Employment. You and Company desire to enter an employment relationship by means of this Agreement. Company, hereby employs you subject to the terms hereof, and you hereby accept such employment upon such terms as of the Effective Date.

Confidentiality. Employee recognizes that the Company has expended and will continue to expend substantial time, money and effort in developing formulas, patterns, designs, compilations, programs, devices, methods, techniques, processes, training, intellectual property, and general knowhow that derive independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use, which is the subject of efforts that are reasonable under the circumstances to maintain its secrecy. Company possesses valuable information, including information about customers, dealers and suppliers, and among other things, about their technical problems and needs, purchasing habits, and procedures, all resulting in a great deal of customer goodwill. Company owns financial records, contracts, marketing and strategic plans, intellectual property, and other valuable information. For purposes of this Agreement, all such items and information, as well as the information defined as “Confidential Information” in the CONFIDENTIALITY, INVENTION ASSIGNMENT, NON-SOLICITATION AND NO-HIRE AGREEMENT (“Confidentiality Agreement”) (required to be executed by you concurrently herewith) are owned by Company and hereafter referred to in this Agreement as “Trade Secrets and Confidential Information.”

You will, in the course of your employment, be personally entrusted with and exposed to Company’s Trade Secrets and Confidential Information.

Company, during the term of this Agreement and after its termination, will be engaged, throughout the world, in the highly competitive Healthcare industry, in which many firms, including Company, compete.

You could, after having access to Company’s Trade Secrets and Confidential Information, become or be employed by a competitor.

Company will suffer great loss and irreparable harm if you were to separate your employment and thereafter participate, directly or indirectly, as a consultant, employee, manager, officer, director or in any other capacity in any business or venture in competition with Company, or if you at any time (during or after your employment) disclose Company’s Trade Secrets and Confidential Information.

Section 409A.

This Agreement is intended to comply with Section 409A of the Internal Revenue Code of 1986, as amended, and any applicable regulations thereunder (“Section 409A”), or an exemption thereunder and shall be construed and administered in such a manner. For purposes of Section 409A, Employee’s right to receive any installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments, and each payment made under this Agreement shall be designated as a separate payment within the meaning of Section 409A. Any payments to be made under this Agreement upon a termination of employment will only be made on a “separation from service” within the meaning of Section 409A. Notwithstanding the foregoing, if any payment or benefit provided to Employee in connection with a termination of employment is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A and Employee is determined to be a “specified employee” as defined in Section 409A(a)(2)(B)(i) of the Code, then such payment or benefit will not be paid until the first payroll date to occur following the six-month anniversary of such termination or, if earlier, on Employee’s death (the “Specified Employee Payment Date”). The aggregate of any payments that would otherwise have been paid before the Specified Employee Payment Date will be paid to Employee in a lump sum on the Specified Employee Payment Date and thereafter, any remaining payments will be paid without delay in accordance with their original schedule.

Notwithstanding the above, the Company makes no representation that the payments and benefits provided under this Agreement comply with Section 409A, and the Employee acknowledges and agrees that (i) the Employee is solely responsible for any and all obligations arising as a result of the tax consequences associated with any payment under this Agreement, including without limitation, any taxes, interest or penalties associated with Section 409A, (ii) Employee is not relying upon any written or oral statement or representation the Company, any entity affiliated with the Company, or any of their respective employees, directors, officers, attorneys or agents regarding the tax effects associated with the execution of this Agreement, and (iii) in no event will the Company be liable for all or any portion of any such obligations that may be incurred by the Employee on account of non-compliance with Section 409A or otherwise in connection with this Agreement or any payment under this Agreement.

Section 280G. Notwithstanding any other provision of this Agreement or any other plan, arrangement or agreement to the contrary, if (1) Employee is a “Disqualified Individual” (as defined in Section 280G of the Internal Revenue Code of 1986, as amended, and any applicable regulations thereunder (“Section 280G”)) and (2) any of the payments or benefits provided or to be provided by the Company or its affiliates to Employee or for the Employee’s benefit pursuant to the terms of this Agreement or otherwise, individually or together with any other payments which Employee has the right to receive from the Company, would constitute a “parachute payment” within the meaning of Section 280G (the “Parachute Payment(s)”) and would, but for this Section 24, be subject to the excise tax imposed under Section 4999 of the Code (or any successor provision thereto) or any similar tax imposed by state or local law or any interest or penalties with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the “Excise Tax”), then the total amounts received by Employee from the Company which constitute Parachute Payments shall be reduced in a manner determined by the Company that is consistent with the requirements of Section 409A to an amount equal, in the aggregate, to one dollar ($1.00) less than three (3) times the Employee’s base amount within the meaning of Section 280G, so that no portion of the Parachute Payments received by Employee shall be subject to the Excise Tax, if and only if such reduction produces a better net after-tax position (taking into account any applicable Excise Tax and any applicable income tax) than if the total payments owed to Employee were paid in full and subject to the tax.
