vesting shall accelerate as to 100% of the shares upon a change in control of the Company. The exercise price shall be the closing price of our common stock on the date of grant. 

The foregoing share amounts shall be automatically adjusted in the event of any stock split, reverse stock split, stock dividend,
recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event effecting our common stock, or any distribution to holders of our common stock
