$420,000 Part-Time CFO Terms

Lieber’s transition is set for September 15, 2026, under an agreement with Rallybio and Rallybio, LLC. The arrangement allows him to participate in Rallybio’s benefit plans while removing eligibility for an annual Bonus for 2026 and every later year in which he remains employed. Lieber may also pursue other Business activities, including work as an employee or officer elsewhere, provided those activities do not unreasonably interfere with his responsibilities or create a business or Fiduciary conflict. His part-time status is not treated as a separation from service for tax purposes.

Employment Tied to Avenzo Closing

If Rallybio ends his employment without Cause before the closing, the agreement provides for severance payments and benefits under his existing employment arrangements. If the Merger closes after that termination, the applicable closing-related payments and benefits replace those earlier amounts without duplication. If the Merger Agreement ends under its terms, Lieber will not receive severance payments or other benefits connected with that transaction.
