I'd look negotiate getting a signing bonus as a new hire that covered whatever you would be getting from VMware if you were laid off in November + the salary until there minimum for starters. And RSUs (which can be how they pay you the signing bonus).
If you think you could go to this company and stay for at least one year or up to when the market gets better, and if the work will give you new skills and is in an area that is hot, you would be employed and able to negotiate well for your next job if you want to jump ship. I think negotiating once laid off when the merge is done or even while we are going through it is harder because the recruiters assume we are desperate. And the market is not looking good right now.
But it's a very personal decision so I wouldn't want to tell you what to do. I just gave you some pointers and things to think about.
Good luck.
