Holders of pledged or hypothecated notes or other evidences of indebtedness pledged by state banking associations have the right to collect and enforce payment, and to renew or extend the time of payment thereof for a period not longer than fifteen months, if no endorser, guarantor, or joint maker would be released by such renewal or extension. Such holders also have the right:
The pledgee is entitled to be reimbursed from the pledged assets, or from the proceeds of the sale thereof, for the reasonable and necessary expenses incurred and expended in collecting, renewing, securing, and otherwise protecting the assets pledged or hypothecated to the pledgee.
