An individual who receives educational assistance under the scholarship program under this chapter shall repay to the Secretary an amount equal to the unearned portion of such assistance if the individual fails to satisfy the requirements of the agreement entered into under section 7504 of this title, except in circumstances authorized by the Secretary.

The Secretary shall establish, by regulations, procedures for determining the amount of the repayment required under this section and the circumstances under which an exception to the required repayment may be granted.

An obligation to repay the Secretary under this section is, for all purposes, a debt owed the United States. A discharge in bankruptcy under title 11 does not discharge a person from such debt if the discharge order is entered less than five years after the date of the termination of the agreement or contract on which the debt is based.
