From my really quick glance at the last 10q, I believe there was one note that just matured on Jan 18th valued at $37,500 and another note due to mature on Feb 9th valued at $32,500. Besides these I don't think there is anything maturing until May, I think?
I don't know if the Jan18th one has been converted yet or not. Maybe ppl here can shed some light on this. And if anyone this information is not correct, feel free to correct me. Thanks!
