Yes, it's definitely not easy to live, all the more as you don't have all the insights and aren't sure to know/understand everything at stake.
I suspect that if you are part of the deal, if you wanted to work for the acquiring company, you could have already gotten a job there long ago. Clearly they were not your first choice of places to work. The terms that are being offered don't change that, and perhaps no terms can.
That's o.k.
