You're running into an order of operation issue.  IOS DHCP starts handing out 
addresses from the end of the DHCP pool so 10.10.202.254 was the first address 
it handed out.  My guess would be you're interfaces were up and you configured 
the DHCP pool first and then configured the exclude addresses.    By the time 
you got around to entering the exclude addresses the phone had already been 
assigned the top end of your exclude range.  The easiest way to ensure this 
doesn't happen is to

1.  Shut the interfaces attached to the phones
2.  Configure your exclude addresses
3.  Configure your DHCP pool
4.  no shut your interfaces

The easiest way to get things back on track is to shut the interfaces, run a 
"clear ip dhcp *" then configure your additional exclude command and then no 
shut your interfaces.
