Best contact the company, however, I think you will find they have an exercise price of 27 cents. Not much interest in the OB's, some clown buys a few at 5 / 6 cents every now and again. Crossed my mind to buy a few @ 0.001 and flog them at say 4 / 5 cents just for a laugh.
VAN needs income to cover the interest costs on it's outstanding loans atm....until that happens - buyer beware IMO
