CHANGE IN CONTROL AGREEMENT

Exhibit 10.2

CHANGE IN CONTROL AGREEMENT

This CHANGE IN CONTROL AGREEMENT (the “Agreement”) is entered into on April 1, 2008 (the “Effective Date”) by and between Celanese Corporation (the “Company”) and Xxxxxx Beach Xxx (the “Executive”).

The Company considers it essential to xxxxxx the continued employment of key management personnel. The Board of Directors of the Company (the “Board”) believes that it is in the best interests of the Company and its stockholders to assure the Company will have the continued dedication of Executive, notwithstanding the possibility, threat or occurrence of a Change in Control. The Board believes it is imperative to diminish the inevitable distraction of Executive by virtue of the personal uncertainties and risks created by a pending or threatened Change in Control and to encourage Executive’s full attention and dedication to the Company currently and in the event of any threatened or pending Change in Control. The Company also requests, and the Executive desires to give the Company, certain assurances with regard to the protection of Confidential Information and Intellectual Property of the Company and its Affiliates.

i. “Confidential Information” shall mean any non-public, proprietary or confidential information, including without limitation trade secrets, know-how, research and development, software, databases, inventions, processes, formulae, technology, designs and other intellectual property, information concerning finances, investments, profits, pricing, costs, products, services, vendors, customers, clients, partners, investors, personnel, compensation, benefits, recruiting, training, advertising, sales, marketing, promotions, government and regulatory activities and approvals concerning the past, current or future business, activities and operations of the Company, its Affiliates and/or any third party that has disclosed or provided any of same to the Company or its Affiliates on a confidential basis. “Confidential Information” also includes any information designated as a trade secret or proprietary information by operation of law or otherwise, but shall not be limited by such designation. “Confidential Information” shall not include any information that is (i) generally known to the industry or the public other than as a result of Executive’s breach of this covenant; (ii) made legitimately available to Executive by a third party without breach of any confidentiality obligation; or (iii) required by law to be disclosed; provided that Executive shall give prompt written notice to the Company of such requirement, disclose no more information than is so required, and cooperate with any attempts by the Company to obtain a protective order or similar treatment.

l. “Good Reason” shall mean any of the following conditions which occurs without the consent of the Executive: (i) a material diminution in the Executive’s base salary or

n. “Person” shall mean any person, firm, partnership, joint venture, association, corporation or other business organization, entity or enterprise whatsoever.

o. “Restricted Period” shall be (i) one year from the Termination Date in the event of a Separation from Service that occurs during the Service Term (as defined hereinafter) other than in the case of an involuntary Separation from Service without Cause, (ii) in the case of an involuntary Separation from Service without Cause during the Service Term, an amount of time in whole months equal to the number of months’ salary the Company agrees to provide to Executive in severance, whether paid over time or in a lump sum; and (iii) two years from the Termination Date in the event of a Separation from Service following a Change In Control where Executive receives the Change In Control Payment (as defined hereinafter).

p. “Separation from Service” shall mean an event after which the Executive shall no longer provide services to the members of the Controlled Group, whether voluntarily or involuntarily as determined by the Committee (as hereafter defined) in accordance with Treas. Reg. §1.409A-1(h)(1). A Separation from Service shall occur when Executive has experienced a termination of employment from the members of the Controlled Group. Executive shall be considered to have experienced a termination of employment when the facts and circumstances indicate that the Executive and the Company reasonably anticipate that either (i) no further services will be performed for the members of the Controlled Group after a certain date, or (ii) that the level of bona fide services the Executive will perform for the members of the Controlled Group after such date (whether as an employee or as an independent contractor) will permanently decrease to no more than 20% of the average level of bona fide services performed by such Executive (whether as an employee or an independent contractor) over the immediately preceding 36-month period (or the full period of services to the members of the Controlled Group if the Executive has been providing services to the members of the Controlled Group less than 36 months). If Executive is on military leave, sick leave, or other bona fide leave of absence, the employment relationship between the Executive and the members of the Controlled Group shall be treated as continuing intact, provided that the period of such leave does not

exceed 6 months, or if longer, so long as the Executive retains a right to reemployment with the members of the Controlled Group under an applicable statute or by contract. If the period of a military leave, sick leave, or other bona fide leave of absence exceeds 6 months and the Executive does not retain a right to reemployment under an applicable statute or by contract, the employment relationship shall be considered to be terminated for purposes of this Agreement as of the first day immediately following the end of such 6-month period. In applying the provisions of this paragraph, a leave of absence shall be considered a bona fide leave of absence only if there is a reasonable expectation that the Executive will return to perform services for any members of the Controlled Group.

Notwithstanding the foregoing provisions, if Executive provides services for the Company as both an employee and as a non-employee director, to the extent permitted by Treas. Reg. §1.409A-1(h)(5) the services provided by such Executive as a non-employee director shall not be taken into account in determining whether the Executive has experienced a Separation from Service.

q. “Target Bonus” shall mean the target bonus for Executive under any annual bonus plan in effect from time to time as determined by the Compensation Committee (the “Committee”) or the Board.

r. “Termination Date” shall mean the date upon which a Separation from Service with respect to an Executive occurs.

2. Term of Change In Control Agreement.

a. This Agreement shall be for an initial term (the “Initial Term”) of two years and shall continue to renew for consecutive two year terms thereafter (a “Renewal Term”), unless either party shall give written notice to the other (a “Notice of Non-Renewal”) that such agreement shall not renew at least ninety days prior to the expiration of the Initial Term or Renewal Term then in effect. Notwithstanding the foregoing, the Company may not give a Notice of Non-Renewal during the Change In Control Protection Period.

b. This Agreement, except those provisions which shall survive under Section 11(k), shall terminate upon the termination of Executive’s employment for any reason other than the termination of Executive’s employment during the Change In Control Protection Period (x) by the Company without Cause or (y) by the Executive with Good Reason. No payment under this Agreement will be due to Executive upon termination of Executive’s employment for any reason other than as specified in (x) or (y) above.

3. Executive’s Incumbent Position.

a. Unless notified otherwise by the Chief Executive Officer of the Company or the Board, Executive shall serve as Executive Vice President & President Ticona (“Executive’s Incumbent Position”). In such position, Executive shall have such duties and authority as shall be determined from time to time by the Chief Executive Officer and the Board. If requested, Executive shall also serve as a member of the Board without additional compensation. The period during which the Executive shall be employed by the Company shall be called the “Service Term.”

b. Except as provided in Section 5, (i) either Company or Executive may terminate the employment relationship at any time, with or without Cause or Good Reason, (ii) this Agreement shall not be construed as giving the Executive any right to be retained in the employ of the Company or its Affiliates, (iii) the Company may at any time terminate the Executive free from any liability of any claim under this Agreement, except as expressly provided herein; and (iv) the Company may demote Executive at any time in its absolute and sole discretion without liability to the Executive.

c. During the Service Term, Executive will devote Executive’s full business time and best efforts to the performance of Executive’s duties hereunder and will not engage in any other business, profession or occupation for compensation or otherwise which would conflict or interfere with the rendition of such services either directly or indirectly, without the prior written consent of the Board; provided that nothing herein shall preclude Executive, (i) subject to the prior approval of the Board, from accepting appointment to or continuing to serve on any board of directors or trustees of any business corporation or any charitable organization or (ii) from participating in charitable activities or managing personal investments; provided in each case, and in the aggregate, that such activities do not conflict or interfere with the performance of Executive’s duties hereunder or conflict with Sections 7 or 8. Executive shall promote the goodwill of the Company with its employees, customers, stockholders, vendors, and the general public. During the Service Term, reasonable business expenses incurred by Executive in the performance of Executive’s duties hereunder and to support the goodwill and business relationships of the Company shall be reimbursed by the Company in accordance with Company policies.

4. Obligations of the Company upon Change In Control with Respect to Long-Term Incentive Awards and Deferred Compensation.

The effect of a change in control on any long-term incentive awards (cash or equity) or deferred compensation previously granted to the Executive under the 2008 Deferred Compensation Plan, 2004 Stock Incentive Plan or the 2004 Deferred Compensation Plan, as amended, (the “Long-Term Incentive Awards”) shall be governed by the terms and conditions of the applicable individual award agreements or deferral agreements and the Celanese Corporation 2008 Deferred Compensation Plan, the 2004 Stock Incentive Plan or the 2004 Deferred Compensation Plan, as amended (collectively, the “Long-Term Incentive Award Agreements”), and shall not be governed by this Agreement.

5. Termination of Employment Connected with a Change In Control.

a. Upon Executive’s Separation from Service during the Change In Control Protection Period, Executive shall receive the Change In Control Payment if and only if the following conditions occur:

(i) The Change In Control is consummated;

(ii) Executive is employed in the Executive Incumbent Position or some substantially equivalent or higher position for the Company as of the commencement of the Change In Control Protection Period;

(iii) Executive’s employment is terminated either by the Company without Cause or by the Executive with Good Reason such that a Separation from Service occurs;

(iv) Within fifty (53) days after both conditions in Sections 5(a)(i) and 5(a)(iii), or at the expiration of twenty-one (21) days following the presentation of the release, Executive executes a release of all claims, known or unknown, against the Company, its Affiliates, and their respective agents in a form satisfactory to the Company similar to that attached hereto as Exhibit A and does not timely revoke such release before the expiration of seven days following his or her execution of the release; and

(v) Within fifty (53) days after both conditions in Sections 5(a)(i) and 5(a)(iii), Executive reaffirms in writing in a manner satisfactory to the Company his or her obligations under Sections 7 and 8 of this Agreement.

b. The “Change In Control Payment” shall be equal to two times the sum of (i) Executive’s then current annualized base salary; and (ii) the higher of (x) Executive’s Target Bonus in effect on the last day of the Fiscal Year that ended immediately prior to the year in which the Termination Date occurs, or (y) the average of the cash bonuses paid by the Company to Executive for the three Fiscal Years preceding the Termination Date.

c. The Change In Control Payment shall be paid in a single lump sum to Executive six (6) months and one day after the Executive’s Termination Date, together with interest at the rate provided in Section 1274(b)(2)(B) of the Code.

d. Provided that (i) all of the conditions in Section 5(a) are met, (ii) Executive makes a timely COBRA election, and (iii) Executive has complied in all material respects with regard to the obligations of Sections 7 and 8 of this Agreement, if the Executive timely remits to the Company the applicable “COBRA” premiums for such coverage, the Company will continue to provide group health and dental coverage under the Company’s medical plan for Executive and his or her dependents during the Restricted Period; and will reimburse Executive for all premiums paid by Executive for such continued coverage. Such reimbursements will be made within thirty (30) days after Executive’s payment of such premiums (or submission of a request for reimbursement and satisfactory proof of such payment) but in no event later than on or before the last day of the Executive’s tax year following the tax year in which the expense was incurred. The amount of COBRA premiums and health and dental expenses eligible for reimbursement during Executive’s tax year may not affect the COBRA premiums and health and dental expenses eligible for reimbursement in any other tax year.

e. Certain Further Payments Due Executive

(i) In the event that any amount or benefit paid or distributed to Executive pursuant to this Agreement and/or any amounts or benefits otherwise paid or distributed to Executive by the Company that are treated as parachute payments under Section 280G of the Code (such payments, collectively, the “Covered Payments”), are or become subject to the tax imposed under Section 4999 of the Code or any similar tax that may hereafter

be imposed (the “Excise Tax”), the Company will pay to Executive an additional amount (the “Tax Reimbursement Payment”), such that the net amount retained by Executive with respect to such Covered Payments, after deduction of any Excise Tax (as well as any penalties and interest thereon) on the Covered Payments and any Federal, state and local income tax, payroll tax, and Excise Tax on the Tax Reimbursement Payment provided for by this subsection (e), but before deduction for any Federal, state or local income or employment tax withholding on such Covered Payments, will be equal to the amount of the Covered Payments, together with an amount equal to the product of any deductions disallowed to Executive for federal, state, or local income tax purposes because of the inclusion of the Tax Reimbursement Payment in Executive’s adjusted gross income multiplied by the highest applicable marginal rate of federal, state, or local income taxation, respectively, for the calendar year in which the Tax Reimbursement Payment is to be made. The time for payment of the Tax Reimbursement Payment is set forth in subsection (e)(v) below. The Tax Reimbursement Payment is intended to place the Executive in the same position he would have been in if the Excise Tax did not apply.

(ii) For purposes of determining whether any of the Covered Payments will be subject to the Excise Tax and the amount of such Excise Tax,

(A) such Covered Payments will be treated as “parachute payments” within the meaning of Section 280G of the Code, and all “parachute payments” in excess of the “base amount” (as defined under Section 280G(b)(3) of the Code) will be treated as subject to the Excise Tax, unless, and except to the extent that, in the good faith judgment of a public accounting firm appointed by the Company or tax counsel selected by such accounting firm (the “Accountants”), the Company has a reasonable basis to conclude that such Covered Payments (in whole or in part) either do not constitute “parachute payments” or represent reasonable compensation for personal services actually rendered (within the meaning of Section 280G(b)(4)(B) of the Code) in excess of the “base amount,” or such “parachute payments” are otherwise not subject to such Excise Tax; and

(B) the value of any non-cash benefits or any deferred payment or benefit will be determined by the Accountants in accordance with the principles of Section 280G of the Code.

(iii) For purposes of determining the amount of the Tax Reimbursement Payment, Executive will be deemed to pay:

(A) Federal income taxes at the highest applicable marginal rate of Federal income taxation for the calendar year in which the Tax Reimbursement Payment is to be made; and

(B) any applicable state and local income taxes at the highest applicable marginal rate of taxation for the calendar year in which the Tax Reimbursement Payment is to be made, net of the maximum reduction in Federal income taxes which could be obtained from the deduction of such state or local taxes if paid in such year.

(iv) In the event that the Excise Tax amount, if any, initially determined to be payable to the United States Treasury Department pursuant to this subsection

(e) is later determined by the Accountants or pursuant to any proceeding or negotiations with the Internal Revenue Service to exceed the amount taken into account hereunder at the time the Tax Reimbursement Payment was initially determined (including, but not limited to, by reason of any payment the existence or amount of which could not be determined at the time of the Tax Reimbursement Payment), the Company will make an additional Tax Reimbursement Payment, in respect of such excess (including making a full Tax Reimbursement Payment in the event of an initial determination that no Excise Tax amount was due) (as well as any interest or penalty payable with respect to such payment) at the time specified in subsection (e)(v) below.

In the event that the Excise Tax is subsequently determined by the Accountants or pursuant to any proceeding or negotiations with the Internal Revenue Service to be less than the amount taken into account under this subsection (e) in calculating the Tax Reimbursement Payment made, Executive will repay to the Company, at the time specified in subsection (e)(v) below, the portion of such prior Tax Reimbursement Payment that would not have been paid if the amount of the Excise Tax had been accurately calculated in determining such Tax Reimbursement Payment, plus interest on the amount of such repayment at the rate provided in Section 1274(b)(2)(B) of the Code. Notwithstanding the foregoing, in the event any portion of the Tax Reimbursement Payment to be refunded to the Company has been paid to any Federal, state or local tax authority, repayment thereof will not be required until actual refund or credit of such portion has been made to Executive, and interest payable to the Company will not exceed interest received or credited to Executive by such tax authority for the period it held such portion. Executive and the Company will mutually agree upon the course of action to be pursued (and the method of allocating the expenses thereof) if Executive’s good faith claim for refund or credit is denied (in whole or in part); provided that Executive will remain responsible to repay the Company for any such unrefunded Tax Reimbursement Payments to the extent Executive ultimately prevails in such claim.

(v) The Tax Reimbursement Payment (or portion thereof) provided for in this subsection (e) will be paid to Executive within 5 days after Executive remits the Excise Tax to the Internal Revenue Service but no later than the end of the Executive’s tax year following the tax year in which the Executive remits the Excise Tax to the Internal Revenue Service. Further, in the event that the initial Tax Reimbursement Payment was too little and additional Tax Reimbursement Payments are subsequently determined to be payable to Executive pursuant to subsection (e)(iv) above, such Tax Reimbursement Payment or additional Tax Reimbursement Payment amount will be made by the Company to Executive within 5 days after the date that Executive remits such portion to the Internal Revenue Service, but no later than the end of the Executive’s tax year following the tax year in which the Executive remits such portion to the Internal Revenue Service. In the event that the amount of the estimated Tax Reimbursement Payment exceeds the amount subsequently determined to have been due, subject to the provisions of subsection (e)(iv), such excess will be payable by Executive to the Company on the fifth (5th) business day after written demand by the Company for payment (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code). Company will reimburse the Executive for any interest, penalties or surcharge that may be imposed on the Executive in connection with any Excise Tax (including a reimbursement of any additional taxes imposed as a result of the reimbursement of any such interest, penalties or surcharge) within 5 days after payment by the Executive, but in no event later than on or before the last day of the Executive’s tax year following the tax year in which the interest, penalties, surcharge or other taxes are

imposed, such reimbursement obligation shall remain in effect during the applicable statute of limitations relating to any such interest, penalties or surcharge (but in no event shall remain in effect for longer than 10 years), and the amount of expenses eligible for reimbursement hereunder during Executive’s tax year will not affect the expenses eligible for reimbursement in any other tax year.

(vi) The Tax Reimbursement Payment due under this subsection (e) shall not exceed two million dollars ($2,000,000).

(vii) If the amount of the Covered Payments is equal to or less than 110% of the product of 2.99 and Executive’s applicable “base amount” (as such term is defined for purposes of Section 4999 of the Code), the Covered Payments under this Agreement or otherwise shall be reduced by the minimum amount necessary so that none of the Covered Payments are subject to the excise tax under Section 4999 of the Code; provided, however, that this subsection (e)(vii) shall not apply if, even after all Covered Payments due hereunder are reduced to zero, the value of the Covered Payments would still be subject to the excise tax under Section 4999 of the Code, in which case no reduction of any Covered Payments shall be made.

f. Notwithstanding any provision of this Agreement to the contrary, if Executive is a “Specified Employee” within the meaning of Treasury Regulation §1.409A-1(i) and if any payment under this Agreement provides for a “deferral of compensation” within the meaning of Treasury Regulation §1.409A-1(b) and if such payment would otherwise occur before the date that is six (6) months after the Executive’s Termination Date, then such payment shall be delayed and shall occur on the date that is six (6) months and one (1) day after the Termination Date (or, if earlier, the date of the Executive’s death), together with interest at the rate provided in Section 1274(b)(2)(B) of the Code.

6. Exclusivity of Benefits. Executive acknowledges that this Agreement supercedes and replaces all prior agreements or understandings Executive may have with the Company with respect to compensation or benefits that may become payable in connection with or as a result of a change in control of the Company, whether or not such change in control constitutes a Change In Control, including any provisions contained in any employment agreement, offer letter or change in control agreement, except with respect to any Long-Term Incentive Awards which shall be governed by the terms of the Long-Term Incentive Award Agreements. This Agreement also describes all payments and benefits that the Company shall be obligated to provide to Executive upon Executive’s Separation from Service during a Change In Control Protection Period and shall constitute Executive’s agreement to waive any rights to payment under the Celanese Americas Separation Pay Plan, any similar or successor plan adopted by the Company, and any other term of employment contained in any employment agreement, offer letter, change in control agreement or otherwise (other than benefits to which he/she may be entitled, if any: (i) under any Celanese plan qualified under Section 401(a) of the Internal Revenue Code, including the Celanese Americas Retirement Pension Plan and Celanese Americas Retirement Savings Plan; and (ii) under the 2008 Celanese Deferred Compensation Plan) to the extent that the circumstances giving right to such right to payment would constitute a Separation of Service during a Change In Control Protection Period.

7. Confidentiality; Intellectual Property.

a. Confidentiality.

(i) Based upon the assurances given by the Executive in this Agreement, the Company will provide Executive with access to its Confidential Information. Executive hereby reaffirms that all Confidential Information received by Executive prior to the termination of this Agreement is the exclusive property of the Company and Executive releases any individual claim to the Confidential Information.

(ii) Executive will not at any time (whether during or after Executive’s employment with the Company) (x) retain or use for the benefit, purposes or account of Executive or any other Person; or (y) disclose, divulge, reveal, communicate, share, make available, transfer or provide access to any Person outside the Company (other than its professional advisers who are bound by confidentiality obligations), any Confidential Information without the prior written authorization of the Board.

(iii) Executive agrees to keep and maintain adequate and current written records (in the form of notes, sketches, drawings, and any other form or media requested by the Company) of all Company Works. The records will be available to and remain the sole property and intellectual property of the Company at all times.

c. In the event Executive leaves the employ of the Company, Executive hereby grants consent to notification by the Company to any subsequent employer about Executive’s rights and obligations under this Agreement.

8. Non-Competition; Non-Solicitation.

a. Executive acknowledges and recognizes the highly competitive nature of the businesses of the Company and its Affiliates and accordingly agrees as follows:

(i) During the Service Term and for the Restricted Period, Executive will not, whether on Executive’s own behalf or on behalf of or in conjunction with any Person, directly or indirectly solicit or assist in soliciting in competition with the Company or its Affiliates, the business of any customer, prospective customer, client or prospective client:

(A) with whom Executive had personal contact or dealings on behalf of the Company or its Affiliates during the one year period preceding the termination of Executive’s employment;

(B) with whom employees directly or indirectly reporting to Executive have had personal contact or dealings on behalf of the Company or its Affiliates during the one-year immediately preceding the termination of Executive’s employment; or

(C) for whom Executive had direct or indirect responsibility during the one year period immediately preceding the termination of Executive’s employment.

(ii) During the Restricted Period, Executive will not directly or indirectly:

(A) engage in any Competitive Business;

(B) enter the employ of, or render any services to, any Person (or any division or controlled or controlling affiliate of any Person) who or which engages in a Competitive Business;

(C) acquire a financial interest in, or otherwise become actively involved with, any Competitive Business, directly or indirectly, as an individual, partner, stockholder, officer, director, principal, agent, trustee or consultant; or

(D) interfere with, or attempt to interfere with, business relationships (whether formed before, on or after the date of this Agreement) between the Company or any of its Affiliates and customers, clients, suppliers partners, members or investors of the Company or its Affiliates.

(iii) Notwithstanding anything to the contrary in this Agreement, Executive may directly or indirectly own, solely as an investment, securities of any Person engaged in the business of the Company or its Affiliates which are publicly traded on a national or regional stock exchange or on the over-the-counter market if Executive (i) is not a controlling Person of, or a member of a group which controls, such Person and (ii) does not, directly or indirectly, own 5% or more of any class of securities of such Person.

(iv) During the Restricted Period, Executive will not, whether on Executive’s own behalf or on behalf of or in conjunction with any Person, directly or indirectly:

(A) solicit, interview, encourage, or take any other action that would tend to influence in any manner any employee of the Company or its Affiliates to leave the employment of the Company or its Affiliates (other than as a result of a general advertisement of employment made by Executive’s subsequent employer or business, not directed at any such employee); or

(B) hire any such employee who was employed by the Company or its Affiliates as of the Termination Date or who left the employment of the Company or its Affiliates coincident with, or within one year prior to or after, the Termination Date.

(v) During the Restricted Period, Executive will not, directly or indirectly, solicit or encourage any consultant then under contract with the Company or its Affiliates to cease to work with the Company or its Affiliates.

b. It is expressly understood and agreed that although Executive and the Company consider the restrictions contained in this Section 8 to be reasonable, if a final judicial determination is made by a court of competent jurisdiction that the time or territory or any other restriction contained in this Agreement is an unenforceable restriction against Executive, the provisions of this Agreement shall not be rendered void but shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable. Alternatively, if any court of competent jurisdiction finds that any restriction contained in this Agreement is unenforceable, and such restriction cannot be amended so as to make it enforceable, such finding shall not affect the enforceability of any of the other restrictions contained herein.

c. Prior to the commencement thereof, Executive will provide written notice to the Company of any employment or other activity that would potentially violate the provisions of Sections 7 or 8 and, if Executive wishes to do so, Executive may ask the Board to modify or waive the protections of this Section 8, but nothing in this Agreement shall limit in any manner the Board’s absolute discretion not to do so.

9. Enforcement of Promises Concerning the Protection of the Company’s Confidential Information and Goodwill. Executive acknowledges and agrees that the Company’s remedies at law for a breach or threatened breach of any of the provisions of Section 7 or Section 8 would be inadequate and the Company would suffer irreparable damages as a result of such breach or threatened breach. In recognition of this fact, Executive agrees that, in the event of such a breach in or threatened breach, in addition to any remedies at law, the Company, without posting any bond, shall be entitled to obtain equitable relief in the form of specific performance, temporary restraining order, temporary or permanent injunction or any other equitable remedy which may then be available. In addition, and without limiting the Company’s ability to obtain such equitable relief, Executive shall not be entitled to any Change In Control Payment if Executive materially violates the provisions of Sections 7 or 8 and, to the extent that such payments have already been made, Executive shall repay all Change In Control Payments immediately upon demand by the Company.

10. Section 409A Acknowledgement and Release. Executive understands that payments under this Agreement are potentially subject to Section 409A of the Code and that if this Agreement does not satisfy an exception to Code Section 409A or does not comply with the requirements of Section 409A and the applicable guidance thereunder, then Executive may incur adverse tax consequences under Section 409A. Executive acknowledges and agrees that (a) Executive is solely responsible for all obligations arising as a result of the tax consequences associated with payments under this Agreement including, without limitation, any taxes, interest or penalties associated with Section 409A, (b) Executive is not relying upon any written or oral statement or representation by the Company or any Affiliate thereof, or any of their respective employees, directors, officers, attorneys or agents (collectively, the “Company Parties”) regarding the tax effects associated with the execution of this Agreement and the payment under this Agreement, and (c) in deciding to enter into this Agreement, Executive is relying on his or her own judgment and the judgment of the professionals of his or her choice with whom Executive has consulted. Executive hereby releases, acquits and forever discharges the Company Parties from all actions, causes of actions, suits, debts, obligations, liabilities, claims, damages, losses, costs and expenses of any nature whatsoever, known or unknown, on account of, arising out of, or in any way related to the tax effects associated with the execution of this Agreement and any payment hereunder.

11. Miscellaneous.
