(2) Any deed, deed of trust, mortgage or other instrument or document utilized in connection with any transaction arising under or affected by this article may contain provisions related to any emergency rule promulgated under this section and any extension or amendment thereof and shall, to the extent the instrument or document so provides, fully bind and be enforceable by the parties thereto as if such rule had been properly made effective under law and whether or not such rule thereafter expires or is revoked: Provided, That no such provision or agreement under this subdivision shall suspend the provisions of this article or exceed its limitations.
