I have definitely seen examples of Google not passing PageRank through obvious advertising links, even though the advertising site isn't using nofollow.
However, that is only a comment about the target of the link. Whether Google might penalize the site that HOSTS the link is another question completely. They certainly might.

Any alternatives to "no follow"?

You can first send the user's click to a script that then redirects to the advertiser. This is something a lot of sites do to verify how much traffic they are actually sending to each advertiser.
In addition to implementing the script, you would disallow crawling of the script's directory. Important note: have the disallow rule in place a few days before you change any links. In other words, make sure googlebot gets the new robots.txt first, or else it may get the scripts and analyze them anyway.

It's not rocket science. Google first identifies an ad section on your site and then does not trust any link within that section. If you have links without nofollow in that section they count against you.
Identifying ad sections is relatively easy, especially if it's from a known service, but even if you write the ads yourself and rotate them that *section* of your page repeats on other pages ... and what repeats is of no value.
