The South Carolina Stock Option Plan is a program implemented by Sunrise Assisted Living, Inc. that aims to provide its employees, consultants, and advisers with the opportunity to purchase company stock options at a predetermined price. This plan includes the provision of both Incentive Stock Options (SOS) and Nonqualified Stock Options (SOS) to eligible participants. SOS are stock options granted exclusively to employees and are subject to various tax advantages provided by the Internal Revenue Code. Employees who are granted SOS have the right to purchase company stock at a discounted price within a specified time frame. These options are designed to incentivize and retain talented individuals within the organization, as the potential for future stock appreciation increases if the company performs well. On the other hand, SOS are stock options granted to employees, consultants, and advisers who don't meet the requirements of ISO eligibility. SOS are not subject to the same tax advantages as SOS, and the pricing of these options is typically determined based on the fair market value of the company's stock at the time of grant. SOS offer flexibility compared to SOS, as they may be granted to a broader range of individuals involved with the company. Sunrise Assisted Living, Inc. offers both SOS and SOS under the South Carolina Stock Option Plan to ensure that a diverse group of employees, consultants, and advisers can participate in the program. By providing different types of stock options, the company aims to reward and incentivize its workforce, while also accommodating the varying needs and requirements of its participants.
