(9) the value of any goods received by the debtor within 20 days before the date of commencement of a case under this title in which the goods have been sold to the debtor in the ordinary course of such debtor’s business.
(c) Notwithstanding subsection (b), there shall neither be allowed, nor paid—
(1) a transfer made to, or an obligation incurred for the benefit of, an insider of the debtor for the purpose of inducing such person to remain with the debtor’s business, absent a finding by the court based on evidence in the record that—
