Unconditional Vesting

You want this if you're an employee.

You've been granted a stock option package. Usually, they vest zero the first year; then, on the first year anniversary, you get 1/4 of your total, then you vest the rest over the remainder of your total of 4 years.

But if you get fired, or if the company is sold, or whatever else happens...you get your full vest if you have this provision.
