(2) As long as and to the extent that an issuer or nominated person has not been reimbursed or has not otherwise recovered the value given with respect to a security interest in a document under subsection (1) of this section, the security interest continues and is subject to ORS chapter 79, but:
(a) A security agreement is not necessary to make the security interest enforceable under ORS 79.0203 (2)(c);
(b) If the document is presented in a medium other than a written or other tangible medium, the security interest is perfected; and
(c) If the document is presented in a written or other tangible medium and is not a certificated security, chattel paper, a document of title, an instrument, or a letter of credit, the security interest is perfected and has priority over a conflicting security interest in the document as long as the debtor does not have possession of the document.
