Mr. Mulvihill holds a Bachelor of Science in Mechanical Engineering degree from Queen’s University in Canada.

In connection with his employment by the Company as CFO, Mr. Mulvihill entered into an Offer Letter with the Company, effective October 11, 2023, pursuant to which Mr. Mulvihill will receive a base salary in the amount of $250,000, and a one-time sign-on bonus of $125,000 worth of the Company’s Class A Common Stock.
