Client is paranoid about Google penguin penalty from getting links from a new website they are building

[VanguardCommunications]

We have a client that is creating a new promotional website that consists of videos, brands and product reviews (SITE B).  After a visitor watches a video on SITE B they will be given a "click to purchase" option that will lead them to the original website (SITE A).

Our client is paranoid that since all the outgoing links on the new SITE B are going to the original SITE A there might be algorithm penalty (for one website or both).   I find this very unlikely and even recommend "no follow" coding for a peace of mind.  However are there any resources/links out there that can back up my argument that they will be alright?

Thanks

Penguin is a penalty that was created to flag unnatural, artificial linking where that linking was implemented purely to game the Google system.

If both site A and site B are legitimate, trustworthy sites, where the company brand is clearly consistent across both sites, and as long as the links are a "buy" link that takes the visitor to a purchase page, and where those links have anchor text that is not stuffed with keywords, then there is no reason to believe Penguin would flag either site for artificial manipulative links.

And yes, putting a nofollow on those links will ensure this is an absolute certainty.
