award agreement financial

"subject to continued compliance with the terms of the award agreement."

An award agreement is a legal contract that spells out the terms of a pay or equity grant—such as stock options, restricted shares, or cash bonuses—given to an employee, director or consultant. It describes what is being granted, any conditions for keeping it (for example, earning it over time or meeting performance targets), and what happens if the person leaves or breaks rules. Investors care because these agreements affect company costs, potential share dilution and how executives are motivated and rewarded.
