to earn a living. Executive acknowledges that it may be impossible to asses the monetary damages occurred by Executives violation of sections 6, 7 or 8 of this Agreement, that violations of those sections will be material breaches of this

effect for a period of one year from the date of the final Court Order enforcing this Agreement.
