Unless the terms of an optionholder’s stock option agreement, or other written agreement between Semnur and the recipient, provide otherwise, if an optionholder’s service relationship with Semnur or any of its affiliates ceases for any
reason other than disability, death or cause, the optionholder may generally exercise any vested options for a period of three months following the cessation of service. If an optionholder’s service relationship with Semnur or any of its
affiliates ceases due to death, or an optionholder dies within a
