The options and RSUs will be granted by the Company’s Board of Directors pursuant to the Company’s 2010 Stock Incentive Plan (the “Plan”). The grant date of the options and RSUs will be established by the Board of Directors and the exercise price of the options will be the fair market value of the Common Stock on the date of grant.
