x2titans --
I don't work for Intel, and I'm certainly not qualified to give you legal advice, but on this page:
http://osstbb.intel.com/
there is a link to an explanation of the "runtime exception" to the GPL for this library. That page contains some explanatory text that may answer your questions.
Hope this helps,

Using TBB for non open source software
I had read through GPL, but I am still not clear on the issue that whether or not non-GPL software can dynamically link to GPL librarby.
Is it legal to develop windows non-open source application which dynamically link to TBB?
