Not sure what you are asking but the strike price is the exercise price. You either pay 6.5c before june 30th and get the same number of head shares or you let the options lapse and lose whatever you paid for the options. If you purchased the options today or yesterday I think you would have paid 0.2c or $0.002 per option not 2.0c.
assuming that's what you meant then any price above 6.7c after expiry means you have made money ( after you have sent a chq in before june 30th for $16250.00)
If you sell the options before june 30th for $0.01 then you make $2000.00
If you convert the options and sell the heads for say $0.075 after june 30th then you have also made $2000.
The difference is that the options have greater leverage and thus a premium if the expectation is for heads to price up well beyond 6.5c in the next month or so. if you don't believe that this will happen in the short term but have an expectation of 6.5c + in a longer term (and past june 30th) then start buying heads now at 5.2c
