This seems to be BSD-like to me. There is condition that I dislike,
because it doesn't have an obvious meaning (a clause similar is often
seen on scientific packages):

5. Due credit should be given to the ExoLab Group (http://www.exolab.org).

It doesn't explain when credit is "due", how credit should be given.
Is it for the use, the redistribution, both? I don't think this is a
blocker, though. My interpretation is that having this license in the 
package is enough.
