Try this in R3:
!
interface Serial2/0
no ip address
encapsulation frame-relay
frame-relay interface-dlci 304 ppp Virtual-Template1
frame-relay interface-dlci 305 ppp Virtual-Template2
frame-relay lmi-type cisco
!
interface Virtual-Template1
ip address 158.1.0.3 255.255.255.0
ppp authentication pap chap
!
interface Virtual-Template2
ip address 158.1.0.3 255.255.255.0
ppp authentication pap chap
!
And let me know if it solves the problem.

Ivan,
Thanks for your reply.
I tried changing the subnet to 158.1.44.0/24 . But that does not solve the
issue.
R5 & R3 are able to ping R4's loopback but R4 does not receive any eigrp
updates from the hub R3 or the spoke R5. Kind of peculiar situation i am in.
Dont see a reason for this.
Regards
Shameen
