I am not able to Ping host host in OSPF Area 1 from OSPF Area 0

I have set up a simple OSPF network in Packet Tracer. I see all neighbors up - I am able to ping interface withing a OSPF area. I am unable to ping a host crossing over OSPF area.

 

I am refreshing myself on routing after a 6 year absence - Please be nice with your responses - What am I missing here?
