5.2 No Waiver. Neither the execution by the Administrative Agent or the Lenders party hereto of this Fifth Amendment, nor any other act or omission by the Administrative Agent or the Lenders or their officers in connection herewith, shall be deemed a waiver by the Administrative Agent or the Lenders of any Defaults or Events of Default which may exist, which may have occurred prior to the date of the effectiveness of this Fifth Amendment or which
