The fact is, that at this point we don't know when the agreement(s) will expire, it could be when the patents do, or much longer.

I have to disagree. As murgirl1 posted from the 10Q,

"In December 2009 we licensed and settled with one defendant that agreed to make a lump sum payment in November 2010 for past infringing sales through December 31, 2009 and to pay an annual royalty for any on-going sales that practice our U.S. Patent 5,491,774, until its expiration. "

This clearly says the annual royalty [with Wolverine] will end when the '774 patent expires. There's no other way it can be interpreted. Perhaps other agreements will be structured differently; we'll have to wait and see.
