To specify what is in part 6, it spells out what a debt obligation is, what sort of certificate is required to create one, what kind of record-keeping the corporation is required to do, how you transfer debt obligations from one person to another—because some of these are traded on the stock exchange.
These are fairly common. If they are transferred and there is some difficulty with the transfer concerning whether it is valid or not; or if the person who signed it is somebody who has since resigned or been fired from the company, is the certificate still good, although the signature has changed? They are very detailed, technical issues, but the general concept behind them is to allow a regime for these things to be traded and transferred.
