No licensee authorized to engage in the consumer loan business shall directly or indirectly charge, contract for, or receive any interest, discount, or consideration greater than the licensee would be permitted by law to charge if he were not a licensee under this act upon the loan, use, or sale of credit, of the amount or value of more than $50,000. The foregoing prohibition shall also apply to any licensee who permits any person, as borrower or as endorser, guarantor, or surety for any borrower, or otherwise, to owe directly or contingently or both under one or more loan contracts to the licensee at any time the sum of more than $50,000 for principal.
