Further, for all purposes under this Agreement, (i) the Phase 1 Convertible Notes shall be considered, along with any Unexchanged 2021 Convertible Notes, as 2021 Convertible Notes and (ii) the Phase 2 Convertible Notes shall be considered, along with any Unexchanged 2022 Convertible Notes, as 2022 Convertible Notes.
