During this time, you continue to be bound by the express and implied obligations of your employment agreement and will not have any contact or communication with any client or customer of the Company save with the prior written consent of the Company. 2. Acknowledgment of Payment of Wages : The Company will pay you your contractual salary, including the monthly lump sum to cover your housing and health care coverage premiums as set forth in Section 6.5 of the employment contract, dated January 10, 2022, between you and the Company, until the Separation Date as usual.

Covenant Not to Sue : a. To the fullest extent permitted by law, at no time subsequent to the execution of this Agreement will you pursue, or cause or knowingly permit the prosecution, in any Swiss or foreign court, or before any Swiss or foreign administrative agency, or any other tribunal, any charge, claim or action of any kind, nature and character whatsoever, known or unknown, which you may now have, have ever had, or may in the future have against Releasees, which is based in whole or in part on any matter covered by this Agreement. b.
