If you have to pay a fee to get listed in a directory, then some might consider that to be a purchased link.
This has been an area of confusion for a long while - no matter how much Google publicizes their viewpoint. Here's my understanding:
If the website is paying for editorial staff to review the site - and therefore the entry can still be turned down if it's not up to editorial standards - that is NOT considered a paid link. If the directory accepts every site that pays them, then that IS considered a paid link.
