measures being performed at Mandalay Bay in response to settling of the tower
which has occurred.
 
REGULATION AND LICENSING
 
    The ownership and operation of casino gaming facilities are subject to
extensive state and local regulation. In the States of Illinois, Mississippi and
Nevada licensed gaming operations are currently conducted by the Company through
wholly owned subsidiaries and/or by joint ventures in which wholly owned
subsidiaries of the Company are participants. In Michigan a joint venture in
which a wholly owned subsidiary of the Company is a participant plans (subject
to receipt of the requisite approvals and licenses) to conduct licensed gaming
operations in the future. The Company and a wholly owned subsidiary of the
Company have also filed gaming applications in New Jersey in connection with
plans to acquire land in Atlantic City, construct a hotel-casino and conduct
gaming operations subject to the successful resolution of currently pending
litigation, the receipt of applicable regulatory approvals and the satisfaction
of other conditions. Each of these states as well as the applicable local
authorities in such states, require various licenses, findings of suitability,
registrations, permits and approvals (individually, a "Gaming License" and
collectively, "Gaming Licenses") to be held by the Company and its subsidiaries
and joint ventures that are engaged in gaming operations. The Illinois Gaming
Board, the Michigan Gaming Control Board, the Mississippi Gaming Commission, the
Nevada Gaming Commission, the New Jersey Casino Control Commission and any other
governmental authority which now or hereafter has regulatory authority over any
gaming operations conducted or proposed to be conducted by the Company, any of
its subsidiaries or any joint ventures in which the Company or any entity
wholly-owned by the Company is a participant (individually, a "Gaming Authority"
and collectively, the "Gaming Authorities") may, among other things, deny,
limit, condition, suspend or revoke a Gaming License or approval to own the
stock or joint venture interest of any of the licensed operations conducted in
such states by the Company or its subsidiaries or joint ventures for any cause
deemed reasonable by such licensing authority. Substantial fines or forfeiture
of assets for violations of gaming laws or regulations may be levied against the
Company, such subsidiaries and joint ventures and the individuals involved. The
denial, suspension or revocation of any Gaming License of the Company or any of
its subsidiaries or joint ventures or the levy on the Company or any of such
subsidiaries or joint ventures of substantial fines or forfeiture of assets
could have a material adverse effect on the business of the Company.
 
    To date, the Company has obtained all Gaming Licenses necessary for the
operation of its existing gaming activities. However, Gaming Licenses and
related approvals are deemed to be privileges under Illinois, Mississippi and
Nevada as well as Michigan and New Jersey law, and no assurance can be given
that any new Gaming License that may be required in the future will be granted
or that existing Gaming Licenses will not be revoked or suspended.
 
    The Nevada Gaming Commission (the "Nevada Commission") may, in its
discretion, require the holder of any securities issued by the Company to file
applications, be investigated and be found suitable to own such securities if it
has reason to believe that such ownership would be inconsistent with the
declared policies of the State of Nevada. If the Nevada Commission determines
that a person is unsuitable to own such securities, then pursuant to the Nevada
Gaming Control Act and the regulations promulgated thereunder, the Company can
be sanctioned, including the loss of its approvals, if without the prior
approval of the Nevada Commission, it: (i) pays to the unsuitable person any
dividend, interest or any distribution whatsoever; (ii) recognizes any voting
right by such unsuitable person in connection with such
 
                                      S-19

securities; (iii) pays the unsuitable person remuneration in any form; or (iv)
makes any payment to the unsuitable person by way of principal, redemption,
conversion, exchange, liquidation or similar transaction.
 
    The Illinois Gaming Board and the Mississippi Gaming Commission have
jurisdiction over the holders and beneficial owners of securities issued by the
Company similar to that of the Nevada Commission and may also require their
investigation and approval, the Michigan Gaming Control Board will have such
jurisdiction and authority if a joint venture which includes among its
participants a wholly owned subsidiary of the Company is subsequently licensed
to conduct gaming operations in Detroit, Michigan and the New Jersey Casino
Control Commission will have such jurisdiction and authority if the Company and
a subsidiary of the Company are subsequently licensed to conduct gaming
operations in New Jersey. An applicant must pay all costs of investigation
incurred by a Gaming Authority in conducting an investigation relating to such
applicant.
 
    In certain jurisdictions, including Mississippi and Nevada, the Company may
not make a public offering of its securities without prior approval of the
applicable Gaming Authorities if the securities or proceeds therefrom are
intended to be used to construct, acquire or finance gaming facilities in such
jurisdictions, or to retire or extend obligations incurred for such purposes or
for similar transactions. On May 22, 1997, the Nevada Commission granted the
Company prior approval to make public offerings of its securities for a period
of two years, subject to certain conditions (the "Nevada Shelf Approval"). The
Nevada Shelf Approval also applies to any affiliated company wholly owned by the
Company (a "Gaming Affiliate") which is a publicly traded corporation or would
become a publicly traded corporation pursuant to a public offering. The Nevada
Shelf Approval also includes approval for the Company's registered and licensed
subsidiaries to guarantee any security issued by, and to hypothecate their
assets to secure the payment or performance of any obligation issued by, the
Company or a Gaming Affiliate in a public offering under the Nevada Shelf
Approval. However, the Nevada Shelf Approval may be rescinded for good cause
without prior notice upon the issuance of an interlocutory stop order by the
Chairman of the Nevada State Gaming Control Board (the "Nevada Board") and must
be renewed biennially. The Nevada Shelf Approval does not constitute a finding,
recommendation or approval by the Nevada Commission or the Nevada Board as to
the accuracy or adequacy of this Prospectus Supplement or the accompanying
Prospectus or the investment merits of the securities offered. Any
representation to the contrary is unlawful. The Company received a similar
one-year waiver of approval requirements from the Mississippi Gaming Commission
on January 22, 1998 (the "Mississippi Shelf Approval"). The public offering of
the Subordinated Debentures and the Preferred Securities Guarantees will be made
pursuant to the Nevada Shelf Approval and the Mississippi Shelf Approval, each
as currently in effect or as may be renewed in the discretion of the applicable
Gaming Authority. The public offering of the Preferred Securities offered hereby
does not require any additional prior approval.
 
    The foregoing is only a summary of the regulatory requirements applicable to
the Company and the holders of its securities. For additional information
regarding the gaming laws and regulations applicable to the Company's gaming
operations and the holders of its securities, see the discussion under the
caption "Regulation and Licensing" in Item 1 of the Company's Annual Report on
Form 10-K for the fiscal year ended January 31, 1998, incorporated by reference
in the accompanying Prospectus.
 
MISSISSIPPI AND MICHIGAN VOTER INITIATIVES TO BAN GAMING
 
    In Mississippi, where the Company currently owns and operates one
hotel-casino and plans to build another, two requests have been filed with the
Secretary of State to place on the November 1999 state-wide ballot a voter
initiative to ban gaming in the state. In order for an initiative to be placed
on the November 1999 ballot in Mississippi, the sponsor must obtain approval of
the wording of the initiative for the ballot by Mississippi's Secretary of State
and Attorney General and, after the wording is so approved, obtain 98,336
signatures by October 7, 1998. The wording of the first of these initiatives has
been so approved. However, several groups have filed objections in court to such
initiative contesting its wording, and the local circuit court has supported the
challenge and found the wording of the first initiative invalid. If the
 
                                      S-20

legal process for either initiative is not completed in time for the inclusion
of such initiative on the November 1999 ballot, it is possible that the process
could be completed in time for such initiative to be included on the ballot in
November 2000 or at a later date. Passage of either Mississippi initiative would
require an affirmative vote representing both a majority of the votes cast with
respect to such initiative and at least 40% of the voters casting votes on any
matter in the election.
 
    In Michigan, where a joint venture in which the Company will own a 45%
equity interest plans to build, own and operate a Detroit hotel-casino,
opponents of casino gaming are circulating a petition to compel the inclusion on
the November 1998 state-wide ballot of a proposal to repeal the legislation
authorizing casino gaming in Detroit. Passage of the Michigan initiative would
require the affirmative vote of a majority of the votes cast with respect
thereto. Reference is made to the more detailed discussion of this initiative
under "Regulation and Licensing--Michigan" in Item 1 of the Company's Annual
Report on Form 10-K for the year ended January 31, 1998, incorporated by
reference in the Prospectus.
 
    Approval by the requisite number of voters of either of the aforementioned
Mississippi initiatives or the Michigan initiative would repeal the legislation
authorizing gaming in the state where such approval was obtained subject to the
final results of any legal challenges which might be raised regarding the
initiative and its impact on any current casino operations and/or pending
applications for gaming licenses in such state. The Company is unable to
determine at this time whether any such initiative will be submitted to voters.
If any such initiative is submitted to the voters of Mississippi or Michigan for
their consideration no assurance can be given regarding the outcome of the vote
and/or the impact of the vote on Company's current and/or proposed gaming
operations in such state.
 
MANDATORY DISPOSITION PURSUANT TO GAMING LAWS
 
    The Declaration will provide that each holder and beneficial owner of
Preferred Securities, by accepting or otherwise acquiring an interest in the
Preferred Securities, shall be deemed to have agreed that if the Gaming
Authority of any jurisdiction in which the Company or any of its subsidiaries
(or any joint venture in which the Company or a subsidiary of the Company is a
participant) now or hereafter conducts or proposes to conduct gaming requires
that a person who is a holder or beneficial owner of Preferred Securities must
be licensed, qualified or found suitable, or comply with any other requirement
under applicable Gaming Laws, such holder or beneficial owner shall apply for a
license, qualification or a finding of suitability or comply with such other
requirement, as the case may be, within the prescribed time period. If such
holder or beneficial owner fails to apply to be, or fails to become, licensed or
qualified, is found unsuitable or fails to comply with any other requirement, as
the case may be (a "failure of compliance"), then the Company shall have the
right, at its option (i) to require such person to dispose of its Preferred
Securities or beneficial interest therein within 30 days of receipt of notice of
the Company's election or such earlier date as may be requested or prescribed by
the Gaming Authority or (ii) to purchase such Preferred Securities (which
purchase may be less than 30 days following the notice of purchase if so
requested or prescribed by the Gaming Authority) at a purchase price equal to
the lesser of (A) such person's cost, (B) 100% of the liquidation amount
thereof, plus accrued and unpaid cash distributions to the earlier of the
redemption date and the date of any failure of compliance, or (C) such other
amount as may be required by applicable law or by order of any Gaming Authority.
The Company shall notify the Trustee in writing of any such redemption as soon
as practicable. Neither the Company nor the Trust shall be responsible for any
costs or expenses any such holder or beneficial owner may incur in connection
with its application for a license, qualification or a finding of suitability or
its compliance with any other requirement of a Gaming Authority. The Declaration
will also provide that immediately upon the imposition by a Gaming Authority of
a requirement that a holder or beneficial owner dispose of Preferred Securities,
such holder or beneficial owner shall, to the extent required by applicable
Gaming Laws, have no further right (i) to exercise, directly or indirectly,
through any trustee, nominee or any other person or entity, any right conferred
by the Preferred Securities or (ii) to receive any cash distributions, interest,
 
                                      S-21

dividends or any other distributions or payments with respect to the Preferred
Securities or any remuneration in any form with respect to the Preferred
Securities from the Company, the Trust or the trustees under the Declaration,
except the purchase price referred to above. See "Description of the Preferred
Securities--Mandatory Disposition Pursuant to Gaming Laws."
 
    Under certain circumstances, the holders of the Preferred Securities may be
required to accept distribution of Subordinated Debentures in lieu of a cash
distribution. In such event, provisions similar to those relating to the
mandatory disposition of Preferred Securities pursuant to Gaming Laws will be
included in the Debentures Indenture and will be applicable to the holders of
Subordinated Debentures. See "Description of the Subordinated
Debentures--Mandatory Disposition Pursuant to Gaming Laws."
 
    "Gaming Authority," as defined in the Declaration and in the Debentures
Indenture, means the Nevada Gaming Commission, the Nevada Gaming Control Board,
the Mississippi Gaming Commission, the Illinois Gaming Board, the Michigan
Gaming Control Board, the New Jersey Casino Control Commission, the New Jersey
Division of Gaming Enforcement or any similar federal, state or local
commission, agency or other regulatory body which has, or may at any time after
the date of the Declaration or the Debentures Indenture (as the case may be)
have, jurisdiction over the gaming activities of the Company or a subsidiary of
the Company (or any joint venture in which the Company or a subsidiary of the
Company is a participant) or any successor thereto.
 
    "Gaming Laws," as defined in the Declaration and in the Debentures
Indenture, means the gaming laws of a jurisdiction or jurisdictions to which the
Company or a subsidiary of the Company (or any joint venture in which the
Company or a subsidiary of the Company is a participant) is, or may at any time
after the date of the Declaration or the Debentures Indenture (as the case may
be) be, subject.
 
UNCERTAIN EFFECT OF NATIONAL GAMBLING IMPACT STUDY COMMISSION
 
    A National Gambling Impact Study Commission (the "National Commission") has
been established by the United States Congress to conduct a comprehensive legal
and factual study of the social and economic impact of gaming in the United
States. The National Commission is required by the enabling legislation to issue
a report containing its findings and conclusions, together with recommendations
of the National Commission for legislation and administrative actions, within
two years after the date on which it held its first meeting, which occurred on
June 20, 1997. Any recommendations which may be made by the National Commission
could result in the enactment of new laws and/or the adoption of new regulations
which could adversely impact the gaming industry in general and the Company in
particular. The Company is unable at this time to determine what
recommendations, if any, the National Commission will make, or the ultimate
disposition of any recommendations the National Commission may make.
 
                                      S-22

                                   THE TRUST
 
    The Trust is a statutory business trust formed under Delaware law pursuant
to the filing of a certificate of trust with the Delaware Secretary of State on
June 23, 1998. The Trust's business is defined in a Declaration of Trust, dated
as of June 23, 1998, executed by the Company, as sponsor (the "Sponsor"), and
the Company Trustees as of that date. The Declaration of Trust will be amended
and restated in its entirety (as so amended and restated, the "Declaration")
substantially in the form filed as an exhibit to the Registration Statement of
which this Prospectus Supplement and the accompanying Prospectus form a part.
The Declaration has been qualified as an indenture under the Trust Indenture Act
of 1939, as amended (the "Trust Indenture Act"). Upon issuance of the Preferred
Securities, the purchasers thereof will own all of the Preferred Securities. See
"Description of the Preferred Securities--Book-Entry Issuance Only--The
Depository Trust Company." The Company will directly or indirectly acquire all
of the Common Securities in an aggregate liquidation amount equal to at least 3%
of the total capital of the Trust. The Trust exists for the exclusive purposes
of (i) issuing and selling the Trust Securities, representing undivided
beneficial interests in the assets of the Trust, (ii) investing the gross
proceeds of the Trust Securities in the Subordinated Debentures and the
Preferred Securities Guarantee and (iii) engaging in only those other activities
necessary or incidental thereto. The Trust has a term of approximately
years, but may terminate earlier as provided in the Declaration.
 
    The Trust's business and affairs will be conducted by the trustees (the
"Company Trustees") appointed by the Company, as holder of the Common
Securities. The duties and obligations of the Company Trustees shall be governed
by the Declaration, the Trust Indenture Act and the Delaware Business Trust Act,
as amended (the "Trust Act"). Pursuant to the Declaration, the number of Company
Trustees will initially be five. Three of the Company Trustees (the "Regular
Trustees") will be persons who are employees or officers of, or affiliated with,
the Company. A fourth trustee will be a financial institution unaffiliated with
the Company that will serve as property trustee (the "Property Trustee") under
the Declaration and as indenture trustee for purposes of the Trust Indenture
Act. The Bank of New York will act as the Property Trustee until removed or
replaced by the holder of the Common Securities. The Bank of New York will also
act as indenture trustee under the Preferred Securities Guarantee (the
"Preferred Guarantee Trustee"). See "Description of the Preferred Securities
Guarantee." The fifth trustee will be a financial institution or an affiliate
thereof which maintains a principal place of business in the State of Delaware
(the "Delaware Trustee") and meets any other requirements of applicable law. The
Bank of New York (Delaware) will initially act as the Delaware Trustee.
 
    The Property Trustee will hold title to the Subordinated Debentures for the
benefit of the Trust and holders of the Trust Securities and will have the power
to exercise all rights, powers and privileges under the Debentures Indenture (as
defined herein) as the holder of the Subordinated Debentures. In addition, the
Property Trustee will maintain exclusive control of a segregated non-interest
bearing bank account (the "Property Account") to hold all payments made in
respect of the Subordinated Debentures for the benefit of the Trust and holders
of the Trust Securities. The Property Trustee will make payments of
distributions and payments on liquidation, redemption and otherwise to the
holders of the Trust Securities out of funds from the Property Account. The
Preferred Guarantee Trustee will hold the Preferred Securities Guarantee for the
benefit of the holders of the Preferred Securities. The Company, as the holder
of all the Common Securities, will have the right to appoint, remove or replace
any Company Trustee and to increase or decrease the number of Company Trustees,
provided that the number of Company Trustees shall be at least three, a majority
of which shall be Regular Trustees. The Company will pay all fees, expenses,
debts and obligations (other than the Trust Securities) related to the Trust and
the offering of the Trust Securities. The Company has agreed that the Property
Trustee and any person to whom such fees, expenses, debts and obligations are
owed will have the right to enforce the Company's obligations in respect of such
fees, expenses, debts and obligations directly against the Company without first
proceeding against the Trust. See "Description of the Preferred
Securities--Expenses and Taxes."
 
                                      S-23

    The rights of the holders of the Preferred Securities, including economic
rights, rights to information and voting rights, are as set forth in the
Declaration, the Trust Act, and the Trust Indenture Act. See "Description of the
Preferred Securities."
 
    The principal place of business of the Trust shall be c/o Circus Circus
Enterprise, Inc., 2880 Las Vegas Boulevard South, Las Vegas, Nevada 89109;
telephone (702) 734-0410.
 
                              ACCOUNTING TREATMENT
 
    The financial statements of the Trust will be consolidated into the
Company's consolidated financial statements, with the Preferred Securities
treated as minority interest and shown on the Company's consolidated financial
statements as Company-obligated mandatorily redeemable preferred securities of
the Trust. The sole asset of the Trust will be the      % Subordinated
Deferrable Interest Debentures due            ,     in the principal amount of
$     , which will eliminate upon consolidation of the Trust.
 
                                USE OF PROCEEDS
 
    The net proceeds from the sale of the Preferred Securities, estimated to be
approximately $          , will be invested by the Trust in the Subordinated
Debentures of the Company. The Company will use the net proceeds from the sale
of such Subordinated Debentures principally to          .
 
                                      S-24

                                 CAPITALIZATION
 
    The following table sets forth the Company's cash and capitalization at
April 30, 1998 and as adjusted as of that date to give effect to the sale of the
Preferred Securities offered hereby and the concurrent purchase by the Trust
from the Company of $    million principal amount of Subordinated Debentures,
and the Company's application of the estimated net proceeds therefrom. This
table should be read in conjunction with the Company's Quarterly Report on Form
10-Q for the fiscal quarter ended April 30, 1998 which is incorporated by
reference in the accompanying Prospectus.

(1) Gold Strike, Nevada Landing and Railroad Pass were acquired on June 1, 1995.
    The Hacienda was acquired on September 1, 1995 and closed on December 1,
    1996. Gold Strike-Tunica (formerly Circus Circus-Tunica) opened in August
    1994. Luxor opened in October 1993.
 
(2) EBITDA consists of operating income plus depreciation, preopening expense,
    abandonment losses and other nonrecurring items. Corporate expense also
    contains depreciation which has been added back in the calculation. EBITDA
    is a measure commonly used by the financial community but is not prepared in
    accordance with United States generally accepted accounting principles and
    should not be considered as a measurement of net cash flows from operating
    activities.
 
(3) Items include 100% of the Company's joint venture properties.
 
(4) The ratio of earnings to fixed charges has been computed by dividing net
    income before fixed charges and income taxes, adjusted to exclude
    capitalized interest and equity in undistributed earnings of
    less-than-50%-owned ventures. Fixed charges consist of interest, whether
    expensed or capitalized, amortization of debt discount and issuance costs,
    the Company's proportionate share of the interest cost of 50%-owned
    ventures, and the estimated interest component of rental expense.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION AND ANALYSIS OF THE RESULTS OF OPERATIONS AND
FINANCIAL CONDITION OF THE COMPANY SHOULD BE READ IN CONJUNCTION WITH THE
CONSOLIDATED FINANCIAL STATEMENTS AND THE NOTES THERETO INCLUDED IN THE
COMPANY'S ANNUAL REPORT ON FORM 10-K FOR THE FISCAL YEAR ENDED JANUARY 31, 1998
AND THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO INCLUDED
IN THE COMPANY'S QUARTERLY REPORT ON FORM 10-Q FOR THE FISCAL QUARTER ENDED
APRIL 30, 1998 INCORPORATED BY REFERENCE IN THE ACCOMPANYING PROSPECTUS.
 
FIRST QUARTER FISCAL 1999 COMPARED WITH FIRST QUARTER FISCAL 1998
 
RESULTS OF OPERATIONS
 
REVENUES
 
    Revenues for the Company increased $12.9 million, or 4%, versus the prior
year. The increase in revenues was attributable to two properties. First, the
completion of an 1,100-room hotel tower at Gold Strike-Tunica during the quarter
contributed to an increase in revenues at that property of $14.1 million, or
136%. Second, revenues at Luxor increased $12.1 million, or 17%, due to an
increase in the amount of high-budget play in the casino and the opening of a
new 1,200-seat showroom in the third quarter of the prior year.
 
    The increases noted above were partially offset by decreases in revenues at
both Circus Circus-Las Vegas and Excalibur. Circus Circus declined $2.5 million,
or 4%, while Excalibur declined $3.6 million, or 5%. These decreases are due
primarily to the continued soft market conditions in Las Vegas, particularly
during mid-week periods. Also, an increase in the maximum tax rate on casino
revenues in Illinois from 20% to 35% reduced the contribution from Grand
Victoria (50%-owned by the Company) by $3.1 million, or 27%.
 
OPERATING INCOME
 
    For the quarter ended April 30, 1998, income from operations declined $21.6
million, or 26%, from the prior year. The Company's composite operating margin
was 17.1% versus 24.0% in the prior year quarter. A discussion of operating
results by market follows.
 
LAS VEGAS
 
    The Company's Las Vegas properties posted an overall decrease in operating
income of $14.7 million, or 25%. Declines occurred at all of the Company's
wholly owned properties. At Luxor, operating income fell $5.5 million, or 31%,
as results were affected by the additional costs associated with a new national
advertising campaign which began in February, as well as increases in casino
promotional expenses and a lower hold percentage on table games. At Excalibur,
operating income decreased $4.9 million, or 22%, while Circus Circus decreased
$3.8 million, or 38%. Each of the Company's Las Vegas properties has been
negatively affected by overall soft conditions in the market, particularly
during mid-week.
 
RENO
 
    In Reno, the Company's combined operating income declined $1.8 million, or
24%, versus the year ago quarter. This market suffered from adverse weather
conditions in February, making travel in and out of the area difficult. However,
results in Reno benefitted from the Company recording its priority return from
the 50%-owned Silver Legacy. This priority return began in the second quarter of
the prior year and provides the Company with approximately two-thirds of the
operating income of the joint venture. This priority return in expected to
continue through fiscal 2000.

LAUGHLIN
 
    The Company's two properties in Laughlin, the Colorado Belle and the
Edgewater, posted a combined decrease in operating income of $1.6 million, or
19%. This market continues to suffer from difficult competitive challenges,
foremost of which are the unregulated Native American casinos in Laughlin's
prime central Arizona and southern California feeder markets. Competition from
new resorts in Las Vegas and Primm, Nevada (formerly Stateline, Nevada) has also
contributed to the erosion of Laughlin's customer base.
 
RIVERBOAT MARKETS
 
    In Tunica County, Mississippi, operating income at Gold Strike rose to $1.4
million, a 13% increase over the prior year. During the quarter, the Company
completed construction of a 1,100-room hotel tower.
 
    Results at Grand Victoria (a 50% owned riverboat casino in Elgin, Illinois)
reflected a $3.2 million decrease in the Company's share of operating income. An
increase in the maximum tax rate on casino revenues in Illinois from 20% to 35%
reduced the contribution from Grand Victoria.
 
INTEREST EXPENSE
 
    For the three months ended April 30, 1998, interest expense (excluding joint
venture interest expense) increased $2.2 million versus the prior year. The
increase was due principally to higher average borrowings (approximately $1.9
billion in the current quarter against approximately $1.4 billion last year)
related to various construction projects (primarily the ongoing construction of
Mandalay Bay, the completion of a new hotel tower at Gold Strike-Tunica and the
completion of various improvements at Luxor). Capitalized interest was $7.1
million for the quarter ended April 30, 1998 versus $3.6 million in the year-ago
quarter. Long-term debt at April 30, 1998 stood at $1.9 billion compared to $1.4
billion at April 30, 1997.
 
    The Company also recorded interest expense related to joint venture projects
of $3.2 million in the quarter ended April 30, 1998 compared to $4.2 million in
the previous year. This reflects the Company's 50% share of the interest expense
of Silver Legacy and Monte Carlo.
 
INCOME TAX
 
    For the three months ended April 30, 1998, the Company's effective tax rate
was 39.6% compared with 36.9% for the three months ended April 30, 1997. These
rates reflect the corporate statutory rate of 35% plus the effect of various
nondeductible expenses, including the amortization of goodwill associated with
the acquisition of Gold Strike Resorts.
 
FISCAL 1998 COMPARED WITH FISCAL 1997
 
RESULTS OF OPERATIONS
 
    For the year ended January 31, 1998, the Company reported net income of
$89.9 million, or $.95 per share, compared to $100.7 million, or $.99 per share,
in the prior year. Average shares outstanding totaled 94.9 million as against
101.9 million, reflecting the repurchase of 10.1 million shares of the Company's
stock in fiscal 1997.
 
    During fiscal 1998, the Company recognized approximately $8.0 million in
costs associated with the resignation of its chairman and $3.4 million in
preopening expenses related to the opening of a 1,100-room hotel at its
remodeled Gold Strike Casino Resort in Tunica County, Mississippi. Also during
the year, the Company recognized a $6.0 million gain on the sale of a company
airplane. In the prior year, the Company took one-time asset write-offs totaling
$48.3 million, related primarily to construction and remodeling at Luxor and
Circus Circus-Las Vegas. The Company also recognized $5.6 million in preopening
expenses (reflected in Earnings of Unconsolidated Affiliates) related to the
June 21, 1996, opening of Monte Carlo,
 
                                      S-29

a 50%-owned joint venture hotel/casino on the Las Vegas Strip. Excluding the
effect of these nonrecurring items, earnings per share for fiscal 1998 were
$1.01 versus $1.33 in the prior year.
 
    The decline in earnings was due primarily to two factors. The first was
lower operating income at Excalibur, which faced significant new competition
from New York-New York, Monte Carlo and the expanded Luxor. The second factor
was higher interest expense arising from borrowings in the prior year for the
expansion projects at Luxor and Circus Circus-Las Vegas. Also negatively
affecting results for fiscal 1998 was the closure of the Hacienda Hotel and
Casino in December 1996. This property was demolished to make way for the
construction of Mandalay Bay, the Company's destination resort currently under
construction on the Las Vegas Strip. (See Liquidity and Capital Resources for
additional details regarding Mandalay Bay.) Additionally, the Company sold its
interest in Windsor Casino Limited in January 1997.
 
REVENUES
 
    Revenues for fiscal 1998 increased $20.2 million, or 2%, from the prior
year. This increase was attributable primarily to Luxor, whose revenues grew
$78.2 million, or 34%, on the strength of 1,950 new rooms (however, this
comparison is against a prior year when the property's operations were
significantly disrupted by construction). Circus Circus-Las Vegas posted an
increase in revenues of $11.1 million, or 5%, due to 1,000 new rooms which
opened late last year (though this comparison, too, is with a construction-
disrupted year).
 
    The Company also benefitted from a full year's contribution from Monte
Carlo. This property contributed $34.2 million to the Company's revenues in
fiscal 1998 as against $16.6 million in the prior year, when the property was
open only seven months. (The Company's share of the operating income of joint
ventures is recorded as revenue under Earnings of Unconsolidated Affiliates.)
Meanwhile, the Company's 50% interest in Silver Legacy contributed $20.7 million
to the Company's revenues in fiscal 1998 versus $12.0 million in fiscal 1997.
Effective May 1, 1997, the Company began receiving a priority return on its
investment in Silver Legacy representing approximately two-thirds of the joint
venture's operating income. Based on current projections, the Company
anticipates receiving this priority return for a period of approximately two
years.
 
    The above increases were offset by the closure of the Hacienda in December
1996, which had produced $41.6 million in revenues in fiscal 1997, and by lower
results at Excalibur, whose revenues decreased $23.4 million, or 8%, from their
record level of the prior year.
 
    Casino revenues declined $23.8 million, or 4%, during fiscal 1998. While
Luxor's casino revenues grew 22% due to its expansion, this was offset by the
closure of the Hacienda and a 10% decrease in casino revenues at Excalibur.
Meanwhile, hotel revenues rose $36.4 million, or 12%, due to the additional
rooms at Luxor and Circus Circus-Las Vegas versus the prior year. The Company's
combined hotel occupancy fell from 94% to 88%, compared with a decline in the
overall occupancy in the Las Vegas market from 90% to 86%. Revenues in the
Company's other principal revenue centers (food, beverage, amusements and
retail) were essentially flat against the prior year.
 
INCOME FROM OPERATIONS (EXCLUDING NONRECURRING ITEMS)
 
    Income from operations for fiscal 1998 decreased $28.9 million, or 10%, from
the prior year. The Company's composite operating margin was 18.2%, compared
with 20.6% in fiscal 1997. The principal factor behind this decline was
depreciation expense, which was $26.0 million higher in fiscal 1998 due to the
expansion projects at Luxor and Circus Circus-Las Vegas that were completed in
the prior year. Operating income was also negatively affected by lower results
at Excalibur, closure of the Hacienda and sale of the Company's interest in
Windsor Casino Limited, which in fiscal 1997 had contributed $9.5 million of
operating income to the Company's results. A discussion of operating results by
market follows.
 
                                      S-30

LAS VEGAS
 
    Overall, results at our Las Vegas properties fell below those for the prior
year. In particular, Excalibur's operating income declined $23.6 million, or
26%, from its record level in fiscal 1997. The decline was due to increased
competition and overall weakness in the Las Vegas market. Despite an approximate
11% increase in Las Vegas hotel rooms, the number of visitors to the city grew
by only 3%. The closure of the Hacienda in late 1996 also adversely affected our
results, given that this property had produced $6.4 million in operating income
in fiscal 1997.
 
    At Luxor, operating income increased $12.3 million, or 33%, mainly because
of the 1,950 new rooms placed in service late last year. This property underwent
significant remodeling in fiscal 1997, and certain elements of the remodeling
extended into fiscal 1998. Work continued on the showroom until its opening in
September 1997, and on RA, THE NIGHTCLUB, until its opening in December 1997.
The Company believes this remodeling had a disruptive effect on operations in
fiscal 1998, though not to the same extent as in the prior year.
 
    Operating income at Circus Circus-Las Vegas was slightly below that for the
prior year despite the addition of 1,000 new rooms. While these new rooms ran at
nearly 100% occupancy, additional depreciation expense on the rooms offset much
of the benefit. Moreover, the Company believes that many of the guests staying
at Circus Circus-Las Vegas are spending a portion of their time visiting the
newer megaresorts on the south end of the Las Vegas Strip, and that a number of
the guests staying in the new hotel rooms represent former "walk-in" customers
who were already established as gaming customers.
 
    Monte Carlo--a joint venture with Mirage Resorts--contributed $17.6 million
more in operating income (as the Company's 50% share) than in fiscal 1997, when
the property was open for seven months.
 
RENO
 
    In Reno, operating income at the 50%-owned Silver Legacy rose 34% over the
prior year. The presence of the Women's National Bowling Tournament contributed
to the improved results. Furthermore, effective May 1, 1997, Circus began
receiving a priority return on its investment representing approximately
two-thirds of Silver Legacy's operating income. As a result, Circus' share of
Silver Legacy's operating income rose by $8.7 million from the prior year. At
Circus Circus-Reno, however, operating income was down approximately $1.0
million, or 9%. The casino at that property underwent significant remodeling for
a portion of the summer, which contributed to this decrease.
 
LAUGHLIN
 
    The Company's two properties in Laughlin (Colorado Belle and Edgewater)
produced operating income of $18.1 million as against $25.4 million in the
previous year, a decrease of 29%. The Laughlin market continues to suffer the
brunt of several competitive challenges, most notably the growth of unregulated
Native American casinos. There currently are 37 such casinos in Laughlin's
central Arizona and southern California feeder markets. Competition from Las
Vegas, in the form of major new themed resorts has also eroded Laughlin's
customer base, as have expanded facilities at Primm, Nevada.
 
OTHER MARKETS
 
    In Tunica County, Mississippi, operating income at the recently rechristened
Gold Strike Casino Resort declined by $5.6 million, or 67%, during fiscal 1998.
The property experienced significant disruption due to a $140 million expansion
project which added a 1,100-room hotel and included remodeling and retheming of
the casino. The hotel tower and remodeling were completed in early 1998.
 
    Results at Grand Victoria--a cruising gaming vessel in Elgin, Illinois, in
which the Company has a 50% interest--were below those for the previous year.
The decrease reflected the impact of a full year of additional mandatory
contributions to public entities in the city and county that began in June 1996.
 
                                      S-31

Furthermore, effective January 1998, the Illinois gaming tax was increased.
Based upon last year's gaming revenue, this tax increase is anticipated to
reduce the Company's share of operating income by $9-$10 million in the coming
year.
 
    Results for fiscal 1998 at the Company's other smaller properties were below
those for the prior year.
 
DEPRECIATION AND AMORTIZATION EXPENSE
 
    In fiscal 1998, depreciation and amortization expense rose $26.0 million, to
$129.7 million. This increase stemmed primarily from a full year's depreciation
on the expansion and remodeling projects at Luxor and Circus Circus-Las Vegas.
For fiscal 1999, Circus estimates that its depreciation expense will be
approximately $137 million.

INTEREST EXPENSE
 
    In fiscal 1998, interest expense (excluding joint venture interest expense
and before capitalized interest) rose $40.2 million to $110.9 million. This
increase was due primarily to higher average debt outstanding ($1.6 billion
versus $865 million in fiscal 1997) related to the completed expansion projects
at Luxor and Circus Circus-Las Vegas; the prior-year share repurchase; the
recently completed expansion at Gold Strike-Tunica and the ongoing construction
of Mandalay Bay on the Las Vegas Strip. The increase in interest was partially
offset by higher capitalized interest ($22.0 million versus $16.0 million in
fiscal 1997) related primarily to the Gold Strike-Tunica and Mandalay Bay
projects.
 
    The Company also recorded interest expense related to joint venture projects
of approximately $15.6 million in both fiscal 1998 and fiscal 1997. This
represents the Company's 50% share of Silver Legacy's and Monte Carlo's interest
expense.
 
TAXES
 
    The Company's effective tax rates for the years ended January 31, 1998 and
1997 were 39.2% and 38.5%. These reflect the federal statutory rate of 35% plus
the effect of various nondeductible expenses, primarily the amortization of
goodwill associated with the June 1995 Gold Strike acquisition, and compensation
associated with the resignation of the Company's chairman. For fiscal 1999, the
Company estimates that its tax rate will be approximately 39%.
 
                                      S-32

FISCAL 1997 COMPARED WITH FISCAL 1996
 
RESULTS OF OPERATIONS
 
    Excluding one-time asset write-offs and preopening expenses, earnings per
share for fiscal 1997 were $1.33 compared to $1.66 in the previous year. During
fiscal 1997, the Company took one-time asset write-offs totaling $48.3 million
and recognized $5.6 million in preopening expenses related to the opening of
Monte Carlo. In fiscal 1996, the Company took one-time asset write-offs totaling
$45.1 million and recognized $5.2 million of preopening expenses related to the
opening of Silver Legacy.
 
    The asset write-offs in fiscal 1997 were necessitated by construction and
remodeling at Luxor and Circus Circus-Las Vegas, as well as construction and
remodeling at the Company's other properties. Write-offs in fiscal 1996 related
primarily to a discontinued riverboat project in Chalmette, Louisiana.
 
    The decline in results for fiscal 1997 was due primarily to significant
construction disruption at Luxor and Circus Circus-Las Vegas. Luxor added 1,950
new rooms and remodeled extensive portions of the interior. Meanwhile, Circus
Circus-Las Vegas added a new 1,000-room hotel tower.
 
REVENUES
 
    Revenues for fiscal 1997 increased $34.7 million, or 3%, from fiscal 1996.
This increase was due primarily to the inclusion of a full 12 months of
operations for the properties acquired in the Gold Strike acquisition, compared
to eight months of operations in fiscal 1996. The Company acquired the
properties (Gold Strike, Nevada Landing, Railroad Pass and Grand Victoria) on
June 1, 1995. The Company's 50% ownership in Grand Victoria accounted for the
most significant portion of the revenue increase.
 
INCOME FROM OPERATIONS (EXCLUDING NONRECURRING ITEMS)
 
    Income from operations for fiscal 1997 decreased $25.7 million, or 9%, from
the prior year. The decrease in operating income was due principally to
construction disruptions at Luxor and Circus Circus-Las Vegas.
 
    The Company benefitted from a record year at Excalibur and from the June
1996 opening of Monte Carlo (50% owned by Circus), whose results exceeded
expectations. The Company also benefitted from a full year's operations at
Silver Legacy, a 50/50 joint venture, versus only six months of operations in
fiscal 1996 (the property opened on July 28, 1995). However, the above benefits
were offset by lower results at Circus Circus-Reno whose operating income
declined $13.6 million due to competition from the adjacent Silver Legacy, as
well as winter storms and flooding which struck the market in the fourth
quarter. In addition, the Company continued to experience lower results at its
Laughlin properties and at Circus Circus in Tunica County, Mississippi
(subsequently renamed Gold Strike Casino Resort).
 
DEPRECIATION AND AMORTIZATION EXPENSE
 
    For fiscal 1997, depreciation and amortization expense rose $5.3 million to
$103.7 million. This increase came primarily from a full year's amortization of
goodwill and additional depreciation expense related to the Gold Strike
acquisition in June 1995.
 
INTEREST EXPENSE
 
    Interest expense for fiscal 1997 (excluding joint venture interest expense
and before capitalized interest) rose $10.6 million to $70.7 million. This
increase was due primarily to higher average debt outstanding ($865 million
versus $715 million in fiscal 1996) related to various construction projects
(primarily the new rooms and other improvements at Luxor and Circus Circus-Las
Vegas). The Company also repurchased 10.1 million shares of its common stock.
The increase in fiscal 1997 interest expense was
 
                                      S-33

largely offset by higher capitalized interest ($16.0 million as against $8.6
million in fiscal 1996) related to those same construction projects.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company had cash and cash equivalents of $73.7 million at April 30,
1998, representing normal daily operating requirements. The Company's pretax
cash flow from operations, before asset write-offs, was $97.0 million for the
three months ended April 30, 1998 versus $113.9 million in the prior year, a
decrease of 15%. In this context, pretax cash flow from operations is defined as
the Company's income from operations plus noncash operating expenses (primarily
depreciation and amortization). The Company used its cash flow primarily to fund
the construction of Mandalay Bay, the completion of a new hotel tower at Gold
Strike-Tunica and miscellaneous other construction projects.
 
CAPITAL SPENDING
 
    Capital expenditures for the quarter ended April 30, 1998 were $184.4
million, of which $153.3 million related to the construction of Mandalay Bay and
$14.2 million related to the completion of construction and remodeling at Gold
Strike-Tunica.
 
CREDIT FACILITY
 
    In May 1997, the Company amended its unsecured credit facility with its bank
group, increasing the size of the facility from $1.5 billion to $2.0 billion at
more favorable terms and pricing (see Note 2 of Notes to Condensed Consolidated
Financial Statements incorporated by reference in the accompanying Prospectus).
The Company also has a $1.0 billion commercial paper program which is backed by
the credit facility. As of April 30, 1998, Circus had aggregate borrowings of
$1.1 billion outstanding under the credit facility and commercial paper program
and under the Company's most restrictive loan covenants, it could issue
additional debt of approximately $100 million. In order to provide increased
borrowing capacity during the period when construction of Mandalay Bay is being
completed, the credit facility was amended in May 1998 to provide a more liberal
leverage test on total debt during such period and a new leverage test on total
senior debt.
 
JOINT VENTURES
 
    In July 1995, Silver Legacy, a 50/50 joint venture with the Eldorado
Hotel/Casino, opened in downtown Reno, Nevada. As a condition to the joint
venture's $230 million bank credit agreement, Circus is obligated under a
make-well agreement to make additional contributions to the joint venture as may
be necessary to maintain a minimum coverage ratio (as defined).
 
NEW PROJECTS
 
    The Company is constructing a 3,700-room luxury destination resort set on 60
acres just south of Luxor. Mandalay Bay is slated to open in March 1999 and will
be the third property developed within Masterplan Mile. Mandalay Bay's
attractions will include an 11-acre tropical lagoon featuring a sand-and-surf
beach, a three-quarter-mile lazy river ride, a 30,000-square foot spa and other
entertainment attractions. Inside, Mandalay Bay will offer internationally
renowned restaurants, as well as a House of Blues nightclub and restaurant,
including its signature Foundation Room sited on Mandalay Bay's rooftop and 100
"music-themed" hotel rooms in Mandalay Bay's towers. Within Mandalay Bay and as
part of its 3,700 rooms, there will also be a Four Seasons Hotel of
approximately 400 rooms, which will provide Las Vegas visitors with a luxury
"five-star" hospitality experience. This hotel, owned by Circus and managed by
Four Seasons Regent Hotels and Resorts, represents the first step pursuant to
the Company's cooperative effort with Four Seasons to identify strategic
opportunities for development of hotel and casino properties worldwide. The cost
of Mandalay Bay, includng the Four Seasons Hotel but excluding the land, is
currently
 
                                      S-34

estimated at approximately $850 million and as of April 30, 1998, $418.1 million
in costs had been incurred for this project.
 
    As part of its development plan for Masterplan Mile, the Company is
constructing a 125,000-square foot convention facility and a 12,000-seat arena.
These facilities are expected to be completed and opened concurrently with
Mandalay Bay, and will represent core components of Masterplan Mile which will
be cross-marketed to guests at the Company's existing and future hotel-casinos
within Masterplan Mile. The estimated cost of the convention facility and arena,
excluding the land, is approximately $100 million and as of April 30, 1998, $8.4
million in costs had been incurred for these facilities.
 
    The Company also plans to construct a monorail system which will link the
Company's resorts on Masterplan Mile. Furthermore, the Company is planning a
"Sea of Predators" aquarium exhibit which will likewise represent a core
component of Masterplan Mile. Both the monorail and the Sea of Predators exhibit
are anticipated to be completed after the opening of Mandalay Bay. The cost of
these additional Masterplan Mile core components is estimated at approximately
$75 million. The Company may add other core components to its development plan
for Masterplan Mile in the future.
 
    In Tunica County, Mississippi, the Company recently completed construction
of a 1,100-room tower addition to its casino, which was also remodeled and
rechristened Gold Strike Casino Resort. The remodeled casino opened prior to the
1997 Labor Day weekend and all of the new rooms were in service by March 1998.
The total cost of this expansion was approximately $140 million.
 
    Also in Mississippi, the Company has announced that it plans to develop a
hotel/casino resort on the Mississippi Gulf Coast at the north end of the Bay of
St. Louis, near the DeLisle exit on Interstate 10. The planned resort, which
will have approximately 1,500 rooms, is estimated to cost $225 million. The
Company has received all necessary approvals to commence development. However,
these approvals have been challenged in state and federal court, and the Company
expects construction to begin only after satisfactory resolution of all legal
actions. As the project is presently contemplated, Circus will own 90% of the
resort, with a partner contributing land (up to 500 acres) in exchange for the
remaining 10% interest.
 
    The Company has formed a joint venture with the Detroit-based Atwater Casino
Group, comprised of numerous Detroit-area business, education, civic and
community leaders. Circus will own a 45% equity interest in the proposed project
and receive a management fee. On November 21, 1997, the joint venture was
selected to be one of three groups permitted to negotiate a development
agreement with the city, and its development agreement was approved by the city
council on April 9, 1998. The joint venture's ability to proceed with the
proposed project is contingent upon the receipt of all necessary gaming
approvals and satisfaction of other customary conditions. The joint venture is
planning a $600 million project, of which the Company would be required to
contribute 20% in equity, with the balance provided through project-specific
financing. If the Company proceeds with the project, it will guarantee
completion of the facility and will be required to give a keep-well guarantee,
pursuant to which the Company would contribute additional funds, if and as
needed, to continue operations of the project for a period of two years.
 
    The Company has entered into an agreement with Mirage Resorts to participate
in the development of a site located in the Marina District of Atlantic City,
New Jersey. As reported by Mirage, the site consists of 181 acres, of which
about 125 acres are developable. The site is the subject of an agreement between
Mirage and Atlantic City which provides (as reported by Mirage) that the city
will convey the site to Mirage in exchange for Mirage's agreeing to develop a
hotel/casino thereon and to undertake certain other obligations.
 
    On January 8, 1998, the City of Atlantic City transferred title to the land
to a subsidiary of Mirage. Shortly thereafter, Mirage purported to cancel its
agreement with the Company, and filed suit to have the agreement declared
invalid. The Company has filed its own suit against Mirage seeking, among other
things, to enforce the agreement. While the Company and Mirage have engaged in
discussions concerning the dispute, no resolution has been reached. At this
time, there is no assurance that a satisfactory
 
                                      S-35

settlement can be reached. Nor can there be any assurances as to the eventual
outcome of the pending ligitation In any event, various governmental permits
required for the development of the site have not yet been received.
 
    Additionally, as reported by Mirage, an existing Atlantic City hotel/casino
operator and others have filed various lawsuits which seek to prevent Mirage's
acquisition of the site and construction of road improvements to the site. These
lawsuits have the potential to delay or prevent the Company's acquisition of a
portion of the site from Mirage and development of a hotel/casino. Moreover, in
order to proceed, the Company must obtain the requisite gaming and other
approvals (including various governmental permits required for the development
of the site) and licenses in New Jersey and various other jurisdictions. While
the Company and a wholly owned subsidiary have initiated the gaming application
process, based upon the contingencies and impediments to this project, there can
be no assurances as to whether or when the Company will proceed with the
development of a hotel/casino on the Atlantic City site or the magnitude of the
Company's investment in any such project.
 
OTHER MATTERS
 
    The Company believes that, through a combination of its credit facility,
operating cash flows and ability to raise additional funds through debt or
equity markets, it has sufficient capital resources to meet all of its existing
cash obligations and fund its commitments on the projects underway.
 
MARKET RISK AND DERIVATIVE FINANCIAL INSTRUMENTS
 
    The Company is exposed to market risk in the form of fluctuations in
interest rates and their potential impact upon the Company's variable-rate debt.
The Company manages this market risk by utilizing derivative financial
instruments in accordance with established policies and procedures. The Company
evaluates its exposure to market risk by monitoring interest rates in the
marketplace. The Company does not utilize derivative financial instruments for
trading purposes.
 
    With respect to derivative financial instruments, the Company manages its
exposure to counterparty credit risk by entering into agreements with highly
rated institutions that can be expected to fully perform under the terms of such
agreements. Frequently, these institutions are also members of the bank group
providing the Company's credit facility, which management believes further
minimizes the risk of nonperformance.
 
    The Company's derivative financial instruments consist exclusively of
interest rate swap agreements. Interest differentials resulting from interest
rate swap agreements are recorded on an accrual basis as an adjustment to
interest expense. Interest rate swaps related to debt are matched either with
specific fixed-rate debt obligations or with levels of variable-rate borrowings.
 
    The following table provides information about the Company's derivative and
other financial instruments that are sensitive to changes in interest rates,
including interest rate swaps and debt obligations. For debt obligations, the
table presents principal cash flows and related weighted-average interest rates
by expected maturity dates. For interest rate swaps, the table presents notional
amounts and weighted-average interest rates by contractual maturity dates.
Notional amounts are used to calculate the contractual cash flows to be
exchanged under the contract. Weighted average variable rates are based on
implied
 
                                      S-36

forward rates in the yield curve. Implied forward rates should not be considered
a predictor of actual future interest rates.

YEAR 2000 COMPLIANCE
 
    In the past, many computer software programs were written using two digits
rather than four to define the applicable year. As a result, date-sensitive
computer software may recognize a date using "00" as the year 1900 rather than
the year 2000. This is generally referred to as the "Year 2000 Problem". If this
situation occurs, the potential exists for computer system failures or
miscalculations by computer programs, which could disrupt operations. The
Company is conducting a comprehensive review of its computer systems (as well as
those of its unconsolidated affiliates) to assess its exposure to the Year 2000
Problem and is already in the process of modifying or replacing those systems
that are not Year 2000 compliant. Based upon a preliminary assessment,
management believes that the Company's systems are compliant or will be
compliant by mid-1999. However, if modifications are not made or not completed
within an adequate time frame, the Year 2000 Problem could have a material
adverse impact on the operations of the Company. All maintenance and
modification costs are being expensed as incurred, while the cost of new
hardware or software, when material, is being capitalized and amortized over its
expected useful life. The costs associated with Year 2000 compliance have not
been, nor are they anticipated to be material to the Company's financial
position or results of operations.

                    DESCRIPTION OF THE PREFERRED SECURITIES
 
    The Preferred Securities will be issued pursuant to the terms of the
Declaration. The Declaration has been qualified as an indenture under the Trust
Indenture Act. The Property Trustee will act as the indenture trustee for
purposes of compliance with the provisions of the Trust Indenture Act. The terms
of the Preferred Securities will include those stated in the Declaration and
those made part of the Declaration by the Trust Act and the Trust Indenture Act.
The following summary of the principal terms and provisions of the Preferred
Securities does not purport to be complete and is subject to, and qualified in
its entirety by reference to, the Declaration (the form of which is filed as an
exhibit to the Registration Statement of which this Prospectus Supplement and
the accompanying Prospectus are a part), the Trust Act and the Trust Indenture
Act.
 
GENERAL
 
    The Declaration authorizes the Regular Trustees, on behalf of the Trust, to
issue the Preferred Securities, which represent preferred undivided beneficial
interests in the assets of the Trust, and the Common Securities, which represent
common undivided beneficial interests in the assets of the Trust. All of the
Common Securities will be owned directly or indirectly by the Company. The
Common Securities rank PARI PASSU, and payments will be made thereon on a pro
rata basis, with the Preferred Securities, except that upon the occurrence and
during the continuation of an event of default under the Debentures Indenture,
the rights of the holders of the Common Securities to receive payment of
periodic distributions and payments upon liquidation, redemption and otherwise
will be subordinated to the rights to payment of the holders of the Preferred
Securities. The Declaration does not permit the issuance by the Trust of any
securities other than the Trust Securities or the incurrence of any indebtedness
by the Trust. Pursuant to the Declaration, the Property Trustee will own and
hold the Subordinated Debentures for the benefit of the Trust and the holders of
the Trust Securities. The payment of distributions out of money held by the
Trust, and payments upon redemption of the Preferred Securities or liquidation
of the Trust, are guaranteed by the Company as described under "Description of
the Preferred Securities Guarantee."
 
    The Preferred Guarantee Trustee will hold the Preferred Securities Guarantee
for the benefit of the holders of the Preferred Securities. The Preferred
Securities Guarantee does not cover payment of distributions on the Preferred
Securities when the Trust does not have sufficient available funds in the
Property Account to make such distributions.
 
MANDATORY DISPOSITION PURSUANT TO GAMING LAWS
 
    The Declaration will provide that each holder and beneficial owner of
Preferred Securities, by accepting or otherwise acquiring an interest in the
Preferred Securities, shall be deemed to have agreed that if the Gaming
Authority of any jurisdiction in which the Company or any of its subsidiaries
(or any joint venture in which the Company or a subsidiary of the Company is a
participant) now or hereafter conducts or proposes to conduct gaming requires
that a person who is a holder or beneficial owner of Preferred Securities must
be licensed, qualified or found suitable, or comply with any other requirement
under applicable Gaming Laws, such holder or beneficial owner shall apply for a
license, qualification or a finding of suitability or comply with such other
requirement, as the case may be, within the prescribed time period. If such
holder or beneficial owner fails to apply to be, or fails to become, licensed or
qualified, is found unsuitable or fails to comply with any other requirement, as
the case may be (a "failure of compliance"), then the Company shall have the
right, at its option (i) to require such person to dispose of its Preferred
Securities or beneficial interest therein within 30 days of receipt of notice of
the Company's election or such earlier date as may be requested or prescribed by
the Gaming Authority or (ii) to purchase such Preferred Securities (which
purchase may be less than 30 days following the notice of purchase if so
requested or prescribed by the Gaming Authority) at a purchase price equal to
the lesser of (A) such person's cost, (B) 100% of the liquidation amount
thereof, plus accrued and unpaid cash distributions to the earlier of the
purchase date and the date of any failure of compliance, or (C) such other
amount as may
 
                                      S-38

be required by applicable law or by order of any Gaming Authority. The Company
shall notify the trustees under the Declaration in writing of any such purchase
as soon as practicable. Neither the Company nor the Trust shall be responsible
for any costs or expenses any such holder or beneficial owner may incur in
connection with its application for a license, qualification or a finding of
suitability or its compliance with any other requirement of a Gaming Authority.
The Declaration will also provide that immediately upon the imposition by a
Gaming Authority of a requirement that a holder or beneficial owner dispose of
Preferred Securities, such holder or beneficial owner shall, to the extent
required by applicable Gaming Laws, have no further right (i) to exercise,
directly or indirectly, through any trustee, nominee or any other person or
entity, any right conferred by the Preferred Securities or (ii) to receive any
cash distributions, interest, dividends or any other distributions or payments
with respect to the Preferred Securities or any remuneration in any form with
respect to the Preferred Securities from the Company, the Trust or the trustees
under the Declaration, except the purchase price referred to above.
 
DISTRIBUTIONS
 
    Distributions on the Preferred Securities will be fixed at a rate per annum
of      % of the liquidation amount of $25 per Preferred Security (equivalent to
$     per Preferred Security). Distributions in arrears for more than one
quarter will bear interest at the rate of      % per annum compounded quarterly
(to the extent permitted by applicable law). The term "distributions" as used
herein includes any such interest payable unless otherwise stated.
 
    Distributions on the Preferred Securities will be cumulative, will accrue
from            , 1998, and will be payable quarterly in arrears on            ,
           ,            and            of each year to the holders of record on
the applicable record date, commencing             , 1998, when, as and if
available for payment by the Property Trustee, except as otherwise described
below. The amount of distributions payable for any full quarterly period will be
computed on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarter, on the basis of the actual number of days
elapsed in such a 90-day quarter. The initial distribution, payable on
           , 1998, will be based on a period shorter than a full quarter
(           to            , 1998) and will be in the amount of $     per
Preferred Security.
 
    The Company has the right under the Debentures Indenture to defer payments
of interest on the Subordinated Debentures by extending the interest payment
period from time to time on the Subordinated Debentures which, if exercised,
would defer quarterly distributions on the Preferred Securities (though such
distributions would continue to accrue interest since interest would continue to
accrue on the Subordinated Debentures) during any such extended interest payment
period. In the event that the Company exercises this right, then during the term
of such deferral (a) the Company shall not declare or pay any dividend on, make
any distributions with respect to, or redeem, purchase or make a liquidation
payment with respect to, any of its capital stock, (b) the Company shall not
make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities issued by the Company which rank PARI
PASSU with or junior to the Subordinated Debentures, and (c) the Company shall
not make any guarantee payments (other than pursuant to the Preferred Securities
Guarantee) with respect to the foregoing; PROVIDED, HOWEVER, that the foregoing
restrictions do not apply to any dividend, redemption, liquidation, interest,
principal or guarantee payments by the Company where the payment is made by way
of securities (including capital stock) that rank junior to the securities on
which such dividend, redemption, interest, principal or guarantee payment is
being made. Prior to the termination of any such Extension Period, the Company
may further extend the interest payment period; PROVIDED, HOWEVER, that such
Extension Period, together with all such previous and further extensions
thereof, may not exceed 20 consecutive quarters or extend beyond the maturity of
the Subordinated Debentures. Upon the termination of any Extension Period and
the payment of all amounts then due, the Company may select a new Extension
Period as if no Extension Period had previously been declared, subject to the
above requirements. See "--Voting Rights" below and "Description of the
Subordinated Debentures--Interest" and
 
                                      S-39

"--Option to Extend Interest Payment Period." If distributions are deferred, the
deferred distributions and accrued interest thereon shall be paid to holders of
record of the Preferred Securities, if funds are available therefor, as they
appear on the books and records of the Trust on the record date immediately
following the termination of such Extension Period.
 
    Distributions on the Preferred Securities must be paid on the dates payable
to the extent that the Trust has funds available for the payment of such
distributions in the Property Account. The Trust's funds available for
distribution to the holders of the Preferred Securities will be limited to
payments received under the Subordinated Debentures. See "Description of the
Subordinated Debentures." The payment of distributions out of moneys held by the
Trust is guaranteed by the Company as described under "Description of the
Preferred Securities Guarantee."
 
    Distributions on the Preferred Securities will be payable to the holders
thereof as they appear on the books and records of the Trust on the relevant
record dates, which, as long as the Preferred Securities remain in book-entry
only form, will be one Business Day (as defined herein) prior to the relevant
payment dates, which payment dates correspond to the interest payment dates on
the Subordinated Debentures. Such distributions will be paid through the
Property Trustee, who will hold amounts received in respect of the Subordinated
Debentures in the Property Account for the benefit of the Trust and the holders
of the Trust Securities. Subject to any applicable laws and regulations and the
provisions of the Declaration, each such payment will be made as described under
"--Book-Entry Only Issuance--The Depository Trust Company" below. In the event
the Preferred Securities shall not continue to remain in book-entry only form,
the Regular Trustees shall have the right to select relevant record dates which
shall be at least one Business Day, but less than 60 Business Days, prior to the
relevant payment dates. In the event that any date on which distributions are to
be made on the Preferred Securities is not a Business Day, then payment of the
distributions payable on such date will be made on the next succeeding day which
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 succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date. A "Business
Day" shall mean any day other than a Saturday, Sunday or other day on which
banking institutions in New York, New York are authorized or required by law to
close.
 
MANDATORY AND OPTIONAL REDEMPTION
 
    The Subordinated Debentures will mature on            ,     and may be
redeemed, in whole or in part, at any time on or after            ,     , or at
any time in certain circumstances upon the occurrence of a Tax Event, in each
case at a price equal to the sum of (i) 100% of the principal amount of the
Subordinated Debentures to be redeemed and (ii) accrued and unpaid interest
thereon to the date fixed for redemption. Upon the repayment of the Subordinated
Debentures, whether at maturity or upon acceleration, redemption or otherwise,
the proceeds from such repayment or payment shall simultaneously be applied to
redeem Trust Securities on a pro rata basis having an aggregate liquidation
amount equal to the aggregate principal amount of the Subordinated Debentures so
repaid or redeemed at the Redemption Price; PROVIDED, HOWEVER, that except in
the case of payments upon maturity, holders of Trust Securities shall be given
not less than 30 nor more than 60 days notice of such redemption. See
"--Redemption Procedures" and "Description of the Subordinated Debentures." In
the event that fewer than all of the outstanding Preferred Securities are to be
redeemed, the Preferred Securities will be redeemed as described under
"--Book-Entry Only Issuance--The Depository Trust Company" below.
 
SPECIAL EVENT REDEMPTION OR DISTRIBUTION
 
    DISTRIBUTION UPON THE OCCURRENCE OF A SPECIAL EVENT.  If, at any time, a Tax
Event or an Investment Company Event (each, as defined below, a "Special Event")
shall occur and be continuing, the Trust shall, except in the circumstances
described below under "Redemption Upon the Occurrence of a Tax Event," be
dissolved with the result that, after satisfaction of liabilities to creditors,
Subordinated Debentures, with an
 
                                      S-40

aggregate principal amount equal to the aggregate stated liquidation amount of,
with an interest rate identical to the distribution rate of, and accrued and
unpaid interest equal to accrued and unpaid distributions on, the Trust
Securities, would be distributed to the holders of the Trust Securities, in
liquidation of such holders' interests in the Trust on a pro rata basis, within
90 days following the occurrence of such Special Event; PROVIDED, HOWEVER, that
in the case of the occurrence of a Tax Event, as a condition of such
termination, dissolution and distribution, the Regular Trustees shall have
received an opinion from a nationally recognized independent tax counsel
experienced in such matters (a "No Recognition Opinion"), which opinion may rely
on published revenue rulings of the Internal Revenue Service, to the effect that
neither the Trust nor the holders of the Trust Securities will recognize any
gain or loss for United States federal income tax purposes as a result of such
termination and dissolution of the Trust and the distribution of the
Subordinated Debentures; and, PROVIDED, FURTHER, that, if there is available to
the Trust the opportunity to eliminate, within such 90-day period, the Special
Event by taking some ministerial action, such as filing a form or making an
election, or pursuing some other similar reasonable measure, which has no
adverse effect on the Trust, the Company or the holders of the Trust Securities,
the Trust will pursue such measure in lieu of dissolution.
 
    If Subordinated Debentures are distributed to the holders of the Preferred
Securities, the Company will use its best efforts to have the Subordinated
Debentures listed on the New York Stock Exchange or on such other exchanges as
the Preferred Securities are then listed.
 
    After the date for any distribution of Subordinated Debentures upon
termination of the Trust, (i) the Preferred Securities and Preferred Securities
Guarantee will no longer be deemed to be outstanding, (ii) the depositary or its
nominee, as the record holder of the Preferred Securities, will receive a
registered global certificate or certificates representing the Subordinated
Debentures to be delivered upon such distribution and (iii) any certificates
representing Preferred Securities not held by the depositary or its nominee will
be deemed to represent Subordinated Debentures having an aggregate principal
amount equal to the aggregate stated liquidation amount of, with an interest
rate identical to the distribution rate of, and accrued and unpaid interest
equal to accrued and unpaid distributions on, such Preferred Securities, until
such certificates are presented to the Company or its agent for transfer or
reissuance.
 
    There can be no assurance as to the market prices for the Preferred
Securities or the Subordinated Debentures that may be distributed in exchange
for the Preferred Securities if a termination and liquidation of the Trust were
to occur. Accordingly, the Preferred Securities that an investor may purchase,
whether pursuant to the offer hereby or in the secondary market, or the
Subordinated Debentures that the investor may receive on termination and
liquidation of the Trust, may trade at a discount to the price that the investor
paid to purchase the Preferred Securities.
 
    REDEMPTION UPON THE OCCURRENCE OF A TAX EVENT  If, in the case of the
occurrence and continuation of a Tax Event, (i) the Company has received an
opinion (a "Redemption Tax Opinion") from a nationally recognized independent
tax counsel experienced in such matters that, as a result of a Tax Event, there
is more than an insubstantial risk that the Company would be precluded from
deducting the interest on the Subordinated Debentures for United States federal
income tax purposes even after the Subordinated Debentures were distributed to
the holders of Trust Securities in liquidation of such holders' interests in the
Trust as described above under "Distribution Upon the Occurrence of a Special
Event" or (ii) the Regular Trustees shall have been informed by such tax counsel
that a No Recognition Opinion cannot be delivered, the Company shall have the
right, upon not less than 30 nor more than 60 days' notice, to redeem the
Subordinated Debentures in whole or in part for cash within 90 days following
the occurrence of such Tax Event at a price equal to the sum of (x) 100% of the
principal amount of the Subordinated Debentures to be redeemed and (y) accrued
and unpaid interest thereon to the date fixed for redemption, and, following
such redemption, Trust Securities with an aggregate liquidation amount equal to
the aggregate principal amount of the Subordinated Debentures so redeemed shall
be redeemed by the Trust at the Redemption Price on a pro rata basis; PROVIDED,
HOWEVER, that, if there is available to the Company or the Trust the opportunity
to eliminate, within such 90-day period, the Tax Event by taking some
ministerial
 
                                      S-41

action, such as filing a form or making an election, or pursuing some other
similar reasonable measure which has no adverse effect on the Trust, the Company
or the holders of the Trust Securities, the Company or the Trust will pursue
such measure in lieu of redemption.
 
    It has recently been reported that the Internal Revenue Service challenged
the deductibility, for U.S. federal income tax purposes, of interest payments
pursuant to instruments analogous to the Subordinated Debentures, held by an
entity similar in certain respects to the Trust. Based on the information
available to it, the Company does not believe that deductibility of interest
pursuant to the Subordinated Debentures is jeopardized by the position reported
to have been taken by the Internal Revenue Service, and the Company intends to
take the position that the interest payments pursuant to the Subordinated
Debentures will be deductible by the Company for federal income tax purposes.
See "Certain Federal Income Tax Consequences--Classification of the Subordinated
Debentures." Adverse developments in respect of the reported proceeding, or
otherwise, could give rise to a Tax Event.
 
    DEFINITIONS.  As used herein the following terms have the meanings specified
below:
 
    "Investment Company Event" means that the Company has provided the Regular
Trustees with an opinion from a nationally recognized independent counsel
experienced in practice under the 1940 Act (as hereinafter defined) to the
effect that, as a result of the occurrence of a change in law or regulation or a
written change in interpretation or application of law or regulation by any
legislative body, court, governmental agency or regulatory authority (a "Change
in 1940 Act Law"), there is more than an insubstantial risk that the Trust is or
will be considered an "investment company" which is required to be registered
under the Investment Company Act of 1940, as amended (the "1940 Act"), which
Change in 1940 Act Law becomes effective on or after the date of this Prospectus
Supplement.
 
    "Tax Event" means that the Company has provided the Regular Trustees with an
opinion from a nationally recognized independent tax counsel experienced in such
matters (a "Dissolution Tax Opinion") to the effect that, on or after the date
of this Prospectus Supplement, as a result of (a) any amendment to, or change
(including any announced prospective change) in, the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein or (b) any interpretation or application of such
laws or regulations by any court, governmental agency or regulatory authority,
in each case which amendment or change is enacted, promulgated, issued or
announced or which interpretation is issued or announced or which action is
taken, on or after the date of this Prospectus Supplement, there is more than an
insubstantial risk that (i) the Trust is, or will be within 90 days of the date
thereof, subject to United States federal income tax with respect to interest
accrued or received on the Subordinated Debentures, (ii) interest payable to the
Trust on the Subordinated Debentures is not, or will not be within 90 days of
the date thereof, deductible in whole or in part by the Company for United
States federal income tax purposes or (iii) the Trust is, or will be within 90
days of the date thereof, subject to more than a de minimis amount of other
taxes, duties or other governmental charges.
 
REDEMPTION PROCEDURES
 
    The Trust may not redeem fewer than all of the outstanding Preferred
Securities unless all accrued and unpaid distributions have been paid on all
Trust Securities for all quarterly distribution periods terminating on or prior
to the date of redemption.
 
    If the Trust gives a notice of redemption in respect of Preferred Securities
(which notice will be irrevocable), then, by 12:00 noon, New York City time, on
the redemption date, provided that the Company has paid to the Property Trustee
a sufficient amount of cash in connection with the related redemption or
maturity of the Subordinated Debentures, the Trust will irrevocably deposit with
the depositary funds sufficient to pay the applicable Redemption Price and will
give the depositary irrevocable instructions and authority to pay the Redemption
Price to the holders of the Preferred Securities. See "--Book-Entry Only
Issuance--The Depository Trust Company." If notice of redemption shall have been
given and funds deposited as required, then immediately prior to the close of
business on the date of such
 
                                      S-42

deposit, distributions will cease to accrue and all rights of holders of such
Preferred Securities so called for redemption will cease, except the right of
the holders of such Preferred Securities to receive the Redemption Price, but
without interest on such Redemption Price. In the event that any date fixed for
redemption of Preferred Securities is not a Business Day, then payment of the
Redemption Price payable on such date will be made on the next succeeding day
which is a Business Day (and without any interest or other payment in respect of
any such delay), except that, if such Business Day falls in the next calendar
year, such payment will be made on the immediately preceding Business Day. In
the event that payment of the Redemption Price in respect of Preferred
Securities is improperly withheld or refused and not paid either by the Trust or
by the Company pursuant to the Preferred Securities Guarantee, distributions on
such Preferred Securities will continue to accrue, from the original redemption
date to the actual date of payment, in which case the actual payment date will
be considered the date fixed for redemption for purposes of calculating the
Redemption Price.
 
    In the event that fewer than all of the outstanding Preferred Securities are
to be redeemed, the Preferred Securities will be redeemed as described under
"--Book-Entry Only Issuance--The Depository Trust Company" below.
 
    Subject to the foregoing and to applicable law (including, without
limitation, United States federal securities laws), the Company or its
affiliates may, at any time and from time to time, purchase outstanding
Preferred Securities by tender, in the open market or by private agreement.
 
LIQUIDATION DISTRIBUTION UPON TERMINATION
 
    In the event of any voluntary or involuntary termination, dissolution or
winding-up of the Trust, the holders of the Preferred Securities at that time
will be entitled to receive out of the assets of the Trust, after satisfaction
of liabilities to creditors, distributions in an amount equal to the aggregate
liquidation amount of $25 per Preferred Security plus accrued and unpaid
distributions thereon to the date of payment (the "Liquidation Distribution"),
unless in connection with such termination, dissolution or winding-up
Subordinated Debentures in an aggregate principal amount equal to the aggregate
liquidation amount of, with an interest rate identical to the distribution rate
of, and accrued and unpaid interest equal to accrued and unpaid distributions
on, the Preferred Securities have been distributed on a pro rata basis to the
holders of Preferred Securities in exchange for such Preferred Securities.
 
    If, upon any such termination, dissolution or winding-up, the Liquidation
Distribution can be paid only in part because the Trust has insufficient assets
available to pay in full the aggregate Liquidation Distribution, then the
amounts payable directly by the Trust on the Preferred Securities shall be paid
on a pro rata basis. The holders of the Common Securities will be entitled to
receive distributions upon any such dissolution pro rata with the holders of the
Preferred Securities, except that if a Declaration Event of Default has occurred
and is continuing, the Preferred Securities shall have a preference over the
Common Securities with regard to such distributions.
 
    Pursuant to the Declaration, the Trust shall terminate (i) on June 23, 2053,
the expiration of the term of the Trust, (ii) upon the bankruptcy of the Company
or the holder of the Common Securities, (iii) upon the filing of a certificate
of dissolution or its equivalent with respect to the Company or the holder of
the Common Securities, the filing of a certificate of cancellation with respect
to the Trust, or the revocation of the charter of the Company or the holder of
the Common Securities and the expiration of 90 days after the date of revocation
without a reinstatement thereof, (iv) upon the distribution of the Subordinated
Debentures following the occurrence of a Special Event, (v) upon the entry of a
decree of a judicial dissolution of the Company or the holder of the Common
Securities or the Trust or (vi) upon the redemption of all of the Trust
Securities.
 
                                      S-43

DECLARATION EVENTS OF DEFAULT
 
    An event of default under the Debentures Indenture (a "Debentures Indenture
Event of Default") (see "Description of the Subordinated Debentures--Debentures
Indenture Event of Default") constitutes an event of default under the
Declaration with respect to the Trust Securities (a "Declaration Event of
Default"); PROVIDED, HOWEVER, that pursuant to the Declaration, the holder of
the Common Securities will be deemed to have waived any Declaration Event of
Default with respect to the Common Securities or its consequences until all
Declaration Events of Default with respect to the Preferred Securities have been
cured, waived or otherwise eliminated. Until such Declaration Events of Default
with respect to the Preferred Securities have been so cured, waived or otherwise
eliminated, the Property Trustee will be deemed to be acting solely on behalf of
the holders of the Preferred Securities and only the holders of the Preferred
Securities will have the right to direct the Property Trustee with respect to
certain matters under the Declaration, and therefore the Debentures Indenture.
If a Declaration Event of Default with respect to the Preferred Securities is
waived by holders of Preferred Securities, such waiver will also constitute the
waiver of such Declaration Event of Default with respect to the Common
Securities for all purposes under the Declaration, without any further act, vote
or consent of the holders of the Common Securities.
 
    During the existence of a Declaration Event of Default, the Property
Trustee, as the sole holder of the Subordinated Debentures, will have the right
under the Debentures Indenture to declare the principal of, and interest on, the
Subordinated Debentures to be immediately due and payable.
 
    If a Declaration Event of Default occurs that results from the failure of
the Company to pay principal of or interest on the Subordinated Debentures when
due, during the continuance of such an event of default a holder of Preferred
Securities may institute a legal proceeding directly against the Company to
obtain payment of such principal or interest on Subordinated Debentures having a
principal amount equal to the aggregate liquidation amount of the Preferred
Securities owned of record by such holder. The holders of Preferred Securities
will not be able to exercise directly against the Company any other remedy
available to the Property Trustee unless the Property Trustee first fails to do
so. See "--Voting Rights."
 
VOTING RIGHTS
 
    Except as provided below and except as provided under the Trust Act, the
Trust Indenture Act and under "Description of the Preferred Securities
Guarantee--Amendments and Assignment" below, and except as otherwise required by
law and the Declaration, the holders of the Preferred Securities will have no
voting rights. In the event that the Company elects to defer payments of
interest on the Subordinated Debentures as described above under
"--Distributions," the holders of the Preferred Securities do not have the right
to appoint a special representative or trustee or otherwise act to protect their
interests.
 
    Subject to the requirement of the Property Trustee obtaining a tax opinion
as set forth in the last sentence of this paragraph, the holders of a majority
in aggregate liquidation amount of the Preferred Securities have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Property Trustee, or to direct the exercise of any trust or
power conferred upon the Property Trustee under the Declaration, including the
right to direct the Property Trustee, as the holder of the Subordinated
Debentures, to (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Subordinated Debentures Trustee (as
hereinafter defined) under the Debentures Indenture with respect to the
Subordinated Debentures, (ii) waive any past Debentures Indenture Event of
Default which is waivable under the Debentures Indenture, (iii) exercise any
right to rescind or annul a declaration that the principal of all the
Subordinated Debentures shall be due and payable, or (iv) consent to any
amendment, modification or termination of the Debentures Indenture or the
Subordinated Debentures, where such consent shall be required, provided that
where a consent under the Debentures Indenture would require the consent of the
holders of greater than a majority in principal amount of Subordinated
Debentures affected thereby (a "Super-Majority"), only the holders of at least
the proportion in liquidation amount of the Preferred Securities which the
relevant Super-Majority represents
 
                                      S-44

of the aggregate principal amount of the Subordinated Debentures may direct the
Property Trustee to give such consent. If the Property Trustee fails to enforce
its rights under the Declaration (including, without limitation, its rights,
powers and privileges as the holder of the Subordinated Debentures under the
Debentures Indenture), a holder of Preferred Securities may to the extent
permitted by applicable law institute a legal proceeding directly against any
person to enforce the Property Trustee's rights under the Declaration without
first instituting any legal proceeding against the Property Trustee or any other
person or entity. Following and during the continuance of a Declaration Event of
Default that results from the failure of the Company to pay principal of or
interest on the Subordinated Debentures when due, a holder of Preferred
Securities may also proceed directly against the Company, without first waiting
to determine if the Property Trustee has enforced its rights under the
Declaration, to obtain payment of such principal or interest on Subordinated
Debentures having a principal amount equal to the aggregate liquidation amount
of the Preferred Securities owned of record by such holder. The Property Trustee
shall notify all holders of the Preferred Securities of any notice of default
received from the Subordinated Debentures Trustee with respect to the
Subordinated Debentures. Such notice shall state that such Debentures Indenture
Event of Default also constitutes a Declaration Event of Default. The Property
Trustee shall not take any action described in clauses (i), (ii), (iii) or (iv)
above unless the Property Trustee has obtained an opinion of independent tax
counsel to the effect that, as a result of such action, the Trust will not be
classified as other than a grantor trust for United States federal income tax
purposes and each holder of Trust Securities will be treated as owning an
undivided beneficial interest in the Subordinated Debentures.
 
    In the event the consent of the Property Trustee, as the holder of the
Subordinated Debentures, is required under the Debentures Indenture with respect
to any amendment, modification or termination of the Debentures Indenture, the
Property Trustee shall request the direction of the holders of the Trust
Securities with respect to such amendment, modification or termination. The
Property Trustee shall vote with respect to such amendment, modification or
termination as directed by a majority in liquidation amount of the Preferred
Securities and, if no Declaration Event of Default has occurred and is
continuing, a majority in liquidation amount of the Common Securities, voting
together as a single class, provided that where a consent under the Debentures
Indenture would require the consent of a Super-Majority, the Property Trustee
may only give such consent at the direction of the holders of at least the
proportion in liquidation amount of the Preferred Securities and Common
Securities, respectively, which the relevant Super-Majority represents of the
aggregate principal amount of the Subordinated Debentures outstanding. The
Property Trustee shall not take any such action in accordance with the
directions of the holders of the Trust Securities unless the Property Trustee
has obtained an opinion of independent tax counsel to the effect that, as a
result of such action, the Trust will not be classified as other than a grantor
trust for United States federal income tax purposes.
 
    A waiver of a Debentures Indenture Event of Default will constitute a waiver
of the corresponding Declaration Event of Default.
 
    Any required approval or direction of holders of Preferred Securities may be
given at a separate meeting of holders of Preferred Securities convened for such
purpose, at a meeting of all of the holders of Trust Securities or pursuant to
written consent. The Regular Trustees will cause a notice of any meeting at
which holders of Preferred Securities are entitled to vote, or of any matter
upon which action by written consent of such holders is to be taken, to be
mailed to each holder of record of Preferred Securities. Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such holders are entitled to vote or of
such matter upon which written consent is sought and (iii) instructions for the
delivery of proxies or consents. No vote or consent of the holders of Preferred
Securities will be required for the Trust to redeem and cancel Preferred
Securities or distribute Subordinated Debentures in accordance with the
Declaration.
 
    Notwithstanding that holders of Preferred Securities are entitled to vote or
consent under any of the circumstances described above, any of the Preferred
Securities that are owned at such time by the
 
                                      S-45

Company or any entity directly or indirectly controlling or controlled by, or
under direct or indirect common control with, the Company, shall not be entitled
to vote or consent and shall, for purposes of such vote or consent, be treated
as if they were not outstanding.
 
    The procedures by which holders of Preferred Securities may exercise their
voting rights are described below. See "--Book-Entry Only Issuance--The
Depository Trust Company."
 
    Holders of the Preferred Securities will have no rights to appoint or remove
the Company Trustees, who may be appointed, removed or replaced solely by the
Company, as the direct or indirect holder of all the Common Securities.
 
MODIFICATION OF THE DECLARATION
 
    The Declaration may be amended or modified if approved and executed by a
majority of the Regular Trustees (or if there are two or fewer Regular Trustees,
by all of the Regular Trustees), provided that if any proposed amendment
provides for (i) any action that would adversely affect the powers, preferences
or special rights of the Trust Securities, whether by way of amendment to the
Declaration or otherwise or (ii) the dissolution, winding-up or termination of
the Trust other than pursuant to the terms of the Declaration, then the holders
of the Trust Securities as a single class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of a majority in liquidation amount of the Trust
Securities affected thereby, provided that a reduction of the principal amount
or the distribution rate, or a change in the payment dates or maturity of the
Preferred Securities, shall not be permitted without the consent of each holder
of Preferred Securities. In the event any amendment or proposal referred to in
clause (i) above would adversely affect only the Preferred Securities or the
Common Securities, then only the affected class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of a majority in liquidation amount of such class of
Trust Securities. In addition, if any such proposed amendment or modification
affects the rights, powers, duties, obligations or immunities of the Property
Trustee or the Delaware Trustee such amendment or modification shall also
require the written approval of the Property Trustee or the Delaware Trustee, as
the case may be.
 
    Notwithstanding the foregoing, no amendment or modification may be made to
the Declaration if such amendment or modification would (i) cause the Trust to
be classified for purposes of United States federal income taxation as other
than a grantor trust, (ii) reduce or otherwise adversely affect the powers of
the Property Trustee in contravention of the Trust Indenture Act or (iii) cause
the Trust to be deemed to be an "investment company" which is required to be
registered under the 1940 Act.
 
EXPENSES AND TAXES
 
    In the Declaration, the Company has agreed to pay for all debts and other
obligations (other than with respect to the Trust Securities) and all costs and
expenses of the Trust (including costs and expenses relating to the organization
of the Trust, the fees and expenses of the Company Trustees and the costs and
expenses relating to the operation of the Trust) and to pay any and all taxes
and all costs and expenses with respect thereto (other than United States
withholding taxes) to which the Trust might become subject. The foregoing
obligations of the Trust under the Declaration are for the benefit of, and shall
be enforceable by, the Property Trustee and any person to whom any such debts,
obligations, costs, expenses and taxes are owed (a "Creditor") whether or not
such Creditor has received notice thereof. The Property Trustee and any such
Creditor may enforce such obligations of the Trust directly against the Company,
and the Company has irrevocably waived any right or remedy to require that the
Property Trustee or any such Creditor take any action against the Trust or any
other person before proceeding against the Company. The Company has also agreed
in the Declaration to execute such additional agreements as may be necessary or
desirable to give full effect to the foregoing agreement of the Company.
 
                                      S-46

MERGERS, CONSOLIDATIONS OR AMALGAMATIONS
 
    The Trust may not consolidate, amalgamate, merge with or into, 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. The Trust may, with the consent of a majority of the Regular
Trustees and without the consent of the holders of the Trust Securities, the
Delaware Trustee or the Property Trustee, consolidate, amalgamate, merge with or
into, or be replaced by a trust organized as such under the laws of any State;
provided, that (i) such successor entity either (x) expressly assumes all of the
obligations of the Trust with respect to the Trust Securities or (y) substitutes
for the Trust Securities other securities having substantially the same terms as
the Trust Securities (the "Successor Securities") so long as the Successor
Securities rank the same as the Trust Securities rank in priority with respect
to distributions and payments upon termination, liquidation, redemption,
maturity and otherwise, (ii) the Company expressly acknowledges a trustee of
such successor entity which possesses the same powers and duties as the Property
Trustee as the holder of the Subordinated Debentures, (iii) if the Preferred
Securities are at such time listed on any national securities exchange or with
another organization, the Successor Securities will be listed, upon notification
of issuance, on any national securities exchange or other organization on which
the Preferred Securities are then listed, (iv) such merger, consolidation,
amalgamation or replacement does not cause the Preferred Securities (including
any Successor Securities) to be downgraded by any nationally recognized
statistical rating organization, (v) such merger, consolidation, amalgamation or
replacement does not adversely affect the rights, preferences and privileges of
the holders of the Trust Securities (including any Successor Securities) in any
material respect (other than with respect to any dilution of the holders'
interest in the successor entity), (vi) such successor entity has a purpose
identical to that of the Trust, (vii) prior to such merger, consolidation,
amalgamation or replacement, the Company has received an opinion from
independent counsel to the Trust experienced in such matters to the effect that
(A) such merger, consolidation, amalgamation or replacement does not adversely
affect the rights, preferences and privileges of the holders of the Trust
Securities (including any Successor Securities) in any material respect (other
than with respect to any dilution of the holders' interest in the successor
entity), and (B) following such merger, consolidation, amalgamation or
replacement, neither the Trust nor such successor entity will be required to
register as an investment company under the 1940 Act and (viii) the Company
guarantees the obligations of such successor entity under the Successor
Securities at least to the extent provided by the Preferred Securities
Guarantee. Notwithstanding the foregoing, the Trust shall not, except with the
consent of holders of 100% in liquidation amount of the Trust 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 such consolidation, amalgamation, merger or replacement would
cause the Trust or the successor entity to be classified for United States
federal income tax purposes as other than a grantor trust for United States
federal income tax purposes and any holder of Trust Securities not to be treated
as owning an undivided beneficial interest in the Subordinated Debentures.
 
BOOK-ENTRY ONLY ISSUANCE--THE DEPOSITORY TRUST COMPANY
 
    The Depository Trust Company ("DTC") will act as securities depositary for
the Preferred Securities. The Preferred Securities will be issued only as fully
registered securities registered in the name of Cede & Co. (DTC's nominee). One
or more fully registered global Preferred Securities certificates will be
issued, representing in the aggregate the total number of Preferred Securities,
and will be deposited with DTC.
 
    The laws of some jurisdictions require that certain purchasers of securities
take physical delivery of securities in definitive form. Such laws may impair
the ability to transfer beneficial interests in a global Preferred Security.
 
    DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Securities Exchange
Act of
 
                                      S-47

1934, as amended (the "Exchange Act"). DTC holds securities that its
participants ("Participants") deposit with DTC. DTC also facilitates the
settlement among Participants of securities transactions, such as 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 include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations ("Direct Participants"). DTC is owned by a number of its
Direct Participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc., and the National Association of Securities Dealers, Inc. Access
to the DTC system is also available to others such as securities brokers and
dealers, banks and trust companies that clear through or maintain a custodial
relationship with a Direct Participant, either directly or indirectly ("Indirect
Participants"). The rules applicable to DTC and its Participants are on file
with the Commission.
 
    Purchases of Preferred Securities within the DTC system must be made by or
through Direct Participants, which will receive a credit for the Preferred
Securities on DTC's records. The ownership interest of each actual purchaser of
Preferred Securities ("Beneficial Owner") is in turn to be recorded on the
Direct and Indirect Participants' records. Beneficial Owners will not receive
written confirmation from DTC of their purchases, but Beneficial Owners are
expected to receive written confirmations providing details of the transactions,
as well as periodic statements of their holdings, from the Direct or Indirect
Participants through which the Beneficial Owners purchased Preferred Securities.
Transfers of ownership interests in the Preferred Securities are to be
accomplished by entries made on the books of Participants acting on behalf of
Beneficial Owners. Beneficial Owners will not receive certificates representing
their ownership interests in Preferred Securities, except in the event that use
of the book-entry system for the Preferred Securities is discontinued.
 
    To facilitate subsequent transfers, all the Preferred Securities deposited
by Participants with DTC are registered in the name of DTC's nominee, Cede & Co.
The deposit of Preferred Securities with DTC and their registration in the name
of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of
the actual Beneficial Owners of the Preferred Securities. DTC's records reflect
only the identity of the Direct Participants to whose accounts such Preferred
Securities are credited, which may or may not be the Beneficial Owners. The
Participants will remain responsible for keeping account of their holdings on
behalf of their customers.
 
    Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
    Redemption notices shall be sent to Cede & Co. If less than all of the
Preferred Securities are being redeemed, DTC will reduce by lot the amount of
the interest of each Direct Participant in the Preferred Securities to be
redeemed.
 
    Although voting with respect to the Preferred Securities is limited, in
those cases where a vote is required neither DTC nor Cede & Co. will itself
consent or vote with respect to Preferred Securities. Under its usual
procedures, DTC would mail an Omnibus Proxy to the Trust as soon as possible
after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or
voting rights to those Direct Participants to whose accounts the Preferred
Securities are credited on the record date (identified in a listing attached to
the Omnibus Proxy).
 
    Distribution payments on the Preferred Securities will be made to DTC. DTC's
practice is to credit Direct Participants' accounts on the relevant payment date
in accordance with their respective holdings shown on DTC's records unless DTC
has reason to believe that it will not receive payments on such payment date.
Payments by participants to Beneficial Owners will be governed by standing
instructions and customary practices, as in the case with securities held for
the account of customers in bearer form or registered in "street name," and will
be the responsibility of such Participant and not of DTC, the Trust or
 
                                      S-48

any trustee or the Company, subject to any statutory or regulatory requirements
as may be in effect from time to time. Payment of distributions to DTC is the
responsibility of the Trust, disbursement of such payments to Direct
Participants is the responsibility of DTC, and disbursement of such payments to
the Beneficial Owners is the responsibility of Direct and Indirect Participants.
 
    Except as provided herein, a Beneficial Owner in a global Preferred Security
will not be entitled to receive physical delivery of Preferred Securities.
Accordingly, each Beneficial Owner must rely on the procedures of DTC to
exercise any rights under the Preferred Securities.
 
    DTC may discontinue providing its services as securities depositary with
respect to the Preferred Securities at any time by giving reasonable notice to
the Trust. Under such circumstances, in the event that a successor securities
depositary is not obtained, Preferred Securities certificates are required to be
printed and delivered. Additionally, the Regular Trustees (after consultation
with the Company) may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor depositary) with respect to the Preferred
Securities. In that event, certificates for the Preferred Securities will be
printed and delivered.
 
    The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Company and the Trust believe to be
reliable, but the Company and the Trust take no responsibility for the accuracy
thereof.
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
    The Property Trustee, prior to the occurrence of a default with respect to
the Trust Securities and after the curing of all such defaults that may have
occurred, undertakes to perform only such duties as are specifically set forth
in the Declaration and, after default, shall exercise the same degree of care as
a prudent individual would exercise in the conduct of his or her own affairs.
Subject to such provisions, the Property Trustee is under no obligation to
exercise any of the powers vested in it by the Declaration at the request of any
holder of Preferred Securities, unless offered reasonable indemnity by such
holder against the costs, expenses and liabilities which might be incurred
thereby; but the foregoing shall not relieve the Property Trustee, upon the
occurrence of a Declaration Event of Default, from exercising the rights and
powers vested in it by the Declaration. The Property Trustee also serves as the
Subordinated Debentures Trustee under the Debentures Indenture and as the
Preferred Guarantee Trustee under the Preferred Securities Guarantee.
 
REGISTRAR AND TRANSFER AGENT
 
    In the event that the Preferred Securities do not remain in book-entry only
form, the Property Trustee will act as paying agent and may designate an
additional or substitute paying agent at any time. Registration of transfers of
Preferred Securities will be effected without charge by or on behalf of the
Trust, but upon payment (with the giving of such indemnity as the Regular
Trustees may require) in respect of any tax or other government charges which
may be imposed in relation to it. The Trust will not be required to register or
cause to be registered the transfer of Preferred Securities after such Preferred
Securities have been called for redemption.
 
GOVERNING LAW
 
    The Declaration and the Preferred Securities will be governed by, and
construed in accordance with, the internal laws of the State of Delaware.
 
MISCELLANEOUS
 
    The Regular Trustees are authorized and directed to operate the Trust in
such a way so that the Trust will not be deemed to be an "investment company"
required to be registered under the 1940 Act or
 
                                      S-49

characterized for United States federal income tax purposes as other than a
grantor trust. The Company is authorized and directed to conduct its affairs so
that the Subordinated Debentures will be treated as indebtedness of the Company
for United States federal income tax purposes. In this connection, the Regular
Trustees and the Company are authorized to take any action, not inconsistent
with applicable law, the Declaration or the Restated Articles of Incorporation,
as amended, of the Company, that each of the Regular Trustees and the Company
determines in their discretion to be necessary or desirable for such purposes,
as long as such action does not materially and adversely affect the interests of
the holders of the Preferred Securities.
 
    Holders of the Preferred Securities will have no preemptive rights.
 
                                      S-50

               DESCRIPTION OF THE PREFERRED SECURITIES GUARANTEE
 
    Set forth below is a summary of information concerning the Preferred
Securities Guarantee that will be executed and delivered by the Company for the
benefit of the holders from time to time of the Preferred Securities. The
Preferred Securities Guarantee has been qualified as an indenture under the
Trust Indenture Act. The Bank of New York will act as the Preferred Guarantee
Trustee. The terms of the Preferred Securities Guarantee will be those set forth
therein and those made part thereof by the Trust Indenture Act. The following
summary does not purport to be complete and is subject in all respects to the
provisions of, and is qualified in its entirety by reference to, the Preferred
Securities Guarantee (the form of which is filed as an exhibit to the
Registration Statement of which this Prospectus Supplement and the accompanying
Prospectus form a part) and the Trust Indenture Act. The Preferred Securities
Guarantee will be held by the Preferred Guarantee Trustee for the benefit of the
holders of the Preferred Securities.
 
GENERAL
 
    Pursuant to the Preferred Securities Guarantee, the Company will irrevocably
and unconditionally agree to pay in full to the holders of the Preferred
Securities the Guarantee Payments (as defined herein) (without duplication of
amounts theretofore paid by the Trust), to the extent not paid by the Trust,
regardless of any defense, right of set-off or counterclaim that the Trust may
have or assert. The following payments or distributions with respect to the
Preferred Securities to the extent not paid or made by the Trust (the "Guarantee
Payments") will be subject to the Preferred Securities Guarantee (without
duplication): (i) any accrued and unpaid distributions that are required to be
paid on the Preferred Securities, to the extent the Trust has funds available
therefor, (ii) the Redemption Price, which includes all accrued and unpaid
distributions to the date of the redemption, to the extent the Trust has funds
available therefor, with respect to any Preferred Securities called for
redemption by the Trust and (iii) upon a voluntary or involuntary termination,
dissolution or winding-up of the Trust (other than in connection with the
distribution of Subordinated Debentures to the holders of Preferred Securities
in exchange for Preferred Securities), the lesser of (a) the aggregate of the
liquidation amount and all accrued and unpaid distributions on the Preferred
Securities to the date of payment, to the extent the Trust has funds available
therefor, and (b) the amount of assets of the Trust remaining available for
distribution to holders of Preferred Securities in liquidation of the Trust. The
Company's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Company to the holders of Preferred
Securities or by causing the Trust to pay such amounts to such holders.
 
    The Preferred Securities Guarantee will be a full and unconditional
guarantee of the Guarantee Payments with respect to the Preferred Securities
from the time of issuance of the Preferred Securities, but will not apply to the
payment of distributions and other payments on the Preferred Securities when the
Property Trustee does not have sufficient funds in the Property Account to make
such distributions or other payments. If the Company does not make interest
payments on the Subordinated Debentures held by the Property Trustee, the Trust
will not make distributions on the Preferred Securities issued by the Trust and
will not have funds available therefor. See "Risk Factors--Rights under the
Preferred Securities Guarantee" and "Description of the Subordinated
Debentures--Certain Covenants."
 
    The Company has also agreed separately to guarantee the obligations of the
Trust with respect to the Common Securities (the "Common Securities Guarantee")
to the same extent as the Preferred Securities Guarantee, except that upon the
occurrence and during the continuation of a Debentures Indenture Event of
Default, holders of Preferred Securities shall have priority over holders of
Common Securities with respect to distributions and payments on liquidation,
redemption or otherwise.
 
    For information concerning the requirement that the Preferred Securities be
disposed of by holders or beneficial owners under certain circumstances, see
"Description of the Preferred Securities--Mandatory Disposition Pursuant to
Gaming Laws."
 
                                      S-51

CERTAIN COVENANTS OF THE COMPANY
 
    In the Preferred Securities Guarantee, the Company will covenant that, so
long as the Preferred Securities remain outstanding, if there shall have
occurred and is continuing any event that constitutes an event of default under
the Preferred Securities Guarantee or the Declaration, then (a) the Company
shall not declare or pay any dividend on, or make any distribution with respect
to, or redeem, purchase, acquire or make a liquidation payment with respect to,
any of its capital stock, (b) the Company shall not make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities issued by the Company which rank PARI PASSU with or junior to
the Subordinated Debentures and (c) the Company shall not make any guarantee
payments (other than pursuant to the Preferred Securities Guarantee) with
respect to the foregoing. However, the foregoing restriction will not apply to
any dividend, redemption, liquidation, interest, principal or guarantee payments
by the Company where the payment is made by way of securities (including capital
stock) that rank junior to the securities on which such dividend, redemption,
interest, principal or guarantee payment is being made.
 
AMENDMENTS AND ASSIGNMENT
 
    Except with respect to any changes which do not materially adversely affect
the rights of holders of Preferred Securities (in which case no consent will be
required), the Preferred Securities Guarantee may be amended only with the prior
approval of the holders of not less than a majority in liquidation amount of the
outstanding Preferred Securities. The manner of obtaining any such approval of
holders of the Preferred Securities is set forth under "Description of the
Preferred Securities--Voting Rights." All guarantees and agreements contained in
the Preferred Securities Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of the Company and shall inure to the
benefit of the Preferred Guarantee Trustee and the holders of the Preferred
Securities then outstanding.
 
TERMINATION OF THE PREFERRED SECURITIES GUARANTEE
 
    The Preferred Securities Guarantee will terminate and be of no further force
and effect as to the Preferred Securities upon full payment of the Redemption
Price of all Preferred Securities, or upon distribution of the Subordinated
Debentures to the holders of the Trust Securities, and will terminate completely
upon full payment of the amounts payable upon liquidation of the Trust. The
Preferred Securities Guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any holder of Preferred
Securities must repay to the Trust or the Company, or their successors, any sums
paid to them under such Preferred Securities or the Preferred Securities
Guarantee.
 
EVENTS OF DEFAULT
 
    An event of default under the Preferred Securities Guarantee will occur upon
the failure of the Company to perform any of its payment or other obligations
thereunder.
 
    The holders of a majority in liquidation amount of the Preferred Securities
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Preferred Guarantee Trustee in respect of the
Preferred Securities Guarantee or to direct the exercise of any trust or power
conferred upon the Preferred Guarantee Trustee under the Preferred Securities
Guarantee. If the Preferred Guarantee Trustee fails to enforce the Preferred
Securities Guarantee, any holder of Preferred Securities may institute a legal
proceeding directly against the Company to enforce the Preferred Guarantee
Trustee's rights under the Preferred Securities Guarantee, without first
instituting a legal proceeding against the Trust, the Preferred Guarantee
Trustee or any other person or entity. In addition, any record holder of
Preferred Securities shall have the right, which is absolute and unconditional,
to proceed directly against the Company to obtain Guarantee Payments, without
first waiting to determine if the Preferred Guarantee Trustee has enforced the
Preferred Security Guarantee or instituting a legal proceeding against the
Trust, the Preferred Guarantee Trustee or any other person or entity.
 
                                      S-52

STATUS OF THE PREFERRED SECURITIES GUARANTEE
 
    The Company's obligations under the Preferred Securities Guarantee to make
the Guarantee Payments will constitute an unsecured obligation of the Company
and will rank (i) subordinate and junior in right of payment to all other
liabilities of the Company, including the Subordinated Debentures, except those
liabilities of the Company made PARI PASSU or subordinate by their terms, (ii)
PARI PASSU with the most senior preferred stock issued from time to time by the
Company and with any guarantee now or hereafter entered into by the Company in
respect of any preferred stock of any subsidiary or affiliate of the Company and
(iii) senior to the Company's common stock. The terms of the Preferred
Securities provide that each holder of Preferred Securities by acceptance
thereof agrees to the subordination provisions and other terms of the Preferred
Securities Guarantee.
 
    The Preferred Securities Guarantee will constitute a guarantee of payment
and not of collection (that is, the guaranteed party may institute a legal
proceeding directly against the guarantor to enforce its rights under the
guarantee without instituting a legal proceeding against any other person or
entity). The Preferred Securities Guarantee will be deposited with the Preferred
Guarantee Trustee to be held for the benefit of the holders of the Preferred
Securities. Except as otherwise noted herein, the Preferred Guarantee Trustee
has the right to enforce the Preferred Securities Guarantee on behalf of the
holders of the Preferred Securities. The Preferred Securities Guarantee will not
be discharged except by payment of the Guarantee Payments in full (without
duplication of amounts theretofore paid by the Trust) or upon distribution of
the Subordinated Debentures to the holders of the Trust Securities.
 
    The Company's obligations under the Preferred Securities Guarantee, taken
together with its obligations under the Declaration, the Subordinated Debentures
and the Debentures Indenture, in the aggregate provide a full and unconditional
guarantee by the Company of payments due on the Preferred Securities.
 
INFORMATION CONCERNING THE PREFERRED GUARANTEE TRUSTEE
 
    The Preferred Guarantee Trustee, prior to the occurrence of a default with
respect to the Preferred Securities Guarantee and after the curing of all such
defaults that may have occurred, undertakes to perform only such duties as are
specifically set forth in the Preferred Securities Guarantee and, after default,
shall exercise the same degree of care as a prudent individual would exercise in
the conduct of his or her own affairs. Subject to such provisions, the Preferred
Guarantee Trustee is under no obligation to exercise any of the powers vested in
it by the Preferred Securities Guarantee at the request of any holder of
Preferred Securities, unless offered reasonable indemnity against the costs,
expenses and liabilities which might be incurred thereby; but the foregoing
shall not relieve the Preferred Guarantee Trustee, upon the occurrence of an
event of default under the Preferred Securities Guarantee, from exercising the
rights and powers vested in it by the Preferred Securities Guarantee. The
Preferred Guarantee Trustee also serves as Property Trustee under the
Declaration and as Subordinated Debentures Trustee under the Debentures
Indenture.
 
GOVERNING LAW
 
    The Preferred Securities Guarantee will be governed by, and construed in
accordance with, the internal laws of the State of New York.
 
                                      S-53

                   DESCRIPTION OF THE SUBORDINATED DEBENTURES
 
    Set forth below is a description of the terms of the Subordinated
Debentures. The following description does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, the Debentures
Indenture, to be dated as of            , 1998, as supplemented by a First
Supplemental Indenture (as so supplemented, the "Debentures Indenture"), between
the Company and The Bank of New York, as Trustee (the "Subordinated Debentures
Trustee"), which (or the respective forms of which) are filed as exhibits to the
Registration Statement of which this Prospectus Supplement and the accompanying
Prospectus form a part. The terms of the Subordinated Debentures will include
those stated in the Debentures Indenture (which has been qualified under the
Trust Indenture Act) and those made a part of the Debentures Indenture by
reference to the Trust Indenture Act. Certain capitalized terms used herein are
defined in the Debentures Indenture.
 
    Under certain circumstances involving the termination of the Trust following
the occurrence of a Special Event, Subordinated Debentures may be distributed to
the holders of Trust Securities in liquidation of the Trust. See "Description of
the Preferred Securities--Special Event Redemption or Distribution."
 
    If the Subordinated Debentures are distributed to the holders of the Trust
Securities, the Company will use its best efforts to have the Subordinated
Debentures listed on the New York Stock Exchange or on such other exchange as
the Preferred Securities are then listed.
 
GENERAL
 
    The Subordinated Debentures will be issued as unsecured subordinated debt
securities under the Debentures Indenture. The Subordinated Debentures will be
limited in aggregate principal amount to $     , such amount being the sum of
the aggregate liquidation amount of the Preferred Securities and the capital
contributed by the Company in exchange for the Common Securities.
 
    The Subordinated Debentures are not subject to any sinking fund provision.
The entire principal amount of the Subordinated Debentures will mature and
become due and payable, together with any accrued and unpaid interest thereon,
on            ,    .
 
    If Subordinated Debentures are distributed to holders of the Trust
Securities in liquidation of such holders' interests in the Trust, such
Subordinated Debentures will initially be issued as a Global Security (as
defined below). As described herein, under certain limited circumstances,
Subordinated Debentures may be issued in certificated form in exchange for a
Global Security. See "--Book Entry and Settlement" below. In the event
Subordinated Debentures are issued in certificated form, such Subordinated
Debentures will be in denominations of $1,000 and integral multiples thereof and
may be transferred or exchanged at the offices described below. Payments on
Subordinated Debentures issued as a Global Security will be made to the
depositary for the Subordinated Debentures. In the event Subordinated Debentures
are issued in certificated form, principal and interest will be payable, the
transfer of the Subordinated Debentures will be registrable and Subordinated
Debentures will be exchangeable for Subordinated Debentures of other
denominations of a like aggregate principal amount at the corporate trust office
of the Subordinated Debentures Trustee in New York, New York; PROVIDED, HOWEVER,
that payment of interest may be made at the option of the Company by check
mailed to the address of the persons entitled thereto.
 
    The Debentures Indenture does not contain provisions that afford holders of
the Subordinated Debentures protection in the event of a highly leveraged
transaction involving the Company or a decline in the credit quality of the
Company resulting from a change of control transaction.
 
SUBORDINATION
 
    The payment of the principal of, premium, if any, and interest on the
Subordinated Debentures will be subordinated in right of payment, as described
below, to the prior payment in full of all current and future Senior
Indebtedness.
 
                                      S-54

    The Debentures Indenture will provide that in the event of any insolvency or
bankruptcy case or proceeding, or any receivership, liquidation, reorganization
or other similar case or proceeding in connection therewith, relating to the
Company, or any distribution of assets of the Company pursuant to liquidation,
dissolution or other winding-up or reorganization of the Company, whether
voluntary or involuntary, or any assignment for the benefit of creditors or
other marshalling of assets or liabilities of the Company, all current and
future Senior Indebtedness must be paid in full before any payment or
distribution is made on account of the principal of, premium, if any, or
interest on the Subordinated Debentures. Upon maturity of any current or future
Senior Indebtedness by lapse of time, acceleration or otherwise, payment in full
must be made on such Senior Indebtedness before any payment is made on or in
respect of the Subordinated Debentures. During the continuance of any event of
default with respect to any current or future Senior Indebtedness entitling the
holders thereof to accelerate the maturity thereof, or if such event of default
would be caused by any payment upon or in respect of the Subordinated
Debentures, no payment may be made by the Company upon or in respect of the
Subordinated Debentures.
 
    In the event that, notwithstanding the foregoing, the Company makes any
payment or distribution to the Subordinated Debentures Trustee or any holders of
any Subordinated Debentures prohibited by the subordination provision of the
Debentures Indenture, then such payment or distribution will be required to be
paid over and delivered to the holders (or their representative) of Senior
Indebtedness.
 
    By reason of such subordination, in the event of liquidation or insolvency,
creditors of the Company who are holders of Senior Indebtedness may recover
more, ratably, than the holders of the Subordinated Debentures and funds that
would be otherwise payable to the holders of the Subordinated Debentures will be
paid to the holders of Senior Indebtedness to the extent necessary to pay the
Senior Indebtedness in full, and the Company may be unable to meet its
obligation fully with respect to the Subordinated Securities.
 
    The term "Credit Facility", as defined in the Debentures Indenture, means
the Amended and Restated Loan Agreement dated as of May 23, 1997 among the
Company, as borrower, Bank of America National Trust and Savings Association, as
Administrative Agent, and the lenders which are or become parties from time to
time thereto, as amended by Amendment No. 1 thereto dated as of October 3, 1997
and Amendment No. 2 thereto dated as of May 15, 1998, together with the related
documents thereto (including, without limitation, any guarantee agreements and
security documents), in each case as such agreements may be amended (including
without limitation any amendment and restatement thereof), supplemented or
otherwise modified from time to time, including without limitation any agreement
extending the maturity of, refinancing or otherwise restructuring (including
adding guarantors) all or any portion of the Indebtedness under such agreement
or any successor agreement or increasing the credit available thereunder.
 
    The term "Senior Indebtedness," as defined in the Debentures Indenture,
means the principal, premium, if any, and interest on any Indebtedness of the
Company, whenever created, incurred, assumed or guaranteed, unless, in the case
of any particular Indebtedness, the instrument creating or evidencing the same
or pursuant to which the same is outstanding expressly provides that such
Indebtedness shall not be senior in right of payment to the Subordinated
Debentures. Without limiting the foregoing, Senior Indebtedness shall include
(i) any payment or payment obligation in respect of (a) Indebtedness of the
Company for money borrowed, including under the Credit Facility, together with
any other amounts due on or in connection with the Indebtedness of the Company
under the Credit Facility, and (b) Indebtedness evidenced by securities,
debentures, bonds, notes or other similar instruments issued by the Company,
including all Indebtedness currently outstanding under indentures with various
trustees; (ii) all Interest Rate Protection Obligations of the Company; (iii)
all Capital Lease Obligations of the Company; (iv) all obligations of the
Company issued or assumed as the deferred purchase price of property, all
conditional sale obligations of the Company and all obligations of the Company
under any title retention agreement (but excluding any obligations in respect of
any trade accounts payable incurred for the purchase of goods or materials, or
for services obtained, in the ordinary course of business); (v) all obligations
of the
 
                                      S-55

Company for the reimbursement on any letter of credit, banker's acceptance,
security purchase facility or similar credit transaction; (vi) the 6 3/4% Senior
Subordinated Notes of the Company Due 2003 and the 7 5/8% Senior Subordinated
Debentures of the Company Due 2013; the Senior Secured Debt Securities, the
Senior Unsecured Debt Securities, the 6.45% Senior Notes of the Company Due
2006, the 7.0% Debentures of the Company Due 2036 and the 6.70% Debentures of
the Company Due 2096; (vii) all obligations of the type referred to in clauses
(i) through (vi) above of other persons for the payment of which the Company is
responsible or liable as obligor, guarantor or otherwise; and (viii) all
obligations of the type referred to in clauses (i) through (vii) above of other
persons secured by any lien on any property or asset of the Company (whether or
not such obligation is assumed by the Company), except for any such Indebtedness
that is by its terms subordinated to or PARI PASSU with the Subordinated
Debentures, as the case may be. Such Senior Indebtedness shall continue to be
Senior Indebtedness and be entitled to the benefits of the subordination
provisions irrespective of any amendment, modification or waiver of any term of
such Senior Indebtedness.
 
    The Debentures Indenture does not limit the aggregate amount of Senior
Indebtedness which may be issued by the Company. As of April 30, 1998, Senior
Indebtedness of the Company aggregated approximately $1.6 billion. In addition,
because the Company is a holding company, its obligations under the Preferred
Securities Guarantee and the Subordinated Debentures will be effectively
subordinated to all existing and future liabilities of the Company's
subsidiaries. At April 30, 1998, the subsidiaries of the Company had total
indebtedness outstanding and other liabilities of approximately $187 million
(excluding, in each case, indebtedness and other liabilities owed to the Company
and other affiliates, guaranteed indebtedness of subsidiaries that is included
in Senior Indebtedness and deferred income taxes and other deferred credits).
 
CERTAIN COVENANTS
 
    If (i) there shall have occurred and be continuing any event that
constitutes a Debentures Indenture Event of Default or (ii) the Company shall be
in default with respect to its payment of any obligations under the Preferred
Securities Guarantee or the Common Securities Guarantee, and such default shall
be continuing then (a) the Company shall not declare or pay any dividend on,
make any distributions with respect to, or redeem, purchase or make a
liquidation payment with respect to, any of its capital stock, (b) the Company
shall not make any payment of interest, principal or premium, if any, on or
repay, repurchase or redeem any debt securities issued by the Company which rank
PARI PASSU with or junior to the Subordinated Debentures and (c) the Company
shall not make any guarantee payments (other than pursuant to the Preferred
Securities Guarantee) with respect to the foregoing.
 
    If the Company shall have given notice of its election of an Extension
Period as provided in the Debentures Indenture and such period, or any extension
thereof, shall be continuing, then during the term of such Extension Period (a)
the Company shall not declare or pay any dividend on, make any distributions
with respect to, or redeem, purchase or make a liquidation payment with respect
to, any of its capital stock, (b) the Company shall not make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities issued by the Company which rank PARI PASSU with or junior to
the Subordinated Debentures and (c) the Company shall not make any guarantee
payments (other than pursuant to the Preferred Securities Guarantee) with
respect to the foregoing.
 
    Notwithstanding the foregoing restrictions, the Company will be permitted,
in any event, to make dividend, redemption, liquidation and guarantee payments
on capital stock, and interest, principal, redemption and guarantee payments on
debt securities issued by the Company ranking PARI PASSU with or junior to
Subordinated Debentures, where the payment is made by way of securities
(including capital stock) that rank junior to the securities on which such
payment is being made.
 
    For so long as the Trust Securities remain outstanding, the Company will
covenant (i) to directly or indirectly maintain 100% direct or indirect
ownership of the Common Securities of the Trust; PROVIDED, HOWEVER, that any
permitted successor of the Company under the Debentures Indenture may succeed to
the
 
                                      S-56

Company's ownership of such Common Securities, (ii) not to cause, as sponsor of
the Trust, or to permit, as holder of the Common Securities, the termination,
dissolution or winding-up of the Trust, except in connection with a distribution
of the Subordinated Debentures as provided in the Declaration and in connection
with certain mergers, consolidations or amalgamations, (iii) to use its
reasonable efforts to cause the Trust (a) to remain a statutory business trust,
except in connection with the distribution of Subordinated Debentures to the
holders of Trust Securities in liquidation of the Trust, the redemption of all
of the Trust Securities of the Trust, or certain mergers, consolidations or
amalgamations, each as permitted by the Declaration, and (b) to otherwise
continue to be classified as a grantor trust for United States federal income
purposes and (iv) to use reasonable efforts to cause each holder of Trust
Securities to be treated as owning an undivided beneficial interest in the
Subordinated Debentures.
 
MANDATORY DISPOSITION PURSUANT TO GAMING LAWS
 
    The Debentures Indenture will provide that each holder and beneficial owner
of Subordinated Debentures, by accepting or otherwise acquiring an interest in
the Subordinated Debentures, shall be deemed to have agreed that if the Gaming
Authority of any jurisdiction in which the Company or any of its subsidiaries
(or any joint venture in which the Company or a subsidiary of the Company is a
participant) now or hereafter conducts or proposes to conduct gaming requires
that a person who is a holder or beneficial owner of Subordinated Debentures
must be licensed, qualified or found suitable, or comply with any other
requirement under applicable Gaming Laws, such holder or beneficial owner shall
apply for a license, qualification or a finding of suitability or comply with
such other requirement, as the case may be, within the prescribed time period.
If such holder or beneficial owner fails to apply to be, or fails to become,
licensed or qualified, is found unsuitable or fails to comply with any other
requirement, as the case may be (a "failure of compliance"), then the Company
shall have the right, at its option (i) to require such person to dispose of its
Subordinated Debentures or beneficial interest therein within 30 days of receipt
of notice of the Company's election or such earlier date as may be requested or
prescribed by the Gaming Authority or (ii) to redeem such Subordinated
Debentures (which redemption may be less than 30 days following the notice of
redemption if so requested or prescribed by the Gaming Authority) at a
redemption price equal to the lesser of (A) such person's cost, (B) 100% of the
principal amount thereof, plus accrued and unpaid interest to the earlier of the
redemption date and the date of any failure of compliance, or (C) such other
amount as may be required by applicable law or by order of any Gaming Authority.
The Company shall notify the Subordinated Debentures Trustee in writing of any
such redemption as soon as practicable. The Company shall not be responsible for
any costs or expenses any such holder or beneficial owner may incur in
connection with its application for a license, qualification or a finding of
suitability or its compliance with any other requirement of a Gaming Authority.
The Debentures Indenture will also provide that immediately upon the imposition
by a Gaming Authority of a requirement that a holder or beneficial owner dispose
of Subordinated Debentures, such holder or beneficial owner shall, to the extent
required by applicable Gaming Laws, have no further right (i) to exercise,
directly or indirectly, through any trustee, nominee or any other person or
entity, any right conferred by the Subordinated Debentures or (ii) to receive
any interest, dividends or any other distributions or payments with respect to
the Subordinated Debentures or any remuneration in any form with respect to the
Subordinated Debentures from the Company or the Subordinated Debentures Trustee,
except the redemption price referred to above.
 
OPTIONAL REDEMPTION
 
    The Company shall have the right to redeem the Subordinated Debentures, in
whole or in part, from time to time, on or after            ,    , or at any
time in certain circumstances upon the occurrence of a Tax Event as described
under "Description of the Preferred Securities--Special Event Redemption or
Distribution," upon not less than 30 nor more than 60 days' notice, at a
redemption price equal to 100% of the principal amount to be redeemed plus any
accrued and unpaid interest to the redemption date. If a partial redemption of
the Preferred Securities resulting from a partial redemption of the Subordinated
Debentures would result in the delisting of the Preferred Securities, the
Company may only redeem the Subordinated Debentures in whole.
 
                                      S-57

INTEREST
 
    Each Subordinated Debenture shall bear interest at the rate of      % per
annum from            , 1998, payable quarterly in arrears on            ,
           ,            and            of each year (each, an "Interest Payment
Date"), commencing            , 1998, to the person in whose name such
Subordinated Debenture is registered, subject to certain exceptions, at the
close of business on the Business Day next preceding such Interest Payment Date.
The distribution payable on            , 1998, which will be calculated at the
above rate and based on a period that is shorter than a full quarter, will be in
the amount of $     per Preferred Security. In the event the Subordinated
Debentures are distributed to holders of the Trust Securities in liquidation of
such holders' interests in the Trust and such Subordinated Debentures shall not
thereafter continue to remain in book-entry only form, the Company shall have
the right to select record dates which shall be not less than fifteen days prior
to each Interest Payment Date.
 
    The amount of interest payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months. The amount of interest payable for
any period shorter than a full quarterly period will be computed on the basis of
the actual number of days elapsed in such 90-day quarter. In the event that any
date on which interest is payable on the Subordinated Debentures is not a
Business Day, then payment of the interest payable on such date will be made on
the next succeeding day which 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 succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
    The Company shall have the right at any time, and from time to time, during
the term of the Subordinated Debentures to defer payments of interest by
extending the interest payment period for a period not exceeding 20 consecutive
quarters, at the end of which Extension Period the Company shall pay all
interest then accrued and unpaid (including any Additional Interest), together
with interest thereon at the rate specified for the Subordinated Debentures to
the extent permitted by applicable law; PROVIDED, HOWEVER, that, during any such
Extension Period, (a) the Company shall not declare or pay any dividend on, make
any distributions with respect to, or redeem, purchase or make a liquidation
payment with respect to, any of its capital stock, (b) the Company shall not
make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities issued by the Company which rank PARI
PASSU with or junior to the Subordinated Debentures and (c) the Company shall
not make any guarantee payments (other than pursuant to the Preferred Securities
Guarantee) with respect to the foregoing; PROVIDED, HOWEVER, the foregoing
restriction will not apply to any dividend, redemption, liquidation, interest,
principal or guarantee payments by the Company where the payment is made by way
of securities (including capital stock) that rank junior to the securities on
which such dividend, redemption, interest, principal or guarantee payment is
being made. Prior to the termination of any such Extension Period, the Company
may further defer payments of interest by extending the interest payment period,
provided that such Extension Period together with all such previous and further
extensions thereof may not exceed 20 consecutive quarters or extend beyond the
maturity of the Subordinated Debentures. Upon the termination of any Extension
Period and the payment of all amounts then due, the Company may select a new
Extension Period, as if no Extension Period had previously been declared,
subject to the above requirements. No interest on the Subordinated Debentures
during an Extension Period, except at the end thereof, shall be due and payable.
 
    The Company takes the position that the Subordinated Debentures will be
issued with OID at the time of their original issuance and that each U.S. holder
of Preferred Securities will be required to include in gross income such
holder's allocable share of the interest paid on the Subordinated Debentures as
OID. As a result, holders of Preferred Securities will recognize income for
United States federal income tax purposes in advance of the receipt of cash and
will not receive cash from the Trust related to such income if such holder
disposes of such holder's Preferred Securities prior to the record date for the
date on which
 
                                      S-58

distribution of such amounts are made. If the Property Trustee shall be the sole
holder of the Subordinated Debentures, the Company shall give the Regular
Trustees and the Property Trustee notice of its selection of an Extension Period
one Business Day prior to the earlier of (i) the next succeeding date on which
distributions on the Preferred Securities are payable or (ii) the date the Trust
is required to give notice to any national securities exchange or other
applicable self-regulatory organization or to holders of the Preferred
Securities of the record date or the date such distribution is payable, but in
any event not less than one Business Day prior to such record date. The Regular
Trustees shall give notice of the Company's selection of such Extension Period
to the holders of the Preferred Securities. If the Property Trustee shall not be
the sole holder of the Subordinated Debentures, the Company shall give the
holders of the Subordinated Debentures notice of its selection of such Extension
Period ten Business Days prior to the earlier of (i) the relevant Interest
Payment Date or (ii) the date the Company is required to give notice to any
national securities exchange or other applicable self-regulatory organization or
to holders of the Subordinated Debentures of the record or payment date of such
related interest payment, but in any event at least two Business Days before
such record date.
 
ADDITIONAL INTEREST
 
    If at any time the Trust shall be required to pay any taxes, duties,
assessments or governmental charges of whatever nature (other than withholding
taxes) imposed by the United States, or any other taxing authority, then, in any
such case, the Company will pay as additional interest ("Additional Interest")
such additional amounts as shall be required so that the net amounts received
and retained by the Trust after paying any such taxes, duties, assessments or
other governmental charges will be equal to the amounts the Trust would have
received had no such taxes, duties, assessments or other governmental charges
been imposed.
 
DEBENTURES INDENTURE EVENTS OF DEFAULT
 
    In case any Event of Default shall occur under the Debentures Indenture and
be continuing, the Property Trustee, as the holder of the Subordinated
Debentures, will have the right to declare the principal of and the interest on
the Subordinated Debentures (including Additional Interest, if any) and any
other amounts payable under the Debentures Indenture to be forthwith due and
payable and to enforce its other rights as a creditor with respect to the
Subordinated Debentures.
 
    The Debentures Indenture provides that any one or more of the following
described events, which has occurred and is continuing, constitutes an "Event of
Default" with respect to the Subordinated Debentures:
 
        (a) failure for 30 days to pay interest on the Subordinated Debentures,
    including any Additional Interest in respect thereof, when due; provided,
    however, that a valid extension of the interest payment period by the
    Company shall not constitute a default in the payment of interest for this
    purpose; or
 
        (b) failure to pay principal or premium, if any, on the Subordinated
    Debentures when due whether at maturity, upon earlier redemption or
    otherwise; or
 
        (c) failure to observe or perform any other covenant (other than those
    specifically relating to another series of subordinated debt securites)
    contained in the Debentures Indenture for 90 days after written notice to
    the Company from the Subordinated Debentures Trustee or the holders of at
    least 25% in principal amount of the outstanding Subordinated Debentures; or
 
        (d) certain events of bankruptcy, insolvency or reorganization of the
    Company; or
 
        (e) the voluntary or involuntary termination, dissolution or winding-up
    of the Trust, except in connection with the distribution of Subordinated
    Debentures to the holders of Trust Securities in liquidation of the Trust,
    the redemption of all outstanding Trust Securities of the Trust and certain
    mergers, consolidations or amalgamations permitted by the Declaration.
 
                                      S-59

    The holders of a majority in aggregate outstanding principal amount of the
Subordinated Debentures have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Subordinated
Debentures Trustee. The Subordinated Debentures Trustee or the holders of not
less than 25% in aggregate outstanding principal amount of the Subordinated
Debentures may declare the principal due and payable immediately on default, but
the holders of a majority in aggregate outstanding principal amount may annul
such declaration and waive the default if the default has been cured and a sum
sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration has been deposited with the Subordinated
Debentures Trustee.
 
    The holders of a majority in aggregate outstanding principal amount of the
Subordinated Debentures affected thereby may, on behalf of the holders of all
the Subordinated Debentures, waive any past default, except (i) a default in the
payment of principal or interest, including Additional Interest (unless such
default has been cured and a sum sufficient to pay all matured installments of
interest and principal due otherwise than by acceleration and any applicable
premium has been deposited with the Subordinated Debentures Trustee), or (ii) a
default in the covenant of the Company not to declare or pay dividends on, or
make distributions with respect to, or redeem, purchase or acquire any of its
capital stock during an Extension Period. A Debentures Indenture Event of
Default also constitutes a Declaration Event of Default. The holders of
Preferred Securities in certain circumstances have the right to direct the
Property Trustee to exercise its rights as the holder of the Subordinated
Debentures. See "Description of the Preferred Securities--Declaration Events of
Default" and "--Voting Rights."
 
    In addition, if an Event of Default under the Debentures Indenture results
from the failure of the Company to pay principal of or interest on the
Subordinated Debentures when due, during the continuance of such an event of
default a holder of Preferred Securities may immediately institute a legal
proceeding directly against the Company to obtain payment of such principal or
interest on Subordinated Debentures having a principal amount equal to the
aggregate liquidation amount of the Preferred Securities owned of record by such
holder.
 
BOOK-ENTRY AND SETTLEMENT
 
    If distributed to holders of Preferred Securities in connection with the
voluntary or involuntary termination, dissolution or winding-up of the Trust as
a result of the occurrence of a Special Event, the Subordinated Debentures will
be issued in the form of one or more global certificates (each, a "Global
Security") registered in the name of the depositary or its nominee. Except under
the limited circumstances described below, Subordinated Debentures represented
by the Global Security will not be exchangeable for, and will not otherwise be
issuable as, Subordinated Debentures in definitive 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 require that certain purchasers of securities
take physical delivery of such securities in definitive form. Such 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 Subordinated
Debentures in definitive form and will not be considered the Holders (as defined
in the Debentures Indenture) thereof for any purpose under the Debentures
Indenture, and no Global Security representing Subordinated Debentures 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 and, 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 Debentures Indenture.
 
                                      S-60

    If Subordinated Debentures are distributed to holders of Preferred
Securities in liquidation of such holders' interests in the Trust, DTC will act
as securities depositary for the Subordinated Debentures. For a description of
DTC and the specific terms of the depository arrangements, see "Description of
the Preferred Securities--Book-Entry Only Issuance--The Depository Trust
Company." The description therein of DTC's book-entry system and DTC's practices
as they relate to purchases, transfers, notices and payments with respect to the
Preferred Securities apply in all material respects to any debt obligations
represented by one or more Global Securities held by DTC. The Company may
appoint a successor to DTC or any successor depositary in the event DTC or such
successor depositary is unable or unwilling to continue as depositary.
 
    None of the Company, the Trust, the Subordinated Debentures Trustee, any
paying agent and any other agent of the Company or the Subordinated Debentures
Trustee will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests in a
Global Security for such Subordinated Debentures or for maintaining, supervising
or reviewing any records relating to such beneficial ownership interests.
 
    A Global Security shall be exchangeable for Subordinated Debentures
registered in the names of persons other than the depositary or its nominee only
if (i) the depositary notifies the Company that it is unwilling or unable to
continue as a depositary for such Global Security and no successor depositary
shall have been appointed, or if at any time the depositary ceases to be
registered or in good standing under the Exchange Act (or other applicable
statute or regulation) at a time when the depositary is required to be so
registered to act as such depositary and no successor depositary shall have been
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, or (ii) the Company in its sole discretion
determines that such Global Security shall be so exchangeable. Any Global
Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Subordinated Debentures registered in such names as the
depositary shall direct. It is expected that such instructions will be based
upon directions received by the depositary from its Participants with respect to
ownership of beneficial interests in such Global Security.
 
    In the event the Subordinated Debentures are not represented by one or more
Global Securities, certificates evidencing Subordinated Debentures may be
presented for registration of transfer (with the form of transfer endorsed
thereon duly executed) or exchange, at the office of the Registrar (as defined
in the Debentures Indenture) or at the office of any transfer agent designated
by the Company for such purpose with respect to the Subordinated Debentures,
without service charge and upon payment of any taxes and other governmental
charges as described in the Debentures Indenture. Such transfer or exchange will
be effected upon the register maintained by the Registrar (as defined in the
Debentures Indenture) for the Subordinated Debentures or such transfer agent, as
the case may be, being satisfied with the documents of title and identity of the
person making the request. The Company has appointed the Subordinated Debentures
Trustee as Registrar with respect to the Subordinated Debentures. The Company
may at any time rescind the designation of any such transfer agent or approve a
change in the location through which any such transfer agent acts, except that
the Company will be required to maintain a transfer agent at the place of
payment. The Company may at any time designate additional transfer agents with
respect to the Subordinated Debentures.
 
    In the event of any redemption in part, the Company shall not be required to
(i) issue, exchange or register the transfer of Subordinated Debentures during a
period beginning at the opening of business 15 days before the day of the
mailing of a notice of redemption of less than all of the Subordinated
Debentures and ending at the close of business on the date of such mailing or
(ii) register the transfer of or exchange any Subordinated Debentures so
selected for redemption, in whole or in part, except the unredeemed portion of
any Subordinated Debentures being redeemed in part.
 
                                      S-61

PAYMENT AND PAYING AGENTS
 
    Payment of principal of and premium, if any, on the Subordinated Debentures
will be made only against surrender to the Paying Agent (as defined in the
Debentures Indenture) of the Subordinated Debentures. Principal of and premium,
if any, and interest on Subordinated Debentures will be payable, subject to any
applicable laws and regulations, at the office of such Paying Agent or Paying
Agents as the Company may designate from time to time, except that at the option
of the Company payment of any interest may be made by check mailed to the
address of the person entitled thereto as such address shall appear in the
Register with respect to the Subordinated Debentures. Payment of interest on the
Subordinated Debentures on any Interest Payment Date will be made to the person
in whose name the Subordinated Debenture (or predecessor security) is registered
at the close of business on the Regular Record Date (as defined in the
Debentures Indenture) for such interest payment.
 
    The Company will initially act as Paying Agent with respect to the
Subordinated Debentures except that, if the Subordinated Debentures are
distributed to the holders of the Preferred Securities in liquidation of such
holders' interests in the Trust, the Subordinated Debentures Trustee will act as
the Paying Agent. The Company may at any time designate additional Paying Agents
or rescind the designation of any Paying Agents or approve a change in the
office through which any Paying Agent acts, except that the Company will be
required to maintain a Paying Agent at the place of payment.
 
    All moneys paid by the Company to a Paying Agent for the payment of the
principal of, premium, if any, or interest, if any, on the Subordinated
Debentures which remain unclaimed at the end of two years after such principal,
premium or interest shall have become due and payable will be repaid to the
Company, and the holder of such Subordinated Debentures will thereafter look
only to the Company for payment thereof.
 
MODIFICATION OF THE DEBENTURES INDENTURE
 
    The Debentures Indenture contains provisions permitting the Company and the
Subordinated Debentures Trustee, with the consent of the holders of not less
than a majority in principal amount of the Subordinated Debentures, to modify
the Debentures Indenture or any supplemental indenture affecting that series or
the rights of the holders of the Subordinated Debentures; PROVIDED, HOWEVER,
that no such modification may, without the consent of the holder of each
outstanding Subordinated Debenture affected thereby, (i) extend the fixed
maturity of the Subordinated Debentures, or reduce the principal amount thereof,
or reduce the rate or extend the time of payment of interest thereon, or reduce
any premium payable upon the redemption thereof, without the consent of the
holder of the Subordinated Debentures so affected or (ii) reduce the percentage
of Subordinated Debentures the holders of which are required to consent to any
such supplemental indenture, without the consent of the holders of each
Subordinated Debenture then outstanding and affected thereby.
 
    In addition, the Company and the Subordinated Debentures Trustee may
execute, without the consent of holders of the Subordinated Debentures, any
supplemental indenture for certain other usual purposes including the creation
of any new series of subordinated debt securities.
 
SUCCESSOR CORPORATION
 
    The Company may not consolidate with or merge into, or transfer its
properties and assets substantially as an entirety to, another corporation
unless (i) the successor corporation, which shall be a corporation organized
under the laws of the United States or a State thereof, assumes by supplemental
indenture all the obligations of the Company under the Subordinated Debentures
and the Debentures Indenture, and (ii) after giving effect to such transaction,
no Debentures Indenture Event of Default shall have occurred and be continuing.
The Debentures Indenture does not otherwise contain any covenant which restricts
the ability of the Company to merge or consolidate with or into any other
corporation, sell or convey all or substantially all of its assets to any
person, firm or corporation or otherwise engage in restructuring transactions.
 
                                      S-62

DEFEASANCE AND DISCHARGE
 
    Under the terms of the Debentures Indenture, the Company will be discharged
from any and all obligations in respect of the Subordinated Debentures (except
in each case for certain obligations with respect to denominations and
provisions for payment of the Subordinated Debentures and obligations to
register the transfer or exchange of Subordinated Debentures, replace stolen,
lost or mutilated Subordinated Debentures, maintain paying agencies and hold
moneys for payment in trust) if the Company (i) deposits with the Subordinated
Debentures Trustee, in trust, moneys or governmental obligations in an amount
sufficient to pay all the principal of, and interest on, the Subordinated
Debentures on the dates such payments are due in accordance with the terms of
such Subordinated Debentures and (ii) delivers to the Subordinated Debentures
Trustee an opinion of counsel to the effect that, based upon the Company's
receipt from, or the publication by, the Internal Revenue Service of a ruling or
a change in law, the holders of the Subordinated Debentures will not recognize
income, gain or loss for United States federal income tax purposes as a result
of the deposit, defeasance and discharge and will be subject to United States
federal income tax on the same amount and in the same manner and at the same
times as would have been the case if such deposit, defeasance or discharge had
not occurred.
 
GOVERNING LAW
 
    The Debentures Indenture and the Subordinated Debentures will be governed
by, and construed in accordance with, the internal laws of the State of New
York.
 
INFORMATION CONCERNING THE SUBORDINATED DEBENTURES TRUSTEE
 
    The Subordinated Debentures Trustee, prior to default, undertakes to perform
only such duties as are specifically set forth in the Debentures Indenture and,
after default, shall exercise the same degree of care as a prudent individual
would exercise in the conduct of his or her own affairs. Subject to such
provision, the Subordinated Debentures Trustee is under no obligation to
exercise any of the powers vested in it by the Debentures Indenture at the
request of any holder of Subordinated Debentures, unless offered reasonable
indemnity by such holder against the costs, expenses and liabilities which might
be incurred thereby; but the foregoing shall not relieve the Subordinated
Debentures Trustee, upon the occurrence of an Event of Default under the
Debentures Indenture from exercising the rights and powers vested in it by the
Debentures Indenture. The Subordinated Debentures Trustee is not required to
expend or risk its own funds or otherwise incur personal financial liability in
the performance of its duties if the Subordinated Debentures Trustee reasonably
believes that repayment or adequate indemnity is not reasonably assured to it.
The Subordinated Debentures Trustee also serves as Property Trustee under the
Declaration and as the Preferred Guarantee Trustee under the Preferred
Securities Guarantee.
 
MISCELLANEOUS
 
    The Company will have the right at all times to assign any of its rights or
obligations under the Debentures Indenture to a direct or indirect wholly owned
subsidiary of the Company; PROVIDED, HOWEVER, that in the event of any such
assignment, the Company will remain liable for all of the obligations of such
subsidiary. Subject to the foregoing, the Debentures Indenture will be binding
upon and inure to the benefit of the parties thereto and their respective
successors and assigns. The Debentures Indenture provides that it may not
otherwise be assigned by the parties thereto.
 
    The Debentures Indenture will provide that the Company will pay all costs,
expenses, debts and obligations of the Trust other than with respect to the
Trust Securities.
 
                                      S-63

            EFFECT OF OBLIGATIONS UNDER THE SUBORDINATED DEBENTURES
                     AND THE PREFERRED SECURITIES GUARANTEE
 
    As set forth in the Declaration, the exclusive purposes of the Trust are to
(i) issue the Trust Securities, (ii) invest the proceeds thereof in the
Subordinated Debentures and (iii) engage in only those other activities
necessary or incidental thereto.
 
    As long as payments of interest and other payments are made when due on the
Subordinated Debentures, such payments will be sufficient to cover distributions
and payments due on the Trust Securities primarily because (i) the aggregate
principal amount of the Subordinated Debentures will be equal to the sum of the
aggregate liquidation amount of the Trust Securities; (ii) the interest rate and
interest and other payment dates on the Subordinated Debentures will match the
distribution rate and distribution and other payment dates for the Preferred
Securities; (iii) the Company shall pay for all costs, expenses, debts and
obligations of the Trust (other than with respect to the Trust Securities); and
(iv) the Declaration provides that the Company Trustees shall not cause or
permit the Trust to, among other things, engage in any activity that is not
consistent with the purposes of the Trust.
 
    Payments of distributions (to the extent funds therefor are available to the
Trust) and other payments due on the Preferred Securities (to the extent funds
therefor are available to the Trust) are guaranteed by the Company as described
under "Description of the Preferred Securities Guarantee." If the Company does
not make interest payments on the Subordinated Debentures purchased by the
Trust, it is expected that the Trust will not have sufficient funds to pay
distributions on the Preferred Securities. The Preferred Securities Guarantee
does not apply to any payment of distributions unless and until the Trust has
sufficient funds for the payment of such distributions.
 
    If the Company fails to make interest or other payments on the Subordinated
Debentures when due (taking into account any Extension Period), the Declaration
provides a mechanism whereby the holders of the Preferred Securities, using the
procedures described in "Description of the Preferred Securities-- Voting
Rights," may direct the Property Trustee to enforce its rights under the
Subordinated Debentures, including proceeding directly against the Company to
enforce the Subordinated Debentures. If the Property Trustee fails to enforce
its rights under the Debentures Indenture or the Subordinated Debentures, a
holder of Preferred Securities may, to the extent permitted by applicable law,
institute a legal proceeding directly against the Company to enforce the
Property Trustee's rights under the Debentures Indenture and the Subordinated
Debentures without first instituting any legal proceeding against the Property
Trustee or any other person or entity, including the Trust. In addition, during
the continuance of a Declaration Event of Default that results from the failure
of the Company to pay principal of or interest on the Subordinated Debentures
when due, a holder may proceed directly against the Company, without first
waiting to determine if the Property Trustee has enforced its rights under the
Declaration, to obtain payment of such principal or interest on Subordinated
Debentures having a principal amount equal to the aggregate liquidation amount
of the Preferred Securities owned of record by such holder.
 
    If the Company fails to make payments under the Preferred Securities
Guarantee, the Preferred Securities Guarantee provides a mechanism whereby the
holders of the Preferred Securities may direct the Preferred Guarantee Trustee
to enforce its rights thereunder. If the Preferred Guarantee Trustee fails to
enforce the Preferred Securities Guarantee, any holder of Preferred Securities
may institute a legal proceeding directly against the Company to enforce the
Preferred Guarantee Trustee's rights under the Preferred Securities Guarantee,
without first instituting a legal proceeding against the Trust, the Preferred
Guarantee Trustee or any other person or entity. In addition, any record holder
of Preferred Securities shall have the right, which is absolute and
unconditional, to proceed directly against the Company to obtain Guarantee
Payments, without first waiting to determine if the Preferred Guarantee Trustee
has enforced the Preferred Security Guarantee or instituting a legal proceeding
against the Trust, the Preferred Guarantee Trustee or any other person or
entity.
 
                                      S-64

    The Company's obligations under the Preferred Securities Guarantee, the
Declaration, the Subordinated Debentures and the Debentures Indenture, in the
aggregate, provide a full and unconditional guarantee by the Company of payments
due on the Preferred Securities.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a summary of certain of the principal United States federal
income tax consequences of the purchase, ownership and disposition of the
Preferred Securities. This summary is based on the Internal Revenue Code of
1986, as amended, Treasury regulations and administrative and judicial rulings
and decisions now in effect, all of which are subject to change, possibly on a
retroactive basis. This summary does not address the tax consequences applicable
to investors that may be subject to special tax rules such as banks, thrifts,
real estate investment trusts, regulated investment companies, insurance
companies, dealers in securities or currencies, tax-exempt investors or persons
that will hold the Preferred Securities as a position in a "straddle," as part
of a "synthetic security" or "hedge," as part of a "conversion transaction" or
other integrated investment or as other than a capital asset. This summary also
does not address the tax consequences to persons that have a functional currency
other than the U.S. dollar or the tax consequences to shareholders, partners or
beneficiaries of a U.S. Holder. Further, it does not include any description of
any alternative minimum tax consequences or the tax laws of any state or local
government or of any foreign government that may be applicable to a U.S. Holder.
 
    As used herein, a "U.S. Holder" means a beneficial owner of the Preferred
Securities who or that is (i) a citizen or resident of the United States, (ii) a
corporation or other entity created or organized in or under the laws of the
United States or a political subdivision thereof, (iii) an estate the income of
which is subject to U.S. federal income taxation regardless of its source, (iv)
a trust if a U.S. court is able to exercise primary supervision over the
administration of the trust and one or more U.S. persons have authority to
control all substantial decisions of the trust, or (v) otherwise subject to U.S.
federal income taxation on a net income basis in respect of the Preferred
Securities, as the case may be. As used herein, a "Non-U.S. Holder" means a
holder that is not a U.S. Holder.
 
CLASSIFICATION OF THE SUBORDINATED DEBENTURES
 
    The Company intends to take the position that the Subordinated Debentures
will be classified for United States federal income tax purposes as indebtedness
of the Company and, by acceptance of a Preferred Security, each U.S. Holder
covenants to treat the Subordinated Debentures as indebtedness and the Preferred
Securities as evidence of an indirect beneficial ownership interest in the
Subordinated Debentures. No assurance can be given however, that such position
will not be challenged by the Internal Revenue Service, or if challenged, that
such a challenge will not be successful. It has recently been reported that the
Internal Revenue Service challenged the status as indebtedness, for U.S. federal
income tax purposes, of certain instruments analogous to the Subordinated
Debentures, held by an entity similar in certain respects to the Trust. See
"Description of the Preferred Securities--Special Event Redemption or
Distribution." Based on the information available to it, the Company does not
believe that the treatment of the Subordinated Debentures as indebtedness for
federal income tax purposes is jeopardized by the position reported to have been
taken. The remainder of this discussion assumes that the Subordinated Debentures
will be classified as indebtedness of the Company for United States federal
income tax purposes.
 
CLASSIFICATION OF CIRCUS FINANCE I
 
    Wolf, Block, Schorr and Solis-Cohen LLP, special tax counsel to the Company
and the Trust, is of the opinion that, under current law and assuming full
compliance with the terms of the Debentures Indenture and the Declaration (and
certain other documents), the Trust will be classified as a "grantor trust" for
United States federal income tax purposes and will not be classified as an
association taxable as a corporation or a partnership. Each U.S. Holder will be
treated as owning an undivided beneficial interest
 
                                      S-65

in the Subordinated Debentures. Accordingly, each U.S. Holder will be required
to include in its gross income the interest and/or original issue discount
("OID") paid or accrued with respect to its allocable share of Subordinated
Debentures. Investors should be aware that the opinion of Wolf, Block, Schorr
and Solis-Cohen LLP does not address any other issue and is not binding on the
Internal Revenue Service or the courts.
 
INTEREST, ORIGINAL ISSUE DISCOUNT, PREMIUM AND MARKET DISCOUNT
 
    Under applicable Treasury regulations (the "Regulations"), if the likelihood
that the stated interest on a debt instrument will not be paid timely is
"remote," such likelihood is ignored in determining whether the debt instrument
is issued with OID. The Company does not intend to treat the likelihood of
exercising its option to defer payments of interest on the Subordinated
Debentures as remote within the meaning of the Regulations. Consequently, the
Company intends to take the position that the Subordinated Debentures will be
considered to be issued with OID at the time of their original issuance and that
a U.S. Holder of Preferred Securities should include in gross income such
holder's allocable share of the interest paid on the Subordinated Debentures as
OID. In such event, U.S. Holders would include the OID attributable to the
Subordinated Debentures in income on a daily economic accrual basis before the
receipt of cash attributable to the interest, regardless of their method of tax
accounting. The amount of OID that accrues in any month will approximately equal
the amount of the interest that accrues in that month at the stated interest
rate. In the event that the interest payment period is extended, Holders will
continue to accrue OID approximately equal to the amount of the interest payment
due at the end of the extended interest payment period on an economic accrual
basis over the length of the extended interest payment period. Corporate U.S.
Holders will not be entitled to a dividends-received deduction with respect to
any income earned with respect to the Preferred Securities.
 
    No rulings or interpretations have been issued by the Internal Revenue
Service which address the meaning of the term "remote" as used in the
Regulations, and it is possible that the Internal Revenue Service could take a
position contrary to that expressed herein.
 
    To the extent a U.S. Holder acquires its Preferred Securities at a price
that is greater or less than the principal amount of such U.S. Holder's share of
the Subordinated Debentures, the U.S. Holder will be deemed to have acquired its
interest in the Preferred Securities with amortizable bond premium or with
market discount, as the case may be. A U.S. Holder acquiring Preferred
Securities at a premium will be permitted to reduce the amount of OID required
to be included in income to reflect such acquisition premium. A U.S. Holder
acquiring Preferred Securities at a market discount will also include the amount
of such discount in income in accordance with the market discount rules
described below.
 
    A U.S. Holder acquiring Preferred Securities at a market discount generally
will be required to recognize ordinary income to the extent of accrued market
discount upon the retirement of the underlying Subordinated Debentures or, to
the extent of any gain, upon the disposition of the Preferred Securities. Such
market discount would accrue on a straight-line basis, or, at the election of
the U.S. Holder, under a constant yield method over the remaining term of the
Subordinated Debentures. A U.S. Holder may also be required to defer the
deduction of a portion of the interest paid or accrued on indebtedness incurred
to purchase or carry Preferred Securities acquired with market discount. In lieu
of the foregoing, a U.S. Holder may elect to include market discount in income
currently as it accrues on all market discount instruments acquired by such
holder in the taxable year of the election or thereafter, in which case the
interest deferral rule will not apply. A U.S. Holder may elect, in lieu of
applying the market discount or premium rules described above, to account for
all income under the Preferred Securities as if it were OID.
 
RECEIPT OF SUBORDINATED DEBENTURES OR CASH UPON LIQUIDATION OF THE TRUST
 
    Under certain circumstances, as described under the caption "Description of
the Preferred Securities--Special Event Redemption or Distribution,"
Subordinated Debentures may be distributed to Holders
 
                                      S-66

in exchange for the Preferred Securities and in liquidation of the Trust. Such a
distribution would be treated as a non-taxable event to each U.S. Holder and
each U.S. Holder would receive an aggregate tax basis in the Subordinated
Debentures equal to such Holder's aggregate tax basis in the Preferred
Securities. A U.S. Holder's holding period in the Subordinated Debentures so
received in liquidation of the Trust would include the period for which the
Preferred Securities were held by such holder. If, however, the Trust is
characterized for United States federal income tax purposes as an association
taxable as a corporation at the time of its dissolution, the distribution of the
Subordinated Debentures would constitute a taxable event to U.S. Holders of
Preferred Securities and a U.S. Holder's holding period in Subordinated
Debentures would not include the period during which the Subordinated Debentures
were held by the Trust.
 
    Under certain circumstances described herein (see "Description of the
Preferred Securities"), the Subordinated Debentures may be redeemed for cash and
the proceeds of such redemption distributed to holders in redemption of their
Preferred Securities. Such a redemption would, for United States federal income
tax purposes, constitute a taxable disposition of the redeemed Preferred
Securities, and a U.S. Holder would recognize gain or loss as if it sold such
redeemed Preferred Securities for cash. See "--Sale of Preferred Securities."
 
SALE OF PREFERRED SECURITIES
 
    A U.S. Holder that sells Preferred Securities will recognize gain or loss
equal to the difference between its adjusted tax basis in the Preferred
Securities and the amount realized on the sale. A U.S. Holder's adjusted tax
basis in the Preferred Securities generally will be such holder's initial
purchase price increased by OID previously included in such holder's gross
income to the date of disposition and decreased by payments received on the
Preferred Securities. Subject to the market discount rules described above, any
such gain or loss generally will be capital gain or loss and generally will be
long-term capital gain or loss if the Preferred Securities have been held for
more than one year.
 
    The Preferred Securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest with respect to the underlying
Subordinated Debentures. A U.S. Holder disposing of its Preferred Securities
between record dates for payments of distributions thereon will be required to
include accrued but unpaid interest through the date of disposition in income
(to the extent not previously included in income) as ordinary income, and the
amount realized on disposition excludes the portion of the sale price treated as
interest. To the extent the amount realized on disposition is less than the U.S.
Holder's adjusted tax basis, a U.S. Holder will recognize a capital loss.
Subject to certain limited exceptions, capital losses cannot be applied to
offset ordinary income for United States federal income tax purposes.
 
NON-U.S. HOLDERS
 
    Subject to the discussion of backup withholding below, interest (including
OID, if any) with respect to the Preferred Securities paid to a Non-U.S. Holder
will be exempt from U.S. withholding tax, provided that the Holder complies with
applicable certification requirements (and does not actually or constructively
own ten percent or more of the voting stock of the Company and is not a
controlled foreign corporation related to the Company or its affiliates).
 
INFORMATION REPORTING TO HOLDERS
 
    Subject to the qualifications discussed below, income on the Preferred
Securities generally will be reported to Holders on Form 1099, which forms
should be mailed to holders of Preferred Securities by January 31 following each
calendar year.
 
                                      S-67

BACKUP WITHHOLDING
 
    Payments made on, and proceeds from the sale of, the Preferred Securities
may be subject to a "backup" withholding tax of 31% unless the holder complies
with certain identification requirements. Any withheld amounts will be allowed
as a credit against the holder's United States federal income tax, provided that
required information is provided to the Internal Revenue Service. Recently
promulgated Treasury regulations, effective for certain payments made to
Non-U.S. Holders after December 31, 1999, may change certain certification
procedures relating to the receipt by intermediaries of payments on behalf of a
beneficial owner of Preferred Securities. Prospective investors should consult
their tax advisors regarding the possible effect of such new Treasury
regulations on an investment in the Preferred Securities.
 
    THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S PARTICULAR
SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE PREFERRED
SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER
TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.

                                  UNDERWRITING
 
    Subject to the terms and conditions set forth in a purchase agreement (the
"Purchase Agreement"), the Trust has agreed to sell to each of the underwriters
named below (the "Underwriters"), and each of the Underwriters, for whom
                    is acting as representative (the "Representative"), has
severally agreed to purchase, the number of Preferred Securities set forth
opposite its name below.
 


                                                                                                    NUMBER OF

    Total.....................................................................................
                                                                                                ------------------
                                                                                                ------------------

 
    In the Purchase Agreement, the several Underwriters have agreed, subject to
the terms and conditions set forth therein, to purchase all of the Preferred
Securities offered hereby if any of the Preferred Securities are purchased. In
the event of default by an Underwriter, the Purchase Agreement provides that, in
certain circumstances, the purchase commitments of the nondefaulting
Underwriters may be increased or the Purchase Agreement may be terminated.
 
    The Underwriters propose initially to offer the Preferred Securities to the
public at the initial public offering price set forth on the cover page   of
this Prospectus Supplement, and to certain dealers at such price less a
concession not in excess of $     per Preferred Security; PROVIDED, HOWEVER,
that such concession for sales of 10,000 or more Preferred Securities to a
single purchaser will not be in excess of $     per Preferred Security. The
Underwriters may allow, and such dealers may reallow, a discount not in excess
of $     per Preferred Security to certain other dealers. After the initial
public offering, the public offering price, concession and discount may be
changed.
 
                                      S-69

    In view of the fact that the proceeds of the sale of the Preferred
Securities will be used to purchase the Subordinated Debentures of the Company,
the Purchase Agreement provides that the Company will pay as compensation
("Underwriters' Compensation") to the Underwriters for the Underwriters
arranging the investment therein of such proceeds, an amount in same-day funds
of $     per Preferred Security (or $     in the aggregate); PROVIDED, HOWEVER,
that such compensation for sales of 10,000 or more Preferred Securities to any
single purchaser will be $     per Preferred Security. Therefore, to the extent
of such sales, the actual amount of Underwriters' Compensation will be less than
the aggregate amount specified in the preceding sentence.
 
    During a period of 30 days from the date of this Prospectus Supplement,
neither the Trust nor the Company will, without the prior written consent of the
Representative, directly or indirectly, sell, offer to sell, contract to sell,
grant any option for the sale of, or otherwise dispose of, any Preferred
Securities, any security convertible into, or exchangeable or exercisable for,
Preferred Securities or any debt securities substantially similar to the
Subordinated Debentures or any equity securities substantially similar to the
Preferred Securities (except for the Subordinated Debentures and the Preferred
Securities offered hereby and subject to certain exceptions specified in the
Purchase Agreement).
 
    Prior to this Offering there has been no public market for the Preferred
Securities. The Representative has advised the Trust that the Underwriters
intend to make a market in the Preferred Securities but will have no obligation
to make a market in the Preferred Securities and may cease market making
activities, if commenced, at any time. In order to meet one of the requirements
for listing the Preferred Securities on the New York Stock Exchange, the
Underwriters will undertake to sell lots of 100 or more Preferred Securities to
a minimum of 400 beneficial holders.
 
    The Company and the Trust have agreed to indemnify the Underwriters against,
or to contribute to payments that the Underwriters may be required to make in
respect of, certain liabilities, including liabilities under the Securities Act
of 1933, as amended.
 
    Certain of the Underwriters engage in transactions with, and from time to
time have performed services for, the Company in the ordinary course of
business.
 
    Until the distribution of the Preferred Securities is completed, rules of
the Securities and Exchange Commission may limit the ability of the Underwriters
and certain selling group members to bid for and purchase the Preferred
Securities. As an exception to these rules, the Representative is permitted to
engage in certain transactions that stabilize the price of the Preferred
Securities. Such transactions consist of bids or purchases for the purpose of
pegging, fixing or maintaining the price of the Preferred Securities.
 
    If the Underwriters create a short position in the Preferred Securities in
connection with this offering, I.E., if they sell more Preferred Securities than
are contemplated on the cover page of this Prospectus Supplement, the
Representative may reduce that short position by purchasing Preferred Securities
in the open market.
 
    The Representative may also impose a penalty bid on certain Underwriters and
selling group members. This means that if the Representative purchases Preferred
Securities in the open market to reduce the Underwriters' short position or to
stabilize the price of the Preferred Securities they may reclaim the amount of
the selling concession from the Underwriters and selling group members who sold
those securities as part of the offering.
 
    In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it were
to discourage resales of the security.
 
    Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above might have on the price of the
 
                                      S-70

Preferred Securities. In addition, neither the Company nor any of the
Underwriters makes any representation that the Representative will engage in
such transactions or that such transactions, once commenced, will not be
discontinued without notice.
 
                                 LEGAL MATTERS
 
    Certain matters of Delaware law relating to the validity of the Preferred
Securities, the validity of the Subordinated Debentures, the Preferred
Securities Guarantee and certain matters relating thereto, and certain United
States federal income taxation matters will be passed upon by Wolf, Block,
Schorr and Solis-Cohen LLP, Philadelphia, Pennsylvania, counsel to the Company
and the Trust. Certain matters of
Nevada law will be passed upon for the Company and the Trust by Schreck Morris,
Las Vegas, Nevada. Certain legal matters will be passed upon on behalf of the
Underwriters, by                      .

    Circus Circus Enterprises, Inc., a Nevada corporation (the "Company"), may
offer from time to time in one or more series its debt securities consisting of
debentures, notes or other evidence of indebtedness (the "Debt Securities") on
terms to be determined at the time of the offering. At the option of the
Company, the Debt Securities may be issued as senior secured Debt Securities, as
senior unsecured Debt Securities, as senior subordinated Debt Securities or as
subordinated Debt Securities and in any combination thereof. The general terms
and conditions of the Debt Securities are described under "Description of Debt
Securities" in this Prospectus. The Company may also from time to time issue its
unsecured subordinated deferrable interest debentures (the "Subordinated
Deferrable Interest Debentures") and Trust Preferred Securities Guarantees (as
defined), as described herein and in the applicable Prospectus Supplement.
 
    Circus Finance I and Circus Finance II (each a "Trust"), each a statutory
business trust formed under the laws of Delaware, may from time to time offer
preferred securities evidencing preferred beneficial interests in the assets of
the respective Trust ("Trust Preferred Securities"). The payment of periodic
cash distributions ("distributions") with respect to Trust Preferred Securities
of each of the Trusts, out of moneys held by each of the Trusts, and payments on
liquidation, redemption or otherwise with respect to such Trust Preferred
Securities will be guaranteed by the Company as described herein (each, a "Trust
Preferred Securities Guarantee"). The Company's obligations under the Trust
Preferred Securities Guarantees will be subordinate and junior in right of
payment to all other liabilities of the Company and PARI PASSU (equally and
ratably) with the most senior preferred stock issued by the Company and with any
guarantee that may be entered into by the Company in respect of any preferred
stock of any subsidiary or affiliate of the Company. Subordinated Deferrable
Interest Debentures may be issued and sold from time to time in one or more
series by the Company to a Trust in connection with the investment of the
proceeds from the offering of Trust Preferred Securities and Trust Common
Securities (as defined herein) of such Trust. The Subordinated Deferrable
Interest Debentures subsequently may be distributed pro rata to holders of Trust
Preferred Securities and Trust Common Securities in connection with the
termination of such Trust upon the occurrence of certain events as may be
described in the Prospectus Supplement. The Debt Securities, the Trust Preferred
Securities, the Trust Preferred Securities Guarantees and the Subordinated
Deferrable Interest Debentures are collectively referred to as the "Securities."

    The Trust Preferred Securities (which will be issued with a Trust Preferred
Securities Guarantee, and the proceeds of which will be used exclusively to
purchase Subordinated Deferrable Interest Debentures) and the Debt Securities
offered pursuant to this Prospectus may be offered separately or together in one
or more series up to an aggregate public offering price of $550,000,000 (or the
equivalent thereof in foreign currency or currency units), in each case at
individual prices and on terms to be determined at the time of the offering and
set forth in one or more supplements to this Prospectus (each, a "Prospectus
Supplement").
 
    The specific terms of the Securities in respect of which this Prospectus is
being delivered will be set forth in the applicable Prospectus Supplement and,
among other things, will include, where applicable, (i) in the case of Debt
Securities or Subordinated Deferrable Interest Debentures, the specific
designation, aggregate principal amount offered, ranking, rate or rates of
interest or the provisions for determining such rate or rates (which may be
fixed or variable) or the manner of calculation thereof, if any, the time of
payment of interest, if any, maturity (which may be fixed or extendible), form
(which may be certificated or global), authorized denominations, currency of
payment, any terms relating to redemption (whether mandatory, at the option of
the Company or the holder), terms for sinking fund payments, additional
covenants, the initial public offering price, the purchase price and other terms
with respect to such Securities and (ii) in the case of shares of Trust
Preferred Securities, the number of shares, specific title and stated value, any
dividend, liquidation, redemption, voting and other rights and restrictions and
the initial public offering price.
 
    The applicable Prospectus Supplement will also contain information, where
applicable, about certain U.S. Federal income taxes, accounting and other

applicable Trust from time to time. If any agents of the Company or the
applicable Trust or any dealers or underwriters are involved in the sale of the
Securities in respect of which this Prospectus is being delivered, the name of
such agents, dealers or underwriters and any applicable agent's commission,
dealer's purchase price or underwriter's discount will be as set forth in or may

                             AVAILABLE INFORMATION
 
    The Company and the Trusts have filed with the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Securities Act"), a combined registration statement on Form S-3 (herein,
together with all amendments thereto and exhibits filed therewith, referred to
as the "Registration Statement") relating to the Debt Securities, the
Subordinated Deferrable Interest Debentures, the Trust Preferred Securities and
the Trust Preferred Securities Guarantees.
 
    The Company is subject to the informational requirements of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and, in accordance
therewith, files reports, proxy statements, information statements and other
information with the Commission. Such reports, proxy statements, information
statements and other information concerning the Company can be inspected and
copied at the public reference facilities maintained by the Commission at 450
Fifth Street, N.W., Room 1024, Washington D.C. 20549, and at the Commission's
Regional Offices at Seven World Trade Center, 13th Floor, New York, New York
10048, and Citicorp Center, 500 West Madison Street, Suite 1400, Chicago,
Illinois 60661. Copies of such material can be obtained from the Public
Reference Room of the Commission at 450 Fifth Street, N.W., Room 1024,
Washington, D.C. 20549, upon the payment of fees prescribed by the Commission.
The Commission maintains a site on the World Wide Web that contains reports,
proxy and information statements and other information regarding registrants
(including the Company) that file electronically with the Commission. The
address of the Commission's Web site is http://www.sec.gov. Reports, proxy
statements, information statements and other information concerning the Company
can also be inspected at the offices of the New York Stock Exchange, Inc.
located at 20 Broad Street, New York, New York 10005 and at the Pacific
Exchange, 301 Pine Street, San Francisco, California 94104.
 
    This Prospectus does not contain all the information set forth in the
Registration Statement of which this Prospectus is a part filed by the Company
and the Trusts with the Commission under the Securities Act. Statements
contained herein concerning the provisions of any contract or other document are
necessarily summaries of such contracts or documents, and each statement is
qualified in its entirety by reference to the copy of the applicable contract or
document filed with the Commission. A copy of the Registration Statement is on
file at the offices of the Commission and may be obtained upon payment of fees
prescribed by the Commission, or may be examined without charge at the public
reference facilities of the Commission described above or at the Commission's
Web site, the address of which is set forth above.
 
    No separate financial statements of the Trusts have been included herein.
The Company does not believe that such financial statements would be material to
holders of the Trust Preferred Securities because (i) all of the voting
securities of the Trusts will be owned, directly or indirectly, by the Company,
a reporting company under the Exchange Act, (ii) the Trusts have no independent
operations and exist for the sole purpose of issuing securities representing
undivided beneficial interests in the assets of the applicable Trust and
investing the proceeds thereof in the Subordinated Deferrable Interest
Debentures issued by the Company and (iii) the obligations of each Trust under
the Trust Securities are fully and unconditionally guaranteed by the Company to
the extent that such Trust has funds available to meet such obligations. See
"The Trusts," "Description of the Trust Preferred Securities," "Description of
the Trust Preferred Securities Guarantees" and "Description of the Subordinated
Deferrable Interest Debentures." The Trusts do not expect to file separate
reports under the Exchange Act but must apply for and be granted relief by the
Commission to avoid the requirement to file such reports.

                                       4

                                  THE COMPANY
 
    Circus Circus Enterprises, Inc., which was incorporated in 1974, currently
owns and operates, through wholly owned subsidiaries, nine hotel-casino
properties in Nevada with a total of approximately 17,700 guest rooms. These
properties include (i) three hotel/casinos in Las Vegas (Circus Circus-Las
Vegas, Luxor and Excalibur), (ii) Circus Circus Hotel and Casino in Reno, (iii)
Colorado Belle Hotel and Casino and Edgewater Hotel and Casino which are located
on the Colorado River in Laughlin, (iv) Gold Strike Hotel and Gambling Hall and
Nevada Landing Hotel & Casino in Jean, and (v) Railroad Pass Hotel and Casino in
Henderson. The Company also owns and operates a dockside casino situated on a
24-acre site in Tunica County, Mississippi, which includes a 1,066-room hotel
tower placed in service during late 1997 and early 1998. It also operates two
smaller casinos on the Las Vegas Strip, Slots-A-Fun (which the Company also
owns) and Silver City Casino (which the Company operates under a lease which
expires in October 1999).
 
    In the Spring of 1997, the Company commenced construction of Mandalay Bay
(formerly referred to as Project Paradise), a 43-story, hotel-casino resort
which will have approximately 3,700 rooms and approximately 135,000 square feet
of gaming space. The resort, which is expected to be completed in the first
quarter of 1999, will be situated on approximately 60 acres of land just south
of Luxor. Mandalay Bay's attractions are planned to include an 11-acre tropical
lagoon featuring a sand-and-surf beach, a three-quarter-mile lazy river ride, a
30,000-square-foot spa and other entertainment attractions. Inside, Mandalay Bay
will offer internationally renowned restaurants, as well as a House of Blues
nightclub and restaurant, including its signature Foundation Room sited on
Mandalay Bay's rooftop, and 100 "music-themed" hotel rooms in Mandalay Bay's
towers.
 
    Within Mandalay Bay and as part of its 3,700 rooms, a Four Seasons Hotel
with approximately 400 rooms will provide Las Vegas visitors with a luxury
"five-star" hospitality experience. The Four Seasons Hotel, which will be owned
by the Company and managed by Four Seasons Hotels Limited ("Four Seasons"),
represents the first step pursuant to the Company's cooperative effort with Four
Seasons to identify strategic opportunities for development of hotel and casino
properties worldwide. The cost of Mandalay Bay, including the Four Seasons Hotel
but excluding the land, is currently estimated at approximately $850 million.
 
    During the course of construction, Mandalay Bay's hotel tower has
experienced settling which has exceeded the level contemplated in the building's
original design and the amount of settling has been greater in some portions of
the structure than others. The Company has retained geotechnical, structural
engineering and foundation consultants who are evaluating the situation and have
recommended remedial measures which are in the initial stages of implementation.
Completion of the recommended remedial measures is not expected to delay the
opening of Mandalay Bay or materially increase the cost of the project. However,
until such remedial measures are completed and evaluated and the ongoing
evaluation of the site is concluded there can be no assurances that further
corrective measures will not be required or, if additional measures are
required, as to the cost of such measures or their impact, if any, on the
scheduled completion and opening of Mandalay Bay.
 
    Mandalay Bay is the latest phase of the Company's development of over 230
acres of land it owns at the south end of the Las Vegas Strip which runs from
Tropicana Avenue south approximately one mile to Russell Road ("Masterplan
Mile"). As part of its development plan for Masterplan Mile, the Company is
constructing a 125,000-square-foot convention facility and a 12,000-seat arena.
These facilities are expected to be completed and opened concurrently with
Mandalay Bay, and will represent core components of Masterplan Mile which will
be cross-marketed to guests at the Company's existing and future hotel-casinos
within Masterplan Mile. The estimated cost of the convention facility and arena
is approximately $100 million.
 
    The Company also plans to construct a monorail system which will link the
Company's resorts on Masterplan Mile. Furthermore, the Company is planning a
"Sea of Predators" aquarium exhibit which will likewise represent a core
component of Masterplan Mile. Both the monorail and the Sea of Predators
 
                                       5

exhibit are anticipated to be completed after the opening of Mandalay Bay. The
cost of these additional Masterplan Mile core components is estimated at
approximately $75 million. The Company may add other core components to its
development plan for Masterplan Mile in the future.
 
    The Company, through wholly owned subsidiaries, is a 50% participant in
three joint ventures which own and operate gaming properties. They include (i) a
joint venture which owns and operates Monte Carlo, a 3,002-room hotel/casino on
the Las Vegas Strip that opened in June 1996, (ii) a joint venture which owns
and operates the Grand Victoria, a riverboat casino and related land-based
entertainment complex located in Elgin, Illinois, and (iii) a joint venture
which owns and operates Silver Legacy, a 1,711-room hotel/casino located in
downtown Reno that opened in July 1995 and is situated between (and connected by
enclosed climate-controlled skyways to) Circus Circus-Reno and another
hotel/casino owned and operated by an affiliate of the other joint venture
participant.
 
    The Company is also a participant in another joint venture which has been
selected to develop one of three casinos permitted to be developed in Detroit,
Michigan. The Company will own a 45% equity interest in the proposed project and
receive a management fee. A development agreement between this joint venture and
the City of Detroit was approved by the Detroit City Council on April 9, 1998.
The joint venture's ability to proceed with the proposed project is contingent
upon the receipt of all necessary gaming approvals and satisfaction of other
conditions. The joint venture is planning a $600 million project, of which the
Company would be required to contribute 20% of such amount in the form of
equity, with the balance being provided through project-specific financing.
 
    The Company's executive offices are located at 2880 Las Vegas Boulevard
South, Las Vegas, Nevada 89109, and its telephone number is (702) 734-0410.
Unless the context otherwise indicates, all references herein to the Company are
to Circus Circus Enterprises, Inc. and its subsidiaries.
 
                                   THE TRUSTS
 
    Each of Circus Finance I and Circus Finance II is a statutory business trust
formed under the Delaware Business Trust Act, as amended (the "Trust Act")
pursuant to (i) a separate declaration of trust, executed by the Company, as
sponsor for such trust (the "Sponsor"), and the Trustees (as defined herein) of
such trust as of that date and (ii) the filing of a separate certificate of
trust with the Delaware Secretary of State. The declaration of trust of each
Trust will be amended and restated in its entirety (as so amended and restated,
the "Declaration") substantially in the form filed as an exhibit to the
Registration Statement filed by the Company and the Trusts of which this
Prospectus forms a part. Each Trust exists for the exclusive purposes of (i)
issuing and selling the Trust Preferred Securities representing preferred
undivided beneficial interests in the assets of such Trust and Trust Common
Securities representing common undivided beneficial interests in the assets of
such Trust (the "Trust Common Securities" and, together with the Trust Preferred
Securities, the "Trust Securities"), (ii) investing the gross proceeds of the
Trust Securities in a series of Subordinated Deferrable Interest Debentures and
(iii) engaging in only those other activities necessary or incidental thereto.
All of the Trust Common Securities will be directly or indirectly owned by the
Company. The Trust Common Securities will rank PARI PASSU, and payments will be
made thereon pro rata, with the Trust Preferred Securities except that upon the
occurrence and during the continuation of an Event of Default (as defined in the
Declaration), the rights of the holders of the Trust Common Securities to
payment in respect of distributions and payments upon liquidation, redemption
and otherwise will be subordinated to the rights of the holders of the Trust
Preferred Securities. The Company will, directly or indirectly, acquire Trust
Common Securities in an aggregate liquidation amount equal to 3% of the total
capital of each Trust. Each Trust has a term of approximately 55 years, but may
earlier terminate as provided in the applicable Declaration. Each Trust's
business and affairs will be conducted by the trustees (the "Trustees")
appointed by the Company, as the direct or indirect holder of all the Trust
Common Securities. The holder of the Trust Common Securities will be entitled to
appoint, remove or replace any of, or increase or reduce the number of, the
Trustees of a Trust. The duties and obligations of such Trustees shall be
governed by the Declaration of such Trust, the Trust Indenture Act of 1939, as
 
                                       6

amended (the "Trust Indenture Act"), and the Trust Act. A majority of the
Trustees (the "Regular Trustees") of each Trust will be persons who are
employees or officers of or affiliated with the Company. One Trustee of each
Trust will be a financial institution which will be unaffiliated with the
Company and which shall act as property trustee and as indenture trustee for
purposes of the Trust Indenture Act pursuant to the terms set forth in a
Prospectus Supplement (the "Property Trustee"). In addition, unless the Property
Trustee maintains a principal place of business in the State of Delaware, and
otherwise meets the requirements of applicable law, another Trustee of each
Trust will have its principal place of business or reside in the State of
Delaware (the "Delaware Trustee"). The Company will pay all fees, expenses,
debts and obligations (other than the Trust Securities) related to the Trusts
and the offering of Trust Securities. The office of the Delaware Trustee for
each Trust in the State of Delaware is The Bank of New York (Delaware), 400
White Clay Center, Route 273, Newark, Delaware 19711. The principal place of
business of each Trust shall be c/o Circus Circus Enterprises, Inc., 2880 Las
Vegas Boulevard South, Las Vegas, Nevada 89109 (telephone number 702-734-0410).
 
                               GAMING REGULATION
 
    The ownership and operation of casino gaming facilities are subject to
extensive state and local regulation. In the States of Illinois, Mississippi and
Nevada licensed gaming operations are currently conducted by the Company through
wholly owned subsidiaries and/or by joint ventures in which entities wholly
owned by the Company are participants. A joint venture in which a wholly owned
subsidiary of the Company is a participant plans (subject to receipt of the
requisite approvals and licenses) to conduct licensed gaming operations in the
future in Detroit, Michigan. The Company and a wholly owned subsidiary of the
Company have also filed gaming applications in New Jersey in connection with
plans to acquire land in Atlantic City, construct a hotel-casino and conduct
gaming operations, subject to the successful resolution of currently pending
litigation, the receipt of applicable regulatory approvals and the satisfaction
of other conditions. Each of these states, as well as the applicable local
authorities in such states, requires various licenses, findings of suitability,
registrations, permits and approvals (individually, a "Gaming License" and
collectively, "Gaming Licenses") to be held by the Company and its subsidiaries
and joint ventures that are engaged in gaming operations. The Illinois Gaming
Board, the Michigan Gaming Control Board, the Mississippi Gaming Commission, the
Nevada Gaming Commission, the New Jersey Casino Control Commission and any other
governmental authority which now or hereafter has regulatory authority over any
gaming operations conducted or proposed to be conducted by the Company, any of
its subsidiaries or any joint ventures in which the Company or any entity
wholly-owned by the Company is a participant (individually, a "Gaming Authority"
and collectively, the "Gaming Authorities") may, among other things, deny,
limit, condition, suspend or revoke a Gaming License or approval to own the
stock or joint venture interest of any of the licensed operations conducted in
such states by the Company or its subsidiaries or joint ventures for any cause
deemed reasonable by such licensing authority. Substantial fines or forfeiture
of assets for violations of gaming laws or regulations may be levied against the
Company, such subsidiaries and joint ventures and the individuals involved. The
denial, suspension or revocation of any Gaming License of the Company or any of
its subsidiaries or joint ventures or the levy on the Company or any of such
subsidiaries or joint ventures of substantial fines or forfeiture of assets
could have a material adverse effect on the business of the Company.
 
    To date, the Company has obtained all Gaming Licenses necessary for the
operation of its existing gaming activities. However, Gaming Licenses and
related approvals are deemed to be privileges under Illinois, Mississippi and
Nevada as well as Michigan and New Jersey law, and no assurance can be given
that any new Gaming License that may be required in the future will be granted
or that existing Gaming Licenses will not be revoked or suspended.
 
    The Nevada Gaming Commission (the "Nevada Commission") may, in its
discretion, require the holder of any securities issued by the Company to file
applications, be investigated and be found suitable to own such securities if it
has reason to believe that such ownership would be inconsistent with the
declared
 
                                       7

policies of the State of Nevada. If the Nevada Commission determines that a
person is unsuitable to own such securities, then pursuant to the Nevada Gaming
Control Act and the regulations promulgated thereunder, the Company can be
sanctioned, including the loss of its approvals, if without the prior approval
of the Nevada Commission, it: (i) pays to the unsuitable person any dividend,
interest or any distribution whatsoever; (ii) recognizes any voting right by
such unsuitable person in connection with such securities; (iii) pays the
unsuitable person remuneration in any form; or (iv) makes any payment to the
unsuitable person by way of principal, redemption, conversion, exchange,
liquidation or similar transaction.
 
    The Illinois Gaming Board and the Mississippi Gaming Commission have
jurisdiction over the holders and beneficial owners of securities issued by the
Company similar to that of the Nevada Commission and may also require their
investigation and approval, the Michigan Gaming Control Board will have such
jurisdiction and authority if a joint venture which includes among its
participants a wholly owned subsidiary of the Company is subsequently licensed
to conduct gaming operations in Detroit, Michigan, and the New Jersey Casino
Control Commission will have such jurisdiction and authority if the Company and
a subsidiary of the Company are subsequently licensed to conduct gaming
operations in New Jersey. An applicant must pay all costs of investigation
incurred by a Gaming Authority in conducting an investigation relating to such
applicant.
 
    In certain jurisdictions, including Mississippi and Nevada, the Company may
not make a public offering of its securities without prior approval of the
applicable Gaming Authorities if the securities or proceeds therefrom are
intended to be used to construct, acquire or finance gaming facilities in such
jurisdictions, or to retire or extend obligations incurred for such purposes or
for similar transactions. On May 22, 1997, the Nevada Commission granted the
Company prior approval to make public offerings of its securities for a period
of two years, subject to certain conditions (the "Nevada Shelf Approval"). The
Nevada Shelf Approval also applies to any affiliated company wholly owned by the
Company (a "Gaming Affiliate") which is a publicly traded corporation or would
become a publicly traded corporation pursuant to a public offering. The Nevada
Shelf Approval also includes approval for the Company's registered and licensed
subsidiaries to guarantee any security issued by, and to hypothecate their
assets to secure the payment or performance of any obligation issued by, the
Company or a Gaming Affiliate in a public offering under the Nevada Shelf
Approval. However, the Nevada Shelf Approval may be rescinded for good cause
without prior notice upon the issuance of an interlocutory stop order by the
Chairman of the Nevada State Gaming Control Board (the "Nevada Board") and must
be renewed biennially. The Nevada Shelf Approval does not constitute a finding,
recommendation or approval by the Nevada Commission or the Nevada Board as to
the accuracy or adequacy of this Prospectus or any related Prospectus Supplement
or the investment merits of the Securities offered. Any representation to the
contrary is unlawful. The Company received a similar one-year waiver of approval
requirements from the Mississippi Gaming Commission on January 22, 1998 (the
"Mississippi Shelf Approval"). The public offering of the Debt Securities,
Subordinated Deferred Interest Debentures and the Trust Preferred Securities
Guarantees will be made pursuant to the Nevada Shelf Approval and the
Mississippi Shelf Approval, each as currently in effect or as may be renewed in
the discretion of the applicable Gaming Authority. The public offering of the
Trust Securities does not require any additional prior approval.
 
    For information concerning the requirement that Debt Securities, Trust
Preferred Securities or Subordinated Deferrable Interest Debentures be disposed
of by holders or beneficial owners under certain circumstances, see "Description
of Debt Securities--Mandatory Disposition Pursuant to Gaming Laws," "Description
of the Trust Preferred Securities" and "Description of the Subordinated
Deferrable Interest Debentures--Mandatory Disposition Pursuant to Gaming Laws."
 
    The foregoing is only a summary of the regulatory requirements applicable to
the Company and the holders of its securities. For additional information
regarding the gaming laws and regulations applicable to the Company's gaming
operations and the holders of its securities, see the discussion under the
caption "Regulation and Licensing" in Item I of the Company's Annual Report on
Form 10-K for the fiscal year ended January 31, 1998, incorporated by reference

                                USE OF PROCEEDS
 
    The Company intends to use the net proceeds from the sale of the Securities
for general corporate purposes, which may include financing the development and
construction of new facilities, other capital expenditures, working capital, the
repayment or repurchase of outstanding indebtedness, share repurchases or such
other purposes as may be specified in an accompanying Prospectus Supplement.
 
               ACCOUNTING TREATMENT RELATING TO TRUST SECURITIES
 
    The financial statements of each Trust that has issued Trust Securities will
be consolidated with the Company's financial statements, with the Trust
Preferred Securities of each Trust shown on the Company's consolidated financial
statements as Company-obligated mandatorily redeemable preferred securities of
subsidiary trusts holding solely subordinated debt securities of the Company.
The Company's financial statements will include a footnote that discloses, among
other things, that the sole asset of each Trust included therein consists of
Subordinated Deferrable Interest Debentures of the Company, and will specify the
designation, principal amount, interest rate and maturity date of such
Subordinated Deferrable Interest Debentures.
 
                         DESCRIPTION OF DEBT SECURITIES
 
    The following description of the terms of the Debt Securities sets forth
certain general terms and provisions of the Debt Securities to which any
Prospectus Supplement may relate. The particular terms of the Debt Securities
offered by any Prospectus Supplement and the extent to which such general
provisions may apply to the Debt Securities will be described in a Prospectus
Supplement relating to such Debt Securities.
 
    The Debt Securities may constitute either senior secured debt ("Senior
Secured Debt Securities"), senior unsecured debt ("Senior Unsecured Debt
Securities"), senior subordinated debt ("Senior Subordinated Debt Securities")
or subordinated debt ("Subordinated Debt Securities" and, collectively with the
Senior Subordinated Debt Securities, the "Subordinated Securities"), or any
combination thereof, of the Company. Each such series of Debt Securities will be
issued under a separate indenture (the "Senior Secured Debt Indenture," the
"Senior Unsecured Debt Indenture," the "Senior Subordinated Debt Indenture" and
the "Subordinated Debt Indenture," respectively), in each case, between the
Company, as obligor, and The Bank of New York, as Trustee (the "Trustee"). The
Senior Secured Debt Indenture, the Senior Unsecured Debt Indenture, the Senior
Subordinated Debt Indenture and the Subordinated Debt Indenture are sometimes
hereinafter referred to individually as an "Indenture" and collectively as the
"Indentures."
 
    The terms of the Debt Securities include those stated in the applicable
Indenture and those made part of such Indenture by reference to the Trust
Indenture Act, and holders of the Debt Securities are referred
 
                                       9

to the Indentures and the Trust Indenture Act for a statement thereof. A copy of
the form of each Indenture is filed as an exhibit to the Registration Statement
of which this Prospectus is a part. The following summaries of certain
provisions of the Debt Securities and the Indentures, while including a
discussion of all material aspects or features thereof, do not purport to be
complete and are subject to, and are qualified in their entirety by reference
to, all the provisions of the Debt Securities and the Indentures, including the
definitions therein of certain terms which are not otherwise defined in this
Prospectus. Wherever particular provisions or defined terms of the Indentures
are referred to, such provisions or defined terms are incorporated herein by
reference.
 
GENERAL
 
    The Indentures will not limit the aggregate principal amount of Debt
Securities which may be issued thereunder. Debt Securities may be issued
thereunder from time to time as a single series or in two or more separate
series up to the aggregate principal amount from time to time authorized by the
Company for each series.
 
    The applicable Prospectus Supplement or Prospectus Supplements will
describe, among other things, the following terms of the Debt Securities, if
applicable to such Debt Securities: (i) the title of the Debt Securities; (ii)
any limit on the aggregate principal amount of the Debt Securities and whether
they will constitute Senior Secured Debt Securities, Senior Unsecured Debt
Securities, Senior Subordinated Debt Securities or Subordinated Debt Securities;
(iii) the price or prices (expressed as a percentage of the aggregate principal
amount thereof) at which the Debt Securities will be issued; (iv) the date or
dates on which the principal of the Debt Securities is payable or the method of
determination thereof; (v) the rate or rates (which may be fixed or variable) at
which the Debt Securities will bear interest (which rate may be zero in the case
of certain Debt Securities issued at an issue price representing a discount from
the principal amount payable at maturity), and the date or dates from which such
interest, if any, will accrue, and the circumstances, if any, in which the
Company may defer interest payments; (vi) the interest payment date or dates, if
any, on which any interest on the Debt Securities will be payable, and the
record date or dates for any interest payable on any Debt Securities; (vii) the
right or obligation, if any, of the Company to redeem or purchase Debt
Securities pursuant to any sinking fund or analogous provisions or at the option
of a holder thereof, or otherwise, the conditions, if any, giving rise to such
right or obligation, and the period or periods within which, and the price or
prices at which and the terms and conditions upon which Debt Securities shall be
redeemed or purchased, in whole or in part, and any provisions for the marketing
of such Debt Securities; (viii) if the amount of payments of principal of,
premium, if any, and interest, if any, on the Debt Securities is to be
determined by reference to an index, formula or other method, the manner in
which such amounts are to be determined and the calculation agent, if any, with
respect thereto; (ix) if other than the principal amount thereof, the portion of
the principal amount of the Debt Securities which will be payable upon
declaration or acceleration of the stated maturity thereof pursuant to an Event
of Default (as defined in the Indentures); (x) whether the Debt Securities will
be issued in certificated or book-entry form and, if applicable, the identity of
the depositary for the Debt Securities; (xi) any listing of the Debt Securities
on a securities exchange; (xii) any additional restrictive covenants included
for the benefit of holders of such Debt Securities; (xiii) any additional events
of default provided with respect to such Debt Securities; and (xiv) any other
material terms of the Debt Securities. Any such Prospectus Supplement will also
describe any special provisions for the payment of additional amounts with
respect to the Debt Securities.
 
MANDATORY DISPOSITION PURSUANT TO GAMING LAWS
 
    The Indentures will provide that each holder and beneficial owner of Debt
Securities, by accepting or otherwise acquiring an interest in the Debt
Securities, shall be deemed to have agreed that if the Gaming Authority of any
jurisdiction in which the Company or any of its subsidiaries (or any joint
venture in which the Company or a subsidiary of the Company is a participant)
now or hereafter conducts or proposes to conduct gaming requires that a person
who is a holder or beneficial owner of Debt Securities must be licensed,
qualified or found suitable, or comply with any other requirement under
applicable Gaming
 
                                       10

Laws, such holder or beneficial owner shall apply for a license, qualification
or a finding of suitability or comply with such other requirement, as the case
may be, within the prescribed time period. If such holder or beneficial owner
fails to apply to be, or fails to become, licensed or qualified, is found
unsuitable or fails to comply with any other requirement, as the case may be (a
"failure of compliance"), then the Company shall have the right, at its option
(i) to require such person to dispose of its Debt Securities or beneficial
interest therein within 30 days of receipt of notice of the Company's election
or such earlier date as may be requested or prescribed by the Gaming Authority
or (ii) to redeem such Debt Securities (which redemption may be less than 30
days following the notice of redemption if so requested or prescribed by the
Gaming Authority) at a redemption price equal to the lesser of (A) such person's
cost, (B) 100% of the principal amount thereof, plus accrued and unpaid interest
to the earlier of the redemption date and the date of any failure of compliance,
or (C) such lesser amount as may be required by applicable law or by order of
any Gaming Authority. The Company shall notify the Trustee in writing of any
such redemption as soon as practicable. The Company shall not be responsible for
any costs or expenses any such holder or beneficial owner may incur in
connection with its application for a license, qualification or a finding of
suitability or its compliance with any other requirement of a Gaming Authority.
The Indentures will also provide that immediately upon the imposition by a
Gaming Authority of a requirement that a holder or beneficial owner dispose of
Debt Securities, such holder or beneficial owner shall, to the extent required
by applicable Gaming Laws, have no further right (i) to exercise, directly or
indirectly, through any trustee, nominee or any other person or entity, any
right conferred by the Debt Securities or (ii) to receive any interest,
dividends or any other distributions or payments with respect to the Debt
Securities or any remuneration in any form with respect to the Debt Securities
from the Company or the Trustee, except the redemption price referred to above.
 
SUBORDINATION OF SECURITIES
 
    The payment of the principal of, premium, if any, and interest on the
Subordinated Securities will be subordinated in right of payment, as described
below, to the prior payment in full of all current and future Senior
Indebtedness.
 
    The Indentures will provide that in the event of any insolvency or
bankruptcy case or proceeding, or any receivership, liquidation, reorganization
or other similar case or proceeding in connection therewith, relating to the
Company, or any distribution of assets of the Company pursuant to liquidation,
dissolution or other winding-up or reorganization of the Company, whether
voluntary or involuntary, or any assignment for the benefit or creditors or
other marshalling of assets or liabilities of the Company, all Senior
Indebtedness must be paid in full before any payment or distribution is made on
account of the principal of, premium, if any, or interest on the Subordinated
Securities. Upon maturity of any Senior Indebtedness by lapse of time,
acceleration or otherwise, payment in full must be made on such Senior
Indebtedness before any payment is made on or in respect of the Subordinated
Securities. During the continuance of any event of default with respect to
Senior Indebtedness entitling the holders thereof to accelerate the maturity
thereof, or if such event of default would be caused by any payment upon or in
respect of the applicable Subordinated Securities, no payment may be made by the
Company upon or in respect of the Subordinated Securities; provided, however,
that if such event of default is other than a default in payment of any amount
due in connection with such Senior Indebtedness, the Company shall be permitted
to continue to make payments of interest on the Subordinated Securities.
 
    In the event that, notwithstanding the foregoing, the Company makes any
payment or distribution to the Trustee or any holders of any Subordinated
Securities prohibited by the subordination provision of the applicable
Indenture, then such payment or distribution will be required to be paid over
and delivered to the holders (or their representative) of Senior Indebtedness.
 
    If the Company fails to make any payment on Subordinated Securities when due
or within any applicable grace period, whether or not on account of the
subordination provisions referred to above, such failure would constitute an
Event of Default under the Indentures and would enable the holders of such
Subordinated Securities to accelerate the maturity thereof and, subject to the
terms set forth under
 
                                       11

"Events of Default and Notice Thereof," would enable the holders of other Debt
Securities to accelerate the maturity thereof. See "--Events of Default and
Notice Thereof."
 
    By reason of such subordination, in the event of liquidation or insolvency,
creditors of the Company who are holders of Senior Indebtedness may recover
more, ratably, than the holders of the Subordinated Securities and funds that
would be otherwise payable to the holders of the Subordinated Securities will be
paid to the holders of Senior Indebtedness to the extent necessary to pay the
Senior Indebtedness in full, and the Company may be unable to meet its
obligations fully with respect to the Subordinated Securities.
 
    "Capital Lease Obligation" means, at the time any determination thereof is
to be made, the amount of the liability in respect of a capital lease that would
at such time be so required to be capitalized on the balance sheet in accordance
with GAAP.
 
    "Credit Facility" means the Amended and Restated Loan Agreement dated as of
May 23, 1997 among the Company, as Borrower, Bank of America National Trust and
Savings Association, as Administrative Agent, and the lenders which are or
become parties from time to time thereto, as amended by Amendment No. 1 thereto
dated as of October 3, 1997 and Amendment No. 2 thereto dated as of May 15,
1998, together with the related documents thereto (including, without
limitation, any guarantee agreements and security documents), in each case as
such agreements may be amended (including any amendment and restatement
thereof), supplemented or otherwise modified from time to time, including
without limitation any agreement extending the maturity of, refinancing or
otherwise restructuring (including adding guarantors) all or any portion of the
Indebtedness under such agreement or any successor agreement or increasing the
credit available thereunder.
 
    "Interest Rate Protection Obligations" means, with respect to any person,
the obligations of such Person under (i) interest rate swap agreements, interest
rate cap agreements and interest rate collar agreements, and (ii) other
agreements or arrangements designed to protect such person against fluctuations
in interest rates.
 
    "Senior Indebtedness" is defined in the Senior Subordinated Debt Indenture
as the principal, premium, if any, and interest on any Indebtedness of the
Company, whenever created, incurred, issued, assumed or guaranteed, unless, in
the case of any particular Indebtedness, the instrument creating or evidencing
the same or pursuant to which the same is outstanding expressly provides that
such Indebtedness shall not be senior in right of payment to the Senior
Subordinated Debt Securities. Without limiting the foregoing, Senior
Indebtedness shall include (a) the principal of and interest on and other
amounts due on or in connection with the Indebtedness of the Company under the
Credit Facility; (b) all Interest Rate Protection Obligations of the Company;
(c) all obligations of the Company under standby letters of credit; and (d)
Indebtedness evidenced by the Senior Secured Debt Securities, the Senior
Unsecured Debt Securities, the 6.45% Senior Notes of the Company Due 2006, the
7.0% Debentures of the Company Due 2036 and the 6.70% Debentures of the Company
Due 2096. Notwithstanding the foregoing, Senior Indebtedness shall not include
(a) to the extent that it may constitute Indebtedness, any obligation for
federal, state, local or other taxes; (b) any Indebtedness among or between the
Company and/or any one or more subsidiaries and Affiliates of the Company; (c)
to the extent that it may constitute Indebtedness, any obligation in respect to
any trade payable incurred for the purchase of goods or materials, or for
services obtained, in the ordinary course of business; (d) Indebtedness
evidenced by the 6 3/4% Senior Subordinated Notes of the Company Due 2003 and
the 7 5/8% Senior Subordinated Debentures of the Company Due 2013, with respect
to which the Senior Subordinated Debt Securities will rank PARI PASSU in right
of payment; (e) Indebtedness of the Company that is expressly subordinate or
junior in right of payment to any other Indebtedness of the Company; (f) to the
extent that it may constitute Indebtedness, any obligation owing under leases
(other than Capital Lease Obligations) or management agreements; and (g) any
obligation that by operation of law is subordinate to any general unsecured
obligations of the Company; provided, that any guaranty by the Company of
Indebtedness of a subsidiary of the Company to third parties shall constitute
Senior Indebtedness unless, in the case of any particular guaranty, the
instrument creating or evidencing the same provides that such guaranty is
subordinated to any other Indebtedness of the Company; provided further, that in
the event a subsidiary of the Company advances to
 
                                       12

the Company the proceeds attributable to Indebtedness incurred by such
subsidiary to a third party which Indebtedness has been guaranteed by the
Company pursuant to a guaranty which itself constitutes Senior Indebtedness,
then such obligation of the Company to repay such advance to the subsidiary
shall constitute Senior Indebtedness, unless such obligation is created or
evidenced by an instrument which provides that such obligation is subordinated
to any other Indebtedness of the Company.
 
    "Senior Indebtedness" is defined in the Subordinated Debt Indenture as the
principal, premium, if any, and interest on any Indebtedness of the Company,
whenever created, incurred, issued, assumed or guaranteed, unless, in the case
of any particular Indebtedness, the instrument creating or evidencing the same
or pursuant to which the same is outstanding expressly provides that such
Indebtedness shall not be senior in right of payment to the Subordinated Debt
Securities. Without limiting the foregoing, Senior Indebtedness shall include
(a) the principal of and interest on and other amounts due on or in connection
with the Indebtedness of the Company under the Credit Facility; (b) all Interest
Rate Protection Obligations of the Company; (c) all obligations of the Company
under standby letters of credit; (d) Indebtedness evidenced by the Senior
Subordinated Debt Securities, the 6 3/4% Senior Subordinated Notes of the
Company Due 2003 and the 7 5/8% Senior Subordinated Debentures of the Company
Due 2013; and (e) Indebtedness evidenced by the Senior Secured Debt Securities,
the Senior Unsecured Debt Securities, the 6.45% Senior Notes of the Company Due
2006, the 7.0% Debentures of the Company Due 2036 and the 6.70% Debentures of
the Company Due 2096. Notwithstanding the foregoing, Senior Indebtedness shall
not include (a) to the extent that it may constitute Indebtedness, any
obligation for federal, state, local or other taxes; (b) any Indebtedness among
or between the Company and/or any one or more subsidiaries or Affiliates of the
Company; (c) to the extent that it may constitute Indebtedness, any obligation
in respect to any trade payable incurred for the purchase of goods or materials,
or for services obtained, in the ordinary course of business; (d) to the extent
that it may constitute Indebtedness, any obligation owing under leases (other
than Capital Lease obligations) or management agreements; and (e) any obligation
that by operation of law is subordinate to any general unsecured obligations of
the Company; provided, that any guaranty by the Company of Indebtedness of a
subsidiary of the Company to third parties shall constitute Senior Indebtedness
unless, in the case of any particular guaranty, the instrument creating or
evidencing the same provides that such guaranty does not constitute Senior
Indebtedness; provided further, that in the event a subsidiary of the Company
advances to the Company the proceeds attributable to Indebtedness incurred by
such subsidiary to a third party which Indebtedness has been guaranteed by the
Company pursuant to a guaranty which itself constitutes Senior Indebtedness,
then such obligation of the Company to repay such advance to the subsidiary
shall constitute Senior Indebtedness, unless such obligation is created or
evidenced by an instrument which provides that such advance does not constitute
Senior Indebtedness.
 
    The claims of third parties to the assets of the Company's subsidiaries
incurring such obligations will be superior to those of the Company as a
stockholder and, therefore, the Debt Securities may be deemed to be effectively
subordinated to the claims of such third parties. Substantially all of the
Company's business operations are conducted through such subsidiaries, and the
Debt Securities are effectively subordinated to the repayment of the liabilities
arising from those operations. Unless the Prospectus Supplement otherwise
provides, the Indentures will not limit the amount of additional Indebtedness,
including Senior Indebtedness, which the Company or any subsidiary may create,
incur, assume or guarantee. As a result of the subordination provisions
contained in the Indentures, in the event of insolvency, holders of the
Subordinated Securities may recover less, ratably, than other creditors of the
Company or its subsidiaries.
 
REGISTERED GLOBAL SECURITIES
 
    The registered Debt Securities of a series may be issued in the form of one
or more Registered Global Securities that will be deposited with and registered
in the name of a depositary (a "Depositary") or its nominee identified in the
applicable Prospectus Supplement. In such case, one or more Registered Global
Securities will be issued in a denomination or aggregate denominations equal to
the portion of the aggregate principal amount of outstanding registered Debt
Securities of the series to be represented by
 
                                       13

such Registered Global Security or Securities. Unless and until it is exchanged
in whole or in part for Debt Securities in definitive registered form, a
Registered Global Security may not be transferred except as a whole by the
Depositary for such Registered Global Security to a nominee of such Depositary,
or by such a nominee to such Depositary or to another nominee of such
Depositary, or by such Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary.
 
    The specific terms of the depositary arrangement with respect to any portion
of a series of Debt Securities to be represented by a Registered Global Security
will be described in the applicable Prospectus Supplement. The Company
anticipates that the following provisions will apply to all depositary
arrangements.
 
    Ownership of beneficial interests in a Registered Global Security will be
limited to persons that have accounts with the Depositary for such Registered
Global Security ("participants") or persons holding interests through
participants. Upon the issuance of a Registered Global Security, the Depositary
for such Registered Global Security will credit, on its book-entry registration
and transfer system, the participants' accounts with the respective principal
amounts of the Debt Securities represented by such Registered Global Security
beneficially owned by such participants. The accounts to be credited shall be
designated by any dealers, underwriters or agents participating in the
distribution of such Debt Securities. Ownership of beneficial interests in such
Registered Global Security will be shown on, and the transfer of such ownership
interests will be effected only through, records maintained by the Depositary
for such Registered Global Security (with respect to interests of participants)
and on the records of participants (with respect to interests of persons holding
through participants). The laws of some states may require that certain
purchasers of securities take physical delivery of such securities in definitive
form. Such limits and such laws may impair the ability to own, transfer or
pledge beneficial interests in Registered Global Securities.
 
    So long as the Depositary for a Registered Global Security, or its nominee,
is the registered owner of such Registered Global Security, such Depositary or
such nominee, as the case may be, will be considered the sole owner or holder of
the Debt Securities represented by such Registered Global Security for all
purposes under the Indentures. Except as set forth below, owners of beneficial
interests in a Registered Global Security will not be entitled to have the Debt
Securities represented by such Registered Global Security registered in their
names, will not receive or be entitled to receive physical delivery of such Debt
Securities in definitive form and will not be considered the owners or holders
thereof under the Indentures. Accordingly, each person owning a beneficial
interest in a Registered Global Security must rely on the procedures of the
Depositary for such Registered Global Security and, if such person is not a
participant, on the procedures of the participant through which such person owns
its interests, to exercise any rights of a holder under the Indentures. The
Company understands that under existing industry practices, if the Company
requests any action of holders or if an owner of a beneficial interest in a
Registered Global Security desires to give or take any action which a holder is
entitled to give or take under the applicable Indenture, the Depositary for such
Registered Global Security would authorize the participants holding the relevant
beneficial interests to give or take such action, and such participants would
authorize beneficial owners owning through such participants to give or take
such action or would otherwise act upon the instructions of beneficial owners
holding through them.
 
    Principal, premium, if any, and interest payments on Debt Securities
represented by a Registered Global Security registered in the name of a
Depositary or its nominee will be made to such Depositary or its nominee, as the
case may be, as the registered owner of such Registered Global Security. None of
the Company, the Trustee or any other agent of the Company or agent of the
Trustee will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests in
such Registered Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
 
    The Company expects that the Depositary for any Debt Securities represented
by a Registered Global Security, upon receipt of any payment of principal,
premium or interest in respect of such Registered Global Security, will
immediately credit participants' accounts with payments in amounts proportionate
to their respective beneficial interests in such Registered Global Security as
shown on the records of such
 
                                       14

Depositary. The Company also expects that payments by participants to owners of
beneficial interests in such Registered Global Security held through such
participants will be governed by standing customer instructions and customary
practices, as is now the case with the securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of such participants.
 
    If the Depositary for any Debt Securities represented by a Registered Global
Security is at any time unwilling or unable to continue as Depositary or ceases
to be a clearing agency registered under the Exchange Act, and a successor
Depositary registered as a clearing agency under the Exchange Act is not
appointed by the Company within 90 days, the Company will issue such Debt
Securities in definitive form in exchange for such Registered Global Security.
In addition, the Company may at any time and in its sole discretion determine
not to have any of the Debt Securities of a series represented by one or more
Registered Global Securities and, in such event, will issue Debt Securities of
such series in definitive form in exchange for all of the Registered Global
Security or Securities representing such Debt Securities. Any Debt Securities
issued in definitive form in exchange for a Registered Global Security will be
registered in such name or names as the Depositary shall instruct the Trustees.
It is expected that such instructions will be based upon directions received by
the Depositary from participants with respect to ownership of beneficial
interests in such Registered Global Security.
 
CERTAIN COVENANTS
 
    LIMITATION OF LIENS.  Unless otherwise indicated in the applicable
Prospectus Supplement, the Senior Unsecured Debt Indenture and the Senior
Subordinated Debt Indenture will provide that neither the Company nor any of its
subsidiaries may issue, assume or guarantee any Indebtedness secured by a Lien
upon any Consolidated Property without effectively providing that the Debt
Securities shall be secured equally and ratably with (or prior to) such
Indebtedness so long as such Indebtedness shall be so secured, except that this
restriction will not apply to: (a) Liens existing on the date of original
issuance of the Debt Securities; (b) Liens affecting property of a corporation
or other entity existing at the time it becomes a subsidiary of the Company or
at the time it is merged into or consolidated with the Company or a subsidiary
of the Company; (c) Liens on property existing at the time of acquisition
thereof or incurred to secure payment of all or a part of the purchase price
thereof or to secure Indebtedness incurred prior to, at the time of, or within
24 months after the acquisition thereof for the purpose of financing all or part
of the purchase price thereof; (d) Liens on any property to secure all or part
of the cost of improvements or construction thereon or Indebtedness incurred to
provide funds for such purpose in a principal amount not exceeding the cost of
such improvements or construction; (e) Liens which secure Indebtedness owing by
a subsidiary of the Company to the Company or to a subsidiary of the Company;
(f) Liens securing Indebtedness of the Company the proceeds of which are used
substantially simultaneously with the incurrence of such Indebtedness to retire
Funded Debt; (g) purchase money security Liens on personal property; (h) Liens
securing Indebtedness of the Company the proceeds of which are used within 24
months of the incurrence of such Indebtedness for the Project Cost of the
construction and development or improvement of a Resort Property; (i) Liens on
the stock, partnership or other equity interest of the Company or any subsidiary
in any Joint Venture (as hereinafter defined) or any subsidiary which owns an
equity interest in such Joint Venture to secure Indebtedness, PROVIDED the
amount of such Indebtedness is contributed and/or advanced solely to such Joint
Venture; (j) Liens securing any Senior Indebtedness (as defined in the Senior
Subordinated Debt Indenture), including without limitation, the Senior Secured
Debt Securities; (k) certain Liens to government entities, including pollution
control or industrial revenue bond financing; (l) Liens required by any contract
or statute in order to permit the Company or a subsidiary of the Company to
perform any contract or subcontract made by it with or at the request of a
governmental entity; (m) mechanic's, materialman's, carrier's or other like
Liens, arising in the ordinary course of business; (n) certain Liens for taxes
or assessments and similar charges; (o) zoning restrictions, easements,
licenses, covenants, reservations, restrictions on the use of real property and
certain other minor irregularities of title; and (p) certain extensions,

on the property to be leased, without equally and ratably securing such Debt
Securities or (b) the Company within 120 days after the effective date of such
Sale and Lease-Back Transaction applies to the voluntary retirement of its
Funded Debt an amount equal to the Value of the Sale and Lease-Back Transaction

EVENTS OF DEFAULT AND NOTICE THEREOF
 
    Unless otherwise indicated in the applicable Prospectus Supplement, the term
"Event of Default," when used in an Indenture with respect to any series of Debt
Securities, will mean any one of the following: (i) failure of the Company to
pay (whether or not prohibited by the subordination provisions (if any))
interest for 30 days on, or the principal when due of, such series of Debt
Securities; (ii) failure to perform any other covenant contained in such
Indenture for 30 days after notice; (iii) the occurrence of an event of default
under any instrument evidencing Indebtedness of the Company or its subsidiaries
entitling the holder or holders thereof to accelerate the payment of an
aggregate principal amount of $10,000,000 or more of such Indebtedness, which
event of default is not cured or waived in accordance with the provisions of
such instrument, or such Indebtedness is not discharged, within 30 days after
the receipt by the Company of notice from the Trustee or the holders of 25% in
principal amount of such series of Debt Securities then outstanding of such
event of default and requiring the Company to cause such event of default to be
cured or such Indebtedness to be discharged; and (iv) certain events of
bankruptcy, insolvency or reorganization.
 
    The Indentures will provide that the Trustee will, within 90 days after the
occurrence of a default that is known to the Trustee with respect to any series
of Debt Securities, give the holders of such series of Debt Securities notice of
such default (the term "default" to include the events specified above without
grace or notice), PROVIDED, that, except in the case of default in the payment
of principal of or interest on such series of Debt Securities, the Trustee shall
be protected in withholding such notice if it in good faith determines that the
withholding of such notice is in the interest of the holders of such series of
Debt Securities.
 
    In case an Event of Default occurs and is continuing with respect to any
series of Debt Securities, the Trustee or the holders of not less than 25% in
principal amount of such series of Debt Securities, by notice in writing to the
Company (and to the Trustee if given by the holders of such series of Debt
Securities), may declare the principal of and all accrued interest on all such
series of Debt Securities (but in no event more than the maximum amount of
principal and interest thereon allowed by law) to be due and payable
immediately. Such declaration may be rescinded by holders of a majority in
principal amount of such series of Debt Securities then outstanding if, among
other conditions, all existing Events of Default relating to such series of Debt
Securities have been cured or waived and if the rescission would not conflict
with any judgment or decree.
 
    Defaults with respect to any series of Debt Securities (except, unless
theretofore cured, a default in payment of principal of or interest on such
series of Debt Securities or default with respect to a provision which cannot be
modified under the terms of the applicable Indenture without the consent of each
holder of the Debt Securities affected) may be waived by the holders of a
majority in principal amount of such series of Debt Securities then outstanding
upon the conditions provided in such Indenture.
 
    The Indentures will include a covenant that the Company will file annually
with the Trustee a statement regarding compliance by the Company with the terms
thereof and specifying any defaults of which the signers may have knowledge.
 
MODIFICATION OF THE INDENTURES
 
    Under the Indentures, the rights and obligations of the Company and the
rights of the holders of the Debt Securities may be modified by the Company and
the Trustee only with the consent of the holders of not less than a majority in
principal amount of the class of Debt Securities then outstanding affected by
such modification; but no reduction in the principal, or extension of the
maturity, of any Debt Securities in a manner adverse to the holders of the Debt
Securities, or reduction of the interest rate or extension of the time of
payment of interest on the Debt Securities in a manner adverse to the holders of
the Debt Securities, or any modification of the subordination provisions (if
any) in a manner adverse to the holders of the Debt Securities, or reduction of
the percentage required for modification, will be effective against any holder
of the Debt Securities without such holder's consent. Under certain
circumstances, however,
 
                                       19

the Company may amend or supplement the Indentures without notice to or the
consent of any holders of the Debt Securities.
 
SATISFACTION AND DISCHARGE OF INDENTURES
 
    Unless otherwise indicated in the applicable Prospectus Supplement, each
Indenture with respect to any series of Debt Securities will be discharged upon
payment in full of such series of Debt Securities outstanding thereunder, or
upon the deposit with the Trustee, in trust, of money and/or U.S. Government
Obligations which through the payment of interest and principal in respect
thereof in accordance with their terms will, without consideration of any
reinvestment of such interest, provide money in an amount sufficient to pay and
discharge the principal of and each installment of interest on such series of
Debt Securities on the maturity or redemption date, as the case may be, of such
payments in accordance with the terms of the applicable Indenture and such
series of Debt Securities issued thereunder. The Company will be entitled to
make such a deposit if, among other things, the Company has delivered to the
Trustee an Opinion of Counsel, reasonably satisfactory to the Trustee, to the
effect that (i) the holders of such series of Debt Securities will not recognize
income, gain or loss for federal income tax purposes as a result of such deposit
and defeasance of the applicable Indenture and will be subject to federal income
tax on the same amount and in the same manner and at the same times as would
have been the case if such deposit and defeasance had not occurred and (ii) the
trust funds will not be subject to the effect of any applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally.
 
COVENANT DEFEASANCE
 
    Unless otherwise indicated in the applicable Prospectus Supplement, each
Indenture will provide that the Company may be released from its obligations
with respect to any series of Debt Securities relating to the Company's
obligations with respect to the payment of taxes and other claims, maintenance
of properties, limitations on Liens, limitations on sale and lease-back
transactions, limitations on when the Company may merge and any other covenants
specified in any Prospectus Supplement, and that such release will not be deemed
to be an Event of Default under such Indenture with respect to any series of
Debt Securities ("covenant defeasance"), upon the deposit with the Trustee (or
other qualifying trustee), in trust, of money and/or U.S. Government Obligations
which through the payment of interest and principal in respect thereof in
accordance with their terms will, without consideration of any reinvestment of
such interest, provide money in an amount sufficient to pay and discharge the
principal of and each installment of interest on such series of Debt Securities
on the maturity of such payments in accordance with the terms of the applicable
Indenture and such series of Debt Securities issued thereunder. The Company will
be entitled to make such a deposit if, among other things, the Company has
delivered to the Trustee an Opinion of Counsel, reasonably satisfactory to the
Trustee, to the effect that (i) the holders of such series of Debt Securities
will not recognize income, gain or loss for federal income tax purposes as a
result of such covenant defeasance of certain obligations and will be subject to
federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such covenant defeasance had not occurred and
(ii) the trust funds will not be subject to the effect of any applicable
bankruptcy, insolvency, reorganization or similar laws affecting creditors'
rights generally.
 
CONCERNING THE TRUSTEE
 
    Unless otherwise indicated in the applicable Prospectus Supplement, the Bank
of New York will be the Trustee under each of the Indentures. All payments of
principal of, and interest on, and all registration, transfer, exchange,
authentication, and delivery of, the Debt Securities (including authentication
and delivery on original issuance of the Debt Securities) will be effected by
the Trustee in New York, New York.
 
    Each Indenture will contain certain limitations on the right of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases or to realize on certain property received in
 
                                       20

respect of any such claim as security or otherwise. The Trustee will be
permitted to engage in other transactions; however, if it acquires any
conflicting interest it must eliminate such conflict or resign.
 
    The Trustee, as successor in interest to Wells Fargo Bank (Colorado), N.A.,
which was successor in interest to First Interstate Bank of Nevada, N.A., also
serves as a trustee with respect to the 6.45% Senior Notes of the Company Due
2006, the 6 3/4% Senior Subordinated Notes of the Company Due 2003, the 7 5/8%
Senior Subordinated Debentures of the Company Due 2013, the 7.0% Debentures of
the Company due 2036, and the 6.70% Debentures of the Company due 2096. In case
of any conflicting interest relating to the Trustee's duties with respect to the
foregoing securities or the Debt Securities, the Trustee shall either eliminate
such conflicting interest or, except as otherwise provided in the Trust
Indenture Act, resign.
 
    The holders of a majority in principal amount of any series of Debt
Securities then outstanding will have the right to direct the time, method and
place of conducting any proceeding for exercising any remedy available to the
Trustee with respect to such series of Debt Securities, PROVIDED that such
direction would not conflict with any rule of law or with the applicable
Indenture, would not be unduly prejudicial to the rights of another holder of
the Debt Securities, and would not involve the Trustee in personal liability.
The Indentures will provide that in case an Event of Default shall occur and be
known to the Trustee (and not be cured), the Trustee will be required to use the
degree of care of a prudent man in the conduct of his own affairs in the
exercise of its power. Subject to such provisions, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indentures at the
request of any of the holders of the Debt Securities, unless they shall have
offered to the Trustee security and indemnity satisfactory to it.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, STOCKHOLDERS OR INCORPORATORS
 
    The Indentures will provide that no past, present or future director,
officer, employee, stockholder or incorporator of the Company or any successor
corporation shall have any liability for any obligations of the Company under
the Debt Securities or the Indentures or for any claim based on, in respect of,
or by reason of such obligations or their creation, by reason of such person's
or entity's status as such director, officer, employee, stockholder or
incorporator.
 
CREDIT FACILITY
 
    The Company's Credit Facility includes covenants which limit the respective
levels of "Senior Debt" and "Total Debt" (each as defined in the Credit
Facility) which may be incurred or maintained by the Company based on its
"Adjusted EBITDA" (as defined in the Credit Facility). Accordingly, the
Company's ability to issue Debt Securities, or Debt Securities constituting
senior indebtedness, may be limited by the Credit Facility.
 
                                       21

                 DESCRIPTION OF THE TRUST PREFERRED SECURITIES
 
    Each Trust may issue only one series of Trust Preferred Securities having
terms described in the Prospectus Supplement relating thereto. The Declaration
of each Trust authorizes the Regular Trustees of such Trust to issue on behalf
of such Trust one series of Trust Preferred Securities. Each Declaration will be
qualified as an indenture under the Trust Indenture Act. The Trust Preferred
Securities will have such terms, including distributions, redemption, voting,
liquidation rights and such other preferred, deferred or other special rights or
such restrictions as shall be set forth in each Declaration or made part of each
Declaration by the Trust Indenture Act and the Trust Act. Reference is made to
the Prospectus Supplement relating to the Trust Preferred Securities of a Trust
for specific terms, including (i) the distinctive designation of such Trust
Preferred Securities; (ii) the number of Trust Preferred Securities issued by
such Trust; (iii) the annual distribution rate (or method of determining such
rate) for Trust Preferred Securities issued by such Trust and the date or dates
upon which such distributions shall be payable; PROVIDED, HOWEVER, that
distributions on such Trust Preferred Securities shall be payable on a quarterly
basis to holders of such Trust Preferred Securities as of a record date in each
quarter during which such Trust Preferred Securities are outstanding; (iv)
whether distributions on Trust Preferred Securities issued by such Trust shall
be cumulative, and, in the case of Trust Preferred Securities having such
cumulative distribution rights, the date or dates or method of determining the
date or dates from which distributions on Trust Preferred Securities issued by
such Trust shall be cumulative; (v) the amount or amounts which shall be paid
out of the assets of such Trust to purchase or redeem Trust Preferred Securities
issued by such Trust and the price or prices at which, the period or periods
within which, and the terms and conditions upon which, Trust Preferred
Securities issued by such Trust shall be purchased or redeemed, in whole or in
part, pursuant to such obligation; (vi) the voting rights, if any, of Trust
Preferred Securities issued by such Trust in addition to those required by law,
including any requirement for the approval by the holders of Trust Preferred
Securities, or of Trust Preferred Securities issued by one or more Trusts, or of
both, as a condition to specified action or amendments to the Declaration of
such Trust; (vii) whether the Trust Preferred Securities will be issued in
certificated or book-entry form and, if applicable, the identity of the
depositary for the Trust Preferred Securities and (viii) any other relevant
rights, preferences, privileges, limitations or restrictions of Trust Preferred
Securities issued by such Trust not inconsistent with the Declaration of such
Trust or with applicable law. All Trust Preferred Securities offered hereby will
be guaranteed by the Company as described under "Description of the Trust
Preferred Securities Guarantees". Any applicable United States federal income
tax considerations applicable to any offering of Trust Preferred Securities will
be described in the Prospectus Supplement relating thereto.
 
    In connection with the issuance of Trust Preferred Securities, each Trust
will issue one series of Trust Common Securities. The Declaration of each Trust
authorizes the Regular Trustees of such Trust to issue on behalf of such Trust
one series of Trust Common Securities having such terms including distributions,
redemption, voting, liquidation rights or such restrictions as shall be set
forth therein. The terms of the Trust Common Securities issued by a Trust will
be substantially identical to the terms of the Trust Preferred Securities issued
by such Trust and the Trust Common Securities will rank PARI PASSU, and payments
will be made thereon pro rata, with the Trust Preferred Securities except that,
upon the occurrence and during the continuation of an event of default under the
Declaration, the rights of the holders of the Common Securities to payment in
respect of distributions and payments upon liquidation, redemption and otherwise
will be subordinated to the rights of the holders of the Trust Preferred
Securities. All of the Trust Common Securities of a Trust will be directly or
indirectly owned by the Company.
 
    Trust Preferred Securities will be issued in registered form and in either
certificated form or represented by one or more global securities. If Trust
Preferred Securities are represented by one or more global securities (each, a
"Global Security"), the applicable Prospectus Supplement will describe the
circumstances, if any, under which beneficial owners of interests in any such
Global Security may exchange such interests for Trust Preferred Securities of
like tenor and amount in any authorized form and denomination. The specific
terms of any depositary arrangement with respect to Trust Preferred Securities
 
                                       22

to be represented by a Global Security will be described in the applicable
Prospectus Supplement. Reference is made to "Description of Debt
Securities--Registered Global Securities" for a description of provisions the
Company anticipates will apply to all depositary arrangements, including those
relating to Trust Preferred Securities.
 
    The Declaration of Trust of each Trust will provide that each holder and
beneficial owner of Trust Preferred Securities, by accepting or otherwise
acquiring an interest in the Trust Preferred Securities, shall be deemed to have
agreed that if the Gaming Authority of any jurisdiction in which the Company or
any of its subsidiaries (or any joint venture in which the Company or a
subsidiary of the Company is a participant) now or hereafter conducts or
proposes to conduct gaming requires that a person who is a holder or beneficial
owner of Trust Preferred Securities must be licensed, qualified or found
suitable, or comply with any other requirement under applicable Gaming Laws,
such holder or beneficial owner shall apply for a license, qualification or a
finding of suitability or comply with such other requirement, as the case may
be, within the prescribed time period. If such holder or beneficial owner fails
to apply to be, or fails to become, licensed or qualified, is found unsuitable
or fails to comply with any other requirement, as the case may be (a "failure of
compliance"), then the Company shall have the right, at its option (i) to
require such person to dispose of its Trust Preferred Securities or beneficial
interest therein within 30 days of receipt of notice of the Company's election
or such earlier date as may be requested or prescribed by the Gaming Authority
or (ii) to purchase such Trust Preferred Securities (which purchase may be less
than 30 days following the notice of purchase if so requested or prescribed by
the Gaming Authority) at a purchase price equal to the lesser of (A) such
person's cost, (B) 100% of the liquidation amount thereof, plus accrued and
unpaid cash distributions to the earlier of the purchase date and the date of
any failure of compliance, or (C) such other amount as may be required by
applicable law or by order of any Gaming Authority. The Company shall notify the
trustees under the applicable Declaration of Trust in writing of any such
purchase as soon as practicable. Neither the Company nor the Trust shall be
responsible for any costs or expenses any such holder or beneficial owner may
incur in connection with its application for a license, qualification or a
finding of suitability or its compliance with any other requirement of a Gaming
Authority. The Declaration of Trust of each Trust will also provide that
immediately upon the imposition by a Gaming Authority of a requirement that a
holder or beneficial owner dispose of Trust Preferred Securities, such holder or
beneficial owner shall, to the extent required by applicable Gaming Laws, have
no further right (i) to exercise, directly or indirectly, through any trustee,
nominee or any other person or entity, any right conferred by the Trust
Preferred Securities or (ii) to receive any cash distributions, interest,
dividends or any other distributions or payments with respect to the Trust
Preferred Securities or any remuneration in any form with respect to the Trust
Preferred Securities from the Company, the Trust or the trustees under the
applicable Declaration of Trust, except the purchase price referred to above.
 
            DESCRIPTION OF THE TRUST PREFERRED SECURITIES GUARANTEES
 
    Set forth below is a summary of information concerning the Trust Preferred
Securities Guarantees which will be executed and delivered by the Company for
the benefit of the holders from time to time of Trust Preferred Securities. Each
Trust Preferred Securities Guarantee will be qualified as an indenture under the
Trust Indenture Act. The Bank of New York will act as indenture trustee under
each Trust Preferred Securities Guarantee (the "Preferred Guarantee Trustee").
The terms of each Preferred Securities Guarantee will be those set forth in such
Trust Preferred Securities Guarantee and those made part of such Preferred
Securities Guarantee by the Trust Indenture Act. The following summary does not
purport to be complete and is subject in all respects to the provisions of, and
is qualified in its entirety by reference to, the form of Trust Preferred
Securities Guarantee, which is filed as an exhibit to the Registration Statement
of which this Prospectus forms a part, and the Trust Indenture Act. Each Trust
Preferred Securities Guarantee will be held by the Preferred Guarantee Trustee
for the benefit of the holders of the Trust Preferred Securities of the
applicable Trust.
 
                                       23

GENERAL
 
    Pursuant to each Trust Preferred Securities Guarantee, the Company will
irrevocably and unconditionally agree to pay in full, to the holders of the

of any defense, right to set-off or counterclaim which such Trust may have or
assert. The following payments with respect to Preferred Securities issued by a

extent such Trust has funds available therefor, with respect to any Preferred
Securities called for redemption by such Trust and (iii) upon a voluntary or
involuntary termination, dissolution or winding-up of such Trust (other than in
connection with the distribution of Subordinated Deferrable Interest Debentures
to the holders of Trust Preferred Securities in exchange for their Trust
Preferred Securities), the lesser of (a) the aggregate of the liquidation amount
and all accrued and unpaid distributions on such Trust Preferred Securities to
the date of payment, to the extent such Trust shall have funds available
therefor, and (b) the amount of assets of such Trust remaining available for
distribution to holders of such Trust Preferred Securities in liquidation of
such Trust. The Company's obligation to make a Guarantee Payment may be
satisfied by direct payment of the required amounts by the Company to the
holders of Trust Preferred Securities or by causing the applicable Trust to pay
such amounts to such holders.
 
    Each Trust Preferred Securities Guarantee will be a full and unconditional
guarantee with respect to the Trust Preferred Securities issued by the
applicable Trust from the time of issuance of such Trust Preferred Securities,
but will not apply to any payment of distributions when the Trust does not have
sufficient funds available to make such payment or distributions. If the Company
does not make interest payments on the Subordinated Deferrable Interest
Debentures purchased by a Trust, such Trust will not pay distributions on the
Trust Preferred Securities issued by such Trust and will not have funds
available therefor. See "Description of the Subordinated Deferrable Interest
Debentures--Certain Covenants."
 
    The Company has also agreed separately to guarantee the obligations of the
Trusts with respect to the Trust Common Securities (the "Trust Common Securities
Guarantees") to the same extent as the Trust Preferred Securities Guarantee,
except that upon the occurrence and during the continuation of an event of
default under the Subordinated Debentures Indenture (as hereinafter defined),
holders of Trust Preferred Securities shall have priority over holders of Trust
Common Securities with respect to distributions and payments on liquidation,
redemption or otherwise.
 
    For information concerning the requirement that Trust Preferred Securities
be disposed of by holders or beneficial owners under certain circumstances, see
"Description of the Trust Preferred Securities."
 
CERTAIN COVENANTS OF THE COMPANY
 
    In each Trust Preferred Securities Guarantee, the Company will covenant
that, so long as any Trust Preferred Securities issued by the applicable Trust
remain outstanding, if any event that would constitute an event of default shall
exist under such Trust Preferred Securities Guarantee or the Declaration of such
Trust, then (a) the Company shall not declare or pay any dividend on, make any
distributions with respect to, or redeem, purchase or make a liquidation payment
with respect to, any of its capital stock, (b) the Company shall not make any
payment of interest, principal or premium, if any, on or repay, repurchase or
redeem any debt securities issued by the Company which rank PARI PASSU with or
junior to such Subordinated Deferrable Interest Debentures and (c) the Company
shall not make any guarantee payments (other than pursuant to the Trust
Preferred Security Guarantees) with respect to the foregoing. However, each
Trust Preferred Security Guarantee will except from the foregoing covenant any
dividend, redemption, liquidation, interest, principal or guarantee payment by
the Company where the payment is
 
                                       24

made by way of securities (including capital stock) that rank junior to the
securities on which such dividend, redemption, liquidation, interest, principal
or guarantee payment is being made.
 
MODIFICATION OF THE TRUST PREFERRED SECURITIES GUARANTEES; ASSIGNMENT
 
    Except with respect to any changes which do not adversely affect the rights
of holders of Trust Preferred Securities (in which case no vote will be
required), each Trust Preferred Securities Guarantee may be amended only with
the prior approval of the holders of not less than a majority in aggregate
liquidation amount of the outstanding Trust Preferred Securities issued by the
applicable Trust. The manner of obtaining any such approval of holders of such
Trust Preferred Securities will be as set forth in an accompanying Prospectus
Supplement. All guarantees and agreements contained in a Trust Preferred
Securities Guarantee shall bind the successors, assigns, receivers, trustees and
representatives of the Company and shall inure to the benefit of the holders of
the Trust Preferred Securities then outstanding of the applicable Trust.
 
TERMINATION
 
    Each Trust Preferred Securities Guarantee will terminate as to the Trust
Preferred Securities issued by the applicable Trust upon full payment of the
Redemption Price of all Trust Preferred Securities of such Trust, upon
distribution of the Subordinated Deferrable Interest Debentures held by such
Trust to the holders of the Trust Securities of such Trust in liquidation of
such holders' interest in such Trust Securities or upon full payment of the
amounts payable in accordance with the Declaration of such Trust upon
liquidation of such Trust. Each Trust Preferred Securities Guarantee will
continue to be effective or will be reinstated, as the case may be, if at any
time any holder of Trust Preferred Securities issued by the applicable Trust
must restore payment of any sums paid under such Trust Preferred Securities or
such Trust Preferred Securities Guarantee.
 
EVENTS OF DEFAULT
 
    An event of default under a Trust Preferred Securities Guarantee will occur
upon the failure of the Company to perform any of its payment or other
obligations thereunder.
 
    The holders of a majority in liquidation amount of the Trust Preferred
Securities relating to such Trust Preferred Securities Guarantee have the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Preferred Guarantee Trustee in respect of such Trust Preferred
Securities Guarantee or to direct the exercise of any trust or power conferred
upon the Trust Preferred Guarantee Trustee under such Trust Preferred Securities
Guarantee. If the Preferred Guarantee Trustee fails to enforce such Trust
Preferred Securities Guarantee, any holder of Trust Preferred Securities
relating to such Trust Preferred Securities Guarantee may institute a legal
proceeding directly against the Company to enforce the Preferred Guarantee
Trustee's rights under such Trust Preferred Securities Guarantee, without first
instituting a legal proceeding against the relevant Trust, the Preferred
Guarantee Trustee or any other person or entity. In addition, any record holder
of Trust Preferred Securities relating to such Trust Preferred Securities
Guarantee shall have the right, which is absolute and unconditional, to proceed
directly against the Company to obtain Guarantee Payments thereunder, without
first waiting to determine if the Preferred Guarantee Trustee has enforced such
Trust Preferred Security Guarantee or instituting a legal proceeding against the
Trust which issued such Trust Preferred Securities, the Preferred Guarantee
Trustee or any other person or entity.
 
STATUS OF THE TRUST PREFERRED SECURITIES GUARANTEES
 
    The Trust Preferred Securities Guarantees will constitute unsecured
obligations of the Company and will rank (i) subordinate and junior in right of
payment to all other liabilities of the Company, (ii) PARI PASSU with the most
senior preferred or preference stock now or hereafter issued by the Company and
with any guarantee now or hereafter entered into by the Company in respect of
any preferred or preference stock of any subsidiary or affiliate of the Company
and (iii) senior to the Company's common stock. The
 
                                       25

terms of the Trust Preferred Securities provide that each holder of Trust
Preferred Securities issued by such Trust by acceptance thereof agrees to the
subordination provisions and other terms of the Trust Preferred Securities
Guarantee relating thereto.
 
    The Trust Preferred Securities Guarantees will constitute a guarantee of
payment and not of collection (that is, the guaranteed party may institute a
legal proceeding directly against the guarantor to enforce its rights under the
guarantee without instituting a legal proceeding against any other person or
entity).
 
    The Company's obligations under the Declaration for each Trust, the Trust
Preferred Securities Guarantee with respect to the Trust Preferred Securities
issued by such Trust, the Subordinated Deferrable Interest Debentures purchased
by such Trust and the Subordinated Debentures Indenture, in the aggregate, will
provide a full and unconditional guarantee by the Company of payments due on the
Trust Preferred Securities issued by such Trust.
 
INFORMATION CONCERNING THE PREFERRED GUARANTEE TRUSTEE
 
    The Preferred Guarantee Trustee, prior to the occurrence of a default with
respect to a Trust Preferred Securities Guarantee, undertakes to perform only
such duties as are specifically set forth in such Trust Preferred Securities
Guarantee and, after default, shall exercise the same degree of care as a
prudent individual would exercise in the conduct of is or her own affairs.
Subject to such provisions, the Preferred Guaranteed Trustee is under no
obligation to exercise any of the powers vested in it by the Trust Preferred
Securities Guarantee at the request of any holder of Trust Preferred Securities,
unless offered reasonable indemnity against the costs, expenses and liabilities
which might be incurred thereby.
 
    The Preferred Guarantee Trustee serves as trustee under other indentures
pursuant to which unsecured debt securities of the Company are outstanding.
 
GOVERNING LAW
 
    The Trust Preferred Securities Guarantees will be governed by and construed
in accordance with the internal laws of the State of New York.
 
         DESCRIPTION OF THE SUBORDINATED DEFERRABLE INTEREST DEBENTURES
 
    Subordinated Deferrable Interest Debentures may be issued from time to time
in one or more series under an Indenture (the "Subordinated Debentures
Indenture") to be entered into among the Company and The Bank of New York, as
Trustee (the "Subordinated Debentures Trustee"). The terms of the Subordinated
Deferrable Interest Debentures will include those stated in the Subordinated
Debentures Indenture and in a Supplemental Subordinated Debentures Indenture (as
defined below) and those made part of the Subordinated Debentures Indenture by
reference to the Trust Indenture Act. The following summary does not purport to
be complete and is subject in all respects to the provisions of, and is
qualified in its entirety by reference to, the form of Subordinated Debentures
Indenture, which is filed as an exhibit to the Registration Statement of which
this Prospectus forms a part, and the Trust Indenture Act. Whenever particular
provisions or defined terms in the Subordinated Debentures Indenture are
referred to herein, such provisions or defined terms are incorporated by
reference herein.
 
GENERAL
 
    The Subordinated Deferrable Interest Debentures will be unsecured
subordinated obligations of the Company. The Subordinated Debentures Indenture
does not limit the aggregate principal amount of Subordinated Deferrable
Interest Debentures which may be issued thereunder and provides that the
Subordinated Deferrable Interest Debentures may be issued from time to time in
one or more series. The Subordinated Deferrable Interest Debentures are issuable
in one or more series pursuant to an indenture supplemental to the Subordinated
Debentures Indenture or a resolution of the Company's Board of Directors or a
special committee thereof (each, a "Supplemental Subordinated Debentures
Indenture").
 
                                       26

    In the event Subordinated Deferrable Interest Debentures are issued to a
Trust or a trustee of such Trust in connection with the issuance of Trust
Securities by such Trust, such Subordinated Deferrable Interest Debentures
subsequently may be distributed pro rata to the holders of such Trust Securities
in connection with the termination of such Trust upon the occurrence of certain
events described in the Prospectus Supplement relating to such Trust Securities.
Only one series of Subordinated Deferrable Interest Debentures will be issued to
a Trust or a trustee of such Trust in connection with the issuance of Trust
Securities by such Trust.
 
    Reference is made to the accompanying Prospectus Supplement for the
following terms of the series of Subordinated Deferrable Interest Debentures
being offered thereby: (i) the specific title of such Subordinated Deferrable
Interest Debentures; (ii) any limit on the aggregate principal amount of such
Subordinated Deferrable Interest Debentures; (iii) the date or dates on which
the principal of such Subordinated Deferrable Interest Debentures is payable and
the right, if any, to extend such date or dates; (iv) the rate or rates at which
such Subordinated Deferrable Interest Debentures will bear interest or the
method of determination of such rate or rates; (v) the date or dates from which
such interest shall accrue, the interest payment dates on which such interest
will be payable or the manner of determination of such interest payment dates
and the record dates for the determination of holders to whom interest is
payable on any such interest payment dates; (vi) the right, if any, to extend
the interest payment periods and the duration of such extension; (vii) the
period or periods within which, the price or prices at which, and the terms and
conditions upon which, such Subordinated Deferrable Interest Debentures may be
redeemed, in whole or in part, at the option of the Company; (viii) the right
and/or obligation, if any, of the Company to redeem or purchase such
Subordinated Deferrable Interest Debentures pursuant to any sinking fund or
analogous provisions or at the option of the holder thereof and the period or
periods during which, the price or prices at which, and the terms and conditions
upon which, such Subordinated Deferrable Interest Debentures shall be redeemed
or purchased, in whole or part, pursuant to such right and/or obligation; (ix)
the terms of subordination; (x) if other than denominations of $25 or any
integral multiple thereof, the denominations in which such Subordinated
Deferrable Interest Debentures shall be issuable; (xi) any and all other terms
with respect to such series; and (xii) whether such Subordinated Deferrable
Interest Debentures are issuable as a global security, and in such case, the
identity of the depository.
 
    The Subordinated Debentures Indenture does not contain any provisions that
afford holders of Subordinated Deferrable Interest Debentures protection in the
event of a highly leveraged transaction involving the Company.
 
SUBORDINATION
 
    The Subordinated Deferrable Interest Debentures will be subordinated and
junior in right of payment to certain other indebtedness of the Company to the
extent set forth in the accompanying Prospectus Supplement.
 
CERTAIN COVENANTS
 
    If Subordinated Deferrable Interest Debentures are issued to a Trust or a
trustee of such Trust in connection with the issuance of Trust Securities by
such Trust and (i) there shall have occurred and be continuing any event that
would constitute an Event of Default under the Subordinated Debentures Indenture
or (ii) the Company shall be in default with respect to its payment of any
obligations under the related Trust Preferred Securities Guarantee or Trust
Common Securities Guarantee, and such default shall be continuing, then (a) the
Company shall not declare or pay any dividend on, make any distributions with
respect to, or redeem, purchase or make a liquidation payment with respect to,
any of its capital stock, (b) the Company shall not make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities issued by the Company which rank PARI PASSU with or junior to
such Subordinated Deferrable Interest Debentures and (c) the Company shall not
make any guarantee payments (other than pursuant to the Trust Preferred Security
Guarantees) with respect to the foregoing.
 
                                       27

    If Subordinated Deferrable Interest Debentures are issued to a Trust or a
trustee of such Trust in connection with the issuance of Trust Securities by
such Trust and the Company shall have given notice of its election to defer
payments of interest on such Subordinated Deferrable Interest Debentures by
extending the interest payment period as provided in the Subordinated Debentures
Indenture and such period, or any extension thereof, shall be continuing, then
(a) the Company shall not declare or pay any dividend on, make any distributions
with respect to, or redeem, purchase or make a liquidation payment with respect
to, any of its capital stock, (b) the Company shall not make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities issued by the Company which rank PARI PASSU with or junior to
such Subordinated Deferrable Interest Debentures and (c) the Company shall not
make any guarantee payments (other than pursuant to the Trust Preferred Security
Guarantees) with respect to the foregoing.
 
    Notwithstanding the foregoing restrictions, the Company will be permitted,
in any event, to make dividend, redemption, liquidation and guarantee payments
on capital stock, and interest, principal, redemption and guarantee payments on
debt securities issued by the Company ranking PARI PASSU with or junior to
Subordinated Deferrable Interest Debentures, where the payment is made by way of
securities (including capital stock) that rank junior to the securities on which
such payment is being made.
 
    In the event Subordinated Deferrable Interest Debentures are issued to a
Trust or a trustee of such Trust in connection with the issuance of Trust
Securities of such Trust, for so long as such Trust Securities remain
outstanding, the Company will covenant (i) to directly or indirectly maintain
100% ownership of the Trust Common Securities of such Trust; PROVIDED, HOWEVER,
that any permitted successor of the Company under the Subordinated Debentures
Indenture may succeed to the Company's ownership of such Trust Common
Securities, (ii) not to cause, as sponsor of such Trust, or to permit, as holder
of the Trust Common Securities of such Trust, the termination, dissolution or
winding-up of such Trust, except in connection with a distribution of the
Subordinated Deferrable Interest Debentures as provided in the Declaration and
in connection with certain mergers, consolidations or amalgamations, (iii) to
use its reasonable efforts to cause such Trust (a) to remain a statutory
business trust, except in connection with the distribution of Subordinated
Deferrable Interest Debentures to the holders of Trust Securities in liquidation
of such Trust, the redemption of all of the Trust Securities of such Trust, or
certain mergers, consolidations or amalgamations, each as permitted by the
Declaration of such Trust, and (b) to otherwise continue not to be classified as
an association taxable as a corporation or partnership for United States federal
income tax purposes and (iv) to use reasonable efforts to cause each holder of
Trust Securities of such Trust to be treated as owning an undivided beneficial
interest in the Subordinated Deferrable Interest Debentures issued to such
Trust.
 
FORM, EXCHANGE, REGISTRATION AND TRANSFER
 
    Subordinated Deferrable Interest Debentures of each series will be issued in
registered form and in either certificated form or represented by one or more
global securities. If not represented by one or more global securities,
Subordinated Deferrable Interest Debentures may be presented for registration or
transfer (with the form of transfer endorsed thereon duly executed) or exchange
at the office of the registrar for the Subordinated Deferrable Interest
Debentures or at the office of any transfer agent designated by the Company for
such purpose with respect to any series of Subordinated Deferrable Interest
Debentures and referred to in an applicable Prospectus Supplement, without
service charge and upon payment of any taxes and other governmental charges as
described in the Subordinated Debentures Indenture. Such transfer or exchange
will be effected upon the registrar for the Subordinated Deferrable Interest
Debentures or such transfer agent, as the case may be, being satisfied with the
documents of title and identity of the person making the request. The Company
will appoint the Subordinated Debentures Trustee as registrar with respect to
each series of Subordinated Deferrable Interest Debentures. If a Prospectus
Supplement refers to any transfer agents (in addition to the Subordinated
Debentures Registrar) initially designated by the Company with respect to any
series of Subordinated Deferrable Interest Debentures, the Company may at any
time rescind the designation of any such transfer agent or
 
                                       28

approve a change in the location through which any such transfer agent acts,
except that the Company will be required to maintain a transfer agent in each
place of payment for such series. The Company may at any time designate
additional transfer agents with respect to any series of Subordinated Deferrable
Interest Debentures.
 
    In the event of any redemption in part, the Company shall not be required to
(i) issue, register the transfer of or exchange any Subordinated Deferrable
Interest Debentures during a period beginning at the opening of business 15 days
before any selection for redemption of Subordinated Deferrable Interest
Debentures of like tenor and of the series of which such Subordinated Deferrable
Interest Debentures are a part, and ending at the close of business on the
earliest date on which the relevant notice of redemption is deemed to have been
given to all holders of Subordinated Deferrable Interest Debentures of like
tenor and of such series to be redeemed and (ii) register the transfer of or
exchange any Subordinated Deferrable Interest Debentures so selected for
redemption, in whole or in part, except the unredeemed portion of any
Subordinated Deferrable Interest Debentures being redeemed in part.
 
PAYMENT AND PAYING AGENTS
 
    Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of and premium, if any, on any Subordinated Deferrable Interest
Debentures will be made only against surrender to the Paying Agent of such
Subordinated Deferrable Interest Debentures. Unless otherwise indicated in an
applicable Prospectus Supplement, principal of, premium, if any, and interest,
if any, on Subordinated Deferrable Interest Debentures will be payable, subject
to any applicable laws and regulations, at the office of such Paying Agent or
Paying Agents as the Company may designate from time to time, except that at the
option of the Company, payment of any interest may be made by check mailed to
the address of the person entitled thereto as such address shall appear in the
register with respect to such Subordinated Deferrable Interest Debentures.
Unless otherwise indicated in an applicable Prospectus Supplement, payment of
interest on a Subordinated Deferrable Interest Debenture on any Interest Payment
Date will be made to the person in whose name such Subordinated Deferrable
Interest Debenture (or predecessor security) is registered at the close of
business on the date described in the applicable Prospectus Supplement for such
interest payment.
 
    The Subordinated Debentures Trustee will act as Paying Agent with respect to
each series of Subordinated Deferrable Interest Debentures. The Company may at
any time designate additional Paying Agents or rescind the designation of any
Paying Agents or approve a change in the office through which any Paying Agent
acts, except that the Company will be required to maintain a Paying Agent in
each place of payment for each series of Subordinated Deferrable Interest
Debentures.
 
    All moneys paid by the Company to a Paying Agent for the payment of the
principal of or premium or interest, if any, on any Subordinated Deferrable
Interest Debentures of any series which remain unclaimed at the end of two years
after such principal or premium or interest, if any, shall have become due and
payable will be repaid to the Company and the holder of such Subordinated
Deferrable Interest Debentures will thereafter look only to the Company for
payment thereof.
 
GLOBAL SECURITIES
 
    If any Subordinated Deferrable Interest Debentures of a series are
represented by one or more global securities (each, a "Global Security"), the
applicable Prospectus Supplement will describe the circumstances, if any, under
which beneficial owners of interests in any such Global Security may exchange
such interests for Subordinated Deferrable Interest Debentures of such series
and of like tenor and principal amount in any authorized form and denomination.
Principal of and any premium, if any, and interest on a Global Security will be
payable in the manner described in the applicable Prospectus Supplement.
 
    The specific terms of the depositary arrangement with respect to any portion
of a series of Subordinated Deferrable Interest Debentures to be represented by
a Global Security will be described in the applicable Prospectus Supplement.
Reference is made to "Description of Debt Securities--Registered
 
                                       29

Global Securities" for a description of provisions the Company anticipates will
apply to all depositary arrangements, including those relating to Subordinated
Deferrable Interest Debentures.
 
MODIFICATION OF THE SUBORDINATED DEBENTURES INDENTURE
 
    The Subordinated Debentures Indenture contains provisions permitting the
Company and the Subordinated Debentures Trustee, with the consent of the holders
of not less than a majority in principal amount of the Subordinated Deferrable
Interest Debentures of each series which are affected by the modification, to
modify the Subordinated Debentures Indenture or any supplemental indenture
affecting that series or the rights of the holders of that series of
Subordinated Deferrable Interest Debentures; PROVIDED, HOWEVER, that no such
modification may, without the consent of the holder of each outstanding
Subordinated Deferrable Interest Debenture affected thereby, (i) extend the
fixed maturity of any Subordinated Deferrable Interest Debentures of any series,
or reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof, without the consent of the holder of each Subordinated Deferrable
Interest Debenture so affected or (ii) reduce the percentage of Subordinated
Deferrable Interest Debentures the holders of which are required to consent to
any such supplemental indenture, without the consent of the holders of each then
outstanding Subordinated Deferrable Interest Debenture affected thereby.
 
    In addition, the Company and the Subordinated Debentures Trustee may
execute, without the consent of any holder of Subordinated Deferrable Interest
Debentures, any supplemental indenture for certain other usual purposes
including the creation of any new series of Subordinated Deferrable Interest
Debentures.
 
EVENTS OF DEFAULT
 
    With respect to a particular series of Subordinated Deferrable Interest
Debentures, the Subordinated Debentures Indenture provides (or the Supplemental
Subordinated Debentures Indenture for such series will provide) that any one or
more of the following described events which has occurred and is continuing
constitutes an "Event of Default" with respect to such series of Subordinated
Deferrable Interest Debentures.
 
        (a) failure for 30 days to pay interest on the Subordinated Deferrable
    Interest Debentures of that series, including any Additional Interest in
    respect thereof, when due; PROVIDED, HOWEVER, that a valid extension of the
    interest payment period by the Company shall not constitute a default in the
    payment of interest for this purpose; or
 
        (b) failure to pay principal or premium, if any, on the Subordinated
    Deferrable Interest Debentures of that series when due whether at maturity,
    upon redemption, by declaration or otherwise, or to make any sinking fund
    payment with respect to that series; or
 
        (c) failure to observe or perform any other covenant (other than those
    specifically relating to another series) contained in the Subordinated
    Debentures Indenture for 90 days after written notice to the Company from
    the Subordinated Debentures Trustee or the holders of at least 25% in
    principal amount of the outstanding Subordinated Deferrable Interest
    Debentures of that series; or
 
        (d) certain events of bankruptcy, insolvency or reorganization of the
    Company; or
 
        (e) in the event Subordinated Deferrable Interest Debentures are issued
    to a Trust or a trustee of such Trust in connection with the issuance of
    Trust Securities by such Trust, the voluntary or involuntary dissolution,
    winding-up or termination of such Trust, except in connection with the
    distribution of Subordinated Deferrable Interest Debentures to the holders
    of Trust Securities in liquidation of such Trust, the redemption of all of
    the Trust Securities of such Trust, or certain mergers, consolidations or
    amalgamations, each as permitted by the Declaration of such Trust.
 
    The holders of a majority in aggregate outstanding amount of any series of
Subordinated Deferrable Interest Debentures have the right to direct the time,
method and place of conducting any proceeding for
 
                                       30

any remedy available to the Subordinated Debentures Trustee for the series. The
Subordinated Debentures Trustee or the holders of not less than 25% in aggregate
outstanding principal amount of any particular series of the Subordinated
Deferrable Interest Debentures may declare the principal immediately due and
payable upon an Event of Default with respect to such series, but the holders of
a majority in aggregate outstanding principal amount of such series may annul
such declaration and waive the default with respect to such series if the Event
of Default has been cured and a sum sufficient to pay all matured installments
of interest and principal due otherwise than by acceleration and any applicable
premium has been deposited with the Subordinated Debentures Trustee. If an Event
of Default results from the failure of the Company to pay when due principal of
or interest on the Subordinated Deferrable Interest Debentures issued to a
Trust, during the continuance of such an Event of Default a holder of Trust
Preferred Securities issued by such Trust may immediately institute a legal
proceeding directly against the Company to obtain payment of such principal or
interest on Subordinated Deferrable Interest Debentures having a principal
amount equal to the aggregate liquidation amount of the Trust Preferred
Securities owned of record by such holder.
 
    The holders of a majority in aggregate outstanding principal amount of any
series of Subordinated Deferrable Interest Debentures affected thereby may, on
behalf of the holders of all the Subordinated Deferrable Interest Debentures of
such series, waive any past default except (i) a default in the payment of
principal, premium, if any, or interest (unless such default has been cured and
a sum sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration and any applicable premium has been deposited
with the Subordinated Debentures Trustee) or (ii) a default in the covenants
described in the first or second paragraph under "--Certain Covenants" above.
 
CONSOLIDATION, MERGER AND SALE
 
    The Subordinated Debentures Indenture does not contain any covenant which
restricts the ability of the Company to merge or consolidate with or into any
other corporation, sell or convey all or substantially all of its assets to any
person, firm or corporation or otherwise engage in restructuring transactions.
 
MANDATORY DISPOSITION PURSUANT TO GAMING LAWS
 
    The Subordinated Debentures Indenture will provide that each holder and
beneficial owner of Subordinated Deferrable Interest Debentures, by accepting or
otherwise acquiring an interest in the Subordinated Deferrable Interest
Debentures, shall be deemed to have agreed that if the Gaming Authority of any
jurisdiction in which the Company or any of its subsidiaries (or any joint
venture in which the Company or a subsidiary of the Company is a participant)
now or hereafter conducts or proposes to conduct gaming requires that a person
who is a holder or beneficial owner of Subordinated Deferrable Interest
Debentures must be licensed, qualified or found suitable, or comply with any
other requirement under applicable Gaming Laws, such holder or beneficial owner
shall apply for a license, qualification or a finding of suitability or comply
with such other requirement, as the case may be, within the prescribed time
period. If such holder or beneficial owner fails to apply to be, or fails to
become, licensed or qualified, is found unsuitable or fails to comply with any
other requirement, as the case may be (a "failure of compliance"), then the
Company shall have the right, at its option (i) to require such person to
dispose of its Subordinated Deferrable Interest Debentures or beneficial
interest therein within 30 days of receipt of notice of the Company's election
or such earlier date as may be requested or prescribed by the Gaming Authority
or (ii) to redeem such Subordinated Deferrable Interest Debentures (which
redemption may be less than 30 days following the notice of redemption if so
requested or prescribed by the Gaming Authority) at a redemption price equal to
the lesser of (A) such person's cost, (B) 100% of the principal amount thereof,
plus accrued and unpaid interest to the earlier of the redemption date and the
date of any failure of compliance, or (C) such other amount as may be required
by applicable law or by order of any Gaming Authority. The Company shall notify
the Trustee in writing of any such redemption as soon as practicable. The
Company shall not be responsible for any costs or expenses any such holder or

INFORMATION CONCERNING THE SUBORDINATED DEBENTURES TRUSTEE
 
    The Subordinated Debentures Trustee, prior to default, undertakes to perform
only such duties as are specifically set forth in the Subordinated Debentures
Indenture and, after default, shall exercise the same degree of care as a
prudent individual would exercise in the conduct of his or her own affairs.

obligation to exercise any of the powers vested in it by the Subordinated
Debentures Indenture at the request of any holder of Subordinated Deferrable
Interest Debentures, unless offered reasonable indemnity by such holder against
the costs, expenses and liabilities which might be incurred thereby. The
Subordinated Debentures Trustee is not required to expend or risk its own funds
or otherwise incur personal financial liability in the performance of its duties
if the Subordinated Debentures Trustee reasonably believes that repayment or
adequate indemnity is not reasonably assured to it.
 
    The Subordinated Debentures Trustee serves as trustee under other indentures
pursuant to which unsecured debt securities of the Company are outstanding.
 
MISCELLANEOUS
 
    The Company will have the right at all times to assign any of its rights or
obligations under the Subordinated Debentures Indenture to a direct or indirect
wholly-owned subsidiary of the Company; PROVIDED, HOWEVER, that in the event of
any such assignment, the Company will remain liable for all of its obligations
thereunder. Subject to the foregoing, the Subordinated Debentures Indenture will
be binding upon and inure to the benefit of the parties thereto and their
respective successors and assigns. The Subordinated Debentures Indenture
provides that it may not otherwise be assigned by the parties thereto.

    The Company or a Trust may offer and sell the Securities directly to
purchasers or to or through underwriters, dealers or agents. Any such
underwriter, dealer or agent involved in the offer and sale of the Securities in
respect of which this Prospectus is delivered will be named in the applicable
Prospectus Supplement. The applicable Prospectus Supplement with respect to such
Securities will also set forth the terms of the offering of such Securities,
including the purchase price of such Securities and the proceeds to the Company
or the applicable Trust from such sale, any underwriting discounts and other
items constituting underwriters' compensation, any initial public offering price
and any discounts or concessions allowed or reallowed or paid to dealers and any
securities exchanges on which such Securities may be listed.

or more transactions at a fixed price or prices, which may be changed, or from
time to time at market prices prevailing at the time of sale, at prices related
to such prevailing market prices or at negotiated prices. The applicable
Prospectus Supplement will describe the method of distribution of the
Securities.
 
    If underwriters are used in an offering of Securities, the name of each
managing underwriter, if any, and any other underwriters and terms of the
transaction, including any underwriting discounts and other items constituting
compensation of the underwriters and dealers, if any, will be set forth in the
applicable Prospectus Supplement relating to such offering and the Securities
will be acquired by the underwriters for their own accounts and may be resold
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale. Any initial public offering price and any discounts or
concessions allowed or reallowed or paid to dealers may be changed from time to
time. Underwriters, dealers and agents may be entitled, under agreements which
may be entered into with the Company, to indemnification against and
contribution toward certain civil liabilities, including liabilities under the
Securities Act, and to reimbursement by the Company of certain expenses.
 
    If a dealer is used in an offering of Securities, the Company will sell such
Securities to the dealer, as principal. The dealer may then resell such
Securities to the public at varying prices to be determined by such dealer at
the time of resale. The name of the dealer and the terms of the transaction will
be set forth in the applicable Prospectus Supplement relating thereto.
 
    If an agent is used in an offering of Securities, the agent will be named,
and the terms of the agency will be set forth, in the applicable Prospectus
Supplement relating thereto. Unless otherwise indicated in such applicable
Prospectus Supplement, an agent will act on a best efforts basis for the period
of its appointment.
 
    Dealers and agents named in an applicable Prospectus Supplement may be
deemed to be underwriters (within the meaning of the Securities Act) of the
Securities described therein and, under agreements which may be entered into
with the Company and/or an applicable Trust, may be entitled to indemnification
by the Company and/or an applicable Trust against certain civil liabilities
under the Securities Act. Underwriters, dealers and agents may be customers of,

applicable Trust in the ordinary course of business.

the applicable Trust pursuant to contracts providing for payment and delivery at
a future date. Institutional investors with which such contracts may be made

purchasers must be approved by the Company or the applicable Trust. The
obligations of any purchaser under any such contract will not be subject to any
conditions except that (i) the purchase of the Securities shall not at the time
of delivery be prohibited under the laws of any jurisdiction to which such
purchaser is subject and (ii) if the Securities are also being sold to
underwriters, the Company or the applicable Trust shall have sold to such
underwriters the Securities not subject to delayed delivery. Underwriters and
other agents will not have any responsibility in respect of the validity or
performance of such contracts.
 
    In addition, the Securities may be offered and sold by the holders thereof
in one or more of the transactions described above, which transactions may be

participating therewith may be deemed to be underwriters within the meaning of
Section 2(11) of the Securities Act, and any commissions, discounts or
concessions upon such sale, or any profit on the resale of such Securities,
received thereby in connection with such sale may be deemed to be underwriting
commissions or discounts under the Securities Act. The compensation, including
commissions, discounts. concessions and other profits, received by any broker,
dealer or underwriter in connection with the sale of any of such Securities may
be less than or in excess of customary commissions.

applicable Prospectus Supplement relating to each offering.
 
    The Securities may or may not be listed on a national securities exchange or
a foreign securities exchange. No assurances can be given that there will be a

                                                                    ---------

 
ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 78.751 of the general corporation law of Nevada (the "Nevada Law")
permits a corporation to indemnity any of its directors, officers, employees and
agents against costs and expenses arising from claims, suits and proceedings if
such person acted in good faith and in a manner reasonably believed to be in or
not opposed to the best interests of the corporation. No indemnification may be
made in respect of claims as to which such person is found liable for negligence
or misconduct in the performance of his duty to the corporation unless the court
determines that, notwithstanding the determination of liability, indemnification
would be appropriate. The indemnification provisions of the Nevada Law expressly
do not exclude any other rights a person may have to indemnification under any
bylaw, among other things.
 
    Article X, Section 10.2 of the Company's Restated Bylaws provides for
mandatory indemnification of directors and officers to the fullest extent now or
hereafter permitted by law.
 
    The Company maintains a liability insurance policy under which officers and
directors are generally indemnified against losses and liability (including
costs, expenses, settlements and judgments) incurred by them in such capacities,
individually or otherwise, other than specified excluded losses. The insurance
policy will pay on behalf of the Company all covered losses for which the
Company grants indemnification of each officer or director as permitted by law
which the officer or director becomes legally obligated to pay on account of an
indemnifiable claim. The policy would generally cover, in addition to other
liabilities, liabilities arising under the federal securities laws; however, the
subject of loss may not include any claim or claims arising out of or as a
result of the filing of a registration statement under the Securities Act or any
liability under Section 16(b) of the Securities Exchange Act of 1934.
 
    The respective Declarations of Circus Finance I and Circus Finance II (each
a "Trust"), and the respective forms of Amended and Restated Declaration of the
Trusts filed as exhibits to this Registration Statement, each provides that to
the fullest extent permitted by applicable law, the Company shall indemnify and
hold harmless each of such Trust's trustees and each of the officers, directors
and affiliates of each such Trustee (each an "Indemnified Person") from and
against any loss, damage or claim incurred by such Indemnified Person in good
faith on behalf of such Trust and in a manner such Indemnified Person reasonably
believed to be within the scope of authority conferred on such Indemnified
Person by the Declaration except that no Indemnified Person shall be entitled to
be indemnified in respect of any loss, damage or claim incurred by such
Indemnified Person by reason of gross negligence or willful misconduct with
respect to such acts or omissions. Each such Declaration also provides that, to
the fullest extent permitted by applicable law, expenses (including legal fees)
incurred by an Indemnified Person in defending any claim, demand, action, suit
or proceeding shall, from time to time, be advanced by the Company prior to the
final disposition of such claim, demand, action, suit or proceeding upon receipt
by
 
                                      II-1

the Company of an undertaking by or on behalf of the Indemnified Person to repay
such amount if it shall be determined that the Indemnified Person is not
entitled to be indemnified as authorized in the Declaration.

ITEM 17. UNDERTAKINGS
 
    (a) The undersigned Registrants hereby undertake:
 
        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:
 
            (i) To include any prospectus required by section 10(a)(3) of the
       Securities Act of 1933;
 
            (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement. 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 registration statement is on Form S-3, Form S-8 or Form F-3, and 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 the 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) That, for purposes of determining any liability under the Securities Act
of 1933, each filing of the Registrant's annual report pursuant to Section 13(a)
or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
    (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the provision describing in Item 15 above, or
otherwise, the Registrant has 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 the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the 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 of whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
                                      II-6
