§12A-9-311.
   
   The debtor's rights in collateral may be voluntarily or involuntarily
   transferred (by way of sale, creation of a security interest,
   attachment, levy, garnishment or other judicial process)
   notwithstanding a provision in the security agreement prohibiting any
   transfer or making the transfer constitute a default, but the interest
   so transferred is subject to the creditor's security interest if it is
   properly perfected, and nothing stated herein shall be construed to be
   inconsistent with 21 O.S., Sec. 1834.
