Capital gains query - urgent

Hi everyone! 

In case - individual 'A' gives his own land to a company and acquires shares in it, how are capital gain provisions accrued in the hands of the A? 

Further, when the company later sells the land to another individual/entity, what are capital gain implications? In such case of sale, will the capital gain also arise in the hands of the A?

Kindly reply asap! Thanks in advance!
