Preliminary Note

On August 2, 2023, the Reporting Persons in the aggregate acquired beneficial ownership of more than 5% of the Shares then outstanding. As reported by the Company on its Form 8-K filed with the SEC on August 11, 2023 (the “Company 8-K”), on such date the Company and Novartis AG (“Novartis”) closed their merger transaction (the “Novartis Merger”), as a result of which each outstanding Share was automatically converted into the right to receive the merger consideration described in the Company 8-K and the Company became a wholly-owned subsidiary of Novartis. Accordingly, as of August 11, 2023, the Reporting Persons ceased to have beneficial ownership of any Shares. See Item 5(e) below.
