The Borrower agrees that the Borrower's liability shall be unconditional, without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extensions of time, renewal, waiver or modification granted or consented to by the Payee. The Borrower agrees that additional guarantors or sureties may become parties hereto without notice to the Borrower or affecting its liability hereunder. The Borrower hereby waives and releases all errors, defects and imperfections in any proceeding instituted by the Payee under the terms of this Note.

No waiver of any rights and remedies hereunder, and no modification or amendment of this Note, shall be deemed made by the Payee unless in writing and duly signed by an officer of the Payee. Any such written waiver shall apply only to the particular instance specified therein and shall not impair the further exercise of such right or remedy or of any other right or remedy of the Payee, and no single or partial exercise of any right or remedy under this Note shall preclude any other or further exercise thereof or any other right or remedy. This Promissory Note inures to the benefit of the Payee and binds the Borrower, and their respective successors and assigns, and the words "Payee" and "Borrower" whenever occurring herein all be deemed and construed to include such respective successors and assigns. This Promissory Note is made and delivered in and shall be governed by the laws of the State of New Jersey without regard to principles of conflicts or choice of laws of any jurisdiction.
