As to each and every Claim released hereunder, each Loan Party hereby represents that it has received the advice of legal counsel with regard to the releases contained herein, and having been so advised, specifically waives the benefit of the provisions of Section 1542 of the Civil Code of California which provides as follows:

Each Loan Party further agrees that it shall not dispute the validity or enforceability of the Credit Agreement or any of the other Loan Documents or any of its obligations thereunder, or the validity, priority, enforceability or the extent of Lender’s Lien on any item of Collateral under the Credit Agreement or the other Loan Documents.

            19.        Reservation of Rights . Nothing contained in this Agreement is intended to or shall be construed as (a) a waiver, release, modification or forbearance of any of the rights, remedies, privileges and powers of Lender against any Loan Party or any other Person, or the Collateral, or a waiver of any Defaults or Events of Default, (b) a mutual disregard of the terms and provisions of the Credit Agreement or any Loan Document, (c) a course of dealing in variance with the terms and provisions of the Credit Agreement or any other Loan Document, (d) an agreement of any Lender to make extensions of credit to any Loan Party under the Credit Agreement or any other Loan Document, or (e) a consent to any departure by any Loan Party from the express provisions of the Credit Agreement or any other Loan Document. Lender shall not by virtue of any action or omission, including the acceptance of any payment under the Credit Agreement, be deemed to have altered or prejudiced any remedies, powers, rights, or privileges under the Credit Agreement or any other Loan Document in connection with any Default or Event of Default. Lender hereby expressly reserves all of its remedies, powers, rights, and privileges under the Credit Agreement or the other Loan Documents, at law (including under the UCC), in equity, or otherwise.
