Notwithstanding, the filing of this Statement shall not be construed as an admission that: (i) the 2019 Partnership, 2019 GP and 2019 LLC (collectively, the “2019 Affiliates”), on the one hand, or (ii) the 2021 Partnership, 2021 GP and 2021 LLC (collectively, the “2021 Affiliates”), on the other hand, is or has been, for purposes of Sections 13(d) or 13(g) of the Exchange Act, the direct or indirect beneficial owner of any of the Issuer’s securities reported herein as beneficially owned by the other.
