Cammie received 100 NQOs (each option provides a right to purchase 10 shares of MNL stock for $10 per share). She started working for MNL Corporation four years ago (5/1/Y1) when MNLs stock price was $8 per share. Now (8/15/Y5) that MNLs stock price is $40 per share, she intends to exercise all of her options.
