| F1 | This represents an award of restricted stock units to the Issuer's non-employee director. Each unit represents a contingent right to receive one share of the Issuer's common stock upon vesting. One hundred percent (100%) of the restricted stock units was scheduled to vest on September 15, 2025, but settlement has been deferred under our non-employee director RSU deferral program. |
