and authority to make the agreements contained in this Fifth Renewal without
joinder and consent of any other party; and (c) the execution, delivery and

modified, has been fully paid, and agrees that such extension, renewal and
modification shall in no manner affect or impair the Note, the liens or
security interests securing same, and that said liens, security interests, and

Trust in form satisfactory to Payee, and the reasonable fees and expenses of
