How do I search for memberships that DO NOT have an expiration date?

The question is: How do I search for all memberships that do not have an expiration date? Here's the background info, in case it helps: our current memberships last one year, but I have about 100 or so legacy members with no expiration date. I'm trying to find them, add them to a list, and batch update them as expired. I know how to batch update membership status. The difficulty at this point is getting all target members on one list without manually adding each one.
