On March 22, 2022, the governing documents of SCV, SCV II, SCV III, SCV IV and Sibling Insiders LLC were amended such that the Reporting Person is no longer a co-manager or voting member of any of such entities. As a result, the Reporting Person is not a controlling member of, and does not have or share investment control over any portfolio securities beneficially owned by, SCV, SCV II, SCV III, SCV IV or Sibling Insiders LLC. ( 2 )The shares are held directly by Sibling Capital Fund II-A L.P. ("Sibling A"). SCV is the sole general partner of Sibling A. The shares continue to be held directly by Sibling A, but the Reporting Person is not an indirect beneficial owner of such shares as a result of the transactions described in footnote (1). ( 3 )The shares are held directly by Sibling Capital Fund II-B L.P. ("Sibling B"). SCV II is the sole general partner of Sibling B. The shares continue to be held directly by Sibling B, but the Reporting Person is not an indirect beneficial owner of such shares as a result of the transactions described in footnote (1). ( 4 )The shares are held directly by Sibling Capital Fund II-C L.P. ("Sibling C"). SCV III is the sole general partner of Sibling C. The shares continue to be held directly by Sibling C, but the Reporting Person is not an indirect beneficial owner of such shares as a result of the transactions described in footnote (1). ( 5 )The shares are held directly by Sibling Capital Fund II-D L.P. ("Sibling D"). SCV IV is the sole general partner of Sibling D. The shares continue to be held directly by Sibling D, but the Reporting Person is not an indirect beneficial owner of such shares as a result of the transactions described in footnote (1). ( 6 )The shares are held directly by Sibling Insiders Fund II L.P. ("Sibling Insiders Fund"). Sibling Insiders LLC is the sole general partner of Sibling Insiders Fund. The shares continue to be held directly by Sibling Insiders Fund, but the Reporting Person is not an indirect beneficial owner of such shares as a result of the transactions described in footnote (1). ( 7 )No actual transfer of the shares reported has occurred. This report is being filed to report that the Reporting Person no longer has a reportable beneficial interest in the shares directly held by Sibling A, Sibling B, Sibling C, Sibling D or Sibling Insiders Fund as a result of the transactions described in footnote (1). ( 8 )The spouse of the Reporting Person is the sole trustee of the Coufal Irrevocable Trust. The Reporting Person disclaims beneficial ownership of the shares held by the Coufal Irrevocable Trust except to the extent of her pecuniary interest therein, if any, and this report shall not be deemed an admission that the Reporting Person is the beneficial owner of the shares for the purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.
