Pursuant to the Separation Agreement and Release entered into by the Issuer and the reporting person on July 20, 2026 (the "Separation Agreement"), the Issuer agreed to make a cash payment of $5.23 per restricted stock unit ("RSU") for the 80,393 RSUs that vested as of July 1, 2026 in full satisfaction of such RSUs.
