I know the question originator did not explicitly ask for this but anyway...
AFAIK, one of differences between Cisco and Juniper implementations of RIP is that on Juniper routers RIP does not advertise even connected subnets it is running over : 
http://www.juniper.net/techpubs/software/junos/junos73/swconfig73-routing/html/rip-config2.html#1014087 , 
"The local router imports all routes by default from this neighbor and does not advertise routes"

So to make it 100% compatible with Cisco RIP implementation the above JUNOS RIP export policy (policy-statement default) should contain an additional term (named "connected" in the example below) between terms "conditional" and "suppress", something like:

term connected {
from protocol direct;
route-filter <whatever subnets RIP is running over>;
}
then accept:

HTH
