THIS NON-QUALIFIED STOCK OPTION AWARD AGREEMENT (this “Agreement”), dated as of the Grant Date specified above, is entered into by and between Six Flags Entertainment Corporation, a corporation organized in the State of Delaware (the “Company”), and the Participant specified above, pursuant to the Six Flags Entertainment Corporation Long-Term Incentive Plan, as in effect and as amended from time to time (the “Plan”), which is administered by the Committee;

WHEREAS, it has been determined under the Plan that it would be in the best interests of the Company to grant the Non-Qualified Stock Option provided for herein to the Participant; and

WHEREAS, the Executive and the Company are party to an Employment Agreement dated August 12, 2010 (the “Employment Agreement”).

NOW, THEREFORE, in consideration of the mutual covenants and promises hereinafter set forth and for other good and valuable consideration, the parties hereto hereby mutually covenant and agree as follows:

1.             Incorporation By Reference; Plan Document Receipt.  This Agreement is subject in all respects to the terms and provisions of the Plan (including, without limitation, any amendments thereto adopted at any time and from time to time unless such amendments are expressly intended not to apply to the Award provided hereunder), all of which terms and provisions are made a part of and incorporated in this Agreement as if they were each expressly set forth herein.  Any capitalized term not defined in this Agreement shall have the same meaning as is ascribed thereto in the Plan.  The Participant hereby acknowledges receipt of a true copy of the Plan and that the Participant has read the Plan carefully and fully understands its content.  In the event of any conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan shall control.  No part of the Option granted hereby is intended to qualify as an “incentive stock option” under Section 422 of the Code.

2.             Grant of Option.  The Company hereby grants to the Participant, as of the Grant Date specified above, a Non-Qualified Stock Option (this “Option”) to acquire from the Company at the Per Share Exercise Price specified above, the aggregate number of Shares specified above (the “Option Shares”).  Except as otherwise provided by the Plan, the Participant agrees and understands that nothing contained in this Agreement provides, or is intended to provide, the Participant with any protection against potential future dilution of the Participant’s interest in the Company for any reason.  The Participant shall have no rights as a stockholder with respect to any Shares covered by the Option unless and until the Participant has become the holder of record of such Shares, and no adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of any such Shares, except as otherwise specifically provided for in the Plan or this Agreement.

3.             Vesting and Exercise.

(a)           Vesting.  Subject to the applicable provisions of Section 4 of the Employment Agreement, the Option shall vest and become exercisable as follows, provided that the Participant has not incurred a termination of employment with the Company and its Subsidiaries (a “Termination”) prior to each such vesting date:

There shall be no proportionate or partial vesting in the periods prior to each vesting date and all vesting shall occur only on the appropriate vesting date, subject to the Participant’s continued service with the Company or any of its Subsidiaries on each applicable vesting date.  Upon expiration of the Option, the Option shall be cancelled and no longer exercisable.

(b)           Committee Discretion to Accelerate Vesting.  Notwithstanding the foregoing, the Committee may, in its sole discretion, provide for accelerated vesting of the Option at any time and for any reason.

(c)           Expiration.  Unless earlier terminated in accordance with the terms and provisions of the Plan and/or this Agreement, all portions of the Option (whether vested or not vested) shall expire and shall no longer be exercisable after the expiration of ten (10) years from the Grant Date.

(d)           Employment Agreement.  For the sake of clarity, Section 4 of the Employment Agreement shall apply to determine any accelerated vesting of the Award.

2

4.             Termination.   Subject to the terms of the Plan and this Agreement, the Option, to the extent vested at the time of the Participant’s Termination, shall remain exercisable as follows:

(a)           Termination Without Cause.  In the event of the Participant’s Termination for any reason, other than by the Company for Cause, the vested portion of the Option shall remain exercisable until the earlier of (i) ninety (90) days from the date of such termination, and (ii) the expiration of the stated term of the Option pursuant to Section 3(c) hereof; provided that if the Executive is entitled to any longer period of time to exercise the vested portion of the Option pursuant to the Employment Agreement, the terms of the Employment Agreement shall apply.

(b)           Termination for Cause.  In the event of the Participant’s Termination for Cause, the Participant’s entire Option (whether or not vested) shall terminate and expire upon such Termination.

(c)           Treatment of Unvested Options upon Termination.  Any portion of the Option that is not vested (determined after giving effect to any accelerated vesting of the Option) as of the date of the Participant’s Termination for any reason shall terminate and expire as of the date of such Termination.

5.             Method of Exercise and Payment.  Subject to Section 8 hereof, to the extent that the Option has become vested and exercisable with respect to a number of Shares as provided herein, the Option may thereafter be exercised by the Participant, in whole or in part, at any time or from time to time prior to the expiration of the Option as provided herein and in accordance with Sections 5(c) and 5(d) of the Plan, including, without limitation, by the filing of any written form of exercise notice as may be required by the Committee and payment in full of the Per Share Exercise Price specified above multiplied by the number of Shares underlying the portion of the Option exercised.

6.             Non-Transferability.  The Option, and any rights and interests with respect thereto, issued under this Agreement and the Plan shall not be sold, exchanged, transferred, assigned or otherwise disposed of in any way by the Participant (or any beneficiary of the Participant), other than by testamentary disposition by the Participant or the laws of descent and distribution.  Notwithstanding the foregoing, the Committee may, in its sole discretion, permit the Option to be transferred to a Permitted Transferee for no value, provided that such transfer shall only be valid upon execution of a written instrument in form and substance acceptable to the Committee in its sole discretion evidencing such transfer and the transferee’s acceptance thereof signed by the Participant and the transferee, and provided, further, that the Option may not be subsequently transferred other than by will or by the laws of descent and distribution or to another Permitted Transferee (as permitted by the Committee in its sole discretion) in accordance with the terms of the Plan and this Agreement, and shall remain subject to the terms of the Plan and this Agreement.  Any attempt to sell, exchange, transfer, assign, pledge, encumber or otherwise dispose of or hypothecate in any way the Option, or the levy of any execution, attachment or similar legal process upon the Option, contrary to the terms and provisions of this Agreement and/or the Plan shall be null and void and without legal force or effect.

8.             Withholding of Tax.  As a condition to exercising the Option, the Participant must remit to the Company an amount sufficient to satisfy any federal, state, local and foreign taxes of any kind (including, but not limited to, the Participant’s FICA and SDI obligations) which the Company, in its sole discretion, deems necessary to be withheld or remitted to comply with the Code and/or any other applicable law, rule or regulation with respect to the Option.  If the Participant fails to do so this Option shall not be deemed to have been exercised and the Company may refuse to issue or transfer any Shares otherwise required to be issued pursuant to this Agreement.

9.             Entire Agreement; Amendment.  This Agreement, together with the Plan and the Employment Agreement, contains the entire agreement between the parties hereto with respect to the subject matter contained herein, and supersedes all prior agreements or prior understandings, whether written or oral, between the parties relating to such subject matter.  The Committee shall have the right, in its sole discretion, to modify or amend this Agreement from time to time in accordance with and as provided in the Plan.  This Agreement may also be modified or amended by a writing signed by both the Company and the Participant.  The Company shall give written notice to the Participant of any such modification or amendment of this Agreement as soon as practicable after the adoption thereof.

11.           No Right to Employment.  Any questions as to whether and when there has been a Termination and the cause of such Termination shall be determined in the sole discretion of the Committee.  Nothing in this Agreement shall interfere with or limit in any way the right of the Company, its Subsidiaries or its Affiliates to terminate the Participant’s employment or service at any time, for any reason and with or without Cause.

12.           Transfer of Personal Data.  The Participant authorizes, agrees and unambiguously consents to the transmission by the Company (or any Subsidiary) of any personal data information related to the Option awarded under this Agreement for legitimate business purposes (including, without limitation, the administration of the Plan).  This authorization and consent is freely given by the Participant.

13.           Compliance with Laws.  The issuance of the Option (and the Option Shares upon exercise of the Option) pursuant to this Agreement shall be subject to, and shall comply with, any applicable requirements of any foreign and U.S. federal and state securities laws, rules and regulations (including, without limitation, the provisions of the Securities Act of 1933, as amended, the Exchange Act and in each case any respective rules and regulations promulgated thereunder) and any other law, rule, regulation or exchange requirement applicable
