Best practice in this case is to reserve (administratively) a segment of 
the network for reservations so that you do not have split the pool(s) 
around them. So assuming that your .10 address is the last one of your 
reservations, you would start your pool at .11.

If that's not possible for whatever reason, then what Chris Buxton 
described in his message at 1:57 pm Pacific time will work. (That is, 
you do not need to, and in fact should not, include pools for your dhcp 
reserved addresses.)

hope this helps,
