You ifconfig'ed without specifying a netmask, correct ?
Then a netmask of 0xffffff00 is assumed in your case (depends on the
nature of the IP-address IIRC; have a look at "man route")
Applying a netmask of 0xffffff00 to the IP-addresses 10.10.10.3
and 10.10.10.5 gives the same network. Now ifconfig complains that
you want to assign the same network to different devices.
Try to give an explicit "netmask" argument to ifconfig.
