Private Limited companies Director to contribute ESI & PF?

Hi,
I need clarification about Pvt. Ltd companies director to act as full time employee and his share holding profit portion shared to companies development and employee's benefits. Is he eligible to contribute the ESI & PF?

If the salary conditions permits the directors are also covered under ESI and EPF. As such if the salary does not exceed Rs 21000, they are covered under ESI and if they were previously employed as a member of PF and or if their salary in the present organisation is not more than Rs 15000, they should be covered by EPF also.
