Transfer of security rights
1." A personal or property right securing payment of the assigned receivable is transferred to the assignee without a new act of transfer. If such a right, under the law governing it, is transferable only with a new act of transfer, the assignor is obliged to transfer such right and any proceeds to the assignee.
2." A right securing payment of the assigned receivable is transferred under paragraph 1 of this article notwithstanding any agreement between the assignor and the debtor or other person granting that right, limiting in any way the assignor's right to assign the receivable or the right securing payment of the assigned receivable.
