If you are laid of by WFT, I seriously doubt that they can come after you for relo costs. If they try, check with an employment lawyer before signing anything.
Being acquired is good. If the acquiring company is savvy they are going take the key people along with the assets leaving WFT to do the dirty on the people they don't want. On the other hand if they are a new player, they will take people and assets and take some time to figure out what they have... they will then consolidate and lay off the excess... with terms that can be no worse than WFT currently has
