In consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, the parties agree as follows:

1.    Section 2(a) of the Employment Agreement is hereby amended and restated in its entirety as follows:

“Base Salary. Executive shall be paid a base salary (“Base Salary”) at the annual rate of Five Hundred Thousand Dollars ($500,000), payable in semi-monthly installments consistent with Company’s payroll practices, starting May 2026. The annual Base Salary shall be reviewed on or before December 31 of each year, unless Executive’s services with the Company shall have been terminated earlier pursuant to this Agreement. By December 31 of each year, the Board of Directors of the Company shall determine if such Base Salary should be increased for the following year in recognition of services to the Company. Executive shall receive a car allowance of $2,000 per month, payable within 30 days following each month, for a guaranteed term of 36 months starting May 2026, regardless of any termination of this Agreement, except in the event of a material breach of this Agreement by Executive. In recognition of Executive’s accomplishments on behalf of the Company, the Company shall pay Executive a total of $125,000 in calendar year 2026. The Company will use its best efforts to make the payment for calendar year 2026 in equal monthly installments (and in any event in 2026). The payment shall not be contingent upon Executive’s continued service with the Company through the payment date and shall continue upon any termination of this Agreement.

2.    A new Section 2(d) is hereby added to the Employment Agreement as follows:

“Bonus Grant. Executive, or, in Executive’s discretion, Executive’s designated entity or assignee, will receive a grant of 1,500,000 shares of the Company’s common stock (the “Bonus Grant”) upon a Change in Control (as defined in the Company’s 2017 Equity Incentive Plan or any successor plan, including any successor plan adopted in connection with such Change in Control (the “Equity Plan”))¹, subject to Executive’s continuous service through the relevant date of grant. The Bonus Grant will vest in full upon grant. With respect to the Bonus Grant, any tax withholding, if applicable, shall be covered by a Company-arranged broker-assisted sell-to-cover transaction with respect to a number of the covered shares of common stock equal in fair market value to such tax withholding, subject to any limitations imposed by applicable law. Subject to any limitations imposed by applicable law, Executive will be permitted to sell a number of the covered shares on the open market to cover any other taxes triggered in connection with the Bonus Grant or the shares covered thereby. The Bonus Grant will be governed by, and subject to, the terms and conditions of an award agreement (including the terms of this Section 2(d)) to be entered into between the Company and the Executive at the time of grant. The Company and Executive will reasonably cooperate to structure the timing and form of any equity compensation (including the Bonus Grant) in a tax-efficient manner consistent with applicable tax laws, securities laws, and the Equity Plan, including in order to assist Executive to address any tax obligations triggered in connection with the Bonus Grant. Notwithstanding anything herein to the contrary, the grant of the Bonus Grant shall be subject to, and conditioned upon, the approval by the Company’s shareholders of a sufficient number of shares available for issuance under the Equity Plan, in accordance with applicable laws and the rules of the stock exchange on which the Company’s shares are listed, prior to or in connection with the Change in Control giving rise to such grant. Notwithstanding the foregoing, the Company shall have the right, in its sole discretion, to pay the Bonus Grant in cash in lieu of shares of the Company’s common stock, in an amount equal to the product of (i) the number of shares subject to the Bonus Grant and (ii) the closing price of a share of the Company’s common stock on the date of grant, and Executive hereby consents to such cash settlement.”

3.    Section 3(b) of the of the Employment Agreement is hereby amended and restated as follows:

“Benefit Plans. Executive shall be entitled to participate in the Company’s benefit plans offered by the Company to its employees during the term of this Agreement. Nothing in this Agreement shall preclude the Company from terminating or amending any employee benefit plan or program from time to time. Notwithstanding the foregoing, beginning in June 2026, Executive will be provided comprehensive health benefits for Executive and Executive’s dependents, including major medical insurance, dental and life insurance, and short-term and long-term disability. If, for a calendar month, the Company does not provide such health benefits to Executive, the Company will pay Executive a cash payment that, on an after-tax basis, is sufficient for Executive to purchase such benefits for Executive and Executive’s dependents, which payment may be used by Executive for any reason.”

4.    Section 5(b) of the Employment Agreement is hereby amended and restated as follows:

“Without Cause. The Company may terminate Executive’s services at any time without Cause by giving sixty (60) days’ notice. For the avoidance of doubt, a requirement by the Company that Executive resign his service hereunder in connection with the Closing shall constitute a termination of Executive’s services hereunder by the Company without Cause.”

“Resignation. Executive may terminate this Agreement on a date set forth in a written notice of Executive’s resignation (other than for Good Reason) delivered to the Company by Executive (which date shall be no less than sixty (60) days after the Company’s receipt of such written notice, unless waived by the Company in writing).”

8.    A new Section 12(n) is added as follows:

“It is intended that any amounts payable under this Agreement shall either be exempt from or comply with Section 409A of the Internal Revenue Code (“Section 409A”) and this Agreement shall be interpreted accordingly.
