If a court of competent jurisdiction should determine that Holder has received interest in excess of such lawful rate, such excess shall be applied to the reduction of the unpaid Principal Sum due hereunder and not to the payment of interest. 13. Grant and Perfection of Security Interest. In order to secure the due and punctual payment of the sums due hereunder, Borrower hereby grants, transfers, conveys and assigns to Holder, and grants to Holder a security interest in, Borrower's presently existing or hereafter acquired rights, title and interest in all of its tangible and intangible property, whether real or personal, including, without limitation, all Accounts, Contract Rights, Inventory, Equipment, General Intangibles, Chattel Paper, Deposit Accounts, Goods, Documents, Instruments and Proceeds (each as defined in the Uniform Commercial Code) of the foregoing (collectively, the "Collateral"); provided however, that Holder's security interest in the Collateral shall be subordinate to all security interests in the Collateral granted by Borrower and perfected prior to the date hereof. 14.
