Officer Severance Plan (the “Officer Severance Plan”) initially adopted by the Company effective June 28, 2023. The Amended and Restated Officer Severance Plan extends the term of the Officer Severance Plan to December 31, 2026, and thereafter, automatically renews at the end of each calendar year for successive one-year terms unless amended or otherwise terminated by the Administrator (as defined in the Amended and Restated Officer Severance Plan) after December 31, 2026, with at least twelve months prior written notice. The terms of the Amended and Restated Officer Severance Plan otherwise does not materially differ from the Officer Severance Plan.
