Seems like you should have been fully vested from any original grants by now. So, 8 year vesting, plus the low salary? Hope you are learning things that will position you for success in your next role.
At least I really hope that's the case, because an 8 year vesting schedule is idiotic.
So, can we assume some portion of the options was granted more than a year ago, and has vested already?
Your compensation is quite low, I would suggest negotiating now for a higher (market rate) salary and them making you whole after their next raise.
This whole situation has tax implications that could turn out badly for you in some scenarios, so you may need the money from that extra income to deal with that.
