(2) in a case in which the last payment on the original payment schedule for a claim secured only by a security interest in real property that is the debtor's principal residence is due before the date on which the final payment under the plan is due, the plan may provide for the payment of the claim as modified pursuant to section 1325(a)(5) of this title.
(d) The plan may not provide for payments over a period that is longer than three years, unless the court, for cause, approves a longer period, but the court may not approve a period that is longer than five years.
(e) Notwithstanding subsection (b)(2) of this section and sections 506(b) and 1325(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.
