    (a) Notwithstanding section 28(1)(e) of this act, the department shall not assess any tax, delinquency for a tax, penalty, or interest covered under the agreement for any period before the lookback period identified in the agreement.

    (b) The department shall not assess any applicable discretionary or nondiscretionary penalties for the lookback period.

    (c) The department shall provide complete confidentiality of the agreement and shall also enter into an agreement not to disclose, in accordance with section 28(1)(f), any of the terms or conditions of the agreement to any tax authorities of any state or governmental authority or to any person except as required by exchange of information agreements authorized under section 28(1)(f), including the international fuel tax agreement under chapter 317 of title 49 of the United States Code, 49 USC 31701 to 31707.

    (10) Nothing in subsections (2) to (9) shall be interpreted to allow or permit unjust enrichment as that term is defined in subsection (15). Any tax collected or withheld from another person by an applicant shall be remitted to the department without respect to whether it was collected during or before the lookback period.
