Forward-looking statements can be identified by words such as “anticipates,” “intends,” “plans,” “seeks,” “believes,” “estimates,” “expects” and similar references to future periods. Examples of forward-looking statements include, but are not limited to, statements we make regarding the potential restructuring of the Company’s debt and equity securities, the Company's continued viability, the Company's operations and results of operations, the Company's shareholders, and the Company's customers. Forward-looking statements are based on our current expectations and assumptions regarding the Company's business, the economy and other future conditions. Because forward-looking statements relate to the future, by their nature, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict, including, among others, the Company's ability to successfully consummate the proposed restructuring, the Company's financial condition upon the consummation of any restructuring and the Company's success in implementing the Company's business strategy. The Company’s actual results may differ materially from those contemplated by the forward-looking statements. We caution you therefore that you should not rely on any of these forward-looking statements as statements of historical fact or as guarantees or assurances of future performance. Important factors that could cause actual results to differ materially from those in the forward-looking statements include regional, national or global political, economic, business, competitive, market and regulatory conditions and include the following: the failure to successfully consummate a restructuring as described herein; factors impacting attendance, such as local conditions, contagious diseases, such as swine flu, events, disturbances and terrorist activities; accidents occurring at the Company's parks; adverse weather conditions; competition with other theme parks and other entertainment alternatives; changes in consumer spending patterns; credit market and general economic conditions; pending, threatened or future legal proceedings; and the other factors that are described in “Risk Factors” in the Company's filings and submissions with the U.S. Securities and Exchange Commission (“SEC”), including the Company's most recent Annual Report on Form 10-K and the Company’s Current Reports on Form 8-K filed with the SEC on May 7, 2009 and July 23, 2009 and the Company’s Quarterly Report on Form 10-Q filed with the SEC on August 14, 2009. Any forward-looking statement made by us in this Presentation speaks only as of the date of this Presentation. Factors or events that could cause the Company's actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. Neither Houlihan Lokey nor the Company undertakes any obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise. THE PROJECTIONS WERE NOT PREPARED WITH A VIEW TOWARD PUBLIC DISCLOSURE OR COMPLIANCE WITH PRACTICES RECOGNIZED TO BE IN ACCORDANCE WITH THE GENERALLY ACCEPTED ACCOUNTING PRINCIPLES, PUBLISHED GUIDELINES OF THE SECURITIES AND EXCHANGE COMMISSION, THE RULES AND REGULATIONS PROMULGATED BY THE SECURITIES AND EXCHANGE COMMISSION REGARDING PROJECTIONS OR THE GUIDELINES ESTABLISHED BY THE AMERICAN INSTITUTE OF CERTIFIED PUBLIC ACCOUNTANTS REGARDING PROJECTIONS OR FORECASTS. FURTHERMORE, THE PROJECTIONS HAVE NOT BEEN AUDITED OR REVIEWED BY INDEPENDENT CERTIFIED ACCOUNTANTS.

Disclaimer 4 Non-GAAP Financial Measures The Company uses “Adjusted EBITDA”, “Modified EBITDA” and “Free Cash Flow” to assess the operating results and effectiveness of its business. These terms presented in this Presentation are supplemental measures of performance that are not required by, or recognized as being in accordance with, United States generally accepted accounting principles (“GAAP”). The Company believes that Adjusted EBITDA, Modified EBITDA and Free Cash Flow provide useful information to investors regarding its operating performance and its capacity to incur and service debt and fund capital expenditures. The Company believes that Adjusted EBITDA, Modified EBITDA and Free Cash Flow are used by many investors, analysts and rating agencies as a measure of performance. Adjusted EBITDA, Modified EBITDA and Free Cash Flow are not defined by GAAP and should not be considered in isolation or as alternatives to net income (loss), income (loss) from continuing operations, net cash provided by (used in) operating, investing and financing activities or any other financial data prepared in accordance with GAAP or as an indicator of its operating performance. Adjusted EBITDA, Modified EBITDA and Free Cash Flow as defined in this Presentation may differ from similarly titled measures presented by other companies. This information should be read in conjunction with the consolidated statements of operations and statements of cash flows contained in the Company’s Consolidated Financial Statements, which are included in its filings with the U.S. Securities and Exchange Commission (the “SEC”), including its most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q. Adjusted EBITDA is defined as Six Flags’ net income (loss) before cumulative effect of changes in accounting principles, discontinued operations, income tax expense (benefit), other expense, early repurchase of debt (formerly an extraordinary loss), equity in operations of partnerships, minority interest in earnings (losses), interest expense (net), amortization, depreciation, stock-based compensation, gain (loss) on disposal of assets, interests of third parties in the Adjusted EBITDA of four parks that are less than wholly owned (consisting of Six Flags Over Georgia, Six Flags Over Texas, Six Flags White Water Atlanta, and Six Flags Discovery Kingdom (formerly Six Flags Marine World, the minority interest in which we purchased in July 2007), plus the Company’s interest in the Adjusted EBITDA of Six Flags Great Escape Lodge & Indoor Waterpark (“HWP”) and dick clark productions, inc (“dcp”). Modified EBITDA is defined as Adjusted EBITDA plus the interests of third parties in the Adjusted EBITDA of the four parks that are less than wholly owned less the Company's interest in the Adjusted EBITDA of Six Flags Great Escape Lodge & Indoor Waterpark and dcp. Free Cash Flow is defined as Adjusted EBITDA excluding (i) cash interest expense (net) and debt issuance costs, dividends and taxes paid in cash and (ii) capital expenditures, net of property insurance recoveries. For the analyses included herein, Modified EBITDA, Adjusted EBITDA and Free Cash Flow all exclude the costs of the change in corporate management that occurred in December 2005 (approximately $13.9 million recognized as expense in 2006). Adjusted EBITDA, Modified EBITDA and Free Cash Flow have important limitations as analytical tools and you should not consider them in isolation or as substitutes for analysis of the Company’s results as reported under GAAP. For example, Adjusted EBITDA: excludes certain tax payments that may represent a reduction in cash available; does not reflect any cash capital expenditure requirements for assets being depreciated and amortized that may have to be replaced in the future does not reflect significant interest expense, or cash requirements necessary to service interest or principal payments on the Company’s debts. Additionally, Adjusted EBITDA, Modified EBITDA and Free Cash Flow do not reflect changes in or cash requirements for working capital. Certain of these items can represent a reduction of cash that could be used for other corporate purposes. Because of these limitations investors should rely primarily on the Company’s GAAP results and use Adjusted EBITDA, Modified EBITDA and Free Cash Flow only as supplemental information. The Company uses non-GAAP measures such as Adjusted EBITDA, Modified EBITDA and Free Cash Flow. Reconciliations of these measures to GAAP are available on the Company's website.

Long Range Plan Executive Summary Plan is based upon gradual economic recovery over the period rather than “hockey-stick” rebound Moderate top-line growth in attendance and per caps when added to solid sponsorship and licensing increases results in revenue growth exceeding industry multi-year forecasts Cash operating expenses increase modestly during the plan period at a CAGR of approximately 1% through tight cost control and continued efficiencies in labor, marketing, and benefits Top-line growth combined with prudent cost control generates Adjusted EBITDA growth at a 12% CAGR and a return to 30% Modified EBITDA margins Assuming a restructured Balance Sheet, as contemplated in the proposed restructuring plan, annual Free Cash Flow increases from approximately $60 million in 2010 to over $150 million in 2013 5

Alternative Plan Observations

Alternative Plan Observations Observations are based on review of limited top-line summaries of the Kings Leisure (“Kings”) business plan as described in presentations dated July 23rd, August 19th, and a Barclays presentation dated October 23rd REVENUE OBSERVATIONS Top-line revenue growth relies on season pass price reductions to drive volume, while also increasing ticket per cap on one-day tickets, and assuming attendance in both categories will grow meaningfully each year during the plan period THE ABOVE ASSUMPTION OF ATTENDANCE GROWTH IN BOTH CATEGORIES COUPLED WITH PRICE CONVERGENCE IS INHERENTLY FLAWED Kings suggests that prices are generally inelastic, but at the same time relies on significant reductions in season pass pricing which is counterintuitive Six Flags data would suggest that our prices are extremely elastic, e.g., 2006 price increases, 2008 EPKP value promotion, 2009 season pass price reductions Kings assumes that in-park per cap will also grow notwithstanding the significant increase in mix of season pass attendees; certainly not the industry norm Kings plan expects to grow attendance 1.5 million in 2010 and over 5 million by the end of the plan period This level of attendance growth is 4 million more than our plan in 2013 and over 1 million more than this portfolio of parks generated in 2005 with $165 million of capital expenditure While the above projected attendance growth generates nice returns on paper, we believe it is highly unrealistic and with guest spending per cap projected to drop $1.25 more than our plan due to price decreases, presents significant risk 28

Alternative Plan Observations (continued) COST OBSERVATIONS The Kings plan appears to contemplate reducing corporate costs by $25 million without any detail other than citing “industry benchmarks” of 2.5% of revenue while also citing 4.4 – 5.3% in “other organizations” Notwithstanding the corporate cost reductions, the Kings’ plan assumes sponsorship growth to $52 million during the plan period when in all likelihood the plan should expect to lose $25-30 million of annual revenue It is also worth noting that the total amount of operating expense and capital in the Kings plan for the years 2012 and 2013 is within $10 million of our combined expenses for 2012 and within $5 million for 2013, before considering any potential cost or capex reductions to our plan SUMMARY When the attendance does not materialize, in addition to losing $25-30 million in annual sponsorship revenue, the Kings’ plan will result in lost revenue of approximately $25 million per year from the incremental per cap decline, in addition to any severance and/or relocation costs associated with the corporate cost reductions, not to mention the brand perception and experience decline 29

Paramount Park Performance 2003 - 2005 Paramount Parks ran at an average 25.8% EBITDA margin from 2003 to 2005 with only direct allocation of corporate G&A Although revenue grew from $375MM to $423MM, EBITDA increased only $13MM Average annual Capex spend was $45MM (11.2% of revenue) on average on a company with revenues well less than half of Six Flags (5 PARKS) Quality fell; significant drop in one day ticket attendance Management team has relatively no sponsorship sales/fulfillment experience Most, if not all of the management team, was not retained by Cedar Fair 30

APPENDIX

APPENDIX Cedar Fair Comparison

Operating Performance Comparison Set forth below is a comparison of Six Flags, Inc.’s and Cedar Fair LP’s financial performance for each of FYE 2008 In order to demonstrate financial performance on a comparable basis, given Six Flags’ non-wholly owned parks (the “Partnership Parks”), this analysis compares Six Flags Modified EBITDA to Cedar Fair’s Adjusted EBITDA Comparison of Operating Results 33

Per Capita Comparison Per Cap Spending Comparison Cedar Fair’s EBITDA Margins were approximately 5.6 ppts higher than Six Flags’ EBITDA Margins in 2008 The difference is primarily attributable to its significant ticket per cap premium over Six Flags Cedar Fair is able to obtain higher ticket pricing from, among other things, a long-standing reputation of a stable product as well as hotel offerings allowing extended stays (1) For purposes of this analysis, Ticket and In-park Per Caps calculated as revenue, as provided in each company’s respective form 10Q and or 10K, divided by attendance. (2) For purposes of this analysis Total Guest Spend is as reported in each company’s form 10Q. Variations in Cedar Fair’s actual In-park and Out-of-park per capita due to reclassification of revenue items. 34

Operating Performance Pro Forma The following table represents the margin improvement assuming Six Flags could command Cedar Fair’s higher ticket pricing Assuming this single adjustment, Six Flags would have exceeded Cedar Fair’s EBITDA margin in 2008 35

Marketing Cost Comparison Due to the location of its parks, Six Flags has significantly higher marketing and advertising costs than Cedar Fair Six Flags’ parks are concentrated in high cost Designated Market Areas (“DMAs”), particularly on the East Coast, while Cedar Fair’s parks are concentrated predominately in the lower cost DMAs in the Midwest (see next page) As shown in the chart below, Six Flags spent approximately $37.7 million more on marketing and advertising than Cedar Fair in FYE 2008. The increased marketing costs account for 3.5% of the differential in Six Flags and Cedar Fair EBITDA margin 2008 Marketing Expense Comparison FYE December 2008 Six Flags Cedar Fair Difference Revenues $1,021.3 $996.2 Marketing and Advertising Expenses $93.1 $55.4 ($37.7) As % of Revenue 9.1% 5.6% ($ in millions) 3.5ppts 36

Geographic Footprint As shown in the chart below, Six Flags operates thirteen parks in the top ten DMAs in the United States while Cedar Fair operates only four parks in the top ten DMAs Six Flags’ Designated Market Areas Cedar Fair’s Designated Market Areas 37

Cost of Living Comparison Of the 18 US parks that Six Flags operates, 12 are in cities that have a cost of living that is over 10% greater than the US average Of those, 8 are over 20% higher than average Of the 16 US theme and water parks that Cedar Fair operates, 10 are in cities that have a cost of living that is lower than the US average Of those, 7 are in markets that are over 10% lower than the US average Of the 6 that are above average, 3 are water parks SOURCE: Sperling’s Best Places 38
