Mike, Material definitive agreements can be the toughest filings to make the "to file or not to file" call on because of the subjective nature of materiality. My guess is that the SEC wouldn't have blinked if they didn't file the royalty agreement. From the company's perspective the decision is easy: If it can be perceived as good news, file. One can only speculate as to whether the filing would have been made had an agreement of similar value been made with an entity that offered less promotional value.
