Ask HN: How do you evaluate a stock tender offer?

I have to evaluate a tender offer for private stock from a previous employer with a deadline coming up. I have some updated financial statements but have no idea if this is fair or not. On the one hand, it would be smart to diversify since it’s decent sum of money in the “SF house money” size. On the other hand, it would suck if the shares were actually worth much more and sold prematurely.
