A secured party who has a security interest in an uncertificated security (paragraph (b) of subdivision (1) of Section 8102), which security interest attached to that uncertificated security (a) prior to January 1, 1985, or (b) after that date in an uncertificated security issued in respect of a security in which the secured party had the pre-January 1, 1985, security interest, shall not be required to take any action under Division 8 (commencing with Section 8101) to protect, preserve, or perfect that security interest, which shall remain attached and perfected to the same extent it was prior to that date in the absence of any such action. The priority and perfection of those security interests shall continue to be governed by Division 9 (commencing with Section 9101) as it existed prior to that date. However, on or before the last date on which any action is required under Division 9 (commencing with Section 9101) (as it existed prior to that date) to continue the perfection of the security
interest, in order to continue the perfection of the security interest the secured party, rather than complying with Division 9 (commencing with Section 9101), shall furnish to a party described in subparagraph (i), (iii), or (iv) of paragraph (h) of subdivision (1) of Section 8313, or if none of those is applicable, then to the issuer of the uncertificated security, either (x) a copy of either the financing statement previously filed to perfect the security interest or the security agreement that created the security interest, in either case bearing a copy or an original of the debtor’s signature, or (y) a written notification from the registered owner under paragraph (b) of subdivision (7) of Section 8403. Any such notice to an issuer shall be deemed a written notification under paragraph (b) of subdivision (7) of Section 8403, subject to the limitation that there can be no more than one registered pledge of an uncertificated security at any time (Section 8108). Except as otherwise provided in this
division, the provisions of Division 8 (commencing with Section 8101) as revised shall govern the rights and obligations of all persons with respect to a security interest in an uncertificated security that first attaches after January 1, 1985. All references in this section to Division 8 (commencing with Section 8101) or a section thereof are references to Division 8 (commencing with Section 8101) as revised by Chapter 927 of the Statutes of 1984.
