Recently, I received an offer for an executive position at a large firm. I work in the tech industry in Silicon Valley.

On the whole, I'm happy with the proposed job and compensation, benefits etc.

However, they want to to close out my interest in several companies I've built. I'm also not allowed to take on any independent outside projects (even though there is no outside conflict of interest). 

Their justification is that they want my "undivided attention". How common is this at the executive level? It seems that virtually everyone I speak to has other obligations and as long as their no conflict of interests and they do it on their own time there is no issue. That is also currently the practice at my current place of employment.

Is this more common in some parts of the country than others? Is this common everywhere at higher levels? I'm trying to get the lay of the land as to what to expect.

Thanks!

**Edit:** On the whole they have been accommodating of other requests, for example location, etc.

I am curious how people suggest handling this type of situation and if they have seen it before did they end up signing or rejecting?
