Employee earning a basic salary more than 15k p.m. can choose to be exempted from PF deductions?

Hi, Is there any format/Form where an employee earning a basic salary more than 15k p.m. can choose to be exempted from PF deductions. There is an amendment to the PF rules recently.

employer has no choice to make the employee exempt. he has to provide the form 11 to employee to fill and return.
if the employee has any old UAN from any past services i.e has been contributory to any provident fund account in past. he must have to be a member irrespective of 15000 ceiling.
if the employee is joining fresh. then he has to submit the form 11 and a request to employee for his exercise of option not participating in EPF.
in case of no communication is found in records, the EPF will count the member as contributory, and will issue demand to employer, it does not matter that his basic is above 15000 or not

unconditional exemption is granted to employees only above 58+ years of age

Epf is increased rs.21000/- or to still rs.15000/- only? If any notification is there for increasing rs.21000/- kindly provide the same.
Some one has putting service of 25 yers and above with a member of epf. He is drawing more than rs.25000/- consolidated. We have to deduct epf on 21000/- or 15000/. Please guide me.
