(b) Except as otherwise provided in subsection (e) of this section, a buyer, other than a secured party, of tangible chattel paper, tangible documents, goods, instruments or a certificated security takes free of a security interest or agricultural lien if the buyer gives value and receives delivery of the collateral without knowledge of the security interest or agricultural lien and before it is perfected.

(c) Except as otherwise provided in subsection (e) of this section, a lessee of goods takes free of a security interest or agricultural lien if the lessee gives value and receives delivery of the collateral without knowledge of the security interest or agricultural lien and before it is perfected.

(d) A licensee of a general intangible or a buyer, other than a secured party, of collateral other than tangible chattel paper, tangible documents, goods, instruments or a certificated security takes free of a security interest if the licensee or buyer gives value without knowledge of the security interest and before it is perfected.
