                         INTEREST PAYABLE     AND
                              --------------------
 
    Six Flags Entertainment Corporation (the "Company" or "SFEC") is offering
$170,000,000 (the "Offering") in aggregate principal amount of its   % Senior
Notes due     (the "SFEC Senior Notes"). The SFEC Senior Notes will be
guaranteed (the "Guarantee") on an unsecured subordinated basis by Premier Parks
Inc. (collectively with its predecessor, "Premier"), which, following the Six
Flags Acquisition (as defined), will own 100% of the capital stock of the
Company. The SFEC Senior Notes will mature on           , 2008.
 
    Interest on the SFEC Senior Notes will be payable semi-annually in arrears
on             and             of each year, commencing on             , 1998.
The net proceeds of the Offering, together with certain other funds, will be
deposited in escrow to repay in full at or prior to maturity, the Company's Zero
Coupon Senior Notes due 1999 ("SFEC Zero Coupon Senior Notes"). See "Description
of Notes--Escrow of Proceeds." The SFEC Senior Notes will be redeemable at the
option of the Company, in whole or in part, at any time on or after
            , 2003, at the redemption prices set forth herein, plus accrued and
unpaid interest thereon to the date of redemption. In addition, prior to
            , 2001, the Company may redeem up to 35% of the original aggregate
principal amount of the SFEC Senior Notes at    % of the principal amount
thereof to the redemption date with the net cash proceeds of one or more Public
Equity Offerings (as defined) by, or Strategic Equity Investments (as defined)
in, (i) the Company or (ii) Premier to the extent the net cash proceeds thereof
are contributed to the Company as a capital contribution to the common equity of
the Company; provided that at least 65% of the aggregate principal amount of the
SFEC Senior Notes originally issued remains outstanding immediately after the
occurrence of each such redemption.
 
    Upon the occurrence of a Change of Control (as defined), each holder of the
SFEC Senior Notes will have the right to require the Company to purchase all or
any part of such holder's SFEC Senior Notes at a purchase price equal to 101% of
the aggregate principal amount thereof, plus accrued and unpaid interest to the
date of purchase. See "Description of Notes."
 
    Premier's obligations under the Guarantee will be subordinated to all
indebtedness of and other liabilities of Premier and effectively subordinated to
all indebtedness of and other liabilities of Premier's subsidiaries including
borrowings under the Premier Credit Facility (as defined), indebtedness
outstanding under the Old Premier Notes and the New Premier Notes (each as
defined), and Premier's obligations under the Subordinate Indemnity Agreement
(as defined). As of December 31, 1997, after giving pro forma effect to the Six
Flags Transactions and the Walibi Acquisition (each as defined), Premier and its
subsidiaries would have had approximately $      million of indebtedness
(including indebtedness outstanding under the SFEC Senior Notes) and $
million of other obligations outstanding. See "Prospectus Summary--Premier Parks
Inc." and "Description of the Six Flags Agreement."
 
    All of the operations of the Company are conducted through its subsidiaries,
and none of the Company's subsidiaries will guarantee the Company's obligations
under the SFEC Senior Notes. Accordingly, the SFEC Senior Notes will be
effectively subordinated to all indebtedness and other liabilities of such
subsidiaries, including borrowings under the Six Flags Credit Facility and
indebtedness outstanding under the SFTP Senior Subordinated Notes (each as
defined). As of December 28, 1997, after giving pro forma effect to the Six
Flags Transactions, the Company would have had approximately $      million of
indebtedness outstanding and the Company's subsidiaries would have had
approximately $      million of indebtedness outstanding and approximately
$      million of other outstanding liabilities. See "Capitalization" and
"Description of Other Company Indebtedness."
 
    Concurrently with the Offering, Premier is publicly offering in the U.S. and
internationally $500.0 million of its Common Stock, par value $0.05 per share
(the "Common Stock"), and depository receipts representing $200.0 million of its
  % Convertible Exchangeable Preferred Stock (the "Mandatorily Convertible
Preferred Stock"). In addition, Premier is offering $280.0 million aggregate
principal amount of its     % Senior Notes (the "Premier Senior Notes") due 2008
(the "Premier Senior Notes Offering") and $    million aggregate principal
amount at maturity of its     % Senior Discount Notes, (the "Premier Discount
Notes" and, together with the Premier Senior Notes, the "New Premier Notes") due
2008 (the "Premier Discount Notes Offering" and, together with the Premier
Senior Notes Offering, the "Premier Notes Offering"). The closing of the
Offering is conditioned upon the closing of the Premier Notes Offering, the
offerings of Common Stock (the "Common Stock Offering") and Mandatorily
Convertible Preferred Stock (the "Convertible Preferred Stock Offering," and,
together with the Premier Notes Offering, and the Common Stock Offering, the
"Concurrent Offerings") and the closing of each of the Six Flags Transactions.

                                  THE COMPANY
 
    Six Flags is the largest regional theme park company, and the second largest
theme park operator, in the world, based on 1997 attendance. Six Flags operates
eight regional theme parks, as well as three separately gated water parks and a
wildlife safari park (each of which is located near one of the theme parks). The
Six Flags Parks are located in six of the ten largest metropolitan areas in the
country: New York, Philadelphia, Los Angeles, Chicago, Atlanta and Dallas. Upon
consummation of the Six Flags Transactions, SFEC will transfer its interests in
the Co-Venture Parks (as defined) to Premier. The Company estimates that    % of
the U.S. population lives within a 100-mile radius of the Six Flags Parks.
During 1997, the Six Flags Parks drew, in the aggregate, approximately    % of
their patrons from within a 100-mile radius. During that year, Six Flags'
attendance, revenue and earnings before interest, taxes, depreciation and
amortization ("EBITDA") totaled approximately 22.3 million, $708.7 million and
$164.1 million, respectively.
 
    Six Flags, including its predecessors, has operated regional theme parks
under the Six Flags name for over thirty years. As a result, Six Flags has
established a nationally-recognized brand name. Since 1991, Six Flags has used
certain Warner Bros. and DC Comics characters to market its parks and to provide
an enhanced family entertainment experience. These characters include BUGS
BUNNY, DAFFY DUCK, TWEETY BIRD, YOSEMITE SAM, BATMAN, SUPERMAN and others. The
Company utilizes these characters in marketing its parks, in theming revenue
outlets and in selling character merchandise within the parks. The Company
believes that its extensive use of the Warner Bros. and DC Comics characters
promotes attendance, supports higher ticket prices, increases lengths-of-stay
and enhances in-park spending.
 
    The Six Flags Parks are individually themed and provide a complete
family-oriented entertainment experience. The Six Flags Parks generally offer a
broad selection of state-of-the-art and traditional thrill
 
                                       4
<PAGE>
rides, water attractions, themed areas, concerts and shows, restaurants, game
venues and merchandise outlets. In the aggregate, the Six Flags Parks offer more
than 300 rides, including [57] roller coasters, making Six Flags one of the
leading providers of "thrill rides" in the industry.
 
    Premier believes that the Company's parks benefit from limited direct
competition. The combination of limited supply of real estate appropriate for
theme park development, high initial capital investment, long development
lead-time and zoning restrictions provides each of the parks with a significant
degree of protection from competitive new theme park openings. Based on its
knowledge of the development of other theme parks in the United States,
Premier's management estimates that it would cost at least $200 million and
would take a minimum of two years to construct a new regional theme park
comparable to the Company's largest parks.
 
    According to AMUSEMENT BUSINESS, total North American amusement/theme park
attendance in 1997 was approximately 270 million, compared to    million in 1994
(the first year in which such information is available from that publication),
representing a compound annual growth rate of    %. Total attendance for the 40
largest parks in North America was 154.7 million in 1997, compared to
million in 1992, representing a compound annual growth rate of    %. Premier
believes that this growth reflects two trends: (i) demographic growth in the
5-24 year old age group, which is expected to continue through 2010; and (ii) an
increasing emphasis on family-oriented leisure and recreation activities.
 
OPERATING STRATEGY
 
    Premier believes there are substantial opportunities for continued internal
growth at the Six Flags Parks. Upon consummation of the Six Flags Acquisition,
Premier's management intends to apply its operating strategy to pursue growth
and margin expansion at Six Flags. Premier's operating strategy seeks to
increase revenues by increasing per capita spending, while also reducing
corporate overhead and improving cost controls at the Six Flags Parks. The
primary elements of this operating strategy applicable to the Six Flags Parks
are: (i) periodically adding rides and attractions and improving overall park
quality; (ii) enhancing marketing and sponsorship programs; (iii) adding and
enhancing restaurants and merchandise and other revenue outlets; and (iv) adding
special events. This approach is designed to exploit the operating leverage
inherent in the theme park business. Once parks achieve certain critical
attendance levels, operating cash flow margins increase because revenue growth
through incremental attendance gains and increased in-park spending is not
offset by a comparable increase in operating expenses, since a large portion of
such expenses is relatively fixed during any given year.
 
    The Six Flags Parks generally enjoy significant market penetration. Thus,
although Premier plans to make targeted capital expenditures at these parks to
increase attendance and per capita spending levels, it expects to increase
significantly the EBITDA of these parks primarily through reduction in operating
expenses. First, and most importantly, Premier believes that it can
substantially reduce Six Flags' corporate overhead and other corporate-level
expenses. Second, Premier expects to achieve significant reduction in park-level
operating expenses. Third, by virtue of economies of scale, Premier believes
that operating efficiencies in areas such as marketing, insurance, promotion,
purchasing and other expenses can be realized. Finally, Premier believes that
its increased size following the Six Flags Acquisition will enable it to achieve
savings in capital expenditures.
 
EXPANSION STRATEGY
 
    Premier may expand in the future certain of the Six Flags Parks by adding
complementary attractions, such as campgrounds, lodging facilities, new water
parks and concert venues. For example, Six Flags owns over 1,500 undeveloped
acres adjacent to Six Flags Great Adventure (located between New York City and
Philadelphia) suitable for such purposes. Additional acreage suitable for
development exists at several other Six Flags Parks.
 
ACQUISITION STRATEGY
 
    The U.S. regional theme park industry is highly fragmented with over 150
parks owned by over 100 operators. Premier believes that there are numerous
acquisition opportunities, both in the U.S. and
 
                                       5
<PAGE>
abroad, that can expand its business. Since 1989, Premier has pursued a strategy
of acquiring and improving regional theme parks. Premier's primary target for
acquisitions continues to be regional parks with attendance between 300,000 and
1.5 million annually, but will also consider acquisitions of larger parks or
chains. Although it anticipates making acquisitions primarily through Premier
Operations (as defined), Premier may also make acquisitions of additional parks
through Six Flags.
 
                               PREMIER PARKS INC.
 
    After giving effect to the Six Flags Acquisition, Premier will be the
largest regional theme park operator, and the second largest theme park company,
in the world, based on 1997 attendance of approximately 37 million. Including
the Six Flags Parks and the Walibi Parks, it will operate 31 regional parks,
including 15 of the 50 largest theme parks in the U.S., based on 1997
attendance. On a pro forma basis, Premier's total revenue and EBITDA for the
year ended December 31, 1997 would have been approximately $  million and
$  million, respectively.
 
    The Premier Parks consist of nine regional theme parks (six of which include
a water park component) and four water parks located acrosss the United States,
as well as six regional theme parks located in Europe and scheduled to be
acquired in March 1998 in the Walibi Acquisition. During the 1997 operating
season, the 11 parks then owned by Premier drew, on average, approximately 82%
of their patrons from within a 100-mile radius, with approximately 36.1% of
visitors utilizing group and other pre-sold tickets and approximately 20.6%
utilizing season passes. During the year ended December 31, 1997, the 11 parks
owned by the Company during the 1997 operating season achieved same park growth
in attendance, revenue and park-level operating cash flow (representing all park
operating revenues and expenses without depreciation and amortization or
allocation of corporate overhead or interest expense) of     %,     % and     %,
respectively, as compared to the comparable period of 1996.
 
    Premier believes that, by virtue of the Six Flags Acquisition, a number of
the existing Premier Parks have the potential over the next several seasons to
accelerate their rate of growth. Recent attendance levels at the Six Flags Parks
(between 1.7 millon and 3.6 million in 1997) have been substantially higher than
the annual attendance at the largest Premier Parks (between 1.0 million and 1.5
million during that year). Premier management believes that a number of the
existing Premier Parks, many of which are located in or near major metropolitan
areas, can accelerate their market penetration and the expansion of their
geographic market by their use of the Six Flags brand name, aggressive marketing
campaigns featuring the animated characters licensed from Warner Bros. and D.C.
Comics, as well as continued capital investment in new rides and attractions.
Premier expects to commence general use of the Six Flags brand name and the
licensed characters at the Premier Parks for the 1999 season.
 
    The Company's senior and operating management team has extensive experience
in the theme park industry. Premier's six senior executive officers have over
150 years aggregate experience in the industry and its nine general managers
(prior to the Six Flags Acquisition) have an aggregate of approximately 200
years experience in the industry, including approximately 80 years at the
Premier Parks. A number of Premier's executives and operating personnel have
experience at the Six Flags Parks.
 
    Premier was incorporated in 1981 as The Tierco Group Inc. In 1994, Premier
changed its name to Premier Parks Inc. Premier's principal executive offices
are, and following the Six Flags Transactions, the Company's principal executive
offices will be, located at 11501 Northeast Expressway, Oklahoma City, Oklahoma
73131, (405) 475-2500 and at 122 East 42nd Street, New York, New York 10168,
(212) 599-4690.

                                    funds, to provide for the repayment in full of the SFEC
                                    Zero Coupon Senior Notes. See "Use of Proceeds."
 
Escrow............................  The net proceeds of the Offering will be used to
                                    purchase a portfolio of Government Securities that will
                                    be held in escrow to provide for the payment in full of
                                    the SFEC Zero Coupon Notes and, under certain
                                    circumstances, as security for the repayment of
                                    principal of the SFEC Senior Notes. See "Description of
                                    Notes."
 
Ranking of Notes..................  SFEC Senior Notes will be general unsecured obligations
                                    of the Company, ranking PARI PASSU in right of payment
                                    with the SFEC Zero Coupon Senior Notes (until repaid)
                                    and all future senior indebtedness of the Company, and
                                    senior in right of payment to all future subordinated
                                    indebtedness of the Company. The Company is a holding
                                    company whose only significant asset is the capital
                                    stock of its subsidiaries. The SFEC Senior Notes will
                                    not be guaranteed by such subsidiaries. Accordingly, the
                                    SFEC Senior Notes will be structurally subordinated to
                                    all indebtedness and other liabilities (including trade
                                    payables) of the Company's subsidiaries, including all
                                    borrowings under the Six Flags Credit Facility and all
                                    indebtedness outstanding under the Six Flags Indentures
                                    (as defined). As of December 28, 1997, Six Flags had
                                    approximately $         million of indebtedness
                                    outstanding and approximately $         million of other
                                    outstanding liabilities.

Guarantee.........................  Premier's obligations under the Guarantee will be
                                    subordinated to all indebtedness of and other
                                    liabilities of Premier Parks Inc. and effectively

                                    of its subsidiaries, including borrowings under the
                                    Premier Credit Facility, indebtedness outstanding under
                                    the Old Premier Notes and the New Premier Notes, and
                                    Premier's obligations under the Subordinate Indemnity
                                    Agreement. As of December 31, 1997, after giving pro
                                    forma effect to the Six Flags Transactions and the
                                    Walibi Acquisition, Premier would have had approximately
                                    $    million of indebtedness (including indebtedness
                                    outstanding under the SFEC Senior Notes) and $
                                    million of other obligations outstanding.

                                    of the SFEC Senior Notes will have the right to require
                                    the Company to repurchase such holders' SFEC Senior
                                    Notes, in whole or in part, at a price equal to 101% of
                                    the aggregate principal amount thereof, plus accrued and
                                    unpaid interest to the date of purchase. There can be no
                                    assurance that the Company or Premier will be able to
                                    raise sufficient funds to meet this obligation should it
                                    arise. See "Risk Factors--Risks Associated with a Change
                                    of Control" and "Description of Notes--Repurchase at the

                                    ability of the Company and its subsidiaries to (i) incur
                                    additional indebtedness and issue preferred stock, (ii)

 (1) Prior to the Six Flags Acquisition, the Company, through two subsidiaries,
     was the general partner in two theme park limited partnerships (the
     "Co-Venture Partnerships"). For the years presented the Company accounted
     for the parks as co-ventures, i.e., the revenues and expenses (excluding
     partnership depreciation) are included in the Company's consolidated
     statements of operations and the net amounts distributed to the limited
     partners are deducted as expenses. Except for the limited partnership units
     purchased pursuant to the tender offer, the Company has no rights or title
     to the Co-Venture Parks' assets or to the proceeds from any sale of the
     Co-Venture Parks' assets or liabilities. Accordingly, the Company's
     consolidated balance sheets do not include any of the Co-Venture Parks'
     assets. The investment in Co-Venture Parks included in the consolidated
     balance sheets represents (i) the Company's interest in the estimated
     future cash flows from the operations of the Co-Venture Parks and is
     amortized over the life of the partnership agreements, and (ii) the value
     of Limited Partnership units purchased pursuant to the SFOG tender offer.
     The co-venture parks contributed revenues of $176.8 million, $152.0 million
 
                                         (FOOTNOTES CONTINUED ON FOLLOWING PAGE)

     and $160.6 million to the Company in the fiscal years 1997, 1996 and 1995,
     respectively. In connection with the Six Flags Acquisition, the Company is
     transferring its interests in the Co-Venture Parks to Premier. The pro
     forma statement of operations data for the year ended December 28, 1997
     gives effect to the transfer of such interests as if it occurred on
     December 30, 1996.
 
 (2) Income from operations is revenue less operating, general and
     administrative expenses, costs of products sold and depreciation and
     amortization.
 
 (3) EBITDA is defined as earnings before interest expense, net, income tax
     expense (benefit), depreciation and amortization and minority interest. The
     Company has included information concerning EBITDA because it is used by
     certain investors as a measure of the Company's ability to service and/or
     incur debt. EBITDA is not required by generally accepted accounting
     principles ("GAAP") and should not be considered in isolation or as an
     alternative to net income, net cash provided by operating, investing and
     financing activities or other financial data prepared in accordance with
     GAAP or as an indicator of the Company's operating performance. This
     information should be read in conjunction with the Statements of Cash Flows
     contained in the financial statements included elsewhere herein.
 
 (4) During each of the years ended December 28, 1997, December 29, 1996,
     December 31 1995, January 1, 1995 and December 26, 1993, the Company's net
     cash used in investing activities was approximately $149.7 million, $81.2
     million, $93.9 million, $43.8 million and $41.6 million, respectively.
     During these periods, net cash provided (used) in financing activities was
     approximately $10.6 million, $(52.2) million, $10.6 million, $(55.6)
     million and $(73.2) million, respectively.
 
 (5) Does not include amount expended ($62.7 million) by the Company to purchase
     interests in the limited partners of the Co-Venture Partnerships.
 
 (6) For the purpose of determining the ratio of earnings to fixed charges and
     the ratio of earnings to combined fixed charges and preferred stock
     dividends, earnings consist of income (loss) before income taxes and fixed
     charges. Fixed charges consist of interest expense net of interest income,
     amortization of deferred financing costs and discount or premium relating
     to indebtedness, and the portion (approximately one-third) of rental
     expense that management believes represents the interest component of rent
     expense. Preferred stock dividend requirements have been increased to an
     amount representing the before tax earnings which would have been required
     to cover such dividend requirements. On a pro forma basis, for the year
     ended December 28, 1997, the Company's earnings were insufficient to cover
     fixed charges and combined fixed charges and preferred stock dividends by
     $    and $    , respectively.
 
 (7) The pro forma balance sheet data give effect to the Six Flags Acquisition,
     the Offerings, the related financings, and the transfer of the Company's
     interests in the Co-Venture Parks to Premier as if they had occurred on
     December 28, 1997.

                                  RISK FACTORS
 
    PRIOR TO MAKING AN INVESTMENT IN THE SECURITIES OFFERED HEREBY, PROSPECTIVE
INVESTORS SHOULD CAREFULLY CONSIDER, TOGETHER WITH THE OTHER MATTERS REFERRED TO
IN THIS PROSPECTUS, THE FOLLOWING RISK FACTORS:
 
RISKS ASSOCIATED WITH SUBSTANTIAL INDEBTEDNESS
 
    The Company is, and following the Six Flags Transactions, Premier will be,
highly leveraged. On a pro forma basis, as of December 28, 1997, the Company had
total outstanding indebtedness of approximately $   million, including: (i) $
million under the Six Flags Credit Facility, (ii) $269.9 million in accreted
value at that date of SFTP Senior Subordinated Notes ($285.0 million principal
amount at maturity in 2005), and (iii) $170.0 million under the SFEC Senior
Notes. Indebtedness at that date also included $160.1 million accreted value of
SFEC Zero Coupon Senior Notes, which will be repaid with the proceeds of the
SFEC Senior Notes together with certain additional funds. Until such repayment,
the SFEC Zero Coupon Senior Notes will rank PARI PASSU with the SFEC Senior
Notes. On a pro forma basis, for the year ended December 28, 1997, the Company's
earnings would have been insufficient to cover its combined fixed charges by
approximately $   million. In addition the indentures relating to the SFEC
Senior Notes and the SFTP Senior Subordinated Notes (the "Six Flags Indentures")
and the Six Flags Credit Facility permit the Company to incur additional
indebtedness under certain circumstances. See "Description of Other Company
Indebtedness" and "Description of Notes--Certain Covenants."
 
    In addition to the Company's indebtedness, following the Six Flags
Transactions, on a pro forma basis, as of December 31, 1997, Premier had
outstanding indebtedness of approximately $    million, including: (i)
$   million of Six Flags indebtedness, as described above; (ii) $250.0 million
in accreted value at that date of the Premier Discount Notes ($    million
principal amount at maturity in 2008); (iii) $280.0 million in aggregate
principal amount of Premier Senior Notes; (iv) $125.0 million in aggregate
principal amount of Premier Operations' 9 3/4% Senior Notes due 2007 (the "1997
Premier Notes"); (v) $90.0 million in aggregate principal amount of Premier
Operations' 12% Senior Notes due 2003 (the "1995 Premier Notes," together with
the 1997 Premier Notes, the "Old Premier Notes" and collectively with the SFEC
Senior Notes, the New Premier Notes and the SFTP Senior Subordinated Notes, the
"Senior Notes"); and (vi) $         million in outstanding borrowings under the
Premier Credit Facility. On a pro forma basis, as of December 31, 1997, Premier
would have had stockholders' equity of approximately $         million. In
addition, the annual dividends (which are payable in cash, in the case of the
Seller Preferred Stock, or in cash, or by issuance of shares of Common Stock, at
the option of the Company, in the case of the Mandatorily Convertible Preferred
Stock) on the Convertible Preferred Stock aggregate $         , and the Seller
Preferred Stock is mandatorily redeemable in 2010 (if not earlier redeemed or
converted). On a pro forma basis, for the year ended December 31, 1997,
Premier's earnings would have been insufficient to cover its combined fixed
charges and preferred stock dividends by approximately $         million. In
addition, the indentures relating to the Senior Notes (the "Indentures") permit
Premier to incur additional indebtedness under certain circumstances. See
"Capitalization," "Selected Historical and Pro Forma Financial and Operating
Data," "Description of Other Company Indebtedness," "Description of
Notes--Certain Covenants" and "Description of Premier Indebtedness."
 
    By reason of the Six Flags Acquisition, SFTP will be required to offer to
repurchase the SFTP Senior Subordinated Notes at a price equal to 101% of their
accreted amount (approximately $287.9 million at June 15, 1998). On February   ,
1998, the last reported sales price of these Notes was equivalent to    % of
their accreted amount. SFTP has not entered into any standby arrangement to
finance the purchase of such notes and there can be no assurance that SFTP would
be able to obtain such financing in the event that it were to become necessary.
 
    In addition to its obligations under its outstanding indebtedness and
preferred stock, Premier, along with the Company and SFTP, has guaranteed
certain obligations of the Co-Venture Parks (as defined below) to (i) make
minimum annual distributions of approximately $46.2 million (subject to cost of
living adjustments) to its partners in two Six Flags Parks, Six Flags Over
Georgia and Six Flags Over Texas (the
 
                                       14
<PAGE>
"Co-Venture Parks") and (ii) make minimum capital expenditures at each of the
Co-Venture Parks during rolling five-year periods, based generally on 6% of such
park's revenues. Cash flow from operations at the Co-Venture Parks will be used
to satisfy these requirements first, before any funds are required from Premier,
the Company or SFTP. Premier has also agreed to purchase a maximum number of 5%
per year (accumulating to the extent not purchased in any given year) of the
total limited partnership units of these partnerships (the "Co-Venture
Partnerships") (to the extent tendered by the unit holders) and the Company and
SFTP have guaranteed these obligations. The agreed price for these purchases is
based on a valuation for each respective Co-Venture Park equal to the greater of
(i) a value derived by multiplying its weighted-average four year EBITDA by a
specified multiple (8.0 in the case of the Georgia park and 8.5 in the case of
the Texas park) or (ii) $250.0 million in the case of the Georgia park and
$374.8 million in the case of the Texas park. Premier's obligations with respect
to Six Flags Over Georgia and Six Flags Over Texas will continue until 2026 and
2027, respectively. As Premier purchases units, it will be entitled to the
minimum distribution and other distributions attributable to such units, unless
it is then in default under the Subordinate Indemnity Agreement. See
"Description of Six Flags Agreement." Premier estimates that its maximum unit
purchase obligation for 1998, when purchases are required only for the Georgia
park, will aggregate approximately $13 million (approximately $32 million for
1999, when purchases for both partnerships are required) and its minimum capital
expenditures for 1998 at these parks will total approximately $18 million. See
"Business--Description of Parks--Six Flags Over Georgia" and "--Six Flags Over
Texas; Six Flags Hurricane Harbor." In addition, Premier has agreed to invest
approximately $37.7 million to expand the Walibi Parks over three years,
commencing 1999.
 
    The Company's ability to make scheduled payments on, or to refinance, its
indebtedness (including the SFEC Senior Notes), or to fund planned capital
expenditures, and Premier's ability to make scheduled payments on, or to
refinance, its indebtedness (including the Guarantee), or to fund planned
capital expenditures and its obligations under the arrangements relating to the
Co-Venture Parks, will depend on their respective future performances, which, to
a certain extent, are subject to general economic, financial, weather,
competitive and other factors that are beyond their control. The Company
believes that cash flow from operations, available cash and available borrowings
under the Six Flags Credit Facility will be adequate to meet the Company's
future liquidity needs, including anticipated requirements for working capital,
capital expenditures and scheduled debt payments, for at least the next several
years. Premier believes that cash flow from operations and available cash,
available borrowings under the Credit Facilities and the net proceeds of the
Offerings (to the extent not used in connection with the Six Flags Acquisition)
will be adequate to meet Premier's future liquidity needs, including anticipated
requirements for working capital, capital expenditures, scheduled debt and
preferred stock payments and its obligations under arrangements relating to the
Co-Venture Parks, for at least the next several years. However, the Company
and/or Premier may need to refinance all or a portion of their existing debt on
or prior to maturity or to obtain additional financing. There can be no
assurance that the Company's business will generate sufficient cash flow from
operations or that future borrowings will be available under the Six Flags
Credit Facility in an amount sufficient to enable the Company to service its
indebtedness or enable it to fund its other liquidity needs. Similarly, there
can be no assurance that Premier's business will generate sufficient cash flow
from operations or that future borrowings will be available under the Credit
Facilities in an amount sufficient to enable Premier to service its indebtedness
or enable it to fund its other liquidity needs. In addition, there can be no
assurance that the Company and/or Premier will be able to effect any such
refinancing on commercially reasonable terms or at all. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity, Capital Commitments and Resources."
 
    The degree to which Premier and the Company will be leveraged following the
Six Flags Transactions could have important consequences to the holders of the
SFEC Senior Notes, including, but not limited to: (i) making it more difficult
for Premier and the Company to satisfy its obligations, (ii) increasing
Premier's and the Company's vulnerability to general adverse economic and
industry conditions, (iii) limiting Premier's and the Company's ability to
obtain additional financing to fund future working capital, capital
expenditures, acquisitions and other general corporate requirements, (iv)
requiring the dedication of a
 
                                       15
<PAGE>
substantial portion of Premier's and the Company's cash flow from operations to
the payment of principal of, and interest on, its indebtedness, thereby reducing
the availability of such cash flow to fund working capital, capital
expenditures, acquisitions or other general corporate purposes, (v) limiting
Premier's and the Company's flexibility in planning for, or reacting to, changes
in its business and the industry, and (vi) placing Premier and the Company at a
competitive disadvantage vis-a-vis less leveraged competitors. In addition, the
Indentures and the Credit Facilities will contain financial and other
restrictive covenants that will limit the ability of Premier and the Company to,
among other things, borrow additional funds. Failure by Premier and the Company
to comply with such covenants could result in an event of default which, if not
cured or waived, could have a material adverse effect on the Company. In
addition, the degree to which Premier and the Company are leveraged could
prevent them from repurchasing all of the SFEC Senior Notes tendered to them
upon the occurrence of a Change of Control. See "Description of Other Company
Indebtedness," "Description of Notes--Repurchase at Option of Holders--Change of
Control" and "Description of Premier Indebtedness."
 
HOLDING COMPANY STRUCTURE; LIMITATIONS ON ACCESS TO CASH FLOW OF SUBSIDIARIES
 
    The Company has no operations of its own and derives all of its revenue from
its subsidiaries. Premier is also a holding company. Therefore, the Company's
ability to pay its obligations (including debt service on the SFEC Senior Notes)
and Premier's ability to pay its obligations (including the Guarantee), when due
is entirely dependent upon the receipt of sufficient funds from their respective
direct and indirect subsidiaries.
 
    Under the terms of the Six Flags Indentures and the Six Flags Credit
Facility, the payment of dividends by SFEC and SFTP are subject to certain
specified financial tests which will significantly restrict their ability to pay
dividends or make other distributions. However, SFTP is permitted to pay
dividends to the Company to fund interest payments on the SFEC Senior Notes
without regard to these financial tests. See "Description of Other Indebtedness"
for summary of the terms of the dividend restrictions. The terms of the SFEC
Senior Notes will permit the Company's subsidiaries to incur additional
indebtedness, the terms of which could further limit the payment of dividends or
the making of other distributions by such subsidiaries. On a pro forma basis, as
of December 28, 1997, SFTP would have had the ability to pay dividends or make
other restricted payments to the Company in an aggregate amount of approximately
$         million. There can be no assurance that dividends, distributions or
loans to the Company from its subsidiaries will be sufficient to fund its
obligations.
 
    Under the terms of the Indentures and the Credit Facilities, the payment of
dividends by Premier Operations, SFEC and SFTP are subject to certain specified
financial tests which will significantly restrict their ability to pay dividends
or make other distributions. See "Description of Other Company Indebtedness" and
"Description of Premier Indebtedness" for summary of the terms of the dividend
restrictions. The terms of the New Premier Notes and the Mandatorily Convertible
Preferred Stock will permit Premier's subsidiaries to incur additional
indebtedness, the terms of which could further limit the payment of dividends or
the making of other distributions by such subsidiaries. On a pro forma basis, as
of December 31, 1997, Premier Operations and SFEC would have had the ability to
pay dividends or make other restricted payments to Premier in an aggregate
amount of approximately $   million. There can be no assurance that dividends,
distributions or loans to Premier from its subsidiaries will be sufficient to
fund its obligations.
 
    The SFEC Senior Notes will be effectively subordinated to all indebtedness
and other obligations of the Company's subsidiaries. On a pro forma basis, as of
December 28, 1997, the aggregate amount of indebtedness and other obligations of
the Company's subsidiaries (including trade payables) that would effectively
rank senior in right of payment to the obligations of the Company under the SFEC
Senior Notes would have been approximately $    million (in addition,
approximately $    million would have been available for additional borrowings
under the Six Flags Credit Facility). If any indebtedness of any of the
Company's subsidiaries were to be accelerated, there would be no assurance that
the assets of any such
 
                                       16
<PAGE>
subsidiary would be sufficient to repay such indebtedness. The Company's rights
to participate in the distribution of the assets of its operating subsidiaries
upon a liquidation or reorganization of such companies will be subject to the
prior claims of their respective creditors.
 
    The Guarantee will be subordinated to all indebtedness and other obligations
of Premier Parks Inc. and effectively subordinated to all indebtedness and other
obligations of Premier's subsidiaries, including the Senior Notes, borrowings
under the credit facilities and Premier's obligations under the Subordinate
Indemnity Agreement. On a pro forma basis, as of December 31, 1997, the
aggregate amount of indebtedness and other obligations of Premier (including
trade payables and the SFEC Senior Notes) that would rank or effectively rank
senior in right of payment to the obligations of Premier under the Guarantee
would have been approximately $   million (in addition, approximately
$   million would have been available for additional borrowings under the Credit
Facilities). If any indebtedness of any of Premier's subsidiaries were to be
accelerated, there would be no assurance that the assets of any such subsidiary
would be sufficient to repay such indebtedness. Premier's rights to participate
in the distribution of the assets of its operating subsidiaries upon a
liquidation or reorganization of such companies will be subject to the prior
claims of their respective creditors.
 
RESTRICTIVE DEBT COVENANTS
 
    The Credit Facilities contain a number of significant covenants that, among
other things, restrict the ability of the Company and other operating
subsidiaries of Premier to dispose of assets, incur additional indebtedness, pay
cash dividends, create liens on assets, make investments or acquisitions, engage
in mergers or consolidations, make capital expenditures, engage in certain
transactions with affiliates or redeem or repurchase the indebtedness of such
subsidiaries. In addition, under the Credit Facilities, Premier Operations and
SFTP are each required to comply with specified financial ratios and tests,
including interest expense, fixed charges, debt service and total debt coverage
ratios. The Indentures also contain a series of restrictive covenants.
 
    The Company and Premier are currently in compliance with the respective
covenants and restrictions contained in the Credit Facilities and the
Indentures. However, their ability to continue to comply with the respective
financial tests and ratios in the Credit Facilities may be affected by events
beyond their control, including prevailing economic, financial, weather and
industry conditions. The breach of any such financial covenant could result in
the termination of the Credit Facilities (and the acceleration of the maturity
of all amounts outstanding thereunder) and, by virtue of cross-default and
cross-acceleration provisions, the acceleration of the maturity of other
indebtedness of the Company and/or Premier, including the SFEC Senior Notes.
 
    In addition, under the terms of the Subordinate Indemnity Agreement to be
entered into in connection with the Six Flags Transactions (the "Subordinate
Indemnity Agreement") (which lasts until 2028), without the consent of Time
Warner Inc. (collectively with its affiliates, "Time Warner"), Premier cannot
incur indebtedness at SFEC or any of its subsidiaries that is secured by any
assets of Premier, Premier Operations or any of its subsidiaries, or secure any
indebtedness of Premier, Premier Operations or any of its subsidiaries, with any
of the assets of SFEC or any of its subsidiaries. These covenants could inhibit
the ability of Premier to borrow in the future.
 
RISKS OF ACCIDENTS AND DISTURBANCES AT PARKS; EFFECTS OF LOCAL CONDITIONS AND
  EVENTS
 
    Because substantially all of the Company's parks feature "thrill rides,"
attendance at the parks and, consequently, revenues may be adversely affected by
any serious accident or similar occurrence with respect to a ride. Six Flags'
liability insurance policies provide coverage of up to $175.0 million per loss
occurrence and require Six Flags to pay the first $2.0 million per loss
occurrence.
 
    Other local conditions and events can also adversely affect attendance. For
example, in 1994, the Six Flags Magic Mountain park experienced significant
attendance declines and interruptions of business as a result of the Los Angeles
County earthquake centered in Northridge, California. Six Flags Over Georgia
 
                                       17
<PAGE>
experienced attendance declines in 1996 as a result of the 1996 Summer Olympics.
Management believes that the geographic diversity of the Company's theme parks
reduces the effects of such occurrences on the Company's consolidated results.
 
    In addition, in view of the proximity of certain of the Company's parks to
major urban areas and the appeal of the parks to teenagers and young adults, the
Company's parks could experience disturbances that could adversely affect the
image of and attendance levels at its parks. Working together with local police
authorities, the Company has taken certain security-related precautions designed
to prevent disturbances in its parks, but there can be no assurance that it will
be able to prevent any such disturbances.
 
EFFECTS OF INCLEMENT WEATHER; SEASONAL FLUCTUATIONS OF OPERATING RESULTS
 
    Because the great majority of theme parks' attractions are outdoor
activities, attendance at parks and, accordingly, the Company's revenues are
significantly affected by the weather. Additionally, the Company's water parks,
by their nature, are more sensitive to adverse weather than are theme parks.
Unfavorable weekend weather and unusual weather of any kind can adversely affect
park attendance.
 
    The operations of the Company are highly seasonal, with more than 80% of
park attendance occurring in the second and third calendar quarters of each
year. The great majority of the Company's revenue is collected in those quarters
while most expenditures for capital improvements and significant maintenance are
incurred when the parks are closed in the first and fourth quarters.
Accordingly, the Company believes that quarter-to-quarter comparisons of its
results of operations should not be relied upon as an indication of future
performance.
 
HIGHLY COMPETITIVE BUSINESS
 
    The Six Flags Parks compete directly with other theme, water and amusement
parks and indirectly with all other types of recreational facilities and forms
of entertainment within their market areas, including movies, sports attractions
and vacation travel. Accordingly, the Company's business is and will continue to
be subject to factors affecting the recreation and leisure time industries
generally, such as general economic conditions and changes in discretionary
consumer spending habits. Within each park's regional market area, the principal
factors affecting competition include location, price, the uniqueness and
perceived quality of the rides and attractions in a particular park, the
atmosphere and cleanliness of a park and the quality of its food and
entertainment.
 
RISKS ASSOCIATED WITH A CHANGE OF CONTROL
 
    Upon a Change of Control, the Company will be required to offer to
repurchase all outstanding SFEC Senior Notes at 101% of the principal amount
thereof, plus accrued and unpaid interest thereon to the date of purchase.
However, there can be no assurance that sufficient funds will be available at
the time of any Change of Control to make any required repurchases of the SFEC
Senior Notes tendered or that restrictions in the Credit Facilities and the
Indentures will allow the Company to make such required repurchases.
Notwithstanding these provisions, the Company could enter into certain
transactions, including certain recapitalizations, that would not constitute a
Change of Control but would increase the amount of debt outstanding at such
time. See "Description of Notes--Repurchase at Option of Holders."
 
    By virtue of the Six Flags Transactions, SFTP will be required to make an
offer to purchase the SFTP Senior Subordinated Notes. See "--Risks Associated
with Substantial Indebtedness." Warner Bros. can terminate the license agreement
if persons engaged in the movie or television industries or party to a material
judicial proceeding pending against Time Warner obtain control of Premier.
 
    By virtue of the Six Flags Acquisition, certain reserved shares and options
to purchase shares of the Company issued to employees will vest this voting will
result in significant composition expense for the Company in the period in which
consummation of the Six Flags acquisition occurs.
 
                                       18
<PAGE>
ABSENCE OF PUBLIC MARKET
 
    There is no existing trading market for the SFEC Senior Notes. The Company
does not intend to apply for listing of the SFEC Senior Notes on any securities
exchange. The Underwriters have advised the Company that they currently intend
to make a market in the SFEC Senior Notes. However, they are not obligated to do
so and any such market making may be discontinued at any time without notice.
Accordingly, there can be no assurance as to the prices or liquidity of, or
trading markets for, the SFEC Senior Notes. The liquidity of any market for the
SFEC Senior Notes will depend upon the number of holders of SFEC Senior Notes,
the interest of securities dealers in making a market in the SFEC Senior Notes,
and other factors. The absence of an active market for the SFEC Senior Notes
could adversely affect the liquidity of the SFEC Senior Notes. Even if such a
market were to develop, the SFEC Senior Notes could trade at prices that may be
lower than their initial offering price as a result of many factors, including
prevailing interest rates and the Company's operating results and financial
condition at the time. The liquidity of, and trading markets for, the SFEC
Senior Notes may also be adversely affected by general declines in the market
for non-investment grade debt.
 
IMPACT OF YEAR 2000 ISSUE
 
    An issue exists for all companies that rely on computers as the year 2000
approaches. The "Year 2000" problem is the result of the past practice in the
computer industry of using two digits rather than four to identify the
applicable year. This practice will result in incorrect results when computers
perform arithmetic operations, comparisons or data field sorting involving years
later than 1999. The Company has completed plans to ensure year 2000 compliance
and started conversions of applications beginning in 1996. These modifications
and replacements are expected to be completed by January 1999. Costs in
connection with any such modifications are not expected to be material. However,
if such modifications are not completed in a timely manner, the Year 2000
problem may have a material adverse impact on the operations of the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Impact of Year 2000 Issue."

                                USE OF PROCEEDS
 
    The net proceeds to be received by the Company from the Offering, after
deducting estimated underwriting discounts and commissions and estimated
expenses payable by the Company, will be approximately $         million. Net
proceeds from the Offering, together with certain additional funds, will be
deposited in escrow to repay in full at or prior to maturity the SFEC Zero
Coupon Senior Notes. See "Description of Notes--Escrow of Proceeds."
 
    Premier intends to use the net proceeds from the Concurrent Offerings to
fund the $765 million cash portion of the purchase price payable to the Sellers
in the Six Flags Acquisition; to acquire and make improvements at additional
theme parks; to fund improvements and expansion of the Company's parks,
including the parks to be acquired in the Walibi Acquisition and the Six Flags
Parks; and for general corporate purposes, including working capital
requirements. Although Premier has had discussions with respect to several
additional acquisition opportunities, no agreement or understanding with respect
to any future acquisition (other than the Six Flags Acquisition) has been
reached. There can be no assurance that any such additional acquisitions will be
made.
 
    Pending their ultimate use, the portion of net proceeds from the Concurrent
Offerings not used in connection with the Six Flags Acquisition may be invested
in short-term, investment grade, interest bearing securities, certificates of
deposit or direct or guaranteed obligations of the United States.

- ------------------------
 
(1) Prior to the Six Flags Acquisition, the Company, through two subsidiaries,
    was the general partner in two theme park limited partnerships. For the
    years presented, the Company accounted for the parks as co-ventures, i.e.,
    the revenues and expenses (excluding partnership depreciation) are included
    in the Company's consolidated statements of operations and the net amounts
    distributed to the limited partners are deducted as expenses. Except for the
    limited partnership units purchased pursuant to the tender offer, the
    Company has no rights or title to the Co-Venture Parks' assets or to the
    proceeds from any sale of the Co-Venture Park's assets. Accordingly, the
    Company's consolidated balance sheets do not include any of the Co-Venture
    Parks' assets or liabilities. The investment in the Co-Venture Parks
    included in the consolidated balance sheets represents (i) the Company's
    interest in the estimated future cash flows from the operations of the
    Co-Venture Parks and is amortized over the life of the partnership
    agreements, and (ii) the value of Limited Partnership units purchased
    pursuant to the SFOG tender offer. The Co-Venture Parks contributed revenues
    of $176.8 million, $152.0 million and $160.6 million to the Company in the
    fiscal years 1997, 1996 and 1995, respectively. In connection with the Six
    Flags Transactions, SFEC is transfering its interests in the Co-Venture
    Parks to Premier. The pro forma statement of operations data for the year
    ended December 28, 1997 give effect to the transfer of such interests as if
    it occurred on December 30, 1996.
 
(2) Income from operations is revenue less operating, general and administrative
    expenses, costs of products sold and depreciation and amortization.
 
(3) EBITDA is defined as earnings before interest expense, net, income tax
    expense (benefit), depreciation and amortization and minority interest. The
    Company has included information concerning EBITDA because it is used by
    certain investors as a measure of the Company's ability to service and/or
    incur debt. EBITDA is not required by GAAP and should not be considered in
    isolation or as an alternative to net income, net cash provided by
    operating, investing and financing activities or other financial data
    prepared in accordance with GAAP or as an indicator of the Company's
    operating performance. This information should be read in conjunction with
    the Statements of Cash Flows contained in the financial statements included
    elsewhere herein.
 
(4) During each of the years ended December 28, 1997, December 29, 1996 and
    December 31, 1995, the Company's net cash used in investing activities was
    approximately $149.7 million, $81.2 million and $93.9 million, respectively.
    During these periods, net cash provided (used) in financing activities was
    approximately $10.6 million, $(52.2) million and $10.6 million,
    respectively.
 
 (5) Does not include amount expended ($62.7 million) by the Company to purchase
     interests in the limited partners of the Co-Venture Partnerships.
 
(6) For the purpose of determining the ratio of earnings to fixed charges and
    the ratio of earnings to combined fixed charges and preferred stock
    dividends, earnings consist of income (loss) before income taxes and fixed
    charges. Fixed charges consist of interest expense net of interest income,
    amortization of deferred financing costs and discount or premium relating to
    indebtedness and the portion (approximately one-third) of rental expense
    that management believes represents the interest component of rent expense.
    Preferred stock dividend requirements have been increased to an amount
    representing the before tax earnings which would have been required to cover
    such dividend requirements. On a pro forma basis, for the year ended
    December 28, 1997, the Company's earnings were insufficient to cover fixed
    charges and combined fixed charges and preferred stock dividends by $
    and $     , respectively.
 
(7) The pro forma balance sheet data give effect to the Six Flags Acquisition,
    the Offerings, the related financings, and the transfer of the Company's
    interests in the Co-Venture Parks to Premier as if they had occurred on
    December 28, 1997.

<PAGE>
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
    The Company's revenues are derived principally from the sale of tickets for
entrance to its parks, parking and corporate sponsorships (approximately 60.3%,
59.6% and 58.3% in the years ended December 28, 1997, December 29, 1996 and
December 31, 1995, respectively) and the sale of food, merchandise, gasoline,
games and attractions inside its parks and other income (approximately 39.7%,
40.4% and 41.7% in the years ended December 28, 1997, December 29, 1996 and
December 31, 1995, respectively). The Company's principal costs of operations
include salaries and wages, fringe benefits, advertising, outside services,
maintenance, utilities and insurance. The Company's expenses are relatively
fixed. Costs for full-time employees, maintenance, utilities, advertising and
insurance do not vary significantly with attendance, thereby providing the
Company with a significant degree of operating leverage as attendance increases
and fixed costs per visitor decrease.
 
RESULTS OF OPERATIONS
 
YEARS ENDED DECEMBER 28, 1997 AND DECEMBER 29, 1996
 
    REVENUES.  Revenues aggregated $708.7 million in 1997, compared to $680.9
million in 1996. The 4.1% increase in revenues is attributable to higher
spending per guest partially offset by decreased attendance. The average ticket
spending per guest increased 8.1% as a result of selected price increases and
reductions in ticket discounts. At large in-park spending per guest increased
4.4% primarily from gains in food service, stemming from improved processes,
quality and service and increases in games, attractions and parking spending.
Attendance declined by 2.5% primarily due to the postponement of the linear
induction motor ("LIM") coasters at three of the Company's parks, poor
early-season weather and increased price competition in the San Antonio market.
 
    OPERATING, GENERAL AND ADMINISTRATIVE.  Operating, general and
administrative expenses were $443.4 million in 1997, compared to $419.8 million
for 1996. As a percentage of revenues, these expenses constituted 62.6% for 1997
and 61.6 % for 1996. The increase over 1996 expenses relates primarily to
increased distributions to the limited partners of the Georgia park along with
higher compensation and maintenance expenses, which were partially offset by
reduced advertising costs and the reversal of expense accruals of approximately
$7.3 million during 1997 that are no longer deemed necessary. Limited partner
distributions increased as a result of the Georgia Agreements (as defined). The
higher compensation costs result from higher average seasonal wage rates,
additional operating hours in 1997, and a return to full staffing at the Georgia
park after reduced requirements in 1996. Higher maintenance costs were incurred
to repair major rides and facilities to enhance park operations. Advertising
costs were down due to lower spending by the Georgia park, which incurred much
higher advertising expense levels in 1996 as a result of the Olympics.
Additionally, the postponed opening of the LIM coasters resulted in lower
advertising costs at three of the Company's parks.
 
    As a result of the Texas Agreements (as defined), the distributions to the
limited partners of the Texas Park will increase by approximately $20 million in
1998, compared to 1997, assuming that the Company does not acquire any LP Units
pursuant to the SFOT tender offer.
 
    COSTS OF PRODUCTS SOLD.  Costs of products sold were $101.2 million for 1997
compared to $106.0 million for 1996. The $4.7 million or 4.5% decrease from 1996
results primarily from and improvement in the costs of products sold as a
percentage of product revenue. This percentage improvement resulted from
centralized procurement of key food items and a shift in sales to higher margin
food products sold.
 
                                       25
<PAGE>
    DEPRECIATION, AMORTIZATION AND INTEREST EXPENSE.  Depreciation and
amortization expense was $84.5 million for 1997 as compared to $87.4 million in
1996. The decrease resulted from lower amortization of the investment in the
Co-Venture Parks related to the Georgia Park and the Georgia Agreements.
Interest expense, net, increased $7.9 million in 1997, as compared to 1996,
primarily due to the increased at large borrowings in 1997 and higher interest
expense incurred at the Co-Venture Parks, partially offset by a decrease in at
large borrowing rates.
 
    INCOME TAXES.  The relationship between income (loss) before taxes and
income tax expense is principally affected by the amortization of the excess of
costs over net assets acquired, which is non-deductible for income tax purposes.
The income tax expense recorded for 1996 principally represents a valuation
allowance on the Company's deferred tax assets.
 
    At May 31, 1997, the Company had carryforwards of approximately $123.0
million of net operating losses ("NOLs") for Federal income tax purposes. The
NOLs are subject to review and potential disallowance by the Internal Revenue
Service upon audit of the Federal income tax returns of the Company and its
subsidiaries. In addition, the use of such NOLs is subject to limitations on the
amount of taxable income that can be offset with such NOLs. Some of such NOLs
also are subject to a limitation as to which of the subsidiaries' income such
NOLs are permitted to offset. Accordingly, no assurance can be given as to the
timing or amount of the availability of such NOLs to the Company and its
subsidiaries.
 
YEARS ENDED DECEMBER 29, 1996 AND DECEMBER 31, 1995
 
    REVENUES.  Revenues aggregated $680.9 million in 1996, a 8.2% increase over
1995 revenue of $629.5 million. This increase is primarily attributable to the
consolidation of Fiesta Park's operations in 1996 which accounted for
approximately $52.7 million of the total increase in revenues. The resulting
decrease in comparable revenues (exclusive of Fiesta Park's revenues) was due to
lower attendance, offset in part by higher average spending per guest.
Comparable in-park attendance declined by approximately 5.3%, while average
ticket spending per guest increased approximately 6.8% and average in-park
spending per guest increased approximately 3.9%. The decline in comparable
in-park attendance resulted primarily from unfavorable weather experienced by
several of the Company's theme parks, the adverse impact of the 1996 Summer
Olympics (which were held in Atlanta) on the Georgia park and the delayed
introduction of the SUPERMAN THE ESCAPE ride at Six Flags Magic Mountain (the
"Superman Ride"). The delayed introduction of the Superman Ride resulted from
propulsion issues with the new state-of-the-art technology incorporated into
this first 100-mile per hour thrill ride. The Superman Ride opened on March 15,
1997. The increases in average ticket spending per guest and average in-park
spending per guest were due to selected price increases, improvements to
retail/food outlets and product offerings, and new pay-per-ride Skycoasters at
Six Flag Over Texas, Six Flags Over Georgia, Six Flags AstroWorld, Six Flags St.
Louis and Six Flags Magic Mountain.
 
    OPERATING, GENERAL AND ADMINISTRATIVE.  Operating, general and
administrative expenses increased from approximately $388.1 million in 1995 to
approximately $419.8 million in 1996. These expenses (as a percentage of
revenue) constituted approximately 61.6% and 61.7% during 1996 and 1995,
respectively. The acquisition of Wet'n Wild in April 1995 (which was renamed Six
Flags Hurricane Harbor (Dallas)) and the consolidation of Fiesta Park's
operations accounted for approximately $39.3 million of the total increase in
operating, general and administrative expenses. The resulting $7.6 million
decrease in comparable expenses is primarily due to lower incentive compensation
in 1996, costs accrued in 1995 in connection with the reorganization of the
Company's headquarters and the absence of costs allocated from TWE (relating to
employees of TWE who served as senior management of the Company during 1995)
subsequent to June 1995.
 
    COSTS OF PRODUCTS SOLD.  Costs of products sold increased from $91.1 million
in 1995 to $106.0 million in 1996. A large portion of the increase
(approximately 59%) is a result of the consolidation of the Fiesta Park's
operations. Cost of products sold (as a percentage of in-park product revenue)
constituted
 
                                       26
<PAGE>
approximately 39.5% and 35.7%, during 1996 and 1995, respectively. Excluding
Fiesta Park, costs of products sold increased by 3.8% due to increased cost for
higher quality products and the mark-down/ write-off of slow moving inventory.
 
    DEPRECIATION, AMORTIZATION AND INTEREST EXPENSE.  Depreciation and
amortization expense aggregated approximately $87.4 million in 1996 and
approximately $83.4 million in 1995. Interest expense, net, increased from $63.3
million in 1995 to $76.5 million in 1996, due to an increase in the average
outstanding debt level combined with an increase in the average cost of debt,
both of which resulted from the full year effect of the issuance of the SFTP
Senior Subordinated Notes and borrowings under Six Flags' then existing credit
facility, in each case, in June 1995.
 
    INCOME TAXES.  The relationship between income (loss) before taxes and
income tax expense is principally affected by the amortization of the excess of
costs over net assets acquired, which is non-deductible for income tax purposes.
The tax expense recorded for 1996 principally represents a valuation allowance
on the Company's deferred tax assets.
 
LIQUIDITY, CAPITAL COMMITMENTS AND RESOURCES
 
    The operations of the Company are highly seasonal, with the majority of the
operating season occurring between Memorial Day and Labor Day. Most of the
Company's revenue is collected in the second and third quarters of each year
while most expenditures for capital improvements and major maintenance are
incurred when the parks are closed or operate only on weekends during the first
and fourth quarters of each year. See "Risk Factors -- Effects of Inclement
Weather; Seasonal Fluctuations of Operating Results." The Company employs a
substantial number of seasonal employees who are compensated on an hourly basis.
The Company is not subject to Federal or certain applicable state minimum wage
rates in respect of its seasonal employees. However, the 1996 increase of $.90
an hour over two years in the Federal minimum wage rate, and any increase in the
state minimum wage rates, may result over time in increased compensation expense
for the Company as it relates to these employees as a result of competitive
factors.
 
    During 1997, the Company generated $110.3 million in net cash provided by
operating activities. Net cash used in investing activities aggregated
approximately $149.7 million, $67.7 million of which represented amounts spent
for capital expenditures of the Company's wholly-owned theme parks and Fiesta
Texas and $62.7 million of which represented the amount expended to purchase
interests in the limited partners of the Co-Venture Partnerships. Net cash
provided by financing activities for 1997 aggregated $10.6 million reflecting
the net borrowings on revolving lines of credit, offset, in part, by the
repayment at that time of amounts outstanding under the revolving lines of
credit and proceeds from other interim loans, partially offset by payments on
term loans.
 
    At December 31, 1997, the Texas Co-Venture Partnership had a $15.0 million
line of credit available for anticipated working capital requirements and the
Georgia Co-Venture Partnership had a $19.0 million line of credit available for
working capital, capital expenditures and partner distributions.
 
    In addition to its obligations under its outstanding indebtedness and
preferred stock, Premier, along with the Company and SFTP, has guaranteed
certain obligations of the Co-Venture Parks to (i) make minimum annual
distributions of approximately $46.2 million (subject to cost of living
adjustments) to its partners in the Co-Venture Parks and (ii) make minimum
capital expenditures at each of the Co-Venture Parks during rolling five-year
periods, based generally on 6% of such park's revenues. Cash flow from
operations at the Co-Venture Parks will be used to satisfy these requirements
first, before any funds are required from Premier, the Company or SFTP. Premier
has also agreed to purchase a maximum number of 5% per year (accumulating to the
extent not purchased in any given year) of the total limited partnership units
of these partnerships (to the extent tendered by the unit holders) and the
Company and SFTP have guaranteed these obligations. The agreed price for these
purchases is based on a valuation for each respective Co-Venture Park equal to
the greater of (i) a value derived by multiplying its weighted-average
 
                                       27
<PAGE>
four year EBITDA by a specified multiple (8.0 in the case of the Georgia park
and 8.5 in the case of the Texas park) or (ii) $250.0 million in the case of the
Georgia park and $374.8 million in the case of the Texas park. Premier's
obligations with respect to Six Flags Over Georgia and Six Flags Over Texas will
continue until 2026 and 2027, respectively. As Premier purchases limited
partnership units, it will be entitled to the minimum distribution and other
distributions attributable to such units, unless it is then in default under the
Subordinate Indemnity Agreement. Premier estimates that its maximum unit
purchase obligation for 1998, when purchases are required only for the Georgia
park, will aggregate approximately $13 million (approximately $32 million for
1999, when purchases for both partnerships are required) and its minimum capital
expenditures for 1998 at these parks will total approximately $18 million.
 
    The Company accounted for Six Flags Over Georgia and Six Flags Over Texas as
co-ventures, i.e., the revenues and expenses (excluding partnership
depreciation) are included in the Company's consolidated statements of
operations and the net amounts distributed to the limited partners are deducted
as expenses. Except for the limited partnership units purchased pursuant to the
tender offer, the Company has no rights or title to the Co-Venture Park assets
or to the proceeds from any sale of the Co-Venture Park's assets. Accordingly,
the Company's consolidated balance sheets do not include any of the Co-Venture
Parks' assets. The investment in the Co-Venture Parks included in the
consolidated balance sheets represents (i) the Company's interest in the
estimated future cash flows from the operations of the Co-Venture Parks and is
amortized over the life of the partnership agreements, (ii) the value of Limited
Partnership units purchased pursuant to the SFOG tender offer, and (iii) capital
contributions made by the Company to the Co-Venture Parks. The Co-Venture Parks
contributed revenues of $176.8 million, $152.0 million and $160.6 million to the
Company in the fiscal years 1997, 1996 and 1995, respectively.
 
    In connection with the Six Flags Transaction, SFEC is transferring its
interests in the Co-Venture Parks to Premier. Accordingly, cash flows from these
parks will not be available to service the debt of SFEC (including the SFEC
Senior Notes) except to the extent any such funds are contributed to SFEC by
Premier.
 
    The SFEC Senior Notes will require annual interest payments of $
and, except in the event of a change of control of the Company or certain other
circumstances, will not require any principal payments prior to their maturity.
The net proceeds of the Offering, together with other funds, will be deposited
in escrow to repay in full at or prior to maturity the SFEC Zero Coupon Senior
Notes. The SFTP Senior Subordinated Notes (accreted value of $269.9 million at
December 31, 1997) require interest payments of approximately $34.9 million per
annum, payable semi-annually commencing December 15, 1998, and, except in
certain circumstances, no principal payments are due thereon until their
maturity date, June 15, 2005. Term loan borrowings under the Six Flags Credit
Facility will mature on November 30, 2004 (with principal payments of $1.0
million in each of 1998--2001, $25.0 million in 2002, $40.0 million in 2003 and
$303.0 million at maturity), Revolving credit borrowings under this facility
($100.0 million) mature on the fifth anniversary of the Six Flags Acquisition.
Borrowings under the Six Flags Credit Facility will be guaranteed by SFTP's
subsidiaries and will be secured by substantially all of the assets of SFTP and
its subsidiaries. See "Description of Other Company Indebtedness," and
"Description of Notes."
 
    By reason of the Six Flags Acquisition, SFTP will be required to offer to
purchase the SFTP Senior Subordinated Notes at a price equal to 101% of their
accreted amount (approximately $287.9 million at June 15, 1998). On February
      , 1998, the last reported sales price of these notes was equivalent to
   % of their accreted amount. SFTP does not expect to be required to purchase
any material amount of these Notes by reason of this offer. Although Premier has
entered into discussions with lenders to provide a standby arrangement to
finance the purchase of such Notes, there can be no assurance that such
discussions will be successful or that Premier will be able to obtain any other
financing in the event that it should become necessary.
 
    The Company's liquidity could be adversely affected by unfavorable weather,
accidents or the occurrence of an event or condition, including negative
publicity or significant local competitive events
 
                                       28
<PAGE>
(such as the 1996 Summer Olympics in the case of Six Flags Over Georgia) that
significantly reduces paid attendance and, therefore, revenue at any of its
theme parks.
 
    On a pro forma basis, as of December 28, 1997, the Company had total
outstanding indebtedness of approximately $   million, including: (i) $
million under the Six Flags Credit Facility, (ii) $269.9 million in accreted
value at that date of SFTP Senior Subordinated Notes ($285.0 million principal
amount at maturity in 2005), and (iii) $170.0 million under the SFEC Senior
Notes. Indebtedness at that date also included $160.1 million accreted value of
SFEC Zero Coupon Senior Notes, which will be repaid with the proceeds of the
SFEC Senior Notes together with certain additional funds. On a pro forma basis,
for the year ended December 28, 1997, the Company's earnings would have been
insufficient to cover its combined fixed charges by approximately $   million.
In addition the indentures relating to the SFEC Senior Notes and the SFTP Senior
Subordinated Notes and the Six Flags Credit Facility permit the Company to incur
additional indebtedness under certain circumstances. See "Description of Other
Company Indebtedness" and "Description of Notes--Certain Covenants."
 
    In addition to the Company's indebtedness, following the Six Flags
Transactions, on a pro forma basis, as of December 31, 1997, Premier had
outstanding indebtedness of approximately $    million, including: (i)
$   million of Six Flags indebtedness, as described above; (ii) $250.0 million
in accreted value at that date of the Premier Discount Notes ($    million
principal amount at maturity in 2008); (iii) $280.0 million in aggregate
principal amount of Premier Senior Notes; (iv) $125.0 million in aggregate
principal amount of 1997 Premier Notes; (v) $90.0 million in aggregate principal
amount of 1995 Premier Notes; and (vi) $         million in outstanding
borrowings under the Premier Credit Facility. On a pro forma basis, as of
December 31, 1997, Premier would have had stockholders' equity of approximately
$         million. In addition, the annual dividends (which are payable in cash,
in the case of the Seller Preferred Stock, or in cash, or by issuance of shares
of Common Stock, at the option of the Company, in the case of the Mandatorily
Convertible Preferred Stock) on the Convertible Preferred Stock aggregate
$         , and the Seller Preferred Stock is mandatorily redeemable in 2010 (if
not earlier redeemed or converted). On a pro forma basis, for the year ended
December 31, 1997, Premier's earnings would have been insufficient to cover its
combined fixed charges and preferred stock dividends by approximately $
million. In addition, the Indentures permit Premier to incur additional
indebtedness under certain circumstances. See "Risk Factors--Risks Associated
with Substantial Indebtedness," "Capitalization," "Description of Other Company
Indebtedness," "Description of Notes--Certain Covenants" and "Description of
Premier Indebtedness."
 
    Premier believes that cash flow from operations and available cash and
available borrowings under the Six Flags Credit Facility will be adequate to
meet the Company's future liquidity needs, including anticipated requirements
for working capital, capital expenditures and scheduled debt, for at least the
next several years. Premier believes that cash flow from operations and
available cash, available borrowings under the Credit Facilities and the net
proceeds of the Offerings (to the extent not used in connection with the Six
Flags Acquisition) will be adequate to meet Premier's future liquidity needs,
including anticipated requirements for working capital, capital expenditures,
scheduled debt and preferred stock payments and its obligations under
arrangements relating to the Co-Venture Parks, for at least the next several
years. See "Risk Factors--Risks Associated with Substantial Indebtedness."
 
NEWLY ISSUED ACCOUNTING STANDARDS
 
    In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income." SFAS
No. 130 is effective for fiscal years beginning after December 15, 1997. SFAS
No. 130 establishes standards for reporting and display of "comprehensive
income" and its components in a set of financial statements. It requires that
all items that are required to be recognized under accounting standards as
components of comprehensive income be reported in a financial statement that is
displayed with the same prominence as other financial statements.
 
                                       29
<PAGE>
The Company currently does not have any components of comprehensive income that
are not included in net income.
 
    Also in June 1997, Statement of Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related Information," was
issued. SFAS No. 131 is effective for periods beginning after December 15, 1997.
SFAS No. 131 requires that a public entity report financial and descriptive
information about its reportable segments. Operating segments are components of
an enterprise about which separate financial information is available that is
evaluated regularly by the chief operating decision maker in deciding how to
allocate resources and in assessing performance. The Company will adopt SFAS No.
131 in 1998. However, such adoption is not expected to impact the Company's
financial disclosures because the Company's current operations are limited to
one reportable operating segment under SFAS No. 131's definitions.
 
    In January 1997, the Commission issued Release No. 33-7386, which requires
enhanced descriptions of accounting policies for derivative financial
instruments and derivative commodity instruments in the footnotes to financial
statements. The release also requires certain quantitative and qualitative
disclosure outside financial statements about market risks inherent in market
risk sensitive instruments and other financial instruments. The requirements
regarding accounting policy descriptions were effective for any fiscal period
ending after June 15, 1997. However, because derivative financial and commodity
instruments have not materially affected the Company's consolidated financial
position, cash flows or results of operations, this part of the release does not
affect the Company's 1997 financial statement disclosures.
 
IMPACT OF YEAR 2000 ISSUE
 
    An issue exists for all companies that rely on computers as the year 2000
approaches. The "Year 2000" problem is the result of past practices in the
computer industry of using two digits rather than four to identify the
applicable year. This practice will result in incorrect results when computers
perform arithmetic operations, comparisons or data field sorting involving years
later than 1999. The Company has completed plans to ensure year 2000 compliance
and started conversions of applications beginning in 1996. These modifications
and replacements are expected to be completed by January 1999. Costs in
connection with any such modifications are not expected to be material. See
"Risk Factors -- Impact of Year 2000 Issue."

GENERAL
 
    Six Flags is the largest regional theme park company, and the second largest
theme park operator, in the world, based on 1997 attendance. Six Flags operates
eight regional theme parks, as well as three separately gated water parks and a
wildlife safari park (each of which is located near one of the theme parks). The
Six Flags Parks are located in six of the ten largest metropolitan areas in the
country: New York, Philadelphia, Los Angeles, Chicago, Atlanta and Dallas. The
Company estimates that    % of the U.S. population lives within a 100-mile
radius of the Six Flags Parks. During 1997, the Six Flags Parks drew, in the
aggregate, approximately    % of their patrons from within a 100-mile radius.
During that year, Six Flags' attendance, revenue and EBITDA totaled
approximately 22.3 million, $708.7 million and $164.1 million, respectively.
 
    The following table sets forth certain information for the Six Flag's Parks:

(1) Includes acreage currently dedicated to park usage. Additional acreage
    suitable for development exists at many of the facilities.
 
(2) Attendance and acreage information for Six Flags Great Adventure also
    includes data for the adjacent Six Flags Wild Safari Animal Park.
 
    Six Flags, including its predecessors, has operated regional theme parks
under the Six Flags name for over thirty years. As a result, Six Flags has
established a nationally-recognized brand name. Since 1991, Six Flags has used
certain Warner Bros. and DC Comics characters to market its parks and to provide
an enhanced family entertainment experience. These characters include BUGS
BUNNY, DAFFY DUCK, TWEETY BIRD, YOSEMITE SAM, BATMAN, SUPERMAN and others. The
Company utilizes these characters in marketing its parks, in theming revenue
outlets and in selling character merchandise within the parks. The Company
believes that its extensive use of the Warner Bros. and DC Comics characters
promotes attendance, supports higher ticket prices, increases lengths-of-stay
and enhances in-park spending.
 
    The Six Flags Parks are individually themed and provide a complete
family-oriented entertainment experience. The Six Flags Parks generally offer a
broad selection of state-of-the-art and traditional thrill rides, water
attractions, themed areas, concerts and shows, restaurants, game venues and
merchandise outlets. In the aggregate, the Six Flags Parks offer more than 300
rides, including [57] roller coasters, making Six Flags one of the leading
providers of "thrill rides" in the industry.
 
    Premier believes that the Company's parks benefit from limited direct
competition. The combination of limited supply of real estate appropriate for
theme park development, high initial capital investment, long development
lead-time and zoning restrictions provides each of the parks with a significant
degree of protection from competitive new theme park openings. Based on its
knowledge of the development of other theme parks in the United States,
Premier's management estimates that it would cost at least $200
 
                                       31
<PAGE>
million and would take a minimum of two years to construct a new regional theme
park comparable to the Company's largest parks.
 
    According to AMUSEMENT BUSINESS, total North American amusement/theme park
attendance in 1997 was approximately 270 million, compared to       million in
1994 (the first year in which such information is available from that
publication), representing a compound annual growth rate of    %. Total
attendance for the 40 largest parks in North America was 154.7 million in 1997,
compared to       million in 1992, representing a compound annual growth rate of
   %. Premier believes that this growth reflects two trends: (i) demographic
growth in the 5-24 year old age group, which is expected to continue through
2010; and (ii) an increasing emphasis on family-oriented leisure and recreation
activities.
 
OPERATING STRATEGY
 
    Premier believes there are substantial opportunities for continued internal
growth at the Six Flags Parks. Upon consummation of the Six Flags Acquisition,
Premier's management intends to apply its operating strategy to pursue revenue
growth and margin expansion at Six Flags. Premier's operating strategy seeks to
increase revenues by increasing per capita spending, while also reducing
corporate overhead and improving cost controls at the Six Flags Parks. This
approach is designed to exploit the operating leverage inherent in the theme
park business. Once parks achieve certain critical attendance levels, operating
cash flow margins increase because revenue growth through incremental attendance
gains and increased in-park spending is not offset by a comparable increase in
operating expenses, since a large portion of such expenses is relatively fixed
during any given year. The primary elements of this operating strategy
applicable to the Six Flags Park include:
 
    --ADDING RIDES AND ATTRACTIONS AND IMPROVING OVERALL PARK QUALITY.  Premier
regularly makes investments in the development and implementation of new rides
and attractions at its parks. Premier believes that the introduction of
marketable rides is an important factor in promoting each of the parks in order
to increase market penetration and encourage longer visits, which lead to
increased attendance and sales of food and merchandise. Once a park reaches an
appropriate level of attractions for its market size, Premier will add new
marketable attractions at that park only every three to four years.
 
    --ENHANCING MARKETING AND SPONSORSHIP PROGRAMS.  The Six Flags Parks have
benefitted from professional, creative marketing programs which emphasize the
marketable rides and attractions, breadth of available entertainment and value
provided by each park. The Company's marketing programs emphasize the Six Flags
brand name, as well as the animated characters licensed from Warner Bros. The
Company has also successfully attracted well known sponsorship and promotional
partners, such as McDonald's, Coca-Cola, First USA Bank and Best Western.
 
    --INCREASING AND ENHANCING RESTAURANTS AND MERCHANDISE AND OTHER REVENUE
OUTLETS TO INCREASE LENGTH OF STAY AND IN-PARK SPENDING.  Premier also seeks to
increase in-park spending by adding well-themed restaurants, remodeling and
updating existing restaurants and adding new merchandise outlets. Additionally,
the Company has taken steps to decrease the waiting time for its most popular
restaurants and merchandise outlets.
 
    --ADDING SPECIAL EVENTS.  The Company has also developed a variety of
off-season special events designed to increase attendance and revenue prior to
Memorial Day and after Labor Day. Examples include Fright
Fest-Registered Trademark-, a Halloween event in which parks are transformed
with supernatural theming, scary rides and haunting shows, and Holiday in the
Park-Registered Trademark-, a winter holiday event, in which several parks are
transformed with winter and holiday theming.
 
    The Six Flags Parks generally enjoy significant market penetration. Thus,
although Premier plans to make targeted capital expenditures at these parks to
increase their attendance and per capita spending levels, it expects to increase
significantly the EBITDA of these parks primarily through reduction in operating
expenses. First and most importantly, Premier believes that it can substantially
reduce Six Flags'
 
                                       32
<PAGE>
corporate overhead and other corporate-level expenses. Second, Premier expects
to achieve significant reduction in park-level operating expenses. Third, by
virtue of economies of scale, Premier believes that operating efficiencies in
areas such as marketing, insurance, promotion, purchasing and other expenses can
be realized. Finally, Premier believes that its increased size following the Six
Flags Acquisition will enable it to achieve savings in capital expenditures,
including its ability to rotate rides among its parks.
 
EXPANSION STRATEGY
 
    Premier may expand in the future certain of the Six Flags Parks by adding
complementary attractions, such as campgrounds, lodging facilities, new water
parks and concert venues. For example, Six Flags owns over 1,500 undeveloped
acres adjacent to Six Flags Great Adventure (located between New York City and
Philadelphia) suitable for such purposes. Additional acreage suitable for
development exists at several other Six Flags Parks.
 
ACQUISITION STRATEGY
 
    The U.S. regional theme park industry is highly fragmented with over 150
parks owned by over 100 operators. Premier believes that there are numerous
acquisition opportunities, both in the U.S. and abroad, that can expand its
business. Since 1989, Premier has pursued a strategy of acquiring and improving
regional theme parks. Premier's primary target for acquisitions continues to be
regional parks with attendance between 300,000 and 1.5 million annually, but
will also consider acquisitions of larger parks or park chains. Although it
anticipates making new acquisitions primarily through Premier Operations,
Premier may also make acquisitions of additional parks through Six Flags.
 
THE THEME PARK INDUSTRY
 
    HISTORY
 
    Although there is a long history of traditional amusement parks, primarily
family-owned and consisting of thrill rides and midways, the opening of
Disneyland in 1955 introduced the first modern theme park. Several features of
modern theme parks distinguish them from the traditional amusement park whose
carnival atmosphere and thrill rides offer less to families and adults. Theme
parks are designed around one central or several different themes which are
consistently applied to all areas, including the rides, attractions,
entertainment, food, restaurants and landscape. Modern parks also typically
present a variety of free entertainment not found at old-style amusement parks.
Theme parks also offer the visitor numerous and diverse dining establishments in
order to expand length of stay and position the parks as an all-day
entertainment center. Generally, theme parks also plan nighttime entertainment
(such as fireworks) and special events, and keep certain rides open into the
night to further extend the hours of operation. As a result of these
differences, theme parks draw attendance from a wider geographic area and
attract a larger number of people from within a given market. Theme parks also
attract more families and group outings, and the average length of stay and per
capita outlay is greater.
 
    The following table identifies the nine largest operators of theme park
chains worldwide ranked by total attendance, showing the number and type of such
parks operated by each and the aggregate attendance in 1997.

    DESTINATION PARKS VERSUS REGIONAL PARKS
 
    Destination parks are those designed primarily to attract visitors willing
generally to travel long distances and incur significant expense to visit the
parks' attractions as part of an extended stay. To accommodate vacationers, many
destination parks also include on-site lodging. Walt Disney World and Universal
Studios are well-known examples of this type of park. Management believes that
destination parks are typically more affected by the national economy than are
regional parks. With the exception of Six Flags Magic Mountain, located in the
same market as Disneyland and Universal Studios Hollywood, the Company does not
believe that its parks compete directly with destination parks.
 
    Regional theme parks, such as those historically operated by the Company,
are designed to attract visitors for a full day or a significant number of
hours. Management views regional theme parks as those that draw the majority of
their patrons from within a 50-mile radius of the park and the great majority of
their visitors from within a 100-mile radius of the park. Visiting a regional
theme park may be significantly less expensive than visiting a destination park
because of lower transportation expenses, lower ticket prices and the lack of
extended lodging expenses. The U.S. regional theme park industry is highly
fragmented with over 150 parks owned by over 100 operators.
 
    ATTRACTIONS
 
    Regional theme parks attract patrons of all ages. Families and young people
are attracted by the variety of major rides and attractions, children's rides
and various entertainment areas including thematic shows and concerts. Most park
admission policies are "pay-one-price," which entitles a guest to virtually
unlimited free access to all rides, shows and attractions.
 
    Depending on the size of the property, regional theme parks typically have
between 30 and 40 attractions. These rides include roller coasters and water
rides, as well as other attractions such as bumper cars, aerial rides and
children's rides. A park may also have distinct entertainment and show areas
with specific themes such as a wild west or pirate stunt show. Games, food and
merchandise stands often reflect the theme of the particular area in which they
are located. This enhances the promotional effect of the thematic area. By
offering a variety of rides and themed areas, a park is able to target a wider
age spectrum from the surrounding population.
 
    In addition to thrill rides, many parks offer indoor attractions and outdoor
concerts, ranging from musical skits and bands to full-scale evening concerts by
prominent entertainers. Selected concerts may require an add-on to the
admissions price, but often are part of the regular ticket price, providing
added value to visitors.
 
    Food service offered ranges from full-service restaurants to fast food.
Young people may only be interested in a quick meal between rides while the
family may choose to relax for a picnic. Refreshment stands serve snack foods,
such as hot dogs, cotton candy and soda. In addition, game booths and
merchandise souvenir stands are dispersed throughout a park.
 
HISTORY
 
    Six Flags, including its predecessors, has been in the theme park business
since 1961. Six Flags was incorporated in Delaware in 1981 under the name "Six
Flags Corporation" in connection with the acquisition by Bally Manufacturing
Corporation ("Bally") of Six Flags Corporation from Penn Central Corporation. In
1987, Bally sold its interest in Six Flags Corporation to an investor group
organized and
 
                                       34
<PAGE>
led by Wesray Capital Corporation (the "Wesray Group"). In 1990, Time Warner
Enterprises Inc. ("Enterprises"), a subsidiary of Time Warner, acquired a 20%
interest in Six Flags Corporation. In 1991, Enterprises, together with
Blackstone Capital Partners L.P. ("Blackstone") and a limited partnership
organized by Wertheim Schroder & Co. Incorporated ("WSW"), organized SFEC, which
acquired Six Flags Corporation from Wesray Group. As a result of such
acquisition, Enterprises owned 50% of SFEC, and Blackstone and WSW owned the
remaining 50%. In June 1992, Time Warner caused all of Enterprises' interest in
SFEC and Six Flags Corporation to be contributed to TWE. In December 1992,
Blackstone substantially reduced and WSW substantially increased their
respective interests in SFEC. Also in 1992, Six Flags Corporation's name was
changed to its current name "Six Flags Theme Parks Inc." In 1993, SFEC
repurchased the equity interest held by Blackstone and WSW and as a result
thereof, SFEC became a wholly-owned subsidiary of TWE. On June 23, 1995, TWE
sold 51% of its interest in SFEC to the Investor Group led by Boston Ventures.
On February 9, 1998, pursuant to the Six Flags Agreement, Premier agreed to
acquire, by merger, all of the capital stock of SFEC from its current
stockholders.
 
DESCRIPTION OF PARKS
 
    Six Flags operates 12 "Six Flags" branded theme parks in eight locations in
the United States, consisting of eight major regional theme parks, as well as
three separately gated water parks and one wildlife safari park (each located
near one of the theme parks). The Six Flags Parks include:
 
    SIX FLAGS ASTRO-WORLD AND SIX FLAGS WATERWORLD
 
    Six Flags Astro-World, the 28th largest theme park in the United States with
1997 attendance of 2.0 million, and the separately gated adjacent Six Flags
WaterWorld, with 1997 attendance of 283,000, are located in Houston, Texas on
the grounds of an entertainment and sports complex that includes the Houston
Astrodome. The Houston, Texas market provides the parks with a permanent
resident population of    million people within 50 miles and       million
people within 100 miles. The Houston market is the number 11 DMA in the United
States. Based upon in-park surveys, approximately   % of the visitors to the
parks in 1997 resided within a 50-mile radius of the park, and   % resided
within a 100-mile radius.
 
    The Company owns a site of approximately 90 acres used for the theme park,
and approximately 14 acres used for the water park. Six Flags Astro-World
indirectly competes with Sea World of Texas and the Company's Six Flags Fiesta
Texas, both located in San Antonio, Texas, approximately 200 miles from the
park. Six Flags WaterWorld competes with Splashtown and Water Works, two nearby
water parks.
 
    SIX FLAGS FIESTA TEXAS
 
    Six Flags Fiesta Texas, the 33rd largest theme park in the United States
with 1997 attendance of 1.6 million, is located in San Antonio, Texas. The San
Antonio, Texas market provides the park with a permanent resident population of
   million people within 50 miles and    million people within 100 miles. The
San Antonio market is the number 38 DMA in the United States. Based upon in-park
surveys, approximately   % of the visitors to the parks in 1997 resided within a
50-mile radius of the park, and    % resided within a 100-mile radius.
 
    Six Flags Fiesta Texas' principal competitor is Sea World of Texas located
in San Antonio. In addition, the park competes to a lesser degree with Six Flags
Astro-World, the Company's park located in Houston, Texas, approximately 200
miles from the park.
 
    PARTNERSHIP STRUCTURE.  In March 1996, Six Flags completed arrangements
under which it took over management of the then named Fiesta Texas park ("Fiesta
Park"). Fiesta Park is located on 200 acres and is owned by La Cantera
Development Company ("La Cantera"), an affiliate of United Service Automobile
Associates and is leased to a then formed new limited partnership (the "Fiesta
Partnership"). Pursuant to the terms of the lease (the "Fiesta Lease"), the
Fiesta Partnership pays La Cantera a nominal annual
 
                                       35
<PAGE>
rental and is required to make certain capital improvements to and cover all
operating expenses of the park.
 
    The Fiesta Partnership is a limited partnership formed by Six Flags San
Antonio, L.P., a Delaware limited partnership between two wholly-owned
subsidiaries of the Company (the "Six Flags GP"), as general partner, San
Antonio Park GP, LLC, a Delaware limited liability company which is managed by
managers elected by TWE, on the one hand, and an investor group, on the other
hand and in which SFEC holds a non-voting 99% equity interest (the "LLC GP"), as
general partner, and Fiesta Texas Theme Park, Ltd., a Texas limited partnership
wholly-owned by La Cantera (the "La Cantera LP"), as limited partner. The Fiesta
Partnership is controlled by the general partners and is owned 59% by the Six
Flags GP, 1% by the LLC GP and 40% by the La Cantera LP, which interests reflect
the partners' respective original contributions to the Fiesta Partnership.
 
    The Fiesta Lease has an initial term which extends through the end of fiscal
year 2005, but under certain circumstances may be extended until the end of
fiscal year 2015. The extended Fiesta Lease can be terminated at the end of
fiscal year 2010 at the option of either the Fiesta Partnership or the lessor,
La Cantera LP. The Fiesta Partnership will also have the right to terminate the
Fiesta Lease effective at the end of fiscal year 2001 based on a specified
cumulative operating loss for the 1998 through 2001 fiscal years. As long as the
Fiesta Lease continues in effect, the Fiesta Partnership has the option to
purchase the tangible and intangible assets of Fiesta Park, as well as the La
Cantera LP's interest in the Fiesta Partnership, during the initial term of the
Fiesta Lease, at the end of fiscal year 2010 should the lessor terminate the
Fiesta Lease and at the end of fiscal year 2015.
 
    In connection with Six Flags' management of Fiesta Park, the Six Flags GP
entered into a management agreement with the Fiesta Partnership (the "Management
Agreement") under which it will manage and operate Fiesta Park on the Fiesta
Partnership's behalf. Under the terms of the Management Agreement, the Fiesta
Partnership will pay the Six Flags GP an annual management fee and intellectual
property fee. For the 1996 and 1997 fiscal years, the annual management fee
payable to the Six Flags GP was 6% of the Fiesta Partnership's Gross Revenues
(as defined in the Management Agreement) for such year. Commencing with the 1998
fiscal year, the management fee is 25% of EBITDA (as defined in the Management
Agreement). The intellectual property fee payable to the Six Flags GP throughout
the term of the Management Agreement will be based on the Fiesta Partnership's
Gross Revenues.
 
    SIX FLAGS GREAT ADVENTURE AND SIX FLAGS WILD SAFARI ANIMAL PARK
 
    Six Flags Great Adventure, the 10th largest theme park in the United States,
and the separately gated adjacent Six Flags Wild Safari Animal Park, the 23rd
largest theme park in the United States with 1997 combined attendance of 3.7
million, are located in Jackson, New Jersey, approximately 70 miles south of New
York City and 50 miles east of Philadelphia. The New York and Philadelphia
markets provide the parks with a permanent resident population of     million
people within 50 miles and     million people within 100 miles. The New York and
Philadelphia markets are the number 1 and number 4 DMAs in the United States,
respectively. Based upon in-park surveys, approximately     % of the visitors to
the parks in 1997 resided within a 50-mile radius of the park, and     % resided
within a 100-mile radius.
 
    The Company owns a site of approximately 1,862 acres, of which approximately
221 acres are currently used for the thrill-ride based theme park operations,
and 1,641 acres remain undeveloped. Additionally, the Company owns approximately
355 adjacent acres that are used for the wildlife safari park, home to 55
species of 1,200 exotic animals which can be seen over a four and a half mile
drive. Six Flags Great Adventure's principal competitors are Hershey Park,
located in Hershey, Pennsylvania, approximately 150 miles from the park; and
Dorney Park, located in Allentown, Pennsylvania, approximately 75 miles from the
park.

    SIX FLAGS GREAT AMERICA
 
    Six Flags Great America, the 16th largest theme park in the United States
with 1997 attendance of 3.0 million, is located in Gurnee, Illinois, between
Chicago, Illinois and Milwaukee, Wisconsin. The Chicago and Milwaukee markets
provide the park with a permanent resident population of     million people
within 50 miles and     million people within 100 miles. The Chicago and
Milwaukee markets are the number 3 and number 31 DMAs in the United States,
respectively. Based upon in-park surveys, approximately     % of the visitors to
the park in 1997 resided within a 50-mile radius of the park, and     % resided
within a 100-mile radius.
 
    The Company owns a site of approximately 86 acres used for the theme park
operations. Six Flags Great America currently has no direct theme park
competitors in the region, but does compete with Paramount's Kings Island,
located near Cincinnati, Ohio, approximately 350 miles from the park; Cedar
Point, located in Sandusky, Ohio, approximately 340 miles from the park; and Six
Flags St. Louis, the Company's park located near St. Louis, Missouri,
approximately 320 miles from the park.
 
    SIX FLAGS MAGIC MOUNTAIN AND SIX FLAGS HURRICANE HARBOR
 
    Six Flags Magic Mountain, the 12th largest theme park in the United States
with 1997 attendance of 3.3 million, and the separately gated adjacent Six Flags
Hurricane Harbor, the 11th largest water park in the United States with 1997
attendance of 351,000, are located in Valencia, California, in the northwest
section of Los Angeles County. The Los Angeles, California market provides the
parks with a permanent resident population of       million people within 50
miles and       million people within 100 miles. The Los Angeles market is the
number 2 DMA in the United States. Based upon in-park surveys, approximately
   % of the visitors to the parks in 1997 resided within a 50-mile radius of the
parks, and    % resided within a 100-mile radius.
 
    The Company owns a site of approximately 110 acres used for the theme park,
and approximately 11 acres used for the pirate-themed water park. Six Flags
Magic Mountain's principal competitors include Disneyland in Anaheim,
California, located approximately 60 miles from the park, Universal Studios
Hollywood in Universal City, California, located approximately 20 miles from the
park, Knott's Berry Farm in Buena Park, California, located approximately 50
miles from the park, and Sea World of California in San Diego, California,
located approximately 150 miles from the park. Six Flags Hurricane Harbor has no
direct competitors in the area.
 
    SIX FLAGS OVER GEORGIA
 
    Six Flags Over Georgia, the 20th largest theme park in the United States
with 1997 attendance of 2.8 million, is located in Mableton, Georgia,
approximately 10 miles outside of Atlanta, Georgia. The Atlanta, Georgia market
provides the park with a permanent resident population of     million people
within 50 miles and     million people within 100 miles. The Atlanta market is
the number 10 DMA in the United States. Based upon in-park surveys,
approximately     % of the visitors to the park in 1997 resided within a 50-mile
radius of the park, and     % resided within a 100-mile radius.
 
    Six Flags Over Georgia's primary competitors include Paramount's Carowinds
in Charlotte, North Carolina, located approximately 250 miles from the park, and
Dollywood in Pigeon Forge, Tennessee, located approximately 200 miles from the
park. The Georgia Limited Partnership (as defined below) owns the site of
approximately 283 acres, including approximately 87 acres of undeveloped land,
all of which is leased to Six Flags Over Georgia II (the "Georgia Co-Venture
Partnership").
 
    PARTNERSHIP STRUCTURE.  On March 18, 1997, Six Flags completed arrangements
pursuant to which Six Flags will manage the Georgia park through 2026. Under the
agreements governing the new arrangements (the "Georgia Agreements"), the
Georgia park is to be owned by the Georgia Co-Venture Partnership of which a Six
Flags subsidiary is the managing general partner. In the second quarter of 1997,
two
 
                                       37
<PAGE>
subsidiaries of Six Flags made a tender offer for partnership interests ("LP
Units") in the 99% limited partner of the Georgia Co-Venture Partnership (the
"Georgia Limited Partnership"), that values the Georgia park at the greater of
$250 million or eight times 1997 EBITDA of the Georgia park (the "Tender Offer
Price"). Six Flags purchased approximately 25% of the LP Units in the 1997
tender offer at an aggregate price of $60.1 million. In connection with the Six
Flags Transactions, SFEC will transfer its interests in Six Flags Over Georgia
to Premier.
 
    The key elements of the new arrangements are as follows: (i) the limited
partner (which is not affiliated with Six Flags) received minimum annual
distributions of $18.5 million in 1997, which will increase each year thereafter
in proportion to increases in the cost of living; (ii) thereafter, Six Flags
will be entitled to receive from available cash (after provision for reasonable
reserves and after capital expenditures per annum of approximately 6% of prior
year's revenues) a management fee equal to 3% of the prior year's gross
revenues, and, thereafter, any additional available cash will be distributed 95%
to Six Flags and 5% to the limited partner; (iii) commencing in 1998, and on an
annual basis thereafter, Six Flags will offer to purchase additional LP Units at
a price based on a valuation for the park equal to the greater of $250.0 million
or a value derived by multiplying the weighted average four year EBITDA by 8.0;
(iv) in 2026, Six Flags will have the option to acquire all remaining interests
in the Georgia park at a price based on the Tender Offer Price, increased in
proportion to the increase in the cost of living between December 1996 and
December 2026, and (v) the Company is required to make minimum capital
expenditures at the Georgia park during rolling five-year periods, based
generally on 6% of such park's revenues. Cash flow from operations at the
Georgia park will be used to satisfy these requirements first, before any funds
are required from the Company. In connection with the Subordinate Indemnity
Agreement, the Company is transferring to Time Warner (who has guaranteed the
Six Flags obligations under these arrangements) record title to certain entities
that have purchased and will purchase LP Units, and the Company will receive an
assignment from Time Warner of all cash flow received on such LP Units and will
otherwise control such entities, except in the event of a default by the Company
of its obligations under these arrangements. After all such obligations have
been satisfied, Time Warner is required to transfer to the Company such stock
for a nominal consideration. In addition, the Company will issue preferred stock
of the managing partner of the Georgia Partnership to Time Warner which, in the
event of such a default, would permit Time Warner to obtain control of such
entity. See "Description of Six Flags Agreement."
 
    Six Flags has accounted for the Georgia park as a co-venture and included
the revenues and expenses of the Georgia Co-Venture Partnership (excluding
partnership depreciation and interest expense associated with limited
partnership debt) in Six Flags' consolidated financial statements and deducted
as expenses the net amounts distributed to the limited partners. Under the
previous partnership agreement for the Georgia Co-Venture partnership, net cash
flow (as defined in the partnership agreement) was distributed in the following
order: $2.1 million to the limited partner; then $2.1 million to the general
partner; then a management fee to the general partner equal to 3% of the
preceding year's gross revenues; and finally, of the remainder, 30% to the
limited partner and 70% to the general partner. In 1997, the Georgia park
contributed $    million of Six Flags' EBITDA, representing     % thereof.
 
    SIX FLAGS OVER TEXAS AND SIX FLAGS HURRICANE HARBOR
 
    Six Flags Over Texas, the 16th largest theme park in the United States with
1997 attendance of 2.9 million, and the separately gated Six Flags Hurricane
Harbor, the 7th largest water park in the United States with 1997 attendance of
558,000, are located across Interstate 30 from each other in Arlington, Texas,
between Dallas and Fort Worth, Texas. The Dallas/Fort Worth market provides the
parks with a permanent resident population of     million people within 50 miles
and     million people within 100 miles. The Dallas/Fort Worth market is the
number 8 DMA in the United States. Based upon in-park surveys, approximately
    % of the visitors to the parks in 1997 resided within a 50-mile radius of
the park, and     % resided within a 100-mile radius.
 
                                       38
<PAGE>
    Six Flags Hurricane Harbor includes a year-round family entertainment center
named "Funsphere," which includes a laser tag facility, a games arcade, two
go-cart tracks, a miniature golf course, batting cages and other attractions.
Funsphere does not charge front gate admission; attractions are offered on a
pay-as-you-play basis.
 
    The Texas Co-Venture Partnership (defined below) owns the site of
approximately 197 acres used for the theme park, and the Company owns
approximately an additional 49 acres, of which approximately 18 acres are
currently used for Hurricane Harbor, seven acres are used for Funsphere (an
adjacent family entertainment center), and 22 acres remain undeveloped. Six
Flags Over Texas' principal competitors include Sea World of Texas and the
Company's Six Flags Fiesta Texas, both located in San Antonio, Texas,
approximately   miles from the park. Six Flags Hurricane Harbor has no direct
competitors in the area.
 
    PARTNERSHIP STRUCTURE.  Six Flags Over Texas is owned by Texas Flags, Ltd.
(the "Texas Co-Venture Partnership"), a Texas limited partnership of which the
1% general partner is a wholly-owned subsidiary of Six Flags, and the 99%
limited partner is Six Flags Over Texas Fund, Ltd., a Texas limited partnership
(the "Texas Limited Partner") which is unaffiliated with Six Flags. Under the
terms of the prior partnership agreement, the Texas Partnership was scheduled to
dissolve on December 31, 1997, unless 66 2/3% of the Texas Investors voted in
favor of continuing the partnership. In connection with the Six Flags
Transactions, SFEC will transfer its interests in Six Flags Over Texas to
Premier.
 
    In December 1997, Six Flags completed arrangements (the "Texas Agreements")
pursuant to which it will manage Six Flags Over Texas through 2027. The key
elements of the new arrangements are as follows: (i) the Texas Limited Partner
will receive minimum annual distributions of $27.7 million in 1998, increasing
each year thereafter in proportion to increases in the cost of living; (ii)
thereafter, Six Flags will be entitled to receive from available cash (after
provision for reasonable reserves and after capital expenditures per annum of
approximately 6.0% of prior year's revenues) a management fee equal to 3% of the
prior year's gross revenues, and, thereafter, any additional available cash will
be distributed 92.5% to Six Flags and 7.5% to the Texas Limited Partner; (iii)
in the first quarter of 1998, Six Flags made a tender offer for partnership
units ("LP Units") in the Texas Limited Partner that values the park at the
greater of approximately $374.8 million or 8.5 times 1997 EBITDA of the park
(the "Tender Offer Price"); (iv) commencing in 1999, and on an annual basis
thereafter, Six Flags will offer to purchase LP Units at a price based on a
valuation for the park equal to the greater of $374.8 million or a value derived
by multiplying the weighted-average four year EBITDA of the park by 8.5; (v) in
2027 Six Flags and its affiliates will have the option to acquire all remaining
interests in the park at a price based on the Tender Offer Price, increased in
proportion to the increase in the cost of living between December 1997 and
December 2027; and (vi) the Company is required to make minimum capital
expenditures at the Texas park during rolling five-year periods, based generally
on 6% of such park's revenues. Cash flow from operations at the Texas park will
be used to satisfy these requirements first, before any funds are required from
the Company. Six Flags purchased approximately    % of the LP units in the 1998
tender offer at an aggregate price of $         million. In connection with the
Subordinate Indemnity Agreement, the Company is transferring to Time Warner (who
has guaranteed the Six Flags obligations under these arrangements) record title
to certain entities that have purchased and will purchase LP Units and the
Company will receive an assignment from Time Warner of all cash flow received on
such LP Units and will otherwise control such entities, except in the event of a
default by the Company of its obligations under these arrangements. After all
such obligations have been satisfied, Time Warner is required to transfer to the
Company such stock for a nominal consideration. In addition, the Company will
issue preferred stock of the managing partner of the Texas Co-Venture
Partnership to Time Warner which, in the event of such a default, would permit
Time Warner to obtain control of such entity. See "Description of Six Flags
Agreement."
 
    Six Flags has accounted for the park as a co-venture and included the
revenues and expenses of the Texas Co-Venture Partnership (excluding partnership
depreciation and interest expense associated with limited partnership debt) in
its consolidated financial statements and deducted as expenses the net
 
                                       39

amounts distributed to the Texas Limited Partner. Under the previous partnership
agreement for the Texas Co-Venture Partnership, net cash flow (as defined in the
partnership agreement) is distributed 30% to the limited partner and 70% to the
general partner. The 70%--30% split became effective after the limited partner
received cumulative net cash flow distributions from the Texas Co-Venture
Partnership subsequent to its formation equal to an aggregate amount of $110
million. In 1997, the park contributed $    million of Six Flags' EBITDA,
representing     % thereof.
 
    SIX FLAGS ST. LOUIS
 
    Six Flags St. Louis, the 33rd largest theme park in the United States with
1997 attendance of 1.7 million, is located in Eureka, Missouri, about 35 miles
west of St. Louis, Missouri. The St. Louis market provides the park with a
permanent resident population of     million people within 50 miles and
million people within 100 miles. The St. Louis market is the number 21 DMA in
the United States. Based upon in-park surveys, approximately     % of the
visitors to the park in 1997 resided within a 50-mile radius of the park, and
    % resided within a 100-mile radius.
 
    The Company owns a site of approximately 499 acres used for the theme park
operations. Six Flags St. Louis competes with Paramount's Kings Island, located
near Cincinnati, Ohio, approximately 350 miles from the park; Cedar Point,
located in Sandusky, Ohio, approximately 515 miles from the park; Silver Dollar
City, located in Branson, Missouri, approximately 250 miles from the park, and
Six Flags Great America, the Company's park located near Chicago, Illinois,
approximately 320 miles from the park.
 
MARKETING AND PROMOTION
 
    The Company attracts visitors through national and local multi-media
marketing and promotional programs for each of its parks. The national programs
are designed to market and enhance the Six Flags brand name. Local programs are
tailored to address the different characteristics of their respective markets
and to maximize the impact of specific park attractions and product
introductions. All marketing and promotional programs are updated or completely
revamped each year to address new developments. Following the Six Flags
Acquisition, marketing programs for the Six Flags Parks will be supervised by
Premier's Vice President for Marketing, with the assistance of Premier's senior
management and its national advertising agency.
 
    The Company also develops partnership relationships with well-known national
and regional consumer goods companies and retailers to supplement its
advertising efforts and to provide attendance incentives in the form of
discounts and/or premiums.
 
    Group sales and pre-sold tickets provide the Company with a consistent and
stable base of attendance, representing approximately    % of aggregate
attendance in 1997. Each park has a group sales and pre-sold ticket manager and
a well-trained sales staff dedicated to selling multiple group sales and
pre-sold ticket programs through a variety of methods, including direct mail,
telemarketing and personal sales calls.
 
    The Company has also developed effective programs for marketing season pass
tickets. Season pass sales establish a solid attendance base in advance of the
season, thus reducing exposure to inclement weather. Additionally, season pass
holders often bring paying guests and generate "word-of-mouth" advertising for
the parks. The increased in-park spending which results from season passes is
not offset by incremental operating expenses, since such expenses are relatively
fixed during the operating season. During 1997,    % of visitors to the Six
Flags Parks utilized season passes.
 
    A significant portion of the Company's attendance is attributable to the
sale of discount admission tickets. The Company offers discounts on season and
multi-visit tickets, tickets for specific dates and tickets to affiliated groups
such as businesses, schools and religious, fraternal and similar organizations.
The increased in-park spending which results from such attendance is not offset
by incremental operating expenses, since such expenses are relatively fixed
during the operating season. In 1997, approximately
 
                                       40
<PAGE>
   % of patrons at the Six Flags Parks were admitted at a discount rate and, for
the year ended December 31, 1997, approximately    % of the Company's revenue
was attributable to in-park spending.
 
    The Company also implements promotional programs as a means of targeting
specific market segments and geographic locations not reached through its group
or retail sales efforts. The promotional programs utilize coupons, sweepstakes,
reward incentives and rebates to attract additional visitors. These programs are
implemented through direct mail, telemarketing, direct response media,
sponsorship marketing and targeted multi-media programs. The special promotional
offers are usually for a limited time and offer a reduced admission price or
provide some additional incentive to purchase a ticket, such as combination
tickets with a complementary location.
 
LICENSES
 
    Six Flags currently has, and pursuant to the License Agreement Premier will
have upon consummation of the Six Flags Acquisition, the exclusive right for a
term through 2053 to use Warner Bros. and DC Comics characters in theme parks
throughout the United States and Canada (other than the Las Vegas metropolitan
area). In particular, the License Agreement entitles Six Flags and Premier to
use, subject to customary approval rights of Warner Bros., and in limited
circumstances, approval rights of certain third parties, all animated cartoon
and comic book characters that Warner Bros. and DC Comics have the right to
license, including as of the date hereof, BATMAN, SUPERMAN, BUGS BUNNY, DAFFY
DUCK, TWEETY BIRD and YOSEMITE SAM, and will include the right to sell
merchandise using the characters. The license fee is fixed until 2005, and
thereafter, the license fee will be subject to periodic scheduled increases and
will be payable on a per-theme park basis. Six Flags is also a party to certain
additional license agreements with Warner Bros. and Time Warner concerning,
among others, HBO BACKLOT COMMISSARY and SPORTS ILLUSTRATED FESTIVAL. Warner
Bros. has the right to terminate the License Agreement if any persons involved
in the movie or television industries or party to a material judicial proceeding
pending against Time Warner obtain control of Premier.
 
PARK OPERATIONS
 
    The Company currently operates in geographically diverse markets in the
United States. After the Six Flags Acquisition, each of the Company's parks will
be operated to the extent practicable as a separate operating division of the
Company in order to maximize local marketing opportunities and to provide
flexibility in meeting local needs. After the Six Flags Acquisition, each park
will be managed by a general manager who will report to one of Premier's [three]
Executive Vice Presidents (each of whom report to its Chief Operating Officer)
and will be responsible for all operations and management of the individual
park. Local advertising, ticket sales, community relations and hiring and
training of personnel are the responsibility of individual park management in
coordination with corporate support teams.
 
    Each of the Company's parks is managed by a full-time, on-site management
team under the direction of the general manager. Each such management team
includes senior personnel responsible for operations and maintenance, marketing
and promotion, human resources and merchandising. Park management compensation
structures will be designed to provide incentives (including stock options and
cash bonuses) for individual park managers to execute Premier's strategy and to
maximize revenues and operating cash flow at each park.
 
    The Company's parks are generally open daily from Memorial Day through Labor
Day. In addition, most of the Company's parks are open during weekends prior to
and following their daily seasons, primarily as a site for theme events (such as
Fright Fest-Registered Trademark- and Holiday in the
Park-Registered Trademark-). Typically, the parks charge a basic daily admission
price, which allows unlimited use of all rides and attractions, although in
certain cases special rides and attractions require the payment of an additional
fee.
 
                                       41
<PAGE>
CAPITAL IMPROVEMENTS
 
    The Company regularly makes capital investments in the development and
implementation of new rides and attractions at its parks. In addition, the
Company may at times rotate rides among its parks to provide fresh attractions.
Premier believes that the introduction of new rides is an important factor in
promoting each of the parks in order to promote market penetration and encourage
longer visits, which lead to increased attendance and in-park spending. In
addition, the Company utilizes theming and landscaping at its parks in order to
provide a complete family oriented entertainment experience. Capital
expenditures are planned on a seasonal basis with most expenditures made during
the off-season. Expenditures for materials and services associated with
maintaining assets, such as painting and inspecting rides are expensed as
incurred and therefore are not included in capital expenditures.
 
    The Company's level of capital expenditures are directly related to the
optimum mix of rides and attractions given park attendance and market
penetration. These targeted expenditures are intended to support significant
attendance at the parks and to provide an appropriate complement of
entertainment value, depending on the size of a particular market. As an
individual park begins to reach an appropriate attendance penetration for its
market, management generally plans a new ride or attraction every three to four
years in order to enhance the park's entertainment product. The Six Flags Parks
generally enjoy significant market penetration. As such, the Company anticipates
employing levels of capital expenditures necessary to sustain or incrementally
improve current levels of attendance.
 
MAINTENANCE AND INSPECTION
 
    The Company's rides are inspected daily by maintenance personnel during the
operating season. These inspections include safety checks, as well as regular
maintenance and are made through both visual inspection of the ride and test
operation. Senior management of Premier and the individual parks will evaluate
the risk aspects of each park's operation. Potential risks to employees and
staff as well as to the public are evaluated. Contingency plans for potential
emergency situations have been developed for each facility. During the
off-season, maintenance personnel examine the rides and repair, refurbish and
rebuild them where necessary. This process includes x-raying and magnafluxing (a
further examination for minute cracks and defects) steel portions of certain
rides at high-stress points. The Company has approximately       full-time
employees who devote substantially all of their time to maintaining the parks
and their rides and attractions.
 
    In addition to the Company's maintenance and inspection procedures,
Premier's liability insurance carrier performs an annual inspection of each park
and all attractions and related maintenance procedures. The result of insurance
inspections are written evaluation and inspection reports, as well as written
suggestions on various aspects of park operations. State inspectors also conduct
annual ride inspections before the beginning of each season. Other portions of
each park are also subject to inspections by local fire marshals and health and
building department officials. Furthermore, Premier uses Ellis & Associates as
water safety consultants at its parks in order to train life guards and audit
safety procedures.
 
EMPLOYEES
 
    The Company employs approximately       full-time employees and
approximately       seasonal employees during the operating season. In this
regard, the Company competes with other local employers for qualified student
and other candidates on a season-by-season basis. As part of the seasonal
employment program, the Company employs a significant number of teenagers, which
subjects the Company to child labor laws. The Company is not subject to federal
or certain applicable state minimum wage rates in respect of its seasonal
employees. However, the recent increase in the federal or any applicable state
minimum wage rate could result over time in increased compensation expense for
the Company as it relates to these employees as a result of competitive factors.
 
                                       42
<PAGE>
    Approximately    % of the Company's full-time and approximately    % of its
seasonal employees are subject to labor agreements with local chapters of
national unions. These labor agreements expire in                (Six Flags Over
Georgia and Six Flags Over Texas), December 1999 (Six Flags Great Adventure),
and January 2000 (Six Flags St. Louis). The Company has never experienced any
work stoppages, and believes that it has a strong relationship with its
employees and unions.
 
INSURANCE
 
    The Company maintains insurance of the type and in amounts that it believes
are commercially reasonable and that are available to businesses in its
industry. Six Flags maintains multi-layered general liability policies that
provide for excess liability coverage of up to $175.0 million per occurrence. By
virtue of self-insured retention limits ($500,000 per occurrence) and first
dollar coverage by a captive insurance company, Six Flags or its wholly-owned
insurance company subsidiary is required to pay the first $2 million of loss per
occurrence. Six Flags' combined cost for insurance and for self-insured claims
for 1997 was $         million compared to $         million in 1996 and
$         million in 1995. The Company also maintains fire and extended
coverage, workers' compensation, business interruption and other forms of
insurance typical to businesses in its industry. The fire and extended coverage
policies insure the Company's real and personal properties (other than land)
against physical damage resulting from a variety of hazards. Following the Six
Flags Acquisition, Premier may modify the insurance coverage applicable to the
Six Flags Parks.
 
LEGAL PROCEEDINGS
 
    The nature of the industry in which the Company operates tends to expose it
to claims by visitors for injuries. Historically, the great majority of these
claims have been minor. While the Company believes that it is adequately insured
against the claims currently pending against it and any potential liability, if
the number of such events resulting in liability significantly increased, or if
the Company becomes subject to damages that cannot by law be insured against,
such as punitive damages, there may be a material adverse effect on its
operations.
 
    On March 19, 1997, SFTP, and its wholly-owned subsidiary Six Flags Over
Georgia, Inc. (collectively, the "Six Flags Parties") commenced a declaratory
judgment action in the Superior Court of Gwinnett County, Georgia, entitled Six
Flags Over Georgia, Inc. and Six Flags Theme Parks, Inc. v. Six Flags Fund, Ltd.
and Avram Salkin, as Trustee of the Claims Trust. The Six Flags Parties sought,
among other things, a declaration and determination of the rights and
obligations of the partners of Six Flags Over Georgia, L.P., with respect to
certain disputed partnership affairs and an accounting of all partnership
affairs. On April 21, 1997, defendants Six Flags Fund, Ltd. and its affiliates
(collectively, the "SFOG Fund Parties") filed a motion to dismiss the
declaratory judgment action as well as an answer and counterclaim naming SFEC
and Time Warner Entertainment Company, L.P. as additional
counterclaim-defendants. The counterclaim seeks imposition of a constructive
trust and an accounting, compensatory damages of in excess of $250 million and
unspecified punitive damages for alleged breaches of fiduciary duty, conversion,
fraud and conspiracy allegedly committed by the counterclaim-defendants in
connection with the management of the Six Flags Over Georgia.
 
    On June 9, 1997, the parties entered into a Consent Order in which they
agreed, among other things, to realign the parties. An Amended Complaint was
then filed by the SFOG Fund Parties as the newly-aligned plaintiffs against the
Six Flags Parties in which the same substantive claims were asserted. The Six
Flags Parties filed their answer denying liability and asserting several
affirmative defenses on July 24, 1997. The Six Flags Parties intend to
vigorously contest the allegations of the complaint.
 
    The Sellers have agreed to indemnify Premier from any and all liabilities
arising from these proceedings.

<PAGE>
                       DESCRIPTION OF SIX FLAGS AGREEMENT
 
    GENERAL
 
    On February 9, 1998, the company presently named Premier Parks Inc., certain
wholly-owned subsidiaries of Premier, SFEC and each of the Sellers entered into
the Six Flags Agreement. The Six Flags Agreement provides for the Six Flags
Acquisition, pursuant to which Premier will acquire, by merger, all of the
capital stock of SFEC from the Sellers for an amount (such amount, the "Capital
Stock Consideration") equal to (i) $965 million, adjusted as described below
(the "Preliminary Base Amount"), MINUS (ii) the excess of the SFEC Option
Consideration (as defined below) over $5 million. The Capital Stock
Consideration will be payable in depositary shares representing interests in up
to $200 million, but not less than $100 million, of the Seller Preferred Stock,
with the balance payable in cash. The net proceeds of the Offerings will be
used, in part, to fund the cash portion of the Capital Stock Consideration.
Consummation of the Six Flags Acquisition is a condition to the Offerings.
 
    The Preliminary Base Amount will be adjusted as follows. If the actual
tangible net worth of SFEC as of the end of its 1997 fiscal year exceeds
$          (the estimated tangible net worth of SFEC as of the end of its 1997
fiscal year), the Preliminary Base Amount will be increased by an amount equal
to such excess. If, however, such actual tangible net worth is less than
$          , then the Preliminary Base Amount will be reduced accordingly.
 
    THE MERGERS
 
    Prior to the Six Flags Acquisition, and pursuant to the Premier Merger, the
company presently named Premier Parks Inc. will merge with a wholly-owned
subsidiary of Premier Parks Holdings Corporation in accordance with Section
251(g) of the Delaware General Corporation Law. As a result of the Premier
Merger, holders of shares of Common Stock of Premier will become, on a
share-for-share basis, holders of Common Stock of Premier Parks Holdings
Corporation, and Premier will become a wholly-owned subsidiary of Premier Parks
Holdings Corporation. On the effective date of the Premier Merger, Premier will
change its name to Premier Parks Operations Inc., and Premier Parks Holdings
Corporation will change its name to Premier Parks Inc.
 
    In addition to the share-for-share exchange, each option or similar right
exercisable for capital stock of Premier Operations outstanding immediately
prior to the Reorganization automatically will be converted into an option or
similar right exercisable for a number of shares of the Common Stock equal to
the number of shares of capital stock of Premier for which such option or
similar right was exercisable immediately prior to the Premier Merger.
 
    Immediately following the closing of the Offerings, SFEC and a wholly-owned
subsidiary of Premier will be merged pursuant to the Six Flags Acquisition, with
SFEC continuing as the surviving corporation and as a wholly-owned subsidiary of
Premier. Pursuant to the Six Flags Acquisition, (i) each share of capital stock
of SFEC outstanding immediately prior to the Six Flags Acquisition, all of which
are held by the Sellers, automatically will be converted into the right to
receive a pro rata share of the Capital Stock Consideration based on the
aggregate number of such shares (together with a cash payment in lieu of any
fractional shares of Seller Preferred Stock to which the Sellers would have
otherwise been entitled as part of the Capital Stock Consideration) and (ii)
each option or similar right exercisable for capital stock of SFEC outstanding
immediately prior to the Six Flags Acquisition automatically will be cancelled
in exchange for a cash payment by SFEC (all such cash payments together, the
"SFEC Option Consideration").
 
                                       44
<PAGE>
    CONDITIONS
 
    The Six Flags Agreement contains customary closing conditions of the
parties. In addition, the Six Flags Acquisition is subject to the condition that
Premier will raise equity capital in an amount at least equal to the difference
between $900.0 million and the value of the Seller Preferred Stock issued to the
Sellers pursuant to the Six Flags Acquisition.
 
    INDEMNIFICATION
 
    The Six Flags Agreement contains customary representations, warranties,
covenants and other agreements of the parties. The Sellers have agreed to
indemnify and hold harmless Premier against certain damages, claims and
liabilities (and the cost and expenses related thereto) suffered by Premier in
respect of (i) any breach of or inaccuracy in any representation or warranty
contained in the Six Flags Agreement made by any Seller individually, or by the
Sellers collectively, and (ii) any breach or violation of any covenant or
agreement made by any Seller for itself or on behalf of SFEC or its subsidiaries
contained in the Six Flags Agreement or any documents delivered at the closing
thereunder.
 
    Generally, no party may make a claim for indemnification for breaches of
representations and warranties and of covenants and other agreements as
described in the immediately preceding paragraph after the date (the "Claims
Termination Date") which is the earlier of (i) the 45th day following the date
on which audited annual financial statements of the Registrant and its
consolidated subsidiaries for the 1998 fiscal year are first made available to
the Registrant and (ii) April 30, 1999.
 
    Premier may not make any claims for indemnification for breaches of any of
the Sellers' representations and warranties until the aggregate amount of the
damages suffered exceeds $5 million (the "Basket Amount"), whereupon the Sellers
are obligated to pay in full all such amounts for indemnification, including the
Basket Amount. The total maximum amount that the Sellers are required to pay for
indemnification for breaches of the Sellers' representations and warranties
under the Six Flags Agreement is $25 million. Upon consummation of the Six Flags
Acquisition, Premier will deposit $25 million in cash into an escrow fund under
a General Indemnity Escrow Agreement to be entered into by the Company with the
Sellers and certain holders of options exercisable for capital stock of SFEC. A
portion of such deposit will come from the Capital Stock Consideration payable
to the Sellers, with the balance to come from the SFEC Option Consideration
payable to the optionholders party to the General Indemnity Escrow Agreement.
The escrow fund will be the sole source of payment for the Sellers'
indemnification obligations to the Company for breaches of or inaccuracies in
the Sellers' representations and warranties.
 
    In addition, the Sellers have agreed to indemnify and hold harmless Premier,
pursuant to the Georgia Litigation Indemnity Agreement being entered into at the
closing under the Six Flags Agreement, from any damages, claims and liabilities
(and the costs and expenses related thereto) suffered in connection with the
Georgia Litigation. See "Business--Legal Proceedings."
 
    AGREEMENTS RELATED TO THE SIX FLAGS AGREEMENT
 
    Certain ancillary agreements will be entered into pursuant to the Six Flags
Agreement in connection with the Six Flags Acquisition. See
"Business--Licenses."
 
    In addition to the ancillary agreements to be entered into in connection
with the Six Flags Acquisition that are described elsewhere herein, SFEC,
certain of SFEC's subsidiaries (together with SFEC, the "SFEC Parties"), Time
Warner, and Premier and a wholly-owned subsidiary of Premier (together, the
"Premier Parties") will enter into the Subordinate Indemnity Agreement. The
purpose of the Subordinate Indemnity Agreement is to have the SFEC Parties and
the Premier Parties provide support for certain payment and performance
obligations of Time Warner and SFEC Parties under the arrangements relating to
the Co-Venture Partnerships, the SFEC Zero Coupon Senior Notes and certain other
obligations. The obligations of Premier under the Subordinate Indemnity
Agreement rank senior to its obligations, under the Guarantee.

                   DESCRIPTION OF OTHER COMPANY INDEBTEDNESS
 
SIX FLAGS CREDIT FACILITY
 
    Borrowings under the Six Flags Credit Facility, which will be entered into
on or prior to the closing of the Six Flags Acquisition, will be secured by
substantially all of the assets of SFTP and its subsidiaries, and guaranteed by
such subsidiaries. The Six Flags Credit Facility will have an aggregate
availability of $472 million consisting of (i) up to $100.0 million under a
Revolving Credit Facility to be used to refinance existing outstanding Six Flags
bank indebtedness and for working capital and other general corporate purposes;
and (ii) up to $372.0 million under Facility B to be used to refinance existing
outstanding Six Flags bank indebtedness and fund acquisitions and make capital
improvements. The Company anticipates that Facility B will be fully funded in
connection with the Six Flags Acquisition. Interest rates per annum under the
Six Flags Credit Facility are equal to either (a) a base rate equal to the
higher of the Federal Funds Rate plus 1/2% or the prime rate of Citibank, N.A.,
in each case, plus the Applicable Margin (as defined therein) or (b) the London
Interbank Offered Rate plus the Applicable Margin. The Revolving Credit Facility
will terminate five years from the closing of the Six Flags Acquisition.
Borrowings under Facility B will mature on November 30, 2004. However, for
Facility B, aggregate principal payments and reductions of $1.0 million will be
required during each of the first, second, third and fourth years; aggregate
principal payments of $25.0 million and $40.0 million are required in years five
and six and $303.0 million in aggregate principal payments are required at
maturity.
 
    The Six Flags Credit Facility will contain restrictive covenants that, among
other things, limit the ability of SFTP and its subsidiaries to dispose of
assets; incur additional indebtedness or liens; pay dividends; repurchase stock;
make investments; engage in mergers or consolidations; and engage in certain
transactions with subsidiaries and affiliates. In addition, the Six Flags Credit
Facility will require SFTP to comply with certain specified financial ratios and
tests, including ratios of total debt to EBITDA, interest expense to EBITDA,
debt service to EBITDA and fixed charges to EBITDA.
 
    Defaults under the Six Flags Credit Facility will include (i) failure to
repay principal when due; (ii) failure to pay interest within three days after
due; (iii) default in the performance of certain obligations of SFTP's principal
subsidiaries under the Revolving Credit Security Agreement or any Equipment
Security Agreement (as defined thereunder); (iv) failure to comply with certain
covenants, conditions or agreements under the credit agreement which, in certain
cases, continues for 30 days; (v) default by SFTP or any of its principal
subsidiaries in respect of any indebtedness above specified levels; (vi) certain
events of bankruptcy; (vii) certain judgments against SFTP or any of its
principal subsidiaries; (viii) the occurrence of a Change in Control (as defined
thereunder); (ix) the assertion of certain Environmental Claims (as defined
thereunder); and (x) under certain circumstances, the failure by Messrs. Burke
and Story to serve as Chief Executive Officer and Chief Operating Officer of
SFTP and the failure to replace them within a specified time period.
 
SFTP SENIOR SUBORDINATED NOTES
 
    The SFTP Senior Subordinated Notes are unsecured senior subordinated
obligations of SFTP, in an aggregate principal amount of $285.0 million and will
mature on June 15, 2005. The SFTP Senior Subordinated Notes accrete in value
until June 15, 1998, at which time the accreted value will equal 100% of their
principal amount. The SFTP Senior Subordinated Notes bear interest at the rate
of 12 1/4% per annum, payable semiannually on June 15 and December 15 of each
year, commencing December 15, 1998.
 
    The SFTP Senior Subordinated Notes are redeemable, at SFTP's option, in
whole or in part, at any time on or after June 15, 2000 at specified redemption
prices, together with accrued and unpaid interest, if any, to the date of
redemption. Upon the occurrence of a Change of Control (as defined in the
applicable Indenture), SFTP is required to make an offer to repurchase the SFTP
Senior Subordinated Notes at a price equal to 101% of the principal amount
thereof, together with accrued and unpaid interest, if any, to
 
                                       46
<PAGE>
the date of repurchase. The Six Flags Transactions constitute a Change of
Control under the Indenture relating to the SFTP Senior Subordinated Notes, and
Premier will be required to make an offer to purchase the SFTP Senior
Subordinated Notes within 30 days of the closing of the Six Flags Transactions.
Premier does not expect that it will be required to purchase any material amount
of such Notes pursuant to such offer. See "Risk Factors--Risks Associated with
Substantial Indebtedness."
 
    The Indenture pursuant to which the SFTP Senior Subordinated Notes were
issued contains restrictive covenants that, among other things, limit the
ability of SFTP and its subsidiaries to dispose of assets; incur additional
indebtedness or liens; pay dividends; engage in mergers or consolidations; and
engage in certain transactions with subsidiaries and affiliates.
 
    Defaults under this Indenture include (i) failure to pay interest on the
SFTP Senior Subordinated Notes within 30 days after such payments are due; (ii)
failure to repay principal when due at its maturity date, upon optional
redemption, upon required repurchase, upon acceleration or otherwise; (iii)
failure to comply for 30 days after notice with SFTP's repurchase obligations
upon the occurrence of a Change of Control and failure to comply for 60 days
after notice with the other covenants contained in the Indenture; (iv) the
default by SFTP or any Significant Subsidiary (as defined in the applicable
Indenture) in respect of any indebtedness above specified levels; (v) certain
events of bankruptcy; (vi) certain judgments against SFTP or any Significant
Subsidiary; (vii) any Note Guarantee (as defined in the applicable Indenture)
ceasing to be in full force and effect (except as contemplated by the terms
thereof); and (viii) the denial or disaffirmation by any Note Guarantor of its
obligations under the applicable Indenture or any Note Guarantee, which
continues for 10 days.
 
SFEC ZERO COUPON SENIOR NOTES
 
    The SFEC Zero Coupon Senior Notes are senior unsecured obligations of SFEC,
in an aggregate principal amount of $192.25 million and will mature on December
15, 1999. The SFEC Zero Coupon Senior Notes accrete in value until December 15,
1999, at which time the accreted value will equal 100% of their principal
amount. There are no periodic payments on the SFEC Zero Coupon Senior Notes. One
of the Sellers has effectively guaranteed the SFEC Zero Coupon Senior Notes, and
the Company has indemnified that Seller in respect of its guarantee. The Company
will use the proceeds of the Offering, together with other funds, to provide for
the payment, at or prior to maturity of the SFEC Zero Coupon Senior Notes. Until
so used, such proceeds (or U.S. government obligations purchased from such
proceeds) will be deposited in escrow.
 
    The SFEC Zero Coupon Senior Notes may not be redeemed prior to maturity.
 
    From and after the consummation of the Six Flags Transaction, the
restrictive covenants contained in the indenture pursuant to which the SFEC Zero
Coupon Senior Notes were issued will generally not be applicable to SFEC or its
subsidiaries.
 
    Defaults under this indenture include (i) the failure by SFEC or Time Warner
to comply for 30 days after written notice with any covenant in the applicable
Indenture; (ii) failure to pay, when due, upon final maturity or upon
acceleration, the principal amount of any indebtedness of SFEC or any of its
subsidiaries in excess of $5.0 million, or any indebtedness of Time Warner or
any of its Material Subsidiaries (as defined in the applicable indenture) in
excess of $50 million, if such indebtedness is not discharged within 60 days
after written notice; (iii) certain events of bankruptcy of SFEC or Seller; and
(iv) failure to pay the principal amount of any SFEC Zero Coupon Senior Note at
its maturity date. Accordingly, after the Six Flags Acquisition, such a default
by Time Warner could result in the acceleration of the maturity of the SFEC Zero
Coupon Senior Notes.

                              DESCRIPTION OF NOTES
 
GENERAL
 
    The Notes will be issued pursuant to an Indenture (the "Indenture") between
the Company and       , as trustee (the "Trustee"). The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture
Act"). The Notes are subject to all such terms and Holders of Notes are referred
to the Indenture and the Trust Indenture Act for a statement thereof. The
following summary of the material provisions of the Indenture and the Pledge and
Escrow Agreement does not purport to be complete and is qualified in its
entirety by reference to the Indenture and the Pledge and Escrow Agreement,
including the definitions therein of certain terms used below. The proposed
forms of the Indenture and Pledge and Escrow Agreement have been filed as
exhibits to the Registration Statement of which this Prospectus is a part and
copies of the proposed forms of the Indenture and Pledge and Escrow Agreement
are available as set forth below under "--Additional Information." The
definitions of certain terms used in the following summary are set forth below
under "--Certain Definitions." For purposes of this summary, the term "Company"
refers only to Six Flags Entertainment Corporation and not to any of its
Subsidiaries and the term "Premier" refers only to Premier Parks Inc. and not to
any of its Subsidiaries.
 
    The Notes will be general unsecured obligations of the Company and will rank
PARI PASSU in right of payment with all future unsecured senior indebtedness of
the Company. However, the operations of the Company are conducted through its
Subsidiaries and, therefore, the Company is dependent upon the cash flow of its
Subsidiaries to meet its obligations, including its obligations under the Notes.
The Company's Subsidiaries will not be guarantors of the Notes. As a result, the
Notes will be effectively subordinated to all Indebtedness and other liabilities
and commitments (including trade payables) of the Company's Subsidiaries. Any
right of the Company to receive assets of any of its Subsidiaries upon the
latter's liquidation or reorganization (and the consequent right of the Holders
of the Notes to participate in those assets) will be effectively subordinated to
the claims of that Subsidiary's creditors, except to the extent that the Company
is itself recognized as a creditor of such Subsidiary, in which case the claims
of the Company would still be subordinate to any security in the assets of such
Subsidiary and any indebtedness of such Subsidiary senior to that held by the
Company. On a pro forma basis, as of December 31, 1997, the Company's
Subsidiaries would have had approximately $         million of Indebtedness
(including the SFTP Senior Subordinated Notes and borrowings under the Six Flags
Credit Facility) and $         million of trade payables and other liabilities
outstanding. See "Risk Factors--Holding Company Structure; Limitations on Access
to Cash Flow of Subsidiaries."
 
    As of the date of the Indenture, all of the Company's Subsidiaries will be
Restricted Subsidiaries. However, under certain circumstances, the Company will
be able to designate current or future Subsidiaries as Unrestricted
Subsidiaries. Unrestricted Subsidiaries will not be subject to many of the
restrictive covenants set forth in the Indenture.
 
ESCROW OF PROCEEDS
 
    Certain of the Company's obligations under the Notes will be secured pending
disbursement pursuant to the Pledge and Escrow Agreement by a pledge of the
Escrow Account. Approximately $      million will remain in the Escrow Account
and be used to effectively defease the SFEC Zero Coupon Senior Notes within
days of original issuance of the Notes and, prior to such defeasance, to
purchase a portfolio of Government Securities that will be pledged as security
for payments under the Notes.
 
    The Pledge and Escrow Agreement will provide for the grant by the Company to
the Trustee of a security interest in the Escrow Account for the benefit of the
Holders of the Notes. All such security interests will secure the payment and
performance when due of the Obligations of the Company under the Indenture and
under such Notes, as provided in the Pledge and Escrow Agreement. The ability of
holders to realize upon such funds or securities may be subject to certain
bankruptcy law limitations in the event of a bankruptcy of the Company.
 
                                       48
<PAGE>
    Pending such defeasance, all funds contained in the Escrow Account will be
invested in Government Securities. Upon the acceleration of the maturity of the
Notes or the failure to pay principal at maturity or upon certain redemptions
and repurchases of the Notes, the Pledge and Escrow Agreement will provide for
the foreclosure by the Trustee upon the net proceeds of the Escrow Account.
Under the terms of the Indenture, the proceeds of the Escrow Account shall be
applied, first, to amounts owing to the Trustee in respect of fees and expenses
of the Trustee and second, to the Obligations under the Notes and the Indenture.
 
    In the event of the Company's bankruptcy, the Company, as debtor in
possession under Chapter 11 of the Bankruptcy Code, would be entitled to
petition the United States Bankruptcy Court having jurisdiction over its case
for permission, under Section 363 of the Bankruptcy Code, to use the proceeds of
the Escrow Account to fund its operations during the pendency of the
reorganization proceedings. Permission for such use is likely to be granted so
long as the interests of the Trustee, for the benefit of the Holders of Notes
and itself as Trustee, are "adequately protected." A secured creditor's interest
in cash collateral to be used by a debtor in possession may be "adequately
protected" by, among other means, the granting of liens on substitute collateral
which may be substantially less liquid than Government Securities.
 
PRINCIPAL AND MATURITY OF AND INTEREST ON THE NOTES
 
    The Notes will be limited in aggregate principal amount to $170.0 million
and will mature on       , 2008. Interest on the Notes will accrue at the rate
of    % per annum and will be payable semi-annually in arrears on       and
      of each year, to Holders of record on the immediately preceding       and
      . Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from the date of
original issuance. Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months. Principal, premium, if any, and interest on
the Notes will be payable at the office or agency of the Company maintained for
such purpose within the City and State of New York or, at the option of the
Company, payment of interest may be made by check mailed to the Holders of the
Notes at their respective addresses set forth in the register of Holders of
Notes; PROVIDED that all payments of principal, premium and interest with
respect to Notes the Holders of which have given wire transfer instructions to
the Company will be required to be made by wire transfer of immediately
available funds to the accounts specified by the Holders thereof. Until
otherwise designated by the Company, the Company's office or agency in New York
will be the office of the Trustee maintained for such purpose. The Notes will be
issued in denominations of $1,000 and integral multiples thereof.
 
OPTIONAL REDEMPTION
 
    The Notes will not be redeemable at the Company's option prior to       ,
2003. Thereafter, the Notes will be subject to redemption at any time at the
option of the Company, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest thereon to the
applicable redemption date, if redeemed during the twelve-month period beginning
on       of the years indicated below:
 
<TABLE>
<CAPTION>
YEAR                                                                      PERCENTAGE
- ------------------------------------------------------------------------  -----------
<S>                                                                       <C>

</TABLE>
 
    Notwithstanding the foregoing, during the first 36 months after the date of
original issuance of the Notes, the Company may on any one or more occasions
redeem up to 35% of the aggregate principal amount of Notes originally issued
under the Indenture at a redemption price of    % of the principal amount
thereof on the redemption date with the net cash proceeds of one or more Public
Equity Offerings by (i) the Company or (ii) Premier to the extent the net cash
proceeds thereof are contributed to the
 
                                       49
<PAGE>
Company as a capital contribution to the common equity of the Company and/or the
net cash proceeds of a Strategic Equity Investment in (i) the Company or (ii)
Premier to the extent the net cash proceeds thereof are contributed to the
Company as a capital contribution to the common equity of the Company; PROVIDED
that in each case at least 65% of the aggregate principal amount of Notes
originally issued remains outstanding immediately after the occurrence of each
such redemption (excluding Notes held by the Company and its Subsidiaries); and
PROVIDED, FURTHER, that any such redemption shall occur within 45 days of the
date of the closing of each such Public Equity Offering and/or Strategic Equity
Investment.
 
SELECTION AND NOTICE
 
    If less than all of the Notes are to be redeemed at any time, selection of
such Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by
lot or by such method as the Trustee shall deem fair and appropriate; provided
that no Notes of $1,000 or less shall be redeemed in part.
 
    Notices of redemption shall be mailed by first class mail at least 30 but
not more than 60 days before the redemption date to each Holder of Notes to be
redeemed at its registered address. Notices of redemption may not be
conditional. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest ceases to
accrue on Notes or portions of them called for redemption.
 
MANDATORY REDEMPTION
 
    Except as set forth below under the caption "--Repurchase at the Option
Holders," the Company is not required to make mandatory redemption or sinking
fund payments with respect to the Notes.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
    CHANGE OF CONTROL
 
    Upon the occurrence of a Change of Control, the Company will be obligated to
make an offer (the "Change of Control Offer") to each Holder of Notes to
repurchase all or any part (equal to $1,000 or an integral multiple thereof) of
such Holder's Notes at an offer price in cash equal to 101% of the aggregate
principal amount thereof plus accrued and unpaid interest thereon, if any, to
the date of purchase. Within ten days following any Change of Control, the
Company will mail a notice to each Holder describing the transaction or
transactions that constitute the Change of Control and offering to repurchase
Notes pursuant to the procedures required by the Indenture and described in such
notice. The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes as a result of a Change of Control.
 
    On the Change of Control Payment Date, the Company will, to the extent
lawful, (1) accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (2) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Notes or
portions thereof so tendered and (3) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Company. The Paying Agent will promptly mail to each Holder of Notes so tendered
the Change of Control Payment for such Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a new Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; PROVIDED that each such new Note will be in a
 
                                       50
<PAGE>
principal amount of $1,000 or an integral multiple thereof. The Company will
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.
 
    The Indenture will provide that the Company will fix the Change of Control
Payment Date no earlier than 30 days and no later than 60 days after the Change
of Control Offer is mailed as set forth above. Prior to complying with the
provisions of the preceding sentence, but in any event within 90 days following
a Change of Control, the Company will either repay all outstanding Indebtedness
of its Subsidiaries or obtain the requisite consents, if any, under all
agreements governing all such outstanding Indebtedness of its Subsidiaries to
permit the repurchase of Notes required by this covenant. Under the terms of the
indenture governing the SFTP Senior Subordinated Notes and the Six Flags Credit
Facility, the payment of dividends by SFTP are subject to certain specified
financial tests which will significantly restrict its ability to pay dividends
or make other distributions. If the Company does not obtain the consent of the
lenders under agreements governing outstanding Indebtedness of its Subsidiaries,
including under the Six Flags Credit Facility and the indenture governing the
SFTP Senior Subordinated Notes, to permit the repurchase of Notes or does not
refinance such Indebtedness, the Company will likely not have the financial
resources to purchase Notes and the Company's Subsidiaries will be restricted by
the terms of such Indebtedness from paying dividends to the Company or otherwise
lending funds to the Company for the purpose of such purchase. In any event,
there can be no assurance that the Company's Subsidiaries will have the
resources available to pay any such dividend or make any such distribution. The
Company's failure to make a Change of Control Offer when required or to purchase
tendered Notes when tendered would constitute an Event of Default under the
Indenture. See "Risk Factors--Holding Company Structure; Limitations on Access
to Cash Flow of Subsidiaries" and "--Risks Associated with a Change of Control."
 
    The Change of Control provisions described above will be applicable whether
or not any other provisions of the Indenture are applicable. Except as described
above with respect to a Change of Control, the Indenture does not contain
provisions that permit the Holders of the Notes to require that the Company
repurchase or redeem the Notes in the event of a takeover, recapitalization or
similar transaction.
 
    The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in the Indenture applicable to a Change of Control Offer made by the Company and
purchases all Notes validly tendered and not withdrawn under such Change of
Control Offer.
 
    The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of the Company and its Subsidiaries taken as a whole. Although
there is a developing body of case law interpreting the phrase "substantially
all," there is no precise established definition of the phrase under applicable
law. Accordingly, the ability of a Holder of Notes to require the Company to
repurchase such Notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of the assets of the Company and its
Subsidiaries taken as a whole to another Person or group may be uncertain.
 
    ASSET SALES
 
    The Indenture will provide that the Company will not, and will not permit
any of its Restricted Subsidiaries to, consummate an Asset Sale unless (i) the
Company (or the Restricted Subsidiary, as the case may be) receives
consideration at the time of such Asset Sale at least equal to the fair market
value (evidenced by a resolution of the Board of Directors set forth in an
Officers' Certificate delivered to the Trustee) of the assets or Equity
Interests issued or sold or otherwise disposed of and (ii) at least 75% of the
consideration therefor received by the Company or such Restricted Subsidiary is
in the form of cash; PROVIDED that the amount of (x) any liabilities (as shown
on the Company's or such Restricted Subsidiary's most recent balance sheet), of
the Company or any Restricted Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the Notes or any guarantee
thereof) that are assumed
 
                                       51
<PAGE>
by the transferee of any such assets pursuant to a customary novation agreement
that releases the Company or such Restricted Subsidiary from further liability
and (y) any securities, notes or other obligations received by the Company or
such Restricted Subsidiary from such transferee that are contemporaneously
(subject to ordinary settlement periods) converted by the Company or such
Restricted Subsidiary into cash (to the extent of the cash received), shall be
deemed to be cash for purposes of this provision.
 
    Within 365 days after the receipt of any Net Proceeds from an Asset Sale,
the Company or the applicable Restricted Subsidiary may apply such Net Proceeds
(a) to repay Indebtedness of a Restricted Subsidiary of the Company (and to
correspondingly reduce commitments with respect thereto in the case of revolving
credit borrowings) or (b) to the acquisition of all or substantially all of the
assets of, or a majority of the Voting Stock of, another Permitted Business, (c)
to the making of a capital expenditure or (d) to the acquisition of other
long-term assets that are used or useful in a Permitted Business. Pending the
final application of any such Net Proceeds, the Company or such Restricted
Subsidiary may temporarily reduce revolving credit borrowings or otherwise
invest such Net Proceeds in any manner that is not prohibited by the Indenture.
Any Net Proceeds from Asset Sales that are not applied or invested as provided
in the first sentence of this paragraph will be deemed to constitute "Excess
Proceeds." When the aggregate amount of Excess Proceeds exceeds $    million,
the Company will be required to make an offer to all Holders of Notes and all
holders of other PARI PASSU Indebtedness containing provisions similar to those
set forth in the Indenture with respect to offers to purchase or redeem with the
proceeds of sales of assets (an "Asset Sale Offer") to purchase the maximum
principal amount of Notes and such other PARI PASSU Indebtedness that may be
purchased out of the Excess Proceeds, at an offer price in cash in an amount
equal to 100% of the principal amount thereof plus accrued and unpaid interest
thereon, if any, to the date of purchase, in accordance with the procedures set
forth in the Indenture and such other Indebtedness. To the extent that any
Excess Proceeds remain after consummation of an Asset Sale Offer, the Company
may use such Excess Proceeds for any purpose not otherwise prohibited by the
Indenture. If the aggregate principal amount of Notes and such other
Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Trustee shall select the Notes and such other Indebtedness to be
purchased on a pro rata basis. Upon completion of such offer to purchase, the
amount of Excess Proceeds shall be reset at zero.
 
    The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to an Asset Sale Offer.
 
    Under the terms of the indenture governing the SFTP Senior Subordinated
Notes and the Six Flags Credit Facility, the payment of dividends by SFTP are
subject to certain specified financial tests which will significantly restrict
its ability to pay dividends or make other distributions. If the Company does
not obtain the consent of the lenders under agreements governing outstanding
Indebtedness of its Subsidiaries, including under the Six Flags Credit Facility
and the indenture governing the SFTP Senior Subordinated Notes, to permit the
repurchase of Notes or does not refinance such Indebtedness, the Company will
likely not have the financial resources to purchase Notes and the Company's
Subsidiaries will be restricted by the terms of such Indebtedness from paying
dividends to the Company or otherwise lending funds to the Company for the
purpose of such purchase. In any event, there can be no assurance that the
Company's Subsidiaries will have the resources available to pay any such
dividend or make any such distribution. The Company's failure to make an Asset
Sale Offer when required or to purchase tendered Notes when tendered would
constitute an Event of Default under the Indenture. See "Risk Factors--Risks
Associated with Substantial Indebtedness" and "--Holding Company Structure;
Limitations on Access to Cash Flow of Subsidiaries."

<PAGE>
CERTAIN COVENANTS
 
    RESTRICTED PAYMENTS
 
    The Indenture will provide that the Company will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly: (i) declare or
pay any dividend or make any other payment or distribution on account of any
Equity Interests of the Company (including, without limitation, any payment in
connection with any merger or consolidation involving the Company) or to the
direct or indirect holders of any Equity Interests of the Company in their
capacity as such (other than dividends or distributions payable in Equity
Interests (other than Disqualified Stock) of the Company); (ii) purchase, redeem
or otherwise acquire or retire for value (including, without limitation, in
connection with any merger or consolidation involving the Company) any Equity
Interests of the Company or any direct or indirect parent of the Company; (iii)
make any payment on or with respect to, or purchase, redeem, defease or
otherwise acquire or retire for value any Indebtedness of the Company that is
subordinated to the Notes, except a payment of interest or principal at Stated
Maturity; or (iv) make any Restricted Investment (all such payments and other
actions set forth in clauses (i) through (iv) above being collectively referred
to as "Restricted Payments"), unless, at the time of and after giving effect to
such Restricted Payment:
 
        (a) no Default or Event of Default shall have occurred and be continuing
    or would occur as a consequence thereof; and
 
        (b) the Company would, at the time of such Restricted Payment and after
    giving pro forma effect thereto as if such Restricted Payment had been made
    at the beginning of the applicable four-quarter period, have been permitted
    to incur at least $1.00 of additional Indebtedness pursuant to the Debt to
    Cash Flow test set forth in the first paragraph of the covenant described
    below under caption "-- Incurrence of Indebtedness and Issuance of Preferred
    Stock;" and
 
        (c) such Restricted Payment, together with the aggregate amount of all
    other Restricted Payments declared or made after the date of the Indenture
    (excluding Restricted Payments permitted by clauses (ii) and (iii) of the
    next succeeding paragraph) shall not exceed, at the date of determination,
    the sum, without duplication, of (i) an amount equal to the Company's
    Consolidated Cash Flow for the period (taken as one accounting period) from
    the beginning of the first fiscal quarter commencing after the date of the
    Indenture to the end of the Company's most recently ended full fiscal
    quarter for which internal financial statements are available (the "Basket
    Period") LESS the product of     times the Company's Consolidated Interest
    Expense for the Basket Period, PLUS (ii) 100% of the aggregate net cash
    proceeds received by the Company after the date of the Indenture as a
    contribution to its common equity capital or from the issue or sale of
    Equity Interests of the Company (other than Disqualified Stock) or from the
    issue or sale after the date of the Indenture of Disqualified Stock or debt
    securities of the Company that have been converted into such Equity
    Interests (other than Equity Interests (or Disqualified Stock or convertible
    debt securities) sold to a Subsidiary of the Company and other than in, or
    with the proceeds of, the Offerings), PLUS (iii) to the extent that any
    Restricted Investment that was made after the date of the Indenture is sold
    for cash or otherwise liquidated or repaid for cash, the lesser of (A) the
    cash return of capital with respect to such Restricted Investment (less the
    cost of disposition, if any) and (B) the initial amount of such Restricted
    Investment, PLUS (iv) to the extent that any Unrestricted Subsidiary is
    redesignated as a Restricted Subsidiary after the date of the Indenture, the
    fair market value of the Issuer's Investment in such Subsidiary as of the
    date of such redesignation.
 
    The foregoing provisions will not prohibit:
 
        (i) the payment of any dividend within 60 days after the date of
    declaration thereof, if at said date of declaration such payment would have
    complied with the provisions of the Indenture;
 
        (ii) the redemption, repurchase, retirement, defeasance or other
    acquisition of any subordinated Indebtedness or Equity Interests of the
    Company in exchange for, or out of the net cash proceeds of
 
                                       53
<PAGE>
    the substantially concurrent sale (other than to a Subsidiary of the
    Company) of, Equity Interests of the Company (other than Disqualified
    Stock); PROVIDED that the amount of any such net cash proceeds that are
    utilized for any such redemption, repurchase, retirement, defeasance or
    other acquisition shall be excluded from clause (c)(ii) of the preceding
    paragraph;
 
        (iii) the defeasance, redemption, repurchase or other acquisition of
    subordinated Indebtedness with the net cash proceeds from an incurrence of
    Permitted Refinancing Indebtedness;
 
        (iv) so long as no Event of Default or Default shall have occurred and
    be continuing (or would result therefrom), (a) the purchase, redemption,
    retirement or other acquisition by the Company or any Restricted Subsidiary
    of the Company of limited partnership interests held by the limited partners
    in the Co-Venture Partnerships, or their successors, in accordance with and
    in the manner required by the terms of the Partnership Park Agreements as
    the same are in effect on the date of the Indenture and (b) dividends or
    other distributions to Premier to enable Premier to purchase, redeem, retire
    or otherwise acquire limited partnership interests held by the limited
    partners in the Co-Venture Partnerships, or their successors, in accordance
    with and in the manner required by the terms of the Partnership Park
    Agreements as the same are in effect on the date of the Indenture;
 
        (v) so long as no Event of Default or Default shall have occurred and be
    continuing (or would result therefrom), any transactions pursuant to and
    payments in connection with, and, in each case, in accordance with, the
    terms of the Partnership Park Agreements as the same are in effect on the
    date of the Indenture;
 
        (vi) so long as no Event of Default or Default shall have occurred and
    be continuing (or would result therefrom), the payment of dividends or other
    distributions to Premier to enable Premier to pay dividends on the Seller
    Preferred Stock in accordance with the terms thereof as in effect on the
    date of the Indenture; and
 
        (vii) the repurchase, redemption or other acquisition or retirement for
    value of any Equity Interests of the Company from employees, former
    employees, directors or former directors of the Company or any of its
    Restricted Subsidiaries (or permitted transferees of such employees, former
    employees, directors or former directors); PROVIDED, HOWEVER, that the
    aggregate amount of such repurchases shall not exceed $   million in any
    twelve-month period.
 
    The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default; PROVIDED
that in no event shall the business currently operated by SFTP be transferred to
or held by an Unrestricted Subsidiary. For purposes of making such
determination, all outstanding Investments held by the Company and its
Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary
so designated will be deemed to be Restricted Payments at the time of such
designation and will reduce the amount available for Restricted Payments under
the first paragraph of this covenant. All such outstanding Investments will be
deemed to constitute Investments in an amount equal to the fair market value of
such Investments at the time of such designation. Such designation will only be
permitted if such Restricted Payment would be permitted at such time and if such
Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary.
 
    The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Subsidiary, as the
case may be, pursuant to the Restricted Payment. The fair market value of any
non-cash Restricted Payment shall be determined by the Board of Directors of the
Company whose resolution with respect thereto shall be delivered to the Trustee,
such determination to be based upon an opinion or appraisal issued by an
accounting, appraisal or investment banking firm of national standing if such
fair market value exceeds $    million. Not later than the date of making any
Restricted Payment, the Company shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by the covenant "Restricted
 
                                       54
<PAGE>
Payments" were computed, together with a copy of any fairness opinion or
appraisal required by the Indenture.
 
    INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK
 
    The Indenture will provide that the Company will not, and will not permit
any of its Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness (including Acquired Debt) and that the Company will not issue any
Disqualified Stock and will not permit any of its Subsidiaries to issue any
shares of preferred stock; PROVIDED, HOWEVER, that the Company may incur
Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock if
the Company's Debt to Cash Flow Ratio at the time of incurrence of such
Indebtedness or the issuance of such Disqualified Stock or such preferred stock,
as the case may be, after giving pro forma effect to such incurrence or issuance
as of such date and to the use of the proceeds therefrom as if the same had
occurred at the beginning of the most recently ended four full fiscal quarter
period of the Company for which internal financial statements are available,
would have been no greater than (a)       to 1, if such incurrence or issuance
is on or prior to       ,     , and (b)       to 1, if such incurrence or
issuance is after       ,     .
 
    The Indenture will also provide that the Company will not incur any
Indebtedness that is contractually subordinated in right of payment to any other
Indebtedness of the Company unless such Indebtedness is also contractually
subordinated in right of payment to the Notes on substantially identical terms;
PROVIDED, HOWEVER, that no Indebtedness of the Company shall be deemed to be
contractually subordinated in right of payment to any other Indebtedness of the
Company solely by virtue of being unsecured.
 
    The provisions of the first paragraph of this covenant will not apply to the
incurrence of any of the following items of Indebtedness (collectively,
"Permitted Debt"):
 
        (i) the incurrence by the Company and its Restricted Subsidiaries of
    term Indebtedness under Credit Facilities; PROVIDED that the aggregate
    principal amount of all term Indebtedness outstanding under all Credit
    Facilities after giving effect to such incurrence does not exceed an amount
    equal to $         million LESS the aggregate amount of all mandatory or
    scheduled repayments by the Company or any of its Restricted Subsidiaries of
    the principal of any term Indebtedness under a Credit Facility (other than
    repayments that are immediately reborrowed) that have been made since the
    date of the Indenture;
 
        (ii) the incurrence by the Company and its Restricted Subsidiaries of
    revolving credit Indebtedness and letters of credit pursuant to Credit
    Facilities; PROVIDED that the aggregate principal amount of all revolving
    credit Indebtedness and letters of credit (with letters of credit being
    deemed to have a principal amount equal to the maximum potential liability
    of the Company and its Restricted Subsidiaries thereunder) outstanding under
    all Credit Facilities of the Company and its Restricted Subsidiaries after
    giving effect to such incurrence does not exceed $         million LESS the
    aggregate amount of all commitment reductions by the Company or any of its
    Restricted Subsidiaries with respect to revolving credit borrowings that
    have been made since the date of the Indenture as a result of the
    application of Net Proceeds of Asset Sales pursuant to the covenant
    described above under the caption "--Repurchase at the Option of Holders
    Asset Sales" and, PROVIDED FURTHER, that the aggregate principal amount of
    all Indebtedness incurred pursuant to this clause (ii) is reduced to an
    outstanding balance of $1.0 million or less for at least 30 consecutive days
    in each fiscal year;
 
        (iii) the incurrence by the Company and its Restricted Subsidiaries of
    the Existing Indebtedness;
 
        (iv) the incurrence by the Company of Indebtedness represented by the
    Notes;
 
        (v) the incurrence by the Company or any of its Restricted Subsidiaries
    of Indebtedness represented by Capital Lease Obligations, mortgage
    financings or purchase money obligations, in each case incurred for the
    purpose of financing all or any part of the purchase price or cost of
    construction or improvement of property, plant or equipment used in the
    business of the Company or such
 
                                       55
<PAGE>
    Restricted Subsidiary, in an aggregate principal amount not to exceed
    $         million at any time outstanding;
 
        (vi) the incurrence by the Company or any of its Restricted Subsidiaries
    of Permitted Refinancing Indebtedness in exchange for, or the net proceeds
    of which are used to refund, refinance or replace Indebtedness (other than
    intercompany Indebtedness and Indebtedness incurred pursuant to clauses (i)
    and (ii) above) that was permitted by the Indenture to be incurred;
 
        (vii) the incurrence by the Company or any of its Restricted
    Subsidiaries of intercompany Indebtedness between or among the Company and
    any of its Restricted Subsidiaries; PROVIDED, HOWEVER, that (i) if the
    Company is the obligor on such Indebtedness, such Indebtedness is expressly
    subordinated to the prior payment in full in cash of all Obligations with
    respect to the Notes and (ii)(A) any subsequent issuance or transfer of
    Equity Interests that results in any such Indebtedness being held by a
    Person other than the Company or a Restricted Subsidiary thereof and (B) any
    sale or other transfer of any such Indebtedness to a Person that is not
    either the Company or a Restricted Subsidiary thereof shall be deemed, in
    each case, to constitute an incurrence of such Indebtedness by the Company
    or such Restricted Subsidiary, as the case may be, that was not permitted by
    this clause (vii);
 
        (viii) the incurrence by the Company or any of its Restricted
    Subsidiaries of (a) Hedging Obligations that are incurred for the purpose of
    fixing or hedging interest rate risk with respect to any floating rate
    Indebtedness that is permitted by the terms of the Indenture to be incurred
    and (b) Currency Agreements that do not increase the Indebtedness of the
    Company and its Restricted Subsidiaries outstanding at any time other than
    as a result of fluctuations in foreign currency exchange rates or interest
    rates or by reason of fees, indemnities and compensation payable thereunder;
 
        (ix) Indebtedness in respect of performance bonds, letters of credits,
    surety or appeal bonds, prior to any drawing thereunder, for or in
    connection with pledges, deposits or payments made or given in the ordinary
    course of business;
 
        (x) the guarantee by the Company or any of its Restricted Subsidiaries
    of Indebtedness of the Company or a Restricted Subsidiary of the Company
    that was permitted to be incurred by another provision of this covenant
    (including, without limiting the generality of the forgoing, the guarantee
    by any Restricted Subsidiary of the Company of Existing Indebtedness);
 
        (xi) the incurrence by the Company's Unrestricted Subsidiaries of
    Non-Recourse Debt, PROVIDED, HOWEVER, that if any such Indebtedness ceases
    to be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be
    deemed to constitute an incurrence of Indebtedness by a Restricted
    Subsidiary of the Company that was not permitted by this clause (xi); and
 
        (xii) the incurrence by the Company or any of its Restricted
    Subsidiaries of additional Indebtedness in an aggregate principal amount (or
    accreted value, as applicable) at any time outstanding, including all
    Permitted Refinancing Indebtedness incurred to refund, refinance or replace
    any Indebtedness incurred pursuant to this clause (xii), not to exceed
    $         million.
 
    For purposes of determining compliance with this covenant, in the event that
an item of Indebtedness meets the criteria of more than one of the categories of
Permitted Debt described in clauses (i) through (xii) above or is entitled to be
incurred pursuant to the first paragraph of this covenant, the Company shall, in
its sole discretion, classify such item of Indebtedness in any manner that
complies with this covenant and such item of Indebtedness will be treated as
having been incurred pursuant to only one of such clauses or pursuant to the
first paragraph hereof. Accrual of interest, accretion or amortization of
original issue discount, the payment of interest on any Indebtedness in the form
of additional Indebtedness with the same terms, and the payment of dividends on
preferred stock in the form of additional shares of the same class of preferred
stock will not be deemed to be an incurrence of Indebtedness or an issuance of
preferred stock for purposes of this covenant; PROVIDED, in each such case, that
the amount thereof is included in Consolidated Indebtedness of the Company as
accrued.
 
                                       56

any of its Restricted Subsidiaries to, enter into any sale and leaseback
transaction; PROVIDED that the Company or a Restricted Subsidiary of the Company
may enter into a sale and leaseback transaction if (i) the Company could have
(a) incurred Indebtedness in an amount equal to the Attributable Debt relating
to such sale and leaseback transaction pursuant to the Debt to Cash Flow test
set forth in the first paragraph of the covenant described above under the
caption "--Incurrence of Additional Indebtedness and Issuance of Preferred
Stock" and (b) incurred a Lien to secure such Indebtedness pursuant to the
covenant described below under the caption "--Liens," (ii) the gross cash
proceeds of such sale and leaseback transaction are at least equal to the fair
market value (as determined in good faith by the Board of Directors and set
forth in an Officers' Certificate delivered to the Trustee) of the property that
is the subject of such sale and leaseback transaction and (iii) the transfer of

Liens.
 
    DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES
 
    The Indenture will provide that the Company will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly, create or
otherwise cause or suffer to exist or become effective any encumbrance or
restriction on the ability of any Restricted Subsidiary to (i)(a) pay dividends
or make any other distributions to the Company or any of its Restricted

such are in effect on the date of the Indenture, (c) the Six Flags Credit
Facility as in effect as of the date of the Indenture, and any amendments,
modifications, restatements, renewals, increases, supplements, refundings,
replacements or refinancings thereof, PROVIDED that such amendments,
modifications, restatements, renewals, increases, supplements, refundings,
replacements or refinancings are no more restrictive, taken as a whole, with
respect to such dividend and other payment restrictions than those contained in
the Six Flags Credit Facility as in effect on the date of the Indenture, (d) the
Indenture and the Notes, (e) applicable law, (f) any instrument governing
Indebtedness or Capital Stock of a Person acquired by the Company or any of its
Restricted Subsidiaries as in effect at the time of such acquisition (except to
the extent such Indebtedness was incurred in connection with or in contemplation
of such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person, or the
property or assets of the Person, so acquired, PROVIDED that, in the case of

be incurred, (g) customary non-assignment provisions in leases entered into in

Indebtedness, (k) provisions with
 
                                       57
<PAGE>
respect to the disposition or distribution of assets or property in joint
venture agreements and other similar agreements entered into in the ordinary
course of business and (l) restrictions on cash or other deposits or net worth
imposed by customers under contracts entered into in the ordinary course of
business.
 
    MERGER, CONSOLIDATION, OR SALE OF ASSETS
 
    The Indenture will provide that the Company may not consolidate or merge
with or into (whether or not the Company is the surviving corporation), or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially all
of its properties or assets in one or more related transactions, to another
corporation, Person or entity unless (i) the Company is the surviving

the entity or Person to which such sale, assignment, transfer, lease, conveyance
or other disposition shall have been made assumes all the obligations of the
Company under the Notes, the Indenture and the Pledge and Escrow Agreement
pursuant to a supplemental Indenture in form reasonably satisfactory to the
Trustee; (iii) immediately after such transaction no Default or Event of Default
exists; and (iv) except in the case of a merger of the Company with or into a
Wholly Owned Restricted Subsidiary of the Company, the Company or the entity or
Person formed by or surviving any such consolidation or merger (if other than
the Company), or to which such sale, assignment, transfer, lease, conveyance or
other disposition shall have been made (A) will have Consolidated Net Worth
immediately after the transaction equal to or greater than the Consolidated Net
Worth of the Company immediately preceding the transaction and (B) will, both at
the time of such transaction and after giving pro forma effect thereto as if
such transaction had occurred at the beginning of the applicable four-quarter
period, be permitted to incur at least $1.00 of additional Indebtedness pursuant
to the Debt to Cash Flow test set forth in the first paragraph of the covenant
described above under the caption "--Incurrence of Indebtedness and Issuance of
Preferred Stock."
 
    TRANSACTIONS WITH AFFILIATES
 
    The Indenture will provide that the Company will not, and will not permit
any of its Restricted Subsidiaries to, make any payment to, or sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or purchase
any property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"),
unless (i) such Affiliate Transaction is on terms that are no less favorable to
the Company or the relevant Restricted Subsidiary than those that would have
been obtained in a comparable transaction by the Company or such Restricted
Subsidiary with an unrelated Person and (ii) the Company delivers to the Trustee
(a) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $   million, a
resolution of the Board of Directors set forth in an Officers' Certificate
certifying that such Affiliate Transaction complies with clause (i) above and
that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors and (b) with respect to any
Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $    million, an opinion as to the fairness
to the Holders of such Affiliate Transaction from a financial point of view
issued by an accounting, appraisal or investment banking firm of national
standing. Notwithstanding the foregoing, the following items shall not be deemed
to be Affiliate Transactions: (i) any employment agreement entered into by the
Company or any of its Restricted Subsidiaries in the ordinary course of
business, or any issuance of securities, or other payments, awards or grants in
cash, securities or otherwise pursuant to, or the funding of, employment or

Agreements as the same are in effect on the date of the Indenture.
 
    LIMITATION ON ISSUANCES AND SALES OF EQUITY INTERESTS IN RESTRICTED
     SUBSIDIARIES
 
    The Indenture will provide that the Company (i) will not, and will not
permit any Restricted Subsidiary of the Company to, transfer, convey, sell,
lease or otherwise dispose of any Equity Interests in any Restricted Subsidiary
of the Company to any Person (other than the Company or a Restricted Subsidiary
of the Company), unless (a)(1) such transfer, conveyance, sale, lease or other
disposition is of all the Equity Interests in such Restricted Subsidiary or (2)
after giving effect thereto, such Restricted Subsidiary will still constitute a
Restricted Subsidiary and (b) the cash Net Proceeds from such transfer,
conveyance, sale, lease or other disposition are applied in accordance with the
covenant described above under the caption "--Repurchase at the Option of
Holders--Asset Sales," and (ii) will not permit any Restricted Subsidiary of the
Company to issue any of its Equity Interests (other than, if necessary, shares
of its Capital Stock constituting directors' qualifying shares) to any Person
other than to the Company or a Wholly Owned Restricted Subsidiary of the
Company.
 
    BUSINESS ACTIVITIES
 
    The Indenture will provide that the Company will not, and will not permit
any Restricted Subsidiary to, engage in any business other than Permitted
Businesses, except to such extent as would not be material to the Company and
its Restricted Subsidiaries taken as a whole.
 
    PAYMENTS FOR CONSENT
 
    The Indenture will provide that neither the Company nor any of its
Subsidiaries will, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any Holder of
any Notes for or as an inducement to any consent, waiver or amendment of any of
the terms or provisions of the Indenture or the Notes unless such consideration
is offered to be paid or is paid to all Holders of the Notes that consent, waive
or agree to amend in the time frame set forth in the solicitation documents
relating to such consent, waiver or agreement.
 
    REPORTS
 
    The Indenture will provide that, whether or not required by the rules and
regulations of the Securities and Exchange Commission (the "Commission"), so
long as any Notes are outstanding, the Company will furnish to the Holders of
Notes (i) all quarterly and annual financial information that would be required
to be contained in a filing with the Commission on Forms 10-Q and 10-K if the
Company were required to file such Forms, including a "Management's Discussion
and Analysis of Financial Condition and Results of Operations" that describes
the financial condition and results of operations of the Company and its
consolidated Subsidiaries (showing in reasonable detail, either on the face of
the financial statements or in the footnotes thereto and in Management's
Discussion and Analysis of Financial Condition and Results of Operations, the
financial condition and results of operations of the Company and its Restricted
Subsidiaries separate from the financial condition and results of operations of
the Unrestricted Subsidiaries of the Company) and, with respect to the annual
information only, a report thereon by the Company's certified
 
                                       59
<PAGE>
independent accountants and (ii) all current reports that would be required to
be filed with the Commis-
sion on Form 8-K if the Company were required to file such reports, in each case
within the time periods specified in the Commission's rules and regulations. In
addition, whether or not required by the rules and regulations of the
Commission, the Company will file a copy of all such information and reports
with the Commission for public availability within the time periods specified in
the Commission's rules and regulations (unless the Commission will not accept
such a filing) and make such information available to securities analysts and
prospective investors upon request.
 
EVENTS OF DEFAULT AND REMEDIES
 
    The Indenture will provide that each of the following constitutes an Event
of Default with respect to the Notes: (i) default for 30 days in the payment
when due of interest on the Notes; (ii) default in payment when due of the
principal of or premium, if any, on the Notes; (iii) failure by the Company to
comply for 30 days with the provisions described under the captions "--Escrow of
Proceeds," "--Repurchase at the Option of Holders" and "--Certain Covenants" (in
each case, other than a failure to purchase Notes); (iv) failure by the Company
for 60 days after notice to comply with any of the Company's other agreements in
the Indenture, the Pledge and Escrow Agreement or the Notes; (v) the failure by
the Company or any Restricted Subsidiary to pay Indebtedness within any
applicable grace period after final maturity or the acceleration of any
Indebtedness by the holders thereof because of a default and the total amount of
such Indebtedness unpaid or accelerated exceeds $   million; (vi) failure by the
Company or any of its Restricted Subsidiaries to pay final judgments aggregating
in excess of $    million, which judgments are not paid, discharged or stayed
for a period of 60 days; and (vii) certain events of bankruptcy or insolvency
with respect to the Company, any Restricted Subsidiary that constitutes a
Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together, would constitute a Significant Subsidiary.
 
    If any Event of Default occurs and is continuing, either Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, with respect to the Company, any Restricted Subsidiary
of the Company that constitutes a Significant Subsidiary or any group of
Restricted Subsidiaries of the Company that, taken together, would constitute a
Significant Subsidiary, all outstanding Notes will become due and payable
without further action or notice. Holders of the Notes may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest.
 
    In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. If an Event of Default occurs prior to
      , 2003 by reason of any willful action (or inaction) taken (or not taken)
by or on behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to       , 2003, then the premium specified in the
Indenture shall also become immediately due and payable to the extent permitted
by law upon the acceleration of the Notes.
 
    The Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes of such series waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default
in the payment of interest on, or the principal of, the Notes.
 
                                       60
<PAGE>
    The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS
 
    No director, officer, employee, incorporator or stockholder of the Company,
as such, shall have any liability for any obligations of the Company under the
Notes, the Indenture or for any claim based on, in respect of, or by reason of,
such obligations or their creation. Each Holder of Notes by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. Such waiver may not be effective to
waive liabilities under the federal securities laws and it is the view of the
Commission that such a waiver is against public policy.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
    The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Notes ("Legal
Defeasance"), except for (i) the rights of Holders of outstanding Notes to
receive payments in respect of the principal of, premium, if any, and interest
on such Notes when such payments are due from the trust referred to below, (ii)
the Company's obligations with respect to the Notes concerning issuing temporary
Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the
maintenance of an office or agency for payment and money for security payments
held in trust, (iii) the rights, powers, trusts, duties and immunities of the
Trustee, and the Company's obligations in connection therewith and (iv) the
Legal Defeasance provisions of the Indenture. In addition, the Company may, at
its option and at any time, elect to have the obligations of the Company
released with respect to certain covenants that are described in the Indenture
("Covenant Defeasance") and thereafter any omission to comply with such
obligations shall not constitute a Default or Event of Default with respect to
the Notes. In the event Covenant Defeasance occurs, certain events (not
including non-payment, bankruptcy, receivership, rehabilitation and insolvency
events) described under "Events of Default" will no longer constitute an Event
of Default with respect to the Notes.
 
    In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders of the Notes, cash in U.S. dollars, non-callable Government
Securities, or a combination thereof, in such amounts as will be sufficient, in
the opinion of a nationally recognized firm of independent public accountants,
to pay the principal of, premium, if any, and interest on the outstanding Notes
on the stated maturity or on the applicable redemption date, as the case may be,
and the Company must specify whether the Notes are being defeased to maturity or
to a particular redemption date; (ii) in the case of Legal Defeasance, the

consent of the Holders of at least a majority in principal amount of the Notes
then outstanding (including, without limitation, consents obtained in connection
with a purchase of, or tender offer or exchange offer for such Notes), and any
existing default or compliance with any provision of the Indenture, the Notes or
the Pledge and Escrow Agreement may be waived with the consent of the Holders of
a majority in principal amount of the then outstanding Notes (including, without
limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for, Notes).
 
    Without the consent of each Holder affected, an amendment or waiver may not

                                       62
<PAGE>
    Notwithstanding the foregoing, without the consent of any Holder of Notes,
the Company and the Trustee may amend or supplement the Indenture, the Notes or
the Pledge and Escrow Agreement to cure any ambiguity, defect or inconsistency,
to provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of the Company's obligations to Holders of
Notes in the case of a merger or consolidation or sale of all or substantially
all of the Company's assets, to make any change that would provide any
additional rights or benefits to the Holders of Notes or that does not adversely
affect the legal rights under the Indenture of any such Holder, or to comply
with requirements of the Commission in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act.
 
CONCERNING THE TRUSTEE
 
    The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the Commission for permission to continue
or resign.
 
    The Holders of a majority in principal amount of the then outstanding Notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur (which shall not be cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the conduct
of his own affairs. Subject to such provisions, the Trustee will not be under an
obligation to exercise any of its rights or powers under the Indenture at the
request of any Holder of Notes, unless such Holder shall have offered to the
Trustee security and indemnity satisfactory to it against any loss, liability or
expense.
 
ADDITIONAL INFORMATION
 
    Anyone who receives this Prospectus may obtain a copy of the Indenture
without charge by writing to Six Flags Entertainment Corporation, 11501
Northeast Expressway, Oklahoma City, Oklahoma 73131, Attention: Chief Financial
Officer.
 
BOOK-ENTRY, DELIVERY AND FORM
 
    Except as set forth in the next paragraph, the Notes to be resold as set
forth herein will initially be issued in the form of one or more Global Notes
(the "Global Notes"). The Global Notes will be deposited on the date of the
closing of the sale of the Notes offered hereby (the "Closing Date") with, or on
behalf of, The Depository Trust Company (the "Depositary") and registered in the
name of Cede & Co., as nominee of the Depositary (such nominee being referred to
herein as the "Global Note Holder").
 
    Notes that are issued as described below under "--Certificated Securities"
will be issued in the form of registered definitive certificates (the
"Certificated Securities"). Upon the transfer of Certificated Securities, such
Certificated Securities may, unless all Global Notes have previously been
exchanged for Certificated Securities, be exchanged for an interest in the
Global Note representing the principal amount of Notes being transferred,
subject to the transfer restrictions set forth in the Indenture.
 
    The Depositary is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the "Participants"
or the "Depositary's Participants") and to facilitate the clearance and
settlement of transactions in such securities between Participants through
electronic book-entry changes in accounts of its Participants. The Depositary's
Participants include securities brokers and dealers (including the
Underwriters), banks and trust companies, clearing corporations and certain
other organizations. Access to the Depositary's system is also available to
other entities such as banks, brokers, dealers and trust companies
(collectively, the "Indirect Participants" or the "Depositary's Indirect
Participants") that clear through or maintain a custodial relationship with a
 
                                       63
<PAGE>
Participant, either directly or indirectly. Persons who are not Participants may
beneficially own securities held by or on behalf of the Depositary only thorough
the Depositary's Participants or the Depositary's Indirect Participants.
 
    The Company expects that pursuant to procedures established by the
Depositary (i) upon deposit of the Global Notes, the Depositary will credit the
accounts of Participants designated by the Underwriters with portions of the
principal amount of the Global Notes and (ii) ownership of the Notes evidenced
by the Global Notes will be shown on, and the transfer of ownership thereof will
be effected only through, records maintained by the Depositary (with respect to
the interests of the Depositary's Participants), the Depositary's Participants
and the Depositary's Indirect Participants. Prospective purchasers are advised
that the laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer Notes evidenced by the Global Note will be limited to such extent. For
certain other restrictions on the transferability of the Notes, see "Notice to
Investors."
 
    So long as the Global Note Holder is the registered owner of any Notes, the
Global Note Holder will be considered the sole Holder under the Indenture of any
Notes evidenced by the Global Notes. Beneficial owners of Notes evidenced by the
Global Notes will not be considered the owners or Holders thereof under the
Indenture for any purpose, including with respect to the giving of any
directions, instructions or approvals to the Trustee thereunder. Neither the
Company nor the Trustee will have any responsibility or liability for any aspect
of the records of the Depositary or for maintaining, supervising or reviewing
any records of the Depositary relating to the Notes.
 
    Payments in respect of the principal of, premium, if any, interest on any
Notes registered in the name of the Global Note Holder on the applicable record
date will be payable by the Trustee to or at the direction of the Global Note
Holder in its capacity as the registered Holder under the Indenture. Under the
terms of the Indenture, the Company and the Trustee may treat the persons in
whose names Notes, including the Global Notes, are registered as the owners
thereof for the purpose of receiving such payments. Consequently, neither the
Company nor any Trustee has or will have any responsibility or liability for the
payment of such amounts to beneficial owners of Notes. The Company believes,
however, that it is currently the policy of the Depositary to immediately credit
the accounts of the relevant Participants with such payments, in amounts
proportionate to their respective holdings of beneficial interests in the
relevant security as shown on the records of the Depositary. Payments by the
Depositary's Participants and the Depositary's Indirect Participants to the
beneficial owners of Notes will be governed by standing instructions and
customary practice and will be the responsibility of the Depositary's
Participants or the Depositary's Indirect Participants.
 
    CERTIFICATED SECURITIES
 
    Subject to certain conditions, any person having a beneficial interest in a
Global Note may, upon request to the Trustee, exchange such beneficial interest
for Notes in the form of Certificated Securities. Upon any such issuance, the
Trustee is required to register such Certificated Securities in the name of, and
cause the same to be delivered to, such person or persons (or the nominee of any
thereof). All such certificated Notes would be subject to the legend
requirements described herein under "Notice to Investors." In addition, if (i)
the Company notifies the Trustee in writing that the Depositary is no longer
willing or able to act as a depositary and the Company is unable to locate a
qualified successor within 90 days or (ii) the Company, at its option, notifies
the Trustee in writing that it elects to cause the issuance of Notes in the form
of Certificated Securities under the Indenture, then, upon surrender by the
Global Note Holder of its Global Note, Notes in such form will be issued to each
person that the Global Note Holder and the Depositary identify as being the
beneficial owner of the related Notes.
 
    Neither the Company nor the Trustee will be liable for any delay by the
Global Note Holder or the Depositary in identifying the beneficial owners of
Notes and the Company and the Trustee may conclusively rely on, and will be
protected in relying on, instructions from the Global Note Holder or the
Depositary for all purposes.
 
                                       64
<PAGE>
    SAME DAY SETTLEMENT AND PAYMENT
 
    The Indenture will require that payments in respect of the Notes represented
by the Global Note (including principal, premium, if any, interest , if any) be
made by wire transfer of immediately available next day funds to the accounts
specified by the Global Note Holder. With respect to Certificated Securities,
the Company will make all payments of principal, premium, if any, interest , if
any, by wire transfer of immediately available funds to the accounts specified
by the Holders thereof or, if no such account is specified, by mailing a check
to each such Holder's registered address. The Company expects that secondary
trading in the Certificated Securities will also be settled in immediately
available funds.

                      DESCRIPTION OF PREMIER CAPITAL STOCK
 
COMMON STOCK
 
    Premier's authorized capital stock includes 90,000,000 shares of Common
Stock, par value $0.05 per share. Each share of Common Stock entitles the holder
thereof to one vote. Holders of the Common Stock have equal ratable rights to
dividends from funds legally available therefor, when, as and if declared by the
Board of Directors and are entitled to share ratably, as a single class, in all
of the assets of Premier available for distribution to holders of Common Stock
upon the liquidation, dissolution or winding up of the affairs of Premier.
Holders of Common Stock do not have preemptive, subscription or conversion
rights. However, each outstanding share of Common Stock currently has attached
to it one right (a "Right") issued pursuant to a Rights Agreement (the "Rights
Agreement"). Each Right entitles its registered holder to purchase one
one-hundredth of a share of a junior participating series of Preferred Stock
designated to have economic and voting terms similar to those of one share of
Common Stock. After the Offerings,     shares of Common Stock will be
outstanding and       shares will be reserved for future issuance (      for
options and warrants and       upon conversion of the Convertible Preferred
Stock).
 
    Bank One Trust Company, N.A., Oklahoma City, Oklahoma, is the transfer agent
and registrar for the Common Stock.
 
PREFERRED STOCK
 
    Premier's authorized capital stock includes 500,000 shares of Preferred
Stock, par value $1.00 per share. The Preferred Stock may be issued in series,
and shares of each series will have such rights and preferences as are fixed by
the Board of Directors in resolutions authorizing the issuance of that
particular series. In designating any series of Preferred Stock, the Board of
Directors may, without further action by the holders of Common Stock, fix the
number of shares constituting that series and fix the dividend rights, dividend
rate, conversion rights, voting rights (which may be greater or lesser than the
voting rights of the Common Stock), rights and terms of redemption (including
any sinking fund provisions), and the liquidation preferences of such series of
Preferred Stock. Holders of any series of Preferred Stock, when and if issued,
may have priority claims to dividends and to any distributions upon liquidation
of Premier, and other preferences over the holders of the Common Stock. After
giving effect to the Six Flags Transactions,       shares of Preferred Stock
will be outstanding. In addition, approximately 206,000 shares (which will be
amended to 20,600 prior to the date of this Prospectus) of Preferred Stock have
been reserved for issuance under the Rights Plan.
 
    MANDATORILY CONVERTIBLE PREFERRED STOCK
 
    Pursuant to the Preferred Stock Offering, Premier will issue Public
Depositary Shares in respect of its Mandatorily Convertible Preferred Stock.
 
    DIVIDENDS.  Subject to the terms of the New Premier Notes, holders of the
shares of Mandatorily Convertible Preferred Stock will be entitled to receive,
when, as and if declared by the Board of Directors out of funds legally
available therefor, cash dividends from the date of initial issuance of the
shares of Mandatorily Convertible Preferred Stock at the rate of $         per
annum or $         per quarter. Dividends will cease to accrue on the shares of
Mandatorily Convertible Preferred Stock on the Mandatory Conversion Date or on
the date of their earlier conversion at the option of the holder.
 
    Dividends may be paid, at the election of Premier, (i) out of funds legally
available therefor, (ii) through the delivery of shares of Common Stock or (iii)
through any combination of the foregoing forms of consideration elected by the
Board of Directors in its sole discretion.
 
                                       79
<PAGE>
    The shares of Mandatorily Convertible Preferred Stock will rank on a parity,
both as to payment of dividends and distribution of assets upon liquidation,
with the Seller Preferred Stock and any other preferred stock issued in the
future by Premier that by its terms ranks PARI PASSU with the shares of
Mandatorily Convertible Preferred Stock.
 
    MANDATORY CONVERSION OF MANDATORILY CONVERTIBLE PREFERRED STOCK.  Unless
voluntarily converted into Common Stock, as hereinafter described, on
          , 2001 (the "Mandatory Conversion Date") each share of Mandatorily
Convertible Preferred Stock will automatically convert into a number of shares
of Common Stock (or the equivalent amount of cash) at the Conversion Rate (as
defined below). The "Conversion Rate" is equal to, (a) if the Conversion Price
(as defined below) is greater than or equal to $         (the "Threshold
Appreciation Price"),    shares of Common Stock per Mandatorily Convertible
Preferred Stock (equivalent to       shares of Common Stock for each Depositary
Share), (b) if the Conversion Price is less than the Threshold Appreciation
Price but is greater than $         (the "Initial Price"), a fraction, equal to
the Initial Price divided by the Conversion Price, of five hundred shares of
Common Stock per Mandatorily Convertible Preferred Stock (equivalent to 1/500th
of such number of shares for each Public Depositary Share) and (c) if the
Conversion Price is less than or equal to the Initial Price, 500 shares of
Common Stock per Mandatorily Convertible Preferred Stock (equivalent to one
share of Common Stock for each Public Depositary Share). The Conversion Rate is
subject to adjustment in certain circumstances, including if Premier shall (a)
pay a stock dividend or make a distribution with respect to its Common Stock in
shares of Common Stock, (b) subdivide or split its outstanding Common Stock, (c)
combine its outstanding Common Stock into a smaller number of shares, (d) issue
by reclassification of its shares of Common Stock any shares of Common Stock,
(e) issue certain rights or warrants to all holders of its Common Stock unless
such rights or warrants are issued to each holder of shares of Mandatorily
Convertible Preferred Stock on a pro rata basis with the shares of Common Stock
based on the Conversion Rate in effect on the date immediately preceding such
issuance, or (f) pay certain dividends or distribute to all holders of its
Common Stock evidences of its indebtedness, cash or other assets unless such
dividend or distribution is made to each holder of shares of Mandatorily
Convertible Preferred Stock on a pro rata basis with the shares of Common Stock
based on the Conversion Rate in effect on the date immediately preceding such
dividend or distribution.
 
    The "Conversion Price" is the average closing price per share of Common
Stock for the 20 trading days immediately prior to (but not including) the
Mandatory Conversion Date; provided, however, that if there are not 20 trading
days for the Common Stock occurring later than the 60th calendar day immediately
prior to, but not including, the Mandatory Conversion Date, "Conversion Price"
will be the market value per share of Common Stock as of the Mandatory
Conversion Date as determined by a nationally recognized investment banking firm
retained for such purpose by Premier. The Conversion Price is subject to
adjustment in certain circumstances.
 
    Premier will have the option, exercisable in its sole discretion, to satisfy
its obligations pursuant to the mandatory conversion of the Mandatorily
Convertible Preferred Stock at the Mandatory Conversion Date by delivering to
holders of the Mandatorily Convertible Preferred Stock either the number of
shares of Common Stock specified above or cash in an amount equal to the product
of such number of shares multiplied by the Conversion Price.
 
    CONVERSION AT THE OPTION OF THE HOLDER.  The shares of Mandatorily
Convertible Preferred Stock (and thereby the Public Depositary Shares) are
convertible, in whole or in part, at the option of the holders thereof, at any
time prior to the Mandatory Conversion Date, into shares of Common Stock at a
rate of     shares of Common Stock for each share of Mandatorily Convertible
Preferred Stock (or a rate of     shares of Common Stock for each Public
Depositary Share) equivalent, for each Depositary Share, to a conversion price
of $         per share of Common Stock, subject to adjustment in certain
circumstances, including if Premier shall (a) pay a stock dividend or make a
distribution with respect to its Common Stock in shares of Common Stock, (b)
subdivide or split its outstanding Common Stock, (c) combine its outstanding
Common Stock into a smaller number of shares, (d) issue by reclassification of
 
                                       80
<PAGE>
its shares of Common Stock any shares of Common Stock, (e) issue certain rights
or warrants to all holders of its Common Stock unless such rights or warrants
are issued to each holder of shares of Mandatorily Convertible Preferred Stock
on a pro rata basis with the shares of Common Stock based on the Conversion Rate
in effect on the date immediately preceding such issuance, or (f) pay certain
dividends or distribute to all holders of its Common Stock evidences of its
indebtedness, cash or other assets unless such dividend or distribution is made
to each holder of shares of Mandatorily Convertible Preferred Stock on a pro
rata basis with the shares of Common Stock based on the Conversion Rate in
effect on the date immediately preceding such dividend or distribution.
 
    The depositary shares representing shares of Mandatorily Convertible
Preferred Stock may be voluntarily converted by the holders thereof upon the
same terms and conditions as the shares of Mandatorily Convertible Preferred
Stock represented by such depositary shares, adjusted to reflect the fact that
depositary shares represent a one-five hundredth interest of a share of
Mandatorily Convertible Preferred Stock.
 
    LIQUIDATION RIGHTS.  In the event of any voluntary or involuntary
liquidation, dissolution, or winding up of Premier, and subject to the rights of
holders of any other series of Preferred Stock, the holders of outstanding
shares of Mandatorily Convertible Preferred Stock are entitled to receive an
amount equal to the per share price to investors of the shares of Mandatorily
Convertible Preferred Stock plus accrued and unpaid dividends thereon, out of
the assets of Premier available for distribution to stockholders, before any
distribution of assets is made to holders of junior ranking stock upon
liquidation, dissolution or winding up.
 
    VOTING RIGHTS.  The holders of shares of Mandatorily Convertible Preferred
Stock shall not be entitled to any voting rights, except as required by
applicable state law and as described below.
 
    In the event that dividends on the shares of Mandatorily Convertible
Preferred Stock or any other series of Preferred Stock shall be in arrears and
unpaid for six quarterly dividend periods, or if any other series of Preferred
Stock shall be entitled for any other reason to exercise voting rights, separate
from the Common Stock, to elect any Directors of Premier ("Preferred Stock
Directors"), the holders of the shares of Mandatorily Convertible Preferred
Stock, will be entitled to vote for the election of two Preferred Stock
Directors, such Directors to be in addition to the number of Directors
constituting the Board of Directors immediately prior to the accrual of such
right.
 
    Premier will not, without the approval of the holders of at least 66 2/3
percent of all the shares of Mandatorily Convertible Preferred Stock then
outstanding: (i) amend, alter, or repeal any of the provisions of the
Certificate of Incorporation or the By-laws of the Company so as to affect
adversely the powers, preferences, or rights of the holders of the shares of
Mandatorily Convertible Preferred Stock then outstanding or reduce the minimum
time required for any notice to which only the holders of the shares of
Mandatorily Convertible Preferred Stock then outstanding may be entitled; (ii)
create any series of preferred stock ranking prior to the shares of Mandatorily
Convertible Preferred Stock as to payment of dividends or the distribution of
assets upon liquidation; or (iii) authorize or create, or increase the
authorized amount of, any capital stock, or any security convertible into
capital stock, of any class ranking prior to the shares of Mandatorily
Convertible Preferred Stock as to payment of dividends or the distribution of
assets upon liquidation.
 
    Holders of shares of Mandatorily Convertible Preferred Stock have no
preemptive rights.
 
    SELLER PREFERRED STOCK
 
    In connection with the Six Flags Acquisition, Premier will issue to the
Sellers up to       Seller Depositary Shares for up to $200 million of Seller
Preferred Stock. The Company has the right to pay cash in lieu of all or a
portion of such shares, provided that if any Seller Depositary Shares are issued
to the
 
                                       81
<PAGE>
Sellers not less than   shares (representing not less than $100 million of the
Capital Stock Consideration must be issued). The following is a summary of the
terms of the Seller Preferred Stock.
 
    DIVIDENDS.  Subject to the terms of the New Premier Notes, holders of shares
of the Seller Preferred Stock will be entitled to receive annually, cash
dividends out of funds of the Company legally available for payment, at an
annual rate of    % of the $         liquidation value (the "Liquidation Value")
per share. Dividends will be cumulative from the date of original issuance of
the Seller Preferred Stock. The Seller Preferred Stock will rank PARI PASSU as
to dividends with the Mandatorily Convertible Preferred Stock and have priority
as to dividends over the Common Stock and any other series or class of Premier's
stock hereafter issued.
 
    LIQUIDATION RIGHTS.  In case of the voluntary or involuntary liquidation,
dissolution or winding up of Premier, holders of shares of Seller Preferred
Stock are entitled to receive the amount equal to the Liquidation Value thereof,
plus an amount equal to any accrued and unpaid dividends to the payment date,
before any payment or distribution is made to the holders of Common Stock or any
other series or class of Premier's stock hereafter issued which ranks junior as
to liquidations rights to the Seller Preferred Stock. The Seller Preferred Stock
will rank PARI PASSU as to liquidation with the Mandatorily Convertible
Preferred Stock.

at the option of the holder into shares of Common Stock at a conversion price of
$         per share of Common Stock, subject to adjustment as described below.
The holders of Seller Preferred Stock will be entitled at any time after the

distributions of evidences of indebtedness or assets to holders of certain of
Premier's capital stock.

make a market in the SFEC Senior Notes. However, the Underwriters are not
obligated to do so. Any market making activities with respect to the Company
Notes may be discontinued at any time without notice. In addition, such
market-making activity will be subject to the limits imposed by the Securities
Act and the Exchange Act. See "Risk Factors--Absence of Public Market."
 
    In connection with the Offering, the Underwriters may engage in certain
transactions that stabilize the price of the SFEC Senior Notes. Such
transactions may consist of bids or purchases for the purpose of pegging, fixing
or maintaining the price of the SFEC Senior Notes. If the Underwriters create a
short position in the SFEC Senior Notes in connection with the Offering (i.e.,
if they sell more SFEC Senior Notes than are set forth on the cover page of this
Prospectus) the Underwriters may reduce that short position by purchasing SFEC
Senior Notes in open market.
 
    In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might otherwise be in the absence of such purchases.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Six Flags Entertainment Corporation
 
    We have audited the accompanying consolidated balance sheets of Six Flags
Entertainment Corporation as of December 28, 1997 and December 29, 1996 and the
related consolidated statements of operations, stockholders' equity (deficit)
and cash flows for each of the three years in the period ended December 28,
1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Six Flags Entertainment Corporation at December 28, 1997 and December 29, 1996
and the consolidated results of its operations and its cash flows for each of
the three years in the period ended December 28, 1997 in conformity with
generally accepted accounting principles.

                      SIX FLAGS ENTERTAINMENT CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
BASIS OF PRESENTATION
 
    Six Flags Entertainment Corporation ("SFEC", and together with its
subsidiaries, the "Company"), a Delaware corporation, was formed in 1991 to
effect the acquisition of S.F. Holdings, Inc. ("Holdings") and its subsidiary
Six Flags Theme Parks Inc. ("Six Flags"). The Company owns 100% of the Common
Stock of Holdings, which owns 100% of the Common Stock of Six Flags. Prior to
June 23, 1995, the Company was wholly owned by Time Warner Entertainment
Company, L.P., a Delaware limited partnership ("TWE"). On June 23, 1995, TWE
caused the Company to undergo a recapitalization and TWE sold 51% of its
interest in the Company to an investor group (the "Investor Group") led by
Boston Ventures Management, Inc., a private investment management firm (the
"1995 Recapitalization"). In connection with the 1995 Recapitalization, the
Company consummated a series of transactions (the "1995 Refinancing", together
with the 1995 Recapitalization, the "1995 Refinancing and Recapitalization").
 
    SFEC and Holdings are holding companies which have no significant operations
independent of their ownership of Six Flags. Accordingly, the consolidated
financial statements of the Company consist principally of the assets,
liabilities, operations and cash flows of Six Flags. All significant
intercompany accounts and transactions have been eliminated. Certain amounts
have been reclassified to conform to the current year presentation.
 
    Six Flags operates twelve "Six Flags" branded theme parks in eight locations
throughout the United States. Nine of the theme parks--Six Flags Great Adventure
and Wild Safari Animal Park (New York-Philadelphia), Six Flags Great America
(Chicago-Milwaukee), Six Flags Magic Mountain and Six Flags Hurricane Harbor
(Los Angeles) (collectively "Six Flags California"), Six Flags Astroworld and
Six Flags Waterworld (Houston) (collectively "Six Flags Houston"), Six Flags St.
Louis (St. Louis) and Six Flags Hurricane Harbor (Dallas-Ft. Worth)--are owned
directly by Six Flags. Six Flags Fiesta Texas located in San Antonio, Texas is
leased by a limited partnership of which a subsidiary of Six Flags is a general
partner and manages the park. Two parks--Six Flags Over Texas (Dallas-Ft. Worth)
and Six Flags Over Georgia (Atlanta)--are operated by Six Flags pursuant to
partnership agreements (the "co-venture parks"). Six Flags Over Texas is owned
by a limited partnership ("Texas Flags") of which the managing general partner
is a wholly-owned subsidiary of Six Flags. Six Flags Over Georgia is owned by a
limited partnership of which the managing general partner is SFOG II, Inc., a
Delaware corporation which is a wholly-owned subsidiary of SFEC ("SFOG II"). The
Company has entered into new partnership agreements for the management of Six
Flags Over Georgia and Six Flags Over Texas through 2026 and 2027, respectively.
See the Investment In Co-venture Parks footnote for a description of these new
agreements.
 
    In March 1996, Six Flags completed arrangements pursuant to which Six Flags,
through wholly-owned subsidiaries, manages the Fiesta Texas theme park located
in San Antonio, Texas ("Fiesta Park"). The Fiesta Park, which is owned by a
subsidiary of La Cantera Development Company ("La Cantera"), an affiliate of
United Service Automobile Association ("USAA"), was leased to a newly formed
limited partnership (the "Fiesta Partnership") in which Six Flags, acting
through wholly-owned subsidiaries (the "Six Flags GP"), is a general partner
with an approximate 60% equity interest. La Cantera is the limited partner with
a 40% equity interest. In connection with these arrangements, the Fiesta
Partnership obtained an option to purchase the tangible and intangible assets
related to the Fiesta Park as well as the limited partner's interest in the
Fiesta Partnership. In addition, Six Flags GP receives an annual management fee
and intellectual property fee in connection with the management of the Fiesta
Park. The management fee is based on revenues for 1996 and 1997 and will be
based on operating profit thereafter. The intellectual property fee is based on
revenues.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
    Six Flags' consolidated results for 1996 include a full year of Fiesta
Park's operations. The following unaudited proforma financial information for
the 1995 fiscal year gives effect to consolidation of Fiesta Park as if it had
occurred at the beginning of the 1995 fiscal year. These proforma results are
not necessarily indicative of what the results would have been had Six Flags
actually managed the park during 1995. Proforma revenues and net loss would have
been $672 million and $8.6 million, respectively, if the consolidation of the
Fiesta Park occurred at the beginning of the 1995 fiscal year.
 
    The 1997, 1996, and 1995 fiscal years each consisted of 52 weeks. The 1997
fiscal year ended on December 28, 1997, while the 1996 and 1995 fiscal years
ended on December 29, 1996 and December 31, 1995, respectively.
 
1995 REFINANCING AND RECAPITALIZATION
 
    The 1995 Refinancing and Recapitalization was effected through the following
transactions consummated in June 1995:
 
    1.  SFEC effected a recapitalization (the "Recapitalization") pursuant to
       which its Common Stock (all of which was owned by TWE) was recapitalized
       into shares of Class A Convertible Preferred Stock (representing
       approximately 51% of the equity), Class B Convertible Preferred Stock
       (representing approximately 49% of the equity) and Common Stock (the
       "SFEC Common Stock"), which has nominal value.
 
    2.  TWE sold to the Investor Group all of the outstanding shares of SFEC's
       Class A Convertible Preferred Stock and 51% of the outstanding shares of
       the SFEC Common Stock.
 
    3.  Six Flags borrowed $475.0 million on a term basis pursuant to a credit
       agreement dated as of June 23, 1995 (the "Credit Agreement") with a group
       of banks.
 
    4.  Six Flags issued $285.0 million aggregate principal amount of 12.25%
       Senior Subordinated Discount Notes due 2005 (the "12.25% Notes") at an
       aggregate issue price of $200.0 million.
 
    5.  Six Flags paid TWE $640 million in connection with (i) the repurchase of
       all assets previously sold to TWE as part of the sale and leaseback
       transactions, (ii) the repayment of intercompany indebtedness and related
       accrued interest, (iii) a payment as required under a license agreement
       entered into with TWE and (iv) a payment in consideration of TWE entering
       into a non-competition agreement for the benefit of the Company. The
       total amount paid to TWE in excess of the outstanding indebtedness to TWE
       has been accounted for as an equity transaction.
 
    6.  Six Flags incurred approximately $27.5 million in deferred financing
       fees and approximately $7.5 million in transaction fees related to the
       1995 Refinancing and Recapitalization. The amount paid for transaction
       fees has been accounted for as an equity transaction. In addition, the 2%
       participation in a trust, which holds all TWE-owned aircraft, ceased upon
       the consummation of the 1995 Refinancing and Recapitalization. The
       elimination of the remaining net book value of this 2% interest
       (approximately $1.8 million) has been accounted for as an equity
       transaction.

consists of the cost of food and beverages, gifts and souvenirs, games of skill
prizes and gasoline sold. During 1997, the Company reversed approximately $7.3
million of expense accruals no longer deemed necessary. Such amounts have been
reflected as expense reductions of $0.7 million in cost of products sold, and
$6.6 million in operating, general and administrative expenses in the current
year statement of operations.
 
INCOME TAXES
 
    The Company uses the liability method of accounting for income taxes
required by FASB Statement No. 109, "Accounting for Income Taxes".
 
CASH EQUIVALENTS
 
    Cash equivalents consist of short-term, highly liquid investments purchased
with a maturity date of three months or less.
 
INVENTORIES
 
    Inventories, primarily products held for resale, are valued at the lower of
cost or market. Cost is determined principally using the first-in, first-out
method.
 
OFF-SEASON EXPENSES
 
    Theme park operations are highly seasonal with substantially all revenues
being generated in the second and third quarters. Such revenues are recognized
when earned, while cost of products sold, general and administrative expenses,
interest on debt and income taxes are recognized when incurred. All other
interim period costs related to park operations are considered off-season
expenses and are charged to interim periods based upon estimated annual
revenues. No costs are deferred at the end of a fiscal year.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment, which includes land, rides and attractions,
buildings and improvements, and other (principally machinery and equipment) are
stated at cost (fair value at the date of acquisition). Depreciation is computed
for financial reporting purposes using the straight-line method over the
estimated useful lives of the assets. The estimated lives used in computing
depreciation are:

INVESTMENT IN CO-VENTURE PARKS
 
    The Company, through two subsidiaries, is the general partner in two theme
park limited partnerships. The Company accounts for the parks as co-ventures,
i.e., the revenues and expenses (excluding partnership depreciation) are
included in the Company's consolidated statements of operations and the net
amounts distributed to the limited partners are deducted as expenses. Except for
the limited partnership units purchased pursuant to the tender offer, the
Company has no rights or title to the co-

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
venture park assets or to the proceeds from any sale of the co-venture park's
assets. Accordingly, the Company's consolidated balance sheets do not include
any of the co-venture parks' assets. The investment in co-venture parks included
in the consolidated balance sheets represents (i) the Company's interest in the
estimated future cash flows from the operations of the co-venture parks and is
amortized over the life of the partnership agreements, and (ii) the value of
Limited Partnership units purchased pursuant to the SFOG tender offer. The
co-venture parks contributed revenues of $176.8 million, $152.0 million and
$160.6 million to the Company in the fiscal years 1997, 1996 and 1995,
respectively. See the Investment In Co-venture Parks footnote below for a
description of the new agreements extending the management of Six Flags Over
Georgia and Six Flags Over Texas, each for another 30-year term.
 
DEFERRED FINANCING COSTS
 
    Deferred financing costs consist of debt issuance costs incurred in
connection with the Credit Agreement, the issuance of the 12.25% Notes and the
issuance of the $192.3 million aggregate principal amount of Zero Coupon Senior
Notes due 1999 (the "Zero Coupon Notes") in December 1992. Deferred financing
costs are amortized over the life of the related debt. Accumulated amortization
of deferred financing costs at December 28, 1997 and December 29, 1996 amounted
to $12.0 million and $8.3 million, respectively.
 
EXCESS OF COST OVER NET ASSETS ACQUIRED
 
    The excess of cost over net assets acquired is amortized over periods not
exceeding forty years using the straight-line method. Accumulated amortization
at December 28, 1997 and December 29, 1996 amounted to $47.7 million and $39.6
million, respectively.
 
OTHER ASSETS
 
    Other assets consist primarily of intangible assets, which are amortized
over periods of two to thirteen years using the straight-line method.
Additionally, in 1997, other assets include a $10.7 million prepayment in
accordance with the Texas Agreements. See Investment In Co-venture Parks
footnote.
 
REVENUE RECOGNITION
 
    In general, the Company recognizes operating revenue from ticket sales when
guests are admitted to the parks. Theme park operations are highly seasonal and
substantially all revenues are generated in the second and third quarters of the
fiscal year.
 
CONCENTRATIONS OF CREDIT RISKS
 
    Financial instruments, which potentially subject the Company to
concentrations of credit risk, consist primarily of cash and cash equivalents
and receivables. The Company places its cash and cash equivalents with high
credit, quality institutions and minimizes its credit risk exposure relating to
receivables through formal credit policies and monitoring procedures.
 
FINANCIAL INSTRUMENTS
 
    The fair value of financial instruments, such as long-term debt, is
disclosed when significantly different from the recorded values of such
instruments in the consolidated balance sheets pursuant to FASB Statement No.
107, "Disclosure about Fair Value of Financial Instruments." The Company
generally estimates the fair value of its long-term debt by using discounted
cash flow analyses based on the
 
                                      F-10
<PAGE>
                      SIX FLAGS ENTERTAINMENT CORPORATION
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
Company's current borrowing rates for debt with similar maturities, or by quoted
market prices for the same issues.
 
USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the amounts reported in the consolidated financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
    The carrying value of long-lived assets, including intangibles, is reviewed
if the facts and circumstances, such as significant declines in revenues,
earnings or cash flows, or material adverse changes in the business climate,
suggest that it may be impaired. Six Flags performs its review by comparing the
book value relating to long-lived assets to the estimated future undiscounted
cash flows relating to such long-lived assets. If any impairment in the value of
the long-lived assets is indicated, the carrying value of the long-lived assets
is adjusted to reflect such impairment calculated based on the discounted cash
flows of the impaired assets or the assets fair value, as appropriate.
 
ADVERTISING
 
    Advertising costs are expensed as incurred or the first time the advertising
takes place. The Company incurred advertising costs of approximately $61.1
million, $64.6 million and $53.4 million in the 1997, 1996 and 1995 fiscal
years, respectively.

                      SIX FLAGS ENTERTAINMENT CORPORATION
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
SIX FLAGS OVER GEORGIA
 
    On March 18, 1997, Six Flags, SFEC, Time Warner and TWE completed
arrangements pursuant to which SFOG II will manage the Six Flags Over Georgia
Park through 2026. Under the agreements governing the new arrangements (the
"Georgia Agreements"), the Six Flags Over Georgia Park is owned by a newly
formed limited partnership ("Six Flags Over Georgia II") of which SFOG II is the
managing general partner.
 
    The key elements of the new arrangements are as follows: (i) the limited
partner (which is not affiliated with Six Flags) will receive minimum annual
distributions of $18.5 million in 1997, increasing each year thereafter in
proportion to increases in the cost of living; thereafter, SFOG II will be
entitled to receive from available cash (after provision for reasonable reserves
and after capital expenditures per annum of approximately 6% of prior year
revenues) a management fee equal to 3% of the prior year's gross revenues; and,
thereafter, any additional available cash will be distributed 95% to SFOG II and
5% to the limited partner; (ii) in the second quarter of 1997, a subsidiary of
Six Flags (the "Six Flags Subsidiary") and a subsidiary of SFEC (the "SFEC
Subsidiary") made a tender offer for partnership interests ("SFOG LP Units") in
Six Flags Fund, Ltd. (L.P.), which owns 99% of the limited partner of Six Flags
Over Georgia II, that valued the Six Flags Over Georgia Park at $250 million
(the "SFOG Tender Offer Price"); (iii) commencing in 1998, and on an annual
basis thereafter, the Six Flags Subsidiary and the SFEC Subsidiary will offer to
purchase additional SFOG LP Units at a price based on the greater of the SFOG
Tender Offer Price or the EBITDA of the Six Flags Over Georgia Park for the
prior four years (provided that no more than $50 million of such SFOG LP Units
will be acquired by the Six Flags Subsidiary); and (iv) in 2026, Six Flags and
its affiliates will have the option to acquire the Six Flags Over Georgia Park
at a price based on the Tender Offer Price, increased in proportion to the
increase in the cost of living between December 1996 and December 2026. SFEC,
Six Flags, and TWE have guaranteed certain of the obligations (including the
minimum annual distributions noted in (i) above) of SFOG II and Six Flags Over
Georgia II under the Georgia Agreements, and in consideration therefor, SFOG II
has agreed to assign to Six Flags at least 90% of the cash distributions it
receives from time to time from Six Flags Over Georgia II. Six Flags continues
to account for the Six Flags Over Georgia Park as a co-venture and includes the
revenues and expenses of Six Flags Over Georgia II partnership (excluding
partnership depreciation) in Six Flags' consolidated financial statements and
deducts as expenses the net amounts distributed to the limited partners. As a
result of entering into the Georgia Agreements, Six Flags expects a reduction in
net income and net cash flow allocation from Six Flags Over Georgia II.
 
    On May 6, 1997, in connection with the closing of the tender offer described
above, the Six Flags Subsidiary and the SFEC Subsidiary purchased approximately
17% and 8%, respectively, of SFOG LP Units for approximately $42.4 million and
$20.3 million, respectively. The purchase of SFOG LP Units entitles each such
purchaser the right to receive minimum annual distributions and any residual
distributions (5% of available cash after the minimum annual distributions and
management fee distributions) in proportion to the percentage amounts purchased.
The purchase of SFOG LP Units by the Six Flags Subsidiary was financed through a
drawdown on the Company's secured revolving line of credit available for
acquisitions under the Credit Agreement and the purchase of SFOG LP Units by the
SFEC Subsidiary was financed through loans from TWE, which were subsequently
refinanced with demand loans from Chase. See Long-Term Debt footnote.
 
    In connection with the purchase of the SFOG LP Units, approximately $49.8
million of the excess of cost over net assets acquired associated with this
investment is being amortized over 30 years. The net

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
investment in SFOG LP Units is presented as part of the investment in co-venture
parks. Accumulated amortization at December 28, 1997 amounted to $2.6 million.
 
SIX FLAGS OVER TEXAS
 
    On November 24, 1997, Six Flags, SFEC, Time Warner and TWE completed
arrangements pursuant to which Six Flags Over Texas, Inc., a wholly-owned
subsidiary of Six Flags ("SFOT"), will manage the Six Flags Over Texas Park
through 2027. Under the agreements governing the new arrangements (the "Texas
Agreements"), the Six Flags Over Texas Park will continue to be owned by Texas
Flags Ltd., a limited partnership ("Six Flags Over Texas") of which SFOT is the
managing general partner.
 
    The key elements of the new arrangements are as follows: (i) the limited
partner (which is not affiliated with Six Flags) will receive minimum annual
distributions of $27.7 million in 1998, increasing each year thereafter in
proportion to increases in the cost of living; thereafter, SFOT II will be
entitled to receive from available cash (after provision for reasonable reserves
and after capital expenditures per annum of approximately 6% of prior year
revenues) a management fee equal to 3% of the prior year's gross revenues; and,
thereafter, any additional available cash will be distributed 92.5% to SFOT and
7.5% to the limited partner; (ii) in the first quarter of 1998, a subsidiary of
Six Flags and a subsidiary of SFEC have commenced a tender offer for partnership
interests ("SFOT LP Units") in Six Flags Over Texas, Ltd., which owns 99% of the
limited partner of Six Flags Over Texas, that values the Six Flags Over Texas
Park at the greater of $375 million or 8.5 times 1998 EBITDA of the Six Flags
Over Texas Park (the "SFOT Tender Offer Price"); (iii) commencing in 1999, and
on an annual basis thereafter, the Six Flags Subsidiary and the SFEC Subsidiary
will offer to purchase additional SFOT LP Units at a price based on the EBITDA
of the Six Flags Over Texas Park for the prior four years; and (iv) in 2027, Six
Flags and its affiliates will have the option to acquire the Six Flags Over
Texas Park at a price based on the SFOT Tender Offer Price, increased in
proportion to the increase in the cost of living between December 1997 and
December 2027. SFEC, Six Flags and TWE have guaranteed certain of the
obligations (including the minimum annual distributions noted in (i) above) of
SFOT under the Texas Agreements. Six Flags intends to continue to account for
the Six Flags Over Texas Park as a co-venture and to include the revenues and
expenses of Texas Flags partnership (excluding partnership depreciation) in Six
Flags' consolidated financial statements and deduct as expenses the net amounts
distributed to the limited partners. As a result of entering into the Texas
Agreements, Six Flags expects a reduction in net income and net cash flow
allocation from Texas Flags.
 
    In connection with the entering into the Texas Agreements, a subsidiary of
SFEC loaned $10.7 million to Texas Flags Ltd. during December 1997 as a
prepayment of its obligations under the Texas Agreements. This amount has been
included in other assets, net as of December 28, 1997.
 
    The tender offer for SFOT LP Units commenced on January 23, 1998 and is
expected to close on March 12, 1998. The Company will purchase these units
through the SFEC Subsidiary and will finance the purchase of such units through
loans from a syndicate of lenders.

    CREDIT AGREEMENT
 
    In 1995, the Company entered into a $600 million Credit Agreement with a
group of lenders. The Credit Agreement consists of a $345 million Tranche A
Senior Secured Term Loan Facility (the "Tranche A Term Facility"), a $130
million Tranche B Senior Secured Term Loan Facility (the "Tranche B Term
Facility")(together the "Term Facilities"), and a Senior Secured Revolving
Credit Facility (the "Revolving Facility"). The Revolving Facility provides for
revolving loans to the Company and the issuance of letters of credit for the
account of the Company in an aggregate principal amount of up to $125 million,
of which not more than $12 million may be represented by letters of credit. The
interest rates per annum applicable to the Tranche A Term Facility and Revolving
Facility are LIBOR plus 2.50%, as adjusted semi-annually. The interest rate per
annum applicable to the Tranche B Term Facility is LIBOR plus 3.00%, as adjusted
semi-annually. The amounts outstanding under the Term Facilities were $307.5
million at December 28, 1997. The amounts borrowed against the Revolving
Facility as of December 28, 1997 were $41 million. At December 29, 1996, there
were no amounts borrowed against the Revolving Facility. As of December 28,
1997, the Company had $9.3 million in letters of credit outstanding.
 
    Borrowings under the Tranche A Term Facility are payable as to principal in
July and September of each year through 2001. Borrowings under the Tranche B
Term Facility are payable in July and September

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
of each year through 2002 and in June 23, 2003. The Company is required to make
mandatory prepayments of loans, and letters of credit will be mandatorily
reduced based on certain criteria, as defined in the Credit Agreement.
 
    At least once during the period from June 30 to August 31 in each fiscal
year, the Company must repay all loans outstanding under the Revolving Facility
in excess of an amount equal to the lesser of (a) $50.0 million and (b) the
principal amount of loans then outstanding under the Revolving Facility that
were used to finance related business acquisitions. The Company may not make
drawings under the Revolving Facility for 30 consecutive days following the date
of such repayment. During such period, the Company must also cause each
co-venture park limited partnership to repay all amounts outstanding under their
unsecured credit lines and not to make drawings thereunder for 30 consecutive
days following the date of such repayment.
 
    The obligations of the Company under the Credit Agreement are
unconditionally and irrevocably guaranteed by each of the Company's direct or
indirect subsidiaries, other than the co-venture partnerships and certain
special purpose subsidiaries. In addition, the Credit Agreement is secured by
first priority security interests in all capital stock and other equity
interests of the Company and its subsidiaries.
 
    The Company is required to pay a per annum fee equal to 2.50%, plus a
fronting fee of 0.25%, of the aggregate face amount of outstanding letters of
credit under the Revolving Facility and a per annum fee equal to 0.50% on the
undrawn portion of the commitments in respect of the Revolving Facility.
Commitment fees totaled $0.4 million, $0.6 million and $0.3 million in 1997,
1996 and 1995, respectively.
 
    The Credit Agreement contains a number of significant covenants that, among
other things, restricts the ability of the Company to dispose of assets, incur
additional indebtedness, repay other indebtedness, amend material agreements,
pay dividends, create liens on assets, enter into leases, make investments or
acquisitions, engage in mergers or consolidations, make capital expenditures, or
engage in certain transactions with subsidiaries and affiliates and will
otherwise restrict corporate activities. In addition, under the Credit Agreement
the Company is required to comply with specified financial ratios and tests,
including cash interest expense coverage, debt service coverage and debt to
earnings ratios. The Credit Agreement also contains provisions that prohibit any
modification of the indenture governing the Notes in any manner adverse to the
lenders under the Credit Agreement and that limit the Company's ability to
refinance the Notes without the consent of such lenders.
 
    In December 1995, the Company entered into no-cost interest rate collar
transactions with certain lenders (or their affiliates) under the Credit
Agreement. The interest rate collar transactions effectively protect against an
increase in the three month LIBOR above 7% but limits the Company's ability to
benefit from a decline in the three month LIBOR below 4.55% with respect to $172
million, $150 million and $130 million notional amounts of debt during the 1996,
1997 and 1998 fiscal years, respectively. Interest payments/receipts on these
interest rate collar agreements will be made quarterly. No such
payments/receipts occurred through December 28, 1997.
 
    The fair value of the Credit Agreement and related interest rate collar
transactions approximated their carrying value as of December 28, 1997 and
December 29, 1996.
 
    SENIOR SUBORDINATED DISCOUNT NOTES
 
    The Company issued the 12.25% Notes on June 23, 1995 (the "Issue Date")
pursuant to an Indenture dated as of such date, among the Company, the Note
Guarantors and United States Trust Company of New York, as trustee. In November
1995, the Company offered to exchange $285.0 million aggregate principal amount
of its 12.25% Series A Senior Subordinated Discount Notes due 2005 (the "Series

Notes" and, together with the 12.25% Notes, the "Notes") for a like principal
amount of its 12.25% Notes. The exchange offer expired on December 18, 1995, and
$283.5 million aggregate principal amount of the Series A Notes were exchanged
for an equal principal amount of 12.25% Notes. The Series A Notes are governed
by the same indenture as, and are substantially identical to, the 12.25% Notes.
However, unlike the 12.25% Notes, the Series A Notes were issued in a
transaction registered under the Securities Act of 1933, as amended.
 
    The Notes are and will be unsecured senior subordinated obligations of Six
Flags, limited to $285.0 million aggregate principal amount, maturing on June
15, 2005. The Notes will accrete in value for purposes of the Indenture until
June 15, 1998, at which time the accreted value of the Notes will equal 100% of
their principal amount ($285 million). Interest payable in cash will not accrue
or be payable prior to June 15, 1998; thereafter, the accreted value of the
Notes will no longer increase and cash interest will be payable semi-annually on
June 15 and December 15 of each year, commencing December 15, 1998, at a rate of
12.25% per annum.
 
    The Notes will be redeemable, at the Company's option, in whole or in part,
at any time on or after June 15, 2000 through maturity. If redeemed during the
12-month period commencing on June 15 of the years set forth below, the Company
will be required to pay the following redemption prices:

    In addition, at any time prior to June 15, 1998, the Company may, subject to
certain requirements, redeem Notes having a principal amount of up to 35% of the
original aggregate principal amount of the Notes with the net cash proceeds of
one or more public equity offering by the Company at a redemption price equal to
112.25% of the accreted value of the Notes to be redeemed as of the redemption
date; provided, however, that at least 65% of the original aggregate principal
amount of the Notes must remain outstanding.
 
    The fair value of the Notes, estimated based on the quoted market prices,
was $303.5 million and $230.1 million at December 28, 1997 and December 29,
1996, respectively.
 
    The Notes are guaranteed on an unsecured, senior subordinated basis by Six
Flags Over Georgia, Inc., Six Flags Over Texas, Inc. and S.F. Partnership (the
"Note Guarantors"), each of which is a wholly-owned subsidiary of the Company.
 
    ZERO COUPON NOTES
 
    The Zero Coupon Notes are unsecured obligations of the Company issued under
an Indenture dated as of December 16, 1992, as amended, between the Company, TWE
and the United States Trust Company of New York, as trustee (the "Indenture").
The Zero Coupon Notes may not be redeemed prior to maturity and there will be no
periodic payments of interest over the life of the Zero Coupon Notes.
 
    TWE has unconditionally and irrevocably agreed that upon a failure by the
Company to pay the principal amount of the Zero Coupon Notes upon maturity, or
to pay the Accreted Value Amount (as defined in the Indenture) upon a
declaration of acceleration following a Secondary Event of Default (as defined
in the Indenture), TWE will offer to purchase the Zero Coupon Notes from the
holders thereof at

a predetermined price. TWE's obligation to make the offer to purchase will rank
PARI PASSU with all other unsecured and unsubordinated obligations for money
borrowed of TWE.
 
    The fair value of the Notes, estimated based on the quoted market prices,
was $170.1 million and $154.3 million at December 28, 1997 and December 29,
1996, respectively.
 
STOCKHOLDERS' EQUITY
 
    Pursuant to the 1995 Refinancing and Recapitalization, the Company's
outstanding equity consists of 5,100,000 shares of Class A Convertible Preferred
Stock, par value $.01 per share, 4,900,000 shares of Class B Convertible
Preferred Stock, par value $.01 per share, 51 shares of Class A Common Stock,
par value $.01 per share ("Class A Common Stock"), and 49 shares of Class B
Common Stock, par value $.01 per share ("Class B Common Stock"). The Class A
Convertible Preferred Stock has a liquidation preference per share of $40 plus
accrued and unpaid dividends to the liquidation date. Dividends accrue on the
outstanding shares of Class A Convertible Preferred Stock on a daily basis at
the rate of 12% per annum, compounded semi-annually on December 1 and June 1 of
each year. Accrued and unpaid dividends for the Class A Convertible Preferred
Stock were $69.5 million and $39.6 million at December 28, 1997 and December 29,
1996, respectively. The Class B Convertible Preferred Stock has a liquidation
preference per share of $40. No dividends shall accrue on the Class B
Convertible Preferred Stock. Members of the Investor Group own 51% of the equity
of the Company, consisting of all of the outstanding shares of Class A
Convertible Preferred Stock and Class A Common Stock, and TWE owns 49% of the
equity of the Company, consisting of all of the outstanding shares of Class B
Convertible Preferred Stock and Class B Common Stock. The Company's Class A
Convertible Preferred Stock and Class A Common Stock are further divided into
shares of voting stock (known as Class A-1 Convertible Preferred Stock and Class
A-1 Common Stock, respectively) and non-voting stock (known as Class A-2
Convertible Preferred Stock and Class A-2 Common Stock, respectively). The
non-voting shares of each such class were created for the benefit of certain
regulated entities (each a "Regulated Holder") whose ability to own voting stock
is restricted. Shares of Class A-1 Convertible Preferred Stock and Class A-1
Common Stock may be exchanged by a Regulated Holder on a share-for-share basis
for non-voting shares of such class. Shares of Class A-2 Convertible Preferred
Stock and Class A-2 Common Stock may be exchanged on a share-for-share basis for
voting shares of each such class if such shares are held by a person other than
by a Regulated Holder. Except for voting rights specifically accorded to a
particular class under Delaware law, the shares of Class A-1 Common Stock and
Class B Common Stock vote together as a single class on matters requiring
stockholder action.
 
    The Company has entered into an Employment Agreement ("the Agreement") with
an Executive (the "Executive") whereby the Company agrees to reserve for
issuance a certain number of shares of Class B Common Stock (the "Reserved
Shares"), as defined in the Agreement. The Reserved Shares will become vested on
December 31, 2000, subject to the Executive's employment having continued
through such date or prior thereto if certain events occur as defined in the
Agreement. Upon vesting of the Reserved Shares, the Executive will be entitled
to receive from the Company, in addition to the issued shares, any dividends or
distributions had such shares been issued and outstanding at the time that such
dividends or distributions were declared and paid as defined in the Agreement.
The Company has recognized compensation expense related to the Reserved Shares
during 1997 and 1996.
 
    Under the Agreement, the Executive was also granted options to purchase
shares of the Company's Class B Common Stock. The options include an option to
purchase an additional 163,936 shares of the Company's Class B Common Stock (the
"Tranche 1 Option"), and a second option to purchase an additional 327,872
shares of the Company's Class B Common Stock (the "Tranche 2 Option"). The

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
exercise price of the Tranche 1 Option is based on a September 1995 exercise
price of $40.64 per share, increasing at a cumulative annual rate of 10%. The
exercise price of the Tranche 2 Option is based on a September 1995 exercise
price of $40.94, increasing at a cumulative annual rate of 15%. On each
September 15 while the Executive is employed under Agreement, the number of
shares of the Company's Class B Common Stock reserved for issuance under the
terms of the Tranche 1 Option will decrease by 5,858.9 shares, at which time the
Executive will be granted a like number of additional Reserved Shares. In
addition, the Company granted additional options for the purchase of 327,872
shares of the Company's Class B Common Stock to members of management of the
Company and its subsidiaries. The terms of these options will be similar to the
Tranche 1 Option and Tranche 2 Option described above.
 
    The options become exercisable only if there is a triggering event, as
defined in the stock option plan agreement. Accordingly, these stock options
have been treated as if they were unissued due to the uncertainty regarding the
Executive's and other management employees' ability to exercise such options.
 
    In 1995, the Financial Accounting Standards Board issued SFAS. No. 123,
"Accounting for Stock-Based Compensation," which permits either recording the
estimated value of stock-based compensation over the applicable vesting period
or disclosing such cost in the notes to the financial statements. Six Flags has
adopted the disclosure-only provisions of SFAS 123. Had compensation cost for
the stock options been determined consistent with SFAS 123, the proforma effect
would not be significant.
 
PENSION PLAN
 
    Six Flags maintains a noncontributory, defined benefit pension plan (the
"Plan") covering substantially all of Six Flags' full-time employees. The Plan
permits normal retirement at age 65, with early retirement at ages 55 through 64
upon attainment of ten years of credited service. The early retirement benefit
is reduced for benefits commencing before age 62. Plan benefits are calculated
according to a benefit formula based on age, average compensation over the
highest consecutive five-year period during the employee's last ten years of
employment and years of service. Plan assets are invested primarily in common
stocks and mutual funds. The Plan does not have significant liabilities other
than benefit obligations. Under Six Flags' funding policy, contributions to the
Plan are determined using the projected unit credit cost method. This funding
policy meets the requirements under the Employee Retirement Income Security Act
of 1974.

SAVINGS PLAN
 
    Under the provisions of the Six Flags' savings plan, all full-time and
seasonal employees of Six Flags completing one year of service (minimum 1,000
hours) and attaining age 21 are eligible to participate and may contribute up to
6% of compensation as a tax deferred basic contribution. Each participant may
also elect to make additional contributions of up to 10% of compensation (up to
4% tax deferred). Tax deferred contributions to the savings plan may not exceed
amounts defined by the Internal Revenue Service ($9,500 for 1997). Both the
basic and additional contributions are at all times vested. Six Flags, at its
discretion, may make matching contributions of up to 100% of its employees'
basic contributions. Six Flags plans to make $0.9 million in contributions for
the 1997 plan year. Six Flags contributed $0.7 million for each of the 1996 and
1995 Plan years, representing up to 30% of the employees' basic contributions.
Six Flags matching contributions to the savings plan are made in the first
quarter of the succeeding year.

    Realization of deferred tax assets associated with the net operating loss
carryforwards is dependent upon generating sufficient taxable income prior to
their expiration. Management believes that there is a risk that certain of these
net operating loss carryforwards may expire unused and, accordingly, has
established a valuation allowance against them. Although realization is not
assured for the remaining deferred tax assets, management believes it is more
likely than not that they will be realized through future taxable earnings or
alternative tax strategies.
 
    At December 31, 1997, the Company has approximately $123.0 million of net
operating loss carryforwards, which expire through 2012.

RELATED PARTY TRANSACTIONS
 
TRANSACTIONS WITH TIME WARNER ENTERTAINMENT COMPANY, L.P. AND AFFILIATES
 
    On December 31, 1997, TWE contributed $4.0 million to the Company pursuant
to an agreement with the Investor Group. This capital contribution is reflected
as an affiliate receivable as of December 28, 1997.
 
    On May 5, 1997, TWE loaned $19.5 million to a subsidiary of the Company. The
proceeds from this affiliate loan were used to purchase approximately 8% of SFOG
LP Units pursuant to the tender offer for such units. On December 23, 1997, this
affiliate loan, along with accrued interest, was refinanced with Chase. On
November 24, 1997, TWE loaned $10.7 million to another Company subsidiary. The
proceeds of this affiliate loan were loaned to Texas Flags Ltd. in connection
with the Texas Agreements. See the Investment In Co-venture Parks footnote.
 
    In 1997 and 1996, Six Flags reimbursed TWE and its affiliates $2.6 million
and $4.4 million, respectively, for royalties on merchandise, advertising and
other expenses. Employees of a subsidiary of TWE served as senior management of
Six Flags during 1995. Costs associated with this management team, including
compensation and overhead, were charged to Six Flags by TWE. During 1995, Six
Flags was also allocated costs for additional services from TWE, including
accounting services, insurance coverage, transportation, and other services.
Costs allocated from TWE were at a level agreed upon by TWE and Six Flags. Six
Flags believes that this method of allocation was reasonable and that the
allocated costs approximated the costs which would have been incurred on a
stand-alone basis. In 1995, Six Flags recorded approximately $5.3 million for
merchandise royalties, advertising, and other expenses, as well as compensation,
overhead and other services allocated to Six Flags by TWE. Liabilities relating
to such amounts are included in other long-term liabilities in the accompanying
consolidated balance sheets. There were no costs allocated from TWE subsequent
to June 23, 1995.
 
    As part of the 1995 Refinancing and Recapitalization, the Company entered
into a new license agreement (the "License Agreement") pursuant to which it
obtained the exclusive right for a term of 55 years to theme park use in the
United States and Canada (excluding the Las Vegas, Nevada metropolitan area) of
all animated, cartoon and comic book characters that Warner Bros. and DC Comics
have the right to license for such use during the term of the agreement,
including all characters which, prior to the effectiveness of the License
Agreement, already had been licensed by Warner Bros. and DC Comics to the
Company for use in connection with the Company's theme parks.
 
    Under the License Agreement, the Company will pay an annual license fee of
$500,000 for each of the first ten years of the license term. Thereafter, the
license fee will be subject to periodic scheduled increases and will be payable
on a per-theme park basis. The annual license fees will also be increased by
amounts equal to any third-party payments which may be payable by Warner Bros.
or DC Comics as a result of the use of any licensed character by the Company.
 
    The Company entered into an amendment to the License Agreement ("Amendment #
1") which provides the exclusive right for a period of 3 years ending December
31, 1998, to theme park use of elements contained in released versions of
certain theatrical motion pictures and television shows, along with usage of the
"Warner Bros. Backlot Logo" (the "Logo Usage"). Each separate motion picture,
television series and/or Logo Usage may be utilized only in connection with live
shows within the Company's parks. The Company was charged $400,000 in total for
the years 1997 and 1996 and will be charged $150,000 in 1998 for the rights
granted pursuant to Amendment # 1.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
    In addition to the annual license fees described above, the Company is also
required to pay royalties on sales of products incorporating the licensed
characters at standard royalty rates for such products, subject to increase from
time to time. Warner Bros. will be entitled to terminate the License Agreement
prior to the expiration of the stated term if the Company, at any time during
the term, is directly or indirectly controlled by a person that derives
significant revenues from the production or distribution of motion pictures or
engages in certain other businesses competitive with TWE.
 
    The Company also entered into a license agreement with TWE pursuant to which
TWE granted the Company a 25-year license to use the trademarks and service
marks relating to the "Home Box Office" and "HBO" names and the "HBO" logo for
use in connection with the operation of restaurants in the Company's theme
parks. The TWE license is royalty-free for the first ten years of its term.
Thereafter, annual royalties will be established every five years. The Company
also entered into an agreement entitling the Company (i) to use the name "Time
Warner" in connection with operating a retail merchandise outlet with the name
"Time Warner Studio Store" at the Company's theme parks and for establishing a
themed area in each of the Company's theme parks to be called "Time Warner
Studios" and (ii) to stage a concert series in the Company's theme parks under
the name "Warner Music Rock Review." The Company also entered into a license
agreement with the Sports Illustrated division of Time Warner pursuant to which
Time Warner granted the Company a ten-year royalty-free license to use the
"Sports Illustrated" and "Sports Illustrated for Kids" trademarks and service
marks in connection with the operation of a sports festival at the Company's
theme parks. The licensor under each of these additional license agreements has
the right to terminate the license granted thereby if, during the stated term of
any such license agreement, the Warner Bros. License Agreement is terminated for
any reason. The licensor also has the right under certain circumstances to
suspend the right of any of the Company's theme parks to use the licenses
granted thereby if the license is not sufficiently utilized in such theme park.
 
    At January 1, 1995, Six Flags had amounts outstanding to TWE aggregating
$488.0 million. Interest expense relating to the amounts due to TWE for fiscal
year 1995 amounted to $18.0 million. At January 1, 1995, accrued interest on the
TWE debt amounted to $7.2 million. As part of the 1995 Refinancing, all amounts
due to TWE were repaid.
 
COMMITMENTS AND CONTINGENCIES
 
LEGAL PROCEEDINGS AND OTHER
 
    The Company is a party to lawsuits incidental to its business and against
which the Company believes it is adequately insured or which will not result in
losses material to the consolidated financial position or results of operations
of the Company.
 
    On March 19, 1997, the Company, and its wholly-owned subsidiary Six Flags
Over Georgia, Inc. (collectively, the "Six Flags Parties") commenced a
declaratory judgement action in the Superior Court of Gwinnett County, Georgia,
entitled Six Flags Over Georgia, Inc. and Six Flags Theme Parks, Inc. v. Six
Flags Fund, Ltd. and Avram Salkin, as Trustee of the Claims Court. The Six Flags
Parties sought, among other things, a declaration and determination of rights
and obligations of the partners of Six Flags Over Georgia, LP with respect to
certain disputed partnership affairs and an accounting of all partnership
affairs. On April 21, 1997, defendants Six Flags Fund Ltd. and its affiliates
(collectively, the "SFOG Fund Parties") filed a motion to discuss the
declaratory judgment action as well as an answer and counterclaim naming Six
Flags Entertainment Corporation and Time Warner Entertainment Company, LP as
additional counterclaim-defendants. The counterclaim seeks imposition of a
constructive trust, compensatory damages of in excess of $250 million and
unspecified punitive damages for alleged breaches of fiduciary duty, conversion,
fraud and conspiracy allegedly committed by the counterclaim-defendants in
connection with

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
the management of the Six Flags Over Georgia theme park (the "Georgia Park").
The Company and the other counterclaim-defendants intend to vigorously contest
these allegations.
 
    On June 9, 1997, the parties entered into a Consent Order in which they
agreed, among other things, to realign the parties. An Amended Complaint was
then filed by the SFOG Fund Parties as the newly aligned plaintiffs against the
Six Flags Parties in which the same substantive claims were asserted. The Six
Flags Parties filed their answer denying liability and asserting several
affirmative defenses on July 24, 1997. The Six Flags Parties intend to
vigorously contest the allegations of the complaint.
 
    On February 2, 1995, the Company entered into an agreement with the Jackson
Township Municipal Utilities Authority of New Jersey (the "Authority") which
provides for the extension of the Authority's sanitary sewer collection
facilities to Six Flags Great Adventure ("SFGA"), the Company's theme park
located in Jackson, New Jersey, and connection of the SFGA property to such
facilities. SFGA will be entitled to utilize approximately 40% of the total
capacity of the extension and the Authority will waive SFGA's fees relating to
connecting to the extension. The Authority through the New Jersey Waste Water
Treatment Trust ("NJWWTT") plans to issue approximately $6.5 million of
tax-exempt bonds (the "Bonds") to finance the costs of the extension. The
Company has agreed to pay the Authority amounts equal to principal and interest
on the Bonds plus fees to the NJWWTT. Such debt service payments are estimated
at approximately $0.5 million per annum over the 20-year life of the bonds. In
addition, the Company has permitted the Authority to retain, as security, $0.9
million that the Authority currently owes to the Company. These amounts will be
repaid to the Company on a pro rata basis as the principal of the Bonds is
amortized. The Company will be entitled to credits against the debt service
payments as new users connect to the extension and pay for the 60% of capacity
not used by SFGA. The Company made the first principal and interest payment on
the bonds, approximately $0.2 million, during the first quarter of 1998.
 
LEASES
 
    Six Flags leases certain buildings, vehicles, equipment and rides under
operating leases. Vehicles are generally leased under a Fleet Lease Agreement,
which provides for early lease termination under certain conditions. All other
leases are generally noncancellable and may contain renewal options upon
expiration.
 
    Total rent expense for the fiscal years ended 1997, 1996 and 1995 was $9.7
million, $8.5 million and $12.0 million, respectively. Minimum future rent
payments totaling $16.0 million under commitments for noncancellable operating
leases in effect at the end of 1997 are payable as follows: $5.7 million in
1998, $4.3 million in 1999, $3.0 million in 2000, $1.9 million in 2001, $1.0
million in 2002 and $0.1 million for years thereafter.
 
SUBSEQUENT EVENT
 
    On February 9, 1998, TWE and Boston Ventures entered into an agreement with
Premier Parks Inc. ("Premier") to sell SFEC for approximately $1.9 billion.
Under the terms of the agreement, Premier will acquire 100% of the equity of
SFEC for $965 million, subject to adjustment, including $765 million in cash and
$200 million in convertible preferred stock of Premier. Premier will assume a
total of approximately $890 million of debt. As part of the transaction, the
companies will enter into a long-term licensing agreement that gives Premier the
exclusive theme park rights in the U.S. and Canada (excluding the Las Vegas,
Nevada Metropolitan area) of all Warner Bros. and DC Comics animated cartoon and
comic book characters. The transaction is expected to close in the second
quarter of 1998. These financial statements do not reflect any adjustments
relating to the consummation of the transaction.

    Premier expects to finance the transaction with approximately $700 million
of public equity and equity equivalents as well as public debt and bank
financing.
 
    The consummation of this transaction will cause the reserved shares and
options discussed in the Stockholders' Equity footnote to become vested and
exercisable, respectively.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 145 of the Delaware General Corporation Law which covers the
indemnification of directors, officers, employees and agents of a corporation is
hereby incorporated herein by reference. Reference is made to Article 9 of the
Company's By-Laws which provides for indemnification by the Registrant in the
manner and to the full extent permitted by Delaware law.
 
    Reference is also made to Section       of the Underwriting Agreement, to be
filed by amendment as Exhibit 1(a).
 
ITEM 16. EXHIBITS.
 
    See Exhibit Index.
 
ITEM 17. UNDERTAKINGS.
 
    (a) The undersigned Registrant hereby undertakes that, for the purposes of
determining any liability under the Securities Act of 1933 (the "Act"), each
filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of
the Securities Exchange Act of 1934 that is incorporated by reference herein
shall be deemed to be a new registration statement relating to the securities
offered herein, and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof.
 
    (b) Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Registrant,
pursuant to the foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
                                      II-1
<PAGE>
    (c) The undersigned Registrant hereby undertakes the following:
 
        (1) That, for purposes of determining any liability under the Act, the
    information omitted from the form of prospectus filed as part of this
    registration statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Act shall be deemed to be part of this registration
    statement as of the time it was declared effective.
 
        (2) That, for the purpose of determining any liability under the Act,
    each post-effective amendment that contains a form of prospectus shall be
    deemed to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
