12 VP/#56000596 (c) Payroll and Tax Matters. (i) All compensation payments made under this Agreement will be subject to required payroll taxes and withholding. Specifically, under the tax equalization program, the Executive is responsible for stay-at-home federal, state (Florida), U.S. Social Security, and Medicare taxes on the payments made under Section 6 this Agreement. The Executive is only responsible for the U.S. Social Security and Medicare taxes on stay-at-home income, which excludes the housing, education allowance, automobile, cost of living adjustment, and relocation reimbursement. In the event hypothetical income taxes are withheld from the payments detailed in Section 6 of this Agreement in a manner that results in interest or penalties, such interest and penalties arising from income from the Company would be covered by the Company. (ii) In the event any payment or benefit to be provided to the Executive by the Company is potentially subject to additional tax in the Netherlands due to the payment or benefit being categorized as post-employment compensation, severance compensation, excessive termination payments, or a similar categorization, the Executive agrees to: (A) cooperate with the Company in modifying and/or restructuring such payment or benefit in order to avoid such additional tax, and (B) take any needed steps to achieve such modification or restructuring, including, but not limited to, entering into any reasonable amendment to this Agreement; provided, however, that the effect of such cooperation and/or steps is not financially detrimental to the Executive. (d) Compliance with Company Policies. Payments made under this Agreement shall be subject to any generally applicable Company policy, or action, related to recoupment (claw-back) or other modification to executive compensation, (i) as in place from time-to-time during the period beginning on the Effective Date and ending on the Separation Date, and (ii) as in place after the Separation Date so long as required by applicable law, regulation, or stock exchange listing rule. (e) Integration; Amendment. Except as is otherwise provided herein, this Agreement contains all of the terms and conditions agreed upon by the parties relating to the subject matter of this Agreement and supersedes all prior and contemporaneous agreements, negotiations, correspondence, undertakings and communications of the parties, whether oral or written, respecting the subject matter of this Agreement. This Agreement may not be amended, altered or modified without the prior written consent of both parties and such instrument must acknowledge that it is an amendment or modification of this Agreement. (f) Counterparts. This Agreement may be executed in counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument. Counterpart signature pages to this Agreement transmitted by facsimile transmission, by electronic mail in portable document format (.pdf), or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document (including execution via DocuSign), will have the same effect as physical delivery of the paper document bearing an original signature. (g) Waiver. Waiver of any term or condition of this Agreement by any party will not be construed as a waiver of a subsequent breach or failure of the same term or condition, DocuSign Envelope ID: C7F34DFC-DF23-4AA8-B3FA-47061DD7598F

 
13 VP/#56000596 or a waiver of any other term or condition of this Agreement. Any waiver must be in writing. (h) Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held by a court of competent jurisdiction to be prohibited or unenforceable for any reason, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement. (i) Captions. The captions in this Agreement are not part of its provisions, are merely for reference and have no force or effect. If any caption is inconsistent with any provision of this Agreement, such provision will govern. (j) Governing Law; Arbitration. The validity, interpretation, construction, enforcement and remedies of, or relating to, this Agreement, and the rights and obligations of the parties hereunder, will be governed by and construed in accordance with the substantive laws of the State of Illinois, without regard to the conflict of law principles, rules or statutes of any jurisdiction. Subject to Section 9 above, any action or proceeding to enforce, or arising out of, this Agreement will be submitted to arbitration via the American Arbitration Association, employment rules, and will be heard by a single arbitrator sitting in Chicago, Illinois. The Company shall reimburse the Executive for the reasonable travel and hotel expenses incurred in connection with traveling to, and staying in, Chicago, Illinois for the purpose of attending an arbitration proceeding in Chicago, Illinois. The reimbursement will be limited to expenses for the Executive and for one lawyer for the Executive. (k) Notice. All notices given hereunder will be in writing and will be sent by internationally recognized overnight delivery service, or delivered by hand. If intended for the Company, notices will be addressed to it or delivered to it at its principal office to the attention of the Chief Human Resources Officer of the Company. If intended for the Executive, notices will addressed to the Executive’s then current residence address as shown on the Company’s records, or to such other address as the Executive directs in a notice to the Company. All notices will be deemed to be given on the date received at the address of the addressee. (l) Code Section 409A. The parties intend that this Agreement and the benefits provided hereunder be interpreted and construed to comply with Section 409A of the Internal Revenue Code of 1986, as amended, and all regulatory and interpretative guidance issued thereunder (“Code Section 409A”) to the extent applicable thereto. The time and form of payment of incentive compensation, disability benefits, severance payments, expense reimbursements and payments of in-kind benefits described herein will be made in accordance with the applicable sections of this Agreement, provided that with respect to termination of employment for reasons other than death, the payment at such time can be characterized as a “short-term deferral” for purposes of Code Section 409A or as otherwise exempt from the provisions of Code Section 409A, or if any portion of the payment cannot be so characterized, and the Executive is a “specified employee” under Code Section 409A, such portion of the payment will be delayed until the earlier to occur of the Executive’s death or the date that is six months and one day following the Executive’s termination of employment (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this section will be paid or reimbursed to the Executive DocuSign Envelope ID: C7F34DFC-DF23-4AA8-B3FA-47061DD7598F

 
14 VP/#56000596 in a lump sum, and any remaining payments due under this Agreement will be payable at the same time and in the same form as such amounts would have been paid. Further, if the Executive is a “specified employee” and if any equity-based awards granted to the Executive by the Company, pursuant to this Agreement or otherwise, continue to vest upon the Executive’s termination of employment, and are deemed a “deferral of compensation” (as such term is described under Code Section 409A), the equity- based awards will not be settled or released until the expiration of the Delay Period. For purposes of applying the provisions of Code Section 409A, each separately identifiable amount to which the Executive is entitled will be treated as a separate payment. The time or schedule of any payment or amount scheduled to be paid pursuant to the terms of this Agreement, including but not limited to any restricted stock unit or other equity-based award, payment or amount that provides for the “deferral of compensation” (as such term is described under Code Section 409A), may not be accelerated except as otherwise permitted under Code Section 409A and the guidance and Treasury regulations issued thereunder. For purposes of this Agreement, the terms “retirement,” “termination of employment,” “terminated,” “termination,” “this Agreement will be terminated” and variations thereof, as used in this Agreement, are intended to mean a termination of employment that constitutes a “separation from service” under Code Section 409A. If the sixty (60)-day period following a “separation from service” begins in one calendar year and ends in a second calendar year (a “Crossover 60-Day Period”) and if there are payments due the Executive that are subject to Code Section 409A (and not exempt from Code Section 409A) that are: (i) conditioned on the Executive signing and not revoking a release of claims and (ii) otherwise due to be paid during the portion of the Crossover 60-Day Period that falls within the first year, then such payments will be delayed and paid in a lump sum during the portion of the Crossover 60-Day Period that falls within the second year. Although the Company intends to administer the Agreement so that it will comply with the requirements of Code Section 409A, the Company does not represent or warrant that the Agreement will comply with Code Section 409A or any other provision of federal, state, local, or non-United States law. Provided that the Company administers this Agreement in a manner consistent with the terms of this Agreement, neither the Company, its subsidiaries, nor their respective directors, officers, employees or advisers will be liable to the Executive (or any other individual claiming a benefit through the Executive) for any tax, interest, or penalties the Executive may owe as a result of compensation paid under the Agreement, and the Company and its subsidiaries will have no obligation to indemnify or otherwise protect the Executive from the obligation to pay any taxes pursuant to Code Section 409A. Payment or reimbursement of the Executive’s expenses will be made promptly and in no event later than December 31 of the year following the year in which such expenses were incurred, and the amount of such expenses eligible for payment or reimbursement, or in-kind benefits provided, in any year will not affect the amount of such expenses eligible for payment or reimbursement, or in-kind benefits to be provided, in any other year. Additionally, any right to expense reimbursement or in- kind benefits will not be subject to liquidation or exchange for another benefit. DocuSign Envelope ID: C7F34DFC-DF23-4AA8-B3FA-47061DD7598F

 
15 VP/#56000596 The provisions of this Agreement will be construed in a manner in favor of complying with any applicable requirements of Code Section 409A to avoid taxation under Code Section 409A. If any compensation or benefits provided by this Agreement result in the application of Code Section 409A, the Company will modify this Agreement in the least restrictive manner necessary in order to comply with the provisions of Code Section 409A, other applicable provisions of the Code and/or any rules, regulations or other regulatory guidance issued under such statutory provisions and, in each case, without material diminution in the value of the payments or benefits to the Executive.
