If funds are not an issue I would build a DMZ and put it there.  If fundage 
is a problem I would harden the web server as much as possible and put it 
outside.  If you put it on the inside and someone uses a web server exploit 
that gives them root/admin rights, your internal network becomes someones new 
playground.  If you put the web server on the outside and it gets exploited 
it's not near as much of a headache.

I don't agree with their logic...

But if the webserver is on the inside and gets rooted, getting internal IP's 
is a trivial thing.

With the number of Oracle exploits going around now I would be carefull here.

I think you're right.
But a DMZ, if you can afford building one, would be a better choice.
