Hi bb1webs,
I had a look at Expekt and looked at what cookies are being written. All but one come from Expekt. The other one comes from a third party site that measures conversions and tracking for Expekt. I am sure that there is nothing to worry about in terms of Expekt as they are a solid company.
You can always go directrly to their affiliate site for more info:

Hope that helps,
Raphael
