The parties hereto acknowledge that this Agreement contains certain volume, pricing and term provisions that are confidential, proprietary or of a sensitive commercial nature and that would put the parties at a competitive disadvantage if disclosed to the public (“Confidential Information”). The parties further agree that all provisions of this Agreement shall be kept confidential and, without the prior consent of the other party, shall not be disclosed to any party not a party to this Agreement or the legal advisor of a party to this Agreement, except as required by law or governmental or judicial order and except that disclosure of the existence of this Agreement shall not be precluded by this Section.

This Agreement may not be modified or amended except by an instrument in writing executed by all of the parties hereto. No waiver of any breach of any of the terms of this Agreement shall be effective unless such waiver is in writing and signed by the party against whom such waiver is claimed. No waiver of any breach shall be deemed to be a waiver of any other or subsequent breach.

Except for the provisions of Sections I, II, and III, each of which are deemed essential to this Agreement, any provision of this Agreement prohibited by any applicable law of any jurisdiction shall as to such jurisdiction be ineffective, without modifying the remaining provisions of this Agreement. Where,

however, the conflicting provisions of any such law may be waived, they are hereby waived by the parties hereto to the full extent permitted by law. Additionally, if any provision of this Agreement is determined by a court or arbitrator to be prohibited by any applicable law of any jurisdiction, the parties hereby agree to negotiate in good faith to modify such provision to the minimum extent necessary to cause such provision to be lawful in such jurisdiction.

This Agreement shall inure to the benefit of and be binding upon the permitted successors and assigns of the respective parties hereto in all respects as if they were mentioned throughout by words of proper designation.
