Backlinks on Parking Pages

I was recently asked to create a parking page for my companies 500+ domain names. All they required of me was to make sure there was adsense.

Of course I jumped at the opportunity to instantly have those 500+ backlinks.

My question is, how will google percieve the huge increase of backlinks from these parked domains?

I wouldn't want to hurt my companies by google looking at it as backlink spam. Thanks!

just do it gradually, and make sure you link to relevant sites
