Following entry of order confirming sale of Chapter 11 debtors' assets to insider used as stalking horse, debtors filed supplemental motion for assumption and assignment of trade-back agreements allegedly included in assets sold. The court held that (1) insider used as stalking horse in connection with sale of debtors' assets did not pay anything for trade-back agreements which it later claimed to have purchased as part of its total bid of $51 million, so that motion to assume and assign such agreements to insider would not be approved as not being in best interests of estate; and (2) options which debtors had pursuant to terms of trade-back agreements with company from which they acquired refrigerated trucks, to require company to buy trucks back at price equal to 55 percent of original purchase price, were in nature of "executory contracts," that debtors could assume and assign.
