The Agreement, together with the Appendices and Schedules, constitutes the entire agreement between the parties with respect to the subject-matter hereof and supersedes any and all written or oral prior agreements and understandings between the parties.  No terms or conditions of either party’s invoice, purchase order or other administrative document (unless signed by authorized representatives of both parties and expressly referencing that it amends this Agreement) will be effective as a modification of the terms and conditions of this Agreement or a Schedule, regardless of the other party’s failure to object to such form.
