Com. Code, § 14106

(1) If a security interest is perfected or has priority on January 1, 1976, as to all persons or as to certain persons without any filing or recording, and if the filing of a financing statement would be required for the perfection or priority of the security interest against those persons under this code, as amended by the Legislature at the 1973–74 Regular Session, the perfection and priority rights of the security interest continue until January 1, 1979. The perfection will then lapse unless a financing statement is filed as provided in subdivision (4) or unless the security interest is perfected otherwise than by filing.

(2) If a security interest is perfected on January 1, 1976, under a law other than this code which requires no further filing, refiling or recording to continue its perfection, perfection continues until and will lapse January 1, 1979, unless a financing statement is filed as provided in subdivision (4) or unless the security interest is perfected otherwise than by filing, or unless under Section 9311 the other law continues to govern filing.

(3) If a security interest is perfected by a filing, refiling or recording under a law repealed by this code as amended by the Legislature at the 1973–74 Regular Session which required further filing, refiling or recording to continue its perfection, perfection continues and will lapse on the date provided by the law so repealed for a further filing, refiling, or recording unless a financing statement is filed as provided in subdivision (4) or unless the security interest is perfected otherwise than by filing.

(4) A financing statement may be filed within six months before the perfection of a security interest would otherwise lapse. Any such financing statement may be signed by either the debtor or the secured party. It must identify the security agreement, statement, or notice (however denominated in any statute or other law repealed or modified by this code as amended by the Legislature at the 1973–74 Regular Session), state the office where and the date when the last filing, refiling, or recording, if any, was made with respect thereto, and the filing number, if any, was made with respect thereto, and the filing number, if any, or book and page, if any, of recording and further state that the security agreement, statement, or notice, however denominated, in another filing office under this code or under any statute or other law repealed or modified by this code as amended by the Legislature at the 1973–74 Regular Session is still effective. Section 9501 and Sections 9301, 9303, 9304, 9305, 9306, 9307, 9316, and 9337 determine the proper place to file such a financing statement. Except as specified in this subdivision, the provisions of Sections 9515 and 9522 for continuation statements apply to such a financing statement.
