CFO Employment Agreement

On May 15, 2025, we entered into an employment agreement with our Chief Financial Officer and principal accounting officer, Joshua Malm (the “Employment Agreement”). The Employment Agreement entitles Mr. Malm to cash compensation of $300,000 per year for his service as our Chief Financial Officer. Pursuant to the Employment Agreement, Mr. Malm is eligible to earn an annual bonus of up to 80% of his then-in-effect base salary (on target performance would result in a bonus payment equal to 40% of Mr. Malm’s then-in-effect base salary), subject to the achievement of performance objectives as determined by the Board.

Regardless of the manner in which Mr. Malm’s employment terminates, he is entitled to receive certain accrued amounts previously earned during his employment, including unpaid salary, reimbursement of expenses owed, and accrued but unpaid paid time off and any continuation of benefits required by applicable law.

In addition, Mr. Malm is entitled to certain severance benefits under his employment agreement, subject to his execution of a release of claims and compliance with post-termination obligations. Pursuant to Mr. Malm’s employment agreement, upon a termination of his employment by the Company for reasons other than for “cause” or by Mr. Malm for “good reason” (each term as defined in the employment agreement), Mr. Malm is entitled to (i) an amount in cash equal to six months of annual base salary, payable in a lump sum, (ii) a pro-rated bonus based on target performance for the portion of the year he was employed, (iii) payment of the COBRA premiums for Mr. Malm and his eligible dependents for a maximum period of up to 6 months from the date of his termination of employment, and (iv) accelerated vesting of all unvested Company equity awards, provided that any Company equity awards that vest based on the attainment of performance goals will remain outstanding and will be eligible to vest in accordance with the terms of the applicable award agreements, provided, further, that in the event such termination occurs during the period commencing on the date that is three (3) months prior to a change in control and ending on the date that is eighteen (18) months following a change in control, any performance stock units (“PSUs”) outstanding where the termination date is within twelve (12) months of the end of their respective performance period(s), and there is a reasonable probability that the respective performance goal(s) for such PSUs would have been achieved at target (or above) absent the change in control, then such PSUs that would have vested within such twelve (12) month period following the change in control shall also vest.
