In re MARINE OPTICAL, INC., Debtor.
FIRST NATIONAL BANK OF BOSTON, Appellant,
v.
MARINE OPTICAL, INC., Appellee.
Bankruptcy No. 80-9010.
Bankruptcy Appellate Panel, D. Massachusetts.
May 11, 1981.
Riemer & Braunstein by Charles R. Bennett, Jr., David S. Berman and Julius Thannhauser, Boston, Mass., for appellant.
Gerald Rosen, Boston, Mass., for appellee.
Before CYR, C.J., and VOTOLATO and JOHNSON, JJ.
CYR, Bankruptcy Judge.
Appeal is taken from an order authorizing the use of cash collateral. Marine Optical, Inc. commenced these voluntary chapter 11 reorganization proceedings October 21, 1980, followed by the subject motion to use cash collateral under Bankruptcy Code § 363(c)(2)(B).[1] The bankruptcy court promptly scheduled an emergency hearing for October 23, 1980 and ruled on the motion from the bench,[2] authorizing the use of cash collateral of the appellant in payment of prepetition priority wage, salary, and commission claims of employees and sales personnel employed by Marine Optical or soon to be reemployed. The bankruptcy judge determined that the interest of the appellant in the cash collateral used to satisfy prepetition priority claims was adequately protected as required by Bankruptcy Code § 363(e).[3] Appellant does not challenge *894 the adequacy of the protection accorded its interest in the cash collateral used to satisfy prepetition priority claims, but insists that the court erred in permitting a disposition of cash collateral for prepetition purposes which might jeopardize the recoverability of a potential super priority claim.[4] We are presented on this appeal with the contention that a bankruptcy court may not authorize the use of cash collateral, adequate protection notwithstanding, without further antecedent provision for the payment of whatever super priority claim may conceivably arise in the event the adequate protection previously provided proves inadequate. We view the matter somewhat differently.
Appellant is entitled to adequate protection for the use of its cash collateral[5] as determined by the court consistent with Bankruptcy Code § 361.[6] Section 507(b)[7] neither limits nor enlarges the protection required before cash collateral may be used. It establishes a statutory fail-safe system in recognition of the ultimate reality that protection previously determined the "indubitable equivalent"[8] of an interest in cash collateral may later prove inadequate. Section 507(b) superimposes no futile requirement that the court contemporaneously provide more than the adequate protection required by section 363(e). The adequacy of the protection provided appellant under section 363(e) remains unchallenged and we decline to indulge the presumption that appellant is the holder of a section 507(b) super priority claim.
Affirmed.
