4. Position and Duties. (a) During the Term, the Executive shall serve as the Chairman of the Board and Chief Executive Officer of the Company and shall have the authority, functions, duties, powers and responsibilities normally associated with such positions and as from time to time may be prescribed by the Board. The Executive agrees, subject to his election as such and without additional compensation, to serve during the Term in such additional offices of comparable stature and responsibility to which he may be elected from time to time in the Company’s Subsidiaries and to serve as a director and as a member of any committee of the Board and as a director of the Company’s Subsidiaries.

(b) During the Term and subject to the provisions of Section 4(c), (i) the Executive’s services shall be rendered on a full-time, exclusive basis, (ii) he will apply on a full-time basis all of his skill and experience to the performance of his duties in such employment, and shall report only to the Board, (iii) he shall have no other employment or outside business activities and (iv) unless the Executive otherwise consents, the headquarters for the performance of his services shall be the executive offices of the Company in the greater New York City area, subject to such reasonable travel as the performance of his duties in the business of the Company may require.

(c) During the Term, the Executive shall not, directly or indirectly, without the prior written consent of the Board, render any services to any person (other than the Company and its Subsidiaries and other persons in which the Company may have an interest), or acquire any interest of any type in any such other person that is in competition with the Company or any

of its Subsidiaries or in conflict with his full-time, exclusive position as a senior executive officer of the Company; provided, however, that the foregoing shall not be deemed to prohibit the Executive from (i) acquiring, solely as an investment, securities of any person which are registered under Section 12(b) or 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and which are publicly traded, so long as he is not part of any group required to make any filing under Section 13(d) of the Exchange Act in respect of such person and such securities do not constitute 2% or more of any class of outstanding securities of such person, (ii) acquiring, solely as an investment, any securities of any person (other than a person that has outstanding securities covered by the preceding clause (i)) so long as he remains a passive investor in such person and does not become part of any control group thereof and so long as such person is not, directly or indirectly, in competition with the Company or any of its Subsidiaries or (iii)(A) serving on the boards of directors of a reasonable number of other corporations (none of which are in competition with the Company or its Subsidiaries) or the boards of a reasonable number of trade associations and/or charitable organizations or, with the prior written consent of the Committee, to provide consulting services for any such corporation, trade association and/or charitable organization, (B) engaging in charitable activities and community affairs and (C) managing his personal investments and affairs, provided that the activities referred to in this clause (iii) do not in the aggregate interfere in any material respect with the proper performance of his duties and responsibilities as the Company’s Chairman of the Board and Chief Executive Officer. For purposes of the foregoing, a person shall be deemed to be in competition with the Company or any of its Subsidiaries if it (or its Subsidiaries or Affiliates) is then engaged in any line of business that is substantially the same as any line of business in which the Company or any of its Subsidiaries is engaged.

(d) The Company shall use its best efforts to cause the Executive to be a member of the Board throughout the Term and shall include him in the management slate for election as a director at every stockholders’ meeting at which his term as a director would otherwise expire.

5. Compensation. (a) Base Salary. The Company shall pay or cause to be paid to the Executive a base salary (the “Base Salary”) of (i) during the year ending December 31, 2004, $1,000,000 per annum, and (ii) during each succeeding calendar year (or portion thereof) during the Term an amount per annum equal to $50,000 plus the Base Salary in effect at the end of the immediately preceding calendar year. The Company may increase, but not decrease, the Base Salary at any time and from time to time during the Term. The Base Salary shall be payable in monthly or more frequent installments in accordance with the Company’s regular payroll practices for senior executives.

(b) Bonus. In addition to the Base Salary, the Executive shall be entitled to receive an annual cash bonus (the “Bonus”) in an amount equal to the sum of (a) .00778 multiplied by the Budgeted EBITDA for the applicable year plus (b) .02723 multiplied by the amount, if any, by which the Actual EBITDA for such year exceeded the Budgeted EBITDA for such year; provided, however, that if in any year, the Actual EBITDA is less than 95% of the amount of the Budgeted EBITDA for such year, the product obtained by clause (a) above shall be multiplied by the Applicable Percentage set forth on Exhibit A in determining the amount of the Bonus payable with respect to such year. The Bonus will be payable with respect to each of the

Company’s fiscal years ending December 31, 2004, December 31, 2005 and December 31, 2006 and, except as provided in Section 5(c), will be payable as follows: (i) 75% of the estimated Bonus will be paid to the Executive in the immediately succeeding January; and (ii) the remaining amount of the Bonus over the amount previously paid in January of that year will be paid to the Executive not later than 80 days after the end of the preceding year.

Within 75 days following the end of each applicable year during the Term, the independent public accountants of the Company shall deliver to the Committee a certificate setting forth the calculation of EBITDA for such year based on the Company’s audited financial statements for such year and, if applicable, an agreed upon procedure report on all adjustments to EBITDA required by clauses (i) and (ii) of the definition of Actual EBITDA and by the provisions of Section 5(c)(i). Within 80 days after the end of each such year, the Committee shall deliver to the Executive a notice, in reasonable detail, showing the calculation of Actual EBITDA for such year, the Bonus payable to the Executive under this Section 5(b) with respect to such year and the number of Restricted Shares with respect to which the Restriction Period has expired by virtue of such EBITDA pursuant to Section 5(c)(i) hereof.

(c) Deferred Compensation. The Executive by timely notice delivered to the Committee may elect to defer any portion of the Base Salary or Bonus with respect to any year on terms reasonably acceptable to the Company, provided such deferral does not result in the Company incurring any additional expense.

(d) Options. On January 2, 2004, the Company will grant to the Executive under the Company’s 2001 Stock Option and Incentive Plan (the “2001 Plan”) options (the “Initial Options”) to purchase 275,000 shares of the Company’s Common Stock, par value $.05 per share (the “Common Stock”). The Initial Options shall have a term of seven years, shall have an exercise price per share equal to the “fair market value” (as defined in the 2001 Plan) of a share of Common Stock on the date of grant; shall vest and become exercisable in four equal annual installments, commencing on January 2, 2005, if the Executive is employed by the Company or any Subsidiary on such vesting date, except as otherwise provided in Section 10 hereof, and shall have such other terms and conditions, not inconsistent with the foregoing or with any other provision of this Agreement, as are customarily contained in the grant letters under the 2001 Plan heretofore issued by the Company. On each of January 2, 2005, January 2, 2006 and December 31, 2006 the Company will grant to the Executive under the 2001 Plan options (the “Subsequent Options” and together with the Initial Options, the “Options”) to purchase 120,000 shares of Common Stock. The Subsequent Options shall have a term of seven years, shall have an exercise price per share equal to the fair market value (as defined in the 2001 Plan) of a share of Common Stock on the date of grant, shall vest and become exercisable in three equal annual installments, commencing on the date of grant, if the Executive is employed by the Company or any Subsidiary on such vesting date, except as otherwise provided in Section 10 hereof, and shall have such other terms and conditions, not inconsistent with the foregoing or with any other provision of this Agreement, as are customarily contained in grant letters under the 2001 Plan heretofore issued by the Company. In the event of a stock dividend, stock split, share combination, exchange of shares, recapitalization, merger, consolidation, reorganization, liquidation or other comparable changes or transactions of or by the Company, an appropriate

adjustment to the number of Common Stock into which the Options are exercisable shall be made to give proper effect to such event.

6. Employee Benefit Programs. During the Term, the Executive shall be entitled to participate in all employee pension and welfare benefit plans and programs made available to the Company’s senior level executives or its employees generally, as such plans or programs may be in effect from time to time, including without limitation, pension, savings and other retirement plans or programs, medical, dental, hospitalization, short-term and long-term disability and life insurance plans, and any other employee benefit plans or programs that may be sponsored by the Company from time to time, whether funded or unfunded.

7. Reimbursement of Expenses. During the Term, the Company shall pay or reimburse the Executive for all reasonable travel, entertainment and other business expenses actually incurred or paid by the Executive in the performance of his duties hereunder upon presentation of expense statements or vouchers or such other supporting information as the Company may reasonably require.

8. Vacations. In addition to customary paid holidays, the Executive shall be entitled to four (4) weeks of paid vacation during each year of the Term (and a pro rata portion thereof for any portion of the Term that is less than a full year). Any unused vacation days during any year shall not be carried forward to subsequent years, nor shall the Executive receive any additional compensation for such unused vacation days.

9. The Restricted Shares. (a) On January 2, 2004, and in consideration of services to be performed by the Executive hereunder, the Company will grant to the Executive, subject to the provisions of this Section 9, 250,000 shares (the “Initial Restricted Shares”) of the Company’s Common Stock. In addition, on each of January 2, 2005, January 2, 2006 and January 2, 2007, the Company shall grant to the Executive an additional 40,000 shares of Common Stock (the “Additional Restricted Shares” and, together with the Initial Restricted Shares, the “Restricted Shares”).

(b) During the Restriction Period (as defined below) relating to any Restricted Shares, such Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered by the Executive. Except as provided in this Section 9, the Executive, as the owner of Restricted Shares, shall have all the rights of a holder of Common Stock, including but not limited to the right to receive all cash dividends or distributions paid on and the right to vote such Restricted Shares until such date as such Restricted Shares shall have been forfeited pursuant to Section 9(g).

(c) The restrictions contained in this Section 9 on the rights of the Executive to sell, assign, transfer or encumber the Restricted Shares and on his ability to hold the certificates representing the Restricted Shares pursuant to Section 9(d) shall expire as follows:

(i) the restrictions on 41,667 (41,666 in the case of January 2, 2005 and January 2, 2006) Initial Restricted Shares shall expire on each of January 2, 2005, January 2, 2006, January 2, 2007, January 2, 2008, January 2, 2009 and January 2, 2010, if the Executive is

employed by the Company or any Subsidiary on such date, except as otherwise provided in Section 10 hereof. Notwithstanding the foregoing, if either (x) EBITDA for any fiscal year during the Term shall exceed 105% of EBITDA for the immediately preceding year or (y) the Committee so determined in its discretion based on non-EBITDA related performance of the Executive in such fiscal year, the Restriction Period (as defined below) with respect to an additional 41,667 Initial Restricted Shares shall expire either on (x) the date the independent public accountants of the Company deliver to the Committee the certificate referred to in Section 5(b) hereof or (y) the date the Committee makes such determination. In that event, the additional Initial Restricted Shares as to which the Restriction Period shall expire pursuant to the foregoing sentence shall be those Initial Restricted Shares, the Restriction Period of which would otherwise have expired on the latest applicable date pursuant to this Section 9(c)(i). In determining EBITDA for the purposes of this paragraph only for any applicable fiscal year and the prior fiscal year, the results of operations of any person or business which was the subject of an Acquisition since the beginning of such prior fiscal year shall be included in such determination on a pro forma basis as if such Acquisition had occurred (and all related costs and expenses were incurred) on the day immediately preceding the first day of such prior fiscal year and the results of operations of any person or business which was the subject of a Disposition since the beginning of such prior fiscal year shall be excluded in such determination on a pro forma basis as if such Disposition had occurred (and all related costs and expenses were incurred) on the day immediately preceding the first day of such prior fiscal year.

(ii) the restrictions on 13,333 (13,334 in the case of the first anniversary date) Subsequent Restricted Shares issued on any date hereunder shall expire on the date of issuance and the two succeeding anniversary dates of the date of issuance, if the Executive is employed by the Company or any Subsidiary on such date, except as otherwise provided in Section 10 hereof.

(iii) The period during which the restrictions set forth in this Section 9(c) as to the ownership, transfer and disposition by the Executive of any Restricted Shares shall be in effect shall be referred to herein as the “Restriction Period.”

(d) Each certificate representing Restricted Shares or Additional Restricted Shares shall be registered in the name of the Executive, be deposited by him with the Company together with a stock power endorsed in blank and bear the following, or a substantially similar, legend:

“The transferability of this Certificate and the Common Stock represented hereby is subject to the terms and conditions, including forfeiture, contained in the Employment Agreement, dated as of January 1, 2004, between the Company and Xxxxxx X. Xxxxx. A copy of the Employment Agreement is on file in the executive offices of Six Flags, Inc., 00000 Xxxxxxxxx Xxxxxxxxxx, Xxxxxxxx Xxxx, Xxxxxxxx 00000.”

(e) To the extent any Restricted Shares shall not have been registered under the Securities Act of 1933, as amended (the “Securities Act”), the Executive hereby represents

and warrants that he (i) is acquiring such Restricted Shares for his own account and not with a view to the sale or distribution thereof except in compliance with the Securities Act of 1933, as amended (the “Securities Act”) and applicable state securities laws and (ii) is an “accredited investor” as such term is defined in Regulation D under the Securities Act.

(f) After the Restriction Period relating to any Restricted Shares has expired, upon the written request of the Executive, or the Executive’s legal representative, permitted successor or heir, the Company shall deliver to the Executive, or such legal representative, permitted successor or heir, a certificate or certificates, without the legend referred to in Section 9(d), for the number of such Restricted Shares. Notwithstanding the foregoing, any certificate or certificates so delivered shall bear such legends as the Company may deem advisable to reflect restrictions which may be imposed by law, including, without limitation, the Securities Act or any state “blue sky” or other applicable securities laws.

(g) The Executive’s rights to any Restricted Shares shall be forfeited on the first date on which it can be determined that the Restriction Period with respect to such Restricted Shares is incapable of expiring pursuant to the provisions of Section 9(c). Any Restricted Shares with respect to which the Restriction Period has not expired shall be forfeited as of the last day thereof. Certificates representing any forfeited Restricted Shares shall be cancelled by the Company, and the Executive shall have no rights with respect to any such forfeited Shares.

(h) If the Company shall be consolidated or merged with another corporation, and such consolidation or merger is not a Change of Control, the Executive will deposit with the successor corporation the certificates for the stock or securities or the other property that the Executive is entitled to receive by reason of his ownership of Restricted Shares in a manner consistent with Section 9(d), and such stock, securities or other property shall become subject to the restrictions and requirements imposed by this Section 9, and the certificates therefor or other evidence thereof shall bear a legend similar in form and substance to the legend set forth in Section 9(d).

(i) In the event of a stock dividend, stock split, share combination, exchange of shares, recapitalization, merger, consolidation, reorganization, liquidation or other comparable changes or transactions of or by the Company, an appropriate adjustment to the number of Restricted Shares shall be made to give proper effect to such event.

10. Termination of Employment.

(ii) a Bonus for the year in which the Executive’s death occurs in an amount equal to the Bonus (if any) that would have been payable to the Executive with respect to such year had his death not occurred, multiplied (in the event such death occurs before June 30 of such year) by a fraction, the numerator of which shall be the number of days elapsed during such year prior to the date of the Executive’s death and the denominator of which shall be 181, payable as provided in Section 5(b);

If, within five days after such hearing, the Executive is furnished written notice that a majority of all then members of the Board (excluding the Executive) have confirmed that, in their judgment, grounds for Cause exist, his employment shall thereupon terminate for Cause.
