The most likely scenario IMO is that Citibank extends the loans and KD provides the same guarantee.  And for that, he would get more warrants, a "guarantee fee", pledges of "tax losses and pools" and perhaps other patents (if there are any that haven't already been pledged to him) , i.e., all the same stuff he got for guaranteeing the prior loans.  I see no reason Citibank wouldn't extend the loans if KD is guaranteeing them.
