On March 16, 2023, pursuant to a Business Combination Agreement dated as of September 29, 2022 (the "Business Combination Agreement"), by and among SMIH, YishengBio Co., Ltd ("YS Biopharma"), Oceanview Bioscience Acquisition Co., Ltd., a direct wholly owned subsidiary of YS Biopharma ("Merger Sub I") and Hudson Biomedical Group Co., Ltd., a direct wholly owned subsidiary of YS Biopharma ("Merger Sub II"), (i) Merger Sub I merged with and into SMIH (the "First Merger"), with SMIH surviving the First Merger as the surviving entity (the "Surviving Entity") and remaining as a wholly-owned subsidiary of YS Biopharma and (ii) the Surviving Entity merged with and into Merger Sub II (the "Second Merger"), with Merger Sub II surviving the Second Merger as the surviving company (the "Surviving Company") and remaining as a wholly-owned subsidiary of YS Biopharma.
