(c) Diplomat agrees to sell to KI, Inc. such quantities of the products at as low a rate and on as good terms as Diplomat sells similar quantities of the products to the general trade. 13. Records. Diplomat agrees to keep accurate books of account and records covering all transactions relating to the license hereby granted. KI, Inc. and its duly-authorized representatives shall have the right, upon reasonable notice and at reasonable hours of the day, to visit the offices of Diplomat one time each calendar quarter for the purpose of examining said books of account and records, and all other documents and materials in the possession or under the control of Diplomat, with respect to the 8 subject matter and terms of this Agreement, and shall have free and full access thereto for said purposes and for the purpose of making extracts therefrom.

In the event that Diplomat does not commence selling such product in commercial quantities within 90 days after such notice, such notice shall be deemed to be a termination of this License with respect to such product. (b) If Diplomat files a petition in bankruptcy, or is adjudicated a bankrupt, or if a petition in bankruptcy is filed against Diplomat, or if it becomes insolvent, or it makes an assignment for the benefit of its creditors or an arrangement pursuant to any bankruptcy law, or if Diplomat discontinues its business, or if a receiver is appointed for it or its business, the license hereby granted shall automatically terminate forthwith without any notice whatsoever being necessary. In the event this license is so terminated, Diplomat, its receivers, representatives, trustees, agents, administrators, successors and/or assigns shall have no right to sell, exploit or in any way deal with or in any of the products covered by this Agreement, or any carton, container, packing or wrapping material, advertising, promotional or display material pertaining thereto, except with and under the special consent and instructions of KI, Inc. in writing, which they shall be obligated to follow. (c) If Diplomat shall violate any of its other material obligations under the terms of this Agreement, KI, Inc. shall have the right to terminate the license hereby granted upon twenty (20) days' notice in writing, and such notice of termination shall become effective unless Diplomat shall 9 completely remedy the violation within the twenty-day period and satisfy KI, Inc. that such violation has been remedied.
