4.1.Disability. If the Employee dies, then the Employee’s employment by the Company hereunder shall automatically terminate on the date of the Employee’s death.

In the case of a Disability, until the Employee becomes eligible for disability income under the Company’s disability income insurance (if any) or until the Company shall have terminated the Employee’s service in accordance with the foregoing, whichever shall first occur, to the extent permitted by the terms of the Company’s plans, the Employee will be entitled to receive compensation, at the rate and in the manner provided in Section 3.1, notwithstanding any such physical or mental disability. Termination pursuant to this Section 4.1 is hereinafter referred to as an “Involuntary Termination”.

Notwithstanding any such designation, the Employee shall continue to receive the Base Salary and benefits in accordance with Section 3 of this Agreement until the Employee becomes eligible for disability income under the Company’s disability income insurance (if any) or until the termination of the Employee’s employment, whichever occurs first.

4.3.Disability Income Payments.

If any question arises as to whether during any period the Employee is disabled through any illness, injury, accident or condition of either a physical or psychological nature so as to be unable to perform substantially all of the Employee’s duties and responsibilities hereunder, the Employee may, and at the request of the Company shall, submit to a medical examination by a physician selected by the Company to whom the Employee or the Employee’s guardian has no reasonable objection to determine whether the Employee is so disabled and such determination shall for the purposes of this Agreement be conclusive of the issue. If such question arises and the Employee fails to submit to such medical examination, the Company’s determination of the issue shall be binding on the Employee.

4.4.Termination by the Company for Cause. The Company may terminate the employment of the Employee hereunder at any time during the Employment Period for Cause (as defined below) (such termination being referred to in this Agreement as a “Termination for Cause”) by giving the Employee notice of such termination, upon the giving of which such termination shall take effect immediately.

4.5.Termination by the Company without Cause. The Company may terminate the employment of the Employee hereunder at any time during the Employment Period without “Cause” (such termination referred to in this Agreement as a “Termination without Cause”).

4.6.Termination by the Employee for Good Reason. The Employee may terminate his employment hereunder at any time for Good Reason (as defined below) by giving the Company written notice of such termination, provided that such notice specifies: (a) the basis for termination and (b) the effective date of termination (such termination being referred to in this Agreement as a “Termination for Good Reason”).

(d)For purposes of this Agreement, “Change in Control” means the occurrence of any of the following:

(i)any one person, or more than one person acting as a group (“Person”), acquires ownership of the stock of the Parent Company that, together with the stock held by such Person, constitutes more than 50% of the total voting power of the stock of the Parent Company, except that any change in the ownership of the stock of the Parent Company as a result of a private financing of the Parent Company that is approved by the Board will not be considered a Change in Control;

(ii)a majority of members of the Board is replaced during any twelve- (12-) month period by directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election; or

(iii)any Person acquires (or has acquired during the twelve- (12- ) month period ending on the date of the most recent acquisition by such person or persons) assets from the Parent Company that have a total gross fair market value equal to or more than 50% of the total gross fair market value of all of the assets of the Parent Company immediately prior to such acquisition or acquisitions. For purposes of this subsection (iii), gross fair market value means the value of the assets of the Parent Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets.

For purposes of this definition, Persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Parent Company. Further and for the avoidance of doubt, a transaction will not constitute a Change in Control if: (i) its sole purpose is to re-domicile the Parent Company in a jurisdiction other than its original jurisdiction of incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the Parent Company’s securities immediately before such transaction. With regard to any payment considered to be nonqualified deferred compensation under Section 409A (as defined below), to the extent applicable, that is payable upon a Change in Control, to avoid the imposition of an additional tax, interest or penalty under Section 409A (as defined below), no amount will be payable unless such change in control constitutes a “change in control event” within the meaning of Section 1.409A-3(i)(5) of the Treasury Regulations.

5.5.Conditions to Receipt of Severance. The obligation of the Company to make any payments and benefits (other than Final Compensation) to or on behalf of the Employee under Section 5.2, 5.3 or 5.4 above is conditioned on the Employee or, as applicable, his beneficiary or estate signing and not revoking a separation agreement and release of claims in a form reasonably satisfactory to the Company (the “Release of Claims”), provided that such separation agreement and release of claims becomes effective and irrevocable no later than sixty (60) days following the termination date (such deadline, the “Release Deadline”). If the Release of Claims does not become effective by the Release Deadline, the Employee or his beneficiary or estate will forfeit any rights to severance or benefits (other than Final Compensation) under this Agreement. In no event will severance payments or benefits (other than Final Compensation) be paid or provided under this Agreement until such Release of Claims becomes effective and irrevocable. The first installment of any severance payments to which the Employee or his beneficiary or estate becomes entitled will be paid on the Company’s next regular payday that is at least sixty (60) days following the termination date, retroactive to the day following the termination date. If the sixty (60) day period following termination referred to herein extends through two (2) taxable years, to the extent required to comply with Section 409A, such amount will be paid in the second taxable year (but within the sixty (60) day period) following the Employee’s termination.

5.6.Section 409A. Notwithstanding anything to the contrary in this Agreement, if at the time the Employee’s employment terminates, the Employee is a “specified employee,” as defined below, any and all amounts payable under this Agreement on account of such separation from service that would (but for this provision) be payable within six (6) months following the date of termination, shall instead be paid on the next business day following the expiration of such six- (6-) month period or, if earlier, upon the Employee’s death; except (a) to the extent of amounts that do not constitute a deferral of compensation within the meaning of Treasury regulation Section 1.409A-1(b) (including without limitation by reason of the safe harbor set forth in Section 1.409A-1(b)(9)(iii), as determined by the Company in its reasonable good faith discretion); (b) benefits which qualify as excepted welfare benefits pursuant to Treasury regulation Section 1.409A-1(a)(5); or (c) other amounts or benefits that are not subject to the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”). For purposes of this Agreement, all references to “termination of employment” and correlative phrases shall be construed to require a “separation from service” (as defined in Section 1.409A-1(h) of the Treasury regulations after giving effect to the presumptions contained therein), and the term “specified employee” means

an individual determined by the Company to be a specified employee under Treasury regulation Section 1.409A-1(i). Each payment made under this Agreement shall be treated as a separate payment and the right to a series of installment payments under this Agreement is to be treated as a right to a series of separate payments. In no event shall the Company or any of its Affiliates have any liability relating to the failure or alleged failure of any payment or benefit under this Agreement to comply with, or be exempt from, the requirements of Section 409A.

5.7.Limitations on Payments. Notwithstanding anything in this Agreement or elsewhere to the contrary, in the event that any payment or benefit received or to be received by the Employee under this Agreement or otherwise (collectively, the “Payments”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) but for this Section 5.7, be subject to the excise tax imposed by Section 4999 of the Code, then the Payments shall be reduced (but not below zero) to the extent, but only to the extent, needed to ensure that no portion of the Payments constitutes a “parachute payment” within the meaning of Section 280G of the Code; provided, that no reduction in the Payments shall be made by reason of this Section 5.7 unless, on an after-tax basis taking into account the excise tax imposed by Section 4999 of the Code together with all applicable income taxes, the Payments payable to the Employee would be greater than if such reduction had not been made. Any reduction in the Payments required by the immediately preceding sentence shall be applied, first, against any cash severance payments, then against other payments and benefits to which Q&A 24(c) of Section 1.280G-1 of the Treasury Regulations does not apply, and finally against all remaining payments and benefits.

6.Compliance Agreement . For the avoidance of doubt, the Compliance Agreement executed and delivered by the Employee as of May 7, 2017 (the “Compliance Agreement”) remains in full force and effect and the terms and conditions thereof are specifically incorporated herein by reference. The obligation of the Company to make any payments (other than the Final Compensation) to or on behalf of the Employee under Section 5.3 or 5.4 above, and the Employee’s right to retain the same, is expressly conditioned upon the Employee’s continued performance of the Employee’s obligations under the Compliance Agreement.

7.Standards of Conduct. The Employee will conduct himself in an ethical and professional manner at all times and in accordance with any employee policies or guidelines which the Parent Company or the Company may issue from time to time.

8.3.Limitation on Indemnification. The Employee shall not be entitled to any indemnification under this Section 8 if the Employee knowingly violated any duty, responsibility or obligation imposed under this Agreement, the Compliance Agreement or any Company policy.
