    (b) Lien creditor. Except as otherwise provided in subsection (c), a security interest is subordinate to the rights of a person that becomes a lien creditor to the extent that the security interest secures an advance made more than 45 days after the person becomes a lien creditor unless the advance is made:
        (1) without knowledge of the lien; or
        (2) pursuant to a commitment entered into without

the buyer's purchase; or
