THIS RESTRICTED STOCK UNIT 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 Project 350 Performance Award granted under 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 to grant Restricted Stock Units (“RSUs”) to the Participant;

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.

2.                                       Grant of Restricted Stock Unit Award.  The Company hereby grants to the Participant in accordance with the Project 350 Performance Award, as of the Grant Date specified above, the number of RSUs specified above.  Each RSU corresponds to one share of Company Stock.  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, and no adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of the shares of Company Stock underlying the RSUs, except as otherwise specifically provided for in the Plan or this Agreement.  By accepting this Award, the Participant agrees that the Company and its Affiliates by grant of the RSUs subject to this Award and by fulfillment of the terms of this Agreement will fully discharge any and all obligations or commitments to grant equity awards to the Participant pursuant to the Project 350 Performance Award, including, without limitation, any such obligations or commitments set forth in any employment agreement.

3.                                       Vesting.

(a)                                  Subject to the provisions of Sections 3(b) through 3(e) hereof, the RSUs subject to this Award shall vest in accordance with the following two vesting conditions:

·                                          2012 EBITDA.  The Company’s adjusted EBITDA for the calendar year ending December 31, 2012 must be at least $321.75 million (“2012 Target Adjusted EBITDA”).  If 2012 Target Adjusted EBITDA is not achieved for 2012, 50% of the RSUs subject to this Award will be immediately forfeited.

·                                          Time Vesting.  The outstanding RSUs subject to this Award (i.e., determined after any forfeiture due to the failure to achieve the 2012 Target Adjusted EBITDA) will vest on completion of the Company’s 2012 audit  (“2012 Audit Completion”) if the Participant is then employed by the Company or its Subsidiaries.

(b)                                 Termination of Employment without Cause or for Good Reason.  In the event the Participant’s employment with the Company and its Subsidiaries is terminated by the Company without Cause or by the Participant for Good Reason prior to the 2012 Audit Completion, the Participant will vest in 75% of the RSUs subject to this Award that would otherwise have vested upon 2012 Audit Completion (i.e., assuming the 2012 Target Adjusted EBITDA is achieved, the Participant will vest in 75% of the total RSUs subject to this Award; assuming the 2012 Target Adjusted EBITDA is not achieved, the Participant will vest in 37.5% (75% x 50%) of the RSUs subject to this Award).

(c)                                  Termination due to Death or Disability.  If the Participant’s employment with the Company and its Subsidiaries is terminated prior to the 2012 Audit Completion due to the Participant’s death or Disability, the Participant will vest  in 100% of the RSUs subject to this Award  that would otherwise have vested upon 2012 Audit Completion (i.e., assuming the 2012 Target Adjusted EBITDA is achieved, the Participant will vest in 100% of the total RSUs subject to this Award; assuming the 2012 Target Adjusted EBITDA is not achieved, the Participant will vest in 50% of the RSUs subject to this Award).

(d)                                 Change in Control.  If the Participant’s employment is terminated by the Company and its Subsidiaries without Cause or by the Participant for Good Reason before and with the cooperation of the acquiror or merger partner in a Change in Control or in anticipation of a Change in Control during the twelve (12) month period following a Change in Control, the Participant will vest in 100% of the RSUs subject to this Award that would otherwise have vested upon 2012 Audit Completion (i.e., assuming the 2012 Target Adjusted EBITDA is achieved, the Participant will vest in 100% of the total RSUs subject to this Award; assuming the 2012 Target Adjusted EBITDA is not achieved, the Participant will vest in 50% of the RSUs subject to this Award).

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

(f)                                    Waiver of Accelerated Vesting.  Notwithstanding anything set forth in any agreement between the Participant and the Company and/or an Affiliate to the contrary, including, without limitation, any employment agreement between the Participant and the Company and/or an Affiliate effective as of the date hereof, for purposes of this Agreement, the accelerated vesting provisions set forth in Sections 3(b), 3(c), 3(d), and 3(e) hereof shall be the exclusive provisions that shall accelerate the vesting of the RSUs granted hereunder and the Participant hereby waives any provision set forth in any agreement between the Participant and the Company and/or an Affiliate that would otherwise accelerated the vesting of the RSUs granted hereunder.

(g)                                 Forfeiture.  Subject to Sections 3(b), 3(c) and 3(d) and the Committee’s discretion to accelerate vesting hereunder, all unvested RSUs shall be immediately forfeited upon the Participant’s termination of employment for any reason.

4.                                       Delivery of Shares.

(a)                                  General.  Subject to the provisions of Sections 4(b) and 4(c) hereof, within thirty (30) days following the vesting of the RSUs, the Participant shall receive the number of shares of Company Stock that correspond to the number of RSUs that have become vested on the applicable vesting date.

(b)                                 Blackout Periods.  If the Participant is subject to any Company “blackout” policy or other trading restriction imposed by the Company on the date such distribution would otherwise be made pursuant to Section 4(a) hereof, such distribution shall be instead made on the earlier of (i) the date that the Participant is not subject to any such policy or restriction and (ii) the later of (A) the end of the calendar year in which such distribution would otherwise have been made and (B) a date that is immediately prior to the expiration of two and one-half months following the date such distribution would otherwise have been made hereunder.

(c)                                  Deferrals.  If permitted by the Company, the Participant may elect, subject to the terms and conditions of the Plan and any other applicable written plan or procedure adopted by the Company from time to time for

purposes of such election, to defer the distribution of all or any portion of the shares of Company Stock that would otherwise be distributed to the Participant hereunder (the “Deferred Shares”), consistent with the requirements of Section 409A of the Code.  Upon the vesting of RSUs that have been so deferred, the applicable number of Deferred Shares shall be credited to a bookkeeping account established on the Participant’s behalf (the “Account”).  Subject to Section 5 hereof, the number of shares of Company Stock equal to the number of Deferred Shares credited to the Participant’s Account shall be distributed to the Participant in accordance with the terms and conditions of the Plan and the other applicable written plans or procedures of the Company, consistent with the requirements of Section 409A of the Code.

5.                                       Dividends; Rights as Stockholder.  Cash dividends on shares of Company Stock issuable hereunder shall be credited to a dividend book entry account on behalf of the Participant with respect to each RSU granted to the Participant, provided that such cash dividends shall not be deemed to be reinvested in shares of Company Stock and shall be held uninvested and without interest and paid in cash at the same time that the shares of Company Stock underlying the RSUs are delivered to the Participant in accordance with the provisions hereof (as to any shares of stock delivered).  Stock dividends on shares of Company Stock shall be credited to a dividend book entry account on behalf of the Participant with respect to each RSU granted to the Participant, provided that such stock dividends shall be paid in shares of Company Stock at the same time that the shares of Company Stock underlying the RSUs are delivered to the Participant in accordance with the provisions hereof (as to any shares of stock delivered).  Except as otherwise provided herein, the Participant shall have no rights as a stockholder with respect to any shares of Company Stock covered by any RSU unless and until the Participant has become the holder of record of such shares.

6.                                       Non-Transferability.  No portion of the RSUs may be sold, assigned, transferred, encumbered, hypothecated or pledged by the Participant, other than to the Company as a result of forfeiture of the RSUs as provided herein, unless and until payment is made in respect of vested RSUs in accordance with the provisions hereof and the Participant has become the holder of record of the vested shares of Company Stock issuable hereunder.

7.                                       Governing Law.  All questions concerning the construction, validity and interpretation of this Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the choice of law principles thereof.

8.                                       Withholding of Tax.  As a condition to receiving the shares of Company Stock hereunder, 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 RSUs and, if the Participant fails to do so, the Company may refuse to issue or transfer any shares of Company Stock otherwise required to be issued pursuant to this Agreement.

9.                                       Legend.  The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of Company Stock issued pursuant to this Agreement.  The Participant shall, at the request of the Company, promptly present to the Company any and all certificates representing shares of Company Stock acquired pursuant to this Agreement in the possession of the Participant in order to carry out the provisions of this Section 9.
