Granulocytes, specifically neutrophils, help the body fight bacterial infections. The number of granulocytes in the body usually increases when there is a serious infection. People with a lower number of granulocytes are more likely to develop bad infections more often.
Congrats on a sick trade. If the buyout happens before the options expiration, you can exercise your options for stock, purchase the stock at $28.00, and sell the shares for $40.00 and make $12.00 per share (less the price of the options). Realistically, the value of the call option will go up to $12.00+ and you can just sell the option.
Instead of a date, another right-to-acquire option might be a trigger event such as a change of control of the firm. In this case, change of control is merely a fancy term for the acquisition of your company by another firm. Entrepreneurs love this kind of vesting option. And why not. Let's say you have been granted 10,000 options with a stock price of $3.50 per share. If the terms of your stock option grant indicate that they fully vested at change of control and another firm acquires your firm at $4.00 per share, your options immediately vest at the closing of the acquisition.
