That link details a case about a loan. I was restricting my research to convertible notes since that's what seems to apply here. But I appreciate the link and it's an example of how contradictory the info is. You can study this stuff for 10 years and still have no clue how a judge would rule in this case.

"Defendant's contention that this court must declare the loan void as a matter of law is without merit. There is no specific statutory authority for voiding a loan that violates the criminal usury statute"
