Yes. No. So let me be clear on that, we're not going to give projections around that. And these collaboration agreements, I want to make sure everyone understands, our feasibility studies, so it's basically, a, number one, making sure that our drug works -- excuse me, our -- their drug works in our Durasert formulation, that's number one. Number two, in some cases, we move into animal studies and then it's making sure that we get positive results from the animal studies. Should those -- all those data in any one of the collaborations be positive, then we would move into a broader, what I would call, more typical and robust collaboration agreement before you move into human clinical studies. As to revenues and royalties, et cetera, in our agreements, we typically have -- most of the money is paid upfront because they're covering our costs to produce the devices, run the initial studies and PK data. So what you've seen is that we will receive, and I think Len referenced that, $750,000 will show up in the next quarter from our agreement with our major pharmaceutical partner -- cash, excuse me, thank you. And right now, unless we get others struck, we'll have very, very, very modest additional milestones because most of these gets paid upfront.
