the demise of csl

Patyrs and CSL had a deal, the conditions and results of which remain highly secretive. Now we all know that CSL is big and successful, that does not however mean that it's omnificent and/or omnipotent in it's chosen field. The agreement was supposed to last initially for 30 months and began in Jan 2010. If the deal was cut short the question arises, "did they jump or were they pushed?"
Legally I believe that a confidential agreement is the property of the parties making such agreement. Therefore as the shareholders of Patrys are one of the parties they are entitles to know the details of happennings, are they not?
