The general partner of RA Capital is RA Capital Management GP, LLC, of which Dr. Kolchinsky and Mr. Shah are the controlling persons.
RA Capital serves as investment adviser for the Fund and may be deemed a beneficial owner, for purposes of Section 13(d) of the Act, of

of all securities held in the Fund&rsquo;s portfolio, including the shares of the Issuer&rsquo;s Class A Common Stock reported herein.
Because the Fund has divested voting and investment power over the reported securities it holds and may not revoke that delegation on
less than 61 days&rsquo; notice, the Fund disclaims beneficial ownership of the securities it holds for purposes of Section 13(d) of the
Act. As managers of RA Capital, Dr. Kolchinsky and Mr. Shah may be deemed beneficial owners, for purposes of Section 13(d) of the Act,
of any securities of the Issuer beneficially owned by RA Capital. RA Capital, Dr. Kolchinsky, and Mr. Shah disclaim beneficial ownership
of the securities reported in this Schedule 13G/A other than for the purpose of determining their obligations under Section 13(d) of the
