6.6. Employee shall not be entitled to receive the Severance Payment or Change of Control Severance Payment unless and until Employee executes, and does not revoke as permitted by law, a release in a form reasonably acceptable to the Company that unconditionally releases, waives, and fully and forever discharges the Company and its past and current shareholders, directors, officers, employees, and agents from and against any and all claims, liabilities, obligations, covenants, rights, demands and damages of any nature whatsoever, whether known or unknown, anticipated or unanticipated, including without limitation, any claims relating to or arising out of Employee’s employment with the Company, claims arising under the Age Discrimination in Employment Act of 1967, as amended, Title VII of the Civil Rights Act of 1964, as amended, or the Civil Rights Act of 1991, or claims arising under the applicable state fair employment laws, but excluding any rights of Employee under any remaining stock option agreements (if any) or other agreements relating to equity in the Company and Employee’s right to indemnification from the Company in respect of his services as a director, officer or employee of the Company or any of its Affiliates. The release shall also contain customary non-disparagement covenants by Employee. Employee’s right to receive the Severance Payment or Change of Control Severance Payment is conditioned upon Employee’s performance of the obligations and covenants contained in this Employment Agreement, the Covenants Agreements (as defined below) and any other agreement between Employee and the Company. In the event of any material breach of any such obligations during or after payment of the Severance Payment or Change of Control Severance Payment, the Company may cease to make any remaining payments.

6.7. Notwithstanding anything in this Agreement to the contrary, all payments to be made upon a termination of employment under this Agreement will only be made upon a “separation from service” within the meaning of Section 409A of the Internal Revenue Code of 1986 (the “Code”). To the maximum extent permitted under Section 409A of the Code and its corresponding regulations, the cash severance benefits payable under this Agreement are intended to meet the requirements of the short-term deferral exemption under Section 409A of the Code and the “separation pay exception” under Treas. Reg. §1.409A-1(b)(9)(iii). For purposes of the application of Treas. Reg. § 1.409A-1(b)(4)(or any successor provision), each payment in a series of payments to Employee will be deemed a separate payment. In addition, to the extent compliance with the requirements of Treas. Reg. § 1.409A-3(i)(2) (or any successor provision) is necessary to avoid the application of an additional tax under Section 409A of the Code to payments due to Employee upon or following his “separation from service”, then notwithstanding any other provision of this Agreement (or any otherwise applicable plan, policy, agreement or arrangement), any such payments that are otherwise due within six months following the Employee’s “separation from service” will be deferred without interest and paid to Employee in a lump sum immediately following such six month period. This paragraph should not be construed to prevent the application of Treas. Reg. § 1.409A-1(b)(9)(iii) (or any successor provision) to amounts payable hereunder. For purposes of the application of Section 409A of the Code, each payment in a series of payments will be deemed a separate payment.

7.Noncompetition; Nonsolicitation; Confidential Information, etc.

7.1. Employee acknowledges and agrees that Employee is bound by the Employment Non-Competition Agreement entered into at his commencement of employment (the “Non-Competition Agreement”), which shall continue in full force and effect.

7.2. Employee acknowledges and agrees that Employee is bound by the Employee Nondisclosure and Business Ideas Agreement dated as of Employee’s commencement of employment (together with the Non-Competition Agreement, the “Covenants Agreements”), which shall continue in full force and effect.

8.Indemnification. Subject to the Company’s Articles of Incorporation and Bylaws, the Company shall indemnify Employee to the fullest extent permitted by law against all costs, expenses, liabilities and losses (including, without limitation, attorneys’ fees, judgments, fines, penalties, and amounts paid in settlement) reasonably incurred by Employee in connection with any “Proceeding” (as defined herein). For the purposes of this Section 8, a “Proceeding” shall mean any action, suit or proceeding, whether civil, criminal, administrative or investigative, in which Employee is made, or is threatened to be made, a party to, or a witness in, such action, suit or proceeding by reason of the fact that he is or was an officer, director or employee of the Company or is or was serving as an officer, director, member, employee, trustee or agent of any other entity at the request of the Company.

9.Golden Parachute Tax Provisions.

9.1. In the event that the Company or any of their Affiliates undergoes a Change of Control prior to the time that it (or any Affiliate that would be treated, together with the Company, as a single corporation under Section 280G of the Code and the regulations thereunder) has stock that is readily tradeable on an established securities market (within the meaning of the Section 280G of the Code and the regulations thereunder), if the payments or benefits provided under this Agreement, either alone or together with other payments or benefits which Employee receives or is entitled to receive from the Company or any of its Affiliates, would constitute an “excess parachute payment” within the meaning of Section 280G of the Code, the following provisions shall apply:

9.1.1. The Company or any of applicable Affiliates will cooperate in good faith with Employee such that any such payments or benefits will not be deemed an “excess parachute payment” within the meaning of Section 280G of the Code.

9.1.2. In the event that any payments or benefits (whether payable pursuant to this Agreement or otherwise) to Employee could be exempt from Section 280G of the Code if the shareholder approval requirements under Section 280G(b)(5) of the Code and the regulations thereunder were met, such payments will be conditioned on shareholder approval in accordance with Section 280G(b)(5)(B) of the Code and regulations thereunder and the Company or any of its applicable Affiliates agrees to use best efforts to seek to obtain such shareholder approval. The actions of the Company or any of its applicable Affiliates pursuant to this provision are not intended to bind, nor shall be construed as binding, the shareholders of the Company or any of its applicable Affiliates.

9.2. In the event that the Company or any of its applicable Affiliates undergoes a Change of Control at such time that it (or any Affiliate that would be treated, together with the Company, as a single corporation under Section 280G of the Code and the regulations thereunder) has stock that is readily tradeable on an established securities market (within the meaning of the Section 280G of the Code and the regulations thereunder), if the payments or benefits provided under this Agreement, either alone or together with other payments or benefits which Employee receives or is entitled to receive from the Company or any of its applicable Affiliates, would constitute an “excess parachute payment” within the meaning of Section 280G of the Code, Employee shall be entitled to receive (i) an amount limited so that no portion thereof shall fail to be tax deductible under Section 280G of the Code or subject to an excise tax under Section 4999 of the Code (the “Limited Amount”), or (ii) if the amount otherwise payable hereunder together with other payments or benefits which Employee receives or is entitled to receive from the Company or any of its applicable Affiliates (without regard to clause (i)) reduced by all taxes applicable thereto (including, for the avoidance of doubt, the excise tax imposed by Section 4999 of the Code) would be greater than the Limited Amount reduced by all taxes applicable thereto, the amount otherwise payable hereunder together with other payments or benefits which Employee receives or is entitled to receive from the Company or any of its applicable Affiliates.

10.In the event that any payments under this Agreement or otherwise are required to be reduced as described in this Section 9, the adjustment will be made, first, by reducing the cash severance, if any, due to Employee pursuant to Section 6; second, if additional reductions are necessary, by reducing the payments due to Employee under Section 6.5(C) (Target Bonus) and third, if additional reductions are still necessary, by eliminating the accelerated vesting of equity-based awards, starting with those awards for which the amount required to be taken into account under the Section 280G of the Code rules is the greatest; provided, that in all events, such reductions shall be done in a manner consistent with the requirements of Section 409A of the Code, to the extent applicable.
