(o) Without notice or demand to the Debtor, set off and apply against any and all of the Secured Indebtedness any and all deposits (general or special, time or demand, provisional or final) at any time held or owing by such Secured Party or any of such Secured Party’s agents or affiliates to or for the credit of the account of the Debtor.

(p) Exercise any other remedies available to such Secured Party at law or in equity.

7. MISCELLANEOUS.

(a) Any waiver, express or implied, of any provision hereunder and any delay or failure by any Secured Party to enforce any provision shall not preclude the Secured Parties from enforcing any such provision thereafter.

(h) In the event the Secured Parties seek to take possession of any or all of the Collateral by judicial process, the Debtor hereby irrevocably waives any bonds and any surety or security relating thereto that may be required by applicable law as an incident to such possession, and waives any demand for possession prior to the commencement of any such suit or action.

(i) This Agreement shall constitute a continuing agreement, applying to all future as well as existing transactions, whether or not of the character contemplated at the date of this Agreement, and if all transactions between the Secured Parties and the Debtor shall be closed at any time, shall be equally applicable to any new transactions thereafter.

(j) No amendment or waiver of any provision of this Agreement and no consent by the Secured Parties to any departure therefrom by the Debtor shall be effective unless such amendment, waiver or consent shall be in writing and signed by each Secured Party, and any such amendment, waiver or consent shall then be effective only for the period and on the conditions and for the specific instance specified in such writing.
