(the "Fund"), RA Capital Nexus Fund, L.P. (the "Nexus Fund") and a separately managed account (the "Account"). The Reporting Person is obligated to turn over to the Adviser any net cash or stock received as compensation from the Issuer, which will offset advisory fees owed by the Fund, the Nexus Fund and the Account to the Adviser.
