6. Align Product Trademarks.

(1) Use. Subject to subsection (F)(2) below, during the term of this Agreement, Discus shall have the right to indicate to the public that Discus is an authorized representative of the Align Product Trademarks and to advertise within the Territory such Products under the Align Product Trademarks.

(2) Approval of Representations. All representations of the Align Product Trademarks that Discus intends to use shall first be submitted to Align for approval, which shall not be unreasonably withheld or delayed, of design, color, and other details or shall be exact copies of those used by Align. If any Align Product Trademarks are to be used in conjunction with another trademark on or in relation to the Products, then the Align Product Trademark shall be presented equally legibly, equally prominently, and of equal or greater size than the other but nevertheless separated from the other so that each appears to be a mark in its own right, distinct from the other mark.

Without in any way limiting subsection (F)(3) above, the parties hereby agree that at no time during or for a period of eighteen (18) months after the term of this Agreement shall either party challenge or assist others to challenge any Trademark of the other party or the registration thereof, or use or register, or attempt to use or register, any Trademarks, marks or trade names confusingly similar to those of the other party.

Nonperformance of either party shall be excused to the extent that performance is rendered impossible by strike, fire, flood, governmental acts or orders or restrictions, failure of suppliers, war, terrorism or any other reason where failure to perform is beyond the reasonable control of and is not caused by the negligence of the non-performing party.
11. No Implied Waivers. The failure of either party at any time to require the performance by the other party of any provision hereof shall not affect in any way the full right to require such performance at any time thereafter, and the waiver by either party of a breach of any provision hereof shall not be taken or held to be a waiver of the provision itself.
12. Controlling Law. This Agreement shall be governed by, and construed and interpreted in accordance with, the laws of the State of California, United States of America, without reference to conflict of laws principles or statutory rules of arbitration. Subject to Section X(M) below, the federal and state courts within the State of California, United States of America shall have exclusive jurisdiction to adjudicate any dispute arising out of this Agreement.

15. No Third Party Rights. Except the right to indemnify the officers, directors, and shareholders of each company as provided for in Sections X(A)(1) and X(A)(2), nothing in this Agreement, whether express or implied, is intended to confer any rights or remedies under or by reason of this Agreement on any persons other than the parties hereto.
16. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.
17. Binding Effect. A mutually agreed consideration for Align's entering into this Agreement is the reputation, business standing, and goodwill already honored and enjoyed by Discus under Discus's present ownership, and, accordingly, subject to Section X(I) Discus agrees that Discus's rights and obligations under this Agreement may not be transferred or assigned directly or indirectly without the prior written consent of Align. Subject to the foregoing sentence, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their successors and assigns.
