Maybe I'm mistaken, but I believe you only have 90 days after leaving a company to purchase vested options. I may be wrong, however.

To my knowledge, stock options are usually granted as ISO which have the 90 day cap. If they get converted to NSO, the cap can be longer but tax treatment is different.

Mine have a 2016 expiration date. It just depends on the grant agreement.

Be careful, there are laws which govern this, not just the grant agreement. Caveat emptor.
