Yes, but that was the objective, wasn't it?

Absolutely. And the big thing that had happened in this year is that both leukocyte interferon and fibrobast interferon have been cloned, the leukocyte by the Weissman group - that Schering has an interest in. Schering is going to make that kind of interferon -- and the other by Hoffmann-LaRoche, who is going to make fibroblast and leukocyte. This is really light years ahead of where we were a year ago. It could have taken another two or three years to do this. We had no way of knowing. We knew that eventually it would be done, but we didn't know it would happen quite so soon.

No, but both Schering and Hoffmann-LaRoche are
