Note re Swiss law applicability. Mr. Muller is resident in Zurich, Switzerland. To the extent any provision of this Section is interpreted as a post-termination non-compete enforceable against him in Switzerland, such enforcement is subject to Swiss Code of Obligations Articles 340–340c, including the requirements that any post-termination non-compete (i) be in writing, (ii) be limited to a reasonable duration not exceeding three years, (iii) be reasonable in geographic and functional scope, and (iv) protect a substantial business interest such as access to confidential information or substantial customer-relationship influence. Swiss courts may reduce or set aside non-competes deemed excessive. The Company has not adopted any post-termination non-compete against Mr. Muller pending Swiss employment counsel review (see Doc 22 §F.24).

Independence footnote. Mr. Muller does not qualify as “independent” under Nasdaq Listing Rule 5605(a)(2) or NYSE Listed Company Manual §303A.02. He is a founder, officer (Treasurer and Secretary), 25% shareholder, and party to a Founder and Director Agreement with the Company. The Company currently has no independent directors within the meaning of those rules. References in this document to Mr. Muller as a “qualified director” use the term of art defined in Wyoming Business Corporation Act §17-16-831(a)(3) — a director who does not have a conflicting interest in the specific transaction under review. This is a narrower and lower statutory standard than the “independent director” standard under Nasdaq Listing Rule 5605(a)(2) or NYSE Listed Company Manual §303A.02, which requires the absence of any material relationship with the Company. A director may be a “qualified director” for purposes of a specific related-party transaction while still not meeting the listing standards’ “independent director” definition.
