Also on April 1, 2022, Dr. Dilly met with a representative of a biopharmaceutical company, that we refer to as “Party G,” in connection with
ongoing discussions between Sierra Oncology and Party G regarding opportunities for licensing, partnership and other strategic transactions. As part of
the discussion, Dr. Dilly and the representative discussed on a preliminary basis the possibility of a business combination between Sierra Oncology and
Party G, but deferred further discussion to a future date.
