11 U.S.C. Section 1221
Filing of plan
The debtor shall file a plan not later than 90 days after the order for relief under this chapter, except that the court may extend such period if the need for an extension is attributable to circumstances for which the debtor should not justly be held accountable.

(d) Notwithstanding subsection (b)(2) of this section and sections 506(b) and 1225(a)(5) of this title, if it is proposed in a plan to cure a default, the amount necessary to cure the default, shall be determined in accordance with the underlying agreement and applicable nonbankruptcy law.
