1. (1) The lien of a mortgage and its priority shall not be affected by provisions in the mortgage instrument or in the note or other agreement evidencing the obligation that the mortgage secures, or by the exercise of such provisions by the mortgagee:

   1. (a) which provide for the renegotiation or adjustment of the interest rate at designated intervals, the effect of which may be to increase or decrease the number of periodic payments to be made, or extend or shorten the terms of payment, or both; or

   2. (b) which results in an increase in the underlying mortgage obligation during a portion of the designated term of the mortgage because of deferment of all or a portion of interest payments and the addition of such payments to the outstanding principal balance of the mortgage.

      The mortgagee may issue new notes at designated intervals during the term of the mortgage to reflect the modifications described herein.

2. (2) The provisions of subsection (1) of this section shall apply where the terms of the obligation provide that the interest rate, payment terms, or balance due on the loan may be indexed, adjusted, renewed or renegotiated and the mortgage instrument received for recordation discloses that fact.
3. (3) As used in this section, the term "mortgage" includes deed of trust.
