Format of director's declaration for conversion of private limited company into one person company

Dear Professional Colleagues,

We are in the process of converting a private limited company into OPC. For this purpose we need to attach a declaration by the directors by way of affidavit. Does anybody have a format for this? And also should each director give a declaration or all of them together?

Thanks in advance.
