>Since, ...BBM is willing to undertake a tender offer at a cash price of U.S. $0.60 per share... I guess the BBMO stock is worth around $0.30 a share.<
Maybe. At this point, the tender offer at $0.60 is merely a threat; it remains to be seen if BBMO is willing to carry it out.
If you take the tender-offer threat at face value, the implied value of BBMO shares is (.60-.50)/.375=0.27.
