As previously announced on December 16, 2022 in a Current Report on Form 6-K filed by Bionomics Ltd. (now known as Neuphoria Therapeutics Inc., or the “Company”), the Company had appointed Spyridon “Spyros” Papapetropoulos, M.D. as President and Chief Executive Officer (“CEO”) pursuant to the terms of that certain Employment Agreement effective January 5, 2023 (“Employment Agreement”), and as a director to the Company’s board.

Effective December 31, 2025, Mr. Papapetropoulos will cease to serve as the full-time President and CEO of the Company and his Employment Agreement shall have terminated on such date; however, he will remain as a member of the Company’s Board of Directors. Pursuant to the terms of the Employment Agreement, Mr. Papapetropoulos is entitled to severance payment in an aggregate amount equal to his annual base salary, target bonus amount, and medical insurance premiums, which shall be paid in an amount equal to 50% of such gross severance in calendar year 2025, and the balance of such severance to be paid in partial installments in 2026 until fully paid in full, subject to and in accordance with the Company’s regular payroll, withholding practices and applicable law. Except as required by applicable law, Mr. Papapetropoulos’ participation in, coverage by, and entitlement to all compensation, fringe benefits, and employee benefits programs of the Company terminate immediately; however, as a continuing service provider and director, Mr. Papapetropoulos will continue to have rights in and to outstanding stock options, which shall continue to vest and be exercisable under the terms of the equity incentive plan.

Simultaneously and in connection with the termination of the Employment Agreement, Mr. Papapetropoulos entered into a Consulting Agreement with the Company (the “Consulting Agreement”) effective January 1, 2026, under which Mr. Papapetropoulos will serve as the interim CEO to the Company for up to twelve months to support the execution of the Company’s contemplated strategic transaction and ensure a seamless transition. Under the terms of the Consulting Agreement, Mr. Papapetropoulos will receive consulting fees equal to $800 per hour for services up to approximately 40 hours per month for his continued services, which aggregate hours shall not exceed more than twenty percent of the total hours performed while acting as the full-time CEO of the Company. The Consulting Agreement shall automatically terminate upon the earlier of twelve months from entry or the consummation of a strategic merger, change of control or similar transaction by the Company.
