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

the Employee’s place during any period of Disability suffered by the Employee during the Employment Period. Notwithstanding any such designation, the Employee shall continue to receive the Employee’s 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
shall first occur. 
 4.3 Disability Income Payments. While receiving disability income payments under the Company’s
disability income insurance (if any), the Employee shall not be entitled to receive any Base Salary under Section 3.1, but shall continue to participate in all other compensation and benefits in accordance with
Section 3.3 until the date of the Employee’s termination of employment. 
 4.4 Verification of
Disability. If any question shall arise 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 shall arise and the Employee shall fail to submit to such medical
examination, the Company’s determination of the issue shall be binding on the Employee. 
 5. TERMINATION FOR CAUSE BY THE COMPANY.
The Company may terminate the employment of the Employee hereunder at any time during the Employment Period for “Cause” (such termination being hereinafter referred to as a “Termination for Cause”) by giving the

expected to result in a material loss to the Company or any of its Affiliates;

	 	(v)	 the Employee’s material failure to perform or substantial negligence in the performance of the Employee’s obligations and duties to
the Company or any of its Affiliates, or any misconduct, dishonesty or acts of moral turpitude by the Employee which is or could reasonably be expected to be materially detrimental to the interests and well-being of the Company or any of its
Affiliates, including, without limitation, harm to its business or reputation.
