You agree that the obligations in Section 4, together with your other obligations under this Agreement, are reasonably necessary for the protection of the Company’s proprietary interests, and you acknowledge and agree that your obligations contained in this Agreement will not preclude you from becoming gainfully employed in a similar capacity, following a termination of your employment with the Company, given your training, general knowledge and experience.

Termination

Resignation: If for any reason you should wish to leave the Company, you will provide the Company with three (3) months prior written notice of your intention (the “Resignation Period”). The Parties hereby agree that in order to protect the Company’s interests, the Company may, in its sole and unfettered discretion, waive the Resignation Period and end your employment immediately by delivering to you a written notice followed by payment of your Base Salary due to you during the remainder of the Resignation Period.

Termination for Cause: The Company may terminate your employment at any time for Cause, effective upon delivery by the Company to you of a written notice of termination of your employment for Cause. You will not be entitled to receive any further pay or compensation (except for pay, if any, accrued and owing under this Agreement up to the date of termination of your employment), severance pay, notice, payment in lieu of notice, benefits or damages of any kind, and for clarity, without limiting the foregoing, you will not be entitled to any bonus or pro rata bonus payment that has not already been awarded by the Company.

Termination Without Cause: The Company may terminate your employment without cause at any time upon providing you with severance equal to base salary- for a period of 6 months plus an additional month for every year of service rendered to the Company, up to a maximum of 12 months.

Garden Leave: Once notice of resignation or termination has been given by you or the Company, the Company may excuse you from the performance of your duties and/or exclude you from any premises of the Company or any Affiliated Company. Base Salary and other contractual benefits shall continue to be paid or provided to you until the last day of the notice period, subject to the terms of the governing agreements or plans. During any period where you are excused from your duties and/or excluded from the Company’s premises, you shall not, without the prior written consent of the Company, contact (either directly or indirectly) any clients, customers, suppliers or employees of the Company or any Affiliated Company. At any time, the Company may require you to return to the Company all property in your possession or under your control belonging to the Company or any Affiliated Company.

No Implied Entitlement: Other than as expressly provided herein, you will not be entitled to receive any further pay or compensation, severance pay, notice, payment in lieu of notice, incentives, bonuses, benefits or damages of any kind.

Continued Effect: Notwithstanding any changes in the terms and conditions of your employment which may occur in the future, including any changes in position, duties or compensation, the termination provisions in this Agreement will continue to be in effect for the duration of your employment with the Company unless otherwise amended in writing and signed by the Company.

Authorization to Deduct Debts: If, on the date you leave employment, you owe the Company any money, you hereby authorize the Company to deduct any such debt from your final salary payment or any other payment due to you.
