General Electric Cap. v. Future Media Productions, 536 F.3d 969 (9th Cir 2008)
    Where creditor’s oversecured claim was paid in full out of the proceeds of an asset sale, rather than pursuant to a chapter 11 plan, and thus not subject to the “cure” provisions of § 1124 that a chapter 11 plan would allow, creditor was entitled to a default rate of interest.  Court distinguishes the holding in In re Entz-White Lumber and Supply, Inc., 850 F.2d 1338 (9th Cir. 1988), and disapproves of the holding in In re Casa Blanca Project Lenders, 196 B.R. 140 (9th Cir. BAP 1996)
