Pity you didn't make that clear earlier :-/
You need a shared-network block around the two subnets. Without that 
you are telling the server that you have two completely different 
networks with those subnets - with the shared-network you are telling 
it that you have ONE physical network with two subnets.

Why things are probably failing is that the server is working out 
that the client is in the subnet based on the 
interface the request came in on or the GIAddr if it came via a relay 
agent. Because it doesn't know that the subnet is on 
the same wire, it cannot allocate any addresses from the pool in that 
subnet - and so you get no free leases if the client isn't a member 
of the first class.
