presents significant and unique opportunities to move vertically and/or horizontally to improve your situation

If you are better paid than the existing employees it's actually more likely that your salary will be frozen until it "harmonises" with them. You are also unlikely to have the contacts at the acquirer for an interesting lateral move, even if its permitted in the terms of the acquisition, I think the last time we were told there would be no internal transfers for the first two years.
