Tunneling to area 0 in OSPF

I tried doing a tunnel from a router (R3) with only OSPF area 50 configured to
another (R2) through a serial link running only RIP. I set up a tunnel
(extending the area 0 to R3). But for some reason, I get the following
reoccuring message:

R3.....
06:05:16: OSPF: Rcv hello from 160.10.37.2 area 0 from Tunnel0 10.1.1.1
06:05:16: OSPF: End of hello processing

This only occurs at R3. At first, I thought the hello/dead timer were an
issue, but that is not the case. the links come up and so does the tunnel.
However, OSPF routes from area 50 will not get passed into the other routers
on area O. Here are the configs....any ideas on this one?
