represents that Executive has consulted with independent legal counsel regarding Executive’s rights and obligations under this Agreement and that Executive fully understands the terms and conditions contained in this Agreement. 

15.14 Sect ion 409A. 

(a) General Compliance. This Agreement is intended to comply with Section 409A of the Code and the regulations and guidance
thereunder (“Section 409A”) or an exemption therefrom and shall be construed and administered in accordance with this intent. Notwithstanding any other provision of this Agreement, payments provided under this
Agreement may only be made upon an event and in a manner that complies with Section 409A 

  
 14 













 
or an applicable exemption. Any payments under this Agreement that may be excluded from Section 409A either as separation pay due to an involuntary separation from service or as a short term
deferral shall be excluded from Section 409A to the maximum extent possible. For purposes of Section 409A, each installment payment provided under this Agreement shall be treated as a separate payment. Any payments to be made under this
Agreement upon a termination of employment shall only be made upon a “separation from service” under Section 409A. Notwithstanding the foregoing, the Company makes no representations that the payments and benefits provided under this
Agreement comply with Section 409A and in no event shall the Employing Entity be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by Executive on account of
non-compliance with Section 409 A. 
 (b) Specified Employees. Notwithstanding any other
provision of this Agreement, if any payment or benefit provided to Executive in connection with his termination of employment is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A and
Executive is determined to be a “specified employee” as defined in Section 409A(a)(2)(b)(i) who is subject to a six-month delay in payment, then such payment or benefit shall not be paid until
the first payroll date to occur following the six-month anniversary of the termination date or, if earlier, on Executive’s death. 

(c) Reimbursements. Notwithstanding to the contrary in this Agreement or the Employing Entity policy with respect to such payments, in
kind benefits and reimbursements provided under this Agreement during any tax year of Executive shall not affect in kind benefits or reimbursements to be provided in any other tax year of Executive and are not subject to liquidation or exchange for
another benefit. Notwithstanding anything to the contrary in this Agreement, reimbursement be timely submitted by Executive and, if timely submitted, reimbursement payment shall be made to Executive in accordance with the Employing Entity’s
policies regarding reimbursements, but in no event later than the last day of the taxable year following the taxable year in which the expense was incurred. This Section 5.14(c) shall only apply to in kind benefits and reimbursements that would
result in taxable compensation income to Executive. 
 15.15 Section 280G. In the event that the compensation and other benefits
provided for in this Agreement or otherwise payable to Executive (i) constitute “parachute payments” within the meaning of Section 280G of the Code and (ii) but for this Section 15.15, would be subject to the excise tax
imposed by Section 4999 of the Cede or would be non deductible under Section 280G of the Code, then such pay and benefits will be either: 

(a) delivered in full, or 
 (b)
delivered as to such lesser extent which would result in no portion of such compensation and other benefits being nondeductible under Section 280G of the Code or subject to excise tax under Section 4999, of the Code, whichever of the
foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, results in the receipt by Executive on an after-tax basis, of the
greatest amount of compensation and benefits, notwithstanding that all or some portion of such compensation and benefits may be taxable under Section 4999 of the Code. If a reduction is required pursuant to the preceding sentence, the reduction
shall occur in the manner (the “Reduction Method”) that 

  
 15 













 
results in the greatest economic benefit for Executive. If more than one method of reduction will result in the same economic benefit, the items so reduced will be reduced pro rata (the
“Pro Rata Reduction Method”). Notwithstanding the foregoing, if the Reduction Method or the Pro Rata Reduction Method would result in any portion of the payments being subject to taxes pursuant to Section 409A of the Code that
would not otherwise be subject to taxes pursuant to Section 409A of the Code, then the Reduction Method and/or die Pro Rata Reduction Method, as the case may be, shall he modified so as to avoid the imposition of taxes pursuant to
Section 409A of the Code as follows: (A) as a first priority, the modification shall preserve to the greatest extent possible, the greatest economic benefit for Executive as determined on an
after-tax basis; (B) as a second priority, the payments that are contingent on future events (e.g., being terminated without Cause), shall be reduced (or eliminated) before the payments that are not
contingent on future events: and (C) as a third priority, the payments that are “deferred compensation” within the meaning of Section 409A of the Code shall be reduced (or eliminated) before the Contingent Payments that are not
deferred compensation within the meaning of Section 409A of the Code. Unless the Company and Executive otherwise agree in writing, any extermination required under this Section will be made in writing by accountants designated by the Company
immediately prior to Change in Control (the “Accountants”), whose determination will be conclusive and binding upon Executive and the Company for all purposes for purposes of making the calculations required by this Section, the
Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Executive will
furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section. The Company will bear all costs the Accountants may reasonably incur in connection with any
calculations contemplated by this Section 15.15. 
 The Company shall make reasonable efforts to procure a vote under the Code
Section 280G regulations rendering Code Section 280G inapplicable to payments to Executive. 
 15.16 United States Federal and
State Withholding Taxes. The Employing Entity shall deduct the amount of all required United Slates federal and state and any other withholding taxes to be deducted from any amounts payable to Executive pursuant to this Agreement in accordance
with Executive’s Form W-4 on file with the Employing Entity and all applicable employment taxes. 

15.17 Severability. If any provision, portion or clause of this Agreement as applied in whole or in part to any circumstances is ruled
by an arbitrator or court of competent jurisdiction to be invalid or unenforceable, then the ruling shall not affect any other provision, portion or clause of this Agreement, the application of such provision, portion or clause in any other
circumstances or jurisdiction, or the validity or enforceability of this Agreement as a whole or any other provision, portion or clause hereof. 

15.18 Entire Agreement. This Agreement contains the entire agreement of the parties with respect to Executive’s employment and his
and the Employing Entity’s undertakings as contemplated by this Agreement, and supersedes all prior understandings and agreements of the parties and their affiliates, whether written or oral, with respect to the subject matter of this Agreement
(including, without limitation, the Prior Employment Agreement). 

  
 16 













 15.19 Confidentiality of Agreement. This Agreement and its terms shall be kept
confidential by Executive, except that Executive may disclose the terms of this Agreement on a confidential basis to Executive’s attorneys and accountants and to Executive’s family. 

15.20 Execution in Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original and all of
which, together, shall constitute a single instrument. Any counterpart signed or delivered by electronic means intended to preserve the original graphic and pictorial appearance of a document, or by any combination of such means, shall constitute
effective execution and delivery thereof.
