The Nevada Stock Option Plan of Sunrise Assisted Living, Inc. is a comprehensive program designed to offer employees, consultants, and advisers the opportunity to receive Incentive Stock Options (SOS) and Nonqualified Stock Options (Nests) as a form of compensation. This plan aims to incentivize and reward key individuals for their contributions to the company's growth and success. Incentive Stock Options: Incentive Stock Options (SOS) are one type of stock option available under the Nevada Stock Option Plan. These options are granted to employees with the intention of providing them with potential tax advantages. SOS allow employees to purchase company stock at a predetermined price, known as the exercise price, within a specified timeframe. These options encourage employees to stay with the company and contribute to its long-term success. Nonqualified Stock Options: Nonqualified Stock Options (Nests) are another type of stock option offered by the Nevada Stock Option Plan. Unlike SOS, Nests do not offer the same tax advantages. They are generally granted to a broader group of individuals, including consultants and advisers, and provide greater flexibility in terms of vesting periods and exercise prices. Nests allow recipients to purchase company stock at the current market price at the time of exercise. The Nevada Stock Option Plan of Sunrise Assisted Living, Inc. is carefully designed to align the interests of employees, consultants, and advisers with the company's strategic goals. Through the grant of SOS and Nests, eligible individuals are provided with an opportunity to share in the company's success while potentially benefiting from favorable tax treatment (in the case of SOS). This plan serves as a valuable tool for attracting, motivating, and retaining talent as well as fostering a sense of ownership and loyalty among key contributors.
