                                  THE COMPANY
 
    Mirage Resorts, Incorporated (the "Company") owns and operates some of the
most successful casino-based entertainment resorts in the world. These resorts
include (i) The Mirage, a hotel-casino and destination resort on the Las Vegas
Strip, (ii) Treasure Island at The Mirage ("Treasure Island"), a hotel-casino
resort adjacent to The Mirage, (iii) the Golden Nugget, a hotel-casino in
downtown Las Vegas, and (iv) the Golden Nugget-Laughlin, a hotel-casino in
Laughlin, Nevada. The Company also owns a 50% interest in a joint venture which
owns and operates the Monte Carlo Resort & Casino ("Monte Carlo"), a
hotel-casino resort on the Las Vegas Strip which opened on June 21, 1996. The
Company is currently constructing Bellagio, an elegant hotel-casino and
destination resort on the Las Vegas Strip, and Beau Rivage, a luxurious
hotel-casino and beachfront resort in Biloxi, Mississippi. When these properties
are opened, the total number of hotel rooms at the Company's wholly owned
properties will increase by approximately 59% and total casino square footage at
such facilities will increase by approximately 92%.
 
    The Company's philosophy is to build superior products in each of its
markets and to maintain these products in first-class condition. The Company
also believes that its progressive human resource policies have resulted in
superior customer service and low staff turnover. This philosophy has produced
high and stable levels of profitability at each of its major resorts.
 
    Unless the context otherwise requires, references to the Company include the
Company and its wholly owned subsidiaries, through which its operations are
conducted.
 
THE MIRAGE
 
    The Mirage is a luxurious, tropically themed destination resort containing
approximately 3.1 million square feet in a 29-story Y-shaped hotel tower and an

    During 1995, all of the standard guest rooms and 61 of the suites were
extensively refurbished and enhanced. The exterior of the resort is landscaped
with palm trees, abundant foliage and more than four acres of lagoons and other
water features centered around a 54-foot simulated volcano and waterfall. Each
evening, the volcano erupts at regular intervals, spectacularly illuminating the
front of the resort. Inside the front entrance is an atrium with a tropical
garden and additional water features capped by a 100-foot-high glass dome. The
atrium has an advanced environmental control system and creative lighting and
other special effects designed to replicate the sights, sounds and fragrances of
the South Seas. Located at the rear of the hotel, adjacent to the swimming pool
area, is a dolphin habitat housing seven Atlantic bottlenose dolphins.
 
    As of October 1, 1996, The Mirage's casino offered 119 table games
(including blackjack, craps, roulette, baccarat, mini-baccarat, let it ride, pai
gow, pai gow poker, Caribbean stud poker and big six), keno, poker, a race and
sports book and approximately 2,245 slot machines or similar coin-operated

CURRENT EXPANSION PROJECTS
 
    BELLAGIO
 
    The Company is constructing Bellagio on approximately 120 acres on the Las
Vegas Strip between Flamingo Road and Tropicana Avenue. Bellagio is designed to
be the Company's most ambitious and elegant destination resort and will include
a 34-story hotel tower with approximately 3,000 lavishly appointed guest rooms
(including 361 suites and villas) and a 152,000-square foot casino, overlooking
a lake inspired by Lake Como in Northern Italy. Several times each day the
lake's fountains will come alive in a choreographed ballet of water, music and
lights. Bellagio will feature a wide variety of casual and gourmet restaurants
in both indoor and outdoor settings, upscale retail boutiques and extensive
meeting, convention and banquet space. Cirque du Soleil will perform an all-new
production in a specially designed showroom. The resort will be lushly
landscaped with classical gardens and European fountains and pools. Bellagio is
currently expected to cost approximately $1.35 billion (including land and
capitalized interest) and is scheduled to open in the summer of 1998.
 
    BEAU RIVAGE
 
    In July 1996, the Company began construction of Beau Rivage, a luxurious
beachfront resort in Biloxi, Mississippi. Beau Rivage will be situated on a
21-acre site where Interstate 110 meets the Gulf Coast. The resort will feature
a 75,000-square foot casino, 1,804 hotel rooms (including 87 suites), a variety
of restaurants and retail outlets, a 1,200-seat showroom, approximately 32,000
square feet of meeting and banquet space, a health spa, a beauty salon, a
swimming pool and a multi-story parking garage. Beau Rivage is scheduled for
completion in the first quarter of 1998 at a total cost, including land and
capitalized interest, of approximately $500 million.
 
    As with any major construction project, the Bellagio and Beau Rivage
projects involve many risks, including 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 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 their design and features. It is possible that the existing
budget and construction plans for either project may be changed for competitive
or other reasons. Accordingly, there can be no assurance that either project
will be completed within the time periods or budgets which are currently
contemplated.
 
FUTURE EXPANSION
 
    ATLANTIC CITY
 
    The Company and the City of Atlantic City have entered into a redevelopment
agreement providing for the City to convey 150 acres located in the Marina area
of Atlantic City to the Company in exchange for the Company agreeing to develop
a casino-based destination resort on the site and undertaking certain other
obligations, including remediation of environmental contamination and the
relocation of City-owned facilities currently located on the site. Closing under
the redevelopment agreement requires the satisfaction of a number of conditions,
including the receipt by the Company of all requisite licenses, permits,
allocations and authorizations, resolution of real estate title issues and the
execution by the Company and the New Jersey Department of Transportation of a
definitive agreement with respect to the construction and financing of certain
major roadway improvements designed to improve access to the Marina area.
Accordingly, there can be no assurance as to whether or when the Company will
proceed with the project.
 
                                      S-4
<PAGE>
    As currently proposed, the project, if developed, would include the
Company's construction of a wholly owned luxury hotel-casino resort featuring
approximately 2,000 guest rooms, a 115,000-square foot casino, a variety of
restaurants, a large entertainment and retail concourse and other amenities.
Although such resort has not yet been designed, the Company estimates that it
will cost between $700 million and $1 billion and require 24 to 30 months to
complete. The Company does not expect to commence construction prior to late
1997. The Company, which intends to act as master developer of the entire site,
has entered into separate agreements with Boyd Gaming Corporation ("BGC") and
Circus pursuant to which the Company and BGC will, through a joint venture,
construct a hotel-casino resort containing a minimum of 1,000 guest rooms on a
portion of the site and Circus will acquire a portion of the site from the
Company and construct an additional 2,000-room hotel-casino resort, each in an
architectural format that conforms to an agreed-to master plan. Development of
the projects by the joint venture and Circus is also contingent upon the
satisfaction of the conditions to the Company's obligation to develop its wholly
owned resort.
 
    OTHER
 
    The Company regularly evaluates and pursues potential expansion and
acquisition opportunities in both the domestic and international markets. Such
opportunities may include the ownership, management and operation of gaming and
other entertainment facilities in states other than Nevada or outside of the
United States, either alone or with joint venture partners. Development and
operation of any gaming facility in a new jurisdiction are subject to numerous
contingencies, several of which are outside of the Company's control and may
include the enactment of appropriate gaming legislation, the issuance of
requisite permits, licenses and approvals, the availability of appropriate
financing and the satisfaction of other conditions. There can be no assurance
that the Company will elect or be able to consummate any such acquisition or
expansion opportunity. In the past year, the Company has reduced its expansion
efforts in emerging gaming jurisdictions in order to concentrate on the design
and development of Bellagio and Beau Rivage and its potential project in
Atlantic City.
 
    The following table sets forth certain data, as of October 1, 1996,
regarding the Company's major resorts and certain estimates regarding the
Company's two projects under construction.

licensed gaming operations are currently conducted, and Mississippi, where the
Company and its subsidiary which is constructing and will operate Beau Rivage
are licensed, and other states, where the Company may conduct gaming operations
in the future (including New Jersey), 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 Nevada Gaming
Commission, as well as the Mississippi Gaming Commission and the New Jersey
Casino Control Commission (individually, a "Gaming Authority" and collectively,
the "Gaming Authorities"), may, among other things, limit, condition, suspend or
revoke a Gaming License or approval to own the stock or joint venture interest
of any of the Company's licensed Nevada or Mississippi operations or any
operations subsequently conducted in New Jersey, 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 persons involved. The suspension or
revocation of any of the Company's Gaming Licenses or levy on the Company 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 Nevada and Mississippi as
well as 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 may, in its discretion, require the holder or
beneficial owner of any debt security issued by the Company to file
applications, be investigated and be found suitable to own such debt security if
the Nevada Gaming Commission has reason to believe that such holder's or
beneficial owner's acquisition of such debt security would be inconsistent with
the declared policy of the State of Nevada. If the Nevada Gaming Commission
determines that a person is unsuitable to own such debt security, then pursuant
to the Nevada Gaming Control Act, the Company can be sanctioned, including the
loss of its approvals, if without the prior approval of the Nevada Gaming
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 or similar transaction. The
Mississippi Gaming Commission has similar jurisdiction over the holders and
beneficial owners of debt securities issued by the Company and may also require
their investigation and approval, and the New Jersey Casino Control Commission
will have such jurisdiction and authority if the Company is subsequently
licensed to conduct gaming operations in that state.
 
    Under Nevada and Mississippi law, 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 23, 1996, the Nevada Gaming Commission granted the Company prior approval to
make public offerings for a period of one year, subject to certain conditions
(the "Shelf Approval"). However, the 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 and must be renewed
annually. The Shelf Approval does not constitute a finding, recommendation or
approval by the Nevada Gaming Commission or the Nevada State Gaming Control
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 public offering of the Notes
will be made pursuant to the Shelf Approval. The
 
                                      S-6
<PAGE>
Company received a similar one-year waiver of approval requirements from the
Mississippi Gaming Commission on June 20, 1996.
 
    Consistent with the foregoing, the Indenture governing the Notes will
provide that each holder and beneficial owner thereof, by accepting any of the
Notes, shall be deemed to have agreed that if the Gaming Authority of any
jurisdiction in which the Company or any of its subsidiaries conducts or
proposes to conduct gaming requires that a person who is a holder or beneficial
owner must be licensed, qualified or found suitable under applicable Gaming
Laws, such holder or beneficial owner shall apply for a license, qualification
or finding of suitability within the required time period. If such person fails
to apply or become licensed or qualified or is not found suitable (in each case,
a "failure of compliance"), the Company shall have the right, at its option, (i)
to require such person to dispose of its Notes 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 such Gaming Authority or (ii) to
redeem such Notes at a redemption price equal to the lesser of (A) such person's
cost or (B) 100% of the principal amount thereof, plus, in either case, accrued
and unpaid interest to the earlier of the redemption date or the date of the
failure of compliance, which may be less than 30 days following the notice of
redemption if so requested or prescribed by the Gaming Authority. The Company
shall notify the Trustee under the Indenture 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 finding of suitability.
 
    For additional information regarding the regulation of the Company's gaming
operations, see the discussion under the caption "Regulation and Licensing" in
Item 1 of the Company's Annual Report on Form 10-K for the year ended December
31, 1995, incorporated by reference in the accompanying Prospectus.
 
                                USE OF PROCEEDS
 
    The net proceeds to be received by the Company from the sale of the Notes,
estimated at $247.5 million, are expected to be used to repay borrowings under
the Company's revolving bank credit facility and for other general corporate
purposes, which may include the development and construction of Bellagio and
Beau Rivage as well as any new hotel, casino and resort facilities developed in
Atlantic City. As of September 30, 1996, the Company had outstanding
indebtedness under its revolving bank credit facility of $113.0 million, bearing
interest at a weighted average rate of approximately 5.76% per annum. The
amounts outstanding under the revolving bank credit facility are short-term with
various maturities.
 
    Pending utilization of the net proceeds as set forth above, such proceeds
may be invested in government securities, short-term commercial paper or
repurchase agreements, certificates of deposit, corporate obligations or other
marketable securities.

                            RECENT OPERATING RESULTS
 
    The Company reported 1996 third quarter net income of $48.7 million, or
$0.25 per share, an 8% increase over the $45.2 million, or $0.23 per share,
reported in the third quarter of 1995. This was the Company's eleventh
consecutive quarter in which earnings per share exceeded the prior-year results.
Revenues, net of promotional allowances, totaled $338.6 million, an increase of
$3.4 million over the $335.2 million reported in the 1995 third quarter.
Operating income grew by 4% to $76.0 million, versus $73.1 million in the
prior-year quarter.
 
    Monte Carlo's first full quarter of operations produced operating income of
$18.6 million on net revenues of $67.5 million. Net of the unconsolidated
subsidiary's interest expense, the facility contributed $7.2 million to the
Company's pretax income. Monte Carlo operated at over 98% occupancy in the
quarter, with an average standard room rate of nearly $70.
 
    Net non-casino revenues at The Mirage rose 10% over the prior-year quarter.
Casino revenues excluding baccarat were approximately flat, but the level of
baccarat activity declined from the prior-year quarter. As a result, operating
income at The Mirage declined by 14% in the quarter. For the nine-month period,
the property's operating income increased 2% over the prior-year corresponding
period.
 
    Net revenues at Treasure Island increased 4% over the prior-year quarter
despite the new competition from Monte Carlo and Stratosphere. Operating income
increased by 9% over the prior-year quarter. Treasure Island has achieved
increases in revenues and operating income in each of the seven quarters where
year-to-year comparisons are possible. For the nine-month period, Treasure
Island's operating income increased 10% over the 1995 nine-month period.
 
    The Golden Nugget also had a strong quarter, achieving an 11% increase in
operating income on a 4% increase in net revenues, as compared to the prior-year
quarter. This continues the strong results that the property has shown since the
December 1995 opening of the Fremont Street Experience. For the nine-month
period, the Golden Nugget's operating income increased 38% over the prior-year
period.
 
    The Company-wide table games win percentage was 19.2% in the third quarter,
versus 20.3% in the prior-year quarter. By comparison, for the full years 1994
and 1995, the Company-wide win percentage was 18.8% and 20.2%, respectively.
 
    The Company's occupancy and average room rates reflect the continued
underlying strength of the Las Vegas market. Company-wide occupancy of standard
guest rooms increased to 99.2% for the third quarter, versus 98.8% for the
prior-year quarter. Meanwhile, the Company's average standard room rate
increased by 7%.
 
    Corporate expense declined 14% from the prior-year quarter, as management's
focus has shifted from potential legalization efforts to actual projects under
construction.
 
    Interest expense declined $4.3 million, or 80%, from the prior-year quarter
as the Company's construction-in-progress has increased, resulting in greater
capitalization of interest.

    The first half of 1996 set new records for the Company. Revenues, operating
income and income before non-recurring items were all records for the first six
months of any year in the Company's history, surpassing previous records set in
the first six months of 1995. Operating profit before Monte Carlo and corporate
expense grew by $22.6 million, or 15%, and earnings per share of $0.54
represents a 29% increase over the $0.42 before extraordinary item in the 1995
six-month period.
 
    Operating results at the Company's Las Vegas resorts were up strongly over
the 1995 period. The Mirage overcame a decline in the table games win percentage
to achieve increases of 6% in net revenues and 12% in operating income. The
Mirage's room enhancement program, which was completed in August 1995, yielded
strong returns throughout the first half of 1996. With 14% more available room
nights and a 16% increase in the average standard room rate, net room revenues
grew by $12.2 million, or 26%. Food and beverage, entertainment and retail
revenues also experienced solid increases. In total, net non-casino revenues
were up $20.1 million, or 15%, over the 1995 six-month period.
 
    Slot revenues at The Mirage increased by 6% and table games activity grew by
5%. The improvement in table games activity, however, was offset by the lower
win percentage, resulting in a small decline in total casino revenues.
 
    Treasure Island achieved a 5% increase in net revenues and a 10% increase in
operating income during the first half of 1996. These increases primarily
reflect an $8.1 million, or 8%, improvement in net non-casino revenues. Casino
revenues were relatively flat compared with the 1995 period. Net non-casino
revenues showed improvement in virtually every category. In particular, room
revenues grew by $5.1 million, or 13%, and entertainment revenues were up $1.3
million, or 7%. The growth in room revenues principally reflects an increase in
the average standard room rate. Increases in both occupancy and the average
ticket price for the Mystere show primarily account for the increase in
entertainment revenues.
 
    The Fremont Street Experience, which opened in December 1995, had a
significant positive impact on the Golden Nugget's operating results throughout
the first half of 1996. Net revenues grew by 15% and operating income was up
51%. The growth in revenues reflects increases of $7.7 million, or 13%, in
casino revenues and $5.6 million, or 17%, in net non-casino revenues. Slot
revenues were up 12%. Table games benefited from an increase in activity and a
more favorable win percentage, resulting in a 15% increase in revenues.
 
    Net room revenues at the Golden Nugget grew by $3.7 million, or 22%,
attributable to increases in both occupancy and the average room rate. Occupancy
of available standard guest rooms was 98.9%, versus 96.6% in the 1995 six-month
period. Food and beverage revenues increased $1.7 million, or 16%, accounting
for most of the remaining increase in net non-casino revenues.
 
    Weak market conditions hampered operating results at the Golden
Nugget-Laughlin during the first half of 1996. A $1.1 million decrease in slot
revenues led to a 5% decline in total net revenues and a 14% reduction in
operating income.
 
    Monte Carlo, the Company's joint venture hotel-casino with Circus, opened
June 21, 1996 on the Las Vegas Strip. For the 10-day period of operations in
June, this new mid-priced resort reported $9.0 million in total revenues and
$1.2 million in operating profit before the write-off of preopening costs. These
results were achieved despite what management believes is a lower than normal
table games win percentage and notwithstanding the inefficiencies inherent in
any new property's first few weeks of operation. Net of the write-off of all
$11.2 million in preopening costs, Monte Carlo had a $10.3 million net loss for
the period.
 
    Because Monte Carlo is a 50% owned venture, its operating results are not
consolidated with the Company's. Instead, the Company's $5.2 million share of
Monte Carlo's net loss for the 10-day period is included in the Company's gross
revenues.

<PAGE>
OTHER FACTORS AFFECTING EARNINGS
 
    Corporate expense declined by 23%, as management concentrated on developing
resorts in existing gaming jurisdictions rather than pursuing opportunities in
potential new jurisdictions.
 
    Interest and other income during the 1996 and 1995 periods include gains of
$4.5 million and $2.5 million, respectively, from the sale of investment
securities. At June 30, 1996, there were no securities remaining in the
Company's investment portfolio.
 
    Interest expense declined by $10.3 million, or 76%, due to a continued
reduction in debt levels coupled with an increase in capitalized interest, as
greater amounts are being invested in new projects.
 
    In February 1996, the Company sold its 50% equity interest in a small casino
located near Iguazu Falls, Argentina. The casino opened in July 1994 with a
total investment by the Company of $4.0 million. Although the casino was quite
profitable, contributing $1.4 million (on a pretax basis) to the Company's 1995
annual operating results, management determined that the facility was not
capable of being expanded into a resort of meaningful size to the Company.
Consequently, the Company's interest was sold for $12.5 million in cash,
resulting in a pretax gain of $8.0 million.
 
    In March 1995, the Company called for redemption the remaining $126.0
million principal amount of the 9 7/8% first mortgage notes associated with The
Mirage and Treasure Island. Although this early retirement was financially
advantageous to the Company, the call premium and the write-off of the related
unamortized debt issuance costs resulted in an extraordinary charge of $6.8
million ($0.04 per share) during the 1995 six-month period.
 
REGULATION AND TAXES
 
    The Company is subject to extensive regulation by the Nevada gaming
authorities and will be subject to regulation, which may or may not be similar
to that in Nevada, by the appropriate authorities in Mississippi, New Jersey and
any other jurisdiction in which it may conduct gaming activities in the future.
Changes in applicable laws or regulations could have a significant impact on the
Company's operations. Recently, legislation was enacted which established a
federal commission to study the gaming industry.
 
    The gaming industry represents a significant source of tax revenues,
particularly to the State of Nevada and its counties and municipalities. From
time to time, various state and federal legislators and officials have proposed
changes in tax law, or in the administration of such law, affecting the gaming
industry. Proposals in recent years that have not been enacted included a
federal gaming tax and increases in state or local gaming taxes. Other issues
under consideration by the Internal Revenue Service include limitations on the
federal income tax deductibility of furnishing complimentary promotional items
to customers, as well as various measures that would require withholding on
amounts won by customers or on discounts negotiated with foreign customers on
amounts owed to the Company.
 
    Management believes that the Company's recorded tax balances are adequate.
However, it is not possible to determine with certainty the likelihood of
possible changes in tax law or in the administration of such law. Such changes,
if adopted, could have a material adverse effect on the Company's operating
results.
 
COMPARISON OF THE YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
RESULTS OF OPERATIONS
 
    The Company achieved record operating results during 1995. Income before
extraordinary and non-recurring items of $169.9 million ($0.88 per share) was
36% greater than the previous record of $124.7 million ($0.66 per share)
achieved on the same basis in 1994. After deducting extraordinary charges on
early retirements of debt, the Company had net income of $163.2 million ($0.85
per share) in 1995, versus $114.3 million ($0.60 per share) in the prior year.
 
                                      S-13
<PAGE>
    The Company's net revenues during 1995 increased $76.6 million, or 6%,
reflecting substantial growth in both casino and non-casino revenues. The
Company's casinos achieved a 15% increase in table games revenues attributable
almost equally to a higher win percentage and a strong increase in the level of
activity, particularly baccarat play. The Company-wide table games win
percentage for the year was 20.2%, compared to 18.8% in 1994.
 
    Slot revenues increased 1% over 1994. However, the Company's other casino
revenues declined due primarily to a lower sports book win percentage.
 
    The Company's 1995 non-casino revenues net of promotional allowances
increased by $21.4 million, or 4%. A major contributor to this was a 23%
increase in entertainment revenues. This growth partially reflects a 16%
increase in the number of performances by Siegfried & Roy, whose performance
schedule was curtailed during 1994 due to knee surgery required by one of the
principal performers. Furthermore, the Mystere production achieved higher
occupancy and a higher average ticket price for the year. Both Siegfried & Roy
and Mystere played to average occupancy of nearly 100% during 1995. The increase
in ticket prices and showroom occupancy resulted in an improvement in gross
margins and profitability.
 
    Company-wide net room revenues increased 5% for the year. This was
particularly notable as the number of available room nights declined 4%, due to
construction relating to the enhancement and refurbishment of many of the guest
rooms at The Mirage and the Golden Nugget. Net revenues per available room night
at the Company's four hotels increased 8% over 1994. Company-wide occupancy of
standard guest rooms remained steady, at approximately 98%. The increase in
average room rate helped the Company achieve an increase in the gross margin on
room revenues.
 
    Treasure Island was the principal contributor to the substantial growth in
the Company's operating results in 1994. This exciting pirate-themed facility
opened on October 26, 1993, and contributed net revenues and operating income of
$343.0 million and $69.7 million, respectively, during its first full year of
operation. Treasure Island's 1994 net revenues consisted of casino revenues of
$152.5 million and non-casino revenues of $190.5 million.
 
    During its 66 days of operations in 1993, Treasure Island contributed net
revenues of $59.0 million and operating income (before preopening and related
promotional expense) of $8.5 million. Net revenues included casino revenues of
$30.6 million and non-casino revenues of $28.4 million.
 
    The combined net revenues and operating income of The Mirage and the
Company's two Golden Nugget properties increased 2% and 11%, respectively,
during 1994. Combined casino revenues of the three properties increased $19.4
million, or 3%, primarily resulting from a 5% improvement in table games
activity at The Mirage. Combined slot revenue of the three properties was up
$9.2 million, or 4%. Management attributes the improvement in part to the
mid-1994 completion of a program to install new upgraded slot machines at the
three facilities.
 
    Net non-casino revenues, excluding Treasure Island, were relatively
unchanged in 1994. This result was achieved despite approximately 16% fewer
performances by Siegfried & Roy and the November 1993 conclusion of Cirque du
Soleil's engagement at The Mirage.
 
OTHER FACTORS AFFECTING EARNINGS
 
    General and administrative expense in 1994 includes abandonment charges
totaling $12.4 million, principally reflecting an $11.0 million charge
associated with the room enhancement program at The Mirage. Various smaller
projects resulted in similar charges of $3.6 million in 1995 and $0.5 million in
1993. The Company's depreciation and amortization expense during 1995 declined
8%, principally due to certain equipment at The Mirage having five-year
depreciable lives becoming fully depreciated near the end of 1994.
 
    Corporate expense was essentially flat in 1995, after having increased 19%
from 1993 to 1994. The 1994 increase was primarily due to additional costs
associated with the Company's evaluation and
 
                                      S-14
<PAGE>
pursuit of opportunities in new gaming jurisdictions. Such activities diminished
during 1995, but were offset by general growth of the Company and various other
factors.
 
    The Company's policy is to expense as incurred all costs (except for land
acquisition costs) associated with potential new ventures until the likelihood
of construction is relatively certain. At December 31, 1995, capitalized
preopening costs relating to the Bellagio and the Beau Rivage projects totaled
$1.7 million.
 
    Preopening and related promotional expense in 1993 represents the write-off
of the costs associated with the development and opening of Treasure Island.
 
    Reflecting management's continuing efforts to reduce the Company's overall
cost of capital, interest cost declined by $36.5 million, or 41%, from 1993 to
1994, and further declined by $19.2 million, or 37%, in 1995. Total debt at
December 31, 1995 was $249.1 million, versus $363.6 million and $566.6 million
at year-end 1994 and 1993, respectively. Interest capitalized declined from
$25.1 million in 1993 to $7.8 million in 1994 as a result of the October 1993
completion of Treasure Island. Continuing development of Bellagio was the
primary reason for the small increase in interest capitalized to $9.6 million
during 1995.
 
    Non-operating items include the Company's former 50% joint venture interest
in the operations of Casino Iguazu. The facility, located near Iguazu Falls,
Argentina, opened in July 1994. The Company recognized income of $1.4 million
attributable to its share of the earnings of Casino Iguazu during 1995, versus a
$1.0 million loss in 1994. Such loss was principally attributable to the
Company's proportionate share of the facility's preopening costs.
 
    During all three years, the Company retired some of its more expensive debt
prior to its scheduled maturities. Although these retirements were financially
advantageous to the Company, the call premiums and the write-off of the related
unamortized debt issuance costs results in extraordinary charges.
 
FINANCIAL POSITION AND CAPITAL RESOURCES
 
    At September 30, 1996, the Company had net working capital of $54.3 million
and borrowings under the $1 billion revolving bank credit facility totaled
$113.0 million. Management believes that operating cash flow and remaining
amounts available under the revolving bank credit facility will provide the
Company with sufficient resources to meet its existing debt obligations and
capital expenditure requirements, including those relating to the development of
Bellagio and Beau Rivage (see "The Company--Current Expansion Projects"). Should
the Company proceed with the projects contemplated in Atlantic City (see "The
Company--Future Expansion") or undertake significant share repurchases,
additional financing would likely be required. It is anticipated that such
financing would be available through an increase in the borrowing capacity under
the revolving bank credit facility or the issuance of additional debt or equity
securities.
 
                              DESCRIPTION OF NOTES
 
    The following information concerning the 7.25% Notes Due October 15, 2006
(the "Notes") offered hereby supplements and should be read in conjunction with
the statements in the accompanying Prospectus under the caption "Description of
Debt Securities." Capitalized terms not otherwise defined herein shall have the
meanings given to them in the accompanying Prospectus.
 
GENERAL
 
    The Notes will be issued as Debt Securities under an Indenture to be dated
as of October 15, 1996 (the "Base Indenture"), and a Supplemental Indenture
thereto to be dated as of October 15, 1996 (the "Supplemental Indenture," and
together with the Base Indenture, the "Indenture"), each between the Company and
Firstar Bank of Minnesota, N.A. (the "Trustee"). Provisions of the Base
Indenture are more fully described in the accompanying Prospectus. The Notes
will be issued as unsecured obligations of the Company in an aggregate principal
amount of $250,000,000 and will mature on October 15, 2006. The Notes will bear
interest from October 30, 1996, payable semiannually in arrears on each April 15
and
 
                                      S-15
<PAGE>
October 15, commencing April 15, 1997, at the rate set forth on the cover page
of this Prospectus Supplement, to the persons in whose names the Notes are
registered on the preceding April 1 and October 1, respectively. Payment of the
principal of, and interest on, the Notes will not be guaranteed by any
subsidiary of the Company. All of the Company's principal operations are
conducted through subsidiaries. Most of such subsidiaries are obligors under the
Company's revolving bank credit facility but will have no obligation with
respect to the Notes.
 
RESTRICTIVE COVENANTS
 
    The Notes are entitled to the benefit of certain restrictive covenants
described in the accompanying Prospectus under the heading "Description of Debt
Securities--Covenants."
 
    In addition, the Notes are subject to the covenants described below.
 
    LIMITATION ON LIENS
 
    The Indenture will provide that the Company will not, and will not permit
any subsidiary to, create, incur, issue, assume or guarantee any Indebtedness of
the Company or any subsidiary secured by a Lien upon any Principal Property, or
upon shares of capital stock or evidences of Indebtedness issued by any
subsidiary which owns or leases a Principal Property and which are owned by the
Company or any subsidiary (whether such Principal Property, shares or evidences
of Indebtedness are now owned or are hereafter acquired by the Company), without
making effective provision to secure all of the Notes then outstanding by such
Lien, equally and ratably with (or prior to) any and all other Indebtedness
thereby secured, so long as such Indebtedness shall be so secured.
 
    The foregoing restrictions shall not apply, however, to: (a) Liens existing
on the date of original issuance of the Notes; (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 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 another
subsidiary of the Company; (f) purchase money security Liens on personal
property; (g) Liens to secure Indebtedness of joint ventures in which the
Company or a subsidiary has an interest, to the extent such Liens are solely on
property or assets of, or equity interests in, such joint ventures; (h) Liens in
favor of the United States of America or any State thereof, or any department,
agency or instrumentality or political subdivision thereof, to secure partial,
progress, advance or other payments; and (i) any extension, renewal, replacement
or refunding of any Lien referred to in the foregoing clauses (a) through (h),
PROVIDED, however, that the aggregate principal amount of Indebtedness secured
thereby and not otherwise authorized by the foregoing clauses shall not exceed
the aggregate principal amount of Indebtedness, plus any premium or fee payable
in connection with any such extension, renewal, replacement or refunding, so
secured at the time of such extension, renewal, replacement or refunding.
 
    Notwithstanding the foregoing, the Company and its subsidiaries may create,
incur, issue, assume or guarantee Indebtedness secured by Liens without equally
and ratably securing the Notes then outstanding, PROVIDED, that at the time of
such creation, incurrence, issuance, assumption or guarantee, after giving
effect thereto and to the retirement of any Indebtedness which is concurrently
being retired, the aggregate amount of all outstanding Indebtedness secured by
Liens so incurred (other than those Liens permitted by the preceding paragraph),
together with all outstanding Attributable Value of all sale and leaseback
transactions permitted by the last paragraph under "Limitation on Sale and
Leaseback Transactions," does not exceed 15% of the Consolidated Net Tangible
Assets of the Company.
 
                                      S-16
<PAGE>
    LIMITATION ON SALE AND LEASEBACK TRANSACTIONS
 
    Sale and leaseback transactions by the Company or any subsidiary involving
any Principal Property are prohibited unless the Company or such subsidiary
shall apply, or cause to be applied, to the retirement of its secured debt
within 120 days after the effective date of the sale and leaseback transaction,
an amount not less than the greater of (i) the net proceeds of the sale of the
Principal Property leased pursuant to such arrangement or (ii) the fair market
value of the Principal Property so leased. This restriction will not apply to a
sale and leaseback transaction involving the taking back of a lease for a period
of less than three years.
 
    Notwithstanding the restrictions described above, the Company or any
subsidiary may enter into a sale and leaseback transaction, PROVIDED, that at
the time of such transaction, after giving effect thereto, the Attributable
Value thereof, together with all Indebtedness secured by Liens permitted
pursuant to the Indenture as described above under "Limitation on Liens" (other
than those Liens permitted by the second paragraph under "Limitation on Liens"
above, and other than the Attributable Value of the sale and leaseback
transactions permitted by the preceding paragraph) does not exceed 15% of
Consolidated Net Tangible Assets of the Company.
 
OPTIONAL REDEMPTION
 
    The Notes will be redeemable, in whole or in part, at the option of the
Company at any time at a redemption price equal to the greater of (i) 100% of
the principal amount of such Notes or (ii) as determined by a Quotation Agent,
the sum of the present values of the remaining scheduled payments of principal
and interest thereon discounted to the redemption date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate, plus, in each case, accrued interest thereon to the date of
redemption.
 
    Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of the Notes to be redeemed.
 
    Unless the Company defaults in payment of the redemption price, interest
will cease to accrue on the Notes or portions thereof called for redemption on
and after the redemption date.
 
    The Notes will not be entitled to the benefit of a sinking fund.
 
SUCCESSOR CORPORATION AND ASSIGNMENT
 
    The Indenture will provide that the Company may not consolidate or merge
with or into, or sell, lease, convey or otherwise dispose of all or
substantially all of its assets to, another person unless (i) the successor, if
other than the Company, is a corporation organized under the laws of the United
States or any state thereof or the District of Columbia, (ii) the successor, if
other than the Company, assumes all obligations of the Company under the Notes
and the Indenture, (iii) immediately after such transaction no Default or Event
of Default exists under the Indenture and (iv) if, as a result of the
transaction, property of the Company would become subject to a Lien that would
not be permitted under the limitation on Liens described above under
"Restrictive Covenants," the Company takes such steps as shall be necessary to
secure the Notes equally and ratably with (or prior to) the Indebtedness secured
by such Lien. Upon the occurrence of such a consolidation, merger or transfer in
which there is a successor other than the Company, all such obligations of the
Company will terminate.
 
EVENTS OF DEFAULT AND NOTICE THEREOF
 
    The term "Event of Default," when used in the Indenture with respect to the
Notes, will mean any one of the following: (i) failure of the Company to pay
(whether or not prohibited by applicable subordination provisions, if any),
interest for 30 days on, or the principal when due of, any Notes; (ii) failure
of the Company to comply with any of its other agreements or other covenants
contained in the Notes or in such Indenture and applicable to the Notes, and
continuance of such default for 30 days after notice (or in the case of certain
defaults, without notice); (iii) failure to pay when due (after applicable grace
periods
 
                                      S-17

as provided in any applicable instrument governing such Indebtedness) the
principal of, or acceleration of, any Indebtedness for money borrowed by the
Company having an aggregate principal amount outstanding equal to at least $25
million, if such Indebtedness is not discharged, or such acceleration is not
annulled, within 30 days after written notice as provided in the Indenture; (iv)
entry of final judgments against the Company or any subsidiary or subsidiaries
of the Company which remain undischarged for a period of 60 days, provided that
the aggregate of all such judgments exceeds $25,000,000 and the judgments remain
undischarged for 60 days after notice; (v) certain events of bankruptcy,
insolvency or reorganization; and (vi) a revocation, suspension or involuntary
loss of any Gaming License by the Company or a subsidiary of the Company (after
the same shall have been obtained) which results in the cessation of operation
of the business at a Principal Property for a period of more than 90 consecutive
days.

Treasury Dealer and any redemption date, the average, as determined by the
Trustee, of the bid and asked prices for the Comparable Treasury Issue

BOOK-ENTRY SYSTEM
 
    The Notes will be represented by Global Securities that will be deposited
with, or on behalf of, DTC and registered in the name of a nominee of DTC.
 
    DTC has advised the Company and the Underwriters as follows: DTC is a
limited-purpose trust company organized under the New York Banking Law, a
"banking organization" within the meaning of the New York Banking Law, a member
of the Federal Reserve System, a "clearing corporation" within the meaning of
the New York Uniform Commercial Code and a "clearing agency" registered pursuant
to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC was
created to hold securities of its participating organizations ("participants")
and to facilitate the clearance and settlement of securities transactions, such
as transfers and pledges, among its participants in such securities through
electronic computerized book-entry changes in accounts of the participants,
thereby eliminating the need for physical movement of securities certificates.
Participants include securities brokers and dealers (including the
Underwriters), banks, trust companies, clearing corporations and certain other
organizations, some of whom (and/or their representatives) own DTC. Access to
DTC's book-entry system is also available to others, such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly. Persons who are
not participants may beneficially own securities held by DTC only through
participants.
 
    Unless and until they are exchanged in whole or in part for certificated
Notes in definitive form, the Global Securities may not be transferred except as
a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another
nominee of DTC.
 
    The Notes represented by the Global Securities will not be exchangeable for
certificated Notes, PROVIDED that if DTC is at any time unwilling, unable or
ineligible to continue as depositary and a successor depositary is not appointed
by the Company within 90 days, the Company will issue individual Notes in
definitive form in exchange for the Global Securities. In addition, the Company
may at any time and in its sole discretion determine not to have Global
Securities and, in such event, will issue individual Notes in definitive form in
exchange for the Global Securities previously representing all such Notes. In
either instance, an owner of a beneficial interest in a Global Security will be
entitled to physical delivery of Notes in definitive form equal in principal
amount to such beneficial interest and to have such Notes registered in its
name. Individual Notes so issued in definitive form will be issued in
denominations of $1,000 and any larger amount that is an integral multiple of
$1,000 and will be issued in registered form only, without coupons.
 
    Payments of principal of and interest on the Notes will be made by the
Company through the Trustee to DTC or its nominee, as the case may be, as the
registered owner of the Global Securities. Neither the Company nor the Trustee
will have any responsibility or liability for any aspect of the records relating
to
 
                                      S-19
<PAGE>
or payments made on account of beneficial ownership interests of the Global
Securities or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests. The Company expects that DTC, upon receipt
of any payment of principal or interest in respect of the Global Securities,
will credit the accounts of the related participants with payment in amounts
proportionate to their respective holdings in principal amount of beneficial
interest in the Global Securities as shown on the records of DTC. The Company
also expects that payments by participants to owners of beneficial interests in
the Global Securities will be governed by standing customer instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of such participants.
 
                                  UNDERWRITING
 
    Subject to the terms and conditions set forth in the Underwriting Agreement
and the Pricing Agreement, the Company has agreed to sell to each of the
Underwriters named below, and each of such Underwriters, for whom Goldman, Sachs
& Co. and CS First Boston Corporation are acting as representatives (the
"Representatives"), has severally agreed to purchase, the principal amount of

</TABLE>
 
    Under the terms and conditions of the Underwriting Agreement and the Pricing
Agreement, the Underwriters are committed to take and pay for all of the Notes,
if any are taken.
 
    The Underwriters propose to offer the Notes in part directly to the public
at the initial public offering price set forth on the cover page of this
Prospectus Supplement and in part to certain securities dealers at such price
less a concession of 0.40% of the principal amount of the Notes. The
Underwriters may allow, and such dealers may reallow, a concession not to exceed
0.25% of the principal amount of the Notes to certain brokers and dealers. After
the Notes are released for sale to the public, the offering price and other
selling terms may from time to time be varied by the Representatives.
 
    The Notes are a new issue of securities with no established trading market.
The Company has been advised by the Representatives that the Representatives
intend to make a market in the Notes but are not obligated to do so and may
discontinue market making at any time without notice. No assurance can be given
as to the liquidity of the trading market for the Notes.
 
    The Company has agreed to indemnify the several Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933.
 
    In the ordinary course of their respective businesses, certain of the
Underwriters and their affiliates engage and may in the future engage in
investment banking and commercial banking activities with the
 
                                      S-20

Company and its subsidiaries. Each of ABN AMRO Securities (USA) Inc., BA
Securities, Inc., BT Securities Corporation, CIBC Wood Gundy Securities Corp.
and Societe Generale Securities Corporation is a lender or an affiliate of a
lender to the Company under the Company's revolving bank credit facility. The
Company intends to use a significant portion of the net proceeds from the sale
of the Notes to repay outstanding amounts due under the revolving bank credit
facility. See "Use of Proceeds." As a result, this offering of the Notes is
being made pursuant to the provisions of Rule 2710(c)(8) of the Conduct Rules of
The National Association of Securities Dealers, Inc.
 
                                 LEGAL MATTERS
 
    Certain legal matters in connection with this offering will be passed upon
for the Company by Wolf, Block, Schorr and Solis-Cohen, Philadelphia,
Pennsylvania, and for the Underwriters by Latham & Watkins, Los Angeles,
California. Certain legal matters with respect to Nevada law will be passed upon
by Peter C. Walsh, Assistant General Counsel of the Company.

    The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for forward-looking statements. Certain information included in this

of regulation (including gaming and tax regulation) and competition. Such
forward-looking information involves important risks and uncertainties that
could significantly affect anticipated results in the future and, accordingly,
such results may differ from those expressed in any forward-looking statements
made herein or therein. These risks and uncertainties include, but are not
limited to, those relating to development and construction activities,
dependence on existing management, leverage and debt service (including
sensitivity to fluctuations in interest rates), domestic or global economic

laws and changes in gaming laws or regulations (including the legalization of
gaming in certain jurisdictions).

                                  THE COMPANY
 
    The Company, through wholly owned subsidiaries, owns and operates (i) The
Mirage, a hotel-casino and destination resort on the Las Vegas Strip, (ii)
Treasure Island at The Mirage ("Treasure Island"), a hotel-casino resort
adjacent to The Mirage, (iii) the Golden Nugget, a hotel-casino in downtown Las
Vegas, and (iv) the Golden Nugget-Laughlin, a hotel-casino in Laughlin, Nevada.
The Company, through a wholly owned subsidiary, also owns a 50% interest in a
joint venture which owns and operates Monte Carlo, a mid-priced hotel-casino
resort on the Las Vegas Strip which opened on June 21, 1996.
 
    The Company, through a wholly owned subsidiary, is constructing "Bellagio,"
a major new 3,000-guest room luxury hotel, casino and resort facility on
approximately 120 acres adjacent to Monte Carlo, scheduled to open in the spring
of 1998.
 
    The Company, through wholly owned subsidiaries, owns approximately 18 acres
of land in Biloxi, Mississippi on which it is constructing a casino-based
destination resort. The planned facility will be a luxurious resort featuring a
waterfront casino, more than 1,800 hotel rooms, a variety of restaurants and
other amenities. Construction is expected to be completed in early 1998 at a
total cost, including land and capitalized interest, of approximately $500
million.
 
    The Company and the City of Atlantic City, New Jersey have entered into a
redevelopment agreement providing for the City to convey 150 acres owned by the
City, located in the Marina area of Atlantic City, to the Company in exchange
for the Company agreeing to develop a casino-based destination resort on the
site and undertaking certain other obligations, including remediation of
environmental contamination and the relocation of City-owned facilities
currently located on the site. Closing under the redevelopment agreement
requires the satisfaction of a number of conditions, including the receipt by
the Company of all requisite licenses, permits, allocations and authorizations,
resolution of real estate title issues, the Company determining that the costs
of environmental remediation are not unreasonable and the approval by the State
of New Jersey of funding for certain major roadway improvements affecting the
site. Accordingly, there can be no assurance as to whether or when the Company
will proceed with the project. As currently proposed, the project, if developed,
would include the Company's construction of a luxury hotel-casino featuring
approximately 2,000 guest rooms, a 115,000-square foot casino, a variety of
restaurants, a large entertainment and retail concourse and other amenities. The
Company, which will act as master developer of the entire site, has entered into
separate agreements with Boyd Gaming Corporation ("BGC") and Circus Circus
Enterprises, Inc. ("Circus"), pursuant to which the Company and BGC will,
through a joint venture, construct a hotel-casino resort containing a minimum of
1,000 guest rooms on a portion of the site and Circus will acquire a portion of
the site from the Company and construct an additional 2,000-room hotel-casino
resort in architectural formats that conform to an agreed-to master plan.
Development of the projects by the joint venture and Circus are also contingent
upon the satisfaction of the conditions to the Company's obligation to develop
its wholly owned resort.
 
    The Company was incorporated in Nevada in 1949 as the successor to a
partnership that began business in 1946. Its executive offices are located at
3400 Las Vegas Boulevard South, Las Vegas, Nevada 89109; telephone (702)
791-7111.

                                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 (including Bellagio and the currently
contemplated projects in Biloxi, Mississippi and Atlantic City, New Jersey),
capital expenditures and working capital, to repay or repurchase outstanding
indebtedness of the Company or its subsidiaries or for such other purposes as
may be specified in an accompanying Prospectus Supplement.
 
                         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
unsecured debt, senior subordinated debt or subordinated debt, or any
combination thereof, of the Company. One or more series of Debt Securities may
be issued under a single indenture amended in the case of each subsequent series
of Debt Securities by a supplemental indenture to include the additional terms
applicable to such series, or alternatively, any series of Debt Securities may
be issued under a separate indenture. Each indenture pursuant to which any Debt
Securities are issued (hereinafter referred to as an "Indenture," and
collectively with any other Indentures, as the "Indentures") will be entered
into between the Company, as obligor, and an institution to be named in the
applicable Prospectus Supplement, as trustee (the "Trustee").
 
    The terms of any series 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 of 1939, as amended (the "Trust Indenture Act"). Holders of
each series of the Debt Securities are referred to the Indenture for such series
and the Trust Indenture Act for a statement of such terms. A copy of the form of
Indenture for the Debt Securities, which may be amended or modified for any
series of Debt Securities as described in an applicable Prospectus Supplement,
is filed as an exhibit to the Registration Statement. The following summaries of
certain provisions of the Debt Securities and the Indenture for such Debt
Securities do not purport to be complete and are subject to, and are qualified
in their entirety by reference to, all of the provisions of the Debt Securities
and such Indenture, including the definitions therein of certain terms
 
                                       4
<PAGE>
which are not otherwise defined in this Prospectus, and the Prospectus
Supplement(s) and supplemental indenture(s) with respect thereto. Wherever
particular provisions or defined terms of an Indenture are referred to, such
provisions or defined terms are incorporated herein by reference.
 
GENERAL
 
    An Indenture 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. As of the date of this Prospectus, the Company has
authorized the issuance under the Indentures of Debt Securities, the aggregate
initial offering price of which (represented by the aggregate principal amount
of Debt Securities issued at their principal amount or the issue price of Debt
Securities issued at an original issue discount) does not exceed $500 million.
Each series of Debt Securities will be denominated in United States dollars
unless otherwise provided in the Prospectus Supplement relating thereto. The
Debt Securities will be issued in denominations of $1,000 and integral multiples
thereof unless otherwise provided in the Prospectus Supplement relating thereto.
 
    The applicable Prospectus Supplement or Prospectus Supplements will
describe, among other things, the following terms of the Debt Securities, to the
extent applicable to such Debt Securities: (i) the title of the Debt Securities
and, if other than denominations of $1,000 and any integral multiple thereof,
the denominations in which any Debt Securities shall be issuable; (ii) any limit
on the aggregate principal amount of the Debt Securities and any provisions
relating to the seniority or subordination of all or any portion of the
indebtedness evidenced thereby to other indebtedness of the Company; (iii) the
price or prices (expressed as a percentage of the respective 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), 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 dates, if any, on
which any interest on the Debt Securities will be payable, the record date for
any interest payable on any Debt Securities and the person to whom interest
shall be payable if other than the person in whose name the Debt Security is
registered at the close of business on the record date for such interest; (vii)
the place or places where principal of, premium, if any, and interest on the
Debt Securities shall be payable; (viii) the terms applicable to any "original
issue discount" (as defined in the Internal Revenue Code of 1986, as amended,
and the regulations thereunder), including the rate or rates at which such
original issue discount shall accrue; (ix) 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; (x) 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; (xi) 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; (xii) 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; (xiii) any listing of
the Debt Securities on a securities exchange; (xiv) any restrictive covenants
included for the benefit of Holders of such Debt Securities; (xv) any additional
events of default provided with respect to such Debt Securities; (xvi) the
terms, if any, on which such Debt Securities will be convertible into or
exchangeable for other debt or equity securities; (xvii) the collateral, if any,
securing payments with respect to such Debt Securities and any provisions
relating thereto; and (xviii) any other material terms of the Debt Securities.
Any such Prospectus Supplement will
 
                                       5
<PAGE>
also describe any special provisions for the payment of additional amounts with
respect to the Debt Securities.
 
MANDATORY DISPOSITION PURSUANT TO GAMING LAWS
 
    An Indenture will provide that each Holder, by accepting any of the Debt
Securities subject thereto, shall be deemed to have agreed that if any Gaming
Authority of any jurisdiction that holds regulatory, licensing or permit
authority over the gaming or gaming-related activities of the Company or any of
its subsidiaries or any joint venture or other entity in which the Company or
any of its subsidiaries owns an interest requires that a person who is a Holder
of Debt Securities or the beneficial owner of the Debt Securities of a Holder
must be licensed, qualified or found suitable under applicable Gaming Laws, such
Holder or beneficial owner, as the case may be, shall apply for a license,
qualification or a finding of suitability, as the case may be, within the
required time period. Such Indenture will further provide that if such person
fails to apply or become licensed or qualified or is found unsuitable (in each
case, a "failure of compliance"), 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 such Gaming
Authority or (ii) to redeem within such 30-day or earlier period requested or
prescribed by such Gaming Authority such Debt Securities at a redemption price
equal to the lesser of (a) such person's cost or (b) 100% of the principal
amount thereof, together, in either case, with accrued and unpaid interest to
the earlier of the redemption date or the date of the failure of compliance,
which may be less than 30 days following the notice of redemption if so
requested or prescribed by such Gaming Authority. The Company shall notify the
Trustee under such Indenture 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 owner may incur in connection with its application for a license,
qualification or finding of suitability.
 
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 (each, a "Depositary") or its nominee identified in
the applicable Prospectus Supplement. In such case, one or more registered
Global Securities will be issued, each in a denomination equal to the portion of
the aggregate principal amount of outstanding registered Debt Securities of the
series to be represented by such registered Global Security. 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 (collectively, the "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
 
                                       6
<PAGE>
certain 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 Indenture applicable thereto. 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 Indenture applicable thereto.
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 Indenture applicable to such registered Global
Security. 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 under the applicable Indenture or any other
agent of the Company or agent of such 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 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 each registered Global Security
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 Trustee. 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.

COVENANTS
 
    PUT OPTION UPON CHANGE IN CONTROL
 
    If there is a Change in Control (the time of a Change in Control being
referred to as the "Change in Control Date"), then the Company will (a)
commence, within five business days following the Change in Control Date, an
offer to repurchase (the "Repurchase Offer") all of the then outstanding Debt
Securities at a price (the "Repurchase Price") of 101% of the principal amount,
plus accrued interest to the Repurchase Date (as defined below) and (b) deposit
with the Paying Agent an amount equal to the aggregate Repurchase Price for all
Debt Securities then outstanding so as to be available for payment to holders of
Debt Securities who elect to require the Company to repurchase all or a portion
of their Debt Securities.
 
    An Indenture will require the Repurchase Offer to remain open from the time
of mailing until 10 business days thereafter, unless a longer period is required
by law or stock exchange rule or unless a majority of the Continuing Directors
of the Company votes in favor of extending such period (the date on which the

principal when due of, any Debt Securities of such series; (ii) failure of the
Company to comply with any of its other agreements or other covenants contained

notice (or in the case of certain defaults, without notice); (iii) the
occurrence of an event of default under any instrument evidencing Indebtedness
of the Company or of any subsidiary of the Company (or the payment of which is
guaranteed by the Company or any subsidiary of the Company), if (a) such event
of default results from the failure to pay principal of or interest upon
maturity on any such Indebtedness, (b) the principal amount of such
Indebtedness, together with the principal amount of any other such Indebtedness
in default for failure to pay principal or interest thereon upon maturity,
aggregates $50,000,000 or more and (c) the default continues for a period of 60

    An Indenture will provide that the Trustee thereunder will, within 90 days
after the occurrence of a default with respect to the Debt Securities subject
thereto, give the holders of such Debt Securities notice of all uncured defaults
known to it (the term "default" to include the events specified above without
grace or notice), provided, that, except in the case of a default in the payment
of principal of or interest on such Debt Securities, such Trustee shall be
protected in withholding such notice if and so long as a committee of its trust
officers in good faith determines that the withholding of such notice is in the
interest of the holders of such Debt Securities.
 
    In case an Event of Default (other than certain events of bankruptcy,
insolvency or reorganization) occurs and is continuing with respect to any
series of Debt Securities, the Trustee under the Indenture relating to such
series of Debt Securities or the holders of not less than 25% in principal
amount of such series of Debt Securities then outstanding, by notice in writing
to the Company (and to such Trustee if given by the holders of such series of
Debt Securities), may declare the unpaid principal of and all accrued and unpaid
interest on all such series of Debt Securities 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 with respect to such series of
Debt Securities (except non-payment of principal of or interest on such series
that has become due solely because of the acceleration) 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.
 
    An Indenture will include a covenant that the Company will (so long as it
has not been relieved of the obligation by covenant defeasance or discharge of
such Indenture in accordance with the terms thereof) file annually with the
Trustee under such Indenture a statement regarding compliance by the Company
with the terms thereof and specifying any defaults thereunder of which the
signers may have knowledge.
 
                                       10
<PAGE>
MODIFICATION OF THE INDENTURES
 
    Under an Indenture, the rights and obligations of the Company and the rights
of the holders of the Debt Securities covered by such Indenture generally may be
modified by the Company and the Trustee under such Indenture with the consent of
the holders of not less than a majority in principal amount of the Debt
Securities then outstanding affected by such modification. Notwithstanding the
foregoing, without the consent of each affected holder of Debt Securities, an
amendment or waiver with respect to such Indenture may not (i) reduce the amount
of Debt Securities whose holders must consent to an amendment, supplement or
waiver; (ii) reduce the rate of or change the time for payment of interest on
any Debt Security in a manner adverse to the holders thereof; (iii) reduce the
principal of, or extend the stated maturity of any Debt Security or alter the
redemption provisions of any Debt Securities in a manner adverse to the holders
thereof; (iv) make any Debt Security payable in money other than that stated in
such Debt Security; (v) waive a default in the payment of the principal of, or
interest on, any Debt Security; or (vi) take any other action, if any, described
in a Prospectus Supplement as requiring the consent of each affected holder of
Debt Securities. Under certain circumstances, the Company and the Trustee may
amend or supplement an Indenture without notice to or the consent of any holder
of the Debt Securities covered by such Indenture.
 
SATISFACTION AND DISCHARGE OF INDENTURES
 
    Unless otherwise indicated in the applicable Prospectus Supplement, the
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 or Qualified Government
Obligations, or both, which, together with the predetermined and certain income
to accrue thereon, without consideration of any reinvestment thereof, will
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, in accordance with the terms of such
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 to the effect that 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 in the same
manner as would have been the case if such deposit and defeasance had not
occurred.
 
COVENANT DEFEASANCE
 
    Unless otherwise indicated in the applicable Prospectus Supplement, an
Indenture will provide that the Company may be released from its obligations
with respect to any series of Debt Securities to which such Indenture relates
other than the Company's obligations with respect to the payment of principal
of, premium, if any, and interest on such series of Debt Securities, and that
such release will not be deemed to be an Event of Default under such Indenture
with respect to any such series of Debt Securities ("covenant defeasance"), upon
the deposit with the Trustee (or other qualifying trustee), in trust, of money
or Qualified Government Obligations, or both, which through the payment of
interest and principal in accordance with their terms will 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 to the effect that 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 and will be subject to federal
income tax in the same manner as would have been the case if such covenant
defeasance had not occurred.
 
                                       11
<PAGE>
CONCERNING THE TRUSTEE
 
    The applicable Prospectus Supplement relating to each issuance of Debt
Securities will identify the Trustee under the Indenture relating to such Debt
Securities. If more than one series of Debt Securities is outstanding under an
Indenture, a Trustee may serve in such capacity with respect to the Debt
Securities of one or more of such series. If more than one series of Debt
Securities is outstanding under an Indenture, the holders of a majority in
aggregate principal amount of each such series at any time outstanding may
remove the Trustee with respect to such series (but not as to any other series)
by so notifying the Trustee and may appoint a successor Trustee with respect to
such series. Each reference in this Prospectus to the Trustee under an Indenture
refers, in the case of each series of Debt Securities outstanding under such
Indenture, to the Trustee for such series. Except as otherwise described in the
applicable Prospectus Supplement or provided for in an Indenture, payments of
principal of, premium, if any, and interest on, and all registration, transfer,
exchange, authentication and delivery (including authentication and delivery on
original issuance of the Debt Securities) of, Debt Securities issued under such
Indenture will be effected by the Trustee under the Indenture applicable to such
Debt Securities at such Trustee's corporate trust office, or at an office
designated by such Trustee in New York, New York.
 
    An Indenture will contain certain limitations on the right of the Trustee
under such Indenture, should it become a creditor of the Company, to obtain
payment of claims in certain cases or to realize on certain property received in
respect of any such claim as security or otherwise. The Trustee under each
Indenture will be permitted to engage in other transactions; however, if a
Trustee acquires any conflicting interest, it must eliminate such conflict or
resign its position as Trustee.
 
    The holders of a majority in principal amount of any series of Debt
Securities then outstanding under an Indenture will have the right to direct the
time, method and place of conducting any proceeding for exercising any remedy
available to the Trustee under such Indenture applicable to such series of Debt
Securities, provided that such direction would not conflict with any rule of law
or with such Indenture, would not be unduly prejudicial to the rights of another
holder of such Debt Securities and would not involve such Trustee in personal
liability. An Indenture will provide that in case an Event of Default under such
Indenture shall occur and be known to the Trustee under such Indenture (and not
be cured), such Trustee will be required to use the degree of care of a prudent
person in the conduct of such person's own affairs in the exercise of its power.
Subject to such provisions, a Trustee will be under no obligation to exercise
any of its rights or powers under such Indenture at the request of any of the
holders of the Debt Securities to which the Indenture relates unless such
holders shall have offered to such Trustee security and indemnity satisfactory
to it.
 
NO PERSONAL LIABILITY
 
    An Indenture 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 to which such Indenture relates or for any claim based on,
in respect of or by reason of such obligations or their creation, by reason of
such person's status as such director, officer, employee, stockholder or
incorporator.
 
                         DESCRIPTION OF PREFERRED STOCK
 
GENERAL
 
    The Company may issue, from time to time, shares of one or more series of
Preferred Stock.
 
    The following description of the terms of the Preferred Stock sets forth
certain general terms and provisions of the Preferred Stock to which any
Prospectus Supplement may relate. The particular terms of any series of
Preferred Stock offered by any Prospectus Supplement and the extent, if any, to
which such general provisions may apply to the series of Preferred Stock so
offered will be described in a Prospectus Supplement relating to such Preferred
Stock. The following summary of certain provisions of the Preferred Stock does
not purport to be complete and is subject to, and is qualified in its entirety
by
 
                                       12
<PAGE>
express reference to, the provisions of the Company's Articles of Incorporation,
as amended (the "Articles of Incorporation"), and each Certificate of
Designation relating to a specific series of the Preferred Stock (each, a
"Certificate of Designation"), which will be in the form filed as an exhibit to,
or incorporated by reference in, the Registration Statement at or prior to the
time of issuance of such series of Preferred Stock.
 
    Pursuant to the Articles of Incorporation, the Company has the authority to
issue 5,000,000 shares of Preferred Stock. The Board of Directors of the Company
is authorized to issue shares of Preferred Stock, in one or more series, and to
fix for each such series voting powers and such preferences and relative,
participating, optional or other special rights and such qualifications,
limitations or restrictions, as are permitted by the Nevada Revised Statutes.
 
    The Board of Directors of the Company is authorized to determine for each
series of Preferred Stock, and the Prospectus Supplement shall set forth with
respect to such series, the following: (i) the designation of such series and
the number of shares that constitute such series; (ii) the dividend rate (or the
method of calculation thereof), if applicable, on the shares of such series and
the priority as to payment of dividends with respect to other classes or series
of capital stock of the Company; (iii) the dividend periods (or the method of
calculation thereof), if applicable; (iv) the voting rights, if any, of the
shares; (v) the liquidation preference and the priority as to payment of such
liquidation preference with respect to other classes or series of capital stock
of the Company and any other rights of the shares of such series upon any
liquidation or winding-up of the Company; (vi) whether or not and on what terms
the shares of such series will be subject to redemption or repurchase at the
option of the Company; (vii) whether and on what terms the shares of such series
will be convertible into or exchangeable for other debt or equity securities;
(viii) whether depositary shares representing shares of such series of Preferred
Stock will be offered and, if so, the fraction of a share of such series of
Preferred Stock represented by each depositary share (see "Description of
Depositary Shares" below); (ix) whether the shares of such series of Preferred
Stock will be listed on a securities exchange; and (x) the other rights and
privileges and any qualifications, limitations or restrictions of such rights or
privileges of such series.
 
DIVIDENDS
 
    Holders of shares of Preferred Stock shall be entitled to receive, when and
as declared by the Board of Directors of the Company out of funds of the Company
legally available therefor, cash dividends payable on such dates and at such
rates, if any, per share set forth in the applicable Prospectus Supplement.
 
    Unless otherwise set forth in the applicable Prospectus Supplement, each
series of Preferred Stock will rank junior as to dividends to any series of
Preferred Stock that may be issued in the future that is expressly senior as to
dividends to such earlier series of the Preferred Stock. If at any time the
Company has failed to pay accrued dividends on any such senior series at the
time dividends are payable on a junior series, the Company may not pay any
dividend on such junior series of Preferred Stock or redeem or otherwise
repurchase shares of such junior series of Preferred Stock until such
accumulated but unpaid dividends on the senior series have been paid or set
aside for payment in full by the Company.
 
    Unless otherwise set forth in the applicable Prospectus Supplement, no
dividends (other than in Common Stock or other capital stock ranking junior to
the Preferred Stock of any series as to dividends and upon liquidation) shall be
declared or paid or set aside for payment, nor shall any other distribution be
declared or made upon the Common Stock, or any other capital stock of the
Company ranking junior to or on a parity with the Preferred Stock of such series
as to dividends, nor shall any Common Stock or any other capital stock of the
Company ranking junior to or on a parity with the Preferred Stock of such series
as to dividends be redeemed, purchased or otherwise acquired for any
consideration (or any monies be paid to or made available for a sinking fund for
the redemption of any shares of any such stock) by the Company (except by
conversion into or exchange for other capital stock of the Company ranking
junior to the Preferred Stock of such series as to dividends) unless (i) if such
series of Preferred Stock has a cumulative dividend, full cumulative dividends
on the Preferred Stock of such series have
 
                                       13
<PAGE>
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof set apart for all past dividend periods and the then
current dividend period or (ii) if such series of Preferred Stock does not have
a cumulative dividend, full dividends on the Preferred Stock of such series have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof set apart for payment for the then current dividend
period; provided, however, that any monies theretofore deposited in any sinking
fund with respect to any Preferred Stock of the Company in compliance with the
provisions of such sinking fund may thereafter be applied to the purchase or
redemption of such Preferred Stock in accordance with the terms of such sinking
fund, regardless of whether at the time of such application full cumulative
dividends upon shares of the Preferred Stock outstanding on the last dividend
payment date shall have been paid or declared and set apart for payment; and
provided, further, that any such junior or parity Preferred Stock of the Company
or Common Stock of the Company may be converted into or exchanged for stock of
the Company ranking junior to the series of Preferred Stock then senior to such
junior or parity Preferred Stock as to dividends.
 
    The amount of dividends payable for the initial dividend period or any
period shorter than a full dividend period shall be computed on the basis of a
360-day year of twelve 30-day months. Accrued but unpaid dividends will not bear
interest.
 
CONVERTIBILITY
 
    No series of Preferred Stock will be convertible into, or exchangeable for,
other securities or property except as set forth in the applicable Prospectus
Supplement.
 
REDEMPTION AND SINKING FUND
 
    No series of Preferred Stock will be redeemable or receive the benefit of a
sinking fund except as set forth in the applicable Prospectus Supplement.
 
LIQUIDATION RIGHTS
 
    Unless otherwise set forth in the applicable Prospectus Supplement, in the
event of any liquidation, dissolution or winding-up of the Company, the holders
of shares of each series of Preferred Stock are entitled to receive out of
assets of the Company available for distribution to stockholders, before any
distribution of assets is made to holders of: (i) any other shares of Preferred
Stock of the Company ranking junior to such series of Preferred Stock as to
rights upon liquidation, dissolution or winding-up; or (ii) shares of Common
Stock, liquidating distributions per share in the amount of the liquidation
preference specified in the applicable Prospectus Supplement for such series of
Preferred Stock plus any dividends accrued and accumulated but unpaid to the
date of final distribution, but, in either case, the holders of each series of
Preferred Stock will not be entitled to receive the liquidating distribution of,
plus such dividends on, such shares until the liquidation preference of any
shares of the Company's capital stock ranking senior to such series of the
Preferred Stock as to the rights upon liquidation, dissolution or winding-up
shall have been paid (or a sum set aside therefor sufficient to provide for
payment) in full. If upon any liquidation, dissolution or winding-up of the
Company, funds available for such purpose are insufficient to pay in full the
amounts payable with respect to any series of the Preferred Stock, and any other
Preferred Stock ranking as to any such distribution on a parity with such series
of the Preferred Stock, the holders of such series of the Preferred Stock of the
Company and such other parity Preferred Stock will share ratably in any such
distribution of assets in proportion to the full respective preferential amounts
to which they are entitled. Unless otherwise specified in a Prospectus
Supplement for a series of Preferred Stock, after payment of the full amount of
the liquidating distribution to which they are entitled, the holders of shares
of Preferred Stock will not be entitled to any further participation in any
distribution of assets by the Company. Neither a consolidation or merger of the
Company with another corporation nor a sale of securities shall be considered a
liquidation, dissolution or winding-up of the Company.
 
                                       14
<PAGE>
VOTING RIGHTS
 
    Holders of Preferred Stock will not have any voting rights except as set
forth in the applicable Prospectus Supplement or as otherwise from time to time
required by law.
 
MISCELLANEOUS
 
    The holders of Preferred Stock will have no preemptive rights. The Preferred
Stock, upon issuance against full payment of the purchase price therefor, will
be fully paid and nonassessable. Shares of Preferred Stock redeemed or otherwise
reacquired by the Company shall resume the status of authorized and unissued
shares of Preferred Stock undesignated as to series, and shall be available for
subsequent issuance. There are no restrictions on repurchase or redemption of
the Preferred Stock on account of any arrearage on sinking fund installments
except as may be set forth in an applicable Prospectus Supplement. Payment of
dividends on any series of Preferred Stock may be restricted by loan agreements,
indentures or other agreements entered into by the Company. The accompanying
Prospectus Supplement will describe any material contractual restrictions on
dividend payments. Such Prospectus Supplement will also describe any material
United States federal income tax considerations applicable to the Preferred
Stock.
 
NO OTHER RIGHTS
 
    The shares of a series of Preferred Stock will not have any preferences,
voting powers or relative, participating, optional or other special rights
except as set forth above or in the applicable Prospectus Supplement, the
Articles of Incorporation or the applicable Certificate of Designation, or as
otherwise required by law.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for each series of Preferred Stock will be
designated in the applicable Prospectus Supplement.
 
                        DESCRIPTION OF DEPOSITARY SHARES
 
GENERAL
 
    The Company may, at its option, elect to offer fractional shares of the
Preferred Stock of a series, rather than full shares of the Preferred Stock of
such series. In the event such option is exercised, the Company will issue
Depositary Receipts for Depositary Shares, each of which will represent a
fraction (to be set forth in the Prospectus Supplement relating to a particular
series of Preferred Stock) of a share of a particular series of Preferred Stock
as described below.
 
    The shares of any series of Preferred Stock represented by Depositary Shares
will be deposited under a Deposit Agreement (the "Deposit Agreement") among the
Company, a depositary to be named in the applicable Prospectus Supplement (the
"Preferred Stock Depositary") and the holders from time to time of depositary
receipts issued thereunder. Subject to the terms of the Deposit Agreement, each
holder of a Depositary Share will be entitled, in proportion to the applicable
fraction of a share of Preferred Stock represented by such Depositary Share, to
all the rights and preferences of the Preferred Stock represented thereby
(including dividend, voting, redemption, subscription and liquidation rights).
 
    The Depositary Shares will be evidenced by Depositary Receipts issued
pursuant to the Deposit Agreement to those persons purchasing Depositary Shares.
 
    The following description of the terms of the Depositary Shares sets forth
certain general terms and provisions of the Depositary Shares to which any
Prospectus Supplement may relate. The particular terms of the Depositary Shares
offered by any Prospectus Supplement and the extent, if any, to which such
general provisions may apply to the Depositary Shares so offered will be
described in a Prospectus Supplement relating to such Depositary Shares. The
forms of Deposit Agreement and Depositary
 
                                       15
<PAGE>
Receipt will be filed with the Commission as exhibits to a document incorporated
by reference in the Registration Statement prior to the date of any Prospectus
Supplement relating to an offering of the Depositary Shares.
 
    Immediately following the issuance of fractional shares of a series of
Preferred Stock by the Company, the Company will deposit such shares with the
Preferred Stock Depositary, which will then issue and deliver the Depositary
Receipts to the purchasers thereof. Depositary Receipts will only be issued
evidencing whole Depositary Shares. A Depositary Receipt may evidence any number
of whole Depositary Shares.
 
    Pending the preparation of definitive engraved Depositary Receipts, the
Preferred Stock Depositary may, upon the written order of the Company, issue
temporary Depositary Receipts substantially identical to (and entitling the
holders thereof to all the rights pertaining to) the definitive Depositary
Receipts but not in definitive form. Definitive Depositary Receipts will be
prepared thereafter without unreasonable delay, and such temporary Depositary
Receipts will be exchangeable for definitive Depositary Receipts at the
Company's expense.
 
    The following summary of certain provisions which will be included in the
Deposit Agreement with respect to the Depositary Shares does not purport to be
complete and is subject to, and is qualified in its entirety by express
reference to, all the provisions of the Deposit Agreement, including the
definitions therein of certain terms.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
    The Preferred Stock Depositary will distribute all cash dividends or other
cash distributions received in respect of the Preferred Stock represented by the
Depositary Shares to the record holders of the Depositary Shares in proportion
to the number of such Depositary Shares owned by such holders.
 
    In the event of a distribution other than in cash, the Preferred Stock
Depositary will distribute property received by it to the record holders of
Depositary Shares entitled thereto in proportion to the number of Depositary
Shares owned by such holders, unless the Preferred Stock Depositary determines
that such distribution cannot be made proportionately among such holders or that
it is not feasible to make such distributions, in which case the Preferred Stock
Depositary may, with the approval of the Company, adopt such method as it deems
equitable and practicable for the purpose of effecting such distribution,
including the sale (at public or private sale) of the securities or other
property thus received, or any part thereof, at such place or places and upon
such terms as it may deem proper.
 
    The amount distributed in any of the foregoing cases will be reduced by any
amounts required to be withheld by the Company or the Preferred Stock Depositary
on account of taxes or other governmental charges.
 
REDEMPTION OF DEPOSITARY SHARES
 
    If a series of the Preferred Stock underlying the Depositary Shares is
subject to redemption, the Depositary Shares will be redeemed from the proceeds
received by the Preferred Stock Depositary resulting from any redemption, in
whole or in part, of such series of the Preferred Stock held by the Preferred
Stock Depositary. The redemption price per Depositary Share will be the fraction
of the redemption price per share payable with respect to such series of the
Preferred Stock equal to the fraction of a share of such Preferred Stock
represented by a Depositary Share. If the Company redeems shares of a series of
Preferred Stock held by the Preferred Stock Depositary, the Preferred Stock
Depositary will redeem as of the same redemption date the number of Depositary
Shares representing the shares of Preferred Stock so redeemed. If less than all
the Depositary Shares are to be redeemed, the Depositary Shares to be redeemed
will be selected by lot or substantially equivalent method determined by the
Preferred Stock Depositary.
 
    After the date fixed for redemption, the Depositary Shares so called for
redemption will no longer be deemed to be outstanding and all rights of the
holders of the Depositary Shares will cease, except the
 
                                       16
<PAGE>
right to receive the monies payable upon such redemption and any money or other
property to which the holders of such Depositary Shares were entitled upon such
redemption, upon surrender to the Preferred Stock Depositary of the Depositary
Receipts evidencing such Depositary Shares.
 
VOTING THE PREFERRED STOCK
 
    Upon receipt of notice of any meeting at which the holders of any series of
the Preferred Stock are entitled to vote, the Preferred Stock Depositary will
mail the information contained in such notice of meeting to the record holders
of the Depositary Shares relating to such series of Preferred Stock. Each record
holder of such Depositary Shares on the record date (which will be the same date
as the record date for the related series of Preferred Stock) will be entitled
to instruct the Preferred Stock Depositary as to the exercise of the voting
rights pertaining to the number of shares of the series of Preferred Stock
represented by such holder's Depositary Shares. The Preferred Stock Depositary
will endeavor, insofar as practicable, to vote or cause to be voted the number
of shares of the Preferred Stock represented by such Depositary Shares in
accordance with such instructions, provided the Preferred Stock Depositary
receives such instructions sufficiently in advance of such meeting to enable it
to so vote or cause to be voted the shares of Preferred Stock, and the Company
will agree to take all reasonable action that may be deemed necessary by the
Preferred Stock Depositary in order to enable the Preferred Stock Depositary to
do so. The Preferred Stock Depositary will abstain from voting shares of the
Preferred Stock represented by Depositary Shares to the extent it does not
receive specific instructions from the holders of Depositary Shares representing
such Preferred Stock.
 
WITHDRAWAL OF STOCK
 
    Upon a holder's surrender of Depositary Receipts at the corporate trust
office of the Preferred Stock Depositary and upon such holder's payment of the
taxes, charges and fees provided for in the Deposit Agreement and subject to the
terms thereof, the holder of the Depositary Shares evidenced thereby will be
entitled to delivery at such office, to or upon his or her order, of the number
of whole shares of the related series of Preferred Stock and any money or other
property, if any, represented by such Depositary Shares.
 
    Holders of Depositary Shares will be entitled to receive whole shares of the
related series of Preferred Stock, but holders of such whole shares of Preferred
Stock will not thereafter be entitled to deposit such shares of Preferred Stock
with the Preferred Stock Depositary or to receive Depositary Shares therefor. If
the Depositary Receipts delivered by the holder evidence a number of Depositary
Shares in excess of the number of Depositary Shares representing the number of
whole shares of the related series of Preferred Stock to be withdrawn, the
Preferred Stock Depositary will deliver to such holder or upon such holder's
order at the same time a new Depositary Receipt evidencing such excess number of
Depositary Shares.
 
AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT
 
    The form of Depositary Receipt evidencing the Depositary Shares and any
provision of the Deposit Agreement may at any time and from time to time be
amended by agreement between the Company and the Preferred Stock Depositary.
However, any amendment that materially adversely alters the rights of the
holders of Depositary Shares will not be effective unless such amendment has
been approved by the holders of a majority of the Depositary Shares then
outstanding. Every holder of a Depositary Receipt at the time such amendment
becomes effective will be deemed, by continuing to hold such Depositary Receipt,
to be bound by the Deposit Agreement as so amended. Notwithstanding the
foregoing, in no event may any amendment impair the right of any holder of any
Depositary Shares, upon surrender of the Depositary Receipts evidencing such
Depositary Shares and subject to any conditions specified in the Deposit
Agreement, to receive shares of the related series of Preferred Stock and any
money or other property represented thereby, except in order to comply with
mandatory provisions of applicable law. The Deposit Agreement may be terminated
by the Company at any time upon not less than 60 days' prior written notice to
the Preferred Stock Depositary, in which case, on a date that is not later than
30
 
                                       17
<PAGE>
days after the date of such notice, the Preferred Stock Depositary shall deliver
or make available for delivery to holders of Depositary Shares, upon surrender
of the Depositary Receipts evidencing such Depositary Shares, such number of
whole or fractional shares of the related series of Preferred Stock as are
represented by such Depositary Shares. The Deposit Agreement shall automatically
terminate after all outstanding Depositary Shares have been redeemed or there
has been a final distribution in respect of the related series of Preferred
Stock in connection with any liquidation, dissolution or winding-up of the
Company and such distribution has been distributed to the holders of Depositary
Shares.
 
CHARGES OF DEPOSITARY
 
    The Company will pay all transfer and other taxes and the governmental
charges arising solely from the existence of the depositary arrangements. The
Company will pay the charges of the Preferred Stock Depositary, including
charges in connection with the initial deposit of any series of Preferred Stock
represented by Depositary Shares and the initial issuance of the Depositary
Shares and all withdrawals of shares of the related series of Preferred Stock,
except that holders of Depositary Shares will pay other transfer and other taxes
and governmental charges and such other charges as are expressly provided in the
Deposit Agreement to be for their accounts.
 
RESIGNATION AND REMOVAL OF DEPOSITARY
 
    The Preferred Stock Depositary may resign at any time by delivering to the
Company written notice of its election to do so, and the Company may at any time
remove the Depositary, any such resignation or removal to take effect upon the
appointment of a successor Preferred Stock Depositary, which successor Preferred
Stock Depositary must be appointed within 60 days after delivery of the notice
of resignation or removal and must be a bank or trust company having its
principal office in the United States and having a combined capital and surplus
of at least $50,000,000.
 
MISCELLANEOUS
 
    The Preferred Stock Depositary will forward to the holders of Depositary
Shares all reports and communications from the Company that are delivered to the
Preferred Stock Depositary and which the Company is required to furnish to the
holders of the Preferred Stock.
 
    The Preferred Stock Depositary's corporate trust office will be identified
in the applicable Prospectus Supplement. Unless otherwise set forth in the
applicable Prospectus Supplement, the Preferred Stock Depositary will act as
transfer agent and registrar for Depositary Receipts and if shares of a series
of Preferred Stock are redeemable, the Preferred Stock Depositary will act as
redemption agent for the corresponding Depositary Receipts.

                              PLAN OF DISTRIBUTION
 
    The Company 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 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.
 
    The distribution of the Securities may be effected from time to time in one
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.
 
                                       21
<PAGE>
    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, may be entitled to indemnification by the Company against
certain civil liabilities under the Securities Act. Underwriters, dealers and
agents may be customers of, engage in transactions with or perform services for,
the Company in the ordinary course of business.
 
    Offers to purchase Securities may be solicited, and sales thereof may be
made, by the Company directly to institutional investors or others, who may be
deemed to be underwriters within the meaning of the Securities Act with respect
to any resales thereof. The terms of any such offer will be set forth in the
applicable Prospectus Supplement relating thereto.
 
    If so indicated in the applicable Prospectus Supplement, the Company will
authorize underwriters or other agents of the Company to solicit offers by
certain institutional investors to purchase Securities from the Company pursuant
to contracts providing for payment and delivery at a future date. Institutional
investors with which such contracts may be made include commercial and savings
banks, insurance companies, pension funds, investment companies, educational and
charitable institutions and others, but in all cases such purchasers must be
approved by the Company. 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 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
effected at any time and from time to time. Upon any such sale of Securities,
the respective holders thereof and any broker, dealer or underwriter
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 shares, 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.
 
    The anticipated date of delivery of Securities will be set forth in the
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
market for any of the Securities.

    Certain legal matters will be passed upon for the Company by Wolf, Block,

of Nevada law, by Peter C. Walsh, Assistant General Counsel of the Company. Mr.
