I won't go into detail about Marr, but basically they hold about 15-20% ownership in Calypte, financed some credit facilities with Calypte, and also went into a joint venture together in China.
Last we heard Calypte was still in default of the debt agreements arranged with Marr. The 2009 10K mentioned that they are in current discussions and working on an agreement with Marr to restructure the debt by handing over equity interests in their 2 Chinese endeavors (Beijing Marr and Beijing Calypte) and other Marr interests to a third party investor. There was a non-bonding agreement put into place, but no final definitive agreement. The timeline was set for 6/21/2010 if final agreements could be made.
We have not heard any update on this yet.
Basically Calypte is a long, long shot...so only put into it what you can afford to lose because there is a decent chance this will go to zero. However, if things do turnaround and they gain any market traction...we could be looking at a .10-.20 stock price. JMO.
