Here's the gist:
"Under the House measure, employers with payrolls exceeding $400,000 a year would have to provide health insurance or pay the 8% penalty. Employers with payrolls between $250,000 and $400,000 a year would pay a smaller penalty, and those less than $250,000 would be exempt. Certain small firms would get tax credits to help buy coverage."
