Notes on MSK Relationship and Conflict Controls

Overall, Scheinberg’s scientific expertise and committee leadership support board effectiveness and clinical strategy oversight, with governance structures (independence, attendance, policies) mitigating potential MSK-related conflicts; director pay appears appropriately modest and primarily time-based equity, aligning with standard small-cap biotech practices .
