Most employees get hit by the AMT and the step up in basis when exercising their incentive employee stock options, and from just skimming the bill, I don't see how that is prevented.
Regardless, the Obama Administration "strongly opposes" the bill in its current form since it would "increase the Federal deficit by $1 billion over the next 10 years."

I wonder how often bills with this "strong opposition" still end up getting passed anyway.
[1] $1 billion over 10 years is $100 million per year.
