1.Retention Bonus. If you remain employed by the Company or an affiliate of the Company through the earliest of: (i) December 31, 2024; (ii) the consummation of a Sale Event (as defined below); or (iii) your termination by the Company without Cause (as defined below) (the earliest of (i), (ii) and (iii) is the “Retention Date”), the Company shall pay you a “Retention Bonus” equal to $115,500.05 (100% of your annual bonus target as in effect on the Retention Date) within 45 days after the Retention Date.

Event is reproduced for your convenience below: “Sale Event” shall mean (i) the sale of all or substantially all of the assets of the Company on a consolidated basis to an unrelated person or entity, (ii) a merger, reorganization or consolidation

pursuant to which the holders of the Company’s outstanding voting power and outstanding stock immediately prior to such transaction do not own a majority of the outstanding voting power and outstanding stock or other equity interests of the resulting or successor entity (or its ultimate parent, if applicable) immediately upon completion of such transaction, (iii) the sale of all of the Stock of the Company to an unrelated person, entity or group thereof acting in concert, or (iv) any other transaction in which the owners of the Company’s outstanding voting power immediately prior to such transaction do not own at least a majority of the outstanding voting power of the Company or any successor entity immediately upon completion of the transaction other than as a result of the acquisition of securities directly from the Company; provided, however, that in the event an Award is subject to Section 409A, no such event shall constitute a payment event unless such event is also a change of control event as defined by Section 409A.
