"Could be a licensee has a pending public offering that will provide additional revenues from which they plan to pay the license fee. PDS might agree to a contingency based on that situation being completed for some of the fee."

You might argue that you should have used "funds" instead of revenues. However, a license would never be written with the contingency being the licensee complete a public offering, that just wouldn't make sense. So it would seem that you are stating that the "revenues" would be a factor in calculating the licensing fee.
