Should be an attachment link with the 8k announcing the Notes or attached to the 10k. I didn’t find when the warrants expired in the attachment, but it was like 150 pages long and I could have fell asleep while scanning through the document. The previous warrants expired in daily trances over a 3 month period after expiration of the notes. That is evidently how they are commonly done. I don’t know how this applies if the Notes are converted early though.
