Re: Incentive Stock Option


 


Notice is hereby given pursuant to Section
3 of my Agreement that I elect to purchase the number of shares set forth below at the exercise price set forth in my Agreement:


 


	Stock Option dated:	 	 
	 	 	 
	Number of shares being purchased:	 	 
	 	 	 
	Option Exercise Price Per Share	 	 
	 	 	 
	Aggregate Option Exercise Price	 	 


 


A check in the amount of the aggregate price
of the shares being purchased is attached.


 


I understand that the shares of Common Stock
that I receive upon exercise of my Option may not be freely tradable.


 


Further, I understand that, as a result of
this exercise of rights, I will recognize income in an amount equal to the amount by which the fair market value of the shares
of Common Stock exceeds the exercise price. I agree to report such income in accordance with then applicable law and to cooperate
with the Company in establishing the withholding and corresponding deduction to the Company for its income tax purposes.


 


I agree to provide to the Company such additional
documents or information as may be required pursuant to the Company’s 2014 Equity Incentive Plan.
