What is the meaning for "date for the purpose of Sub-division of shares"?
It is in context of stock split, where the face value of share is split into lower denomination. i.e. 10Rs face-value share is split as 5 Rs or 2 Rs etc. The date on which such split is decided by the company, the equity holder will get the benefit of such split if they are holding the shares as on "the date for purpose of sub-division of shares"

Even one can sell his shares on exdate & to get benefit for any corporate action one should buy that share before Ex date of the company.

on or before the ex-date is my understanding. But I am not sure of it. Let some legal expert in this forum clarify from Companies Act.
