This Transition and Retirement Agreement (the “Agreement”), dated as of February 20, 2020 is entered into by and between Six Flags Entertainment Corporation, a Delaware corporation (the “Company”) and Marshall Barber (the “Executive”).

W I T N E S S E T H: 

WHEREAS, the Company and Executive have entered into an Employment Agreement, dated as of February 18, 2016 (the “Employment Agreement”) pursuant to which the Executive currently serves as Executive Vice President and Chief Financial Officer of the Company.

WHEREAS, the Company and the Executive have agreed that the term of the Employment Agreement will terminate on the terms and at the time set forth in this Agreement and the Company and the Executive desire to set forth herein their mutual agreement with respect to Executive’s subsequent employment as an Advisor (“Transition”) and retirement from the Company on August 31, 2020 (“Retirement”) on the terms set forth in this Agreement.

 NOW, THEREFORE, in consideration of the mutual covenants set forth in this Agreement, it is hereby agreed as follows:

 1.Effective Date and Terms.  Executive’s employment by the Company pursuant to this Agreement shall commence (and employment by the Company pursuant to the Employment Agreement shall end except as otherwise specifically set forth in this Agreement) on the date of his Transition (“Transition Date”).  Unless specifically agreed to otherwise in writing by the Company and the Executive, the Transition Date shall be the second business day following the Company’s filing with the Securities and Exchange Commission the Company’s Annual Report on Form 10-K for the 2019 calendar year.  Terms not otherwise defined in this Agreement shall have the meaning set forth in the Employment Agreement.

 2.Position, Duties, Location and Support.

(a)Position and Duties.   Executive shall serve as an Advisor reporting to the Chief Executive Officer of the Company from the Transition Date through August 31, 2020 or such earlier termination of employment as provided in Section 4 of this Agreement (the “Transition Term”).   During the Transition Term, Executive shall perform the services reasonably requested by the Board, the Chief Executive Officer or Senior Leadership Team such as in connection with the transition of his duties and historical knowledge of events, financial matters, mergers and acquisitions, Board matters and outstanding litigation.  

(b)Attention and Time.   It is expected that Executive’s duties during the Transition Term will be of an advisory or transitional nature.  Executive shall use his reasonable best efforts to carry out such duties faithfully and efficiently.  During the Transition Term, it shall not be a violation of this Agreement for Executive to (i) serve on industry, trade, civic or charitable boards or committees; (ii) deliver lectures or fulfill speaking engagements; or (iii) manage personal investments, as long as such activities do not materially interfere with the performance of Executive’s duties and responsibilities as described herein.  Executive shall be permitted to serve on for-profit corporate boards of directors if approved in advance by the Board, which approval shall not be unreasonably withheld or delayed.  Notwithstanding the foregoing, Executive shall use Executive’s best efforts to resign from any

outside positions consistent with Executive’s obligations with respect to such position if the Board determines in good faith that such activities interfere in any material respect with the performance of Executive’s duties and responsibilities for the Company.    

 (c)Location.   Executive’s principal place of employment shall be located at the Company’s offices in Grand Prairie, Texas unless the Chief Executive Officer provides that Executive can provide services under this Agreement from outside the Company’s offices. Executive may be required to travel to and render services at other Company locations, as may reasonably be required by Executive’s duties hereunder. 

3.Compensation.  Provided Executive abides by the terms of this Agreement and remains employed by the Company, and in return for Executive’s promises in this Agreement, the Company agrees to the following:

(a)Base Salary.   During the Transition Term, Executive shall receive a base salary at a weekly rate of $10,913.46 per week.

 (b) Benefits.  During the Transition Term, Executive shall be entitled to participate in or receive benefits under employee benefit programs of the Company (including life, health and disability programs) that are made available generally to employees of the Company to the extent that Executive complies with the conditions attendant with coverage under such plans or arrangements.  Executive shall be expected to take his vacation prior to the end of the Transition Term.  Nothing contained herein shall be construed to prevent the Company from modifying or terminating any plan or arrangement (excluding, as it relates to Executive, expense reimbursements described in Section 3(c)).

 (c)Expenses.  The Company shall promptly reimburse Executive in accordance with applicable Company policy for all reasonable expenses that Executive incurs during Executive’s employment with the Company in carrying out Executive’s duties under this Agreement. 

(d)Value for Release.  Executive agrees and acknowledges that the foregoing payments and benefits are of significant value to Executive and represents full and complete consideration for the release Executive is giving the Company in Section 11 of this Agreement.  

4.Termination of Employment. 

(a)Retirement.  In connection with Executive’s Retirement, Executive shall be entitled to the Accrued Amounts and Executive shall have no further right or entitlement under this Agreement or the Employment Agreement to payments arising from such termination of employment.  All stock options that are not vested at Executive’s Retirement shall be forfeited upon Executive’s Retirement.

(b) Termination Other Than Retirement - By Company without Cause, Death or Disability.  Executive’s employment shall terminate automatically upon his death or Disability and the Company may terminate Executive’s employment with or without Cause.   Upon a termination of Executive’s employment due to Executive’s death or Disability or by the Company without Cause prior to August 31, 2020, Executive (or his estate) shall be entitled to the Accrued Amounts and, to the extent applicable, subject to Executive’s compliance with Sections 5, 6 and 7, payment through August 31, 2020 of Base Salary as specified in Section 3(a) of this Agreement as though Executive had remained employed through August 31, 2020.   Executive shall have no further right or entitlement under this Agreement or the Employment Agreement to payments arising from such termination of employment. 

All stock options that are not vested by their terms upon Executive’s termination of employment shall be forfeited upon Executive’s termination of employment.

(c) Termination Other Than Retirement - By Company for Cause or by Executive .  Executive’s employment shall terminate automatically upon his death or Disability.   The Company may terminate Executive’s employment for Cause and the Executive may terminate Executive’s employment for any reason and Executive would be entitled to Executive’s Accrued Amounts and Executive shall have no further right or entitlement under this Agreement or the Employment Agreement to payments arising from such termination of his employment by the Company for Cause or by Executive for any reason. 

(d)Release.  As a condition to receiving the payments set forth in Section 4(b) with respect to termination of employment by the Company without Cause or termination upon Disability, Executive shall be required, within 60 days of Executive’s Retirement or other termination of employment, to execute, deliver and not revoke (with any applicable revocation period having expired) a general release of claims in a form attached hereto as Exhibit A.  To the extent required by Section 20, any payments that would otherwise have been made during such 60-day period shall not be made and shall be accumulated and paid in a single lump sum on the expiration of such 60-day period.

(e)Full Discharge.  The amounts payable to Executive under this Section following termination of Executive’s employment shall be in full and complete satisfaction of Executive’s rights under this Agreement and the Employment Agreement and any other claims he may have in respect of his employment by the Company or any of its subsidiaries, and Executive acknowledges that such amounts are fair and reasonable, and his sole and exclusive remedy, in lieu of all other remedies at law or in equity, with respect to the termination of his employment hereunder or breach of this Agreement.  Nothing contained in this subsection shall serve as a bar to any claim that would not have been released if Executive executed the release attached as Exhibit A upon Executive’s termination of employment with the Company, whether or not such release is required to be executed in connection with such termination. 

(f)Other Positions. Executive shall immediately resign, and shall be deemed to have immediately resigned without the requirement of any additional action, from any and all positions Executive holds with the Company and its Affiliates on Executive’s Transition Date, other than as an Advisor pursuant to Section 2(a) of this Agreement.     

(g)Breach of Payment Obligation.  If the Company fails (other than pursuant to Section 19) to pay any amount due to Executive (or Executive’s estate) pursuant to this Section 4 as a result of Executive’s termination of employment within the fifteen (15) day period following written notice by Executive (it being understood and agreed that such notice may not be given until any such material payment has not been paid for at least 15 days following its scheduled payment date), the restrictions imposed by Section 7(a)(i) and (ii) shall immediately terminate.

5.Section 5  Confidentiality of Trade Secrets and Business Information of the Employment Agreement shall continue in effect.

 6.Return of Information.  Executive agrees that upon Retirement or any other termination of Executive’s employment with the Company, Executive shall deliver to the Company (at the Company’s expense), any and all notes, files, memoranda, papers and, in general, any and all physical (including electronic) matter containing Confidential Information that are in Executive’s possession or under Executive’s control, except as otherwise consented in writing by the Company at the time of such

termination.  The foregoing shall not prevent Executive from retaining copies of personal diaries, personal notes, personal address books, personal calendars, and any other personal information (including, without limitation, information relating to Executive’s compensation), but only to the extent such copies do not contain any Confidential Information other than that which relates directly to Executive, including Executive’s compensation. 

7.Noncompetition, Noninterference, Nondisparagement and Cooperation.

(a)General.  In consideration for the compensation payable to Executive under this Agreement and the Employment Agreement, Executive agrees that Executive shall not, other than in carrying out Executive’s duties thereunder, directly or indirectly, do any of the following (i) during Executive’s employment with the Company and its Subsidiaries and for a period of one (1) year after any termination of such employment, render services in any capacity (including as an employee, director, member, consultant, partner, investor or independent contractor) to a Competitor, (ii) during Executive’s employment with the Company and its Subsidiaries and for a period of one (1) year after any termination of such employment, attempt to, or assist any other person in attempting to, employ, engage, retain or partner with, any person who is then, or at any time during the ninety (90) day-period prior thereto was, a director, officer or other executive of the Company or a Subsidiary, or encourage any such person or any consultant, agent or independent contractor of the Company or any Subsidiary to terminate or adversely alter or modify such relationship with the Company or any Subsidiary, provided that this section (ii) shall not be violated by general advertising, general internet postings or other general solicitation in the ordinary course not specifically targeted at such persons, nor (iii) during Executive’s employment with the Company and its Subsidiaries and for a period of one (1) year after any termination of employment, solicit any then current customer (excluding any patrons of the Company’s amusement parks) or business partner of the Company or any Subsidiary to terminate, alter or modify its relationship with the Company or the Subsidiary or to interfere with the Company’s or any Subsidiary’s relationships with any of its customers or business partners.  During Executive’s employment with the Company and for one (1) year thereafter, Executive agrees not to make any public statement that is intended to or would reasonably be expected to disparage the Company, its Affiliates or its or their directors, officers, employees, businesses or products other than as required in the good faith discharge of his duties hereunder.  During the Executive’s employment with the Company and for one (1) year thereafter, the Company (including directors and officers of the Company in their capacity as such) agrees that it shall not make any public statement that is intended to or would reasonably be expected to disparage Executive.  At the request of Executive, the Company shall direct its directors and officers to not make any statements that would violate this Section 7(a) if they were made by the Company and shall use its commercially reasonable efforts to enforce such direction.  Notwithstanding the foregoing, nothing in this Section shall prevent any person from (A) responding publicly to any incorrect, disparaging or derogatory public statement made by or on behalf of the other party to the extent reasonably necessary to correct or refute such public statement or (B) making any truthful statement to the extent required by law.

(b)Cooperation.  Executive agrees to cooperate, in a reasonable manner and at the expense of the Company, with the Company and its attorneys, both during and after the termination of Executive’s employment, in connection with any litigation or other proceeding arising out of or relating to matters in which Executive was involved prior to the termination of Executive’s employment so long as such cooperation does not materially interfere with Executive’s employment or consulting.  In the event that such cooperation is required after six months after the end of the Transition Term, the Company shall pay the Executive at the rate of $4,500 per day and out-of-pocket expenses approved in advance by the Company after presentation by the Executive of reasonable documentation related thereto.

(c)Definition.  For purposes of this Agreement, “Competitor” shall mean any business or enterprise in the theme park business, which shall include, without limitation, amusement and water parks.  Notwithstanding the foregoing, Executive’s provision of services to an Affiliate or unit of a Competitor that is not directly engaged in the theme park business shall not be a violation of the restrictions of this Section 7 so long as Executive does not provide material services in respect of the theme park business and does not have material direct or indirect managerial or oversight responsibility or authority for the theme park business.  Nothing contained herein shall prevent Executive from acquiring, solely as an investment, any publicly-traded securities of any person so long as Executive remains a passive investor in such person and does not own more than one percent (1%) of the outstanding securities thereof.

8.Enforcement.  Executive acknowledges and agrees that:  (i) the purpose of the covenants set forth in Sections 5 through 7 above (the “Restrictive Covenants”) is to protect the goodwill, trade secrets and other confidential information of the Company; (ii) because of the nature of the business in which the Company is engaged and because of the nature of the Confidential Information to which Executive has access, it would be impractical and excessively difficult to determine the actual damages of the Company in the event Executive breached any such covenants; and (iii) remedies at law (such as monetary damages) for any breach of Executive’s obligations under the Restrictive Covenants would be inadequate.  Executive therefore agrees and consents that if Executive commits any breach of a Restrictive Covenant, the Company shall have the right (in addition to, and not in lieu of, any other right or remedy that may be available to it) to temporary and permanent injunctive relief from a court of competent jurisdiction, without posting any bond or other security and without the necessity of proof of actual damage.  If any portion of the Restrictive Covenants is hereafter determined to be invalid or unenforceable in any respect, such determination shall not affect the remainder thereof, which shall be given the maximum effect possible and shall be fully enforced, without regard to the invalid portions.  In particular, without limiting the generality of the foregoing, if the covenants set forth in Section 7 are found by a court or an arbitrator to be unreasonable, Executive and the Company agree that the maximum period, scope or geographical area that is found to be reasonable shall be substituted for the stated period, scope or area, and that the court or arbitrator shall revise the restrictions contained herein to cover the maximum period, scope and area permitted by law.  If any of the Restrictive Covenants are determined to be wholly or partially unenforceable in any jurisdiction, such determination shall not be a bar to or in any way diminish the Company’s right to enforce any such covenant in any other jurisdiction.

 9.Indemnification.

(a)The Company agrees that if Executive is made a party to, is threatened to be made a party to, receives any legal process in, or receives any discovery request or request for information in connection with, any action, suit or proceeding, whether civil, criminal, administrative or investigative, excluding any action instituted by Executive, any action related to any actual violation of Section 16 of the Exchange Act by Executive or  any action brought by the Company  for compensation or damages related to Executive’s breach of this Agreement (a “Proceeding”), by reason of the fact that Executive was a director, officer, employee, consultant or agent of the Company, or was serving at the request of, or on behalf of, the Company as a director, officer, member, employee, consultant or agent of another corporation, limited liability corporation, partnership, joint venture, trust or other entity, including service with respect to employee benefit plans, whether or not the basis of such Proceeding is Executive’s alleged action in an official capacity while serving as a director, officer, member, employee, consultant or agent of the Company or other entity, Executive shall be indemnified and held harmless by the Company to the fullest extent permitted or authorized by the Company’s certificate of incorporation or by-laws or,

if greater, by applicable law, against any and all costs, expenses, liabilities and losses (including, without limitation, attorneys’ fees reasonably incurred, judgments, fines, taxes or penalties and amounts paid or to be paid in settlement and any reasonable cost and fees incurred in enforcing Executive’s rights to indemnification or contribution) incurred or suffered by Executive in connection therewith, and such indemnification shall continue as to Executive even though Executive has ceased to be a director, officer, member, employee, consultant or agent of the Company or other entity and shall inure to the benefit of Executive’s heirs, executors and administrators.  The Company shall reimburse Executive for all costs and expenses (including, without limitation, reasonable attorneys’ fees) incurred by Executive in connection with any Proceeding within twenty (20) business days after receipt by the Company of a written request for such reimbursement and appropriate documentation associated with these expenses.  Such request shall include an undertaking by Executive to repay the amount of such advance if it shall ultimately be determined that Executive is not entitled to be indemnified against such costs and expenses; provided that the amount of such obligation to repay shall be limited to the after-tax amount of any such advance except to the extent Executive is able to offset such taxes incurred on the advance by the tax benefit, if any, attributable to a deduction for repayment.

(b)Neither the failure of the Company (including its board, independent legal counsel or stockholders) to have made a determination prior to the commencement of any proceeding concerning payment of amounts claimed by Executive under Section 9(a) above that indemnification of Executive is proper because Executive has met the applicable standard of conduct, nor a determination by the Company (including its board, independent legal counsel or stockholders) that Executive has not met such applicable standard of conduct, shall create a presumption or inference that Executive has not met the applicable standard of conduct.

 (c)The Company agrees to continue and maintain a directors’ and officers’ liability insurance policy covering Executive at a level, and on terms and conditions, no less favorable to Executive than the coverage the Company provides other similarly-situated executives for six years after Executive’s termination of employment with the Company or such longer statute of limitation period.

(d)Nothing in this Section 9 shall be construed as reducing or waiving any right to indemnification, or advancement of expenses, Executive would otherwise have under the Company’s certificate of incorporation or by-laws or under applicable law.

10.Arbitration.  Subject to Section 8, in the event that any dispute arises between the Company and Executive regarding or relating to this Agreement and/or any aspect of Executive’s employment relationship with the Company, the parties consent to resolve such dispute through mandatory arbitration under the Commercial Rules of the American Arbitration Association (“AAA”), before a single arbitrator in Dallas, Texas.  The parties hereby consent to the entry of judgment upon award rendered by the arbitrator in any court of competent jurisdiction.  Notwithstanding the foregoing, however, should adequate grounds exist for seeking immediate injunctive or immediate equitable relief, any party may seek and obtain such relief.  The parties hereby consent to the exclusive jurisdiction of the state and Federal courts of or in the State of Texas for purposes of seeking such injunctive or equitable relief as set forth above.  Out-of-pocket costs and expense reasonably incurred by Executive in connection with such arbitration (including attorneys’ fees) shall be paid by the Company with respect to each claim on which the arbitrator determines Executive prevails.

11.General Release.

(a)In exchange for Executive’s waiver of claims against the Released Persons (as defined below) and compliance with the other terms and conditions of this Agreement, upon the

Transition Date, the Company agrees to provide Executive with the payments and benefits as set forth in Section 3 in accordance with the terms and conditions of this Agreement.

(b)In consideration for the payments and benefits to be provided to Executive pursuant to Section 3 above, Executive, for himself and for his heirs, executors, administrators, trustees, legal representatives and assigns (hereinafter referred to collectively as “Releasors”), forever release and discharge the Company and its subsidiaries, divisions, affiliates and related business entities, successors and assigns, and any of its or their respective directors, officers, fiduciaries, agents, trustees, administrators, employees and assigns (in each case, in their capacity as such) (collectively the “Released Persons”) from any and all claims, suits, demands, causes of action, covenants, obligations, debts, costs, expenses, fees and liabilities of any kind whatsoever in law or equity, by statute or otherwise, whether known or unknown, vested or contingent, suspected or unsuspected and whether or not concealed or hidden (collectively, the “Claims”), which Executive has had, now has, or may have against any of the Released Persons by reason of any act, omission, transaction, practice, plan, policy, procedure, conduct, occurrence, or other matter arising up to and including the date on which Executive signs this Agreement, except as provided in subsection (d) below.

(c)Without limiting the generality of the foregoing, this Agreement is intended to and shall release the Released Persons from any and all such claims, whether known or unknown, which Executive has had, now has, or may have against the Released Persons arising out of Executive’s employment or termination thereof, including, but not limited to: (i) any claim under the Age Discrimination in Employment Act, Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act, the Employee Retirement Income Security Act of 1974 (excluding claims for accrued, vested benefits under any employee benefit or pension plan of the Released Persons subject to the terms and conditions of such plan and applicable law), the Family and Medical Leave Act, the Worker Adjustment and Retraining Notification Act of 1988, or the Fair Labor Standards Act of 1938, in each case as amended; (ii) any other claim whether based on federal, state, or local law (statutory or decisional), rule, regulation or ordinance, including, but not limited to, breach of contract (express or implied), wrongful discharge, detrimental reliance, defamation, emotional distress or compensatory or punitive damages; and (iii) any claim for attorneys’ fees, costs, disbursements and/or the like.

(d)Notwithstanding the foregoing, nothing in this Agreement shall be a waiver of claims: (1) that arise after the date on which Executive signs this Agreement; (2) regarding rights of indemnification and receipt of legal fees and expenses to which Executive is entitled under Section 9 of this Agreement, the Company’s or a subsidiary of the Company’s Certificate of Incorporation or Bylaws (or similar instrument), pursuant to any separate writing between Executive and the Company or any subsidiary of the Company or pursuant to applicable law; or (3) relating to any claims for accrued, vested benefits under any employee benefit plan or retirement plan of the Released Persons subject to the terms and conditions of such plan and applicable law (excluding any severance or termination pay plan, program or arrangement, claims to which are specifically waived hereunder or any unvested equity awards, claims to which are specifically waived hereunder).

(f)This Agreement is not intended, and shall not be construed, as an admission that any of the Released Persons has violated any federal, state or local law (statutory or decisional), ordinance or regulation, breached any contract or committed any wrong whatsoever against Executive.

(g)Should any provision of this Agreement require interpretation or construction, it is agreed by the parties that the entity interpreting or constructing this Agreement shall not apply a presumption against one party by reason of the rule of construction that a document is to be construed more strictly against the party who prepared the document.

 20.Section 409A.  This Agreement is intended to satisfy the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”) with respect to amounts, if any, subject thereto and shall be interpreted and construed and shall be performed by the parties consistent with such intent.  To the extent Executive would otherwise be entitled to any payment under this Agreement, or any plan or arrangement of the Company or its Affiliates, that constitutes a “deferral of compensation” subject to Section 409A and that if paid during the six (6) months beginning on the Executive’s separation from service would be subject to the Section 409A additional tax because Executive is a “specified employee” (within the meaning of Section 409A and as determined by the Company), the payment will be paid to Executive on the earlier of the six (6) month anniversary of his separation from service or death.  To the extent Executive would otherwise be entitled to any benefit (other than a payment) during the six (6) months beginning on Executive’s separation from service that would be subject to the Section 409A additional tax, the benefit will be delayed and will begin being provided on the earlier of the first day following the six (6) month anniversary of Executive’s separation from service or death.  Any payment or benefit due upon a termination of employment that represents a “deferral of compensation” within the meaning of Section 409A shall be paid or provided only upon a “separation from service” as defined in Treasury Regulation § 1.409A-1(h).  Each payment made under this Agreement shall be deemed to be a separate payment for purposes of Section 409A.  Amounts payable under this Agreement shall be deemed not to be a “deferral of compensation” subject to Section 409A to the extent provided in the exceptions in Treasury Regulation §§ 1.409A-1(b)(4) (“Short-Term Deferrals”) and (b)(9) (“Separation Pay Plans,” including the exception under subparagraph (iii)) and other applicable provisions of Treasury Regulation § 1.409A-1 through A-6.  Notwithstanding anything to the contrary in this Agreement or elsewhere, any payment or benefit under this Agreement or otherwise that is exempt from Section 409A pursuant to Treasury Regulation § 1.409A-1(b)(9)(v)(A) or (C) (relating to certain reimbursements and in-kind benefits) shall be paid or provided only to the extent that the expenses are not incurred, or the benefits are not provided, beyond the last day of the second calendar year following the calendar year in which Executive’s “separation from service” occurs; and provided further that such expenses are reimbursed no later than the last day of the third calendar year following the calendar year in which Executive’s “separation from service” occurs.  To the extent any expense reimbursement (including without limitation any reimbursement of interest or penalties related to taxes) or the provision of any in-kind benefit is determined to be subject to Section 409A (and not exempt pursuant to the prior sentence or otherwise), the amount of any such expenses eligible for reimbursement, or the provision of any in-kind benefit, in one calendar year shall not affect the expenses eligible for reimbursement in any other calendar year (except for any lifetime or other aggregate limitation applicable to medical expenses), in no event shall any expenses be reimbursed after the last day of the calendar year following the calendar year in which Executive incurred such expenses, and in no event shall any right to reimbursement or the provision of any in-kind benefit be subject to liquidation or exchange for another benefit.

 21.Headings.  The Section headings contained in this Agreement are for convenience only and in no manner shall be construed as part of this Agreement.

22.Entire Agreement.  This Agreement constitutes the entire agreement of the parties with respect to the subject matter hereof and shall supersede all prior agreements other than outstanding equity grants, whether written or oral, with respect thereto, including without limitation, the employment

agreement between the Company and Executive dated as of February 18, 2016  except to the extent such Employment Agreement is specifically incorporated into this Agreement.   In the event of any inconsistency between the terms of this Agreement and the terms of any other Company plan, policy, equity grant, arrangement or agreement with Executive, the provisions most favorable to Executive shall govern.

23.Duration of Terms.  The respective rights and obligations of the parties hereunder shall survive any termination of Executive’s employment to the extent necessary to give effect to such rights and obligations.

24.Counterparts.  This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

25.Certain Change in Control Payments.  Notwithstanding any provision of this Agreement to the contrary, if any payments or benefits Executive would receive from the Company under this Agreement or otherwise in connection with the Change in Control (the “Total Payments”) (a) constitute “parachute payments” within the meaning of Section 280G of the Code, and (b) but for this Section 25, would be subject to the excise tax imposed by Section 4999 of the Code, then Executive will be entitled to receive either (i) the full amount of the Total Payments or (ii) a portion of the Total Payments having a value equal to $1 less than three (3) times such individual’s “base amount” (as such term is defined in Section 280G(b)(3)(A) of the Code), whichever of (i) and (ii), after taking into account applicable federal, state, and local income taxes and the excise tax imposed by Section 4999 of the Code, results in the receipt by such employee on an after-tax basis, of the greatest portion of the Total Payments.  Any determination required under this Section 25 shall be made in writing by the accountant or tax counsel selected by the Executive.  If there is a reduction pursuant to this Section 25 of the Total Payments to be delivered to the applicable Executive and to the extent that an ordering of the reduction other than by the Executive is required by Section 20 or other tax requirements, the payment reduction contemplated by the preceding sentence shall be implemented by determining the “Parachute Payment Ratio” (as defined below) for each “parachute payment” and then reducing the “parachute payments” in order beginning with the “parachute payment” with the highest Parachute Payment Ratio.  For “parachute payments” with the same Parachute Payment Ratio, such “parachute payments” shall be reduced based on the time of payment of such “parachute payments,” with amounts having later payment dates being reduced first.  For “parachute payments” with the same Parachute Payment Ratio and the same time of payment, such “parachute payments” shall be reduced on a pro rata basis (but not below zero) prior to reducing “parachute payments” with a lower Parachute Payment Ratio.  For purposes hereof, the term “Parachute Payment Ratio” shall mean a fraction the numerator of which is the value of the applicable “parachute payment” for purposes of Section 280G of the Code and the denominator of which is the actual present value of such payment.

 IN WITNESS WHEREOF, Executive and the Company have caused this Agreement to be executed as of the date first above written.

instrument), pursuant to any separate writing between you and the Company or any subsidiary of the Company or pursuant to applicable law; or (4) relating to any claims for accrued, vested benefits under any employee benefit plan or retirement plan of the Released Persons subject to the terms and conditions of such plan and applicable law (excluding any severance or termination pay plan, program or arrangement, claims to which are specifically waived hereunder or any unvested equity awards, claims to which are specifically waived hereunder).
