amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect thein-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable year (except for any lifetime or other aggregate limitation applicable to medical expenses). Such right to reimbursement orin-kind benefits is not subject to liquidation or exchange for another benefit.

c.    To the extent that any payment or benefit described in this Agreement constitutes“non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Executive’s termination of employment, then such payments or benefits shall be payable only upon the Executive’s “separation from service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury RegulationSection 1.409A-1(h).

d.    The parties intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with, or are exempt from, Section 409A of the Code. Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury RegulationSection 1.409A-2(b)(2). The parties agree that this Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with, or be exempt from, Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.

e.    The Company makes no representation or warranty and shall have no liability to the Executive or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.

7.    Entire Agreement. This Agreement constitutes the entire agreement between Executive and the Company concerning Executive’s relationship with the Company, and supersedes and replaces any and all prior agreements and understandings between the Parties concerning Executive’s relationship with the Company, including that certain Offer Letter by and between the Company and the Executive, dated as of February 15, 2017; provided that, for the avoidance of doubt, the Restrictive Covenants and each of the award agreements applicable to the Executive’s outstanding equity awards shall continue to survive.

If any portion or provision of this Agreement (including, without limitation, any portion or provision of any section of this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.
