Only two sites (IndiaBiz.co.in) & (NoLimit.in) was on URL Forwarding to our main company site. Didn't exactly know if this was the reason why these two domains got page rank. I thought & still believe the domain keywords are very strong. Anyways, am removing these two domains.
HyderabadHost.com - This domain has a custom website on it
WebsiteRenewal.com - This domain page rank is 3 and its not using any URL Forwarding
