Section 6. Termination of Employment

(a) General Rule. Subject to the provisions of Section 6(b) hereof, the obligation of the Company to satisfy payment of an Award to a Participant hereunder is conditioned upon the continued employment of the Participant with the Company at the time determined by the Plan Administrator for payment of an Award. If the employment of a Participant with the Company is terminated for any reason, at any time prior to the time determined by the Plan Administrator for payment of an Award hereunder, the Award shall be forfeited and automatically be cancelled without further action of the Company, unless otherwise provided by the Plan Administrator.

(d) Governing Law. The Plan shall be governed by and construed in accordance with the laws of Delaware, without regard to the choice-of-law rules thereof.

(e) Section 409A. The Company intends that that payments and benefits under this Plan will either comply with or be exempt from Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations and guidance promulgated thereunder (collectively “Section 409A”) and, accordingly, to the maximum extent permitted, this Plan shall be interpreted to be exempt from Section 409A or in compliance therewith, as applicable. Nothing contained herein shall constitute any representation or warranty by the Company regarding compliance with Section 409A. The Company shall have no obligation to take any action to prevent the assessment of any additional income tax, interest or penalties under Section 409A on any person and the Company, its subsidiaries and affiliates, and each of their respective employees or representatives, shall have no liability to any person with respect thereto. A termination of employment shall not be deemed to have occurred for purposes of any provision of the Plan providing for the payment of any amounts or benefits that are considered nonqualified deferred compensation under Section 409A upon or following a termination of employment, unless such termination is also a “separation from service” within the meaning of Section 409A and the payment thereof prior to a “separation from service” would violate Section 409A. For purposes of any such provision of the Plan or relating to any such payments or benefits, references to a “termination,” “termination of employment,” or like terms shall mean “separation from service.” If an amount is paid in two or more installments, for purposes of Section 409A, each installment shall be treated as a separate payment. Notwithstanding any contrary provision in the Plan, any payment(s) of nonqualified deferred compensation (within the meaning of Section 409A) that are otherwise required to be made under the Plan to a “specified employee” (as defined under Section 409A) as a result of his or her separation from service (other than a payment that is not subject to Section 409A) shall be delayed for the first six months following such separation from service (or, if earlier, until the date of death of the specified employee) and shall instead be paid on the day that immediately follows the end of such six-month period.

(f) Accounting Restatement. If a Participant receives compensation pursuant to an Award under the Plan based on financial statements that are subsequently required to be restated in a way that would decrease the value of such compensation, the Participant will, to the extent not otherwise prohibited by law, upon the written request of the Company, forfeit and repay to the Company the difference between what the Participant received and what the Participant should have received based on the accounting restatement, in accordance with (i) the Company’s compensation recovery, “clawback” or similar policy, as may be in effect from time to time and (ii) any compensation recovery, “clawback” or similar policy made applicable by law including the provisions of Section 945 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the rules, regulations and requirements adopted thereunder by the Securities and Exchange Commission and/or any national securities exchange on which the Company’s equity securities may be listed (the “Policy”). By accepting an Award hereunder, the Participant acknowledges and agrees that the Policy shall apply to such Award, and all incentive-based compensation payable pursuant to such Award shall be subject to forfeiture and repayment pursuant to the terms of the Policy.

(g) Section 162(m) Transition Relief. This Plan, having been adopted prior to the Company’s securities having become publicly held in connection with an initial public offering, is intended to satisfy the requirements for the transition relief under Treasury Regulation §1.162-27(f)(1) such that the deduction limit set forth in Treasury Regulation §1.162-27(b) does not apply to any remuneration paid pursuant to this Plan until the first meeting of the shareholders of the Company at which directors of the Company are to be elected that occurs after the close of the third calendar year following the calendar year in which the initial public offering of the Company’s securities occurs.
