The founders of a startup agreed with an early employee to reward his work in case the company is successful. The reward will be done via a share transfer at the moment of exit. This is a private agreement between the founders and the early employees, it does not involve the Company. The founders are doing this out gratitude, the employee does not have any right to be rewarded.
We have drafted a very short contract that reflects what was agreed between the founders and the employee. We want to keep this simple but we would like a lawyer to go through it and make sure the contract is sufficiently clear to prevent possible future disagreements and disputed.
The applicable law should be the law of England and Wales
