That's brutal. "engage in any employment, business or activity that is competitive with the Company's businesses"

There aren't many tech companies that can't be said to be competing with Google in one way or another. Assuming "the Company" means Google rather than Doubleclick (and it must) that makes them nearly unemployable.

"solicit business from, do business with or render services to, in any capacity, directly or indirectly, any entity that is or was a Company client or customer within the last twelve months of my employment with the Company, for a purpose or in a manner that is in any way competitive with the Company's business."

i.e., can't sell ads to anyone who used AdSense?

This is incredibly evil.
