RE:Skinmedica...the first milestone payment will be tied to the first commercial sale of each product in a certain geographic market. For example if they launch a skin lightener cream in the US that will be a milestone payment plus a royalty on the sale. If they launch in Canada at the same time, that's another milestone payment and the royalties also start at the point. If they launch a crme and a serum (for example) that's two separate milestone payments.
