I haven't seen a definitive number as to how many warrants are yet to be exercised, but I'm guessing there's not much room left once they hit the billion mark. LP et. al., cannot exercise without giving a 60 day notice to (someone in the company, can't remember who), but the way they wordcraft everything, I think it doesn't necessarily mean that they will give public notice of their intention. Of course, once LP exercises, it has to be disclosed.
