In terms of buyout, if there is an NDA in the office he can not legally mention it in the 8K that was submitted. Unless the 8K is filed in regards of a negotiated buyout.
But in either case if the material acquired from Chem-div is worth $800K, it must be worth a lot more. This is a half way settlement, meaning both parties are right and both parties are wrong. The edge goes to Regen under patent verbiage.
GLTA here, hopefully your RGBP shares prosper you well.
