Mike,

try using prefix-list filtering on ASA instead of dividing OSPF into two
different processes. If you want to block prefix 2.2.2.2/32 from being
advertised into another area, first configure prefix-list denying prefix
2.2.2.2/32 and allowing other prefixes:

prefix-list OSPF seq 5 deny 2.2.2.2/32
prefix-list OSPF seq 10 permit 0.0.0.0/0 le 32

Then apply it to OSPF configuration on ASA:

router ospf 1
 router-id 11.45.45.11
 network 10.0.10.0 255.255.255.0 area 1
 network 192.168.10.0 255.255.255.0 area 0
 area 1 filter-list prefix OSPF out
