If you want 10.0.0.0/8 to be unshaped by htb and the rest go to 1:10, 
don't set a default class and filter like -

tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dst 
10.0.0.0/8 flowid 1:99

tc filter add dev eth0 protocol ip parent 1:0 prio 2 u32 match u32 0 0 
flowid 1:10

where 1:99 doesn't exist as an htb class.
