Legal implication of a non-compete agreement

I have signed an internal employment agreement, which states that I cannot work with the competitor if I resigned.

"The employee covenant with the company that he will not for a period of twelve months after the date of termination of his employment for whatever reason, be concerned in any the business which is carried on in the UAE and which is competitive with any business which is carried on by the company at the time of termination. The employee shall not after the termination of this agreement directly or indirectly on his own account or on behalf of or in conjunction with any person for a period of 12 months thereafter induce or attempt to induce any employee to whom this subclause applies to leave the employment of the company."

What is the legal status of this agreement?

This is an internal agreement in English only and has not been attached to the labour contract.
