Extending an Open Ended Loan

[Mike Hartzog]

Has anyone done an extension on an open ended loan?  I am familiar with the concept, but not so much with the nuts and bolts of how to get it done.  I believe there needs to be a new note and security instrument.  Not sure what other docs are required and how to record it so that it shows up as an extension rather than a net new lien.  Any insight is appreciated.
