"Restricted stock units are forfeited if Reporting Person's service as an officer of the Company is terminated prior to the fifth (5th) anniversary"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
