mod_rewrite exlude

[canadabeeau]

I have this mod_rewrite in my root folder

Options +FollowSymlinks
RewriteEngine On
RewriteRule ^([a-zA-Z0-9]+/)*[a-zA-Z0-9]+$ /index.php?uri=$0

 

I need to exclude directories which are real folders from the mod_rewite so they can have their own mod_rewite, i.e. in root/administration/ i have index.php which should be able to pull its own $uri not the ones from the root $uri (mod_rewrite), at the moment its $uri is from the root-index.php

 

if this is not clear or if anyone can help please post,

 

thanks in advance
