Article 4 (Disposition of Security)

(1) In the event that the Borrower has failed to perform its obligations to the Bank, the Bank may collect or dispose of the security by following procedures stipulated by law or in a manner, at a time, and for a price, etc. generally deemed appropriate, and also, regardless of the legal priority, may appropriate to the repayment of the Borrower’s obligations the remainder of the proceeds after deducting expenses. After appropriation of the proceeds to the repayment of the Borrower’s obligations, should the Borrower’s obligations remain, the Borrower shall immediately repay such to the Bank, and should there occur a surplus in proceeds, the Bank shall return such to the entitled party.
