                      SIX FLAGS REPORTS INTERIM PERFORMANCE

                                  -------

NEW YORK, July 17, 2003 - Six Flags, Inc. (the "Company") (NYSE: PKS) commented
today on the attendance and revenue performance of its parks for the month of
June and for the first six months of the year.

         System-wide attendance for the four weeks ended June 29 was 7.3
million, compared to 7.6 million in June 2002, a decrease of 4.0%, reflecting
the impact of significantly above average rainfall and below average
temperatures during the month in a number of key markets, as well as the effects
of a persistently weak economy. Park-level per capita spending was up 1.6% for
the period. Year to date through Sunday, June 29, system-wide attendance was
down 0.96 million, or 5.8%, from the first six months of 2002, and park-level
per capita spending was up slightly, by approximately 0.5%. Consequently,
results for the six months ended June 30 are now expected to reflect revenues
from consolidated operations of approximately $380-382 million, down
approximately $15-17 million from the 2002 period, EBITDA (Adjusted) from
Consolidated Operations of approximately $18-19 million, down approximately
$27-28 million from the 2002 six month levels, and Adjusted EBITDA including
Unconsolidated Operations of approximately

$19-20 million, down approximately $30-31 million from performance in the six
months ended June 30, 2002.(1)

         "Weather was clearly the predominant factor constraining our
performance through June, together with the continued impact of general economic
weakness," noted Kieran E. Burke, Chairman and Chief Executive Officer of the
Company. "Adverse weather in May and June not only affected park performance,
but also combined with weakness in the economy to hamper season pass sales,
which on a year-to-date basis through July 13 trail prior year sales system-wide
by approximately 7%. Group sales bookings have also weakened, reflecting both
the difficult economy and decreased school outings business as a result of
budgetary constraints and policies restricting travel related to terror alert
levels. System-wide, as of July 13, hard ticket attendance to date and future
bookings taken together are 1.2% behind 2002 levels.

         In the last few weeks, as the persistent pattern of unusually cool and
very wet weather through late June has abated, performance has improved.
System-wide attendance has outpaced prior year from June 22 through Sunday, July
13 by 1.0%, although per capita spending has decreased by 0.6% in the period.
However, even during this period, performance has been uneven. Therefore, we
cannot be certain if this trend will in fact continue through the balance of our
season. In any event, that pace is not sufficient, given the existing shortfall
to prior year, to achieve the revenues, EBITDA (Adjusted) from Consolidated
Operations and Adjusted EBITDA including Unconsolidated Operations on a full
year basis that we reached in 2002. The amount of the shortfall, which could be
material, will depend upon performance over the balance of the season,
especially the remainder of July and August. Based upon current performance
trends, we expect to remain in compliance with all covenants in our credit
agreements.

         We will be reporting our second quarter results in the second week of
August and will provide an estimate of full-year performance at that time.

         Six Flags, Inc. is the world's largest regional theme park company,
with thirty-nine parks in markets throughout North America and Europe.

reconciliation of these amounts, appears at the end of this press release.

         EBITDA (Adjusted) from Consolidated Operations is defined as net income
(loss), before cumulative effect of a change in accounting principle (in the
case of the 2002 period), income tax benefit, other expense, equity in
operations of theme parks, debt retirement (formerly extraordinary loss),
interest expense, net, depreciation, amortization and non-cash compensation.
Adjusted EBITDA including Unconsolidated Operations is defined as EBITDA
(Adjusted) from Consolidated Operations plus (i) the Company's equity in
operations of its four unconsolidated parks and (ii) depreciation and
amortization expense and third-party interest and other non-operating expenses
associated with those parks. The Company believes that EBITDA (Adjusted) for
Consolidated Operations and Adjusted EBITDA including Unconsolidated Operations
(collectively, the "EBITDA-Based Measures") provide useful information to
investors regarding the Company's operating performance and its capacity to
incur and service debt and fund capital expenditures. The Company believes that
the EBITDA-Based Measures are used by many investors, equity analysts and rating
agencies as a measure of performance. In addition, restrictive covenants in the
Company's senior credit facility contain financial ratios based on EBITDA
(Adjusted) from Consolidated Operations. Adjusted EBITDA including
Unconsolidated Operations is approximately equal to "Consolidated Cash Flow" as
defined in the indentures relating to the Company's senior notes. Neither of the
EBITDA-Based Measures is defined by GAAP and neither should be considered in
isolation or as an alternative to net income (loss), net cash provided by (used
in) operating, investing and financing activities or other financial data
prepared in accordance with GAAP or as an indicator of our operating
performance.

         The following table sets forth a reconciliation of net loss to EBITDA
(Adjusted) from Consolidated Operations and Adjusted EBITDA including
Unconsolidated Operations for the first six months of 2002.

         The Company currently is in the process of preparing its second quarter
2003 financial statements and does not at this time have reliable estimates for
its income tax benefit and other expense for that period. This information would
be required to provide an estimate of the Company's net loss for the first six
months of 2003. Because the net loss information is not available, the Company
has set forth in the following table a reconciliation of the expected loss from
operations to the expected EBITDA (Adjusted) from Consolidated Operations and
the expected Adjusted EBITDA including Unconsolidated Operations. Since the
EBITDA-Based Measures are calculated before income taxes and other expense, the
absence of estimates with respect to these items would not affect the expected
EBITDA-Based Measures presented. Expected interest expense, net for the six
months is approximately $107,100,000 and expected debt retirement (formerly
extraordinary loss) is approximately $27,600,000.
