Secured creditor sought allowance of administrative expense against the bankruptcy estate pursuant to 11 U.S.C. section 503.  The Court denied the creditor's motion because: 1) it was a prepetition creditor, 2) it never offered proof that Debtor disposed of the collateral in its capacity as debtor-in-possession, 3) it did not prove the value of the collateral, and 4) it did not demand adequate protection.
